jaxp 1.4 on jre 1.4.2

[Matt Rose]

Dear all,

I am trying to use the jaxp 1.4 standalone download from java.net with
Sun JRE 1.4.2. Here is a minimal test class:

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;

public class TestJaxp {
public static void main(String[] args) throws Exception {
Document doc = DocumentBuilderFactory.newInstance()
.newDocumentBuilder().newDocument();
XPath xpath = XPathFactory.newInstance().newXPath();
xpath.evaluate("/", doc);
}
}

It fails with:

java.lang.NoClassDefFoundError: com/sun/org/apache/xalan/internal/
extensions/ExpressionContext
at
com.sun.org.apache.xpath.internal.jaxp.XPathImpl.eval(XPathImpl.java:
201)
at
com.sun.org.apache.xpath.internal.jaxp.XPathImpl.evaluate(XPathImpl.java:
275)
at
com.sun.org.apache.xpath.internal.jaxp.XPathImpl.evaluate(XPathImpl.java:
365)
at TestJaxp.main(TestJaxp.java:13)
Exception in thread "main"

My classpath consists of this class followed by jaxp-api.jar then jaxp-
ri.jar.

What am I doing wrong?

Thanks,

Matt

Have you read http://java.sun.com/webservices/jaxp/reference/faqs/index.html

I hadn't read that but I don't think it addresses my problem. I tried
fiddling with the settings as described and set it to both explicitly
use the jaxp xerces implementation (which it was doing by default) and
the JRE crimson implementation but received the same error on each
occasion.

The problem goes away if I execute it with a 1.5 JRE.

For the record, this is a bug in the packaging of the 1.4.1 release
that omitted a few classes needed to run on JRE1.4, one of which is
ExpressionContext. The JAXP folks are aware of it and I believe a fix
is likely soon.
