[Solved] Images actually not uploading Ckfinder - Java

hi, i'm trying to integrate ckfinder with ckeditor for my client, issue i'm facing while trying the trail first is:

I downloaded ckeditor 4 and ckfinder 2.3 for java, installed as per documentaions instructions, ckeditor working fine. But ckfinder not. As i click on browse server, ckfinder appears, i can browse images and upload them, i see thumbnails for them in ckfinder window. but whn i select any image and it returns the image url to ckeditor, the image is not found.

I've checked the upload directory several times and no image is actually getting upload, but i can see thumbnails in ckfinder window. Also when i right click on thumbnails and choose view it says could not load image.

In short, i can browse and upload into ckfinder but images are not getting upload.

Please let me know if any common mistake i've done?
