Couldn't start Ashpool: SAX2 driver class

[sdw]

After running treebeard.bat on Win XP using the sun jdk 1.5.0

I get the following error:

Couldn't start Ashpool: java.sql.SQLException: Could not open datastore: SAX2 dr
iver class org.apache.crimson.parser.XMLReaderImpl not found

Any suggestions? And is the source code for 0.9 downloadable?

Cheers,

I havent tested it with 1.5, It looks like 1.5 doesnt have the crimson xml parser by default - same error on Linux I think.

As for the source you can check it out via cvs, but I havent made a src distro for it yet. Most java IDEs can do cvs check out. Follow these instructions:

http://sourceforge.net/cvs/?group_id=57438

[Rob]

btw

(dir) fangorn/
(dir) appframework_xquery_plugin/

are the two main modules you'll want (fangorn is the main part of the app)

Thanks for the quick reply. How do you set the sax driver Ashpool uses?

[Rob]

Actually your right it's not Treebeard it's self...

http://sourceforge.net/projects/ashpool

cvs: http://sourceforge.net/cvs/?group_id=73642
module: (dir) Tessier/

Off the top of my head, it uses whatever you have setup as the default parser (it's some java system config file) not sure where it is, but all java programs should use it so a quick google should turn something up.

btw a quick way to check ashpool by itsself is

C:\Program Files\Treebeard>java -jar Ashpool.jar .\config

Okay, the isssue does seem to be with ashpool. Looks like it is probably in com.rohanclan.ashpool.core.BasixXslEngine

looks like it hard codes using saxon and the crimson parser.

It'll probably take me a while to get the build environment together (any idea where the crypto package is ?) to test solutions, but I'll post whatever solution I find.

Thanks for the help

Scott

I'll try to fix it tonight if you dont beat me to it - if you just delete all references to the crypto stuff it'll compile fine (the crypto stuff it part of my bread and butter and I should have removed it from cvs) - hard coding :-p I shall beat myself when I get home

[sdw]

okay commented out line 85 in com/rohanclan/ashpool/core/BasixXslEngine.java

System.setProperty("org.xml.sax.driver", SAXDriver);

This allows the system to use its default sax driver. I just replaced the BasicXslEngine class file in the Treebeard Ashpool.jar  and Treebeard starts now.
No idea how this will affect older versions of the jre but WFM :)

Scott

Tried the same solution (recompiling the BasicXSLEngine.java class): received a couple of errors, see below, regarding jimi and avalon which couldn't be resolved (the remaining errors are my own from Windows environment variables in the CLASSPATH) and where it is not clear where you have these jar files from.

Would it not be sensible, if the code has been updated since 2004 to place a new compiled version which does not have the above hard-coding problem in the public domain?
