Description davybeans 2009-11-24 07:25:44 UTC 
Hi,

I have followed all steps as outlined in the following article and have taken all the default install options during configuration.

http://developers.sun.com/webtier/reference/techart/deploy_nb.html

However, when I right-click on my web project and select Debug, I get the stack trace below.  I can attach a debugger by selecting "Debug\Attache Debugger" from the top menu but this does not enable the HTTP Server Monitor or JSP/JS debugging.

Thanks
Dave

Is this a problem with the deployment infrastructure or with the webserver plugin?

Hi,

I've only got back to this now.  I would guess the problem is with the deployment infastructure because I can debug by selecting "Debug\Attache Debugger" from the main menu in Netbeans.

Is this what you mean?

Incidentally I've tried this in SJSWS 7 update 8 running on NetBeans 6.9.1 and I still get the same problem.

Thanks
David
