Sorry that didn't format correctly. So here the correct format:
I have the following problem:

I have written a test with TestNG in a maven project to test my database. The test runs in the JBoss Embedded Server. The structure of the project:

src 
-main 
-test 
------bootstrap 
----------------lib
----------------resources

And so on.

In the lib-directory are the jars, which are need for the test.

Now the problem: If I want to run the test with the TestNG-Plugin I do the following settings: Classpath-Bootstrap Settings: Adding the jars from the lib-directory. Adding the bootstrap-directory. VMArgs:

 -Dsun.lang.ClassLoader.allowArraySyntax=true 

The test is running perfectly.

But now I want to configurate the test with Maven. In my pom.xml I do the following settings:

<dependency> 
  <groupId>org.testng</groupId>
  <artifactId>testng</artifactId> 
  <version>5.8</version> 
  <scope>test</scope> 
  <classifier>jdk15</classifier> 
  </dependency>

<project> 
[...]
 <build>
   <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-surefire-plugin</artifactId>
         <configuration>
            <additionalClasspathElements>
                <additionalClasspathElement>src/test/bootstrap/lib</additionalClasspathElement> 
            <additionalClasspathElement>src/test/bootstrap/lib</additionalClasspathElement>
             </additionalClasspathElements>
         </configuration>
      </plugin>
   </plugins>
  </build>
    [...] 
</project>

Additionally I have added the bootstrap-folder in the pom.xml Based on the debug outputs the jars are loading in the classpath. But the following error occurs: Unable to bootstrap. If I declare exactly the same jars from my local repository like

<dependency>...</dependency>

Therefore my question: Is there a difference between the testcycle of the TestNG-Plugin and Maven?

Any help is appreciated.

Regards
