Master documentation around jar

Question

Is there a master document out there that contains a map of what .class files are in what .jar files that are in the Netweaver Developer Studio/JDT plugins folder?
I am having a difficult time resolving NoClassDefFoundError exceptions in my code. It would be helpful to know what .jar files to include as part of my project build path BEFORE runtime.
This code segment:
Connection conn = null;
Context ctx = null;
try
ctx = new InitialContext(env);
Object obj = (Object)ctx.lookup("jdbc/SAPJ2EDB");
yields the following exception:
=====================
com.sap.engine.services.jndi.persistent.exceptions.NamingException: Exception during lookup operation of object with name jdbc/SAPJ2EDB, cannot resolve object reference. [Root exception is com.sap.engine.services.connector.exceptions.BaseResourceException: Cannot lookup ManageConnectionFactory "SAPJ2EDB". Cannot deserialize object: java.lang.NoClassDefFoundError: javax/resource/spi/ResourceAdapter.
=====================
My questions are:
1) Am I looking up the datasource correctly?
2) What .jar file contains the ResourceAdapter.class file? NoClassDefFoundError exceptions make me nervous.
Thanks in Advance,
JC

Answer 1

Hi Jason, Narinder,
Actually, sapjra.rar is not the right answer to the 2nd question. javax.resource.spi.ResourceAdapter is part of the standard J2EE connector architecture and is contained in connector.jar (...\plugins\com.sap.tc.ap\comp\SAP-JEE\DCs\sap.com\j2eeca\_comp\gen\default\public\default\lib\java). As for the 1st question - yes, you're doing the lookup correctly.

Well, the minimum required are sapj2eeclient.jar, exception.jar, and logging.jar. Further libs may be required depending on what you're trying to do in your project. E.g. in your case you'd also need at least jdbc20.jar and connector.jar.
Hope that helps!
