[JBossCache] - Re: write lock timeout, but no transactions and async replic

by manik.surtani＠jboss.com

Multiple threads reading from and writing to the same cache. You don't necessarily need a TM for this - you can tell by looking at the lock owners - they're Threads, not GlobalTransaction instances.

[JBoss Seam] - Beginner Question

by drab

Hi, I'm trying for a few days now to get the most basic things to work with Seam, but I fail miserably. I'm highly frustrated and of course try to find the missing piece of information here that I'm apparently lacking to get this to work. I created a project with seam-gen and added a page register.xml that contains this: | <h:form id="registerForm" rendered="#{userRegistration.account==null}"> | | <h:outputLabel for="realName">name:</h:outputLabel> | <h:inputText value="#{userRegistration.account.realName}" size="30" id="realName"/><br/> | <h:outputLabel for="email">email: </h:outputLabel> | <h:inputText value="#{userRegistration.account.email}" id="email" size="30"/><br/> | <h:commandButton type="submit" value="register" action="#{userRegistration.register}"/> | | </h:form> | | | <h:form id="otherForm" rendered="#{userRegistration.account!=null}"> | you have been registered as #{userRegistration.account.realName}. You should receive an email with your password. | </h:form> | | I have my LoginAccount entity: | @Entity | @Name("LoginAccount") | public class LoginAccount implements Serializable { | | | @Id | @GeneratedValue | protected int id; | protected String realName; | @Email | protected String email; | | public LoginAccount() { | | } | ...+setter and getters | and I have my "userRegistration" session bean: | @Stateful | @Name("userRegistration") | @Scope(ScopeType.SESSION) | public class RegistratorAction implements Registrator { | | | @Logger | private Log log; | | @In @Out | public LoginAccount account; | | @PersistenceContext(type = EXTENDED) | private EntityManager em; | | | public String register() { | | log.info("persisting #0", account.toString()); | em.persist(account); | return null; | } | but when I click on the link to this page, I get following error: /register.xhtml @19,80 rendered="#{userRegistration.account==null}": Bean: org.javassist.tmp.java.lang.Object_$$_javassist_39, property: account | so I changed all occurences of "userRegistration.account" into "account" thinking it might be in a global context. Now, the site displays and I can enter my name and email. But when I press the submit button, nothing happens. "register()" is not called on the Session, and neither "getRealName()" or "setRealName()" of the entity are called. Could somebody give me a hint what I'm doing wrong? I'm pretty frustrated that I can't even get a helloWorld-type application to work. thanks Dirk View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053633#4053633 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053633

[JBoss Seam] - Re: Session problems

by fernando_jmt

I don't understand you very well, nevertheless I avoided the LazyInitializationException using SMPC and this in my faces-config: | | <lifecycle> | <phase-listener>org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener</phase-listener> | </lifecycle> | | | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053632#4053632 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053632

[JBoss Seam] - Re: How to flush a persistence context when the conversation

by gavin.king＠jboss.com

So what you are saying is: you want to persist stuff in the database, but you don't want to persist stuff in the database? Well, you need to choose :-) Actually, an option is to set your HttpSession and SFSB timeouts much longer than the passivation time, and let the server serialize the intermediate states to disk.

[Installation, Configuration & Deployment] - Re: GC hell ?

by PeterJ

Do you really need a 4GB heap with a 2GB young generation? Bigger is not necessarily better when it comes to Java heaps. It does look like you are freeing up 2GB of garbage every 10 seconds, that is a lot of garbage. Some code must be generating that garbage. It also looks like your working set size is around 160MB. I would try setting Xms/x to 900MB and Max/NewSize to 300MB. Or perhaps 1200M/400M. Of course, at the rate your app is generating garbage that will cause GCs to occur more often.

Maybe check /etc/hosts, run ifconfig, make sure the address you're passing is valid? S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053627#4053627 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053627

[JBossCache] - Re: JBossCache transaction isolation levels

by manik.surtani＠jboss.com

I've added a more comprehensive set of unit tests around isolation levels, but cannot recreate the 2nd failure you talk about above (with READ_UNCOMMITTED). Perhaps the EM has another layer of caching? See http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jboss/JBossCache/tests/functio...

[JBoss Getting Started Documentation] - Re: Bank example compile error.

by PeterJ

Somewhere along the line one of the JSP-related libraries changed. Perhaps it was a change in Tomcat 5.5. It has been a while since I tracked down the problem. A lengthy discussion, and the sourlion, can be found in the post http://www.jboss.com/index.html?module=bb&op=viewtopic&t=93866.
