I think what I’m looking for here something along the lines of suggestions rather than reporting a bug… Here’s the deal… I have project that is built with an Ant script. The project is *huge*. It’s got multiple EAR/WAR files. They all deploy into WLS 8.1. I typically run 8.1 within jboss and then deploy the files via the web interface. Occassionaly, when I go to update and file and the hotdeploy it I’ll get the ‘unable to hotdeploy’ dialog. Which pretty much leaves me unable to debug, make changes, etc..

I really don’t want to try to re-make the ant targets as EAR/WAR targets in the project itself, but I still need hotdeploy.

Any suggestions?

DaveO,
Can you describe how you “update the file and hotdeploy it”, is this all from the web interface?

[David Orriss Jr]

You’re right.. that was unclear. First, I run WLS 8 within MyEclipse. I run an ANT build within MyEclipse on the project. I upload these newly Ant-build objects via the WLS 8.1 interface. Then I make changes to source files and re-build/re-compile then in MyEclipse. About half the time, the hot-deploy on these new-compiled objects will fail. It’s pretty consistent tho. Take two classes – ClassA and ClassB…. ClassA will always hot-deploy, while ClassB never will.

Does this help?

Dave,

There’s a detailed thread on this type of behavior with WebLogic here:
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-955-highlight-hot+deployment+jpda.html

And, a general discussion on the limits of JPDA here:
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-439-highlight-hot+deployment+jpda.html

Do those help explain what your seeing?

Hi Scott,

Sadly, yes… those explain it PERFECTLY… *sigh*.. well, I’m not going to bunch up over it too much.. I’m changing employers and going to a new company starting on Thursday. I’ll deal with this kinda stuff over there and call it ‘lesson learned’ for now…

Thanks for the information… This mesage is *exactly* what I’m seeing:

org.jboss.Main at localhost:6164 (may be out of synch) was unable to
replace the running code with the code in the workspace.

Reason: Hot code replace failed – Scheme change not implemented.

Thanks again for the links.

Scott,

One other thing however… the above message occurs even when I don’t change the ‘shape’ of the class. But I think you’ve hit the nail on the head, regardless.
