[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by otaylor

Manik: I think using a separate method is likely a cleaner approach. I do want to note here that a separate method by itself can't solve the correctness issues I noted in my comment of Sep. 18th, at least for the pessimistic case, since basically the cache has no way of knowing whether the put() or the update() is providing newer information. In the optimstic case with explicit versioning, the situation is better. Scott: Are you wondering if we can get a "dirty read" if we call putFromExternalRead() the transaction suspended? The assumption here is that the caller of putFromExternalRead() only calls the method with data that was committed to the database before the start of the outer transaction, and not with data that was updated in the outer transaction. Hibernate, for example, makes that guarantee except in the most exotic situations. (You might be able to fool it if you tried hard.)

[JBossCache] - Re: Urgent- Socket error when adding object to DB using JDBC

by manik.surtani＠jboss.com

Fair enough. The problem here though is that when using transactions that span multiple calls, this breaks things. A proper solution would be to use a rudimentary internal pool (HashMap of open conns) for the non-managed factory.

[JBossWS] - How to create Cutom SoapException

by kapil.singhal

Hello, I am creating a Web Service using JBossWS. I want to customize the contents of SOAP Exception, which I want to throw from my Web Service. For this, I am using SOAPFaultException to create my own exception classes. But I am not able to fill the detail in the Detail attribute of the SOAPFaultException. I am filling the specifics of JBossWS using the "org.jboss.ws.soap.SOAPFactoryImpl". But on the client side when I run my RMI Client, I found that one of the element is not Serializable. (Please find the stack below.) Can you suggest me how to fill these so that I can throw a customized SoapFault exception at the client end ? Any help will be appreciated.

[JBoss jBPM] - Re: Task Nodes - conditionally create tasks?

by Olivier_Debels

"cpob" wrote : | Making the change to support the AUTOCREATE column is far simpler than creating an optional task node. All that is needed is the if..statement in TaskNode's execute method and then support for the new column in the mapping/etc. Yep, I agree. I this also useable if you want to create 2 mandatory and 3 optional instances of the same task def? And what if the task def is not defined in a task node? I don't think a ref to task defs is possible. Just wandering if the task/task node link as it exists now can' t be extended. Anyway, I think your solution indeed gives an added value. Thx, Olivier.

[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by manik.surtani＠jboss.com

Yes, but this is deemed acceptable since the cached versions are not deemed true representations of data (in this use case) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977551#3977551 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3977551

[JBossCache] - Re: Urgent- Socket error when adding object to DB using JDBC

by malek256

We are not using transactions. Keeping the connections open and reusable was the intent; our information obtained earlier was that this scenario could not run at all and we needed to use a connection pool - however that does not suit our purpose as it would require significant alteration of the existing code OR use of a JNDI interface plus app server which is 100% against the scope of what we are trying to achieve.

[JNDI/Naming/Network] - rmi traffic

by abv

Hello! I've a rich client that calls session bean methods over rmi. How does the parameter/result objects are transported? Is it done by serialization - transport - deserialization? If it is so, is there a way to use compression to reduce the network traffic? regards Sven View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977547#3977547 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3977547

[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by Scott.Marlow.Novell

Regarding #1, if we suspend the active transaction at cache put time, wouldn't JBC send cache changes too early (before the suspended + later resumed tx completes?)
