问题自己解决了,以前就把weblogic.jar放在项目中,这样不行,还缺少一个jrmpclient.jar这样的jar包,但你回答了,答案就给你了

Answer 1

是不是配置有问题，建议检查数据源配置
和访问代码。下面的参考一下：
1：首先在weblogic 下配置好数据源jdbc/testDATASource
2: 调用代码：
/**
* 根据数据源名称获取数据库连接对象, 这里将保证只存在一个活动的连接对象
* @param dataSource 数据源名称
*/
protected Connection getConnection(String dataSource) {
try {
//Hashtable has=new Hashtable();
// has.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory ");
// has.put(Context.PROVIDER_URL, "http://192.168.0.166:7001 ");
if (ds == null) {

Context myContext = new InitialContext();//has
ds = (javax.sql.DataSource) myContext.lookup(dataSource);//"java:comp/env/"+
}
//如果conn已经创建并且已经关闭, 则先置null
if (conn != null) {
if (conn.isClosed()) {
conn = null;
}
}
if (conn == null) {
conn = ds.getConnection();
}
}catch (NamingException ne) {
System.out.println("Naming exception occured.");
ne.printStackTrace();
}catch (SQLException se) {
System.out.println("Can't get connection from data source.");
se.printStackTrace();
}catch (Exception e) {
System.out.println("Unknown error in getConnection().");
e.printStackTrace();
}

return conn;
}
3：同时注意 数据库驱动 jar 包 放到 bea\weblogic81\server\lib\目录下
4:注意其他的版本 如jdk 和相关javax冲突问题
