[JBoss Cache: Core Edition] - Re: on child insert parent, child collection updated in DB b

by bstansberry＠jboss.com

Sure, the pasted code should be fine, thanks. I'd adapt this into the hibernate-jbc integration test suite, which has its own tx mgmt utilities, so the Spring thing shouldn't be a big deal.

[JBoss Cache: Core Edition] - CacheJmxWrapperMBean is deprecated, but the documentation st

by jshowalter

We have this code based on what's in the documentation, in order to get our cache (deployed using the jmx microcontainer) and return it to our application code: final MBeanServer server = MBeanServerLocator.locateJBoss(); final ObjectName objectName = new ObjectName(sCacheName); @SuppressWarnings("unchecked") final CacheJmxWrapperMBean<String, Object> cacheWrapper = (CacheJmxWrapperMBean<String, Object>) MBeanServerInvocationHandler.newProxyInstance( server, objectName, CacheJmxWrapperMBean.class, true); sCache = cacheWrapper.getCache(); return sCache; But CacheJmxWrapperMBean is deprecated. What's the correct way to get the cache now?

[JBoss Tools (users)] - Re: Re-deploying

by max.andersen＠jboss.com

so something changed that file without refresh. Try refresh the files and run again... ...hmm..on second thought that bug is an old one in eclipse 3.4.0 or wtp (not sure) ...are you sure you are on the latest version ?

[JBossMQ] - Connecting a remote queue (oc4j server) in JBoss

by romain3396

Dear all, I've created a queue in oc4j, I can post and read messages and receive it via a Java Client. Now I want to create a MDB in Jboss to consume these messages. I've followed this Jboss tutorial http://www.jboss.org/community/docs/DOC-9893/version/5 All is deployed, but the messages are not consumed : no logs, no exceptions... I don't understand 1 thing : in these examples, I've not documented the JNDI of the oc4j queue, how can I set it ? (queue/myqueue) In the jms.ds-xml of Jboss, I've created <mbean code="org.jboss.jms.jndi.JMSProviderLoader" | name="jboss.mq:service=JMSProviderLoader,name=RemoteJBossMQProvider"> | <attribute name="ProviderName">RosyStatJMSProvider</attribute> | <attribute name="ProviderAdapterClass"> | org.jboss.jms.jndi.JNDIProviderAdapter | </attribute> | <attribute name="FactoryRef">XAConnectionFactory</attribute> | <attribute name="QueueFactoryRef">XAConnectionFactory</attribute> | <attribute name="TopicFactoryRef">XAConnectionFactory</attribute> | <attribute name="Properties"> | java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory | java.naming.provider.url=ormi://myoc4jserver:12502/ | java.naming.security.principal=login | java.naming.security.credentials=password | </attribute> | </mbean> | And this is the Jboss.xml of my MDB <?xml version="1.0" encoding="UTF-8"?> | <jboss> | <enterprise-beans> | <message-driven> | <ejb-name>MyMDB</ejb-name> | <destination-jndi-name>queue/MDBReceiveQueue</destination-jndi-name> | <invoker-bindings> | <invoker> | <invoker-proxy-binding-name>whatever-message-driven-bean</invoker-proxy-binding-name> | </invoker> | </invoker-bindings> | </message-driven> | </enterprise-beans> | | <invoker-proxy-bindings> | <name>whatever-message-driven-bean</name> | <proxy-factory-config> | <JMSProviderAdapterJNDI>java://RosyStatJMSProvider</JMSProviderAdapterJNDI> | <ServerSessionPoolFactoryJNDI>StdJMSPool</ServerSessionPoolFactoryJNDI> | <MaximumSize>15</MaximumSize> | <MaxMessages>1</MaxMessages> | <MDBConfig> | <ReconnectIntervalSec>10</ReconnectIntervalSec> | <DLQConfig> | <DestinationQueue>queue/DLQ</DestinationQueue> | <MaxTimesRedelivered>10</MaxTimesRedelivered> | <TimeToLive>0</TimeToLive> | </DLQConfig> | </MDBConfig> | </proxy-factory-config> | | </invoker-proxy-bindings> | </jboss> Here is my client which connects to the oc4j server (and works) Properties properties = new Properties(); | try { | properties.load(new FileInputStream(config)); | } catch (Exception e) { | throw new RuntimeException("Error while reading property file.", e); | } | Context ctx; | | try { | Properties parm = new Properties(); | | parm.setProperty("java.naming.factory.initial", | "com.evermind.server.rmi.RMIInitialContextFactory"); | parm.setProperty("java.naming.provider.url", "ormi://myoc4jserver:12502"); | parm.setProperty("java.naming.security.principal", "login"); | parm.setProperty("java.naming.security.credentials", "password"); | | ctx = new InitialContext(parm); | | QueueConnectionFactory connectionFactory = (QueueConnectionFactory) ctx | .lookup("jms/QueueConnectionFactory"); | | connection = connectionFactory.createQueueConnection(); | connection.start(); | session = connection.createQueueSession(false, | Session.AUTO_ACKNOWLEDGE); | queue = (Queue) ctx.lookup(properties.getProperty("queue/myqueue")); View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4215481#4215481 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4215481

