You're not using Saxon here, you're using the XSLTC processor (part of the
Xalan product). I suspect that's related to the the problem, since calling
conventions for extension functions depend on the processor you are using.
Since file:exists in Java returns a boolean, I would suggest taking out the
" = 'true'" part of the test, since comparing a boolean to a string is
somewhat error-prone.

Subject: [xsl] File:New generates error
Hi,
We have strange error started coming recently for using java
A= PI to check file existence. Recently we moved to saxon and
earlier we were using Xalan but I dont think this caused the
error. We were using this code since years or so without any
problem and this error =A0comes randomly. I am not able to
replicate this in dev environment. I would appreciate your
help on finding root cause of this problem.
XSL Code:
<xsl:template name="file-exists" xmlns:file="java.io.File">
<xsl:param name="filename"/>
<xsl:choose>
<xsl:when
test="file:exists(file:new($filename)) = 'true'">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:template>
Error:
ERROR: 'Cannot convert argument/return type in call to
method 'java.io.File.new(reference)''
FATAL ERROR: 'Could not compile stylesheet'
