To recap, the GWT-RPC protocol allows the exchange of custom Java objects. If the classes are missing for the sent Java objects, the request binary data cannot be decoded for conversion to XML. The following procedure explains how to resolve the problem of missing Java classes.
Information: With GWT, an object is said to be serializable when it implements the java.io.Serializable interface (from GWT 1.5 onwards) or the com.google.gwt.user.client.rpc.IsSerializable interface (for earlier versions).
Information: For NeoLoad to be able to decode the GWT requests and responses, the following elements are required: the RPC services client interfaces, the objects exchanged between the server and client and the other referenced classes.
To record GWT requests
When you close the browser, the Post-Recording Wizard is displayed.
Select the JAR files containing the missing serializable Java classes.
Repeat the operation as many times as is necessary.
When all the required JAR files have been declared, a confirmation screen is displayed.
