but the client can uploading any size of file. that receiving after, without any defect of the picture, and adjusting to the 190X200 size.

Hi

I had to solve that kind of problem once.

Since I used a server without any native graphics resource (headless server), I choosed to use PJA Toolkit but you probably don't need it.

Anyway, you will find a sample code about how to generate a compressed picture (thumb) in this java class using extra API such as java.awt, javax.swing, com.sun.image.codec.jpeg etc..

We used java jdk image toolkit to compress the images(thumbnails). But make sure if you are working with web applications. If you do more compression or decompression of large images , lot of heap is used to do these kind of operations. And at one point you will be having OutOfMemory Errors.
