I am trying to run my application which contain JAX WS (2.1) Webservice using JDeveloper 11g R2(11.1.2.3.0) in JDK 1.6.0_31-b05. The error is coming from #WebService annotation present on the class.
When I am running the application, I am getting below error,
java.lang.IllegalArgumentException: Argument(s) "type" can't be null.

It seems that embedded Web Logic is using the internal libraries instead of provided one from JDK. The classes RuntimeModeler or TypeReference are present in JDK rt.jar starts with package com.sun.xml.ws.internal. Weblogic is picking these classes from glassfish.jaxb_1.0.0.0_2-1-12.jar & glassfish.jaxws.rt_1.2.0.0_2-1-5.jar, but these jars are not part of my application.
I have already used weblogic.xml with below tag,
<prefer-web-inf-classes>true</prefer-web-inf-classes>
I tried adding jaxws-api.jar & jws-api.jar in DefaultDomain/lib directory, but that didn't work
Any clue how to resolve this exception or how to force weblogic to use jdk runtime classes? The same application work properly on stand alone weblogic.
I had the same problem and found the answer here: http://www.intropro.com/resources/blog/66-argument-s-type-can-t-be-null
In short - the problem appears because you have jaxb-impl in you classpath which overrides WebLogics own jaxb, You may not explicitly refer to this dependency from your pom.xml, but some of your other dependencies do.
In my case I had apache-cxf as maven dependency and it had jaxb 2.1.13 as sub-dependency with scope "compile". All I had to do is exclude this apaches jaxb and add my own dependency with scope "provided" to explicitly use WebLogics jaxb.
in pom.xml it looked like this:
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>2.7.2</version>
<exclusions>
<exclusion>
<artifactId>jaxb-impl</artifactId>
<groupId>com.sun.xml.bind</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<scope>provided</scope>
<version>2.1.13</version>
</dependency>
You can use eclipses "Dependency Hierarchy" tab in pom.xml view or simply command line "mvn dependency:tree" to find out how jaxb-impl made it to your classpath.
In my case, i had a typo in the arguments of the operation, where two arguments had the same webParam name. Modified that and deployed, issue was resolved.
Have you tried listing the correct jar in the manifest class-path: attribute? You could also put the jdk classes in the app and try using a FilteringClassLoader to specify which classes to use from the app rather than system classloader.

I changed some existing projects from ant to maven projects.
So far so good.
All projects do have the same groupId.
Theres a project with name "ServerBase" and artifactId "server-base".
Within this project theres an abstract class "BaseService" which defines a logger via:
import org.jboss.logging.Logger;
[...]
protected Logger log = Logger.getLogger(this.getClass());
Theres another project with name "Server" and artifactId "server".
Within this project theres a class ConfigurationDAOImpl extending the BaseService-Class above.
Within ConfigurationDAOImpl the logger log is used for creating some outputs.
Within the "Server"'s POM file I have declared:
<dependency>
<groupId>com.tcom.amadeus</groupId>
<artifactId>server-base</artifactId>
<version>${project.version}</version>
</dependency>
Under BuildPath the dependency is shown very nice under MavenDependencies. I removed the old dirct/natural/ant-dependency from build path before.
If I remove it I am getting very much errors about missing classes etc.
But although I do have this dependency I am getting the followin error in eclipse (under tab markers):
The type org.apache.commons.logging.Log cannot be resolved. It is indirectly referenced from required .class files
Resource: ConfigurationDAPImpl.java
Path: /Server/src/main/...
Location: Line 24
Type: Java Problem
I tried removing the dependency and add it again but without any luck.
Both projects do refer to JAVA 1.8.
Both projects have been build with targets clean an package multiple times.
Both projects have been updated by Righclick or pressing F5.
I am using Eclipse Version: Neon.1a Release (4.6.1)
I am using apache-maven-3.3.9
I am using m2e Plugin.
Any further help would be grateful.
Thanks in advance.
There are two ways to 'solve' this:
1)
explicitly add the required dependency within the server-projects pom-file:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
</dependency>
2)
change the scop of the required dependency within the server-base-projects pom file from up to now 'provide' to 'compile' or erase the scope tag at all such that the default scope is used by maven (which I guess is 'compile')
old:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<scope>provided</scope>
</dependency>
new:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<scope></scope>
</dependency>
or:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
</dependency>
Some background to this from documentation:
http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Transitive_Dependencies
provided This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example,
when building a web application for the Java Enterprise Edition, you
would set the dependency on the Servlet API and related Java EE APIs
to scope provided because the web container provides those classes.
