java.lang.ClassNotFoundException & AnonymousTypeDeclaration2

[bouba331]

Hi,

I've just installed the GWT Deisgner Eclipse Plugin but encouter a ClassNotFoundException related to JDT Core.

What i've done to produce this exception is:
- Create a DialogBox using File -> New -> Other ... -> WindowBuilder -> GW Designer -> Basic UI -> DialogBox
- Open the generated DialogBox Java File
- Click on the Design View Tab

The generated Exception is:

Ok, I've checks the Eclipse JDT core JAR from my Eclipse Galileo 3.5.2 and thei is no org.eclipse.jdt.core.dom.AnonymousTypeDeclaration2 class in the JAR (org.eclipse.jdt.core_3.5.2.v_981_R35x.jar).

I've also tried to see if this class is present in older and newer JDT JAR but found nothing in the following JAR versions:
- org.eclipse.jdt.core_3.5.0.v_963.jar
- org.eclipse.jdt.core_3.5.1.v_972_R35x.jar
- org.eclipse.jdt.core_3.5.2.v_981_R35x.jar
- org.eclipse.jdt.core_3.6.0.v_A58.jar

The version of the GWT Designer i'm using is :
- GWT Designer
- CSS Editor 8.0.0.r35x201009131454
- GWT Designer 8.0.0.r35x201009160831
- GWT Designer Core 8.0.0.r35x201009140724
- Infrastructure
- Shared 6.0.0.r35x201009131414
- WindowBuilder Common UI Support 8.0.0.r35x201009131432
- WindowBuilder Core 8.0.0.r35x201009160631
- WindowBuilder XML Core 8.0.0.r35x201009160634

So where is this AnonymousTypeDeclaration2 class ?
What could be the problem ?

Thanks,

Baptiste

That ClassNotFoundException indicates that the product was only partially installed.

Do a full install (preferably into a new, clean Eclipse environmental), and it will be fine.

Also make sure that you are your Eclipse environment includes the full JDT and PDE as stated in the product system requirements.
