Using Sun Java Studio Creator , and executing an application, how could HTTP Status 500 error occur when the server is up and running ???
The bundled application server is still running, so what's wrong?
Well, here's a couple of reasons
1) Database or SQL syntax error
2) Null pointer exception in your application.
To find out exactly what went wrong, check the bunder Server log file
Open Servers window, select the Deployment Server node , right-click and
choose Server log
hope this helps
Update: To retrieve the server log file for Visual WebPack and NetBeans, click on the Runtime tab, select Tomcat, Sun Java System Application Server or JBoss and choose View Server Log. The server log file will appear in the Output window. In the Output window, type Ctrl-A to select all then Ctrl-C to copy. Then the contents can be pasted in an editor or email
