[JBoss Seam] - Re: Accessing Enum with EL

by pete.muir＠jboss.org

EL doesn't support accessing enums like that. You would need to write an EL function I think. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116888#4116888 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116888

You need to update your components.xml to Seam2 schemas, see the seam2migraton guide View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116887#4116887 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116887

So why did the jboss folks remove the warning from the docs? Not sure why either indeed. I suspect this got lost when the old IPC page got merged in the new Portal API chapter... but this needs to be checked.

[JBoss Seam] - Re: Maven2 example application for Seam2

by pete.muir＠jboss.org

Yes, I don't like the -all.jar s particularly, however I don't see a nice way around it (Seam's deps are different than those in the -all.jar) However, this will all go away when we can target JBoss AS 5 with Seam (as this is what Embedded is based on, and so we can sync jar versions easily). This should be soon. I don't know how to order the classpath with Maven (it's easy with ant) but you need to make sure the -all jars come before everything else when running tests.

[Beginners Corner] - Parallel processing in a JBoss app?

by ohako

Hi there, Sorry if this is covered elsewhere (my Google skills are weak), and for not using ten-gallon words like 'application resource' and 'management interface' (I'm really a moron, y'see). I'm trying to launch an independant thread to do some work from inside an application servlet. In specific, I need to send emails to peopleafter they perform certain actions, but the priority of the email work is less than the priority of actually showing users stuff on my webpage. So, threading. This thread here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4007686 details someone else's take on the same question, and of the stern warnings the JBoss over-people made about the methods being used therein, and of the legal wrangling behind a certain JSR proposal, etc. etc. My two questions: 1. The last post from this thread was in June of '07. I'm using JBoss 4.2.2 GA 'out of the box'. Has something changed here since then? 2. Am I completely barking up the wrong tree, while there's a simple and elegant solution to managed threaded processes that's dangling just behind my crappy skills at Googling this site? Thanks in advance all you experienced JBossers out there! -------------- Ohako View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116884#4116884 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116884

[JBoss Seam] - Re: Maven2 example application for Seam2

by cory_prowse

Yup you are correct, and I have enabled the option to create Java5 bytecode in the parent pom. <plugin> | <groupId>org.apache.maven.plugins</groupId> | <artifactId>maven-compiler-plugin</artifactId> | <configuration> |  | <source>1.5</source> | <target>1.5</target> | <maxmem>1024m</maxmem> | <optimize>true</optimize> | </configuration> | </plugin> It still seems to be at the moment that the problem is those uberjars of "all" dependencies. Having the same class in more than one jar annoys the classloaders (cos they are not the same class then). I could go through and create exclusions for all jars in those uberjars but then the final EAR for a production (or integration test) deployment would be without them as well.

[EJB 3.0] - EJB 3.0 Persistence with Parent/Child and composite keys

by jseriff

I have a fairly common scenario which I am having trouble getting to work as I expect. I have searched through the documentation and forums, but have not yet found any information which helped be with my issue. I have two tables, lets call them PARENT and CHILD in a MySQL database. | ------------------ | | PARENT | | ------------------ | | PARENT_ID (PK) | | | <attributes> | | ------------------ | | ------------------ | | CHILD | | ------------------ | | PARENT_ID (PK) | | | CHILD_ID (PK) | | | <attributes> | | ------------------ | I also have entity classes for these two tables - | @Entity | @Table(name="parent") | public class Parent implements Serializable { | @Id | @GeneratedValue | @Column(name="parent_id") | private int parentId; | | @OneToMany(cascade={CascadeType.ALL}) | @JoinColumn(name="parent_id") | private List<Child> children; | | //getters,setters,etc. | } | | @Entity | @Table(name="child") | public class Child implements Serializable { | @EmbeddedId | private ChildId childId; | | //getters, setters, hashCode, equals, etc | } | | @Embeddable | public class ChildId implements Serializable { | @Column(name="parent_id") | private int parentId; | | @Column(name="child_id") | private int childId; | | //getters, setters, hashCode, equals, etc. | } | So far, this seems pretty straight forward, and I believe gives me what I want. If I create a new Parent object, add child objects and merge, it appears to save, although in a strange fashion. (Note: I am using merge, as in the general case, these may or may not be new objects). The (paraphrased) SQL which is generated using hibernate is - | insert on PARENT. | insert on CHILD set PARENT_ID = 0 and CHILD_ID = <correct child_id>. | update on CHILD set PARENT_ID = <correct parent_id> and CHILD_ID = <correct child_id> where PARENT_ID = 0 and CHILD_ID = <correct child_id> | This does appear to get the job done, but I run into a major problem when I try to insert two parent_ids where child_id has the same value. For example, if I have a Parent1 with a Child1 and a Child2 and a Parent2 with a Child2 (different object, same CHILD_ID) and a Child3 I get the following statements (paraphrased)- | insert on PARENT. | insert on PARENT. | insert on CHILD set PARENT_ID = 0 and CHILD_ID = 1 | insert on CHILD set PARENT_ID = 0 and CHILD_ID = 2 | insert on CHILD set PARENT_ID = 0 and CHILD_ID = 2 (not sure why this doesn't fail... i believe its done via a batch insert?) | insert on CHILD set PARENT_ID = 0 and CHILD_ID = 3 | update on CHILD set PARENT_ID = 1 where PARENT_ID = 0 and CHILD_ID = 1 | update on CHILD set PARENT_ID = 1 where PARENT_ID = 0 and CHILD_ID = 2 | update on CHILD set PARENT_ID = 2 where PARENT_ID = 0 and CHILD_ID = 2 | update on CHILD set PARENT_ID = 2 where PARENT_ID = 0 and CHILD_ID = 3 | It then throws an exception because the update expected to change one row, and it changed none (the third update statement has no effect). I am using JBoss 4.2 and SEAM 2.0 out of the box. I am not clear what I am doing wrong. I assume that the insert with parent_id is 0 is because there is no parent_id set on the child object. I would also assume that the persistence manager would be responsible for setting this after the parent objects are inserted. I would prefer not to have a backwards reference from the child object back to the parent object, as this seems redundant, and will never be used in this context. Am I missing an annotation, or annotation parameter somewhere which will get me the expected behavior? (I would expect to see only 2 parent and 4 child inserts, with no updates at all). Am I forced to flush the persistence manager between each merge(parent) call?
