[Design of JBoss Web] - How to create a web share in jboss

by asilviu

Hi everyone, I need to expose a folder as a web shared folder in jboss so that a user can add that folder, for example, in his "My network places" under windows xp. Is this possible with the out of the box JBoss or do I have to write a custom servlet for that? If I have to write my own servlet to handle this, does anyone have any resources for me to begin with as I am new to java and JBoss and I could not find anything on this subject on google. Thanks a lot, Silviu View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242206#4242206 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4242206

[Design the new POJO MicroContainer] - Re: Parallel deployments

by david.lloyd＠jboss.com

>From a performance perspective, there actually isn't a lot of difference between blocking when the queue is full vs. executing directly - it's the difference between N possible executing threads and N-1 possible executing threads, if you think about it.

[Design the new POJO MicroContainer] - Re: Parallel deployments

by david.lloyd＠jboss.com

A design change I'd like to make to jboss-threads for AS 6 is the ability to separate the thread pool from the executor config, so that two executors can have different rejection policies for the same underlying thread pool. Whether or not it will be possible remains to be seen though.

[Design of JBoss ESB] - Re: Smooks lifecycle resources

by Kevin.Conner＠jboss.com

I have added the smooks explicit lifecycle resource and covered the two memory leaks from earlier. There are still some issues with the codebase, however, but we can address those as part of the 4.7 release. The issues which stand out at the moment are the removal of the SoapUIClientService and the Smooks usage within the wise integration. I'll create issues for those later this afternoon. I also noticed that there are a few areas which are creating Smooks instances and not cleaning up, usually because their API does not fit this. The lifecycle code will catch this but it would be better if we can identify these at some point and clean up the associated APIs.

[Design of JBoss jBPM] - Re: Completion of Tasks results in deletion of Comments ente

by shekharv

Had a few more comments about how history is currently being tracked. I am not aware of what the plan is in terms of providing history related features, for jbpm 4.xx similar to the lines of what was supported by jbpm3, hence my curiosity. Let me try to make my case here: A typical way of using jbpm is to embed/integrate it into the client application. So the domain data of the client application is linked up to the domain of the workflow(process definition, process instance, tasks, etc). The domain entity that is workflow enabled is linked up to process-instance. So this way jBPM is responsible for managing the workflow, keeping track of state, creating tasks, etc etc. Whereas the client domain would contain all the other data that is needed by the client application. So you essentially are linking up two different pieces of data together. An insurance claim table would likely store the process_instance_id as one of it's columns,(and also vice versa, especially with the key based ids in jbpm4). Now every step/task in the workflow, users of the client application might do one or more of the following: 1.) add comments to the task/process_instance. 2.) maybe even store some files. 3.) add some data to the workflow. This is where history and the ability to track it comes into place. If there is any data that we want to store on the process-instance level, we can store it using the process-instance key. Any data that we want to store on the task level, like associating which attachment was added at what step of the workflow, seems to be difficult to do in a straightforward manner currently. The task is being deleted from the task table, and is inserted into the JBPM4_HIST_ACTINST. At this point we lose the 'id' related to the task. So now way to associate the attachment with the task that it was added to. I might be missing an angle here w.r.t doing this in v4. But it would seem that at least for the activity_history, we need to store the id of the activity so as to track items on the individual activity level? This helps us to display a comprehensive history of what all happened, combining the data from the jbpm and client end and display it to the user.

[Design the new POJO MicroContainer] - Re: Parallel deployments

by kabir.khan＠jboss.com

There was some talk on #jboss-dev about using an executor in the controller during bootstrap and then to avoid having too many thread pools configured to replace that with the system thread pool once that is installed. Assuming that the system thread pool in AS trunk is the one deployed in thread-pool-jboss-beans.xml: |  | <deployment xmlns="urn:jboss:bean-deployer:2.0"> | | <threads xmlns="urn:jboss:threads:1.0"> | <thread-group name="SystemThreadFactoryGroup" group-name="System Threads"/> | <thread-factory name="SystemThreadFactory" group="SystemThreadFactoryGroup"/> | |  | <thread-pool-executor name="ThreadPool" thread-factory="SystemThreadFactory" queue-length="1000"> | <core-pool-size count="5" per-cpu="2"/> | <max-pool-size count="10" per-cpu="3"/> | <keepalive-time time="30" unit="seconds"/> | <reject-policy name="block"/> | </thread-pool-executor> | </threads> | </deployment> | I don't think this pool will work for the controller if my understanding of | <reject-policy name="block"/> | is correct (that the caller blocks until a thread is available). The behaviour of the controller is to try to deploy asynchronous contexts via the executor, but if the executor is full to deploy the context in the calling thread. So I need a reject policy that behaves like ThreadPoolExecutor.AbortPolicy or ThreadPoolExecutor.CallerRunsPolicy for the pool handling asynchronous deployments. So we have the choice of reusing the system thread pool but potentially blocking on asynchronous contexts (which I think kind of defeats the purpose), or having a small thread pool dedicated to deploying asynchronous contexts.

Take a look at the web service quickstarts and that will give you an idea of ESB capabilities. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242094#4242094 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4242094
