Under the heading of "can sesame do this"......

I'm looking for replacement options for a document indexing web application.  Basically it needs to do the following:

1) Read a directory on the local pc and display a list of files to be indexed.
2) Display the file (PDF) in the form.
3) User would fill out index fields including one set of cascading drop downs.
4) user submits document which starts a process to build a text file containing the index values and writes that file and the matching document out to a network share.

Other requirements:
1) Ability to validate employee information.  Basically user supplies a social security number and a process goes out, reads a DB2 table and returns the name that matches.
2) I'll think of more requirements after I post this I'm sure.

That's the nuts and bolts of it.....I'm pretty sure most of it could be done but I'm not 100% on the DB2 data verification.
