1. You need to install jacorb to use this stuff. See my notes in the CipresDev section of the fsu wiki on installing jacorb. 2. Note: this hasn't been tested on windows in a while. On windows, I use a batch file like the following to set up for running jacorb programs from the command line: set JAVA_HOME=c:\JBuilderX\jdk1.4 set ANT_HOME=c:\ant set PATH=%PATH%;%JAVA_HOME%\bin;%ANT_HOME%\bin;c:\jacorb\bin set CLASSPATH=%CLASSPATH%;. # Make CIPRES_IDL_ROOT point to the directory that contains the .idl files. set CIPRES_IDL_ROOT=c:\JBuilderX\jbprojects\framework\commlib\IDL 3. Before you try to build this project you need to generate java code from the idl. Running generate.bat should invoke the jacorb idl compiler Files will be generated in a subdir named org/cipres/CipresIDL. 4. When you build the other cipres components (like the app) using JBuilder, you'll need to add two things to their required libraries: - this project - a jacorb.library which includes the jacorb jar files.
