Xalan-JavaScript extensions - unable to load language?
Hello All,
I tried to make use of lxslt:component and lxslt:script from attached
examples (xalan-j/extensions.html - last example), but got error
message:
Xalan-j 1.2.2:
----------------------------------------------------------------

========= Parsing file:D:/xsl/doc.xml ==========

XSLT Error (javax.xml.transform.TransformerException): Could not compile
extension
-------------------------------------------------------------------------------
Why???
In both cases CLASSPATH had bsf.jar; xalan.jar; xerces.jar of the
appropriate version.
In early versions of Xalan it(extensions) worked.
Thanks in advance for any help you can provide!

Hi Sergey --
Please make sure that you have the correct version (1.5) of js.jar
(downloadable from http://www.mozilla.org/rhino) in your classpath.
This is a different version of js.jar than was used in earlier releases
of XalanJ. However, this is the version that is required for the
version of bsf.jar packaged with later XalanJ releases.
See http://xml.apache.org/xalan-j/extensions.html#supported-lang
HTH,
Gary
