<br />
u can have restrictions on the type of file to be uploaded to the server.(.exe...etc)<br />
For .txt file, u can also make some server side validation to check the extension.<br />

hello <br />
we want to creat file upload module using JSP/Servlets API. <br />
We only allow TXT type files to be uploaded through this module.<br />
There are about 200 trusted clients will access this module to upload <br />
there information that will be stored in DataBase after some validations.<br />
<br />
We have face some problems that are given bellow.<br />
<br />
Can we track file type before sending it to server?<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ie. Rec.doc rename to Rec.txt, should not upload.<br />
<br />
Can we track file contents to be uploaded are non harmfull?<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.e Rec.exe or Rec.dll rename as Rec.txt and upload it.<br />
Can we use anti virus tools using java?<br />
<br />
regards,<br />
Faisal<br />

FILE UPLOADING USING JSP

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
