Is there a .exe file to make .class files of .java files?

Thanks!

When you compile a javelin source file (.java) then a .class is written.
You can call jikes.exe (the compiler used by javelin IDE) directly from a commandline (dos box).

Does anyone have an example of how to compile from the command line with jikes? I read the manual but its still confusing. Such as the classpath flag looks like it should be pointing to a zip/jar file but the source isn't in an archive.

Javelin example that should work (assuming Javelin IDE installed in default directory)
jikes -classpath "c:\program files\parallax inc\javalin stamp ide\lib;c:\program files\parallax inc\javalin stamp ide\projects;" file.java

Thanks, I tried something like that and it worked. I am using the MATLAB system out command to run the compiler, this goes into an automated code generation system so that MATLAB can talk to the Javelin stamp as if it were DAQ I/O lines.

Scott these are the command I use:

"C:\Program Files\Parallax Inc\Javelin Stamp IDE\jikes\jikes.exe" +E -depend -g "C:\Documents and Settings\Jonathan\Desktop\javelin\code\javelin\%*.java" -classpath "C:\Documents and Settings\Jonathan\Desktop\javelin\code\javelin;"

"C:\Documents and Settings\Jonathan\Desktop\javelin\javelin direct\JavelinDirect.exe" JavelinDirect --path "C:\Documents and Settings\Jonathan\Desktop\javelin\code\javelin" --port 8 --listen %*

You will need to change the path but you can get an idea!
