error when compiling the applet code

[sandy]

Hi all,

i am creating new project using http://code.google.com/p/gwtai/wiki/GettingStarted
and a class which is extending JApplet , in the same class i have
written applet code. i am seeing -
(The serializable class CounterAppletImpl does not declare a static
final serialVersionUID field of type long
- javax.swing.JApplet is not supported by Google App Engine's Java
runtime environment)

Any help would be greatly appreciable.

Thanks
Sandeep

Try just inserting this field into your CounterAppletImpl class.

private static final long serialVersionUID = 1;

Another fix would be that if your class implements "serializable", to remove that interface support from the class - but then again, maybe in that case Google Apps might not support the applet ... not exactly sure how this works.

Hi Jason,

Can help me giving some sample project of Applet integrated with GWT, I am using windows OS and Eclipse  for developing my project. I got some some sample projects from the group but they are not working in my environment. Please help me with  some sample project with my environment, so that i can refer to that and design according to my requirements.

Thanks

Hi Sandeep

This is the most simple project I can think of. I have just integrated
a really simple Applet and configured the JarLinker to create the
necessary Jar file.

You can import the project in Eclipse and run developer mode...

Thanks

Hi Sandeep

You are using a JRE to run the GWT developer mode. In this context
that does not work, because the JRE does not contain a jarsigner. The
jarsigner is bundeled with the JDK. The best thing is to install a
JDK, point your Eclipse (Preferences -> Installed JRE) to this JDK and
use it to run the GWT developer mode.

Regards, Adrian
