[JBoss Seam] - Re: Seam and (or vs) Tapestry 5

by michael.yuan＠jboss.com

So, mgrouch, are you volunteering to help us out with Tapestry integration? :) It should not be too hard since as Norman indicated, the Seam core has no dependency on JSF ... Do you want to give it a try? We'd appreciate it. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072740#4072740 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4072740

[JBoss Seam] - How to build action parameter expression for s:button with v

by lpmon

I need to build a button to pass an argument to an action method. I can hard code the parameter and all is fine. I just cannot figure how to dynamically build it with tags. Key point: I need to use el to specify the Seam "named" method and I also need to use el to specify its argument. This creates a nesting scenario that I cannot figure out. The track var is the object <ice:dataTable id="trackList" var="track" value="#{trackList.resultList}" columnClasses="allCols" rendered="#{not empty trackList.resultList}"> ... ... <ice:column> <f:facet name="header">Click to Play</f:facet> <s:button value="Play" id="play" action="#{connectedUser.playMediaId(track.id)}"/> </ice:column> Track.id is passed as a null string to the method. I created a different method that takes a track object and tried passing track. I get a null object passed to the method. I am adapting the standard SeamGen pages for my app. I can get it to work if I use the select in the seamgen'd trackList page which passes the selected track to the track page. Then on that page I use trackHome.instance as the parameter to the method that accepts a track object. This works. One key difference between the two pages is in the tracklist page (non-working one) the data is provided by the var from ice:dataTable I want to get this to work in the trackList page inside the dataTable View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072738#4072738 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4072738

[JBoss Seam] - Re: seam s:link fetchs list multiple times. big error !

by bulloncito

Done, it was painful, updated to Seam2, and error is identical ; ) Entity Query is fetched multiple times for the very same case, if I use even empty <s:link /> tags, List is fetched multiple times, for entityQuery objects that check for dirtied parameters, this could no be so noticeable as an undesired performance problem, but I insist: This SHOULD NOT be default behavior. And it does happen.

[JBoss Seam] - Re: Seam and (or vs) Tapestry 5

by mgrouch

We always use server side state saving but still observe slow performance with JSF. I'm pretty sure it is attributed to JSF (and not Seam). JSF needs to operate on a tree of components (do various searches on it) and there are 6 phases when it could do that. There seems to be some HTML reformatting happening on server side as well (by ajax4jsf). All of it makes it (in my experience) 5 times slower than same tasks with JSP. (yes it is that bad). All of it makes people to look for new alternatives. Tapestry 5 (which is new, annotation based) looks interesting as well as using Seam with no JSF. In JSF world pages are NOT COMPILED against beans so many errors can't be discovered at build time.

[Remoting] - Re: Multiplex socket exmaple with SSL?

by ron.sigal＠jboss.com

I just noticed that you mentioned SSl in the thread title. There is a version of multiplex called sslmultiplex. I don't see any sslmultiplex sample code, but there is a lot of unit test code in org.jboss.test.remoting.transport.multiplex.ssl and subpackages. Again, consider sslbisocket.

[JBoss jBPM] - Re: Memory usage in Workflow wait states

by jeffcwang

Hello Ronald, Can you please elaborate on why you'd have to restart the j2ee server each day if JBPM handles > than 100 process instances/day? Does JBPM have a problem scaling? It seems like 100 process instances isn't that many... thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072734#4072734 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4072734

[Remoting] - Re: Multiplex socket exmaple with SSL?

by ron.sigal＠jboss.com

In the directory org.jboss.remoting.samples.multiplex are examples of virtual socket use. In the directory org.jboss.remoting.samples.multiplex.invoker are examples of use of the multiplex transport. That said, I'm encouraging people to consider the bisocket transport in place of multiplex. They were both designed to support clients behind firewalls, but bisocket is faster and probably more reliable. It is used by JBossMessaging, which means it gets a lot of production use. I'm not aware of any comparable use of the multiplex transport.

[Remoting] - Re: bisocket usage as a tunneling connection

by ron.sigal＠jboss.com

The answer is "yes". anonymous wrote : so i want the client machine to connect to my server and the connection to be kept open (tunneling) with keep alive pulses. With the bisocket transport you don't need to worry about a keep-alive problem. You can configure the socket timeout value to be zero, so the sockets will stay open indefinitely. In fact, you don't even need to rely on setting the timeout value to zero. The client will create new sockets as needed. anonymous wrote : from now on (once connected) i want the server to be able to call the client in a request - response manner, as if the client is a 'server'. Remoting has a callback mechanism which allows the server to send invocations to the client in an asynchronous manner. See Section "5.6. Callbacks" in the Remoting Guide (http://labs.jboss.com/jbossremoting/docs/guide/index.html). anonymous wrote : i also want the connection/connections to support a pool of connections, so i can have multiple concurrent requests. The socket transport, from which bisocket is derived, maintains a connection pool on the client side and a worker thread pool on the server side. The same is true, in reverse, with respect to callbacks going from the server to the client. anonymous wrote : i also want the connection to use https or ssl on tcp/ip. There is an sslbisocket version of bisocket. anonymous wrote : is bisocket the tool for me? Yes, I believe it could be. anonymous wrote : if it is - how? Ah, well, I'd say take a look at the Remoting Guide and the sample code in the distribution.
