Jar files on server

[silvi]

Hello all,

I have a report with parameters using customized class. Report is working fine in i-report and jasper server reporsitory plugin too. 

I have added my .jar file that contains the class in "Add resources" section of server. But when I am running its throwing me an error saying "Error evaluating expression $P{dateUtils}.getEndDate( $P{DateChoice}, $P{Time_Interval}, $P{InputDate})". In the parameter I have specified the class which is com.redhat.eng.JasperDateUtils.

<parameter name="dateUtils" class="com.redhat.eng.JasperDateUtils" isForPrompting="false">
        <defaultValueExpression><![CDATA[com.redhat.eng.JasperDateUtils.getInstance()]]></defaultValueExpression>
    </parameter>
    <parameter name="endDate" class="java.util.Date" isForPrompting="false">
        <defaultValueExpression><![CDATA[$P{dateUtils}.getEndDate( $P{DateChoice}, $P{Time_Interval}, $P{InputDate})]]></defaultValueExpression>
    </parameter>

I am wondering why is it not working in japser server. Most probably, it is not able to get the classpath.

 

Please help...

Please, can someone tell me, how can we specify the class path on server ???

I did lot of reading and surfing but have not found anything.
