java - 在 JBoss 7.1.1 中使用 EJB 3.1 调用 Struts 2 Action 时获得 Struts 报告

Question

我开发了一个EJB项目并将其打包为jar文件，然后我使用Struts 2.1.15.2创建了一个Web项目，并将jar文件放置在WebRoot/WEB-INF/lib目录中。我打算使用struts2-ejb3-plugin来集成它们。但是当我在Action中调用execute方法时，我得到了这样的Struts问题报告。

堆栈跟踪:

You are seeing this page because development mode is enabled. Development mode, or `devMode`, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:

  struts.devMode=false
in your WEB-INF/classes/struts.properties file.

这是struts2-ejb3-plugin.properties:

ENCPath=java:comp/env/
#ENCPath=ejb:/tobaccoWeb//
ejbContainer=cn.agrael.struts.plugin.ejb3.JbossApplicationServer
isParseResource=true
isParseEJB=true
earFileBaseName=
remote=remote
local=local

和jboss-ejb-client.properties:

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port = 4447

jndi.properties:

remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

您不应该这样做，而是创建一个 Java EE 项目并分别为 EJB 和 Web 添加模块。部署 Ear 后，JBoss 将发布 EJB，以便其他模块(即 Web 模块)可以访问它们的 JNDI。
