Hi everybody, my eclipse plugin uses "xmlbean" to write into an xml file
in the workspace.

The problem is that I get the following exception with j2sdk1.4.02_05
and not with jre1.5.0_02 !!!!

And a search on gooogle gave no results.. anyone can help me please ?

Hi,

In Java 1.4 the 'built-in' xml parser is Crimson (in 1.5 it has been changed
to Xerces). From the exception I think that you use an xml schema for xml
validation and the Crimson parser does not support schemas.

You can either bundle a Xerces parser with your plugin and use that one for
processing xmls or use a dtd for validation purposes (I prefer the first
one). I do not know xmlbeans so I cannot give more specific advice.

Thanks, that's what I was thinking too...

I'll do the way you say, that means adding the jar, but in case one day
the plugin runs in a 1.5 environment won't there be a conflict between
the default xerces parser and the xerces parser I provide which can also
be of a different version ?

Hi,

I don't use jdk 1.5 so I don't know that the two xerces conflict or not. On
page http://java.sun.com/j2se/1.4.2/docs/guide/standards/ sun specifies a
mechanism to provide newer version of an "endorsed standard library". I have
not tried it but - because sun wrote that 'officially' - it should work
(either specify the directory of xerces jar in the appropriate system
property or create the <java-home>/lib/endorsed directory and place the
xerces jar in it).
