I fixed the last problem and now I can import org.apache.poi completely.

But now I have 3 problems:

1) I don't know how the Methods of classes "PictureTable" and "Picture" work? if you have an simple example or code about them please give me...!

2) I can extract the text out of doc.but it is just for english.(for example in iranian or arabic it dosen't work)

3) how I can recognize the subjects(I want to hold them separate)

please help me...
