I recently downloaded a copy of MyEclipse for evaluation.

Has anyone had a problem trying to start WebSphere4 from inside Eclipse for the purpose of stepping through code? I getting a NullPointerException when the application server’s xml configuration file is read. Is there any documentation on this topic? Below is the error message:

This problem looks like an error on your WebSphere domain. Have you tried starting WebSphere outside of MyEclipse to verify that it will run this domain properly?

Other things to check:
Give a look at example configuration for WebSphere4 here: http://www.myeclipseide.com/modules.php?op=modload&name=FAQ&file=index&myfaq=yes&id_cat=20&categories=WebSphere&parent_id=14#14

On the JDK page, did you specify IBM’s JDK for use with WebSphere? You should point to the top-level directory for it (java), not the internal ‘jre’ subdirectory.

I have been successfully running WebSphere outside of the MyEclipse domain.

I have configured the JDK at the top level, and have used the JDK which exists at “websphere\appserver\java”.

My config file is “websphere\appserver\config\plugin-cfg.xml”. It is the only xml file in this directory. Could not find a server-cfg.xml file anywhere.

The contents of this file are:

The problem you’re seeing is caused by specifying a plugin-cfg.xml file where a server-cfg.xml file is expected. That’s why WebSphere is throwing the NPE. In my WAS 4 config directory I have the following files, which were placed there at installation:
admin-server-cfg.xml
plugin-cfg.xml
resource-provider-templates.xml
server-cfg.xml
template-server-cfg.xml

server-cfg.xml is the main server configuration file. Ah, are you perhaps running the AE version of WebSphere 4, rather than the standard edition?

I didn’t actually obtain WebSphere myself. Another person in my group did. They told me it was a trimmed down version.

When I click on “About” on the administrators console, this is what is displayed…

Advanced Edition for MultiPlatforms version 4.0.4

That explains it. The advanced edition has a completely different launch model and we don’t support debugging with it. Of course, IBM doesn’t either, even in WSAD, if I remember correctly.

To debug your application you’ll need the “real” trimmed down version which is plain old WebSphere Application Server v4.0 (or 5.0).

My cohort thinks that he ordered the WebSphere AE version because AEd and AEs didn’t support portal development.

Does anyone know anything about this?

Unfortunately, I don’t have any experience with IBM’s portal products. However, you might try asking on one of IBM’s websphere user groups. Their NNTP server is news.software.ibm.com

I meet the same program.

I find some message at this address.

http://publib.boulder.ibm.com/infocenter/wsphelp/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/rins_portnumber.html

Could you help me,Scott?

Roc,

We only support WebSphere Application Server Advanced Single Server Edition, Version 4.0.x in MyEclipse, which is configured with
a server-cfg.xml file. You’re using WebSphere Application Server Advanced Edition, Version 4.0.x which is configured by a database.
From the link you specified, it might be possible to extract the configuration into a server-cfg.xml file from the database, but I have
no experience in doing that and it isn’t explicitly supported. If you find a method that works, please post it back here as I’m sure it
would prove to be of interest to other users.
