Arguments
obj 
The object reference to set
val 
The value to store
Further information
1. This will create a Java object to hold the passed value and store its reference within the jvmobject. This reference will automatically be deleted when the model ends, or the jvmobject variable is reset or falls out of scope, or setvalue or setnull is called for this object.
2. When calling setvalue, the jvmobject will be populated with a java.lang.Integer, java.lang.Double, java.lang.Boolean or java.lang.String, depending on the type. To specify a different type, call one of the procedures with the type in the name, such as setshortvalue.
3. When calling setcharvalue, the passed value must be a text containing a single character. The model will abort with a runtime error if the value is an empty string or contains multiple characters.
4. Deletes any reference to a Java object that was previously held by the jvmobject. If there are no other references to the Java object, it may become eligible for garbage collection in the usual Java way.
5. If mosjvm has not yet loaded the Java Virtual Machine into the Mosel process, it will be loaded by this function. If Java cannot be found or an error occurs loading it, the model will terminate with a runtime error.
