About Invoking a Method
Use the following syntax to invoke a method:
{Java_class.method_name(param1, param2, ...)}
where:
Java_class is the path to a Java class with packages separated by a forward slash (/), such as rsdesigner/component/Artifact.
method_name is a static method of that class that returns a void.
If the Java method is not being called from a button, it returns a java.lang.String and certain parameters are automatically passed to the method that is called. The following table defines the parameters for each type of method:
