Hello,
I'm a newbie to XEP and (truthfully) to Java, so please bear with me if
these are stupid questions...
I'm using the trial version 3.2.1 and have created a relatively simple
XSL-FO stylesheet to processes my XML document. All is going well, I'm able
to get a PDF generated and am starting to make formatting changes. One of
the changes requires trying to use an embedded Javascript function to do
some more complicated checking of the DOM. I've searched for examples on
the web where this is done, and I believe I'm doing everything correctly,
but I get an error message when I try to build the PDF, I get the following
error:
"The URI http://www.doejs.com/ does not identify an external Java class"
Of course, I just made up this namespace, but the examples I've seen seem to
do the same thing -- again, I'm not a Java guy so I may be doing something
really obviously wrong.
Without sending a whole lot of code,
Here's a test XSL that demonstrates the error... The error only occurs when
I actually try to call the javascript function (if I comment out the call,
the PDF is generated fine):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:lxslt="http://xml.apache.org/xslt"
xmlns:doejs="http://www.doejs.com/"
extension-element-prefixes="doejs"
version="1.0">
<lxslt:component prefix="doejs" functions="getResult">
<lxslt:script lang="javascript">
function getResult() {
return '123';
}
</lxslt:script>
</lxslt:component>
<xsl:template match="intro-chapter">
<fo:block font-size="20pt">
<xsl:value-of select="doejs:getResult()"/>
<xsl:value-of select="456"/>
</fo:block>
</xsl:template>
</xsl:stylesheet>
*************************************
Also, because I don't know any better, here's the command line I'm using to
build the PDF. I've seen reference to making sure the BSF.jar and JS.jar
files are in the classpath, but am not sure I've done this correctly.
java -classpath "C:\Program Files\XEP\lib\xep321_trial.jar;C:\Program
Files\XEP\lib\cryptix32.jar;C:\Program
Files\XEP\lib\cryptix32-pgp.jar;C:\Program
Files\XEP\lib\saxon.jar;C:\Program Files\XEP\lib\xt.jar;C:\Program
Files\XEP\lib\bsf.jar;C:\Program Files\XEP\lib\js.jar;"
com.renderx.xep.JAXPDriver -Dcom.renderx.xep.ROOT="C:\Program Files\XEP"
-xml "c:\cgpubsys\guides\test\xml\hmd.xml" -xsl "c:\program
files\softquad\xmetal 3\fop\cgstandard01_fo.xsl" -out testx.pdf
Most of the classpath is taken directly out of the transform.bat file, with
the paths to BSF and JS tacked on at the end. I realize that if XEP is
adopted here, I'll have to become much more versed in Java, but this is just
supposed to be a proof-of-concept effort and any help would be greatly
appreciated.
