javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory

今天遇到了一个很郁闷的 问题，以下内容摘自

 哪位仁兄懂EJB3，我用InitialContext init = new InitialContext();
读取jndi.properties ，jboss中client包已经全部导入怎么还是不行。
我已经晕掉了，我用myeclipse6+jboss4.2

报异常：

 我晕啊，java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory后面带给空格就不能处理了，这个InitialContext 不能去空格

 

 

解决办法： jndiproperties的属性值后面不能带空格
