EAR exported from One Websphere instance to another failed to start
<p>I have exported an EAR file from one IBM websphere environment (7.0) and installed in another environment. Though EAR file deploys without errors, it still fails to start.</p>

<p>Error message in admin client;</p>

<blockquote>
  <p>Application <code>MyApplication</code> did not start successfully on all of the servers in cluster <code>CLUSTER001</code>. Check log for details.</p>
</blockquote>

<p>Below is the log;</p>

<pre><code>WSVR0190I: Starting composition unit WebSphere:cuname=MyApplication in BLA WebSphere:blaname=MyApplication.
WSVR0200I: Starting application: MyApplication
WSVR0204I: Application: MyApplication  Application build level: Unknown
