javax.mail.internet.ParseException: Unbalanced quoted string 这么解决啊大家，给点意见讨论一下

public void saveAttachMent(Part part) throws Exception {
        String fileName = "";
        String disposition = "";
        if (part.isMimeType("multipart/*")) {
            Multipart mp = (Multipart) part.getContent();

             for (int i = 0; i < mp.getCount(); i++) {
                BodyPart mpart = mp.getBodyPart(i);

                disposition = mpart.getDisposition();//这里就报javax.mail.internet.ParseException: Unbalanced quoted string 打印出来的mp.getContentType()是=======multipart/report;
boundary="----=_Part_2_16900263.1249265548460";
report-type=delivery-status
==*****=====text/plain; charset=us-ascii
==*****=====message/delivery-status; name=status.dat
==*****=====message/rfc822; name="

                //if(mbp!=null)disposition=mbp.getDisposition();
               if ((disposition != null) && ((disposition.equals(Part.ATTACHMENT)) ||
                        (disposition.equals(Part.INLINE)))) {
                    fileName = mpart.getFileName();
                    //fj.add(fileName);
                    if (fileName != null) {
                        if (fileName.toLowerCase().indexOf("gbk") != -1 || fileName.toLowerCase().indexOf("GBK") != -1) {
                            fileName = MimeUtility.decodeText(fileName);
                        }
                    }
                    saveFile(fileName, mpart.getInputStream());
                } else if (mpart.isMimeType("multipart/*")) {
                    saveAttachMent(mpart);
                } else {
                    fileName = mpart.getFileName();
                    if ((fileName != null) && (fileName.toLowerCase().indexOf("GB2312") != -1)) {
                        fileName = MimeUtility.decodeText(fileName);
                        saveFile(fileName, mpart.getInputStream());
                    //  fj.add(filename2);
                    }
                }
            }
        } else if (part.isMimeType("message/rfc822")) {
            saveAttachMent((Part) part.getContent());
        }

    //  return fileName;
    }
--------------------编程问答-------------------- 加载的jar 包不一样.
检查是否在一个应用中有多个mail组件，导致你的jar包未先加载，
可以使用
System.out.println(javax.mail.internet.MimeMessage.class.getResource(""));
将当前调用的类及路径都打印出来看看，比如在eclipse中调用的就是插件中的mail组件 --------------------编程问答-------------------- 大神，我也在写个mail的功能，调试的收报错如下：

怎么解决啊？ --------------------编程问答-------------------- Unbalanced quoted string
英文的直意是：引号未平衡。也就是你代码某个地方的引号少写了一半

补充：Java ,  Web 开发
