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´???

It dosn't work with a StringBuffer object. I will get the same error message, I think it was a connection problem - but I don't know what to do?

Cryptography with Orion

Re: Cryptography with Orion
Thanks for your answer. ...and is there a possibility to have a permanent cryptography between the Orionserver and a standalone client over the TCP/IP network? Best regards Tobi -Ursprngliche Nachricht- Von: elephantwalker [EMAIL PROTECTED] An: Orion-Interest [EMAIL PROTECTED] Datum: Montag, 12. Mrz 2001 12:36 Betreff: RE: Cryptography with Orion Orion provides three different concrete objects for user authentication...all use the usermanager interface. EJBUser, DataSourceUserManager and the default UserManager. The default is the simplest, and uses the principal.xml file to define the user name and password. We use EJBUser since it was so simple to add it to our application. As for the actual transmission over the network to the database, that's up to the database/jdbc, but Oracle and others allow encrypted, secure transmissions over the wire, including a local network. As for cryptography...if you are using a https://somesecureurl.company.com , you can certainly encrypt the login transaction from a web page. All three user managers also let you use certificates for authentication. In addition, you can write your own user manager which uses LDAP...and use the various encryption protocols used with LDAP. There's also a hack on the www.orionsupport.com site which allows you to authenticate against your unix/linux users. You might look at the petstore application, and how the orion security adapter is used with this. As for your second line...couldn't quiet figure out your request.

Re: How can I use an BLOB datatype
Hello again, my prog. is very easy. I'm only have a String (contain a big Text) and I will it save on a colmn (Oracle DB) with a BLOB. Thanks Tobi -Ursprüngliche Nachricht- Von: Tim Endres [EMAIL PROTECTED] An: Orion-Interest [EMAIL PROTECTED] Datum: Donnerstag, 30. November 2000 07:10 Betreff: RE: How can I use an BLOB datatype Gernalizing this one step further. We have a situation where we want to place large ( larger than 10MB ) into the DB. Thus, when I get or store I would really like to have an InputStream or OutputStream to read or write the "object". However, it does not appear that EJB really supports this. Has anyone build an entity bean (or session for that matter) that can stream large amounts of data into and out of the database? How? Thanks, tim. In CMP, the output streams should be created for you. The database config xml file should provide a mapping of a Serializable object to a BLOB/Image/etc. If this is done, the object will be serialized before insertion automatically. -tim
