Hello,

I am unable to start the “MyEclipse Tomcat” instance. I receive the following error message from the IDE: “java.lang.NullPointerException: An error has occurred. See error log for more details.”

Upon examination of the .log file, I found the enclosed error. This project was created in the default workspace as a simple web project, with no modifications made to it. I also tried another instance of Tomcat, separate for the sandbox version provided by MyEclipse, and still received the same error message.

Thanks.

Can you go to Windows > Preferences > MyEclipse > Servers > Integrated Sandbox > MyEclipse Tomcat 6 and hit “Restore MyEclipse Tomcat Installation”. Does that resolve the issue?

[tregulski]

No, unfortunately it did not.

I found that, from the Servers tab I can start the server, but cannot “Add Deployment” (no form pops up when I select this option).

I also tried creating a new Web Project, but that did not work either.

[tregulski]

I reinstalled MyEclipse, to no avail. If I try to start MyEclipse Tomcat from Windows | Preferences | MyEclipse Blue Edition | Servers | Integrated Sandbox | MyEclipse Tomcat | Launch, then I get the following error message:

The folder:

exists but is otherwise empty (except for a temp subfolder).

tregulski,
Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Did you setup MyEclipse using the All in One installer?

[tregulski]

Listed below are the Installation Details.

Yes, I installed MyEclipse with All in One.
Thanks.
Tim

I fixed the problem…

I uninstalled JDK 6u12 (which left the latest version being JDK 6u7), which I had heard caused some issues during MyEclipse installation, then uninstalled MyEclipse. I then reinstalled MyEclipse, and can now run “MyEclipse Tomcat”.

Thanks for your help.

I fixed the problem…

Glad you got the issue sorted out. Thanks for letting us know.
