Error return from Host Command

Question

I use procedure below to run Win commands from stored procedure, Had found this last year by searching in this forum and it works fine.
However this procedure lacks facility to return if command was succesful on OS.
All I want is for Oracle to be able to pick up value of windows variable: %errorlevel% after command has been executed. If necessary I will include " echo %errorlevel% "in a batch file.
I am patching up somehow but it is too slow. I am currently saving %errorlevel% in a txt file and then using sqlldr to load value in an Oracle table. But this takes about 40 seconds to execute (time needed to open a new session each time).
I would rather have Java procedure pick up result of batch command directly.

CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED HOST AS
import java.lang.*;
import java.io.*;
public class Host
public static void executeCommand (String command, String etype) throws IOException
String[] wFullCommand = {"C:\\winnt\\system32\\cmd.exe", "/y", "/c", command};
String[] uFullCommand = {"/bin/sh", "-c", command};
if (etype.toUpperCase().equals("W"))
Runtime.getRuntime().exec(wFullCommand);
else if(etype.toUpperCase().equals("U+"))
Runtime.getRuntime().exec(uFullCommand);
else if(etype.toUpperCase().equals("U"))
Runtime.getRuntime().exec(command);
CREATE OR REPLACE PROCEDURE Host_Command_Proc
( p_command IN VARCHAR2,
p_etype IN VARCHAR2)
AS
LANGUAGE JAVA
NAME 'Host.executeCommand (java.lang.String, java.lang.String)';
