No, the container uses the {set|unset}{Session|Entity}Context() callbacks to

Re: EJB referencing in IONA iPortal
Hi Jonathan,
If you're creating an initial context without any properties ensure
that in your container configuration you specify the type
of jndi plug in being used.
Also ensure that your JNDINames.EMPLOYEE_EJB_HOME is
the same as your jndi-name tag in your container configuration.
To use the naming service bundled with the App Server
can set your properties to the following:
Hashtable environment=new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.cosnaming.CNCtxFactory");
// The ORB we want to use is Orbix2000, which is configured below
// to use our iPAS configuration The following two properties are
// usually found in orb.properties, but in case we haven't
// configured our JRE correctly... see
// http://java.sun.com/products/jdk/1.2/docs/api/org/omg/CORBA/ORB.html
Properties orbProperties = new Properties();
orbProperties.put("org.omg.CORBA.ORBClass","com.iona.corba.art.artimpl.ORBImpl");
orbProperties.put("org.omg.CORBA.ORBSingletonClass","com.iona.corba.art.artimpl.ORBSingleton");
// The ORB name dictates the plugins that Orbix2000 will use. The
// ORB named "iPAS" is preconfigured with certain properies, such
// as the ability to propagate security and transaction contexts.
String[] orbArgs = new String[] {"-ORBname","iPAS"};
environment.put("java.naming.corba.orb", org.omg.CORBA.ORB.init(orbArgs,
orbProperties));
InitialContext initial = new InitialContext(environment);
ok,
Maggie

PK Generation and CMP problem
Hi, Sorry if this is vendor specific, but it's an odd one in a not very odd combination : Environment : IAS 4.0, SQL Server 7, NT I have a legacy DB we're wrapping with EJB's etc - C/S - n-Tier The DB has a PK on each table which has the (SQLServer specific?) keyword 'IDENTITY' attached to it. My understanding of this is that it creates a new PK for every insert - which is actually kinda neat as it circumvents the need to generate one ourselves. The problem I have is that IAS, when using CMP, generates code to insert a (null - because it doesn't have a value) value into the PK - but SQL Server doesn't like this and throws an Exception. This (sort of) makes sense as the CMP will not know about the IDENTITY thing and assume we know what we're doing with the PK from within the bean. I'm currently waiting for Inprise to come back on this, but I wondered if anyone had run across this before (or had any suggestions). I can't turn off the IDENTITY as other apps update the DB, and I really don't want to go to BMP as it fits nicely into CMP otherwise. Can I 'hide' the field from the CMP somehow?

RemoteException
Hi all, Well EJB 1.1 has deprecated the use of RemoteException inside the bean impl. Instead we are supposed to throw EJBException for system exceptions. Now what happens when the bean itself is accessing another bean ie bean to bean communication --- in that case the second beans remote interface will be throwing RemoteExceptions. Are we supposed to catch it and throw a EJBException back or just declare that bean 1s method which invokes bean 2s remote method as throws RemoteException.

Re: EJB Trx Isolation seems to conflict with concept of general p urpo se EJB's
Problem: We have several general purpose classes we wish to implement as Stateless Session EJB's. These classes participate in different operations like query/add/update/delete. For each operation we want to specify different isolation levels: query=TX_READ_UNCOMMITTED, add/update/delete=TX_SERIALIZABLE. When we attempt to do this on IBM WebSphere 3.02 we run into the following problem: whatever isolation level was set on the first method invocation of the Trx, the same isolation must be specified on every other method invocation involved in the transaction, whether they are on the same EJB or other EJB's. This seems to include standard EJB API methods like create() and findByPrimaryKey(). Well, if methods like create() and findByPrimaryKey() fall under the same restriction we are essentially restricted to 1 isolation level for that entire EJB. If we want to support different isolation levels for the same functionality we have to write a new EJB for each isolation level. It seems that the concept of code reuse is in direct conflict with current support for EJB Transactions. The EJB 1.0 Spec appears to reinforce (explain) the behavior described above. The EJB 1.1 Spec appears to back away from transaction isolation, addressing issues like above in extremely vague terms. Solutions(?): We can simply not use EJB's when generic classes need to participate in different types of transactions. This is not what we want to do but it works. What I would like to see is a standard for container providers that solves this problem in the following way: when a new transaction starts the container is aware of the specified isolation level and automatically applies that same isolation level to all remaining method invocations in that transaction. I have no idea how difficult this might be for container providers to implement but it would be nice for bean providers in the above scenario. As an alternative, you can write a few deployment descriptors, each with a different transaction isolation level. No need to touch the Java code. You would select the isolation level by the JNDI name of the bean. - Avi -- s/\be(\w+)/e-\1/g; === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".

