Deploying a mavenised seam project, noClassdefFound org.jboss.el.util.ReflectionUtil

While deploying a mavenized application consisting of a parent project, ejb jar project and a web project I have following stack trace in Jboss As ,5.1.0.GA.

I checked that I have the dependency for jboss-el-1.0_02.CR4.jar and the library also contains the class org/jboss/el/util/ReflectionUtil.

Any ideas ? If required, I will also post the pom 开发者_运维技巧files of all the projects. They are based on the seam-refimpl project mentioned in the seam FAQ section.

Here the link http://code.google.com/p/seam-maven-refimpl

I figured out that my ear plugin was including the jboss-el.jar file on the root level with other modules. This doesn't work. Jboss requires it inside the lib directory in the ear package.

Following configuration option in ear plugin configuration fixed the problem. This way, all the dependencies, except which are mentioned in the modules will go to the lib directory in side the archive.

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-ear-plugin</artifactId>
        <version>2.4</version>
        <configuration>
            <defaultLibBundleDir>lib</defaultLibBundleDir> 
            ...
        </configuration>
</plugin>

I have a hunch that JBoss 5.1 already includes a copy of the org.jboss.el stuff. If you also package a copy of those same classes in your application, then you may experience some classloader weirdness.

Try removing all copies of ReflectionUtil from your application, and see if that helps.
