Open Source Document Management System | OpenKM

I was just wondering if its possible to edit files in openkm programmatically for example splitting pdf files? I know it can be done in a workflow but can it be implemented in a servlet? Is it best to just use other editing software? Any suggestions.

better if you explain us the problem that you want to solve, and then we can give to you some possible solutions.

I want to split a pdf file using a tab document extension and storing the split files in the current folder open in the filebrowser

That's seems not trivial. Let's talk something more about it I would like image the screen. How have you imagine it ?

On pdf preview tab, the problem is that really you're seend a swf, in that scenario you can not doing any type of edition.
You consider something easy like indicating number of pages ? or something more complex like indicating page and some text to page some text ?

I would like to use a tab document extension possible the preview tab and grab the page numbers from a TextBox and generate a pdf file with only the pages indicated by the user.

That can be done without major problems

You can contact with us for doing it http://www.openkm.com/Contact and refer to this post
Or take a look at http://wiki.openkm.com/index.php/Extension_Guide and here http://wiki.openkm.com/index.php/Developer_Guide and do yourself

Some last couple questions. Does the get function from the document service return the content of the file? Also, there is no create method in the document service how would I create the file dynamically.

You must create your own a servlet for it. Take a look at FileUploadServlet.java and DocumentServlet.java
