Replacing Characters in File

Question

Ok, here is my situation. I am using a 3rd party application to upload files to my server. I am using another 3rd party application to index and search the files. The problem I am having is that the searching application will only recognize files without spaces in them, and most of the 3500 files that are going to be uploaded have spaces in them and I don't want to have to go through all of the files and rename them. What I am trying to do is to replace the space with an '_'. Here is the code that does the uploading.
<%
              Hashtable files = mrequest.getFiles();
                if ( (files != null) && (!files.isEmpty()) )
                    UploadFile file = (UploadFile) files.get("uploadfile");
     String filename = file.getFileName();
     pageContext.setAttribute("filename", filename);
                    // Uses the bean now to store specified by jsp:setProperty at the top.
                    upBean.store(mrequest, "uploadfile");
%>I know there is the replace(char,char) but I can't seem to get this to work. Any help would be greatly appreciated.

Answer 1

The replace commond itself is fairly simple
filename = filename.replace(' ', '_')
But you have to tell it to save the file using this new name.
is that what the pageContext setAttribute() call was for?
You might have to do
file.setFileName(filename);
Is this hashtable a table of all the files? Then you need to iterate through the map and update each entry.
