Hi, I am getting the following exceptions when running the seamdiscs example on JBoss AS 4.2.0 GA. What I did are: 1. Download and install JBoss AS 4.2.0 GA; 2. Check out the jboss-seam module from CVS; 3. Run ant under the project folder; 4. Run ant under jboss-seam\trinidad; 5. Modify build.properties under jboss-seam\trinidad\example\seamdiscs to point to the correct location of JBoss AS 4.2; 6. Run ant under jboss-seam\trinidad\example\seamdiscs; Thanks, Tong javax.servlet.ServletException: java.lang.IllegalArgumentException: Stack must not be null | org.jboss.seam.web.ExceptionFilter.endWebRequestAfterException(ExceptionFilter.java:97) | org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:66) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:81) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:47) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:127) | org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:277) | org.jboss.seam.web.AbstractAjax4jsfFilter.doFilter(AbstractAjax4jsfFilter.java:35) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.SeamFilter.doFilter(SeamFilter.java:127) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | | root cause | | java.lang.IllegalArgumentException: Stack must not be null | org.jboss.seam.core.ConversationEntry.<init>(ConversationEntry.java:40) | org.jboss.seam.core.ConversationEntries.createConversationEntry(ConversationEntries.java:52) | org.jboss.seam.core.Manager.createConversationEntry(Manager.java:685) | org.jboss.seam.core.Manager.beforeRedirect(Manager.java:834) | org.jboss.seam.core.Manager.beforeRedirect(Manager.java:852) | org.jboss.seam.exceptions.DebugPageHandler.handle(DebugPageHandler.java:24) | org.jboss.seam.core.Exceptions.handle(Exceptions.java:78) | org.jboss.seam.web.ExceptionFilter.endWebRequestAfterException(ExceptionFilter.java:85) | org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:66) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:81) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:47) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:127) | org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:277) | org.jboss.seam.web.AbstractAjax4jsfFilter.doFilter(AbstractAjax4jsfFilter.java:35) | org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:56) | org.jboss.seam.web.SeamFilter.doFilter(SeamFilter.java:127) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053205#4053205 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053205

[JBoss jBPM] - Updating processdefinition.xml

by warmonga

Hi all, I am trying to update an existing processdefinition.xml by adding a decision-node to it. Accesing it and adding the node works fine but I do not find a way how to transform the process definition from the java object model back to the XML representation. Unfortunately there is no method like processDefinition.saveAsXml(String location) or similar. My current code looks like this: | ProcessDefinition processDefinition = ProcessDefinition.parseXmlInputStream(new FileInputStream("src/main/jpdl/DecisionProcess/processdefinition.xml")); | | Node creationNode = proDefinition.getNode("Creation"); | Node appNode = proDefinition.getNode("Approvement"); | | Decision decisionNode = new Decision("check"); | | | Transition toCheck = creationNode.getDefaultLeavingTransition(); | Transition toNext = new Transition(); | | toCheck.setTo(decisionNode); | toNext.setTo(appNode); | decisionNode.addLeavingTransition(toNext); | decisionNode.addArrivingTransition(toCheck); | appNode.addArrivingTransition(toNext); | processDefinition.addNode(decisionNode); | Does anyone have an idea how to save the process definition to processdefinition.xml again? And, if so, maybe you also have a clue how to then make the belonging process picture (processimage.jpg) being updated so that the newly inserted decision node will be visible on it? Many Thanks in advance!

[JBoss AOP] - Re: annotation

by system.out

I also tried this: <typedef name="MySessionBeans" expr="class($instanceof{javax.ejb.SessionBean}) AND class(org.jboss.injbossaop.ejb.*)" /> | <bind pointcut="execution(* $typedef{MySessionBeans}->@Oneway(..))"> | <interceptor class="org.jboss.injbossaop.lib.SimpleInterceptor"/> | </bind> With no success. I have getValue() method in org.jboss.injbossaop.ejb package annotated with @Oneway. Please note that if I replace @Oneway with getValue, it will work!! Maybe this syntax is not valid, however, I don't get any exceptions in AS. What I am looking for is abstracting method names with annotations.

