ApacheCommons/lang/StringUtils not found

As known, the JBoss AS 7.0.0 provides some apache-commons dependencies out of the box. They are located in the 

$JBOSS_HOME$\modules\org\apache\commons\lang\main

So, I tried to use these provided dependencies by declaring the following dependency in my pom.xml:

<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>${commons.version}</version>
    <scope>provided</scope>
</dependency>

And when I tried to use of of its classes I got:

java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils
    com.badmitrii.EmployeeListController.getEmployees(EmployeeListController.java:39)

    org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:842)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

Of course, if I replace the scope tag with compile it'll be work fine. But what's wrong with the usage of the library embedded into the server? Maybe additional configuration needed?

Try adding org.apache.commons.lang in the Dependencies section of your META-INF/MANIFEST.MF file.

I think the problem is that you are not declaring the dependency, so JBoss is not loading the class for you..

Hope it helps!

EDIT: You can set this up through maven using maven-war-plugin or maven-ear-plugin. Here's an example:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>

        <!-- Maven will append the version to the finalName (which is the name 
            given to the generated war, and hence the context root) -->
        <warName>${project.artifactId}</warName>

        <archive>
            <manifestEntries>
                <Dependencies>org.apache.commons.lang</Dependencies>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>
