How to fix Findbugs security warning for 'Potential Path Traversal (File Read)'
<p>I'm getting above warning with 'Method java.io.File reads a file whose location is specified by user input' message after running findbugs in the below code snippet.</p>

<pre><code>public void removeFile(String warfileName){
    File warFile = new File(homePath + "/samples/" + warFileName + ".war");
.....
}
</code></pre>

<p>What would be the best way of fixing this security isssue? </p>
