Re: XSLTC, abbreviated syntax for extension implemented in Java and Compiler error(s): Cannot find external method ...

[Mariella Di Giacomo <ma...@lanl.gov>]

Hi,

I am sorry for the "." after the package name but it is a typo.
I have tried also what you have written in the email, but I still get

java org.apache.xalan.xsltc.cmdline.Compile xslt_functions.xsl
Compiler error(s):
   Cannot find external method 'parseQuery.new' (must be public).
   Cannot find external method 'getVdkKey' (must be public).
   Cannot find external method 'getSessionId' (must be public).

Could you please help ?
Thanks,

Mariella


This is how the xsl file looks like

_____________________________
<?xml version="1.0"?>
<xsl:stylesheet
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

     xmlns:xalan="http://xml.apache.org/xalan"
     xmlns:XSLTFunctionsPackage="xalan://pack1.team.xsltfunctions"
     version="1.0">

   <xsl:variable name="myType" select="XSLTFunctionsPackage:parseQuery.new()"/>

    <xsl:variable name="vdkKey" 
select="XSLTFunctionsPackage:getVdkKey($myType)"/>
   <xsl:variable name="tmpFileName" 
select="XSLTFunctionsPackage:getSessionId($myType,$vdkKey)"/>

</xsl:stylesheet>

__________________________________________

This is how the Java class looks like:
_____________________________________________________


package pack1.team.xsltfunctions;

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;


public class parseQuery extends HttpServlet {

   static String mVdkKey = "";
   static String mRestOfUrl = "";
   static String mSessionId = "";
   static String mDbsSearched = "";



   public void parseQuery()
     {}

   public void setVdkKey(String pVdkKey) {
          mVdkKey = pVdkKey;
   }

  public String getVdkKey() {
          return mVdkKey;
     }



  public String getSessionId() {
          return mSessionId;
   }

................
}

The JAVA classpath contains the pathname of the jar file
that contains that class.
