Hi,
I am calling another GWT app from within KK. The app uses an RPC servlet. When the servlet is called, I get the following error.
"Exception while dispatching incoming RPC call javax.servlet.ServletException: Content-Type must be 'text/plain' with 'charset=utf-8'"
The GWT app was developed with GWT 1.5.2.
What version of GWT does KK use anyway?
Below is a log.
Anyone interested in helping?
Thank you.

The 2.2.6.0 release uses GWT 1.4.61 - but we have plans to use 1.5.2 in the next release.
Could it be that you're getting problems with incompatible gwt jars?
Kate
Thank you for your response, Kate.
Yes, Googling seems to indicate that this problem has occurred for some when moving from 1.4 to 1.5.
Do you know when the next release may happen?
Meanwhile, I will try to find what is needed to build with 1.4.61 to see if that affects the problem.
Regards :)
Hi,
I'm afraid I don't know when the next release is due out... however there are no immediate plans.
Kate
Kate,
For those who may have similar exceptions when using recent version of GWT, I modified my GWT app for 1.4.62 and that does fix the problem. Thank you.
