copied!<p>You could either make <code>/</code> writable by your app server (which doesn't seem like a great idea to me) or store your uploaded files in another writable location.</p> <pre><code>File uploadedFile = new File(UPLOAD_DIRECTORY + fileName); File uploadedFile = new File("/"+fileName); </code></pre> <p>You also appear to be trying to declare <code>uploadedFile</code> twice. From the error, it looks like either <code>UPLOAD_DIRECTORY</code> is <code>/</code> or you're actually using the second line. Perhaps you just need to supply the right location in <code>UPLOAD_DIRECTORY</code>?</p> <p>To answer your comment-question about Java policy files:</p> <p>From <a href="http://java.sun.com/developer/onlineTraining/Programming/JDCBook/appA.html#over" rel="nofollow">Security and Permissions</a> on java.sun.com:</p> <blockquote> <p>There is one policy file for Java platform installation (system) and an optional policy file for each user. The system policy file is in {java.home}/lib/security/java.policy, and the user policy file is in each user's home directory. The system and user policy files are combined. So for example,there could be a system policy file with very few permissions granted to all users on the system, and individual policy files granting additional permissions to certain users.</p> </blockquote> <p>See the <a href="http://java.sun.com/developer/onlineTraining/Programming/JDCBook/appA.html#FilePermission" rel="nofollow">File Permission</a> section for setting file system permissions in the policy file.</p> <p>And to reiterate my own comment, you'll also want to pay attention to file system permissions in the OS, control of which will depend on the OS you're using.</p>
