[Design of JBoss Portal] - Re: Java 5 migration strategy

by chris.laprun＠jboss.com

Also, what's the target for that migration? Subversion trunk I assume? Wouldn't it make it difficult to fix issues both on trunk and 2.6 branch?

[Design of JBoss Portal] - Re: Java 5 migration strategy

by chris.laprun＠jboss.com

Do we need to migrate (i.e. do we need to convert existing code) or can we just start using it for new code?

[Design of AOP on JBoss (Aspects/JBoss)] - Re: AOP ClassLoader/Scoping needs thoroughly revising

by adrian＠jboss.org

Before I continue with the use cases, two caveats. 1) I going to be loose with what I explain, and try to explain it from a user's point of view. e.g. If talk about intercepting database calls on Oracle, the user is unlikely to know that Oracle is the implementing class and instead specify join points on the jdbc interfaces. In the following I'll probably say both but it is really the same thing, hopefully you can follow this loose speak without pulling me up on what is done technically. 2) Some of what I describe as not possible can be done, but it is either not easy or not obvious how to do it. e.g. In some scoping situations you can make it work by using the MC's aop-mc-int and use proxies to get "instance level adivce stacks" but I'm not assuming that is what will be or we want to be used in all cases?

[Design of JBossCache] - Re: @CacheListener impl must be public?

by bstansberry＠jboss.com

I already changed the exception message bit. Do you want me to post a JIRA for that? I wrote a little test program and it had no trouble doing inspection on a private class and then invoking a public method on it: | package org.jboss.cache.notifications; | | import org.jboss.cache.notifications.annotation.CacheListener; | import org.jboss.cache.notifications.annotation.NodeModified; | import org.jboss.cache.notifications.event.NodeModifiedEvent; | | public class Testee | { | public Object getCacheListener() | { | return new InnerClass(); | } | | @CacheListener | private class InnerClass | { | @NodeModified | public void nodeModified(NodeModifiedEvent event) | { | System.out.println("Node modified " + event); | } | | public long getLong() | { | return 0L; | } | } | } | | package org.jboss.cache.notifications; | | import java.lang.reflect.Method; | | import org.jboss.cache.notifications.annotation.CacheListener; | import org.jboss.cache.notifications.annotation.NodeModified; | import org.jboss.cache.notifications.event.EventImpl; | | public class Tester | { | | public static void main(String[] args) | { | Testee testee = new Testee(); | Object listener = testee.getCacheListener(); | | if (!listener.getClass().isAnnotationPresent(CacheListener.class)) | throw new IncorrectCacheListenerException("An Object must have the org.jboss.cache.notifications.annotation.CacheListener annotation to be considered a cache listener, and must be publicly accessible!"); | // now try all methods on the listener for anything that we like. Note that only PUBLIC methods are scanned. | for (Method m : listener.getClass().getMethods()) | { | if (m.isAnnotationPresent(NodeModified.class)) | { | System.out.println("Annotation found"); | try | { | m.invoke(listener, new Object[] { new EventImpl() }); | } | catch (Exception e) | { | e.printStackTrace(System.out); | } | System.out.println("Method invoked"); | return; | } | } | System.out.println("Annotation not found"); | } | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060822#4060822 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4060822

[Design of JBoss jBPM] - get a token in another task

by galvino

Hi everybody . I have a problem to go to next task-node with jbpm in a web application by using struts. i did a small process like this: anonymous wrote : start | task1 | task2 | end On my first bean in strut, i deploy process and i go to the first task. But when i write this in order to go to the next task: anonymous wrote : | TaskMgmtSession taskMgmtSession = jbpmContext.getTaskMgmtSession(); | | TaskInstance taskInstance = taskMgmtSession.loadTaskInstance(1); | taskInstance.setActorId(jbpmContext.getActorId()); | taskInstance.start(); | | Token token = graphSession.loadToken(1); | Transition transition=null; | String transitionName=null; | | if (token.getNode().getLeavingTransitions().isEmpty() == false) { | Iterator availableTransitionsIterator = token.getNode().getLeavingTransitions().iterator(); | while (availableTransitionsIterator.hasNext()) { | transition = (Transition) availableTransitionsIterator.next(); | } | transitionName=transition.getName(); | } | | token.signal(transitionName); | ProcessInstance processInstance = token.getProcessInstance(); | | jbpmContext.save(processInstance); | there are an error : anonymous wrote : | Integrity constraint violation - no parent FK_TASKINST_TASK table: JBPM_TASK in statement [insert into JBPM_TASKINSTANCE (NAME_, DESCRIPTION_, ACTORID_, CREATE_, START_, END_, DUEDATE_, PRIORITY_, ISCANCELLED_, ISSUSPENDED_, ISOPEN_, ISSIGNALLING_, ISBLOCKING_, TASK_, TOKEN_, SWIMLANINSTANCE_, TASKMGMTINSTANCE_, CLASS_, ID_) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'T', null)] | what's this error means ? i think it can't execute *.signal() why ?

