i have created spring rest services using eclipse IDE. It works fine in eclipse when i run using Debug configurations however when I export it as a executable JAR and run using below command
java -jar cs.jar
it gives me below error:
org.springframework.context.ApplicationContextException: Unable to start embedde
d container; nested exception is org.springframework.boot.context.embedded.Embed
dedServletContainerException: Unable to start embedded Tomcat
at org.springframework.boot.context.embedded.EmbeddedWebApplicationConte
xt.onRefresh(EmbeddedWebApplicationContext.java:124)
at org.springframework.context.support.AbstractApplicationContext.refres
h(AbstractApplicationContext.java:474)
at org.springframework.boot.context.embedded.EmbeddedWebApplicationConte
xt.refresh(EmbeddedWebApplicationContext.java:109)
why it's not working as a jar?
You need to check if you have included servlet-api jar in your classpath, if yes, delete it.
If servlet-api is in classpath, it is included in WEB-INF/lib and then the error is thrown because servlet container has already servlet api jar.
Delete servlet-api dependency from maven or gradle if exits or if this dependency is adding by any other module then exclude servlet api dependency like below
<dependency>
<groupId><groupId></groupId>
<artifactId><some dependency></artifactId>
<version><version></version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>

I'm building a web app using Vaadin and it needs to communicate with several REST APIs. I've set it up in IntelliJ with Maven. I was thinking for the REST client I would use GSON to parse the JSON objects I'd be receiving from the open APIs, however, the application crashes due to a servlet exception error.
Caused by:
java.lang.ClassNotFoundException: com.google.gwt.json.client.JSONObject
I've added the GSON dependency to the pom.xml:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
And have tried changing the module settings from Provided to Compiled to Runtime but with no change.
I'm just stumped as to why the GSON jar appears in the project dependencies within IntelliJ using Maven but fails on run time. I've seen references to Eclipse and including the jar in the classpath but, again, I'm using IntelliJ/Maven to build my Vaadin project and satisfy dependencies.
Any help is greatly appreciated!
Add below dependency in your classpath:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.3.0</version>
</dependency>
I am trying to use spring boot 1.1.5 and apache spark 1.0.2 together in project. Look like apache spark uses Jetty container internally and I have configured spring-boot to use Tomcat container. However application startup fails with some securityException at root cause. If I see full stack trace looks like spring boot trying to initialize "jettyEmbeddedServletContainerFactory" which it shouldn't in first place. It probably picks it up from classpath due to jetty presence via spark. If I exclude jetty from spark and run again I don't see same error again but then SparkContext initialization fails due to not finding jetty. How do i tell spring-boot runtime to look for "TomcatEmbeddedServletContainerFactory" instead of jetty one?
I got "java.lang.SecurityException: class "javax.servlet.http.HttpSessionIdListener"'s signer information does not match signer information of other classes in the same package"
To fix this issue I was need to remove all javax.servlet dependencies.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.3.1</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</exclusion>
<exclusion>

#Joakim Erdfelt, Thanks.
I was just waiting to see if someone is familiar with this situation and if it's just a small configuration change. As it turns out it is! #Configuration
#EnableAutoConfiguration(exclude={EmbeddedServletContainerFactory.class})
public class MyConfiguration { }
I defined my own "EmbeddedServletContainerFactory" bean as a "org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContaine‌​rFactory" and it started working as I expected.
I have a Java EE project which is meant to run on Glassfish 4.1. I want to use Selenium to collect information from some web pages, i.e. I need to include Selenium in the deployment (not just for tests).
I am using Eclipse IDE and have previously utilized the incremental deployment function in Eclipse to automatically deploy all saved changes to the project. But when I included (with Maven) the dependencies for Selenium incremental deployment stopped working. The project can still be deployed to Glassfish but I have to restart Glassfish between every change. I get the following error in Eclipse:
Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: java.util.concurrent.ExecutionException: com.sun.faces.config.ConfigurationException: Unable to parse document 'bundle://136.0:1/com/sun/faces/jsf-ri-runtime.xml': DTD factory class org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl does not extend from DTDDVFactory.. Please see server.log for more details.
org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl is included with Selenium as a transitive dependency (xerces:xercesImpl:2.11.0).
Here are my Maven dependencies:
<dependency>
<groupId>org.jboss.arquillian.selenium</groupId>
<artifactId>selenium-bom</artifactId>
<version>2.44.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
</dependency>
I hope there is a solution to this but after reading Jens Schauder's response in Dealing with "Xerces hell" in Java/Maven? I'm afraid there might not be. Anyone?
I currently can't reproduce the issue with a simple project, did you make sure that you don't have any other dependencies which are importing another version of xercesImpl?
You can try to place the xercesImpl-2.11.0.jar and the transitive dependency xml-apis-1.4.01.jar in the lib folder of your Glassfish domain and exclude it from your dependencies like this:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
<version>2.44.0</version>
<exclusions>
<exclusion>
<artifactId>xercesImpl</artifactId>
<groupId>xerces</groupId>
</exclusion>
</exclusions>
</dependency>

when I run tomcat and the war is deployed I get :
NoClassDefFoundError : org/apache/commons/collections/map/LRUMap
Invocation of init method failed; nested exception is
java.lang.NoClassDefFoundError:

~[spring-beans-3.1.0.RELEASE.jar:3.1.0.RELEASE]
What is strange is that I got the commons-collections-2.1.jar (I even tried 3.1) in my WEB-INF lib folder.
Edit :
I did copy the commons-collections from WEB-INF/lib to Tomcat lib and it seems to work. However I won't be able to do that on the production server, why isn't it taking my WEB-INF/lib version ?
Ok so I did put version 3.2.1 of commons-collections and the error disappeared. I unfortunately still don't know which library is depending on this version. Even mvn dependency:tree didn't help ...
I had this exception when I was with xdoclet on dependencies.
If you are with this dependency, just exclude it.
I have the same probleme, maybe it's too late to approve the answer but it's still benefitial for people who will have this problem in the futur.
So I exclude commons-collections from net.sf.jasperreports, after that the tomcat runs perfectly whithout any problem.
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>4.1.1</version>
<type>jar</type>

<exclusion>
<artifactId>commons-collections</artifactId>
<groupId>commons-collections</groupId>

I'm trying to run tests for my webapp. I've used Spring and Hibernate for it. But running mvn package results in an ClassNotFoundException in the test tasks: java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource
I already tried adding this into my pom.xml, but without success:
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
<scope>test</scope>
</dependency>
What to do here?
UPDATE
mvn -X clean package: http://paste.ubuntuusers.de/raw/409407/
I don't see any problem with DBCP here. Rather log says about some problems with autowiring Spring beans, starting with missing com.example.model.ArticleService. Declare such missing beans as Spring components and should be OK.
