什么是JBOSS-"Java不允许使用空名称段"错误 [英] What is JBOSS- "Empty name segment is not allowed for java" error

问题描述

我是JBOSS开发的新手，正在尝试从Eclipse运行项目，但出现"Java不允许使用空名称段" 错误.我知道当我们的jndi资源名称为空时会出现这种错误，但是在这种情况下，它指定为"env" 而不是"java" .在下面发布我的stacktrace.我正在使用JBOSS 7.1版本.

I am newbee to JBOSS developement and tring to run a project from eclipse but I am getting "Empty name segment is not allowed for java" error. I know such error comes when our jndi resource name is empty but in such case it specifies as "env" and not "java" which is in my case. Posting my stacktrace below. I am using JBOSS 7.1 version.

我看到一个警告说JBAS011001: Could not resolve resource-env-ref java:/TransactionManager，但不认为错误是由它引起的.

I see one warning saying that JBAS011001: Could not resolve resource-env-ref java:/TransactionManager but dont think error is caused by it.

请指导我.预先感谢.

推荐答案

我需要从standalone.xml中提到的数据源中删除java:/前缀.解决了因为在persistance.xml中没有该前缀.

I need to remove java:/ prefix from the datasources mentioned in standalone.xml. It got solved. Because in persistance.xml it was without that prefix.
