Using .bat file to run java application

Question

I want to be able to trigger Java class from SQL command. SQL statement will execute batch file, which contains all information about my java class and about CLASSPATH variable.
Unfortunately, it does not work as planed. I get this message in Query Analyzer:
output Compile first.
RUN COMPILED FILE NOW
java.lang.NoClassDefFoundError: \\finkelsteine\autotest\CommandLineTest
Exception in thread "main"
(4 row(s) affected)
Here is SQL I use:
DECLARE @cmd varchar(1000),
@result int
SET @cmd = '\\mycomputer\autotest\autotest.bat'
EXEC @result = master..xp_cmdshell @cmd
select @result
Here is the autotest.bat file:
@ECHO OFF
SET PATH=%PATH%;C:\jdk1.2.2\bin;C:\jdk1.2.2\jre;C:\jdk1.2.2\lib
SET CLASSPATH=c:\autotest;%CLASSPATH%
ECHO Compile first.
javac c:\autotest\CommandLineTest.java
ECHO RUN COMPILED FILE NOW
java c:\autotest\CommandLineTest
Here is my CommandLineTest.java file
import java.io.*;
public class CommandLineTest
public CommandLineTest() {
super();
public static void main(java.lang.String[] args)
File file = null;
PrintWriter out = null;
file = new File("c:\\autotest\\test.txt");
try
// Create an output stream
out = new PrintWriter(new BufferedWriter new FileWriter(file)));
out.println("Hello there");
out.flush();
out.close();
catch(IOException ioex)
ioex.printStackTrace();
System.out.println("IO exception");
please help.

Answer 1

The argument to the java command is the name of the class to run, not a path to the class file. You must have the classpath environmental variable set up properly for the class to run.
