Weblogic optional package deployment issue

Question

Hi All,
I am using WLS 10.3.4. I have an J2EE web application which references a JAR library as an optional package. Here is my definition of JAR file in the library MANIFEST.MF,
Manifest-Version: 1.0
Extension-Name: PCGCommon2.0
Specification-Version: 1.0.0.0
Implementation-Version: common055jkp
Here is my definition of JAR file reference in the application MANIFEST.MF,
Manifest-Version: 1.0
Extension-List: pcgcommon2
pcgcommon2-Extension-Name: PCGCommon2.0
pcgcommon2-Specification-Version: 1.0.0.0
pcgcommon2-Implementation-Version: common055jkp
I deployed the JAR library first successfully. Then I tried to deploy the application. It throws me this error as follows,
+[J2EE:160149]Error while processing library references. Unresolved Optional Package references (in META-INF/MANIFEST.MF): [Extension-Name: PCGCommon2.0, Specification-Version: 1, Implementation-Version: common055jkp , referenced from: /opt/oracle/Oracle/Middleware/user_projects/domains/Pinellas1qDomain/servers/Pinellas1qMS3/tmp/_WL_user/ppa/cwbd0p/war].+
Can anyone have an idea what I am missing here?
Thanks in advance,
-John

Hi John,
Please find the working TestCase in the following Location:
http://middlewaremagic.com/weblogic/?p=231#comment-3144
I am copying and pasting the README.txt file here which i attached in the TestCase:
README.txt
Step1). Make Sure that the Hello.java is compiled properly like following:
javac -d . Hello.java<font color=red>Actual Trick is Making the JAR using 'M' option..... :) </font><br>
Step2). The Most important step to Make the "HelloWorld.jar" along with the MANIFEST.MF file which is present inside "HelloWorld\META-INF\MANIFEST.MF"
Use the below command with *'M'* as a Flag while making JAR file so that the Jar utility will not overrite the MANIFEST.MF on it's own rather it will place our own MANIFEST.MF inside the Jar.
C:\OptionalPackageDemo\HelloWorld\> jar -cvfM  HelloWorld.jar META-INF\MANIFEST.MF Hello.java com
Step3). Deploy the HelloWorld.jar and the TestWebApp
<b><font color=red>NOTE: </font></b> I just now tested the attached TestCase in WLS10.3.0 And it perfectly worked for me. So if it's not working for you in WLS10.3.4 then i would request you to please open a Support Ticket with Oracle WebLogic Support Team because ideally the same test case is supposed to work fine in that version as well.
Thanks
