[xmlblaster] Release 1.2 fail-safe: reconnected and publishing, but no sync GET possible

[Johann Thomas <johann.thomas at danet.de>]

Hello Marcel,

I have a standalone server node and few clients. I do persistent 
subscribes, publishes and gets (both xpath and oid) and erase, but 
ignore updates (incoming messages).

Seems I have some misunderstandings relating the client queuing: I 
switched to Oracle on client side (not sure it worked), now I tried if 
fail-safe still works, but only publishes work after the restart of the 
xmlBlaster standalone server. The message queued on client side is 
delivered after reconnect, also further publishes work. Also, no 
XB_ENTRIES table is created in Oracle.

At the client side I have configured:
------snip---------
JdbcStorage[Oracle]=org.xmlBlaster.util.queue.jdbc.JdbcQueueCommonTablePlugin,\
 ...\
 entriesTableName=ENTRIES,\
 dbAdmin=true
StoragePlugin[JDBC][1.0]=${JdbcStorage[Oracle]}StoragePlugin[RAM][1.0]=org.xmlBlaster.engine.msgstore.ram.MapPlugin
# avoid meat caching!
StoragePlugin[CACHE][1.0]=${JdbcStorage[Oracle]}
#
QueuePlugin[JDBC][1.0]=${JdbcStorage[Oracle]}
QueuePlugin[RAM][1.0]=org.xmlBlaster.util.queue.ram.RamQueuePlugin
QueuePlugin[CACHE][1.0]=org.xmlBlaster.util.queue.cache.CacheQueueInterceptorPlugin,persistentQueue=JDBC,transientQueue=RAM
JdbcDriver.drivers=\
                  oracle.jdbc.driver.OracleDriver

Client init:
------snip---------------
// ...
 qos.setPersistent(true);
//...
 qos.setSessionName(...);
// Setup fail-safe handling ...
 Address addressProp = new Address(m_oXGlob);
 addressProp.setDelay(4000L); // retry connecting every 4 sec
 addressProp.setRetries(-1); // -1 == forever
 addressProp.setPingInterval(0L); // switched off
 qos.getClientQueueProperty().setMaxEntries(1000); // queue up to 1000
                                                           // messages
 m_oXCon.registerConnectionListener(new I_ConnectionStateListener() {
   // logs events
    ...
 };
 m_oXCon.connect(qos, new I_Callback() {
   public String update(String cbSessionId, UpdateKey updateKey, byte[] 
content, UpdateQos updateQos)
           {
           // ...
                 return "";      
       }
 };
