I am using WAS 7 along with ME Blue 7.5. For the past few months I seemed to not have any issues debugging and stepping through code. This week I have been trying to move a service from using HttpClient 3.0.1 to HttpClient 4.0.1 and have noticed something very strange while debugging – about 1/3 of the time after making simple changes while debugging, the debugger had to disconnect due to the change.

When I stopped the debugger and restarted it, my source breakpoints were not aligning at all, as if ME Blue 7.5 was working off of an older copy of the source that was not visible in the IDE. Just now, even after working fine prior to my last shutdown, I restarted a fresh ME Blue 7.5 session and had the issue happen again.

To get around this issue I seem to have to redeploy under ME Blue 7.5 while the debugger is going, then stop the debugger to complete (‘redeploy’) the deployment, then build the EAR and manually Update it in WAS 7 for the problem to go away. But the problem happened way too often today.

Is it some bad historic caching that can be cleared out?

Thanks.

astein70,
Can you give some information?
1. Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Details?
2. Are there any errors logged in the log file located at workspace dir > .metadata > .log?
Also, Can you try using Project > Clean and check if the issue persists?

Clean by itself does nothing to improve debugging, but looking at the .log file I see this after the last clean:

astein70,
Can you switch to a new workspace and check if the issue persists?

[astein70]

Switching to another workspace and coming back in seems to have solved the issue. Is there a way to avoid bouncing workspaces? Some of my co-workers would not have more than one workspace to switch to and use this ‘trick’.

[support-shalini]

astein70,
Good to know that you are all set.
You can create a new workspace if needed and switch to it. Go to File > Switch Workspace > Other. Click Browse in the new window that opens, create a new folder at any desired location and click “OK”.

Is there a way to avoid bouncing workspaces?

I will escalate this issue to the dev team member and they will get back to you on this.

[astein70]

Thank you for the workaround, Shalini.

[support-shalini]

Welcome!!
Do let us know if you have any issues.

[astein70]

The issue continues, errors in the .log file as before. I still (sometimes?) have to run a manual WAS server update with a rebuilt EAR to get debug stepping in line with what the IDE is showing me, and definitely while in the IDE I am stepping through an older set of code somehow. It is as if the ‘redeploy’ from the IDE is not working.

[support-shalini]

astein70,
Sorry for the inconvenience. Can you paste the messages from the deployment log when the redeploy fails?
Right click on your server in the servers view and select “View Deployment Log” from the context menu and check if there are any errors.

[astein70]

I finally got a chance to look at the deployment log, and found that the name it was trying to deploy to did not match the display name in WAS 7, so somewhere in the recent past I must have done something to get ME confused. I rebulit the workspace, renaming projects to what I realy wanted them to be and now deployement/re-deploys do not complain about not finding the application. There is still one issue though. I still seem to have to manually redeploy to get the code in sync once I make a code change; if I do not redeploy from ME then when I run through the code it is stepping through the older version. I have the IDE set to build automatically.

[support-shalini]

astein70,
What is the mode of deployment that you are using? Packaged or Exploded?
When an EAR is deployed in Exploded mode, the changes made to the project are synced to the server immediately.
Please refer to the following for further reference –
http://www.myeclipseide.com/documentation/quickstarts/earprojects/#deployear
Let me know if that helps.
