java.lang.UnsatisfiedLinkError: no swt-win32-3063

Hi,

I am taking SWT Designer out for a test drive and walking through the AddressBook example. When I try to run this as a Java Application I receive the following error:

java.lang.UnsatisfiedLinkError: no swt-win32-3063 in java.library.path

Any help is greatly appreciated.

As stated in the product docs and tutorial, you need to make sure that the Eclipse SWT DLL is on your path.

I'm getting the same exception as in the original post. The curious thing is that I am able to run an SWT Application that is in a different project with no problems. Both projects were created as Java/SWT Projects, I see no differences in the project settings for either, yet one runs and the other doesn't. the SWT DLL is in my jre\bin directory which is on my PATH.

Thoughts?

Thanks,
Chuck

Every Eclipse and SWT build has its own unique SWT DLL (identified by the last four number in its name). If you are getting that error, it means that you either don't have the DLL on your path, or you have the wrong version on your path. It is very easy to create classpaths and launch configurations in the wame workspace that target different versions of Eclipse and different SWT DLLs. Thus, it is not at all surprising that an SWT app in one project would work while another in a different project would fail. You need to reexamine your assumptions and very carefully check which version of SWT each project (or launch config) is referencing. If the error mentions a specific version of the SWT DLL, find that version and put it on your path (e.g., dump it into your windows/system32 directory) and be done with it.
