Adding External Jars in Module development

Question

Dear Friends,
                        Actually i am adding an external Jar file in my EJB Module in NWDS.I am using this jar file for converting XML to flat file and i am calling this module from Receiver ommunication channel.For this process, i am importing dom4j.jar file in the EJB Module.I have created a jar file for that module,
                      Now i have created an external Library project for the cause that i have used the external jar file, and i have made following code in the provider.xml file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE provider-descriptor SYSTEM "library.provider.dtd">
<provider-descriptor>
     <display-name>
      XML2EDI_Library
    </display-name>
     <component-name>
      XML2EDI_Library
    </component-name>
     <major-version>6</major-version>
     <minor-version>40</minor-version>
     <micro-version>0</micro-version>
     <provider-name>
      dom4j.org
    </provider-name>
     <references>
          <reference
               provider-name="dom4j.org"
               strength="weak"
               type="library">org.dom4j.Document</reference>
          <reference
               provider-name="dom4j.org"
               strength="weak"
               type="library">org.dom4j.DocumentException</reference>
          <reference
               provider-name="dom4j.org"
               strength="weak"
               type="library">org.dom4j.Element</reference>
          <reference
               provider-name="dom4j.org"
               strength="weak"
               type="library">org.dom4j.io.SAXReader</reference>
     </references>
     <jars>
          <jar-name>EDI_Module.jar</jar-name>
     </jars>
</provider-descriptor>
I have included 4 references because i have imported following in my ejb module.
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
I am not sure of wht to include in reference target and provider name, I am getting the following exceptions in Message monitoring:
1. AO: Document Exception: org.dom4j.DocumentException: E:\usr\sap\BWS\DVEBMGS00\j2ee\cluster\server0\
2. Nested exception: E:\usr\sap\BWS\DVEBMGS00\j2ee\cluster\server0\
Help me in this issue..
Thanks in advance

Dear Stefan,
                    I will explain my problem here..in brief
1. I have created an EJB Module and adding an external jar dom4j.jar
2. I have the my jndi name as XmltoText
3. In my application-j2ee-engine.xml in my EAR file...i have included :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE application-j2ee-engine SYSTEM "application-j2ee-engine.dtd">
<application-j2ee-engine>
<reference
     reference-type="weak">
     <reference-target
       provider-name="dom4j.org"
       target-type="application">TEST_LIBRARY
      </reference- target>
</reference>     
<fail-over-enable mode="disable"/>
</application-j2ee-engine>
           TEXT_LIBRARY is name of my Library Project.Please tell me corrections in the above code...i have doubt regarding provider name.
4. As i have added external jar file in my ejb module..._i have created a Library project and in that project in provider.xml_ file i have included the following code...
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE provider-descriptor SYSTEM "library.provider.dtd">
<provider-descriptor>
     <display-name>TEXT_LIBRARY</display-name>
     <component-name>TEXT_LIBRARY</component-name>
     <major-version>6</major-version>
     <minor-version>40</minor-version>
     <micro-version>0</micro-version>
     <provider-name>****</provider-name>
<references>
<reference
     provider-name="****"
     strength="weak"
     type="library">****</reference>
</references>
<jars>
         <jar-name>EJBModule.jar</jar-name> (This is my EJB Module jar file)
</jars>
</provider-descriptor>
Now what should i include in the places of **** in the references above??
Thanks and Regards,
