[JBoss Seam] - Elegant handling of foreign key constraints

by pdhaigh

Hi, Is there an elegant way of handling a delete that fails due to a foreign key constraint? @Transactional | public String remove() | { | try | { | return super.remove(); | } | catch (EntityExistsException ve) | { | log.warn("Caught entity exists exception"); | return "removed"; | } | } Allows me to catch the EntityExistsException, but I cannot directly catch ConstraintViolationException. (which is still logged as an error by AbstractFlushingEventListener). cheers phil View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092536#4092536 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4092536

[JBossWS] - Re: XMLSchema, WSDL and wsconsume tool

by mleite

Hi, Richard! Thanks for your help. I've decided to put my complex/simple types within the WSDL file only for experience. Then i've put my WSDL file in a folder called wsdl and put this folder in the WEB-INF dir, but it doesn't work. JBoss still create the WSDL dinamically without my complex/simple types restrictions. Any ideas? Thanks in advance!

[JBoss Portal] - Re: Questions about database connections between portlets

by ebrennan＠hotmail.com

This might be just one of those "Any comments" as I am still learning this stuff also. A couple things about database connections. 1. JBoss AS and Portal uses Hibernate for there connections and it looks like this technology is making good progress in the development world. Hibernate and other similar technologies (toplink) do the db connections for you. They set these connections into a pool and hand them out to the portlet as needed. Once the request is finished, it is returned to the pool. You should be closing the connection as soon load the data (a few milliseconds). 2. I don't know how customized each users portal will be but you can increase efficiency by caching the data. You should be using enity beans to load the items from the database. It you make the bean global you should able to share it across multiple users. Hope this puts you in the right direction.

[JBossWS] - Client side memory leak?

by m0hmad

Hello, I've got EJBs that operates in proxy mode. They just pass thru requests parameters to JBossWS Client implementation and redirect responses back. All WS artifacts, service and endpoints have been generated with wsconsume tool. Soap endpoints are exposed like: public class SoapServicesFactory { | | static private Content contentSoap; // the SOAP client | | static public synchronized ContentSoap getContentSoap() { | if (null == contentSoap) | contentSoap = new Content(); | return contentSoap.getContentSoap(); | } | } The endpoint released right after first remote method invoked, no storing or caching etc being performed. The problem is, ALL artifacts retrieved from WSs as responses will never released by Garbage Collector and sooner or later there Java heap Space criticall error will be. Utilizing profiler I can see that artifacts retained by instances of several classes: - org.jboss.ws.core.soap.ObjectContent - org.jboss.ws.coreEndpointInvocation - java.lang.Object Changing endpoint exposing to: return (new MobileContent()).getMobileContentSoap(); removes the memory leakage but the service works too slowly cos instantiation of Soap Service is too expensive procedure. Can anybody help me with this issue? Looking forward for any response. Thanks in advance.

[JBoss Seam] - Re: s:decorate changed to use DIV instead of SPAN

by damianharvey

Sorry but it does. Look at the pagesource. >From UIDecorate.java under Seam 1.3: | @Override | public void encodeBegin(FacesContext context) throws IOException | { | super.encodeBegin(context); | | Contexts.getEventContext().set("invalid", hasMessage(this, context)); | Contexts.getEventContext().set("required", hasRequired(this, context)); | | context.getResponseWriter().startElement("span", this); | context.getResponseWriter().writeAttribute("id", getClientId(context), "id"); | And then in DecorateRendererBase (split out from UIDecorate) from Seam 2.0: | | @Override | protected void doEncodeBegin(ResponseWriter writer, FacesContext context, UIComponent component) throws IOException | { | UIDecorate decorate = (UIDecorate) component; | | Contexts.getEventContext().set("invalid", Decoration.hasMessage(decorate, context)); | Contexts.getEventContext().set("required", Decoration.hasRequired(component, context)); | | boolean hasMessage = decorate.hasMessage(); | | writer.startElement("div", decorate); | writer.writeAttribute("id", decorate.getClientId(context), "id"); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092527#4092527 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4092527

[Remoting] - Re: difference between socket, http and servlet invokers

by mazz＠jboss.com

They probably all have the same reliability. I would think socket transport is the fastest, since it need not go through any secondary layer, like a webapp layer (i.e. servlet) or an HTTP parsing layer (like http). The differences are in other areas. For example: Using http allows you to more easily tunnel through firewalls (since typically, you'll tunnel over port 80 using the http transport and your firewall may already allow for that - no need to punch another hole). Using servlet allows you to go through a webapp layer that, say, Tomcat provides so you can piggyback on an already deployed Tomcat server - which in turn allows the sslservlet transport to reuse the Tomcat security features i.e. you can reuse the SSL connector and Tomcat's SSL certificate setup.

So if twiddle gets the requestProcessingTime, how do I get it from the Java code snippet that I posted? If my Java code is incorrect, could you suggest a piece of code that could retrieve this?
