Thanks again. > > Warm Regards, > > Selvan Pillaai. I'm not sure what the problem is. The 'Start: applet not initialized string' is from jdk1.2.2/lib/tools.jar, which is used by appletviewer. My guess is that the applet is not being started in the directory where the codebase applet parameter thinks it is being started If you have moved the files around, then you will need to restructure the applet tag. It could be that your CLASSPATH is not being propagated to appletviewer. You are using the DOS shell, so I believe that if you set your CLASSPATH in the Environment tab of the System control panel then appletviewer should in theory see the CLASSPATH change. I'm not sure about the directory structure you are using, the Ptolemy II 0.4beta distribution usually ends up in a directory called ptII0.4beta. Since you are using a DOS prompt, this could be causing problems with 8.3 names. You might try installing Cygwin and using the bash shell, which understands full names. Also, I'm not sure what operating system you are running under. We have used Ptolemy II 0.4 under NT4.0 extensively, but to my knowledge, we have never tested it under Windows 98. We are starting to use Windows 2000. Also, you might check out some of the applet resources in http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII0.4/ptII0.4/doc/index.htm to get a better understanding of how applets work. You might try compiling a small applet, such as the Blink applet from the tutorial, and get that working. You could try converting the applet to an application, but I think you would likely run in to similar problems. My guess is that you are having CLASSPATH and directory problems. CLASSPATH is one of the worst aspects of Java. Only in the more recent releases have they started to fix some of the big problems. It is too bad that the CLASSPATH variable uses different separators on different platforms - so much for write once, run everywhere. -Christopher ---------------------------------------------------------------------------- Posted to the ptolemy-hackers mailing list.
