It is.

I tried that with no success. Here's a more explicit description of what I'm
doing:
CLASSPATH:
.;F:/jdk1.3/lib/tools.jar;F:/jakarta-tomcat-3.2/lib/servlet.jar;F:/xalan-j_2_0_D
01/bin/xerces.jar;F:/xalan-j_2_0_D01/bin/xalan.jar;
I've tried many different variations of CLASSPATH; the one listed above is
the latest.
XslProcessorBean, which is called from a JSP custom tag, is listed below:
package beans.xsl;
import java.io.*;
import java.net.URL;
import javax.servlet.*;
import javax.servlet.http.*;
import org.xml.sax.InputSource;
import org.apache.trax.*;
public class XslProcessorBean implements Serializable {
public XslProcessorBean() {}
public void process(InputStream xmlstream,
InputStream xslstream,
HttpServletRequest req,
HttpServletResponse res)
throws IOException, ServletException {
Processor processor = createProcessor();
InputSource xmlSource = new InputSource(xmlstream),
xslSource = new InputSource(xslstream);
if(xmlSource != null && xslSource != null) {
try {
Templates templates = processor.process(xslSource);
Transformer transformer = templates.newTransformer();
transformer.transform(xmlSource, new Result(res.getWriter()));
}
catch(Exception ex) {
throw new ServletException(ex);
}
}
}
private Processor createProcessor() throws ServletException {
Processor processor = null;
try {
processor = Processor.newInstance("xslt");
}
catch(Exception ex) {
throw new ServletException(ex);
}
return processor;
}
}
This line (line 27; see below) results in the exception:
transformer.transform(xmlSource, new Result(res.getWriter()));
And here's the exception:
Location: /xslt/test.jsp
