I had jdk1.1.8 installed on my computer. Recently I changed my os now XP(Prof). Java is not working. I reinstalled file. My Add /remove program show java development kit1.1 (20 MB) installed. I set the path C:\jdk1.1.8\bin and tried to compile javac <file name.java> .Error message file not found.Do I need to install latest version from sun or I am not able to define path /directories properly? Can someone guide me to see if the compiler is working. I need detailed explaination on this. Thanks
