什么是 JBOSS-“Java 不允许使用空名称段”错误

Question

我是 JBOSS 开发的新手，想从 Eclipse 运行一个项目，但我收到 “Java 不允许空名称段” 错误。我知道当我们的 jndi 资源名称为空时会出现此类错误，但在这种情况下，它指定为 "env" 而不是 "java" ，在我的情况下。在下面发布我的堆栈跟踪。我使用的是 JBOSS 7.1 版本。

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。

请指导我。提前致谢。

我需要从standalone.xml 中提到的数据源中删除java:/ 前缀。它得到了解决。因为在persistance.xml 中没有那个前缀。
