JRockit vs HotSpot类加载问题-META-INF / services

Question

According to the javadoc of javax.xml.validation.SchemaFactory#newInstance, I can specify which implementation of SchemaFactory I want, by placing a file in META-INF/services called javax.xml.validation.SchemaFactory with the required class (in my case org.apache.xerces.jaxp.validation.XMLSchemaFactory).

This works fine when I run Weblogic using the HotSpot JVM, but when using the JRockit JVM, it doesn't find anything in the META-INF/services directory (I've stepped through the code on the server and in javax.xml.validation.SchemaFactoryFinder#createServiceFileIterator, the Enumeration returns empty for JRockit but the correct resouce for HotSpot). I think it might be because it is using a different classloader.

Any suggestions?

Answer 1

最后，我通过在weblogic启动脚本中设置-Djavax.xml.validation.SchemaFactory = org.apache.xerces.jaxp.validation.XMLSchemaFactory来解决此问题。
