Thanks Mike,

You are right! I have just changed the folder name to an appropriate value and my problem got sorted out. And regarding generation of thumbnails, in the example code the scImageThumbnail is defined to have mime type as image/png, so when I upload an image document, there thumbnail are generated. But same I want to achieve for the other mime types like text/plain or application/pdf. I have added the bean declaration for the same by using just copy paste of the existing bean declaration. But it is not working and the thumbnails are being generated for images only. The xml file is given below for reference:

What happens when you call newDoc.createThumbnail(); with the other thumbnail types?
