I installed Eclipse and I created the demos/tutorials for webapp and Struts Demo successfully and deployed them to Tomcat 5.0 without any problems. The problem is that when I exit Eclipse and open it again it shows me the folders for both projects, but it is not able to load any resources. When I select the project and do a refresh it shows a popup telling to chech the log file. I get an exception on the .log file

This does sound strange… what happens if you close all edtiros and close the projects, then restart Eclipse and then open the projects? Does that work?

Can you erase the <workspace dir>\configuration directory and restart Eclipse to see if that helps?

[ealfarotx]

I reinstalled Eclipse and recreated the tutorials and now if I close all editors and projects before exiting everything works fine when I restart Eclipse. I even left the HelloWorld project open (webapp) with some file open and everything works, but if I do that with the StrutsDemo project it breaks and I cannot get other projects to load as well. At least I have a solution now where I will make sure to close my projects before exiting Eclipse. It is kind of annoying though and I would not want to lose or break other projects if I forget to do close a Struts project.

[Riyad Kalla]

I agree this is very annoying and I’m not able to reproduce it locally either so I can’t provide walk-through steps for the devs…

We are about to release our 3.8 GA release later this week, if this continues to occur with that please let us know and we can dig deeper into this.
