从jsp页面定期调用Servlet（Java）

[英]Periodically call of a Servlet from jsp page (Java)

I have a problem and i don't know how to resolve it... 我有一个问题，我不知道如何解决...

I have 2 .dbf files with ~10000 records (geospatial informations) that i want to read from a jsp page, every time i read 200 records i have to send them to a servlet in some format (i haven't decided yet). 我有2个.dbf文件，它们具有〜10000个记录（地理空间信息），我想从jsp页面读取，每当我读取200条记录时，都必须将它们以某种格式发送到servlet（我尚未决定）。 The Servlet must save every record as a Document object in Google Appengine (the limit of 200 records is specified by Appengine api's). Servlet必须将每条记录保存为Google Appengine中的Document对象（200条记录的限制由Appengine api指定）。

I can't upload the file to server and read server-side cause of some AWT classes not supported by Appengine, then i tried to read the files client-side and send to server the parsed records but i don't know how i can do this. 我无法将文件上传到服务器并读取Appengine不支持的某些AWT类的服务器端原因，然后我尝试读取客户端文件并将已解析的记录发送到服务器，但是我不知道该怎么办做这个。

Someone have a solution to this problem? 有人对此问题有解决方案吗？

jsp , once complied, is nothing but a servlet . jsp一旦被编译，就只是一个servlet 。 That being said, you say: 话虽如此，你说：

I can't upload the file to server and read server-side cause of some AWT classes not supported by Appengine 我无法将文件上传到服务器，也无法读取服务器端AppEngine不支持的一些AWT类的原因

Once you finish reading 200 records, why not insert it into the appengine from the jsp itself. 阅读完200条记录后，为什么不从jsp本身将其插入到appengine 。 The jsp will run on the server either way. jsp将以任何一种方式在服务器上运行。
