Oracle8.17 Jbuilder5 tomcat3.2 jdk1.3 jsp程序
以下两段代码都提示以下错误
java.io.IOException: ORA-22920: 未锁定含有 LOB 值的行

第一段
        BLOB blob = (oracle.sql.BLOB)lRs.getBlob("b");
        File binaryFile = new File("e:\paper.jpg");
        System.out.println("paper.jpg length = " + binaryFile.length());
        FileInputStream instream = new FileInputStream(binaryFile);
        OutputStream outstream = blob.getBinaryOutputStream();

        int size = blob.getBufferSize();
        byte[] buffer = new byte[size];
        int length = -1;

        while ((length = instream.read(buffer)) != -1)
        outstream.write(buffer, 0, length);
        instream.close();
        outstream.close();


第二段
        OutputStream outstream = blob.getBinaryOutputStream();
        byte[] bAtt = "e:\paper.jpg".getBytes();
        outstream.write(bAtt,0,bAtt.length);
        outstream.close();