This scope is only available on the compilation and test classpath,
and is not transitive.
Thanks all.
It looks like apache logging library is not brought transitively from your server-base project. Check if in project server under MavenDependencies you see commons-logging (apache logging) jar. If not, then add this as your maven dependency in server-base project.
Repeat the above for all jars that server-base depends on.
I am running into the following error
java.lang.NoSuchFieldError: WRITE_DURATIONS_AS_TIMESTAMPS
at com.fasterxml.jackson.datatype.joda.ser.DurationSerializer.<init>(DurationSerializer.java:28)
at com.fasterxml.jackson.datatype.joda.ser.DurationSerializer.<init>(DurationSerializer.java:25)
at com.fasterxml.jackson.datatype.joda.JodaModule.<init>(JodaModule.java:45)
I checked to see what versions of jackson-datatype-joda are available. It appears that maven has excluded all version mismatches.
Any other reason this might cause serialization errors?
The problem is that among the maven dependencies (mind that it could be a transitive one) you have incompatible versions of jackson-datatype-joda and jackson-databind. Incompatible in the sense that jackson-databind's SerializationFeature class is missing the WRITE_DURATIONS_AS_TIMESTAMPS field. To see what dependencies maven brings you can run the following command in the terminal (or you can use an IDE's maven plug to search and analyse the maven dependency tree):
mvn dependency:tree | grep databind
the outcome will most probably be something like:
[INFO] | +- com.fasterxml.jackson.core:jackson-databind:jar:2.4.1:compile
The version of course can vary but the important thing is that the WRITE_DURATIONS_AS_TIMESTAMPS field is only available since version 2.5
You can exclude a transitive dependency like this:
<dependency>
<groupId>group.id</groupId>
<artifactId>artifact-id</artifactId>
<version>${artifact.version}</version>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</exclusion>
</exclusions>
</dependency>
If it's not a transitive dependency you need to update version of jackson-databind.
I got it resolved by using following dependency as this dependency has overridden any other version used:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-joda</artifactId>
<version>2.5.3</version>
</dependency>
I had same error. I had included all jackson*2.7.0 libraries under WEB-INF/lib/ and i was still getting that error. I am using wildfly 8.2 and it had jackson 2.4.1 libraries under modules and somehow it was loading 2.4.1 jars from that location. So I had to manually upgrade them to 2.7.0 which fixed the issue. I was under impression that if I did not mention it to load jackson jars in deployment configuration file, it would not load wildfly jars. I guess I was wrong.
I thought that the order of Maven dependencies doesn't matter before and regard this as a pro of it. And this is my old pom.xml's dependencies:
<dependencies>
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.19</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.ext</groupId>
<artifactId>jersey-spring3</artifactId>
<version>2.19</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-moxy</artifactId>
<version>2.19</version>
</dependency>
</dependencies>
It works well, and today I wanna move spring dependency to the bottom so that those jersey related can be together. However then I can no longer make it working, my Jetty complains:
[ERROR] Failed to execute goal org.eclipse.jetty:jetty-maven-plugin:9.3.0.M1:run (default-cli) on project mtest: Execution default-cli of goal org.eclipse.jetty:jetty-maven-plugin:9.3.0.M1:run failed: A required class was missing while executing org.eclipse.jetty:jetty-maven-plugin:9.3.0.M1:run: org/apache/commons/logging/LogFactory
That is really confusing, so do I have to concern about dependencies order? How do I know the correct order?
The order of dependencies does matter because of how Maven resolves transitive dependencies, starting with version 2.0.9. Excerpt from the documentation:
(...) this determines what version of a dependency will be used when multiple versions of an artifact are encountered. (...) You can always guarantee a version by declaring it explicitly in your project's POM. (...) since Maven 2.0.9 it's the order in the declaration that counts: the first declaration wins.
To expand upon the other answer (which states that the declaration order affects Maven's dependency mediation for transitive dependencies), there are a few tools you can use:
mvn dependency:tree [-Dscope=[runtime|test]] will show you what dependencies will be available for the selected scope. See here for details
mvn dependency:build-classpath gives you order in which dependencies are available on your classpath (if two or more classpath entries have the same class, the earlier one wins). See here for details
I don't know much about your situation, but it's often the case that you wind up with the wrong version of 1 or more jars at compile/runtime. Declaring your own version of the library in question or locking down the version with <dependencyManagement> are options here.
Now to answer your other question - how do you know what the right order is when declaring dependencies?
My suggestion - the right declaration order is the one that gets you the versions of the dependencies you want, in the order you want them in. Use the tools above to check your dependencies, and tweak the declared order if necessary.
