I'm in the process of maven-ising and old ant app that we have. I have added a dependency on log4j-1.2.8 in my pom (as it is required for compilation). However, when I try and deploy on jboss (stuck with version 4.0.2) I get the following:
org.jboss.deployment.DeploymentException: Failed to find module file: log4j-1.2.8.jar

I'm not sure who setup jboss and I don't have any control over its configuration. I can however see it has the following log4j jars in various locations:
/opt/jboss-4.0.2]$ find -L . -name '*log4j*.jar'
./client/log4j.jar
./server/minimal/lib/log4j.jar
./server/all/lib/log4j.jar
./server/default/lib/log4j-1.2.16.jar
./lib/log4j-boot.jar
Does anyone have any idea what is setup wrong? I know the old ant app used to work on the same jboss server. I have tried using various versions of log4j in my pom (i.e. those found in the jboss directory), and even tried adding a dependency on jboss-logging - but i'm just guessing here.
Cheers!
Consider adding your log4j dependency as <scope>provided</scope>, as it is provided by your application server and so is not required in the artifact you deploy.

My application is running on Tomcat 7.
I'm trying to read emails from inbox, and for that I use a normal Java class.
There is also a Servlet that calls the method readMails in the mentioned class.
Now I get an exception:
java.lang.ClassNotFoundException: javax.mail.MessagingException
...
I use IntelliJ IDEA with Maven, I changed the dependency of javax.mail a lot (see http://mvnrepository.com/artifact/javax.mail), but the exception keeps coming up.
I've also changed the Version of Tomcat (7 and 8), and the version of "Project SDK" (1.7 and 1.8) and "Project language level" (7 and 8).
I've read somewhere that there is a difference between reading emails via IMAP with normal Java application and running it on Tomcat.
In a previous project I read emails successfully with a normal Java application.
Can anyone help me with this exception?
JavaMail API is not included by default among Tomcat libraries.
Make sure that JavaMail dependency (mail-X.X.jar) is either packaged together with your application (in WEB-INF/lib) or is in a folder that Tomcat class loaders read (for example $CATALINA_HOME/lib), as described here:
http://tomcat.apache.org/tomcat-7.0-doc/class-loader-howto.html
Thanks, it works now.
I put the jar file (javax.mail: javax.mail-api-1.5.4.jar) downloaded by maven (.m2/repository/ ...) into WEB-INF/lib (in my project).
I also needed to put another jar file into WEB-INF/lib (com.sun.mail: javax.mail-1.5.4.jar) due to this exception:
java.lang.NoClassDefFoundError: com/sun/mail/util/MailLogger
javax.mail.Session.initLogger(Session.java:226)
javax.mail.Session.<init>(Session.java:210)
javax.mail.Session.getDefaultInstance(Session.java:321)
I added
<packaging>war</packaging>
to my pom.xml. This way maven puts the dependencies in the target folder.
I'm trying to override a dependency version through a maven profile. I did a test installing the war and it works. The problem is when I run the war using maven tomcat plugin. I wanted to check which version of the jar is used, but I have no idea where it reads the jars from. I cannot find anything useful on available documentation..
Any help?
I believe this page will help you to understand: http://tomcat.apache.org/maven-plugin-2.2/tomcat7-maven-plugin/adjust-embedded-tomcat-version.html
Use the dependencies section in plugin section
HTH
I have a plain Felix based OSGI Environment on which I have deployed a bundle, which has an Embedded ActiveMQ Broker. I want to have another bundle deployed on the same OSGI environment, which shall have an embedded jetty on which the ActiveMQ Web Console War file will be deployed.
I tried by spawning the embedded jetty and deploying the war file as part of this bundle (bundleActivator Start Method), but it gives me the following exception -
Caused by: java.lang.ClassNotFoundException: javax.servlet.ServletContextListener
at java.net.URLClassLoader$1.run(Unknown Source)
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:431)
at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:393)
I have the Servlet-API jar in the bundle classpath (imported the package and is being resolved while bundle deployment). I have also noticed that the activemq-web-console-5.10.0.war file's lib folder also contain the Servlet-API jar.
So, I thought may be because of duplication of the Servlet-API jar, it it throwing this exception and removed the Servlet-API jar from my bundle classpath (removed the import, also tried by undeploying the bundle exporting that package) but in this case my bundle did not get deployed and I received wiring exceptions (as Jetty dependencies clearly need that jar).
I donot want to unpack and pack again the war file and try.
