[JBoss Seam] - <s:fileUpload> problem
by jquery＠interia.pl
Hi,
I have a problem with <s:fileUpload> control. As a database I'm using DB2 v.8.2. When the receiving field (generated by seamgen) is a Blob type it gets null after a form is submitted. When the receiving field is Byte[] or byte[] type I get mapping exception during JBoss AS startup:
| javax.persistence.PersistenceException: org.hibernate.HibernateException: Wrong column type: APPENDIX, expected: varchar(255) for bit data
|
When the receiving field is InputStream type I also get mapping exception during JBoss AS startup:
| javax.persistence.PersistenceException: org.hibernate.MappingException: Could not determine type for: java.io.InputStream, for columns: [org.hibernate.mapping.Column(APPENDIX)]
|
A form encoding and Seam Multipart servlet filter are configured as in docs and the DB2 (APPENDIX) field is Blob type.
How can I configure <s:fileUpload> so that it can work properly with DB2?
Thanks in advance for any help.
Best regards,
jquery

[JBoss Seam] - Re: Seam Conversation Should Be Flexible but NOT

Yes, I have read it several times - I want to understand what you want/what your issues so we can try to make your apps work better with Seam. You are using a common paradigm for a user interface - one that you say Seam doesn't work well with.
anonymous wrote : Common I did not say that I need all components in SESSION.
No, you never explicitly stated what scope the components should be in. I inferred from this
anonymous wrote : the application data entry form has to be in the edit mode all the time unless the user want to close the form by clicking on the DONE, CLOSE or whatever... button to get back to the search result page
that you were looking for session scoping from your post.
What scope should your components have? Not in terms of Seam's SCOPEs necessarily, but in terms of user experience.
anonymous wrote : anonymous wrote : neither a very long running conversation timeout or even set it to the same time-out as the HTTP session time out. Standard is 30 minutes, or at least most of my apps.

No, I meant I didn't understand the sentence.
anonymous wrote : Can you look at the conversation stack for a bunch of runaway conversations waiting to be closed?
Yeah. Look at the conversationTimeout method in org.jboss.seam.core.Manager for how Seam times out conversation. You could create an extended version of Manager and implement a custom conversationtTimeout that used an algorithm more suited to your app. The API for this stuff is all public :)
anonymous wrote : A more elegant timeout that coordinates with http session timeout.
Spell out what this means - I haven't understood yet ;) What do "elegant" and "coordinate" mean?
anonymous wrote : I don't want to use conversational session scope, only conversational scope here
Ok, so just to clarify: You don't want to use SESSION scope. You want to use CONVERSATION scope.
anonymous wrote : or no conversation at all by setting the conversation on/off.
What does setting the conversation "off" mean? Normally if you want a scope shorter than CONVERSATION you would use PAGE or EVENT

[JBoss Messaging] - Separate log files no longer works with JBM 3.2
by chip_schoch
When I upgraded to JBM 3.2 recently I had to go back and add:
| <loader-repository>jboss.messaging:loader=ScopedLoaderRepository
| <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
| </loader-repository>
to my jboss-service.xml files on the message processing MBeans I have written, because when I didn't have it I get:
2007-04-17 16:07:17,213 ERROR [com.eLynx.Messaging.MessageReceiver] Exception running MessageReceiver [thread id=155].

I have my log4j.xml configured to log to different files using the TCLFilter:
<filter class="org.jboss.logging.filter.TCLFilter">
| <param name="AcceptOnMatch" value="true"/>
| <param name="DeployURL" value="eLynxFileConversion.sar"/>
| </filter>
Now I do not get any logging to the separate file. It looks like the TCLFilter must be using class loader to determine which archive a class came from? Anyway, it is an unintended consequence of the latest changes.
Any ideas about how to fix this?

[Installation, Configuration & Deployment] - Re: Is there a way to view the size of HTTP sessions in JBos
by thirtybelowzero
I guess by size (though admittedly they may be slightly different) I mean the actual size of the session as stored in memory or on disk.
Here's a little background:
I'm helping to test an application that seems to be storing a large amount of data in the HTTP session. During the test, after a number of login/logout sequences (about 70), we start to see OutOfMemory errors. The Heap size is currently set to 512 MB. If I decrease the session timeout to a very low value (3 min.), and rerun the test, everything works fine and the memory is ok. I interpret this behavior to mean that the session size is getting large (ie. 70 sessions/450M is approx. 6.4 MB per session), and as long as I time them out before the test completes, we don't run out of memory. Since I'm not really accounting for the other processes that may be running, this is probably not a very good estimate, so I'm looking for a way to view these within JBoss to get a better estimate of the actual session size.
