Read and Edit a PDF File

Dear Friends,

I would like to know if it is possible to read and edit the same pdf file using Java. ie my PDF file named "Sample.pdf" has contents like

First Name = &F_NAME

Last Name =&L_NAME

what I want is to parse the Sample.pdf file and look for &F_NAME and replace it with "Jacob" and &L_NAME and replace it with "Abraham" so that the contents within that pdf file look like

First Name = Jacob

Last Name =Abraham

Please let me know if it is possible to do like this. All suggestions are welcome. Thanks in advance.
