[JBoss Seam] - Parameter passing for page action

by milli

Hi, How do I pass parameters in the following scenerio?(instead of using session scope) @Name("home") | Class Home | { | private Category category; | | public getCategory() | { | if (null == category) | category = CategoryHome.find(id); | return category; | } | } home.xhtml: ..... <h:commandLink action="#{categoryAction.action(home.category)}" value="Action" /> @Name(categoryAction) | Class CategoryAction | { | private Category category; | | public Category getCategory() | { | return category; | } | | public String action(Category category) | { | this.category = category | return "category.xhtml" | } | }category.xhtml: displays #{categoryAction.category.name} and #{categoryAction.category.description} If I do as above, the category is always null in category.xhtml. If I set the categoryAction scope to Session it works. I'm trying to find out if there is a better way to do this without using session scope. If I'm doing something wrong could you please let me know the right way of doing it. Basically I want to be able to pass objects from home page(home component) to category page(categoryAction component) avoiding another DB query. Any help would be appreciated. Thanks.

[Performance Tuning] - Jndi lookup performance

by int2

Hi everyone, I have done a simple test on jndi lookup (on a separated client). I just really upset that the average time for the lookup is around 400 ms (local machine) and 500ms (remote machine). I just wonder is there something wrong with my performance optimization ? Following is the code of the client public static void main(String[] args) { | // TODO Auto-generated method stub | | if (System.getSecurityManager() == null) | System.setSecurityManager(new RMISecurityManager()); | Calendar c = Calendar.getInstance(); | | Properties env = new Properties(); | env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); | //switch to 'localhost:1100' for performance comparison | env.setProperty("java.naming.provider.url", "192.168.1.2:1099"); | env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming"); | try{ | long start = System.currentTimeMillis(); | Context ctx = new InitialContext(env); | Object ref = ctx.lookup("BBean/remote"); | | | long end = System.currentTimeMillis(); | long el = end - start; | System.out.println("elapse(ms): " + el); | } | catch(NamingException e){ | e.printStackTrace(); | } | } Thank you a lot and regards Boehm View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044599#4044599 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4044599

[JBoss and NetBeans] - debugger not working using JBOSS 4.0.5 GA and NETBEANS 5.5.1

by reyjexter

when choosing Sun Java Application Server 9.0, the debugger seems to be working. This are the step by step process that I do: 1. I update my jsp file 2. build the project, 3. click the "apply code change" button 4. refresh my browser the changes i made can be seen on my browser. but when i'm using JBoss Application Server, everytime i do the same step, the changes i made is not shown. i needed to re-run the debugger in order for the changes to be applied. hope somebody clears this problem thanks in advance rey View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044594#4044594 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4044594

[EJB 3.0] - Re: EJB3 and jndi error.

by oskar.carlstedt

Hi! Take a look in the jmx console/jndi view to see under what name you ejb is bound. For me it looks like you forgot a slash right after the "java:". With kind regards Oskar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044591#4044591 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4044591

[Persistence, JBoss/CMP, Hibernate, Database] - merge detached entity will insert a new entity

by javatwo

em.merge(course); // course is a detached entity I got the following exception: org.hibernate.exception.ConstraintViolationException: could not insert: package.Course. The exception means it tried to insert a new row for merge. The detached entity was initially retrieved from database using course = em.find(Course.class, 876L); // the course id is 876. It has a valid id. (using debugger). If I load the entity from database first, then merge it, it works. em.find(Course.class, 876L); em.merge(course); I have been working on solving this for days. Any helps are appreciated.

[Installation, Configuration & Deployment] - Re: Error running Jboss Session Bean Example

by genman

msg=com/genuitec/trader/ejb/TraderSession (Unsupported major.minor version 49.0) This is the key error. This is seen when you use an older JDK to run a newer class file, e.g. run 1.5 classes on a 1.4 JDK.

[Beginners Corner] - Re: jboss mailing service

by genman

JEE mail support is for sending mail and receiving POP mail, not for mail storage. There was a JBoss Mail Server product, now developed by an external company. Look for the Collab server forum for a link.

[Performance Tuning] - Memory not released after shutting down JBOSS, memory leak?

by javatwo

After rebooting FC 6, then start JBOSS. The total memory usage is about 600M. After accessing the web application deployed on the JBOSS for about 3 hours, the message usage is about 3.5G. Then shutdown the JBOSS. But the memory used is still shown as 3.5G using TOP command. Is this a memory leak? Java JVM 1.6 FC 6 JBoss 4.0.5GA Thanks for help. dave View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044586#4044586 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4044586

[Remoting] - Re: https with path and ejb3 can not be configured

by rino_salvade

I solved the problem with the redirect in the meantime. According to the RFC a redirect 302 should be answered with the same response as the original request, i.e. a POST with a POST. For historical reasons the standard JDK implementation of the JDK answers a POST with a GET. There is a system property that handles this. Set anonymous wrote : -Dhttp.strictPostRedirect=true and a POST will be answered with a POST. That did it :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044584#4044584 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4044584
