Please Set Up Java EE classpath in the properties dialog

Within a "Mainframe COBOL Project," I'm trying to generate a Java client for a COBOL program. To do this, I'm using the context menu option on the COBOL program: New -> Java Interface. This has created the "Java Interfaces" path within the project, and inside that path, a file with the .xml extension containing the mapping between the Java attributes and the COBOL Linkage structure.

So far, so good, but when I run the "Generate Client" option from the context menu of the .xml file, the following error message appears: "Please Set Up Java EE classpath in the properties dialog." I've been investigating, and it seems the problem is that it can't find the mfccl.jar Java library, but I don't know where I need to declare it to avoid the error and generate the Java client.

Thanks.

Hi Sergi,

Can you advise, are you looking to create a CICS Web Service, I’d like to understand the goal of using a Mainframe COBOL project and Java Client.

Regards,
Kim

I work with a Java SE client application that makes remote calls to the Rocket enterprise server back end for COBOL programs using the ECI protocol, an IBM CTG and IBM libraries on the client side. The goal of the PoC is to make a remote call to the Rocket enterprise server back end for a COBOL program but using Rocket client libraries and without the IBM CTG.

Thanks Sergi,
Going back to: "Generate Client" option from the context menu of the .xml file, the following error message appears: "Please Set Up Java EE classpath in the properties dialog." I've been investigating, and it seems the problem is that it can't find the mfccl.jar Java library, but I don't know where I need to declare it to avoid the error and generate the Java client.

I find the file mfccl.jar in path  C:\Program Files (x86)\Micro Focus\Enterprise Developer\javaee-ccl\common on my machine, can you share screenshots of what your "Generate Client" looks like, to see if there is a way to add library/jar references?

I have tried declaring the jar mfccl.jar in both the Windows PATH and CLASSPATH environment variables but this hasn't fixed the error. Also, in the 'Run-time Configuration -> Environment Variable' section of the project's context menu, I declared the CLASSPATH environment variable inside the Rocket Enterprise server and that hasn't solved the problem either. That's why I just opened a case with Rocket.

Thanks, I was going to propose a support case, thanks for raising that.
