java.lang.ClassNotFoundException: org.joda.time.ReadablePartial
<p>I'm using Eclipse Luna with Jaspersoft Studio plugin 6.2.2 to developer reports for web application. No problem to run one basic blank report from Eclipse plugin, but when I load this jrxml from java class, I receive the message:</p>

<pre><code>Servlet.service() for servlet [default] in context with path [/insurance] threw exception [Filter execution threw an exception] with root cause
java.lang.ClassNotFoundException: org.joda.time.ReadablePartial
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1858)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1709)  
</code></pre>

<p>I'm using the code:</p>

<pre><code>JasperDesign jasperDesign = JRXmlLoader.load(fileName);
</code></pre>

<p>What's this error? </p>
