1.) The opening of a struts-config.xml file takes approx. 21 seconds and the ui is frozen. Looks like too much is being done in the ui thread.
Are you behind a firewall? If you take the URL for the DTD used by the Struts file and paste it into a web browser, does it load immediately? If you go into MyEclipse XML Editor settings, and turn off “use cache” and turn on the ability for it to download missing DTDs, does the problem go away?
2.) If I have a struts-config.xml file open in the struts editor and this editor is the current one in the editor area, then when I restart eclipse the Package Explorer view fails to be created.
This was reported, and I believe the fix is targetted for Beta2.
