Re: [eclipse-dev] XML Parsing In an Eclipse 3.0 Plugin
|
Actually, there is a workaround. You can define a jarclassloader that breaks
the usual rule of depth-first class loading and loads your version of xerces
(and anything it uses) from your own jar(s). This is a PITA to get working
properly (the key is to only refer to xerces in classes loaded by the same
jarclassloader), but when it works, it works.
