xquery with java under linux

I’m tryng to run a xquery from a java environment under linux
usign jdk 1.4.
In the previous post i found an example and i tried to use it:

import java.util.;
import com.softwareag.xtools.quip.xqueryAPI.
;

public class XQL2 {

public static void main(String [] args){
Properties prop = new Properties();
StringBuffer stringbuffer1 = new StringBuffer();
try {
stringbuffer1.append( “file://home//federico//xquery” );

prop.put(“home”,"/home/federico/xquery" );
prop.put(“quipcmd”,"/home/federico/xquery/QuiP/quip" );
Connection conex
= DriverManager.getConnection(stringbuffer1.toString(),(Properties)prop);
QueryResult res = conex.executeQuery(args[0]);
System.out.println(res.getRawString());
}catch (XQueryException e) {
System.out.println("XQueryException: " + e.getMessage());
}
}
}

and this is the result i get…
<?xml version="1.0" encoding="UTF-8" ?>

<quip:ExecutionError xmlns:quip=“http://namespaces.softwareag.com/tamino/quip/”>
quip:queryFile/tmp/Query62820.tmp
</quip:queryFile>
quip:message<![CDATA[Error (1,1): accessing unspecified implicit input document
]]></quip:message>
</quip:ExecutionError>

there’s something that i don’t understand…
can you help?

ok. I found a solution. the actual problem is that you don’t pass to quip a file like calling it from the shell, but you have to pass a string with the query. I hope this help, many of you.
