[Design of JBoss ESB] - Re: Design of a Content Based Routing Service

by ddunkin

I think this could be accomplished through DSL and helper classes. Here's some untested code to show the direction: Here's what the new rules might look like: | #created on: Oct 30, 2006 | package com.jboss.soa.esb.routing.cbr | | #list any import classes here. | import org.jboss.soa.esb.message.Message; | import org.jboss.soa.esb.message.format.MessageType; | | #declare any global variables here | global java.util.List destinationServices; | | expander JBossESB.dsl | | rule "Routing Rule - XML based message" | | when | xmlContentMatches "/PurchaseOrder" | then | System.out.println("JBoss_XML"); | destinationServices.add("test_category:JBOSS_XMLDestination"); | end | The DSL: | #JBossESB Content Based Routing DSL | [when]xmlContentMatches "{xpath}"=msg : Message( type == MessageType.JBOSS_XML ) and eval( org.jboss.soa.esb.services.routing.cbr.DslHelper.xmlContentMatches(msg, "{xpath}") ) | [when]xmlContentEquals "{xpath}", "{value}"=msg : Message( type == MessageType.JBOSS_XML ) and eval( org.jboss.soa.esb.services.routing.cbr.DslHelper.xmlContentEquals(msg, "{xpath}", "{value}") ) | Helper class that does the actual XPath matching: | package org.jboss.soa.esb.services.routing.cbr; | | import java.io.ByteArrayInputStream; | | import javax.xml.xpath.XPath; | import javax.xml.xpath.XPathConstants; | import javax.xml.xpath.XPathExpressionException; | import javax.xml.xpath.XPathFactory; | | import org.jboss.soa.esb.message.Message; | import org.xml.sax.InputSource; | | public class DslHelper { | private static XPathFactory xpf = XPathFactory.newInstance(); | | public static boolean xmlContentMatches(Message msg, String xpathExp) throws XPathExpressionException { | XPath xpath = xpf.newXPath(); | InputSource inputSource = new InputSource(new ByteArrayInputStream(msg.getBody().getContents())); | Object node = xpath.evaluate(xpathExp, inputSource, XPathConstants.NODE); | return node != null; | } | | public static boolean xmlContentEquals(Message msg, String xpathExp, String value) throws XPathExpressionException { | XPath xpath = xpf.newXPath(); | InputSource inputSource = new InputSource(new ByteArrayInputStream(msg.getBody().getContents())); | String node = (String) xpath.evaluate(xpathExp, inputSource, XPathConstants.STRING); | return value.equals(node); | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3982752#3982752 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3982752

[Deployers on JBoss (Deployers/JBoss)] - Re: Dynamically reordering of deployers

by dimitris＠jboss.org

Not exactly dynamic behaviour but you can set the relative order to webDeployer.getRelativeOrder() - 1 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3982738#3982738 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3982738

[Design of JBoss jBPM] - Re: Web console enhancements

by kukeltje

"david.lloyd(a)jboss.com" wrote : | | "tom.baeyens(a)jboss.com" wrote : One thing i would do different was the filtercriteria on the task lists; i would put that underneath or at the right of the actual list. | Yeah, I debated about that one for a while, and I think I tend to agree. What about at the top? So you can type just below the headers to filter... Small other issue. the console 'project' complains about not finding the javax.xml.stream package, but eclipse does compile the class and the ant task works to. Closing, opening the project does not help, anybody seen this?

[Deployers on JBoss (Deployers/JBoss)] - Re: Dynamically reordering of deployers

by scott.stark＠jboss.org

Looking more at your code, no, this is not allowed. You are trying to change the order of another deployer. You can only set your order.

[Design the new POJO MicroContainer] - Added KernelLocator utility

by scott.stark＠jboss.org

I added a simple org.jboss.kernel.plugins.util.KernelLocator singleton that can be used to access the Kernel the KernelLocator is deployed to. When running under a security manager the KernelLocator.getKernel() caller will require a org.jboss.kernel.plugins.util.KernelLocatorPermission("kernel") permission.

by ddunkin

I don't think you need to use the XML rules. I'm looking into how this could be implemented in the new DSL method.

[Design of JBoss jBPM] - Re: execution transitions, data flow and other associations

by brittm

Tom, its my understanding that a Link in BPEL is simply a mechanism that sends a message and waits for a response. In other words, a wait state with a messaging structure defined. Of course, that can be used for synchronization purposes. What we need for sync without merge is something much more defined. Something that allows processes to 'subscribe' a node to a 'sync group' based on some common variable (like an order number), and then react to various conditions of that group as each participating node is executed. Configuration could allow participating nodes to react in different ways to various conditions within the sync group, such as: * If I'm the first to arrive, take my transition a. * If I'm not the first, take my transition b. * If I'm the last to arrive, take my transition c. * Or when the last participant has arrived, take my transition d. Done properly, this would allow for dynamic processes in which the definition doesn't need to know ahead of time how many instances (or what type of instances) will be participating in a sync group. This kind of dynamic behavior is huge. Probably within the next week or two I'll have something like this implemented orthagonally to jBPM, but of course, like Shared Subprocess, I'd love to see these concepts integrated into the project.

[Deployers on JBoss (Deployers/JBoss)] - Re: Dynamically reordering of deployers

by scott.stark＠jboss.org

Note that the default relativeOrder value (if your subclassing one of the Abstract* deployers) is not going to be 0. Are you sure you are even hitting this lookup code?
