SaxParser error while using WSIF bindings in BPEL

Question

Hi All,
I am using WSIF bindings in BPEL to invoke a java class.
This java classs is using Jersey Client. For this I have imported relevant jersey jar files version 1.1.4.1.
My java class is getting invoked and even the jersey client jars are also recognized by my project.
But I am getiing the following SAX parser error:
*Operation failed!; nested exception is: javax.ws.rs.WebApplicationException: javax.xml.bind.JAXBException: Error creating SAXSource - with linked exception: [org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.]*
I found the following details when checked the logs.
JAXP feature XMLConstants.FEATURE_SECURE_PROCESSING cannot be set on a SAXParserFactory. External general entity processing is disbaled but other potential securty related features will not be enabled.
Please let me know what should be done in order to solve this issue.
Thanks in advance!!!

I am having the same problem in a non-BPEL application. I am using Oracle MDS in an application that is also using Jersey 1.1.4.1 and it blows up Jersey 1.1.4.1 in the same way.
Oracle MDS has a dependency on Oracle XDK, an XML parser (xmlparserv2.jar). xmlparserv2.jar registers Oracle's oracle.xml.jaxp.JXSAXParserFactory using the Java ServiceLoader API (by using the file META-INF/javax.xml.parsers.SAXParserFactory.
Jersey doesn't like Oracle's JXSAXParserFactory, as you can see. From what I've found so far, it seems that the Oracle SAXParserFactory is clamped down for security and Jersey will not work with it. Here is a more complete stack trace that I have:
[org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.]

Caused by: org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.

at oracle.xml.jaxp.JXSAXParserFactory.newSAXParser(JXSAXParserFactory.java:92)
at com.sun.jersey.core.provider.jaxb.AbstractJAXBProvider.getSAXSource(AbstractJAXBProvider.java:174)
In my case, Jersey seems to ignore the system property that I set with -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
I am trying to figure out a way to satisfy the dependency that my app has on Oracle's XDK (xmlparserv2.jar) without having its SAXParserFactory take over Jersey.
I'll try to post here if I ever solve my problem because it sounds the same as yours.