Please Note: this war file got deployed successfully on Karaf, but I am failing it to deploy on OSGI env based on plain Felix with my own felix launcher.
Please help !
EDIT
The bundle containing embedded jetty gets deployed, but when I start it, while Jetty is starting (deploying the war file) above exception is being thrown
END EDIT
hmm, rebuilding Karaf from scratch there?
Anyway you'll need a webcontainer running with your felix environment to have the web-console running.
Therefore you need to either have the felix http-service running, or the Pax Web Bundles (as in Karaf).
The next thing you'll stumble upon will be to have a satisfying and easy logging. This you'll either need to create yourself or deploy the Pax Logging bundles (again as in Karaf).
Any reason not to stick to Karaf where you have all infrastructure bundles available?
Im currently develop bundles for karaf and have some questions...
I wrote a bundle/webservice based on cxf, I try to deploy it in karaf but it could not start that bundle because it could not resolve some packages e.g.
org.osgi.framework.BundleException: Unresolved constraint in bundle org.springframework.aop [56]: Unable to resolve 56.0: missing
requirement [56.0] package; (&(package=org.aopalliance.aop)(version>=1.0.0)(!(version>=2.0.0)))
so here is a question, this package dependency comes from spring-aop (3.1.0.RELEASE), so where is the problem? what dependency is missing? how can I solve such problems?
In that case i did not clearly understand the development process. should i deploy all missing bundles in deploy? because i would like to keep thirdparty libs spereated from my developed bundles. And what bundles i have to deploy? Is it a trial and error process? Is there a common way to let maven do the dependency stuff?
I discovered a folder "system" and read on the docu that it is a repository like maven, is it for the features?
I had for test cases a karaf with some pre deployed bundles and put my webservice bundle into it, but again execeptions...
Caused by: java.lang.ClassNotFoundException: javax.servlet.http.HttpServlet
What dependency is missing?
I already read the tutorial about camel and karaf, but it did not explain the deployment stuff, so could anyone suggest me a good tutorial?
Thanks!
Chris
Short answer
Scroll down to the bit referring to "camel-cxf" and run the two commands features:addurl and features:install. I have a feeling this will resolve all your problems.
spring-aop
On Karaf console type:
exports | grep org.aopalliance.aop
I think you'll see lines like:
XX org.aopalliance.aop; version=3.1.0.RELEASE
So while the spring-aop bundle has the right packages they're the wrong version, the range being requested is >=1.0.0 and <2.0.0, so 3.1.0 doesn't satisfy that.
Deploying/Installing
You can drop bundles into ${karaf.home}/deploy or use the console.
You can install maven bundles from the Karaf console with:
install -s mvn:groupId/artifactId/version/packaging/classifier
Where -s starts the bundle and packaging/classifier are optional.
You can find a lot of OSGi ready maven dependencies here http://ebr.springsource.com/repository/app/ - I had a quick look but your spring aop dependency is very old, what version of CXF are you using?
Read up about Karaf features - they're basically XML files that list suites of bundles that can be installed. Very useful for deploying large numbers of bundles and they can be installed into a maven repository.
There are some standard features available in Karaf, try:
features:install war
This will give you a jetty webcontainer and may resolve your ClassNotFoundException: javax.servlet.http.HttpServlet as long as it's the right version
Camel also has a features file which probably sort all your issues, try this:
features:addurl mvn:org.apache.camel.karaf/apache-camel/2.9.0/xml/features
features:install camel-cxf
Tutorials
There's quite a bit available, some on http://karaf.apache.org and http://fusesource.com but also take a look at the PDF manual that comes in the Karaf distribution.
Always beware that info may be out-of-date
Please post your MANIFEST.MF file. I think you didn't not mention the tag in maven-bundle-plugin dependency.
I have a Jersey (1.4) app deployed on Tomcat 5.5, when Tomcat starts up I can see its loading all the resources and providers. But as soon as I access any of the web services I get this strange error
java.lang.NoClassDefFoundError: com/sun/jersey/spi/inject/Errors$Closure
I spent good long time finding out what's going on but had no luck.
I converted maven project into eclipse project using mvn eclipse:eclipse -Dwtpversion=1.5.
Any ideas?
I got this error when I also had a nuxeo related dependancy in my maven pom.xml, which itself has a dependency on jersey libraries, but at an earlier version (1.1.5 to be specific).
I changed the pom to depend on the latest version of jersey-core, jersey-server and jersey-client dependencies and ran mvn eclipse:eclipse and the problem went away!
There must have been a class clash involved.
