Issue/Introduction

Symptoms:

Unable to view Smarts Notifications in Watch4Net|M&R. Following error seen in Tomcat cas log:

The Spring ContextLoaderListener we wrap threw on contextInitialized.
But for our having caught this error, the web application context would not have initialized.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ticketRegistry': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/deployerConfigContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: CasPersistence] Unable to build EntityManagerFactory
 

 

Environment

Watch4Net/M&R - 7.X

Cause

In /APG_HOME/Web-Servers/Tomcat/Default/webapps/cas/WEB-INF/deployerConfigContext.xml IP/FQDN of Master DB in JDBC URL set is incorrect.

Resolution

To resolve the issue, modify the deployerConfigContext.xml on the Frontend host as mentioned below:

• Path to file:
   /APG_HOME/Web-Servers/Tomcat/Default/webapps/cas/WEB-INF/deployerConfigContext.xml
• Make sure the file doesn't contain localhost for the following section:
  
   <!-- START EMC W4n Change -->
  <util:properties location =
        "#{'file:///'+systemProperties['catalina.home'].trim()+'/../../../Custom/WebApps-Resources/Default/property/emc-smarts.properties'}"
        id="myProps"/>

    <bean id="objMapper" class="com.fasterxml.jackson.databind.ObjectMapper" />

    <bean id="dbConfigJson" factory-bean="objMapper" factory-method="readTree">
      <constructor-arg value={&quot;url&quot;:&quot;jdbc:mysql://IP|FQDN:53306/masterautoReconnect=true&amp;connectTimeout=20000&amp;maxReconnects=2&amp;u

    </bean>

    <bean id="casDatastore" class="com.watch4net.apg.gui.datasource.jdbc.JDBCFactory" factory-method="createDatasource">
      <constructor-arg ref="dbConfigJson" />
    </bean>

• It should be the IP/FQDN of the primary backend host.
• After making the change and saving the file, restart tomcat service.
  • /APG_HOME/bin/manage-modules.sh service restart tomcat <instance name>
• Once the tomcat service comes back up, Refresh the report and you should be able to view the notifications.
