Hi,
I'm using Eclipse 3.0M2 on Mac OSX 10.2 and Windows 2000 Prof.
I'm automating Canto Cumulus (an Asset Management tool) with java
and to be able to do this an environment variable has to be defined
in MAC OS X.
From the terminal I do
sh (to start a shell)
export DYLD_LIBRARY_PATH=/usr/local/CumulusJC5/lib
javac myprogram.java
java myprogram
and this works
But from within eclipse I get an error
Exception in thread "main" java.lang.UnsatisfiedLinkError: no CumulusJC in
java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1403)
at
java.lang.Runtime.loadLibrary0(Runtime.java:788)
at
java.lang.System.loadLibrary(System.java:832)
at
com.canto.cumulus.Cumulus.CumulusStart(Cumulus.java:447)
at
com.canto.cumulus.Cumulus.CumulusStart(Cumulus.java:390)
at
CCSI.test1(CCSI.java:660)
at CCSI.main(CCSI.java:19)
What shell does Eclipse use and how do I set this pathvariable?
Or can I somehow have java itself look into that directory
(java.library.path)?
I do not have the soourcecourde of the Cumulus-javaclasses, just a JAR.
So I can change it their...
Thanks for any help...

Instead of setting an environment variable you can specify the library
directory via a command line argument for the compiler and Java VM.
If your Cumulus library contains native code (and is accessed from Java via
JNI) you will have to add it to the java.library.path of the Java VM as
follows:
java -Djava.library.path=/usr/local/CumulusJC5/lib
If the library is just a Java archive (*.jar) you'll have to pass is to the
compiler:
javac -classpath /usr/local/CumulusJC5/lib myprogram.java
and the VM:
java -classpath /usr/local/CumulusJC5/lib myprogram
When launching Java programs from within Eclipse you typically don't have to
specify the classpath manually.
And the Java library path can be specified in the "Run..." dialog. Select
your configuration and select the "Arguments" tab. In the VM arguments field
enter:
-Djava.library.path=/usr/local/CumulusJC5/lib

Whel OsX is BSD but is is a special kind
As you moslikely know you can set enviroment-vars in
/etc/profile(systemwide) or in the users bash.rc files.
This is how it is done for a shell scripts etc.
BUT !!
To run a java application like it should something else is needed
(in fact to run any aplication)
OSX knows something like .plist files they contain information about the
enviroment an d arguments to use when running an aplication and they
recide in the app's bundle (wich is in fact a folder).
You can open the file like this:
In the finder click on eclypse and press and hold <CTRL>
select "show package contents"
open the Contents folder
open Info.plist in a good text-editor (BBEdit)
or yust click on it so that it opens in your standard plist-editor.
You will discover a nice xml-file wich looks like this
(i'll added comments to explain the functions but you have to remove them ):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
