Running AWT from eclipse

[middy]

Well I get this error

Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-win32-3101 in java.library.path

Now before you say that I have to have the swt dll in my path. I also added this to my VM args -Djava.library.path=C:\nativelibs"

Her is the latest version of native SWT swt-win32-3106.dll

This VM argument works with another project requiring another dll

Now before you say that I have to have the swt dll in my path.

Unfortunately, that is exactly what I am going to say.

That error means only one thing. The SWT DLL is not on your path. Resolve that problem, and you will be fine.

If you want a quick solution, copy it into your windows/system32 directory.

Well I did try that already

Here is the full error

It looks like you are using the wrong version of the DLL. Note that the error refers to the 3101 version, and you earlier mentioned the 3106 version. Each version of Eclipse comes with a different version of that DLL which is matched to the corresponding SWT jar file. You can't mix and match them.

[middy]

I assumed that it was your designer that requested the 3101 version., not eclipse.

I checked eclipse 3.1 M1 AWT and there is was. I was convinced I had M2


Sorry for the trouble

[Eric Clayberg]

I assumed that it was your designer that requested the 3101 version., not eclipse.

Designer doesn't impose any runtime requirements. It will work with any version of Eclipse and SWT from v2.0 on.

I just came in here looking for a solution to a similar error. My difference is that I am getting that error on a Mac running 10.3.5. Why should it care if I have a Win 32 dll?

Thanks,
Brian

You don't need the Windows version of the DLL, but you might need the Mac equivalent. In general, if you are having problems getting SWT apps to startup at runtime, those questions should be posted to the Eclipse SWT newsgroup.