Re: Dynamic finder method with CMP
Title: RE: Dynamic finder method with CMP Wade et al: We had this same scenario and we chose to use a session bean for the dynamic querying. We found that performance would be heavily impacted by using a CMP entity bean (since you'd have one database hit for the initial find, and then 1 hit for each entity bean that is created). At that point, it came down between a BMP entity bean and a session bean. There wasn't any advantage to creating an entity bean that represented query results, and if anything, it would consume more resources than the session bean approach. A stateless session bean could be used to perform the query and return a business object representing the results, and then thrown away. In general, our pattern is this: When the user is performing an action that will return multiple entities (rows) from the database (and it is typically a small number of attributes for those entities), we use a stateless session bean. When the user is performing an action that will return detailed information about a single entity (row) from the database, we use entity beans. -tb -Original Message- From: Wade Catlyn [SMTP:[EMAIL PROTECTED]] Sent: Thursday, June 08, 2000 6:58 PM To: [EMAIL PROTECTED] Subject: Dynamic finder method with CMP Hi folks, I wish to implement an entity bean that has a findBy method whose search criteria is specified dynamically. This would be useful for operations where a user can specify what criteria he wishes to search by. (e.g an html form with several fields such as name, age, address, date... etc, and the query would be composed using only the fields which the user selects). This can be easily done using bean managed persistence by having a method of the form: findByCriteria(SearchCriteria sc) where the desired query would be composed using the information extracted from the SearchCriteria object. However this would not be possible if container managed persistence is used. Does anyone have any suggestions on how this kind on functionality could be implemented without having to give up the advanteges of CMP ? thanks Wade Catlyn === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message signoff EJB-INTEREST.

Re: PK Generation and CMP problem

Although there are general purpose ways to support this feature in the EJB model (see my posting: Sequence Number Generator for details) it is a frequently enough requested feature that it deserves inclusion in the CMP engine proper. Note that by definition support for this feature goes beyond the scope of the EJB specification. IMO, this is a bug in the EJB spec., but for now, caveat emptor. So, if you have used a particular technique successfully, please let us know. If you think you know how to solve the problem for a particular DBMS, let us know.

My understanding of this is that it creates a new PK for every insert - which is actually kinda neat as it circumvents the need to generate one ourselves. The problem I have is that IAS, when using CMP, generates code to insert a (null - because it doesn't have a value) value into the PK - but SQL Server doesn't like this and throws an Exception. This (sort of) makes sense as the CMP will not know about the IDENTITY thing and assume we know what we're doing with the PK from within the bean. I'm currently waiting for Inprise to come back on this, but I wondered if anyone had run across this before (or had any suggestions).

Re: WebLogic and logging
Weblogic does provide facilities to do the logging, but it doesn't mean you have to use it. I think the original question was: where to find the outputs from printlns inside the bean implementation. if you start the server from script, you should be able to see it from the console where you started the server. From: Douglas Bullard [EMAIL PROTECTED] You have to use one of their classes to do any logging. I'd recommend wrapping this in your own class, so if you move to another appservers (say GS/J) you won't have vendor-specific code sprinkled throughout your code.

