I need help with the combining the pdf files.

 

I got the pdf files stored in dataabse as BLOBS.Iam reading those BLOBS as inputstreams and converting them to byte[] and putting them in a list.If it is one pdf ,iam able to view the pdf from the outputstream of the servlet response in the browser.If there are multiple pdfs,i want to combine them and show as one pdf file in the single servlet response.

 

 

I try to use the iText API for reading the byte[] in the pdfReader for concatenating them.Iam end up with an IO exception saying that Unknown Encryption type.Pleasee find the error as below and let me know if you could help me in this.

 

java.io.IOException: Unknown encryption type (4)
