Where to put external archives to configure running in Eclipse?
- by Buggieboy
As a Java/Eclipse noob coming from a Visual Studio .NET background, I'm trying to understand how to set up my run/debug environment in the Eclipse IDE so I can start stepping through code.
I have built my application with separate src and bin hierarchies for each library project, and each project has its own jar. For example, in a Windows environment, I have something like:
c:\myapp\myapp_main\src\com\mycorp\myapp\main
...and a parallel "bin" tree like this:
c:\myapp\myapp_main\bin\com\mycorp\myapp\main
Other supporting projects are, similarly:
**c:\myapp\myapp_util\src\com\mycorp\myapp\uti**l (and a parallel "bin" tree.)
... etc.
So, I end up with, e.g., myapp_util.jar in the ...\myapp_util\bin... path and then add that as an external archive to my myapp_main project.
I also use utilities like gluegen-rt.jar, which I add ad external dependencies to the projects requiring them.
I have been able to run outside of the Eclipse environment, by copying all my project jars, gluegen-rt DLL, etc., into a "lib" subfolder of some directory and executing something like:
java -Djava.library.path=lib
-DfullScreen=false -cp lib/gluegen-rt.jar;lib/myapp_main.jar;lib/myapp_util.jar;
com.mycorp.myapp.Main
When I first pressed F11 to debug, however, I got a message about something like /com/sun/../glugen... not being found by the class loader.
So, to debug, or even just run, in Ecplipse, I tried setting up my VM arguments in the Galileo Debug - (Run/Debug) Configurations to be the command line above, beginning at "-Djava.libary.path...". I've put a lib subdirectory - just like the above with all jars and the native gluegen DLL - in various places, such as beneath the folder that my main jar is built in and as a subfolder of my Ecplipse starting workspace folder, but now Eclipse can't find the main class:
java.lang.NoClassDefFoundError:
com.mycorp.myapp.Main
Although the Classpath says that it is using the "default classpath", whatever that is. Bottom line, how do I assemble the constituent files of a multi-project application so that I can run or debug in Ecplipse?