[JBoss Cache: Core Edition] - Re: on child insert parent, child collection updated in DB b

by dukehoops

Brian, I pasted my test code in a post right before yours. Is that insufficient? Unfortunately, that test code does rely on some of our own TX management code (which extends Spring's) so it seems you'd have to modify this code, replacing our tx template objects with your own. Will that work for you?

[JBoss Portal] - Re: trim whitespace at jsp

by apemberton

JBoss Portal 2.7 uses JBoss AS 4.2.3, which in turn uses Tomcat 5.5 under the covers as the servlet engine. Tomcat 5.5 is Servlet 2.4/JSP 2.0 compatible, so you can't use the JSP 2.1 trimDirectiveWhiteSpaces feature. You can, however, use the trimSpaces init-param per http://raibledesigns.com/rd/entry/trim_spaces_in_your_jsp One warning: you may run into issues where white space is trimmed a bit further than you may be expecting. For example, two <c:out /> tags in a row may not have a space between them. As for bang for your buck, I'd recommend looking into GZipping your portal page requests - which may save more bandwidth than trimspaces in your environment. I plan on writing a blog article in the next weeks discussing some of these Portal-tier performance tuning tips. Good luck!

[JBoss Portal] - Programmatically Create Portal Pages

by analyzediz

Hi all -- I was wondering if anyone know of a good approach to programmatically create a portal page from a preexisting template page. Essentially, I have a requirement to be able to clone a template page with portlets in a specific layout etc. The user will be able to, at the click of a button on a management portlet, create a clone of the template portal page. The clone will contain a copy of each portlet that exist on the template page as well. Does anyone out there know of a systematic way of doing this? I presume as a last resort I might have to go to the database layer to make copies of each of the database records that represent each of the portal objects (template page, template portlets etc.) and link them together. Any pointers will be greatly appreciated. Thanks!

My address is to the left. anonymous wrote : | I guess the problem lies either with versioning (either Hibernate versioning or MVCC versioning) or (insufficient?) locking. I've think you've exposed a logical flaw with the locking -- either in the hibernate-jbc integration or with the basic design in hibernate core itself. With an entity this kind of thing would not be a problem because a database lock on the record would either 1) block b2 updating the entity until a's tx is done 2) block a1's read until b's tx is done. But with a collection there is no single database record that both tx's need to lock on. anonymous wrote : | You said previously that assumptions around synchronization ordering were fixed for JBossTS and JBC specifically. Was the fix to order synchronizations in TX manager impl? Yes. anonymous wrote : | The reason I ask is that Spring seems to use a Synchronization to close Hibernate Sessions. Is there an expectation that *that* syncrhonization fire *before* JBC's synchronization? If you could give me a link to the Spring code, that would be good. This doesn't sound like a problem though; the key thing is that the session is flushed to the database before JBC's Synchronization's beforeCompletion() is called. Hibernate's own CacheSynchroniztion handles that. Sounds like Spring is calling Session.close() which is a housekeeping operation that would come *after* the above.

[Security & JAAS/JBoss] - Re: Minimal JBoss config to use GSSAPI/Kerberos acceptSecCon

by chriscorbell

Well now for the fun part - getting it to work on Windows. (Our app gets deployed there as well). The same configuration does not yet work for me when JBoss is running on Windows. The LoginContext login() seems to succeed, but the familiar fault [GSSException: No valid credentials provided] returns when trying to create the GSSCredentials. I've tried a few different approaches to specifying the path to the keyTab thinking that might be the culprit, with no better success. One symptom is that the output for debug=true in the login policy does not appear to be honored on Windows, which makes me suspect that the login-config.xml is somehow being handled differently. (It should output a lot of verbose information including the login policy module-options).
