RE: Add Indexer using API

["Roth, Scott" <sc...@merck.com>]

I had a follow-up question on this topic.  I am trying to set up indexes
using xindice-1.1b1.  I used the below sample code as a simple test and
could not get the index to be created via RPC.  I am always getting
success="false" returned to my console.  So then I switched to the embedded
version to try to get better debug information from the System.out.println's
in the Xindice code.  However, the exact same code (with the exception of
"xindice" being changed to "xindice-embed") is working with the embedded
version.  I get this message:

Index node element =
        <?xml version="1.0"?>
<index class="org.apache.xindice.core.indexer.ValueIndexer" name="all"
pattern="
*" />

CREATED : all
True

Is there a known issue with index creation over RPC?  Or am I missing
something obvious?

The next step that I am considering is to start changing println's in the
Xindice code to logging messages to the tomcat log - but I want to avoid
touching Xindice code if possible.


Thanks,

Scott

Here's how I tested creating an index via the api: 

import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;
import org.apache.xindice.tools.command.*;
import java.util.*;

public class TestIndexer {

	public static void main(String[] args) {
		boolean success = false;
		AddIndexer ai = new AddIndexer();
		Hashtable h = new Hashtable();
		h.put("collection", "servicecodes");
		h.put("nameOf", "sc");
		h.put("pattern", "serviceCode");
		h.put("verbose", "true");
		try {
    		success = ai.execute(h);
		}
		catch (Exception e) {
			System.out.println(e.getMessage()); 
		}
		System.out.println(success);		
	}
}

collection is the name of your collection
nameOf is the name of the index
pattern in the above case is the element indexed on

You can look at the source code in AddIndexer.java for a more complete
understanding

If you are changing println's in the Xindice code (tool package), it's certain
that users will have problems when using the CLI...

But the Xindice code must be refactored so that external applications can use
features (like creating indexes) without using the tool.* classes.
