title: Cannot start application in WebSphere when jars in the ear file don't have versions in their filename
body: <p>I have to modify the ear file so that the jar files that it contains don't have any version number in their filename.</p>
  
  <p>For example commons-io.jar instead of commons-io-2.4.jar.</p>
  
  <p>For that I used the expression <code>&lt;fileNameMapping&gt;no-version&lt;/fileNameMapping&gt;</code> in the pom file.</p>
  
  <p>With the version in the filenames, the application starts in WebSphere without problems.</p>
  
  <p>Unfortunately, without the version I get the following error:</p>
