FILENOTFOUNDEXCEPTION while reading property files in Tomcat 6------Help me

Question

Hi All
I am planning to migrate my web application from iplanet 4.1 to tomcat 6. In this process I need to read the properties files initially.
for eg: i got the property files in a iPlanet:
Config directory---
abc.properties.---
abc.log--
In tomcat I configured them in web.xml saying that.
<servlet>
<servlet-name>ABC</servlet-name>
<servlet-class>com.ijk.abc</servlet-class>
<init-param>
<param-name>Loan</param-name>
<param-value>/WEB-INF/config</param-value>
</init-param>
<init-param>
<param-name>loan.props</param-name>
<param-value>/WEB-INF/config/abc.props</param-value>
</init-param>
<init-param>
<param-name>loan.log</param-name>
<param-value>/WEB-INF/config/abc.log</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ABC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
I need to read initially all the property files and then proceed.
While configuring in this way, it am getting error saying that
abc.props or abc.log..............(FILE NOT FOUND EXCEPTION)
Can anyone suggest me how to configure them.
Thanks in Advance.

Thanks for your response, Actually we dont have the source code for that because it is very old code, but i m using decompiler in which i can get some informtaion.
OS used for iPlanet is Unix but now I need to deploy this application in tomcat in windows server 2003.
Servlet clss:
SERVLET CLASS:
Class com.ijk.abc implements extends HttpServlet  implements PropertyKeys
private IClickManager m_im;
public void init(ServletConfig paramServletConfig)
    throws ServletException

      super.init(paramServletConfig);
      Utils.info("ServerInfo: " + getServletContext().getServerInfo());
      PGroup localPGroup = this.m_im.claimPG();
      Utils.trace("Got " + localProcessorGroup + " for initialization");
      this.m_im.gatherProperties(localProcessorGroup);-----------this is where it is calling the property files.
      this.m_im.freePG(localPGroup);
      Utils.trace("Released " + localPGroup + " for new Properties");
      localPGroup = this.m_im.claimPG();
      Utils.trace("Got " + localPGroup + " for new Properties");
      try
        ConHandler localDBHandler = (ConHandler)localPGroup.getDBHandler("config.dbhandler");
        this.m_im.setNumPGs(localDBHandler.getNumPGroups());
      catch (Exception localException1) {
        Utils.info("NON FATAL ERROR: failed to set number of PGs", localException1);
      try
        Session.createAndStartSessionTask(localPGroup);

=================================================================
the above is the servlet class and the method which is using to read the property files from root directory in Unix.
ie../opt/mywebapp/loan/abc.props,abc.log
loan is the directory in which two property files are placed.
i just want to where to place property files in tomcat so that its going to read the property files.
Right now, i placing it in the WEBAPPS/MYWEBAPPLICATION/WEB-INF/LOAN/abc.props,abc.logs.
Its giving me errors such as FILENOTFOUNDEXCEPTION or cannot read the property files.
The main problem is ...I donot have the complete source code. while decompiling i m not able view complete source code.
Please help me regarding this.........
Thanks in advance.
