I know how to set XP's enviorment variables in the advanced tab so I could do that. I am just writing this batch file. If I can get java, javac, and jar to work I would be happy and then work on ant.

I have the JRE and JDK installed. javac.exe and jar.exe are indeed in the bin directory. I did something and was for a small minute able to run javac and jar. Then I lost it. I think I went to the jdk's bin folder. Bill

I don't suppose you could unbend a little and actually quote (verbatim) those messages? -- Lew

I set the path variable in windows's environment settings in the advanced tab and not through a batch file and I can get javac and jar now. So now that I know I am not supposed to use a classpath I will forget all about it. Now is JAVA_HOME supposed to be set as path or as a new environment variable under the advanced tab? Should I create a new variable in the enviroment button in XP? Bill
