could not evaluate javascript response: Invalid characters? [message #546403]

Hi all experts,

I wrote a RAP application and deployed it to tomcat running on a Linux OS.

The problem is that when I restart the service and try to start a new sesssion, The IE explorer get the error message that "could not evaluate javascript response: Invalid characters"

The problem cannot be reproduced every time when restart the service.
When this problem occurs, I reopen a new IE explorer, and it works fine.

I saved the error page and tracked the source code of the html file, finding that the parameter of charset might be probably wrong:
"<meta http-equiv="Content-Type" content="text/html;charset=unicode" />".

The parameter "charset" there was set to "unicode" while in cases the application runs well it is set to "UTF-8".

Could you please have a glance on this problem?

Thanks and Best Regards!

Hi,

it sounds like this bug:
298181: [encoding problem] encoding of the initial html page is not
specified, and thus is not always utf-8
https://bugs.eclipse.org/bugs/show_bug.cgi?id=298181
which has been fixed in RAP 1.3M5 and backported to maintenance branch
1.2.2.
Which version of RAP are you using?

Best,
Ivan

Thanks a lot, Ivan
The RAP version I am using is 1.2.0

I will use this patch and try to verify it.
And only update the class of JSLibraryServiceHandler.java?
RWTDelegate.java is not need to update?

Best Regards!

For the needs of bug 298181 only JSLibraryServiceHandler has been
updated, yes.
If you still have problems after the patch, please feel free to open a
separate bug with a snippet to reproduce it.

Best,
Ivan

Thanks Ivan.

I am sorry to say that my RAP application still has the problem after using the patch.

Hi,

did you apply the patch yourself or did you try out the 1.2.2 release?

Regards,
Ben

Hi Benjamin,
Yes, I apply the patch myself.
The RAP version I am using is 1.2.0.
and I have not try to use the 1.2.2 release.
You mean the problem is solved in RAP 1.2.2 and RAP1.3.
I will try to check it in RAP1.3

Best Regards
