MyEclipse v6.5 on Windows XP Pro SP3

I’ve been working on a web project for several months. suddenly yesterday evening when i tried to bring up a JSP i received “Error opening the editor”. the details tells me “Error opening the editor. Argument not valid”. what argument? i went to MyEclipse – Preference – MyEclipse Enterprise Workbench – Files and Editors – JSP and everything looked OK to me (i even hit “Restore Defaults” on each page). still i am unable to bring up a JSP in the editor. i tried “Project – Clean”, which was no help. i rebuilt the entire project – again, no help. i imported an old project and tried to view a JSP in it – same error.

help!!!!!!

i’ve uninstalled and re-installed…same problem. all other editors work (java, javascript, xml). there is very little in the registry.

i went to MyEclipse – Perferences – General – Editors and hit “File Associations”. i picked “*.jsp”. i did not see a default. i chose “MyEclipse JSP Editor” and made that default.

all is now well…..

Glad all is well now.
