Head First EJB - Chapter 1 Application

[Cliff DeRose]

Hey all,

I have been trying to find out why I keep getting this error. I've read a few posts on this board, and searched google to no avail so maybe someone can help.

I followed the instructions in Chapter 1 exactly. I have version 1.3.1 of the J2EE sdk/RI server (as the book requires). I was able to deploy everything successfully. When I tried to run the client application, it blew up and gave me the following error. Am I missing something in the classpath perhaps?

%CLASSPATH% = C:\j2sdkee1.3.1\lib\j2ee.jar
Both the AdviceClient.class and AdviceAppClient.jar are in the current directory

Looking at the first line of the error, where can I find the
com.sun.corba.se.internal.util.JDKBridge class?

C:\Projects\advice>java -cp .;%CLASSPATH%;AdviceAppClient.jar AdviceClient

Any help would be appreciated.

Hi there,

Make sure that you include appserv-rt.jar in the class path for the client application. This jar contains the jndi.properties file which contains all bootstrapping properties for the Application servers naming services.

Thanks

Thanks for the response. That didn't fix my problem, however, I did find the root cause of the problem. The class (JDKBridge) that wasn't being found can be found in:

C:\j2sdk1.4.2_08\jre\lib\rt.jar

After adding that to my classpath, the program worked fine.

Sir,

I used the same approach. But, I am getting a new error. Please reply.

Hi Shouvanik,
The post that you have replied to is more than 8 years old. I don't think the problem faced then would be the same and I don't think you are using the same version of the software. I would suggest to you create a new topic with more details.
