I've upgraded my Eclipse Helios with Tomcat 5.5 to Eclipse Indigo. Now every time I modify any file in project (JSP, JS), Tomcat republishes the changes, redeploying the complete application (this didn't happen before, JSP changes were available immediately, without republishing).
When republishing, I get publishing errors every time
Could not delete X:/work/ws-trunk/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/myApp/WEB-INF/lib. May be locked by another process.
