Serializable Check

Belongs to following categories: Utility, ULC5.2,

Purpose

Implements a helper class that checks at runtime if the current ULC session is serializable. This information can be useful when an ULC application is or will be deployed in a Servlet or EJB container.

Resources

Try out the lookup sample as JNLP application or Applet application.

How to use

We call the execute() method of the SerializableCheck class.

SerializableCheck.execute()

How it is implemented

We try to serialize the current ULC session into a byte array using the standard Java Serialization mechanism. An exception will be thrown if the session cannot be serialized.

public class SerializableCheck
{
  public static void execute()
  {
    try
    {
      ULCSession ulcSession = ULCSession.currentSession();      ObjectOutputStream objectOutputStream = new ObjectOutputStream(new ByteArrayOutputStream());
      objectOutputStream.writeObject(ulcSession);
      objectOutputStream.flush();
      objectOutputStream.close();
    }
    catch(IOException ioe)
    {
      System.err.println("Could not serialize session: " + ioe);
    }
  }
}

Compatibility

The described functionality has been developed and tested using JDK 1.3.1_10 and ULC 5.2.
