Question

I am upgrading my environment from eclipse 3.3.1 and java 1.4 to eclipse 3.4.1 and java 1.5. My unit tests are in jUnit 3.

eclipse java version 1.5.0__17

stand alone env version 1.5.0__12, or 1.5.0-17, both work.

I have a method on a class that writes an XML file to disk. It calls TransformerFactory tf = [javax.xml.transform.]TransformerFactory.newInstance(); When I run the code outside of eclipse it runs fine. When I run the code in jUnit in eclipse I get the stack trace below. The missing class is in the rt.jar of java 1.4 and not in java 5, but shouldn’t that be abstracted from me?

How can I make the test pass?

I get the same error when I run the code in eclipse from an application.

update I did some more research in the bowels of the stack trace. The working versions (outside eclipse) are returning an instance of com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl which is the fallback impl class name in javax.xml.transform.TransformerFactory.newInstance()

     public static TransformerFactory newInstance()         throws TransformerFactoryConfigurationError {         try {             return (TransformerFactory) FactoryFinder.find(             /* The default property name according to the JAXP spec */             'javax.xml.transform.TransformerFactory',             /* The fallback implementation class name, XSLTC */             'com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl');         } catch (FactoryFinder.ConfigurationError e) {             throw new TransformerFactoryConfigurationError(                 e.getException(),                 e.getMessage());         }     } 

Answer 1

I added the following line to setup of the unittest

    System.setProperty('javax.xml.transform.TransformerFactory', 'com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl'); 

I figured out what to do with a bit of RTFM. http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/transform/TransformerFactory.html#newInstance()
