Can't launch the sample project

[Valentin Torikian]

Hello,

I'm new to GWT, it seems to be a great tool, but unfortunately I can't properly launch the sample app (the one created by default when creating a new GWT project). When I launch it and click on the "Send" button I got this error browser side:

------------------------------------------------------------

Sending name to the server:

GWT User

Server replies:

An error occurred while attempting to contact the server. Please check your network connection and try again.

------------------------------------------------------------

And this error serverside:

Avertissement: Error for /woweco/greet

java.lang.VerifyError: Expecting a stackmap frame at branch target 6 in method com.oxymore.woweco.server.GreetingServiceImpl.escapeHtml(Ljava/lang/String;)Ljava/lang/String; at offset 1

I got the GWT for Eclipse plugin installed on my laptop (it crash on this machine), and on my desktop (it runs fine).

Thanks in advance for your help!

Go Eclipse -> Window -> Preferences
Choose Java -> Installed JREs -> click on your JRE and push Edit.
