我的任务
分享路人甲啊，怎么还不见你啊~~~~~~~~~~~~~~~~送500分
我用jspsmartupload处理上传，大家知道上面有例子，是关于mysql的，我用的是oracle，所以把驱动改了，表的结构和字段一模一样。如下：
<%@ page language="java" import="java.sql.*,oracle.sql.*,com.jspsmart.upload.*"%>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" />
<HTML>
<BODY BGCOLOR="white">
<H1>jspSmartUpload : Sample 4</H1>
<HR>
<%
//ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_UPDATABLE
// Variables
int count=0;
// Connect to the database
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@www.ffff.org:1521:oracle","fff","fff");
// SQL Request
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("SELECT * FROM TFILES WHERE ID=1");
// if the resultset is not null
if (rs.next()){
// Initialization
mySmartUpload.initialize(pageContext);
// Upload
mySmartUpload.upload();
// upload file in the DB if this file is not missing
if (!mySmartUpload.getFiles().getFile(0).isMissing()){
try {
rs.updateString("FILENAME",mySmartUpload.getFiles().getFile(0).getFileName());
// Add the current file in the DB field
mySmartUpload.getFiles().getFile(0).fileToField(rs,"FILE");
// Update
rs.updateRow();
count++;
} catch(Exception e) {
out.println("An error occurs : " + e.toString());
}
}
}
// Display the number of files uploaded
out.println(count + " file(s) uploaded in the database.");
rs.close();
stmt.close();
con.close();
%>
</BODY>
</HTML>
异常如下：
An error occurs : java.sql.SQLException: Invalid operation for read only resultset: updateString 0 file(s) uploaded in the database
怎么回事？明明Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_UPDATABLE);
原来的例子（mysql）用得很顺利。
被蹩得没法子了，大家能体会我的心情吧，帮我分析一下，看是什么问题，
我以为是驱动不支持结果集可修改，可换了两个还是劳样子，是这问题吗？
如果谁的办法能帮我解决，我发毒誓给至少500，发新贴给！！！当然
空口无凭，但请相信我！！！！！！！！！！！
