1. Check the system environment variables from %path%. Is any external java installation path is pointed? If that so, comment and try

2. Check that jasmine.jar(QTP Java loader) in the test environment variable.

Hi, thanks. I figured out what it was, it looks like qtp 10 is incompatible with jre 1.6.35, which was what my local install was at. Or maybe a better way to say it is that, in my setup at least, it is compatible with 1.6.25. When it was working on Monday I had jre 1.6.25. It must have updated on me. I simply uninstalled .35 and reinstalled .25 and I am able to pick up the javawindow class. And hey it only took me a day and a half of hair pulling to figure it out! I guess the good part is that now I know QTP inside and out! lol

Thanks again your comment made me think of the jre version as being an issue.

I don't know! This time without restarting the computer or shutting down, just closing the java app and starting the app again and QTP doesn't see javawindow class. I reinstall java...again. and still can't see it. Restart the computer and reinstall java... Still can't see it. Shut down, power up and reinstall java... Still can't see it.  Something has to be triggered the first time a java app is launched that messes with QTP java hooks... This is ridiculous...

Monday morning, same boat... Does it maybe have something to do with 64 bit windows and QTP10? or a combination of those and jre1.6.25? Tried it on another 32bit windows 7 desktop with the same results.... What really sucks is that I have the entire test coded but can't complete testing since I cant get QTP to see the application anymore, and testing with QTP is required for this project... This is so frustrating! I don't think I will ever take another project that requires QTP.

So another whole day lost... tried a bunch of different versions of java with no working combination. Talked with another guy that says his install is working fine with this java app, he has no java references in his path environment variable. So I remove mine, rebooted but could not get it to work. He said he did nothing special, just had java installed then installed QTP and thats it. So I decided to try a complete fresh install. Removed all java and QTP. On reinstalling I ran into an issue with it hanging on something with the assembly. after some research I found that it was due to a mercury dll that was never removed on the previous uninstall (Not sure if this is a red falg to someone). So I was able to remove that and then ran the QTPCleanUninstallerV2.10 to make sure there were no reminants of the old install. Since I read that they sometimes cause issues. rebooted one more time for fun... Installed java 1.6.0_26, rebooted...then installed QTP 10 with the java optional addin. restarted then brough up qtp then my java app and still only see the java app as the window class. W....T.....F.....

I have to get this working so I will post an update on what doesnt work tomorrow!

The thing I really dont get is why just reinstalling java worked for a few days? Just tried it again and it still wont work. Does anyone have a complete list of what all reg keys, files, windows settings, ect should be in place for java to work? Should the java path be in the path environment variable? earlier on it would not work for me until I put it in manually... I also see people saysing it sould not be there? any suggestions?... At this point I would even consider a format reinstall...

Thinking it may be a windows security update I uninstalled all updates within the past 4 days. Restarted and it made no difference.
