Hello Team,

I am new user of Dynamsoft Web Twain. I have downloaded the trail version 10.2 and a sample regarding Uploading scanned images to web server using JSP from the below link ( http://www.dynamsoft.com/Downloads/DownloadSample.aspx?DemoID=10 ). When I have used this sample in Windows 8.1 OS with Apache Tomcat server version 8.0, everything is working fine. File is getting uploaded and response is also received. But when I have used same code in Ubuntu 12.04 with Apache Tomcat 7.0.54 version and tested it in Windows 8, I am always getting error code as -2303 and error string as Upload Error though file is uploaded in given folder.

Can you please let me know what's wrong is going on?

Thanks,
Hari Krishna

Please double check and see if there is anything (any string) returned from your server-side. Our upload method is designed in this way: if empty string is returned from server after upload, it gives "successful"; however, if you send back any strings after upload, even though the file has been successfully sent to server-side, our SDK still reports an error.

In your case, it seems there is an un-empty string returned. You may check DWObject.HTTPPostResponseString for details.

Thanks,
