Error calling a submit: java.io.NotSerializableException

Question

There is a Web Panel from where a Call is made to a Procedure as a Submit. The Submit is sent an empty String and a collection SDT as parameter. When it is called, it fails with this error: java.io.NotSerializableException. How can I solve this?

Answer 1

The thrown exception is telling you what is the problem. You need to make the required object to be serializable.
It can be done by implementing java.io.Serializable interface :

class MySerializableClass implements Serializable {}

Now MySerializableClass is serializable and can be used as bean etc.
