如何通过struts以oci协议将文件上传到oracle数据库的blob字段

如何通过struts以oci协议将文件上传到oracle数据库的blob字段

ss文件如下：

import java.io.*;

import java.sql.*;

import java.util.Date ;

import oracle.sql.*;

import javax.servlet.http.*;

import org.apache.struts.action.*;

import org.apache.struts.upload.*;

public class UploadAction extends Action

{

public ActionForward execute(ActionMapping mapping,

ActionForm form,

HttpServletRequest request,

HttpServletResponse response)

throws Exception {

if (form instanceof UploadForm) {

Date date = new Date();

System.out.println("-------------File Upload Begins-------------------") ;

UploadForm theForm = (UploadForm) form;

过struts的FormFile类来获得上传的文件，前台jsp页面对应的代码

html:file property="theFile" />

FormFile file = theForm.getTheFile();

Connection conn = null;
