[JBoss-user] [Clustering/JBoss] - stateless session bean communication over http / internet
Hi, is it possible to run a JBoss cluster over the internet? In particular, this is what I want: On server A I am running Stateless Session Bean 1. On server B I am running Stateless Session Bean 2. Now I want to let SLSB 1 communicate with SLSB 2. However server A and B are NOT located on the intranet, but can only communicate through the internet. In other words: 1. The JNDI lookup of SLSB 1 to find SLSB 2 need to occur over the internet. 2. Moreover, the communication between the SLSBs, which happens to be RMI/IIOP should tunnel through HTTP and should cross firewalls. Does any one know if this scenario is possible?

[JBoss-user] [J2EE Design Patterns] - Who can help with design challenge to get data from Session
Hi, I'm working on a J2EE application with Servlets and EJBs. One of the tasks is to do a big calculation (10 min-1 hour). In order not to use all CPU resources for these calculations, I have an asynchronously design pattern and do the calculations one by one. To this end I use a Servlet that sends a message with Java Message Services (JMS) to a queue. A point-to-point Message Driven Bean is pulling messages from the queue and is subsequently calling a Session Bean that does the calculation. Until so far, this obeys EJB Design Patterns of Floyd Marinescu, Chapter 1 ,Message Facade. Here comes my question: The results of the calculation, once the calculation is finished, are sitting in the Session Bean (in memory). Now I want to access the calculational results of the session bean from within a servlet. How can I do this? In some way the data in the session bean should be associated with a user session of the servlet. But I think I can not access session attributes of the HttpSession nor those of the ServletContext. By the way, I don't want to persist them in a database because it 's a lot of data and it's not clear whether data is needed in the future. This is undoubtly an issue that occurs in more applications. Can someone help me with this one?

[JBoss-user] [Persistence CMP/JBoss] - Re: blob CMP MySQL EJB JBoss3.2 mapping problem
If you say default mapping I suppose you mean the one in
jboss-3.2.2/server/default/conf/standardjbosscmp-jdbc.xml, right?
Well I also had problems with the default mappings for timestamp/datetime. None of the
listed mappings worked for me.
However, what worked for me is:
JAVA Sql type: TIMESTAMP
Vendor type: datetime (in Mysql)
CMP field: java.sql.Timestamp
which was arranged by my IDE.
If i'm correct this mapping is not in
jboss-3.2.2/server/default/conf/standardjbosscmp-jdbc.xml. This one only contains:
| java-typejava.sql.Timestamp/java-type
| jdbc-typeTIMESTAMP/jdbc-type
| sql-typeTIMESTAMP/sql-type
| !--
| | This type is problematical because mysql does not have any
| | date/time types that store milliseconds. You should avoid it.
| --
|
|
| java-typejava.util.Date/java-type
| jdbc-typeTIMESTAMP/jdbc-type
| sql-typeDATETIME/sql-type
| !--
| | Note that you lose granularity here
| | Use a numeric type and store milliseconds if you really need it
| --
|
|
| java-typejava.sql.Date/java-type
| jdbc-typeDATE/jdbc-type
| sql-typeDATETIME/sql-type
|
|
| java-typejava.sql.Time/java-type
| jdbc-typeTIME/jdbc-type
| sql-typeTIME/sql-type
|
|
|
| As far as BLOBs are concerned, in file
jboss-3.2.2/server/default/conf/standardjbosscmp-jdbc.xml you have the mapping
|
|
| | java-typejava.lang.Object/java-type
| | jdbc-typeBLOB/jdbc-type
| | sql-typeLONGBLOB/sql-type
| | !--
| | | Change this from LONGBLOB to BLOB if you know your
| | | serialized object will be = 2^16 bytes
| | --
| |
|
| This one doesn't work for me. JBuilderX makes a scheme from the DB as follows:
|
| JAVA Sql type: VARBINARY
| Vendor type: blob (in Mysql)
| CMP field: byte[]
|
| When I use this it doesn't work either.
|
|
|
| The mapping done by the IDE is based on the driver, which is confirmed by the
MysqlDefs class from Mark Matthew's driver (the official one now):
|
|
| Maybe I am misuderstanding something fundamentally.
|
| Any help would be highly appreciated.

[JBoss-user] [Persistence CMP/JBoss] - Re: CMP, BLOBS and findAll
Hi, I can tell the following on Read-ahead strategies. By default a find-method returns only the primary keys of the records from the DB. (SELECT PK FROM TABLE T; is carried out). Once you invoke a method of a single CMP-EJB (from the collection you got from the find-method) the remainder of the record is retrieved. (Eg. SELECT * FROM TABLE T WHERE PK=2; is carried out). By setting read-aheadon-find/read-ahead in combination with a eager-loading group name, the find method returns besides the PK all fields defined in the group-name. (Eg SELECT PK, FLD_A, FLD_B FROM TABLE T; is carried out when the find-method is invoked, where FLD_A and FLD_B are elements of the load group.) Below a sample of jbosscmp-jdbc.xml with load-groups. The read-ahead strategy can be set on bean level, but also on finder-method level. So, if you've used a read-ahead strategy of on-find by default, the none read-ahead strategy at finder-level will overwrite other read-ahead strategies. I hope this will help. I hope you can give me some help in return: I use JBoss3.2 and MySql4.0 and CMP. I have difficulties with reading BLOBs. Can you tell me what mapping I need to use? The mapping java-typejava.lang.Object/java-type jdbc-typeBLOB/jdbc-type sql-typeLONGBLOB/sql-type doesn't work for me. Or do I need to do something with a serialized object. Hope you can give me a piece of code.

[JBoss-user] [EJB/JBoss] - Compound PK DeploymentException
Hi everybody,
I have question concerning compound primary keys in CMP2.0 EJBs.
I've got a deployment error: Generation only supported with single PK field from
Jboss 3.2.2 (See below).
What do I do wrong?
Do I need to configure someting in JBoss in addition?
My codes and xml-pieces for a vey simple test-bean (A) with corresponding DB table
(a) are listed below.
I appreciate any help.
Thanks,
Evert Bende
PS:
The PK-class was generated by Borland JBuilderX.
My table is stored in a MySQL database.
None of the pks in table a are auto-incremented.
I also tried it with a create statement with a single argument, like ejbCreate(APK
apk){...}, but this didn't work out either.
