[Design of Clustering on JBoss] - Jboss Clustering Performance Question

by tdakanalis

Hi and sorry for posting here, I am interested on some performance issues related with jboss clustering. In particular, I want to ask if the synchronization between the nodes in a Jboss cluster occurs in a synchronous or asynchronous way. For example, lets suppose that we have a two node cluster (node1, node2) and a user places a request which is served by the node1. Which of the following options is right: a) The node1 serves the request and then the state of the node2 is updated (asynchronous way), b) the state of the node2 is updated and then the node1 serves the request (synchronous way) . In addition, I want to ask if there are measurements about the average time is needed for the node synchronization in a Jboss cluster (in a typical environment) and the relation of that time with the average time for serving a users request. Thanks in advance !!!

[Design of JBoss jBPM] - Re: Is it possible to avoid hibernate?

by jorgemoralespou_2

Hi, I have found that a "last moment change" with the introduction of NewDeployment interface into the api, has left a lot of references to DeploymentImpl where NewDeployment should have been used instead. Also, I think that it seems that there should be more programming against interfaces, as there is a lot of code where there is no easy way to interchange implementing classes.

[Design of JBoss jBPM] - Re: Task I18N support

by kukeltje

Well, xml has the notion of 'lang' on attributes so that would be my fisrt choice. For descriptions, that is easy and whether this attribute/element really holds the value or just an el that references to an external properties file (the java way) is debatable but not realy important. For tasks it is a different story, since the task name (without the lang attribute) is really used as a value, so not many options there, unless adding additional name elementes with lang added does not pose a problem. One other solution is to teach the Walloons to speak Dutch since with 31% they *are* the minority ;-) (but in the mean time teach Tom how to speak French) The thing is, you do not need to change the core initially: http://planetjbpm.wordpress.com/2009/07/05/73/ View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4244620#4244620 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4244620

[Design of JBoss jBPM] - Task I18N support

by gleenders

I use jBPM 4 just on task level to indicate to different users their next tasks. I don't use a task form, just a brief description of what their task is and a button where they can execute the task the moment it''Âs done. Because I want to use this system in Belgium this can only be done with i18n support. For the moment this is not implemented in jBPM 4. Searching for I way to implement this or a workaround these are my current thoughts/considerations: Tasks translations should be in a sub-node under task in the jpdl.xml file. Since they are part of the process definition (changing a translation will result in a new process definition version). I think we can discuss on this: is the translation really part of the definition? If yes, then the only possibility is to include it in the jPDL as said above. If no, we have to bind it to the task definition key (who seems to be the task name). So in that case it would be possible to foresee a system to implement i18n task support by providing a properties file or an extra database table (both based on the task name as part of the key). The drawback of this system is that it would be possible to change the translations within a jBPM version. One way or another I would like to have a method on 'ÃÂTask'ÃÂ [public String getDescription(String locale)] who just returns the description translation based on the locale.

[Design the new POJO MicroContainer] - Re: Installing a context leads to resolve of other unrelated

by david.lloyd＠jboss.com

Okay, it might be a valid use case for autowiring or something. But you don't need to scan all dependencies every deployment to support it; you just need a map of class to a list of active deployments which is updated every time something is deployed/undeployed.

[Design the new POJO MicroContainer] - Re: Installing a context leads to resolve of other unrelated

by david.lloyd＠jboss.com

Implicit dependency by type is not a valid use case. There can only be one bean of a given name, but any number of beans that are of a certain type. Anyway, is there a single instance of this type-based dependency in JBossAS?
