Error in Eclipse 2.1.2

[Kevin M]

I wasn't able to get the Eclipse plugin working for Eclipse 2.1.2. As soon as I try to open an XML document, such as web.xml, I receive the following errors:

Error - Unable to create part: web.xml
Error - An error has occurred when activating this view
An error has occurred when creating this editor

I installed it properly by unpackaging the plugin into the Eclipse plugins directory. I was also able to successfully paste in my trial license. Any ideas why this isn't working?

Can you give us more details (platform, Java version - look in Help -> About -> Configuration details -> java.version, stack trace in the error log - look in the file workspace/.metadata/.log) ?

[kmacclay]

Sure, here are some more details. Perhaps this is an issue with using the beta of JDK 1.5 (I forgot I had this set up)?

It seems indeed a JDK 1.5 related problem. Can you try with Java 1.4.2 ?

Best Regards,

I changed to JDK 1.4.2 and it works. Thanks for your help. It looks like a useful plugin so far.
