Re: [JBoss-user] Commit Option A and ejbCreate [auf Viren geprüft]
I am doing all of the object creation inside a single transaction as far as I know, by running inside a SLSB with RequiresNew as the Transaction type. The transaction type of ejbCreate is Requires, which won't create a new transaction will it? I suppose I could change it to Supports? I've never been forced to use ejbPostCreate for CMR setting before, although I have done it that way in the past. I'm currently using androMDA to do code generation, and I generally leave the CMRs out of my EJB create methods. I'll be putting a bug in on this one as soon as I get a spare moment and can write a very small program that demonstrates the bug. -Neal On January 22, 2004 05:19 am, Jonathan.O'[EMAIL PROTECTED] wrote: > Neal, > What are the transaction types for the ejbCreate(), the > ejb.setRelatedItem(item) and the calling method?

Hi Heiko, Thanks for reply. Please bear my ignorance. Could you give a more detailed explanation? Did you mean writing a seperate class and deploy it as a '-service.xml' file. If then, how can I schedule this class to be run, say every 5 mins?

Re: [JBoss-user] jboss.net: How can I modify the service name displayed in WSDL?
Rob The @jboss-net.web-service tag has a parameter "urn" which can be used to set the service name something like: * @jboss-net.web-service * urn="MySessionService" * expose-all="true" -jason On Jan 23, 2004, at 8:35 AM, Rob Moore wrote: I am using the jboss.net xdoclet task and have not been able to figure out how to modify the value that the jboss.net/axis services display for the service name of my session bean.

[JBoss-user] PostgreSQL and foreign keys
Hi, I'm desperately trying to get JBoss and PostgreSQL working together with foreign keys. I'm using JBoss 3.2.3 and PostgreSQL 7.3.4. I want to map the following two tables: CREATE Table kv ( pkey serial not null, kvid int2 not null, nummer integer not null, passwort varchar(63), patientanzahl int2, pzf int2, daz int2, CONSTRAINT id_kv UNIQUE (kvid), CONSTRAINT pk_kv PRIMARY KEY(pkey) ); CREATE Table teilnehmer ( pkey serial not null, teilnehmer_id integer not null, fk_kv int4, firma varchar(255), nachname varchar(255), vorname varchar(255), titel varchar(63), anrede int2 , strasse varchar(255), plz varchar(255), ort varchar(255), mail varchar(255), telefon varchar(255), fax varchar(255), CONSTRAINT id_teilnehmer UNIQUE (teilnehmer_id), CONSTRAINT pk_teilnehmer PRIMARY KEY(pkey), CONSTRAINT rel_teilnehmer_kv FOREIGN KEY (fk_kv) REFERENCES kv (pkey) on delete cascade ); Do you have any hints for me? And please be kind and do not answer "google is your friend" or similar. I searched not only on the mailing list archive but in the forums and the whole web. ;) I think I'm confused with how to do this because of the different JBoss versions (when searching for help in the JBoss persistence forum e.g.) and workarounds posted for them. For clarity I uploaded my two beans and their dds here: http://www.user.fh-stralsund.de/~sestgran/temp/ Can anyone help me on this issue? I can't get it to work correctly.

RE: [JBoss-user] Garbage Collector: Service?
It is my understanding there is little point in an arbitrary GC call. Periodic GC calls have some benefit in terms of distributing effort over time however that is already available through JVM options. That memory shoots up is not relevant unless and until there is insufficient memory to satisfy an allocation request. At that point the GC will run and all threads are suspended within the JVM so no allocation request will occur. The GC will run as often as needed to satisfy the need for additional memory. Out of memory will occur if and only if there are indeed to many reachable references that cannot be released. I would add that the heap is divided in two so that you can run out of the so-called eden space and that can be adjusted using the JVM memory switches. Seems to be a common misconception that forcing a GC will cure out of memory problems. If anybody has knowledget that contradicts this by all means post it since this seems to be an area of frequent concern. Kind of off-topic AFA JBoss is concerned however. -Original Message- From: Muraly R [mailto:[EMAIL PROTECTED] Sent: Thursday, January 22, 2004 9:42 PM To: [EMAIL PROTECTED] Subject: [JBoss-user] Garbage Collector: Service? Hi Gurus, Is there any particular service available in JBoss to schedule the garbage collector? The reason for this question is our application is using heavy weight objects like Vector, HashTable, etc. heavily. As a result of this after a simple get query the JBoss memory shoots up and it is not returning to is normal state. Hence this query. Also, for SessionBeans(Stateful/Stateless), if the is configured as follows: 50 100 600 600 300 300 400 60 1 0.75 and if the ejbRemove() of the corresponding beans are populated with code to 'null' the object will this help.
