关于java调用存储过程，高手请指教小弟一下。。。！
java代码如下：package download.action;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.DataSource;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;


public class dbconnection extends Action{

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
Connection con =null;

DataSource ds = getDataSource(request, "datasource ");

con = ds.getConnection();

CallableStatement proc = null;

try {

proc = con.prepareCall( "{call YANGJIANP.reran01()} ");

boolean flag = proc.execute();

System.out.println(flag);

con.commit();

}catch(Exception e)

{
System.out.println(e.getMessage());

}finally {

try { proc.close(); }catch(SQLException e) {}

try { con.close(); }catch(SQLException e) {}
}

return null;
}
}

执行之后控制台信息如下：
2007/04/24 12:37:29 org.apache.struts.action.RequestProcessor process
情: Processing a 'POST ' for path '/dbconnection '
false
为什么执行没有错误，但是执行的结果却不正确，没有实现存储过程的方法。

[解决办法]
我也有类似的问题,UP
