Help for running SWT projects under 3.1 !!! [message #457816]

To run a project with SWT code in it under 3.0, it was enough to include
plugins\org.eclipse.swt.win32_3.0.1\ws\win32 jar
in the project build path
and run the program with JVM flag :
Djava.library.path=C:\dev\Eclipse3\eclipse\plugins\org.eclip se.swt.win32_3.0.1\os\win32\x86

(under Windows).

I try to do the same under Eclipse 3.1.....

included this jar (if not nothing compiles well):plugins\
org.eclipse.swt.win32.win32.x86_3.1.0.jar

try to use this JVM flag when run project:

Djava.library.path=C:\dev\eclipse3.1RC3\eclipse\plugins\org. eclipse.swt.win32.win32.x86_3.1.0

but exception says library not found at run time:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-win32-3138
in java.library.path

What is the right procedure now ???????

Thnaks for helping

In the menubar: Run/Debug as/SWT Application.

It can't be simpler than that.

Running the app outside Eclipse is another story though. For this you need
to download the Standalone SWT package and follow the instructions for
running your app with it. Mostly these follow what you've done in Eclipse
3.0 so far for running SWT.

If you need advanced info as to what is going on, the problem is, now the
SWT DLLs are inside the SWT feature jar. You can't put in -Djava.libray.path
JAR files that contain DLLs - only directories. How Eclipse handles that,
you'll ask? Well, Eclipse Platform Runtime extracts these DLLs in a temp
directory just at the start of Eclipse.

Ivan,

Many thanks. My problems came from the fact that for a while i used 3.1RC3.
and under RC3, there is NOT ANY "run as/SWT application" item (Run as Java
application" is the only choice left.
This option reappered under 3.1 final.....
