I'm trying to deploy a EAR file to Jboss Wildfly (8.1.0) but im getting the following exception:
Caused by: java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;
My EAR file contains an EJB jar which contains mybatis (version 3.2.7) persistnence Units which have a Dependency on the cglib (version: 3.1).
This very same ear file deploy's and works without issues in JBoss 7 (version 7.1.1)
Based on the error saying the method isnt found but i know the class and method are there it must be some class conflict in the new version of jboss.
I managed to find the answer after some investigation and dissecting of the ear file. The problem was the asm.jar included in my EJB jar as a sub dependency of cglib. There is a class conflict between the jboss included jar and the EAR jar. To fix it simply add a maven exclusion on the cglib dependency for the asm sub dependency.

I'm trying to run JPA servlet on Tomcat 8.
From my servlet I call method of a class named QueryDB.class located in another Eclipse project (JPA project, not WEB project).
But tomcat throws
SEVERE: Servlet.service() for servlet [MyRESTService] in context with path [/AutomationWeb] threw exception [org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/persistence/Persistence] with root cause
java.lang.ClassNotFoundException: javax.persistence.Persistence
at java.net.URLClassLoader$1.run(Unknown Source)
...
Exception is thrown at line EntityManagerFactory emf = Persistence.createEntityManagerFactory( "AutomationDB_JPA" ); in QueryDB.class
I'm using Eclipse Mars with Maven. I have EclipseLink in my pom.xml defined:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.6.1</version>
</dependency>
I have following jars in my Application's WEB-INF/lib:
eclipselink-2.6.1.jar
javax.persistence-2.1.0.jar , it has javax/persistence/Persistence.class inside
There is no other SEVERE messages in the tomcat log.
What's wrong with this setup?
I also tried adding the persistence jar to apache-tomcat-8.0.28\lib , but got the same error.
Update: I moved Persistence.createEntityManagerFactory call to the servlet itself and got no classloader exception. So the question changes: why classloader used for QueryDB.class is different from servlet's classloader? Also, why classloader used in QueryDB.class does not see the Persistence.class, which is seen by the servlet's classloader?
Ok I've found a solution.
Excluded my JPA project from tomcat VM classpath
Converted my JPA project to the Utility project
Modified Deployment Assembly in my Web project properties so that it
will accept JPA project as .jar archive into WEB-INF/lib
I have no classloader exception anymore.
A.war -> Is a simple spring boot REST app using version 1.2.6.RELEASE ( internally using spring 4.1.7 RELEASE, jackson 2.4.6 )
B.jar -> Is a wildfly9 shared module (stored in wildfly/modules) which is packaged using maven shaded plugin containing spring framework (without spring boot meaning using the old way of adding spring projects dependencies) and jackson classes of same version as above. (Its shaded because non-spring and non-container projects can just add this jar in their class-path and use it - it works)
A.war has maven dependency scope <provided> on B.jar and has jboss-deployment-structure.xml with <dependencies> <module name = "B"> </dependencies>
A.war deployment fails with below error.
Note: A.war deploys perfectly fine when i remove B.jar jboss dependency. So adding B.jar is causing this issue. And If i don't use spring boot in A.war (meaning if i use simple spring webmvc and context dependencies directly) with B.jar jboss dependency, A.war deploys perfectly too
Can anyone explain me what the error below says and how can i investigate more ?
As far as my understanding on wildlfy classloading, A.war and B.jar should be loaded in different module class loaders, Is A.war complaining about jackson classes of B.jar here in the error ?

After investigating more jboss classloading behavior, jackson classes inside B.jar are conflicting with same jackson classes from jboss restesay module.
so after excluding them in jboss-deployment-structure.xml as below this problem is fixed..
<exclusions>
<module name="org.jboss.resteasy.resteasy-jackson-provider"/>
<module name="org.jboss.resteasy.resteasy-jackson2-provider"/>

I am using JDK 1.7 with Maven 3.0 for my project.
When I have the following in pom.xml
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>compile</scope>
</dependency>
I am getting the following while deploying to Weblogic 10.3.6 integrated with Eclipse
WARN (org.hibernate.cfg.beanvalidation.TypeSafeActivator;141) HHH000274:
Unable to apply constraints on DDL for test.entity.Employee
java.lang.NullPointerException at
org.hibernate.cfg.beanvalidation.TypeSafeActivator.applyDDL(TypeSafeActivator.java:172)
If I remove javaee-api dependency, then I do have issues when I compile project using mvn compile with errors like
[ERROR] /domain/view/EmployeeNameConverter.java:[29,76] cannot access
javax.el.ELContext
class file for javax.el.ELContext not found
[ERROR] /EmployeeNameConverter.java:[28,55] cannot access javax.el.ELResolver
class file for javax.el.ELResolver not found
More details here
How can I resolve this issue?
Like we've worked out in the comments Weblogic 11g doesn't support Java EE6. So one solution can be using Java EE5 instead.
The error is:
SEVERE: Servlet.service() for servlet [jsp] in context with path [] threw exception [Unable to compile class for JSP] with root cause

The project is using a war overlay, in which the overlaid project has the juel-impl jar, which is necessary for its use of shindig. Any way to use jstl in the child project jsp pages?
Seems you have two rivaling EL APIs in your class path, tomcat's and another one from your application. Your war file must not contain an el-api.jar or juel-api.jar. Make sure to exclude those dependencies.
The Juel 2.1.3 jar is a combination of the following Jars juel-impl.jar, juel-spi.jar and juel-api.jar.
We had the same issue when we included juel 2.1.3 jar in the pom and deployed in tomcat 7.
The issue is resolved by removing Juel 2.1.3 from pom and by adding only juel-impl.
<dependency>
<groupId>de.odysseus.juel</groupId>
<artifactId>juel-impl</artifactId>
<version>2.2.6</version>
</dependency>
you need to also add
<dependency>
<groupId>de.odysseus.juel</groupId>
<artifactId>juel-api</artifactId>
<version>2.2.6</version>
</dependency>
The juel 2.1.3 jar contains the javax/el interfaces and are also a part of jsp-api jar.
I hope this will help.
I'm using Apache CXF version 2.4.0. I'm trying to create a Restful service.
The below example works in 2.3.4 but does not work in 2.4.0. What should I do different in beans config file?
When I include the below xml line in my bean config file.
<import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml" />
I get the following stacktrace error:
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Failed to
import bean definitions from URL
location
[classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml]
Offending resource: ServletContext

exception is

cannot be opened because it does not
exist at
org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68)
My POM dependency is below. This will work for 2.3.4 but not for 2.4.0. Any suggestions? Is that xml extension line deprecated or included in another jar?
<dependency>
<groupId>org.apache.cxf</groupId>

It's no longer needed. With 2.4.x, most of the META-INF/cxf files are no longer needed and can be removed. Really, the cxf.xml one is the only one needed.
Here is the CXF information about embedding cxf inside spring in version 2.4 and above.
