SAX parsing problem?
Hi All,
I am converting an application from C1 to C2.
I had a working XSP file with this code snippet:
<?xml version="1.0"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet href="gs.xsl" type="text/xsl"?>
<xsp:page language="java" xmlns:xsp="http://www.apache.org/1999/XSP/Core"
xmlns:util="http://www.apache.org/1999/XSP/Util"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xslt.extensions.Redirect"
extension-element-prefixes="xalan"
xmlns:lxslt="http://xml.apache.org/xslt"
version="1.0">
<xsp:structure>
<xsp:include>java.lang.*</xsp:include>
<xsp:include>java.util.*</xsp:include>
<xsp:include>java.io.*</xsp:include>
<xsp:include>com.kg.replicate.*</xsp:include>
</xsp:structure>
<page>
<xsp:logic>
String strUserID;
String strPwd;
String strPlayerID;
String strHttp;
strUserID = request.getParameter("userID");
strPwd = request.getParameter("pwd");
strPlayerID = "";
String strKGUser;
String strKGPwd;
KGParse kgParse = new KGParse();
,,,
In order to use actions in C2, I converted it to a Java class,
containing the following code snippet.
package com.kg.gs;
import java.lang.*;
import java.util.*;
import java.io.*;
import org.w3c.dom.*;
import com.kg.replicate.*;
import org.apache.avalon.framework.parameters.Parameters;
import org.apache.cocoon.acting.AbstractAction;
import org.apache.cocoon.Constants;
import java.util.Map;
import java.util.HashMap;
import org.apache.cocoon.environment.Redirector;
import org.apache.cocoon.environment.Request;
import org.apache.cocoon.environment.SourceResolver;
import org.apache.cocoon.environment.ObjectModelHelper;
public class GSLoginAction extends AbstractAction
{
public Map act (Redirector redirector,
SourceResolver resolver,
Map objectModel,
String source,
Parameters params)
{
String strUserID;
String strPwd;
String strPlayerID;
String strHttp;
strPlayerID = "";
String strKGUser;
String strKGPwd;
Request request = ObjectModelHelper.getRequest(objectModel);
strUserID = request.getParameter("userID");
strPwd = request.getParameter("pwd");
KGParse kgParse = new KGParse();
....
When I execute this version it bombs in the KGParse() constructor with the
following exception.
The stack trace:
java.lang.VerifyError: (class: com/kg/replicate/KGParse, method:
parseInputSource signature:
(Lorg/xml/sax/InputSource;)Lorg/w3c/dom/Document;) Incompatible object

My package com.kg.replicate.* has not changed. Does anyone know what the
problem is?
My environment is apache tomcat 4.0.3, WinNT 2K, jdk 1.3.1_01, cocoon
2.0.2-dev
Thanks very much,
Leona

Re: SAX parsing problem?
Posted by Liam Morley <lm...@gdc.wpi.edu>.
I'm sorry, what I meant was, what happens in the code? It looks like you
posted the first 15 lines of your GSLoginAction class, but I was curious
what was happening at line 46 and thus throwing the exception.

Sorry Liam,
I was a bit too hasty in cut and paste.
This is the entire error that happens at the offending line,
GSLoginAction.java:46.> KGParse kgParse = new KGParse();
KGParse is extended from
Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error

RE: SAX parsing problem?
Posted by Vadim Gritsenko <va...@verizon.net>.

your library there.
