Exception while Deploying war file

[sameer]

i am getting an exception saying "<param-name> is not allowed inside <init-param>" of web.xml file;when i deployed war file into ../server/default/deploy directory.But my application needs to access those parameters for start-up, please suggest if there is any alternative for the same.

check the ordering in the dtd.

we insist (per spec) on strict element ordering. This will ensure maximum portabilityof your app.

Exception thrown for the portion of web.xml is


<servlet-name>
InitiateWFTrackerServlet
</servlet-name>
<servlet-class>
kdk_SystemUtils.workflowtracker.InitiateWFTrackerServlet
</servlet-class>

<init-param>
<param-name>kdk_ResourceBundleClass</param-name>
<param-value>kdk_Library.kdk_ResourceBundleClass</param-value>
<param-name>kdk_WFTrackerTimerClass</param-name>
<param-value>kdk_SystemUtils.workflowtracker.kdk_WFTrackerTimerClass</param-value>
</init-param>
<load-on-startup>1</load-on-startup>


same xml file is read without any error by tomcat server

[chgrimm]

if you look at the dtd you will see, that <init-param> is a repeatable element while <param-name> in <init-param> may only occur once. That's why the parser throws an error for your xml.

change it to:

<init-param>
<param-name>kdk_ResourceBundleClass</param-name>
<param-value>kdk_Library.kdk_ResourceBundleClass</param-value>
</init-param>
<init-param>
<param-name>kdk_WFTrackerTimerClass</param-name>
<param-value>kdk_SystemUtils.workflowtracker.kdk_WFTrackerTimerClass</param-value>
</init-param>


PS:
dtd's are awfull to read but it's worth to have a look in you run in this kind of problems
you find the dtd at http://java.sun.com/dtd/web-app_2_3.dtd

thank you
i downloaded the dtd it allows only one pair per init-param
