Re: big text in string as object over the network: very strange?
I think the specification has declareted this but orion support the BLOB under CMP. See the database schema oracle.xml: type-mapping type=java.io.Serializable name=blob / this entry is a default! -Ursprüngliche Nachricht- Von: Simon Evans [EMAIL PROTECTED] An: Orion-Interest [EMAIL PROTECTED] Datum: Donnerstag, 21.

CMP Entity beans do not support CLOB and BLOB fields...neither 1.1 or 2.0 EJB Specification. you will need to use a Bean Managed Entity Bean and use the JDBC API with CLOB and BLOB. You save them and retrieve them as Streams rather than objects. -Original Message- From: Metla, Suri [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 21, 2001 9:48 AM To: Orion-Interest Subject: RE: big text in string as object over the network: very strange?

Very strange Okay, now I want to create a entity bean which have as attribute a object(this object have a only StringBuffer() object). The create method of the entity will be access from a session bean(in the same apps). The client have access on the session bean. If the session bean call the create method of the entity and the StingBuffer is small it will work. If the StringBuffer() containts a String about 200 KB it throws the message javax.ejb.CreateException: Error creating EntityBean: E/A-Exception: Connection reset by peer: socket write error If the String is bigger than 600 kb I will get the Message: com.evermind.server.rmi.RMIConnectionException com.evermind.server.rmi.OrionRemoteException: Disconnected: Disconnected WHAT HAPPENS´??? I HAVE NO ANSWER HOW I CAN GET IT TO WORK! THANKS! Tobi -Ursprüngliche Nachricht- Von: Tobias Streckel [EMAIL PROTECTED] An: [EMAIL PROTECTED] [EMAIL PROTECTED] Datum: Donnerstag, 21.

What kind of variable is used in the Entity Bean to save the File. Is it a java.io.File object? Thanks a lot by Tobi
