In my computer, when I use Helios to open a JEE project(Left click a JEE project folder in the Project Explore Perspective) I have to wait almost 3 minutes to open it. It seems that Helios have to download something from Internet to do some Validation. When I disconnect the Internet,the activity is faster. Maybe my network is too bad. I think it is about the web.xml file. When I delete the web.xml file this can be fast.If there is a way to solve this problem ?Or just use another version of eclipse instead of Helios.My English is not good, if there is anything not clearly, my apologise

The JEE component adds a lot of web-related stuff that is not part of
JDT. In particular, there are schema validators, that need to go out to
the web to fetch .xsd files to validate XML schema.

In theory I think these files are supposed to be cached locally after
they have been fetched, but I don't know much about that.

You might want to repost this to eclipse.webtools, which is the
newsgroup best suited for discussion of the JEE component. They'll
probably have some more concrete troubleshooting suggestions.

Thank you, I'll do it.
