Jabber and Orion
Has anyone tried Jabber with Orion? what is your experience? Hadi Jabber is an instant messaging server similar to ICQ..., completely built on XML www.jabber.org
JMS for non-java clients !!
hi, is it possible to use the JMS Server with non -java applications as JMS Clients? (both pub/sub & p2p) Hadi
Orion tries to use more connections that the maximum # of connections that are allowed! Why?
If I use Orion's connection pool with a database that has only a few connections (5-10) and I explicitly define it in the data-sources.xml file Why do I get error messages saying that the maximum number of applications is already connected to the database. " 2001-04-05 15:16:30,012 ERROR [ApplicationServerThread] (Controller.java:87) - com.evermind.server.rmi.OrionRemoteException: javax.ejb.EJBException: Error saving state: [IBM][CLI Driver] SQL1040N The maximum number of applications is already connected to the database. SQLSTATE=57030; nested exception is:javax.ejb.EJBException: Error saving state: [IBM][CLI Driver] SQL1040N The maximum number of applications is already connected to the database. SQLSTATE=57030 " as I understand the connection pool, Orion should not use connections if the maximum allowed is already in use? could someone explain me Orion's Connection pool with a limited database(limited number of conections) Thanks Hadi

RE: Help: deadlock with concurent access to entity bean
Storing Images works for me using DB2
it should also works with DBs supporting BLOB
1) first check that your db schema config file defines a mapping between
java.io.Serializable and BLOB
2) implement a Picture class that implements
Serializable
--->
public class Picture implements Serializable {
public Object data;
public Picture(){}
public void setData(byte[] data) {
this.data = data.clone();
}
public byte[] getData() {
return (byte[])data;
}
}
3) in your bean declare your picture as an instance of Picture class and
deploy it as a container
managed field
Hope it'll work for you
As you read it in my previous message, I'm facing deadlocks with a heavy
concurent access to PictureBean
I'm still searching for a solution

Error in ejbLoad : java.lng.AbstractMethodError:

Nested exception is:

my entity bean contains [ id(int) + array of bytes to hold the picture]
the table [id + Blob]
my code in ejbLoad :
Context ctx = new InitialContext();
DataSource datasource = (DataSource) ctx.lookup("jdbc/DefaultEJBDS");
conn = datasource.getConnection();
ps = conn.prepareStatement("SELECT photoImage FROM photo WHERE photoId=?");
ps.setInt(1, id);
rs = ps.executeQuery();
if (rs.next()) {
String colName = "image";
Blob blobObj = rs.getBlob(colName);
if (blobObj == null){
System.out.println("[PhotoBean|ejbLoad] Error creating Blob object -
Blob
object is null");
}else{
int imgSize = (int)blobObj.length();
// Create byte[] data array to store picture data temporarily
// before writing it to a file
image = new byte[imgSize];
// Retrieve the picture as a binary stream from the Blob object
InputStream is = blobObj.getBinaryStream();
// Store the binary stream from above into image byte[] array
is.read(image);
}
}
db2.xml schema:

In the beggining I was afraid that JDBC driver for DB2 doesn't supports
blobs
but the same code works often just after the insert of the picture in
DB(???)
How do I fix this? Any clues?
