<?xml version="1.0" encoding="UTF-8"?>
<xml>
    <brand name = "BCREDIT">
         <client name="testws">
             <config_version>BCREDIT_1.0.0.2</config_version>
             <app_version>1.3.6</app_version>

6) make the following change in this web.xml:


C:\Tomcat5.5\webapps\ws\WEB-INF\web.xml:

<init-param>
            <param-name>configLocation</param-name>
            <!-- <param-value>/export/home/btec/.credit/configuration.xml</param-value> -->
            <param-value>C:/tomcat5.5/conf/configuration.xml</param-value>
</init-param>



* change C:\Tomcat5.5\conf\configuration.xml set to 1.3.6

<client name="testws">
             <config_version>BCREDIT_1.0.0.2</config_version>
             <app_version>1.3.6</app_version>
        </client>

* run 1.3.6 version of application as follows:

  javaws http://localhost:8080/ws/BCREDIT/testws/BrokerTec.jnlp

* Next, change C:\Tomcat5.5\conf\configuration.xml file to 1.3.5

<client name="testws">
             <config_version>BCREDIT_1.0.0.2</config_version>
             <app_version>1.3.5</app_version>
        </client>

 restart tomcat and ran 1.3.5

    javaws http://localhost:8080/ws/BCREDIT/testws/BrokerTec.jnlp

* Changed back to 1.3.6 restarted Tomcat no problem

* Changed back to 1.3.5 restarted tomcat no problem

* you may want to delete C:\Documents and Settings\anassiry.VOS\Application Data\Sun\Java\Deployment\cache after stopping tomcat and before restarting it

* Changed back to changed back to 1.3.6 reproduced the exception:
