Access restriction on class due to restriction on required library rt.jar?

I’m attempting to compile Java 1.4 code that was created by IBM’s WSDL2Java on Java5 without recreating the stubs and saw this error in Eclipse.
I’m under the assumption that the stubs generated should just compile as long as the runtime jars are available (they are).

Access restriction: The type QName is not accessible due to restriction on required library C:Program FilesJavajdk1.5.0_16jrelibrt.jar

The full class name is javax.xml.namespace.QName

What exactly is going on here? Is this a case where I am trying to refactor a pig from sausage? Am I better off recreating the stubs?

There’s another solution that also works.

1. Go to the Build Path settings in the project properties.
2. Remove the JRE System Library
3. Add it back; Select “Add Library” and select the JRE System Library. The default worked for me.

This works because you have multiple classes in different jar files. Removing and re-adding the JRE lib will make the right classes be first. If you want a fundamental solution make sure you exclude the jar files with the same classes.

For me I have: javax.xml.soap.SOAPPart in three different jars: axis-saaj-1.4.jar, saaj-api-1.3.jar and the rt.jar
