Re: redirecting uploaded files in tomcat5

[Emerson Cargnin]

If I understood your question, you should have a servlet or equivalent 
framework that gives you one (struts,webworks, etc), that in its doPost 
method you i'll give the treatment of the uploaded file. I think that 
you can use upload commons subproject 
(http://jakarta.apache.org/commons/fileupload/) that does the hard work 
to treat upload of multiple files along with other form elements...

Hi Tom,

Thanks so much!

Which existing file would I insert this code (or would I have to create a new 
file then place this file in some Tomcat subdirectory??)  And are srcDir and 
dstDir arbitary folder names?

Thanks so much - I'm a newbie with this.

Kay,

What you need to do is copy or move the directories (on the same
machine) e.g.
/**
* Copies all files under srcDir to dstDir, if dstDir does not exist, it
* will be created.
*/
   public void copyDirectory(File srcDir, File dstDir) throws
IOException {
       if (srcDir.isDirectory()) {
           if (!dstDir.exists()) {
               dstDir.mkdir();
           }
   
           String[] children = srcDir.list();
           for (int i=0; i<children.length; i++) {
               copyDirectory(new File(srcDir, children[i]),
                                    new File(dstDir, children[i]));
           }
       } else {
           copy(srcDir, dstDir);
       }
   }

// Copies src file to dst file.
   // If the dst file does not exist, it is created
   void copy(File src, File dst) throws IOException {
       InputStream in = new FileInputStream(src);
       OutputStream out = new FileOutputStream(dst);
   
       // Transfer bytes from in to out
       byte[] buf = new byte[1024];
       int len;
       while ((len = in.read(buf)) > 0) {
           out.write(buf, 0, len);
       }
       in.close();
       out.close();
   }

Now if you have to copy a file to another computer, take a look at using
an ftp client and redirecting it (using a 'put') to another computer.
You may even look at using a native method via jni for doing your file
transfer. Have a look here:

Hi,

After I get files uploaded into the webapp folder of Tomcat5, how can I 
redirect them to be located/copied/moved OUTSIDE of the Tomcat folders?
(and 
possibly send them to other machines)

Thanks,
Kay
