title: Load ResourceBundle from classpath
body: <p>I have two jar files. One of the jars needs to read language pack from another jar. Here is basic structure of both jars</p>
  <pre>
  jar1    
     |--com.example.BundleLoader 
  
  jar2
     |--strings
           |--language.properties
           |--language_fr.properties
  </pre>
  <p>Language pack is on the classpath. In order to read language packs by the BundleLoader I am trying to use ResourseBundle in conjunction with ClassLoader.
  This is how I am attempting to do that</p>
  <pre><code>private ResourceBundle englishStrings = null;
  private ResourceBundle frenchStrings = null;
  
  System.out.println(&quot;About to load url from classpath for properties file &quot; + bundleLocation);
  URL url = ClassLoader.getSystemResource(bundleLocation);
  bundleLocation = url.toString();
  System.out.println(&quot;Ok loaded it&quot;);
  System.out.println(&quot;url is &quot; + (url == null ? &quot;not available&quot; : url.toString())); // Got the folder location
  
  try {
      URL[] urls = { new URL(bundleLocation) }; // created array of ULRs to be loaded by URLClassLoader
      englishStrings = ResourceBundle.getBundle(&quot;validationStrings&quot;, Locale.getDefault(),
              new URLClassLoader(urls)); // Exception here
      frenchStrings = ResourceBundle.getBundle(&quot;validationStrings&quot;, Locale.FRENCH, 
              new URLClassLoader(urls));
  } catch (MalformedURLException e1) {
      e1.printStackTrace();
  }
  &lt;--End of Snippet--&gt;

  <p>Basically I can't find bundles even though property files are in the folder. Have anyone ran into this? I assume that someone dealt with this before.</p>
  <p>Thank you.</p>
