For NeoLoad to decode the GWT requests and responses into XML, the required libraries must be declared. Required libraries are:
Java objects that are transmitted over the network between client and server using GWT-RPC
The interfaces of the services called by the client application using GWT-RPC
GWT-RPC serialization policy files
Information: GWT libraries can be drag-and-dropped from the file explorer into the declared libraries table.
To declare one or more GWT libraries
Click the + button, and select the WAR file or the directory of the Web application being tested. NeoLoad automatically retrieves all the required JAR and GWT.RPC files. You may also manually select the JAR and GWT.RPC files used by the GWT applications being tested.
NeoLoad automatically repairs any GWT requests flagged as incorrectly converted to XML.
If the repair fails, you can find further information on the error in the relevant plugins.log.XXX log file (the logs directory can be accessed through Help > Open logs folder).
