Hi all I'm using Text pad to edit and compile and run my Java applets/applications. what happened I'm new to classpath stuff,I don't know exactly what I did to the path,just I wrote at prompt c:\path and I changed some stuff,it is clearly I changed the set up for the classpath.Also i was trying to use -classpath to compile and run classes in different places,and i did many times (set classpath= ). The problem is:I can compile my java class from Text pad (tools/compile),but when I try to run it I get an alert that says: "the system cannot find the file specified ". I think i need to do something to appletviewer.exe.,because i can run application fine. Please help me with it,because now I can't run any applet Thanks for you time,I will appreciate your help.
