this piece posted works almost fine:
<xsl:template match="xsp:page">
<xsp:page>
<xsl:apply-templates select="@*"/>
<xsp:structure>
<xsp:include>org.apache.cocoon.components.language.markup.xsp.XSPUtil</xsp:include>
<xsp:include>org.apache.avalon.framework.context.ContextException</xsp:include>
</xsp:structure>
<xsp:logic>
public void contextualize(Context
context) throws ContextException (
uploadDir = (File)
context.get(Contstants.CONTEXT_UPLOAD_DIR);
}
String[] filelist = uploadDir.list();
</xsp:logic>
<xsl:apply-templates select="node()"/>
</xsp:page>
</xsl:template>
The only problem: It always gives a nullpointer-exception, because the "uploadDir.list()" is empty (for some stupid reason).
In my xsp's this code works fine. It gets all the names of the files(+directories) of the upload-directory I specified in the web.xml file (and in my case this directory isn't empty).
Thanks Jonny

what does your XSP program (the one that uses this logicsheet) look like? It looks to me as if you are either putting a function inside the main generate() function, or else you are putting XML output code outside any function (at the class level). Based on your syntax error, I suspect the former. You have: <xsl:template match="jonny:test"> <xsp:logic> File uploadDir = null; /** Contextualize this class */ public void contextualize(Context context) throws ContextException { uploadDir = (File) context.get(Constants.CONTEXT_UPLOAD_DIR); } String[] filelist = uploadDir.list(); </xsp:logic> <xsp:expr>filelist[0]</xsp:expr> </xsl:template>
The first few lines define variables and functions, which are legal outside any function in the class, e.g., inside an <xsp:logic> statement nested directly under the <xsp:page> element. The last line does <xsp:expr>filelist[0]</xsp:expr>, which turns into a line of bare java code, that isn't legal outside any function at the class level. So this is confused.
You may need to move part or all of your xsp:logic block (at least the part defining the contextualize() function) up into your template matching <xsp:page>, e.g.:
<xsl:template match="xsp:page"> <xsp:page> <xsl:apply-templates select="@*"/> <xsp:structure>
<xsp:include>org.apache.cocoon.components.language.markup.xsp.XSPUtil</xsp:include>
<xsp:include>org.apache.avalon.framework.context.ContextException</xsp:include>
</xsp:structure>
<xsp:logic>
public void contextualize(Context
context) throws ContextException (
uploadDir = (File)
context.get(Contstants.CONTEXT_UPLOAD_DIR);
}
</xsp:logic>
<xsl:apply-templates select="node()"/>
</xsp:page>
</xsl:template>
alternatively, perhaps you want
<xsl:template match="jonny:test"> <xsp:logic> File uploadDir = null; /** Contextualize this class */ try{ uploadDir = (File) context.get(Constants.CONTEXT_UPLOAD_DIR); } catch ContextException e { ... } String[] filelist = uploadDir.list(); </xsp:logic> <xsp:expr>filelist[0]</xsp:expr> </xsl:template>
The important thing is to remember that you are applying a stylesheet to transform an XSP program into another XSP program. Think about what the resulting, transformed program looks like (or test it by applying the stylesheet yourself to see what the result is). -Christopher

Hi,
now I changed the logicsheet: __________________________________________________________________________________
<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xsp="http://apache.org/xsp"; xmlns:jonny="http://jonny.de/jonny";> <xsl:template match="xsp:page"> <xsp:page> <xsl:apply-templates select="@*"/> <xsp:structure>
<xsp:include>org.apache.cocoon.components.language.markup.xsp.XSPUtil</xsp:include>
<xsp:include>org.apache.avalon.framework.context.ContextException</xsp:include>
</xsp:structure>
<xsl:apply-templates select="node()"/>
</xsp:page>
</xsl:template>
<xsl:template match="jonny:test">
<xsp:logic>
File uploadDir = null;
/** Contextualize this class */
public void contextualize(Context context)
throws ContextException {
uploadDir = (File)
context.get(Constants.CONTEXT_UPLOAD_DIR);
}
String[] filelist = uploadDir.list();
</xsp:logic>
<xsp:expr>filelist[0]</xsp:expr>
</xsl:template>
<xsl:template match="@*|node()" priority="-2">
<xsl:copy>
<xsl:apply-templates
select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
But it still throws an error: ______________________________________________________________________________

_______________________________________________________________-
The strange thing here is (in my opinion) that I got these errors before in
my xsp's with the same code. But now they're gone in the xsp's and I have em in the logicsheet.
Thanks jonny
