Problem calling Java method in XSLT (Xalan)

[Robbie Baldock]

Hi -

I'm a bit of a newbie to the world of XSLTs but am trying to call a Java method on a parameter passed into an XSLT but
am having problems.

I've stripped the XSLT down to its bare bones:

<xsl:styleshe et
version="1.0"
xmlns:java="htt p://xml.apache.org/xslt/java"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">
<xsl:param name="requestCo ntext"/>
<xsl:variable name="site" select="java:$r equestContext.g etCurrentSite() "/>
</xsl:stylesheet>

But xsl:variable line produces the error:

"A node test that matches either NCName:* or QName was expected."

Can anyone spot where I'm going wrong?

Thanks for any suggestions.

function names in xslt (as in C or java o most other languages) are
single tokens you can't use an expression to generate the name and you
can't replace part of teh name by a variable reference.

so you can use java:foo(....) if you have a method foo available but you
can't generate a funtion name from a parameter (unless you use an
evaluet() extension function taht parses a string as an Xpath
expression.

/Robbie Baldock/:

<xsl:variable name="site" select="java:$r equestContext.g etCurrentSite() "/>

Did you mean:

<xsl:variable
name="site">jav a:$requestConte xt.getCurrentSi te()</xsl:variable>

or (the same):

<xsl:variable name="site"
select="'java:$ requestContext. getCurrentSite( )'"/>

?

/Robbie Baldock/:

<xsl:param name="requestCo ntext"/>
missed that one...
<xsl:variable name="site" select="java:$r equestContext.g etCurrentSite() "/>

Did you mean:

<xsl:variable name="site">jav a:$requestConte xt.getCurrentSi te()</xsl:variable>

or:

<xsl:variable name="site">jav a:<xsl:value-of
select="$reques tContext"/>.getCurrentSit e()</xsl:variable>

I think it should be the same:

<xsl:variable name="site" select="concat( 'java:', $requestContext ,
'.getCurrentSit e()'"/>

But reading through the David Carlisle's reply I realize you may be
trying something different.

OK, I think I understand...!

Thanks for the info.

hi,

I've stripped the XSLT down to its bare bones:

<xsl:styleshe et
version="1.0"
xmlns:java="htt p://xml.apache.org/xslt/java"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">
<xsl:param name="requestCo ntext"/>
<xsl:variable name="site" select="java:$r equestContext.g etCurrentSite() "/>
</xsl:stylesheet>

you have to use select="java:ge tCurrentSite($r equestContext)"
