Suman MukherjeeParticipantHi,
I am getting an error while opening web.xml file for a newly created web project.
I am using MyEclipse 7.5. The error stacktrace is given below :java.lang.ClassCastException: org.jboss.tools.common.xml.XMLEntityResolverImpl cannot be cast to org.apache.xerces.xni.parser.XMLEntityResolver

support-joyMemberSuman,
Sorry to hear you are running into this issue. Can you answer few queries for me?
1. Can you copy and paste your installation details. Open MyEclipseIDE from menu options click on MyEclipse > Installation Summary > Installation Details.
2. What is the editor you have used to open the web.xml?
3. Can you refresh your project.
4. Use -clean command line argument to open your IDE? Please refer – https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/
5. Can you attach screenshots which will help me get a visual.
6. Do you have any project references to this newly created web project?
Suman MukherjeeParticipantthanks it works after myeclipse.exe -clean.
Suman
support-joyMemberGood to hear you are all set.
