I'm not sure if I'm doing this right, but since I'm receiving e-mails from this address, I'll try sending a question to it. I am developing server side code that is using JAXP 1.0. The jaxp download from sun includes a DocumentBuilderFactoryImpl class that comes from apache that is in the crimson.jar file. Orion requires the same class and loads the one provided by sun in parser.jar which does not implement the same methods as the one in crimson.jar. I want to use the one in crimson.jar. I cannot figure out how to get Orion to use this one. According to the docs on the DocumentBuilderFactory interface, this can be established via System Properties. I don't know what those are. I have looked at the .properties files in Orion's distribution and I don't see anything that looks like it would specify this. Any help? Thanks
