Deployement of RAP application on Apache Tomcat [message #1367169]

Hi everyone,

I have difficulty to deploy my Eclipse RAP application on Apache Tomcat server. One Java Class is not present. In the catalina logs I have this error:
java.lang.ClassNotFoundException: org.eclipse.rap.rwt.internal.lifecycle.RequestCounter

I try to integrate this class in the war product, but it is not in the RAP target platform. I can't find it in the platform.

Is it a usual problem ?
Should i try to force the integration of this class in the war product ?

I use:
Eclipse Plateform 4.3
Eclipse for RCP and RAP developers 2.0
RAP target plateform 2.1
WAR product tooling 0.3
Java 7
Apache Tomcat 7.0

Someone has an idea ? Crying or Very Sad

Hi,
check your target platform and WAR product configuration. Also check
your WAR file if all bundles are present.
HTH,

I can't integrate them directly in the war product, but they are in the war file.
In fact when looking further to the error, it says:
SEVERE: ClassNotFoundException while loading persisted sessions: java.lang.ClassNotFoundException:
Does it means it tries to load previous state of the workbench ?

Because I can see that the workbench is creating (I have the typical RAP grey background displaying), but it's stopping just before displaying the window.
Maybe it is because he is trying to load a previous instance of my workbench.
Should I put an argument like: -clearPersistedState in the War file ? in that case, how and where ?

In which browser did you try? Are you using RAP 2.0?

Yes I am using RAP 2.1.

I was on windows 7 and I switch to Linux (Ubuntu) to run a similar local Apache Tomcat 7 server and I have the same problem.
On Google Chrome: only the background of my software display, but I test the RAP demo workbench and it displays.
On Firefox: My software and the RAP demo workbench both don't work displaying the grey background.

Hi,
in Firefox (if version 29+) you are running in this bug:
433179: RAP application does not start in Firefox 29
https://bugs.eclipse.org/bugs/show_bug.cgi?id=433179
It's fixed in RAP 2.3M3 and there is a workaround for older RAP versions
here [1].

Today I tested the latest Libra WAR Products (0.3.1.201405141436) with
RAP 2.3RC1 and the exported WAR (Controls Demo) works fine in Tomcat
8.0.3. Please enable OSGi console in web.xml and post the output of "ss"
command.

... I am a bit ashame to say that I found the error ...

I totally forgot to include my icons in the plugin build.. So of course it was not able to create Views because at one point I was loading an image, and it was returning a NullPointerException.
I finally realized that when I finally look to the eclipse .log in the work folder of Tomcat. I didn't know that the stdout of eclipse RAP are bind to stdout of Tomcat, but not the stderr. This error was hidden from me as I was only checking the output of Tomcat server.
Sorry for the rookie mistake!

I switch at the same time to RAP 2.3 and it is working now both on Chrome and Firefox.
Thanks a lot for the advise!!! Smile
