[Opensource] DBTool error

[Malcolm Wise]

Hi Mike

I've switched to using the ea4 release as suggested, but essentially I'm
getting the same problem:

Found class org.apache.xerces.jaxp.SAXParserFactoryImpl but unable to
instantiate ClassFactory org.apache.xerces.jaxp.SAXParserFactoryImpl

I've also tried using crimson.jar, but get the same error for
org.apache.crimson.jaxp.SAXParserFactoryImpl.
You're right about some of the reverse-engineering code being commented, so
until that's sorted I guess I'll have to do things manually anyway :-(

Cheers
Malc

Hi Malcom,

Some people reported problems using the Xerces that came with ea-3.  The
new version 2.X series Xerces is now included with ea-4.  You might want to
give it a shot.

I should warn you, however, I was browsing code the other day, and it
looked like somebody (I don't know when or who) commented out the entire
Reverse Engineering section of DBTool, in particular the field type
mappings.  I have no idea if it was because it was buggy or what.  I
haven't had a chance to look into it yet, although it's definitely on my
todo list.

                                         -Mike
