NoClassDefFoundError: oracle/sql/ClobDBAccess！！困绕好多日子了，向zez前辈及各位熟悉weblogic+oracle应用的大侠求救！！！一定送分

[Jiemi]

源码很简单，只是搜索weblogic中配好的oracle8i数据源，如果只是完成这个，程序不会出异常，但是如果从数据源调用getConnection()试图获取连接时，就会抛出异常！！！

源代码：


package testoracledatasource;

import javax.naming.InitialContext;
import javax.naming.NamingException;
import java.util.Hashtable;
import javax.naming.Context;
import javax.sql.ConnectionPoolDataSource;
import javax.sql.PooledConnection;
import java.sql.SQLException;
import javax.sql.DataSource;

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

Connection conn=ds.getConnection();//这里出错！！
System.out.println("Success!");
}

System.out.println("NamingException:"+ne.getMessage());
}
catch(SQLException se)
{
System.out.println("SQLException: "+se.getMessage());
}
}

。。。。。。。。。。。。。
（余下的太长，省略。。。）

[javahui]

把驱动改成jar后缀加到weblogic\jdk1.3.1\jre\lib\ext下面，
要么修改setEnv.cmd里的classpath也可以。

[zez]

可惜,我没用过orcale.看你的错误好像和orcale驱动有关...
只能提示一下你
DataSource ds=(DataSource)ctx.lookup("JBMSOracleDataSource");
是Tx DataSource ,且jndi name 就是JBMSOracleDataSource

------------------------------------------------------
我们还年轻牛奶会有的奶牛也会有的
可天天在 csdn 混这些会有吗 ??

[Jiemi]

谢谢两位前辈or大侠，我今晚要试试先

[zhaozk]

你本志的stub不在classpath下面