[JBoss Portal] - Problems with accessing to Management portlet

by tex321

Problem: I am starting with JBoss portal usage and have one basic question about Management portal appearance. I started to read User Guide for JBoss portsl 2.6 CR2 and in Chapter 2.2.1 "Managing portal instances", there is description of Management Portlet. On screen shot there is treeview on the left and details page on the right (Manage: portal, instances, portlets) all within Management Portlet. But when I run JBoss portal (started with $JBOSS_HOME/bin/run.sh) and try to access the same page: I first login as admin/admin, then click on Admin link and then click on Home tab. Appearance of Management portal is completely different. On the left I don't have treeview but have portlet Pages, on the right I have Management Portlet with three tabs (Portal Objects, Portlet Instances, Portlet Definitions). Am I accessing the same Management portlet or not? So I guess there are two possible reasis for this. First is that I am not accessing correct Management Portlet and the other is that if documentation is outdated or maybe I have some problems with installation of JBoss portal. I had same problem with quick start guide. Thanks for your help. I know that this is really basic question but I must be sure that I am on the right path. Environment: JBoss Portal Version: JBoss Portal 2.6 CR2 Ninja (downloaded from JBoss in bundle Jboss AS + portal) JBoss AS Version: 4.0.5 GA Database Vendor and Version: default JDBC Connector and Version: default OS Platform: (server = Fedora Core 7; client = Windows XP) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053201#4053201 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053201

[JBoss AOP] - annotation

by system.out

I am trying to tag the intercepted methods individually using annotation as described in userguide 4.1. Methods and annotations. I created a sample code and it is working fine (similar to Method Interception Sample). However when I tried to apply similar approach to intercept the session bean, interception didn't happen: Here is the jboss-aop.xml: <aop> | <aspect class="OnewayAspect" /> | <bind pointcut="execution(void *->@Oneway(..))"> | <advice name="oneway" aspect="OnewayAspect" /> | </bind> | </aop> all methods in session bean have Oneway annotation !! After that I modified the jboss-aop.xml with the following: <typedef name="MySessionBeans" expr="class($instanceof{javax.ejb.SessionBean}) AND class(org.jboss.injbossaop.ejb.*)" /> | <bind pointcut="execution(* $typedef{MySessionBeans}->getValue(..))"> | <interceptor class="org.jboss.injbossaop.lib.SimpleInterceptor"/> | </bind> It was intercepted! Can anybody tell me what is wrong?

[JBossWS] - soap:address location using HOSTNAME rather than IP address

by sagneta

Currently I am using JBoss 4.0.4 and using @WebMethod on EJB 2.0 Session Beans to provide SOAP access to various public methods. Everything works fine except that the soap:address location URL contains the actual hostname rather than the IP address. I unfortunately require the IP address as many customers lack decent DNS support, sometimes for security reason. In any event, JBoss produces WSDL with the following snippet at the end: - <soap:address location="http://sagneta-bos:8080/ws/TestLogin" /> Notice the sagneta-bos hostname? I need that to be an IP address. I cannot determine from the documentation how to make the JBoss server produce a WSDL XML document that produces an address location URL that uses the IP address rather than the HOST name. It appears that jboss.bind.address is always used. Any help would be appreciated. Thank you, Stephen View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053199#4053199 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4053199

[JBoss Seam] - Prevent Multiple Clicks in PageFlow

by djeverson

We have implemented a pageflow that walks a user through a "wizard" to accomplish a task. We have discovered that the users sometimes double click on the "next >" button. On some of the steps in the wizard, the database is getting duplicate data inserted. We have implemented some short-term/stop-gap measures to prevent the duplicate data in the service layer of our app. However, we were curious if there is a best practice that others have used to solve this problem? We are particularly interested if anyone has addressed this issue on a credit card payment screen. We would like to remove the button after the user clicks on it and replace it with a progress bar. Is ajax4jsf suited for this task? If so, does anyone have any examples? Thanks!

[JBoss Portal] - JBoss Portal 2.6 and EJB 3.0

by thepriz

Does JBoss Portal 2.6 work with JBoss AS 4.0.5 using EJB 3.0? I have downloaded the JEMS installer and use the version of portal there but was just wondering if the latest release comming out can be easily deployed in that setup out of the box. If not, what would it take to get it to run in this setup?

[JBoss Seam] - Re: Session context variable missing

by petemuir

@DataModelSelection | @In(required = false, create = false) | @Out(required = false) | private Category currentCategory; Having both @DataModelSelection and @In on the same variable isn't advisable - how does Seam know which one to jnject from? Also, you would probably have more luck if you actually outjected to the SESSION scope, rather than the CONVERSATION scope (by default you it outjects to the scope of it's parent). And, a hint about posting - exclude irrelevant information - I don't need to see your imports, your named queries, all your getters and setters - you've provided so much information to trawl through!
