I am using Eclipse 3.0 version. Everytime i try to start eclipse it asks me to choose the workspace i want to use. I maintain 2 workspace, one for my general applications and the other for my web-application. Everytime i try to open the web-application after i used the general application (I close eclipse after my work and then resart to chosse the other workspace) the workspace is never restored correctly. It always gives me a message check for error logs and below is what i receive from error log
