I’m trying to see if MyEclipse will work for us as we are using multiple application servers here and would like to use a single IDE. At the moment I am trying to configure the connector for WebSphere 4.0 Advanced Single Server edition and am having problems. I’ve been able to successfully deploy my application to the server, but when I choose Server->WebSphere 4->Start, I get the following error:
java.lang.NoClassDefFoundError: com/ibm/crypto/provider/IBMJCE
This is followed by a dialog box that says “Could not find main class, program will exit”. What am I missing in this configuration?

I’d like to modify my earlier statement and say the the application is not being deployed successfully. I do see the files are getting deployed, but when I bring up the application server external to myeclipse, it doesn’t see them.

Todd,
WebSphere’s deployment model is a bit odd. It doesn’t have an “autodeploy” concept like all the other application servers, so the only way to deploy seems to be by manually deploying through its console. Also, manual deployment only accepts an archive file (EAR), not an exploded equivalent. When the app is deployed, however, it is saved in the standard exploded format and it will pick up changes to modified components. Given all this, here’s what needs to happen for WebSphere deployment.
1) You will need to do a one-time deploy as an EAR which will place the archive into WebSphere’s installableApps directory.
2) You must then use WebSphere’s console to deploy the application.
3) Once installed, you can then set up an exploded deployment on top of the one that WebSphere created in the ‘installedApps’ directory.
4) At this point, Sync-On-Demand will handle keeping your WebSphere deployment in sync with your workspace as you make modifications.You’ll also need to make sure that you start WebSphere with only the JDK that is shipped with it by adding it to the Windows > Preferences > MyEclipse > Application Servers > Websphere 4 > JDK page.
