                String strSql = "insert into test(id,name,content) values('" + id + "','" + fileName + "',empty_blob())";
                stmt.execute(strSql);
                ResultSet rs = stmt.executeQuery("select content from zyw_test where id='" + id + "' for update ");
                if (rs.next()) {

                    OutputStream outStream = blob.getBinaryOutputStream();
                    inStream.read(bytes);
                    outStream.write(bytes);
                    outStream.flush();
                    stmt.execute("commit");
                    outStream.close();
                }
                inStream.close();
                stmt.close();
                if(file!=null)//删除文件
                    file.delete();
                out.println("upload sucess");
            } else {
                out.println("no file");
            }
        } catch (Exception ex) {
            if(file!=null)
                file.delete();
            out.println("upload fail");
            ex.printStackTrace();
        }
        System.out.println("============UpLoad end=============");
    }
}
自己修改一下就可以用了

楼上的朋友，我想要关于struts的例子，这个例子我已经在网上找到了。就是在jsp页面上用<html:file......>的，在action里处理文件上传的例子。哪位有的，给我一份。[email protected]

为什么要用jspsmartupload呢？对内存不好啊。建议你看看struts包里自带的，你看看struts-upload.war吧（就在你下载回的struts包里就有）。很简单的。
