I am seeing the following error when trying to "Run As -> My Eclipse Server Application -> Tomcat 6.x":
--

I have configured the Tomcat 6 instance in the Window->Preferences settings. I am able to build the war and run it on that Tomcat instance outside of Eclipse. Note: I am using Perforce with the P4WSAD plugin, so maybe there is a read-only file somewhere that MyEclipse isn't able to update? Also, I am running MyEclipse 6.5 on Mac, installed by installing Eclipse 3.3 classic and then using the MyEclipse archive update site zip file. |

pfishero,
Can you start the Tomcat server without issues from the server view? Maybe the P4WSAD is causing the issue here. Can you try Run As -> My Eclipse Server Application -> Tomcat 6.x without the P4WSAD plugin setup. Does it work? |

I am able to start the Tomcat server from the Servers pane. However, after doing that when I try to run my project on that server (via Run As -> My Ecliipse Server Application -> Tomcat 6) it still produces the same error.
I will try uninstalling the P4WSAD plugin, but in case that doesn't work, do you have any other tips or suggestions?
Thanks! |

Are you able to run your app against the MyEclipse Tomcat server(Run As -> My Ecliipse Server Application -> MyEclipse Tomcat Server)? This is also a Tomcat 6 server. Incase you app works against the MyEclipse Tomcat server then something is definitely messed up with the Tomcat 6 server your using.
Let me know what result you get after uninstalling the pulgin. |
