访问测试时发生以下错误.jsp。
Following error occurred while accessing test.jsp.

我不想放em> jboss-client.jar 在Test.ear - > Test.war - > WEB-INF / lib中,因为有多个EAR可以访问Test.java 类。
I don't want to put jboss-client.jar in Test.ear --> Test.war --> WEB-INF/lib, as there are multiple EARs which will access Test.java class.
推荐答案
您尝试加载一些本地数据源时,您的JNDI代码用于远程调用。
您可以使用jboss-deployment-structure.xml文件在jboss客户端模块上添加依赖关系。
Your JNDI code is for remote call while you are trying to load some local datasource.You may add a dependency on the jboss client module with a jboss-deployment-structure.xml file.
