Error in initializing a class of IPC 3.0 application in WAS 6.4

Question

Hello,
     When i trying to run IPC 3.0 application in WAS 6.4. I am getting an error as
#1.5#005056A244130043000000020000126800042596C6349F2A#1167229407602#/System/Server/WebRequests#sap.com/ipc_cesar#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#Guest#2####d19eb52095b511dba9f9005056a24413#SAPEngine_Application_Thread[impl:3]_34##0#0#Warning#1#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#Plain###Processing an http request to servlet [jsp] finished with error.The error is: Util is not yet initialized. No valid handle available. Invoke Util.initialize() method first.#
It Looks like the UTIL Initilization is not happening..... as the error says.
Please let me know Why Util is not getting initialized. Will this be because of Application not deployed properly or some other settings should be done for the same.
I have made entries in init-config.xml also . I have given the Information for the same below,
This Util is Initialized in UtilInitializer.java, I.e
     public static final String PROPERTIES_FILE = "PropertiesFile";
     public void initialize(InitializationEnvironment env, Properties props) {
          Util.initialize(props.getProperty(PROPERTIES_FILE));
This UtilInitializer.java program is called in init-Config.xml, which should be called when starting the application.The content is,
<initializations>
     <initialization className="com.sapmarkets.isa.core.logging.LogConfigurator">
          <!--       <param name="type"         value="log4j" />
       <param name="version"      value="1.04" />
       <param name="config-file"  value="/WEB-INF/cfg/log-config.xml" />-->
          <!-- this entry enables the SAP Logging API -->
          <param name="type" value="sapmarkets"/>
          <param name="config-file" value="/WEB-INF/cfg/log-config.properties"/>
     </initialization>
    <initialization className="com.sapmarkets.isa.core.businessobject.management.MetaBOMConfigReader" >
        <param name="config-file" value="/WEB-INF/cfg/bom-config.xml" />
    </initialization>
    <initialization className="com.sapmarkets.isa.ipc.ui.jsp.container.ConfigContainer">
    </initialization>
<!-- [ES] added to initialize the ConfigHelper log -->
    <initialization className="com.dcx.cesar.ipc.c2.init.UtilInitializer" >
        <param name="PropertiesFile"
            value="./services/servlet_jsp/work/jspTemp/ipc_cesar/root/WEB-INF/classes/C2Interface.properties" />
    </initialization>
</initializations>
Please let me know why am i getting this error and what can be done for solving this.

From the error message, it sounds like you need to define the actionPerformed(ActionEvent) required of implementing ActionListener as exactly
public void actionPerformed(ActionEvent e) {
    // whatever
}and you tried to give it non-public access, either private, protected, or package-private (default) access. Once you change it back to being public, your code should compile again.
In general, if you override a method, you must give it the same or greater accessibility as it had in the parent class. A method that is public has the greatest accessibility, followed by one that is protected, then one that is package-private (default), and finally one that is private.
