[JBoss Seam] - Performance: @Name and @Stateless

by DiegoCoronel

Hi, im using seam generator and my system is really big, im using jboss 4.2.1 and seam 2.0 RC1, im with performance problems , all my beans are just with @Name and i want to know if i use @Stateless is better to increase performance ?? My navigation is taking 15 seconds per page. Im using drools too. I used a breakpoint in my bean constructor and saw that it is stoping for each method im using in my page. I tried @Scope (Sco..Type.EVENT) but its still stoping in constructor class... even if my search come back to same page... ill really apreciate if you guys help me about this problem. Sry about my english.. and congratulations about seam.. im loving this idea.

[JBoss Seam] - Re: #{conversationList} appears to be empty

by jacob.orshalick

It looks like you may have conflicting versions of jars (or at least expected versions). The method Namespace.entrySet no longer exists in Seam 2.0.0.CR1. What version of Seam are you using?

[JBoss Seam] - seam generate-entities error....

by minamti

This scenario seems to create create table groups ( group_id integer NOT NULL AUTO_INCREMENT, group_name VARCHAR(100) NOT NULL, group_desc VARCHAR(100), PRIMARY KEY(group_id)); insert into groups (group_id, group_name) values(1, "admin"); insert into groups (group_id, group_name) values(2, "others"); create table user ( user_id integer NOT NULL AUTO_INCREMENT, group_id NOT NULL DEFAULT 2, user_name VARCHAR(100), PRIMARY KEY(user_id), FOREIGN KEY (group_id) REFERENCES group(group_id) ON UPDATE CASCADE ON DELETE RESTRICT); I seem to get a Caused by org.hibernate.PropertyValueException with message: "not-null property references a null or transient value: com.foo.entity.User.groups" Thanks, M View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090380#4090380 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4090380

[JBoss Seam] - Re: Semantics of @Name, @DataModelSelection

by jacob.orshalick

Sorry, the factory method in the above snippet should read, ... | @Factory(value="person") | public void loadPerson() { | if (pid != null) { | person = (Person) em.find(Person.class, pid); | } else { | person = new Person (); | } | } | ... No value should be passed into the loadPerson method.

[JBoss Messaging] - Re: Clustering appears okay, but no clustered messages

by fuzzybinary

Probably not a UDP problem since I've checked that JGroups is actually working through the examples provided on the wiki, but I think it may be a network config problem somewhere. I changed log4j to TRACE for the examples and the connection to the IP is being refused. I have discovered that I should be using port 1100 (because I'm using HAJNDI), but even with that change, connection is still refused. I have to figure out exactly what that's happening, since netstat shows that 1100 is actually listening for connections.

[JBoss Seam] - Re: Semantics of @Name, @DataModelSelection

"djfjboss" wrote : I had also assumed that the setPid method would be invoked via the edit link and thereby set person to the appropriate entity via the id, but this method isn't even called for me. The fact that the RequestParameter annotation is commented out is a little disconcerting. The pid attribute will not be set unless you uncomment the @RequestParameter annotation (which will directly inject the value) or add an entry in your pages.xml which will call your set method such as, | <pages> | <page view-id="/person.xhtml"> | <param name="pid" value="#{manager.id}"/> | </page> | ... | </pages> I also do not see where fan is being outjected to the page so I don't know where your id would be coming from. Are you providing a list of persons and then the user can edit a person from the list? If you are looking to achieve a RESTful URL here (which is the only reason I could think of for doing it this way), an easier way to accomplish this would be... @Stateful | @Name("manager") | public class ManagerAction implements Manager { | | @RequestParameter | Long pid; | | @In (required=false) @Out (required=false) | private Person person; | | @DataModel | private List <Person> fans; | | @Factory(value="person") | public void loadPerson(Long pid) { | if (pid != null) { | person = (Person) em.find(Person.class, pid); | } else { | person = new Person (); | } | } | ... | Also note that you will not be in the same conversation when the Person is loaded because you are using a general link <a href ...>. Any conversation state will not be propagated. Hope that helps.

[JBoss Seam] - Re: Entity Injection question

by jacob.orshalick

In the scenario you describe, the only time an entity is going to be automatically created is if it is a named Seam component and it has the annotation @AutoCreate. Is this how your entity is annotated? ... | @Entity | @Name("someEntity") | @AutoCreate | public class SomeEntity { | ... Otherwise you would have to have a factory method somewhere... @Factory(value="someEntity") | public SomeEntity initSomeEntity() { | return new SomeEntity(); | } You have to specify when Seam should create instances of components. As far as the following code... | public void submit() { | if (someEntity.someProperty != null) { | log.debug("Entity's Property IS NOT NULL"); | else { | log.debug("Entity's Property IS NULL"); | } | } This code is necessary depending on what you're doing. If you performing validation this could actually be done through <s:validate> or <s:validateAll> and use of @NotNull on your entity attribute. Hope that helps.

[JBoss Seam] - Re: How to Extend Persistence Context Programatically

by pete.muir＠jboss.org

An SMPC is equivalent to an extended persistence context for conversationally scoped components. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090366#4090366 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4090366
