Exception : Failed to get the SerializationPolicy

[Palak Raval]

Hi,

I have configured openkm project,and using OKMUtils-4.0(download from http://openkm.com/) and also i have included
gchart-2.2.jar,
gwt-incubator-20100204-r1747.jar,
gwt-log-3.0.1,
gwt-user.jar,.
gwt-servlet.jar,
gwt-dev.jar,
gwt-dev-windows.jar in classpath.

I compiled the GWT source successfully and deployed over Jboss 4.2.3 GA After that I am able to login and traverse through the application but the following error is shown on server logs.

Code: Select all

Please do help me.I am assuming that it is a compatibility issue of GWT jars if yes please let me know whether my assumption is correct or not and give me better solution for this.
Thanks in advance

I must suppose you've readed and done the passes described in http://wiki.openkm.com/index.php/Developer_Guide no ? The only problem could be developer guide is focused in 5.0 and could be some change with 4.0 ( but are minors if exists ).

1- Don't try the debugging methods detailed in developer guide ( are only for 5.0 )
2- Have you registered libraries present in ext-libs using the script ?

remove all classes you've included manually you don't need it, simply run the script, in case you're in windows, simply execute in your console each line ( you must have maven installed ).
gchart-2.2.jar,
gwt-incubator-20100204-r1747.jar,
gwt-log-3.0.1,
gwt-user.jar,.
gwt-servlet.jar,
gwt-dev.jar,
gwt-dev-windows.jar

3- Make a clean / and package after it.

4- Ensure OpenKM.war file ( from default sourceforge installation has been removed )
