WebLogic + JBuilder 开发的问题

[chenweionline]

我最近在学习《J2EE应用开发（WebLogic+JBuilder）》，第四章的WebLogic Server下有个JDBC开发实例，原例题操作的是JBuilder自带的数据库employee.jds，我现在把它改写成了操作Oracle数据库中的表emp。我按书中内容已经在WebLogic中设置好了连接池、数据源；在JBuilder中也配置了要使用的应用服务器信息并添加了Oracle的数据库驱动程序。我在JBuilder外启动WebLogic Server，再将执行类型设成Application，运行，得到结果正常；可是停止WebLogic Server后，我将执行类型设成Server，再运行，就报以下错误，为什么？怎么解决？执行类型设成Application或Server有什么区别？用JBuilder结合WebLogic开发，在JBuilder中也配置了要使用的应用服务器信息并添加了Oracle的数据库驱动程序，是不是就不需要在外面启动WebLogic Server？我初学J2EE，还盼详解，谢谢了。

你需要把你数据库的驱动程序添加到你的weblogic运行的你执行的那个文件中，其实不用再jb里面启动weblogic也是一样的，如果是你再jb里面启动的话就不能把你的jb关掉，也就是说不能把你服务器关掉，要是再外面的话就是可以的。如果你再jb里面启用服务器的话就不需要再外面再起了，因为这两个服务器是一样的。
