作为测试，你可以尝试jdbc / __ default作为查找字符串吗？对于我的数据源，我使用我指定的jndi名称查找它们，总是使用模式jdbc / MyDataSourceName。

@Resource（lookup =jdbc / MyDataSourceName ） 效果很好。从来没有尝试查找默认ds，特别是不通过java：全局命名空间。

I'm having trouble trying to use the @Resource annotation with Java EE 6 and Glassfish 3.1 (embedded). I want to look up a JNDI datasource, so I'm trying to get it working with the default datasource in Glassfish. In my code I have:

@Resource(lookup = "java:global/env/jdbc/__default")
DataSource dataSource;

It compiles fine. I'm using Maven + the advice here.

However, when I deploy my .war I always get the following error:

WARNING: Incorrect @Resource annotation class definition - missing lookup attribute
  symbol: FIELD
  location: javax.sql.DataSource ResourceLookup.dataSource

It's such a simple example that I'd be extremely surprised if it were a bug. I must be doing something wrong. Any ideas?

As a test, can you try "jdbc/__default" as the lookup string? For my datasources I look them up using a jndi name I have specified, always with the pattern "jdbc/MyDataSourceName".

@Resource(lookup="jdbc/MyDataSourceName") works well. Never tried to look up the default ds, particularly not through the java:global namespace.
