嵌入式JBoss EAP 6 / AS 7入门

本文介绍了嵌入式JBoss EAP 6 / AS 7入门的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述 29岁程序员，3月因学历无情被辞！我正在使用规范（JSR 318：Enterprise JavaBeans，版本3.1，第22章：可嵌入的用法）中描述的EJBContainer.createEJBContainer API尝试可嵌入的JBoss，不是任何各种前辈。概述正常调用主方法时，会话Bean调用成功。但是似乎存在一些类加载问题，因为 java：jboss / UserTransaction 中的JNDI对象无法转换为javax.transaction.UserTransaction。所以我想 JBoss模块的类加载魔术在这里是必需的。经过我的尝试，createEJBContainer找不到任何EJBContainerProviders并抛出EJBException。请注意，并非我所有的问题都需要阅读所有后续内容。细节。因此，如果这本书太多了，请看看问题部分。环境 JBoss AS 7.1.1.Final（jboss-as-7.1.1.Final .zip，仅在standalone.xml中更改了仅记录conf的conf）。（最初是实际目标环境的JBoss EAP 6.0.1 GA-相同的问题） Oracle JDK 1.7.0_11 Windows 7 Prof 64位详细信息无状态会话bean 包test.helloworld.impl;

But there seem to be some classloading issues, because the JNDI object at "java:jboss/UserTransaction" cannot be cast to javax.transaction.UserTransaction.So i guess the classloading magic of JBoss Modules is required here. With my attempts at that, createEJBContainer does not find any EJBContainerProviders and throws an EJBException.Note that not all my questions require reading all subsequent details. So if this is too much to read, please have a look at the questions section nevertheless.

And both could participate in the same transaction (e.g. JDBC code starts tx with java.sql.Connection.setAutoCommit(false), then calls EJB with TransactionAttributeType.REQUIRED)?Can someone point me to some documentation? All i find is about the older stuff with JBoss specific API, not the standard EJB 3.1 way.Preferably, documentation how to use without any test frameworks, since i'm evaluating this for production use.Thanks for reading all (or part of :-) this! 解决方案 I found the solution for the JBoss Modules way, after remembering that i had read that META-INF/services need to be imported explicitly. So, the client's module.xml needs a services="import" and now looks like this:C:\eclipse\projects\HelloWorldSlSB-Client\rt\modules\test\helloworld\client\main\module.xml:<?xml version="1.0" encoding="ISO-8859-1"?><module xmlns="urn:jboss:module:1.1" name="test.helloworld.client"> <main-class name="test.helloworld.client.HelloWorldEmbeddedEjbTestClient"/> <resources> <resource-root path="HelloWorldSlSB-Client.jar"/> </resources> <dependencies> <module name="javax.api"/> <module name="javax.ejb.api"/> <module name="org.jboss.as.embedded" services="import"/> <module name="org.jboss.logmanager"/> <module name="test.helloworld"/> </dependencies></module>Besides, an error message told me to set system property java.util.logging.manager to org.jboss.logmanager.LogManager, so i added a corresponding -D VM argument. Then came ClassNotFoundException: org.jboss.logmanager.LogManager, so i added the logmanager dependency above.Only putting the EJB jar into the createEJBContainer Map argument was not sufficient for the client to see it, so it seems the EJB must also be a module which the client can explicitely depend on (<module name="test.helloworld"/> above). So i moved HelloWorld-API.jar and HelloWorld-EJB.jar to directory modulePath/test/helloworld/main/ (i.e. C:\eclipse\projects\HelloWorldSlSB-Client\rt\modules\test\helloworld\main), changed the path in new File("./HelloWorld-EJB.jar") accordingly, and added a module.xml for them:C:\eclipse\projects\HelloWorldSlSB-Client\rt\modules\test\helloworld\main\module.xml:<?xml version="1.0" encoding="ISO-8859-1"?><module xmlns="urn:jboss:module:1.1" name="test.helloworld"> <resources> <resource-root path="HelloWorld-API.jar"/> <resource-root path="HelloWorld-EJB.jar"/> </resources></module>I removed test/helloworld/api/HelloWorld.class from the EJB jar. Not necessary, but maybe cleaner.Edit 2013-02-27:Found a simpler working invocation, still using org.jboss.modules.Main, but with the EJB deployed as we'll probably do for the non-embedded use and no module.xml files required. And the no-arg createEJBContainer() is now sufficient, as i included the EJB jar in the -cp argument instead.%JBOSS_HOME%\standalone\deployments containsHelloWorld-API.jarHelloWorld-EJB.jarHelloWorld-EJB.jar:META-INF/MANIFEST.MFMETA-INF/jboss-deployment-structure.xmltest/helloworld/impl/HelloWorldBean.classHelloWorld-EJB.jar:META-INF/jboss-deployment-structure.xml:<?xml version="1.0" encoding="ISO-8859-1"?><jboss-deployment-structure> <deployment> <dependencies> <module name="deployment.HelloWorld-API.jar"/> </dependencies> <exclusions> <module name="Classpath"/> </exclusions> </deployment></jboss-deployment-structure>Invocation:C:\java\jdk1.7\bin\java -Xmx512m -XX:MaxPermSize=256m -Duser.language=en-Djboss.home=c:/java/jboss-as-7 -Djboss.home.dir=c:/java/jboss-as-7-Djava.util.logging.manager=org.jboss.logmanager.LogManager-classpath "C:\java\jboss-as-7\jboss-modules.jar"org.jboss.modules.Main-mp "C:\java\jboss-as-7\modules"-dep "javax.ejb.api, org.jboss.as.embedded, org.jboss.logmanager"-cp "C:\eclipse\output\HelloWorldSlSB-Client;C:\java\jboss-as-7\standalone\deployments\HelloWorld-API.jar;C:\java\jboss-as-7\standalone\deployments\HelloWorld-EJB.jar"test.helloworld.client.HelloWorldEmbeddedEjbTestClientDirectory C:\eclipse\projects\HelloWorldSlSB-Client\rt\modules: empty, no longer used.End of edit 2013-02-27Remaining questionsIf someone knows how to get the direct invocation without org.jboss.modules.Main running, i'd still like to know.Documentation links are still very welcome.The UserTransaction / JDBC questionBTW, maybe someone with enough reputation could add a tag like jboss-modules? 这篇关于嵌入式JBoss EAP 6 / AS 7入门的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！上岸，阿里云！
