copied!<p>The error was the first line of "saveResource()":</p> <pre><code>InputStream stream = this.getClass().getResourceAsStream(fromFile); </code></pre> <p>Here, "stream" was always null. Here is the way to solve this (using Eclipse):</p> <ol> <li><p>Create a new <strong>package</strong> in <strong>src</strong> (let's call it <em>resources</em>).</p></li> <li><p>Create a new <strong>folder</strong> in your <strong>package</strong> (let's call it <em>myPictures</em>)</p></li> <li><p>Create more folders if you want. I'll create a new folder inside <em>myPictures</em> and I'll call it <em>partyPictures</em></p></li> <li><p>Choose one of your folders and put the images (or whatever) inside. I'll have an image called <em>imageName.jpg</em> inside <em>partyPictures</em></p></li> <li><p>Then, go to the "Navigator", find your Proyect, and you will see that there is a folder called <em>bin</em>. Inside, you should see your packages organised in folders. </p></li> <li><p>Look for the folder inside <em>bin</em> that has the name of the package you created before (I'll have a folder called <em>resources</em>). Inside the folder you'll see a tree-view of the folders inside the package (the ones you created before).</p></li> <li><p>Look for your files. (I'll look for <em>resources/myPictures/partyPictures/imageName.jpg</em>)</p></li> <li><p>If it doesn't exist, <strong>InputStream stream = this.getClass().getResourceAsStream(fromFile);</strong> will always null. To fix this, copy the image (or whatever file) to the folder.</p></li> <li><p>Then use</p> <pre><code>String fromFile = "/resources/myPictures/partyPictures/imageName.jpg"; InputStream stream = this.getClass().getResourceAsStream(fromFile); </code></pre></li> <li><p>Change the String <strong>fromFile</strong> to your file's path, and always start with a <strong>/</strong>. Your code will look like this:</p></li> </ol> <p>String fromFile = "/<strong>packageName</strong>/ <strong>folderName</strong>/ <strong>fileName.extension</strong>";</p> <p>InputStream stream = this.getClass().getResourceAsStream(fromFile);</p> <h1>That should be it!</h1>
