version problem in AbstractGenerator class

[Andreas Hefti]

hello all,

 

I try to write my own Generator for Cocoon to get XML source from a EJB. first I try to write a simle sample to find out how it works. I found a sample in a how to.

 

I wrote the following simple Generator:

 

---------------------------------------------------------------------------------

 

package com.ite.generators;

import java.io.IOException;
import java.io.StringReader;

import org.xml.sax.XMLReader;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.XMLReaderFactory;

import org.apache.cocoon.*;

public class TestGen extends org.apache.cocoon.generation.AbstractGenerator {

    public TestGen() {
    }

 

    public void generate() throws java.io.IOException, org.xml.sax.SAXException, org.apache.cocoon.ProcessingException {
        String message = "<doc>My first Cocoon 2 generator!</doc>";
     
        XMLReader xmlreader = XMLReaderFactory.createXMLReader();
        xmlreader.setContentHandler(super.xmlConsumer);
        InputSource source = new InputSource(new StringReader(message));
        xmlreader.parse(source);
    }   
   
   
}

 

--------------------------------------------------------------------------------

 

if I try to compile this source with Forte4Java 3.0, I get the following compiler error;

 

--------------------------------------------------------------------------------

 

com/ite/generators/TestGen.java [24:1] cannot access org.apache.cocoon.generation.AbstractGenerator
bad class file: D:\I-TE\Entwicklung\itech_cvs\develop\senn\src\webMod\WEB-INF\lib\cocoon-2.0.3.jar(org/apache/cocoon/generation/AbstractGenerator.class)
class file has wrong version 48.0, should be 47.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
public class TestGen extends org.apache.cocoon.generation.AbstractGenerator {
                                                         ^
1 error
Errors compiling TestGen.

 

---------------------------------------------------------------------------------

 

I', using the cocoon-2.0.3.jar. what is wrong with the class version and what can I do to solve the version problem?

 

thanks for any help,

Mit freundlichen Grüssen / Kind regards
