problem about setting java.library.path property [message #296735]

hi,

I am trying to specify the java.library.path property in Eclipse but had
no idea how to do it. After some google work, I read some thing like " there
is no way to do this in IDE, instead has to do it with path variable in
system(windows environment)". I include my DLL path in the path variable in
system but nothing happen, the printed java.library.path still point to some
strange cache like
" D:\...\workspace\.metadata\.plugins\org.eclipse.ve.java.core \.cache\.libCache\-1927741210 ".
and the program gave me a unsatisfied linked error again.

I can specify the -Djava.library.path=..... and in this way, the program
works well. But I still would like to have a normal way to set this property
before hand rather then specify it for each program that need to be run.

Any idea of how to fix this problem? Thanks!

In the launch-configuration ("run...", "debug...") you can specifiy the
following under vm-args:
-Djava.library.path=...

Thanks feri,

Doing in this way, the program works well. But is it the only way to do
it? Isn't there somewhere in eclipse that I can set this property for all
the runnable classes so that I do not need to sepcify this everytime when I
want to start a class?

There's a way to specify that your plugin has a native library location
.... so that any launch from within eclipse will include that information
automatically.

If you download and import the swt SDK from http://www.eclipse.org/swt/
you'll see how they did it.

My SWT works well with its dlls. (Can not remember How I did it:))But does
it have to be a plugin to be able to pre-set the path? Currently I have some
my own developed dlls in different directories, it is quite cumbersome to
specify all these dirs with -Djava.library.path.

No, that's the point ... not the SWT plugin, but the SWT SDK (from the
link I mentioned) which is an eclipse java project. Check out how they
did it.

I think they added their jar to the build path, and then added native
libraries to the jar. Maybe you can adapt that somehow.
