jbossjvm外的java程序无法引用数据源


<use-java-context> - A boolean indicating if the jndi-name should be prefixed with java: which causes the DataSource to only be accessible from within the jboss server vm. The default is true.

Configuring a DataSource for remote usage
As of jboss-4.0.0 there is support for accessing a DataSource from a remote client. The one change that is necessary for the client to be able to lookup the DataSource from JNDI is to specify use-java-context=false as shown here:

<datasources>  <local-tx-datasource>    <jndi-name>GenericDS</jndi-name>    <use-java-context>false</use-java-context>    <connection-url>...</connection-url>...
This results in the DataSource being bound under the JNDI name "GenericDS" instead of the default of "java:/GenericDS" which restricts the lookup to the same VM as the jboss server.

当你指定<use-java-context>的值为false时,你就可以在jboss运行的VM外的VM上查找到这个DataSource.
这个属性默认为true 即默认情况下你是不可以在JBOSS的VM外来查找这个数据源.
