UnsatisfiedLinkError

[mantesat]

Hi all

I installed GWT Designer today, on an Eclipse 3.2.1 (and GWT 1.3.3), and I tried to visually edit some components created inside a project created using Googlipse. However, the editor always shows the "unknown window type" title, and the eclipse error log throws the exception:

It seems that for a strange reason, some dll is missing. In general, why can't the GWT Designer edit visually files created by googlipse or even by hand in projects not entirely created with GWT Designer from scratch? Should GWT Designer be used in projects created entirely with it?

TIA

It sounds like GWT Designer does not know where to find your GWT installation.

Did you convert the project to being a GWT Designer project?

Do you have a GWT_HOME classpath variable pointinhg to your GWT installation?

What version of GWT are you using and what version of GWT Designer?

In general, GWT Designer can edit files created elsewhere (even by hand). Both your project and GWT Designer need to be configured properly.

I tried to convert my project to GWT project (I didn't know that detail), but no luck. Error log said:

Designer internal error [6.1.1.20070213051843]: Build path contains duplicate entry: 'C:Projects/Libraries/GWT/gwt-windows-1.3.3/gwt-user.jar' for project

which is strange since there are no othet entries in the build path except from the GWT_HOME variable and the JRE runtime libraries.

I'm using GWT 1.3.3 and GWT Designer v1.5.1 (20070213053919)

If you create a new GWT project using GWT Designer, does the same thing happen? How is the .classpath and .project file for yoru first project different from a GWT Designer created project?

Can you send us this project as a test case?

[mantesat]

No, if a new GWT Project is created using GWT Designer, this doesn't happen.

I can send you this test project, just give me an e-mail address, or reply to this at mantesat AT talent.gr

You shoudl send it to our standard GWT Designer support address: wb-support@instantiations.com.

I'm seeing the exact same thing as well. It used to work but now when I needed to go back and open up the code again it doesn't. This time I needed to create a new project and GWT Designer blows up spewing tons of these exceptions. I manually modified the .classpath and .project to make it similar to that of a new project and it still doesn't work. This is very frustrating and makes using GWT Designer not very useful if I attempt to open up GWT files already created with GWT Designer and it doesn't work.
