copied!<p>Had you tried creating a .jar file manually instead of using Eclipse. Try the following steps, hopefully that might help :</p> <p>Considering that your directory structure looks like this : </p> <pre><code> TicTacToe(Your Project Name I mean) | | | src bin manifest.txt | | icons tictactoe </code></pre> <p>Now suppose that my main class is <code>BeginGame</code> inside package <code>tictactoe</code>, so I will write inside my manifest.txt file this thing : </p> <pre><code>Main-Class: tictactoe.BeginGame </code></pre> <p>Do remember the space between colons <code>:</code> and package name i.e. <code>tictactoe</code>, and immediately after <code>BeginGame</code> press Enter and save the file.</p> <p>Now on your command prompt go to the location of bin folder, I am describing my side as follows : </p> <pre><code>C:\Mine\Eclipse\TicTacToe\bin>jar -cfm ..\tictactoe.jar ..\manifest.txt tictactoe icons </code></pre> <ul> <li>Here the first argument i.e. <code>..\tictactoe.jar</code> is used to tell that create tictactoe.jar one level up, i.e. inside <code>TicTacToe Folder</code>.</li> <li>Second argument <code>..\manifest.txt</code> means that the manifest.txt file is located one level up, i.e. inside <code>TicTacToe Folder</code>.</li> <li>Third and Fourth arguments <code>tictactoe</code> and <code>icons</code> means, that add both these folders to the <code>.jar</code> file, since they are placed inside <code>bin</code> Folder so they are used as it is. Now Press Enter.</li> </ul> <p>Now try to run your .jar file so created inside the <code>Project Folder</code> (TicTacToe Folder, in my case). </p> <p>Hopefully this will work.</p>
