Question

我无法进行查找

项目结构：动态Web项目（gss-web）和EJB项目（gss-ejb）在.ear（gss-ea）中一起部署到jboss 6服务器上

例外： javax.naming.NamingException：无法取消引用对象[根异常是javax.naming.NameNotFoundException：gss-ea未绑定]

代码 - 来自我的Web项目中的托管bean：

InitialContext ctx = new InitialContext( );
return ( CodesService )ctx.lookup( "java:/global/gss-ea/gss-ejb/CodesBean" );

非常感谢任何帮助。提前谢谢！

Answer 1

尝试：

return ( CodesService )ctx.lookup( "java:global/gss-ea/gss-ejb/CodesBean" );

注意：“global”之前没有“/”。

您是否检查过jmx控制台以查看是否正确部署了ejb。我认为您用于查找的名称不正确。它的ejb名称通常附加本地或远程。快速查看jmx控制台将为您提供正确的名称。

话虽如此，如果你使用的是ejb 3.x，你不必也不应该像这样查找ejb。只需使用@Ejb注释将Ejb注入到servlet中。

如果您使用的是Ejb3.1，则可以在战争中直接打包ejb。
