Hello, i am developing a web application. I was using the myeclipse 5.1.0 version and i recently upgraded to the 5.5.1 version. after re-building my project in the 5.5.1 i received two errors in the web.xml file:
1.Referenced file contains errors (file:/C:/Program Files/MyEclipse 5.5.1 GA/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_5.5.1/catalog-xsd/web-app_2_5.xsd). For more information, right click on the message and select “Show Details…”
2.cvc-elt.1: Cannot find the declaration of element ‘web-app’.

after doing a little digging i found that in the same plug-in on the 5.1.0v i did not have a web-app_2_5.xsd file while in the new version it does exist. i then closed the IDE, removed, temporarily, the file from the plug-in directory and re-opened the IDE. after re-building the project the errors disappered.

it seems to me that there must be a better solution to my problem than to manually maipulate a built-in plug-in which comes with the installation. can you please tell me if this is a bug in the IDE or is the code of the web.xml wrong?

web.xml content:

<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.5″

It looks like the problem was with the Java EE 5 JARs that ship with MyEclipse… i would never encourage you to copy around plugins from one release to another (just for future reference, it could lead to squirrely problems).

Given the state of your install, I would actually encourage you, just to start off on the right foot, to grab our 6.0 GA All in One installer and install it to a new dir, then reopen your existing workspace and continue working with that instead.

Also if you ever have build path issues like that again, be sure to first try and restart using -clean as outlined here:
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/

That takes care of 90% of problems usually as they can be caused by stale plugin caches.

Hi Riyad, thanks for your reply.

It looks like the problem was with the Java EE 5 JARs that ship with MyEclipse.

Were you able to reproduce the problem? Can a fix or a more reliable version of the jar be available?

grab our 6.0 GA All in One installer and install it to a new dir

I cannot use this version as we, as a team, work on the same version and we have all upgraded to 5.5.1 we cannot upgrade to the 6.0v

looking forward to your answers. thank you.

I’m not sure why I told you it was a problem with the JARs… looking back over the problem it specifically looks like the web-app_2_5.xsd file was missing from the XML Catalog, which we added a while ago and is used for validation, autocomplete, etc.

If you had to stay on 5.5.1, the first thing I would try (if I were in your position) would be to redownload 5.5.1 All in One installer, and install it to a *brand new* directory (never re-used an existing directory) then reopen your workspace using -clean command line argument and see if all my problems went away.

NOTE: Don’t remove your old install until you are sure the new one is working fine.

NOTE: When you go to create the Start Menu group during the All in One install, you might want to give it a slightly different name, so it doesn’t create shortcuts that just overwrite your existing ones.