Note that most jars contain disjointedly-named classes, so the exact order in which jars appear on your classpath is usually not that important. The only exception I've noticed is some jars in SLF4J which intentionally shadow classes from the other logger libraries it's intended to replace.
This problem was mentioned in several sources around the web but I was unable to solve it with solutions provided there.
PROBLEM:
The following error is thrown from log4j when issuing mvn gwt:run:

<dependency>

<artifactId>jcl-over-slf4j</artifactId>
<version>${slf4j.version}</version>
<scope>runtime</scope>
</dependency>
What's more, I exclude commons-logging from spring and other projects that depend on it.
(not satisfying) SOLUTION:
Logging works fine only when log4j, slf4j-api, slf4j-log4j12 and jcl-over-slf4j jars are put in my WEB-INF/lib directory but only when jcl-over-slf4 is not in the project's classpath (i.e. I comment out the last mentioned dependency).
When jcl-overl-slf4j is included in maven dependencies (see above) it is not only added to target's lib directory but also included in project's classpath. It causes the error. This jar is necessary to be put in lib but the error disappears only when it is not included in the classpath. maven-dependency-plugin is used to work this problem around by copying it into lib directory and skipping maven dependency.
This solution is obviously just a workaround as all four jars - log4j, slf4j-api, slf4j-log4j12, jcl-over-slf4j - are mentioned in many standard examples of gwt and spring projects.
Could you explain why is it behaving that way and how could I solve this with normal inclusion of jcl-over-slf4j in maven dependencies?
Jetty treats org.apache.commons.logging as a system class, i.e. it loads it from the system class loader (i.e. the classpath) in priority over the webapp's WEB-INF/lib. In your case, org.apache.commons.logging is provided by jcl-over-slf4j. So, code in your webapp calls Commons Logging which is then loaded from the system class loader, and it probably initializes SLF4J using the class's class loader (as opposed to the current thread class loader), which thus uses code from slf4j-log4j12 and log4j from the system class loader. Later on, code in the webapp calls into Log4j (possibly through SLF4J) to initialize the logging configuration, and it then uses the JARs from the webapp's WEB-INF/lib (as expected). When it comes to put everything together, then comes the issue, with classes loaded from different class loaders.
Now to solve the issue: it's not straightforward.
Simply put, classloading in DevMode is a mess (see https://docs.google.com/document/d/1bWfafaPA0m0Z1Swodnx7m3QTv31OdqFkE7aeadN_2BU/edit?usp=sharing where I tried to document it).
To solve your issue, you'd have to either use your own ServletContainerLauncher in DevMode with your own classloading rules, or more simply run your webapp in another servlet container (e.g. mvn jetty:run or mvn tomcat7:run, or whatever). Then you'd run DevMode in -noserver mode.
It's a slightly more complex setup, but it has the big advantage of being exactly the one you'll need for SuperDevMode; and SuperDevMode will replace DevMode this year (DevMode is dead already in Firefox, and in Chrome on Linux –basically, it's dead on Linux–, and support will be removed from Chrome on other platforms later this year, leaving only one working platform: Internet Explorer on Windows).
I am trying to run sample guessnumber-jsf from Java EE tutorial. It is here: https://svn.java.net/svn/javaeetutorial~svn
There is no dependencies in pom.xml. So output file has no .jar file. When I try to put javaee-api-7.0-b83.jar inside tomcat/lib or WEB-INF/lib/javaee-api-7.0-b83.jar, nothing changes.
When I try to open
localhost:8080/guessnumber-jsf/faces/greeting.xhtml
I get ClassNotFoundException. Where can I get list of jars that I need for faces tutorial? How can I connect them?
You can't put that Java EE jar in Tomcat and expect it to magically morph into a Java EE server.
That particular jar only contains the APIs to link against (eg "headers" in C/C++ terminology). It does not contain any implementation.
The easiest thing to do is to dish Tomcat and download TomEE instead. Optionally download GlassFish.
These will all already contain all the functionality you need and nothing will have to be put into WEB-INF/lib. (if using Maven put the Java EE 6 GAV as a dependency with scope provided in your pom).
If you are using a Maven project you can fix this error by adding the following dependency:
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.2.7</version>
</dependency>
Adding to the answer of Mike Braun, the Java EE 6 GAV for the web profile is:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>6</version>
<scope>provided</scope>
</dependency>
Specifically note the scope: "provided". This means your Maven project will link against this, but it expects your runtime to have the implementations. For TomEE, GlassFish, JBoss AS 7.x, etc this is indeed the case.
In your classpath (.classpath) make sure you have entry like
<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