Re: Practical JMS usage
Let's say you are creating a user's account and part of that it to create an email account for the new user. The email account will be created by 'someone' that specializes in email and has partnered with your company. You do what needs to be done on your side of things and wait for confirmation of the email account creation. If there is a problem creating the email account (the server is down, the username is taken, ...) you need to be able to rollback the transaction (or deal with it in some graceful manner). This kind of scenario is common and is handled well by a queue, in this case, JMS. You might want to look at 'ACID' and 'two-phase commits'. Scott Durrant Human Genetics University of Utah [EMAIL PROTECTED] On Mon, 12 Jun 2000, Chuck Butkus wrote: You should use JMS if you want to do things "asynchonously". Since you are forbidden to create threads in your beans, you cannot call a method on a bean directly and have it be an asynchronous call. In other words, you will have to wait until the bean has completed its processing. This may include calling other beans, databases, clients, etc. This behavior can be undesirable in many situations where you just want to call the method and have it return before doing any heavy processing, allowing the caller to go on with other tasks. To accomplish this you would either have to create a middleman object to handle the threading issues (not the simplest thing to implement) or use JMS. -Original Message- From: A mailing list for Enterprise JavaBeans development [mailto:[EMAIL PROTECTED]]On Behalf Of Mr. Jake Sent: Thursday, June 08, 2000 2:50 PM To: [EMAIL PROTECTED] Subject: Practical JMS usage Hello, I have been reading a lot about JMS recently, and I was wondering if anyone could share some of the particular ways that they have been using this in practice. It sounds potentially useful, but I'm having a hard time identifying particular instances where this would be of benefit. I am specifically interested in hearing how this would tie in with EJB architecture. I also have two specific questions regarding JMS. First, if you are using it to do something like creating EJBs on the receipt of a message, why is this better than, say, just creating the EJB directly via a method invocation rather than going through the middleman of a messaging system? Secondly, it seems like JMS is geared towards highly distributed systems. We are in the process of building a product which is a hosted service that would need to send messages to customers of ours. On our end, these would be produced using Weblogic. If these messages were sent using JMS, could our customers receive them using a different JMS vendor than Weblogic?

The rows get created/insertedand the remote reference is obtained, but any further calls of the methods in the Remote interface throw a RemoteException : nested exception "NoSuchObjectException" ... digging down further found that the object reference in the handle is "null" No solutions yet, neither any explanations ;-(.

WebLogic and MQSeries
Hi all, My project involves integration of MQSeries with WebLogic server, this mainly makes use of applications already written on the mainframe side, weblogic is used to provide the web interface and do some fancy stuff. I am planning to use MQSeries to send/get talk to Mainframe. Now my questions are: 1. Can I use the JMS interface of WebLogic to connect to MQSeries. 2. What about connection pooling to MQSeries. 3. I will be using BMP entity beans to be created from MQSeries messages, has anyone done this. 4. I want to use XML messages in MQSeries, I read somewhere that MQSeries can convert and pass XML messages. [I know there is another product - MQSeries Integrator, this can convert Cobol Copybooks and C structures to XML], but can MQSeries basic version do some stuff like this.

Re: WebLogic and MQSeries
I can't claim to have worked with WebLogic MQSeries, but having worked with WebSphere and MQSeries, I can give you some input that may prove useful. My project involves integration of MQSeries with WebLogic server, this mainly makes use of applications already written on the mainframe side, weblogic is used to provide the web interface and do some fancy stuff. I am planning to use MQSeries to send/get talk to Mainframe. Now my questions are: 1. Can I use the JMS interface of WebLogic to connect to MQSeries. I suppose so. It should be interesting marrying the WL JMS interface to the MQ Series provider. The biggest problem we found with using the JMS interface with MQ was the 'functional logon' to the mainframe. JMS spec specifies that the username is set by the provider and on a NT machine it is the username of the person who had started the MQ Q manager. This was a pain for us and thus we have temporarily reverted back to the native API to fix the authentication problem. We have our transport layer abstracted so that we can switch between JMS and the MQ native api. The other problem was that for the MQ IMS and CICS bridges, the headers are provided as nice C structures. We have had to reverse engineer them to Java classes. The minor problem here is to fiddle with the provider options to get the right MQ message format sent to the mainframe for the IMS header. 2. What about connection pooling to MQSeries. We are not doing connection pooling to MQ at the moment, but relying on the instance pooling of the application server to perform that function. The beans that do the MQ interface are isolated to the data tier and we know exactly how many and how max they can grow to. 3. I will be using BMP entity beans to be created from MQSeries messages, has anyone done this. We use SSB's. Interesting with BMP beans. Why ? Do your messages follow a relational format ? How will you provide finders etc... ? 4. I want to use XML messages in MQSeries, I read somewhere that MQSeries can convert and pass XML messages. [I know there is another product - MQSeries Integrator, this can convert Cobol Copybooks and C structures to XML], but can MQSeries basic version do some stuff like this. Yes, it can do that and more. But if you are using JMS, just extend TextMessage and supply the XML data. Here is an article that goes to greater detail. http://javaworld.com/javaworld/jw-02-2000/jw-02-jmsxml_p.html -- Aravind === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
