Subject ESQL throws XSLProcessorException
Date Wed, 25 Apr 2001 00:36:40 GMT
I can't get ESQL running on Cocoon 1.8.2: This seems like a wierd XSL
problem where variables and parameters declared in the top level cannot be
accessed therein. Has anyone at all seen this? It seems like plenty of
people have gotten ESQL running on Cocoon 1.8.2, but I just can't seem to
get it going! :( Oh, this is running on Weblogic 6 BTW, in case that makes
any difference.
Thanks a mill in advance,
Navneet

OK, so I sat and looked at the source of the ESQL.xsl file (the main ESQL
processor and put this in a new stylesheet:
<xsl:param name="XSP-ENVIRONMENT"/>
<xsl:param name="XSP-VERSION"/>
<xsl:param name="filename"/>
<xsl:param name="language"/>

<xsl:variable name="cocoon1-environment">Cocoon 1</xsl:variable>
<xsl:variable name="cocoon2-environment">Cocoon 2</xsl:variable>

<xsl:variable
name="cocoon1-xsp-namespace-uri">http://www.apache.org/1999/XSP/Core</xsl:va
riable>
<xsl:variable
name="cocoon2-xsp-namespace-uri">http://apache.org/xsp</xsl:variable>

<xsl:variable name="environment">
  <xsl:choose>
    <xsl:when test="starts-with($XSP-ENVIRONMENT,$cocoon1-environment)">
      <xsl:text>cocoon1</xsl:text>
    </xsl:when>
    <xsl:when test="starts-with($XSP-ENVIRONMENT,$cocoon2-environment)">
      <xsl:text>cocoon2</xsl:text>
    </xsl:when>
    <xsl:otherwise>
      <xsl:text>cocoon2</xsl:text>
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>



	<xsl:template match="/page">
	<page>
		<xsl:value-of select="$XSP-ENVIRONMENT"/>
		<xsl:value-of select="$environment" />
	</page>
	</xsl:template>
</xsl:stylesheet>


PTOOI!!!! It threw up saying that XSP-ENVIRONMENT was being referenced out
of context or without definition. 
However, if I moved the variable definition for $environment into the
template, it worked fine.

Has anyone seen this happen? I don't want to change the ESQL source code
unless it needs to be changed... and anyway this error just does not make
sense! What am I missing?
Thanks!
