Error: No class definition found
<p>I have added jars with the below procedure:</p>

<ol>
<li>Right-click on the project in Eclipse and select “Build Path -> Add Libraries…”.</li>
<li>Select User Library from the list and click Next.</li>
<li>Click the “User Libraries…” button.</li>
<li>Click “New…” in the User Libraries dialog.</li>
<li>Give the user library a name and select the System library checkbox and click OK.</li>
<li>Highlight the newly added user library in the list and click the “Add JARs…” button and add the desired jar files.</li>
<li>Click OK on the User Libraries dialog.</li>
<li>Make sure the new user library is checked in the Add Library dialog.</li>
</ol>

<p>After running the application it is saying that "<code>No class definition found</code>" and "<code>could not find the class</code>" errors.</p>
