Hi,

Try executing the setWLSEnv.cmd file in the DOC prompt and in the same prompt run the command java weblogic.appc

This really isn't a WebLogic question, it is more of a basic Java question. Any time you see a java.lang.NoClassDefFoundError exception you can be sure it is either a Classloader problem (if you are working with J2EE deployments) or a CLASSPATH issue.

In this case the problem is your CLASSPATH is not set correctly. It must include a reference to the weblogic.jar if you want to use WebLogic utilities. A simple solution would look something like this:

  
java -classpath %CLASSPATH%;c:\bea\weblogic700\server\lib\weblogic.jar weblogic.appc My.jar

** Of course, this is assuming that your BEA_HOME is c:\bea.

all the above are not solve the problem

I can guaruntee you one thing: it is a CLASSPATH issue. Do you understand how classloaders work in Java? If so then you should understand the need to have the weblogic.jar (which contains the classes you are trying to use) on either your System CLASSPATH or set in the commandline parameter like in my example above.

Please write back and post your System CLASSPATH and the exact command you are trying to run. Without both of these it is going to be hard to help you any further.

This is my classpath

classpath=D:\j2sdk1.4.2_01\lib\tools.jar;
D:\j2sdkee1.3.1\lib\j2eetools.jar;
D:\j2sdkee1.3.1\lib\j2ee.jar;
d:\bea\weblogic700\server\lib\weblogic.jar;
d:\oracle\ora81\jdbc\lib\classes12.zip;
d:\bea\weblogic700\server\lib\classes12.zip;
d:\bea\weblogic700\server\lib;

Sorry, I just realized what your problem is. Appc was introduced in WebLogic 8.1 and is not available in 7.0. You must have been reading the wrong documentation.

Instead of using appc, you should be using ejbc. The obvious benefit to running ejbc prior to deployment is to identify and correct errors early and often. However, this step is actually entirely optional because WebLogic will automatically run ejbc at deployment time on those EJBs that haven't been precompiled already.
