Thanks Marc, 
        I  will look into the solution and will make the necessary
modification as applicable.

Here is the problem and solution:

The problem is that the jndi provider supplies a namespace for dsml,  
but not se causing crimson to crash.  As the namespace is ignored in  
the DSMLReader, namespace validation can be turned off.  This causes  
the tag name to include the prefix.  To compensate for this, in  
startElement and endElement add the following code:

//this allows for namespace prefix's to be present but ignored
		  int colonIndex = strQName.indexOf(':');
		  if (colonIndex != -1) {
			  strSName = strQName.substring(colonIndex +
1);
			  strQName = strSName;
		  }
		  else {
			  strSName = strQName;
		  }

to trim off the prefix if it's there.

This brought me to another problem, I am trying to write a search  
response by creating an LDAPEntry object then writing it using the  
writeEntry method, but this isn't creating the searchResponse tags.  I 

tried writing "new LDAPRespone(LDAPMessage.SEARCH_RESPONSE)" but this 

causes a NullPointerException:
