[JBoss Portal] - Re: JSP changes with live0in support

by thomas.heute＠jboss.com

Those files are not manageable by the CMS. Your files need to be in the CMS "server". If you want to display files that are inside your war file, you need to write a portlet that will include the JSP/HTML. The same way User portlet is made.

[EJB 3.0] - Re: entityManager.find() returns null

by tboswell

anonymous wrote : Some of my coworkers have reported similar behaviour of a sporadic nature...simple calls to EntityManager.find(Class,id) return null when the object is clearly in the DB. They've also stated that using EntityManager.createQuery("SELECT obj FROM ClassName obj WHERE obj.id=?") will sometimes return the object immediately after the finder fails. I tried getting the object by using a createQuery() myself and still found I was returned a null value. The behaviour I have seen with the find() function has not been sporadic but consistently failing, when the PK was a string. entityManager.find(Language.class, "en "); Ah, yes. This rings a bell...I seem to recall an issue with Oracle padding out char columns with spaces. I will change the column to a varchar and retest. Thanks for the thoughts everyone.

[JBoss jBPM] - Re: Multiinstances of the same process

by jits_1998

Post the console log and code for us to see. Try and get only the relevant portion. Also, are all the three instances actually saved in db? Can you do a "select * from jbpm_processinstance". If this does not return anything, you can try closing the jbpmContext after saving the process instance and then open a new one to get the graph session and use this graphsession to search for process instances. cheers!

create a component which holds the constants as properties, and use EL: <h:outputText value="#{constants.someValue}"/> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972859#3972859 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3972859

[JBoss Seam] - Re: When a component is not found should Seam warn or fail?

by gavin.king＠jboss.com

One approach would be to require explicit declaration of all context variables. Many scripting languages have this as an option for global variables. So in components.xml, you could write: | <variables implicit="none"> | <variable name="bar"/> | <variable name="foo" scope="conversation" type="Foo"/> | </variables> | This would eliminate problems of misspellings, and reduce problems of namespace conflicts View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972857#3972857 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3972857

[JBoss Seam] - Re: When a component is not found should Seam warn or fail?

by max.andersen＠jboss.com

Is there anything in EL that allows you to force existence of a variable ? This is similar to the struggles i had with velocity vs freemarker. Velocity assumes non-existence is ok and just output null where as FreeMarker takes the opposite stance and complains if it does not exist plus having syntax for allowing you to provide the default in case of "non-existence". I like the freemarker way much better since you are explicit about wether null/not-there is expected or not. In any case, providing a way for an EL expression to say "this variable should/must be here" + a decent exception message in case it is not, would be a good help to everyone trying to write an application.

[JBoss jBPM] - Re: Multiinstances of the same process

by antitrust1982

First iI modify my code in order to delete the jbpmsession, I use now just the jbpmcontext. For creating an processInstance I try to put just after a creation of process instance " Collection processinstances=graphSession.findProcessInstances(pd.getId());" but I have an error of transient unsave. SO I move my loop which return my process instances before. But I have 3 instances of portlets on my portal so I must have some porcess instances whne I execute it but my collection of process instances id is always empty... how can I resolve it. thank you for you help antitrust1982 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972836#3972836 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3972836
