How can I tell my application that it shouldn't use an external Service Provider from a jar?

Question

For some reason we need the xdb.jar from the Oracle XDK. This jar depends on the xmlparserv2.jar. The actual problem is that the xmlparserv2.jar comes with some provider-configuration files (META-INF/services). The jar has Services Providers for javax.xml.transform.TransformerFactory, javax.xml.parsers.SAXParserFactory and javax.xml.parsers.DocumentBuilderFactory. The implementations (from oracle.*) don't work together with some other parts of our software (they need the standard factories).

Answer 1

I solved the problem by removing the services (META-INF/services). We ran our unit tests and everything worked. Even the parts of our software which are depending on xmlparserv2.jar/xdb.jar.

Answer 2

You could just remove these classes from the xmlparserv2.jar

Answer 3

See here - "JNLP classpath precedence 1.5 vs 1.6"

Answer 4

You could use separate classloaders to isolate the jars from the rest of the application. This question about covers it.
