Birt Webviewer Deploy error in tomcat linked with apache

Shankar Balachandran

<p>Dear All,</p>
<p>I am trying to use BIRT webviewer along with another ERP application called Openbravo deployed in tomcat. In the production server, we have configured apache too. When I am trying to deploy webviewer in webapps, I am getting the following error,</p>
<p> </p>
<div>Nov 18, 2015 7:15:00 AM org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc</div>
<div>SEVERE: The web application [/BIRT] registered the JDBC driver [org.apache.derby.jdbc.AutoloadedDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.</div>
<div>Nov 18, 2015 7:15:00 AM org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc</div>
<div>SEVERE: The web application [/BIRT] registered the JDBC driver [org.postgresql.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.</div>
<div>Nov 18, 2015 7:15:01 AM org.apache.catalina.startup.HostConfig deployDirectory</div>
<div> </div>
<div>Can you please suggest any reason why this might occur? In my dev environment, it deploys fine. Thanks in advance for your help.</div>

<p>It might be problem occurred in deployment because your app internally have JDBC Driver and in BIRT  also you have registered the JDBC driver but both will have different references thats why both will generating conflict and tomcat will going prevent memory leak caused by use same driver by differen reference.</p>
<p> </p>
<p>So when you are using JDBC driver in BIRT report refer the same one that you are using in your App and try if same thing is happen or some change will occur.</p>