[Design of JBoss Transaction Services] - Metadata Support for Transactional Web Services

by maciej.machulak

Hi, I have been working on support for transactional Web Services (with accordance to the Business Activity model described in the WS-BusinessActivity specification) for some time and I am close to releasing the first version of my framework. The framework is built on top of the XML Transaction Service (XTS) component of the JBoss Transaction Service. I will be setting up a Web site with the source code, documentation and some examples but first I would like to give you an overview of what and why has been done. At this moment writing transaction-aware Web Services is relatively problematic and requires a lot of support from business programmers. Developers need to manually wire up original services with their compensation actions and must ensure the correctness of those links (e.g. in terms of data that needs to be shared). Moreover, it is necessary to follow transaction-related patterns where a developer must code not only the business logic but a participant as well. The latter one is an entity, which is capable of responding to transaction protocol messages (such as commit or compensate messages). Typically, a third component is also developed ? this component usually links participants with the business logic and is often referred to as the manager. My aim was to facilitate development of transaction-aware Web Services and provide a comprehensive framework which would release programmers from mixing transaction-related code with business logic of their applications. The framework has a very clean API, which can be easily learnt and used. I will briefly describe it and show an example of how it can be used to expose an EJB component as a transaction-aware Web Service. Programmer?s API The API has been designed following the conventions proposed by the JSR-181 specification for exposing EJB components as Web Services. It consists of the following annotations: @BAService ? specifies the service in terms of its state management; @BAAgreementType ? specifies the agreement protocol the service wants to participate in; @BACompensatedBy ? specifies the compensation action and a type of compensation; @BAParam ? annotates the service?s parameter so that it can be processed by the compensation mechanism; @BAResult ? annotates the service?s return value to be processed by the compensation mechanism; @BACompensationManagement ? annotates a BA compensation manager object to enable transparent dependency injection. Moreover, the programmer may use put(id,Object) and get(id) methods, which are invoked on the previously mentioned compensation manager to store and retrieve any additional data, which might be used for compensation. Example To understand how those annotations and methods can be used I will present an example of an EJB component (stateless session bean), which is exposed as a transaction-aware Web Service. To expose a method as a transaction-aware Web Service, the business programmer must mark it with previously mentioned annotations as shown in the example below. If no additional data must be stored, then annotations are enough. The framework will transparently apply all necessary transaction mechanisms. If more flexibility needs to be achieved, the programmer may use additional methods (put() and get()) to store and retrieve any data that could be potentially used during compensation. The compensation action must only have its parameters annotated so that middleware mechanisms can match them with any data remembered during the execution of the original service (additional support for numerical identifiers is currently being developed so that the compensation action will not need to have any annotations). As shown in the example, the compensation action does not need to be transaction-aware. Moreover, it does not need to be exposed as a Web Service at all. | @Stateless | @Remote(HotelBA.class) | @WebService(name="HotelBA") | @SOAPBinding(style = SOAPBinding.Style.RPC) | @HandlerChain(file = "jaxws-ba-handler-server.xml") | public class HotelBAImpl implements HotelBA | { | @BACompensationManagement | private CompensationManager cm; | | @WebMethod | @BAService(BAServiceType.MODIFY) | @BAAgreement(BAAgreementType.PARTICIPANT_COMPLETION) | @BACompensatedBy(value="cancel",type = BACompensationType.CUSTOM) | @BAResult("resNo") | public Integer book(@BAParam("user")String user, @BAParam("pass")String pass, Integer room) | { | // ... business logic | cm.put("charge",5); | // ... business logic | return reservationNumber; | } | | @WebMethod | public void cancel(@BAParam("user")String user, @BAParam("pass")String pass, @BAParam("resNo")Integer rNumber) | { | // ... business logic | Integer refund = (Integer) cm.get("refund"); | if (refund != null) | { | // ... business logic | } | // ... business logic | } | } | Future releases of the framework will provide support for remote compensation and will allow specifying transaction-related requirements in XML files (to allow exposing existing components). I hope that the overview and example provided enough information to give a flavour of what the framework is aiming to achieve. Information about the first release and a link to the website will be posted here as soon as everything is ready.
