Re: java processor problems

[Alessandro Vernet]

Hi Peter,

1) You are probably getting this exception because of the JDK version 
you are using. You need the JDK 1.4.1 or 1.4.2 to use the Java 
processor. If you cannot upgrade, just let us know and we'll see what 
we can do to port this functionality to older versions of the JDK.

2) You seem to be using the addSocketInfo(...) method in your custom 
processor. With OXF 2.1 you should now call: addOutputInfo(new 
ProcessorInputOutputInfo(OUTPUT_DATA)). The OXF 2.1 documentation has 
unfortunately not been modified to reflect this; I apologize for this. 
Note that if you use the old API with the OXF 2.1 you will get a 
compilation error.

3) We have added an example using the Java processor. It will be part 
of the next release of OXF.

Hi All,

I'm having difficulties getting the java processor to work. My processor looks 
like:

<p:processor uri="oxf/processor/java" 
xmlns:p="http://www.orbeon.com/oxf/pipeline";>
	<p:input name="config">
  	<config srcpath="aa-form" processor="DeepThoughtProcessor.java"/>
  </p:input>
  <p:output name="data" ref="data" debug="java-out" id="java-out"/>
</p:processor>

And the code isd as per the documentation DeepThoughtProcessor:

import org.orbeon.oxf.processor.pipeline.PipelineContext;
import org.orbeon.oxf.processor.ProcessorInputOutputInfo;
import org.orbeon.oxf.processor.SimpleProcessor;
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.AttributesImpl;
public class DeepThoughtProcessor extends SimpleProcessor {

    public DeepThoughtProcessor() {
        addSocketInfo(new ProcessorSocketInfo
            (ProcessorSocketInfo.OUTPUT_TYPE, OUTPUT_DATA));
    }
    public void generateData(PipelineContext context,
                             ContentHandler contentHandler)
            throws SAXException {
        String answer = "42";
        contentHandler.startDocument();
        contentHandler.startElement("", "answer", "answer", new 
AttributesImpl());
        contentHandler.characters(answer.toCharArray(), 0, answer.length());
        contentHandler.endElement("", "answer", "answer");
        contentHandler.endDocument();
    }
}

This generates a NoSuchMethod Error:
com.sun.tools.javac.Main.compile([Ljava/lang/String;Ljava/io/PrintWriter;)I
(The full stack trace is below)

I have recently upgraded from OXF2.0.2 to 2.1 and according to the 
documentation, the line 
<config srcpath="aa-form" processor="DeepThoughtProcessor.java"/>
Should read 
<config sourcepath="aa-form" class="DeepThoughtProcessor.java"/>
But OXF doesn't recognise those attributes.

Any ideas?
