高手请进，《Enterprise JavaBeans》第一个bean的发布问题！

hpcczq 2003-09-10 12:29:23

我用的是Weblogic7.0+Jbuilder9.0+SqlServer2000，数据库中建了SQL Server Connection Pool 和 SQLServer Tx Data Source。
按《Enterprise JavaBeans》第四章的内容做，4个class文件和ejb-jar.xml打包生成的cabin.jar放置在F:\bea\user_projects\mydomain\applications目录中，启动Weblogic时出错。
出错信息如下：
<2003-9-10 下午12时11分26秒> <Error> <Deployer> <149027> <Unable to activate app
lication, _appsdir_cabin_jar, from source, F:\bea\user_projects\mydomain\applica
tions\cabin.jar. Reason: No deployment found at F:\bea\user_projects\mydomain\ap
plications\cabin.jar.>

配置描述器内容如下：
