Body
Have a look at the <a href="http://commons.apache.org/compress/" rel="nofollow noreferrer">Apache Commons Compress</a> library, it provides the functionality you need. Of course "erickson" is right with his comment to your question. You will need the file content and not the <code>java.io.File</code> object. In my example I assume that you have a method <code>byte[] getTheContentFormSomewhere(int fileNummer)</code> which returns the file content (in memory) for the fileNummer-th file. -- Of course this function is poor design, but it is only for illustration. It should work a bit like this: <pre><code>void compress(final OutputStream out) { ZipOutputStream zipOutputStream = new ZipOutputStream(out); zipOutputStream.setLevel(ZipOutputStream.STORED); for(int i = 0; i < 10; i++) { //of course you need the file content of the i-th file byte[] oneFileContent = getTheContentFormSomewhere(i); addOneFileToZipArchive(zipOutputStream, "file"+i+"."txt", oneFileContent); } zipOutputStream.close(); } void addOneFileToZipArchive(final ZipOutputStream zipStream, String fileName, byte[] content) { ZipArchiveEntry zipEntry = new ZipArchiveEntry(fileName); zipStream.putNextEntry(zipEntry); zipStream.write(pdfBytes); zipStream.closeEntry(); } </code></pre> Snipets of your http controller: <pre><code>HttpServletResponse response ... response.setContentType("application/zip"); response.addHeader("Content-Disposition", "attachment; filename=\"compress.zip\""); response.addHeader("Content-Transfer-Encoding", "binary"); ByteArrayOutputStream outputBuffer = new ByteArrayOutputStream(); compress(outputBuffer); response.getOutputStream().write(outputBuffer.toByteArray()); response.getOutputStream().flush(); outputBuffer.close(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
