How to see if a file is written to diks from other process?

Hello!

I wonder if any one got a soloution for this problem.

I dynamically write a couple of Word-files to disk with WordApi.exe from a Servlet. It looks something like:

BatchWordProcessing bwp = new BatchWordProcessing();

    for(int i = 0; i < x; i++)
    {
        bwp.createNewDocumentFromTemplate(templateName);
        bwp.typeTextAtBookmark("bookmarkname", "A string");
        bwp.saveDocumentAs(newfilename);
    }

bwp.quitApplication();
bwp.exec();


The BatchWordProcessing is calling the WordApi.exe for the filesaveing_process.

The Servlet has almost always executed to its end before the WordApi.exe is done.

What I need to know is some waiting-process until all files is written to the disk. Cause at the end I would like to zip all the files and present a link to the zip-file with all the files written by WordApi.exe.

So if any one got some idea how to solve this.

Best regards
Fredrik
