mc.setProperty('table',table);]]></script>
<property expression="get-property('table')" name="uri.var.table" scope="default" type="STRING"/>
<call>
<endpoint>
<http method="get" uri-template="http://ITMTNF3RRJSJ:8290/services/studenttest/readtable?table={uri.var.table}">
<suspendOnFailure>
<initialDuration>-1</initialDuration>
<progressionFactor>-1</progressionFactor>
<maximumDuration>0</maximumDuration>
</suspendOnFailure>
<markForSuspension>
<retriesBeforeSuspension>0</retriesBeforeSuspension>
</markForSuspension>
</http>
</endpoint>
</call>
<enrich>
<source clone="true" type="inline">
{"nomtable":""
}
</source>
<target action="child" xpath="json-eval($.tables)"/>
</enrich>
<enrich>
<source clone="true" property="uri.var.table" type="property"/>
<target xpath="json-eval($.tables.nomtable)"/>
</enrich>
<iterate expression="//tables">
<target>
<sequence>
<property expression="json-eval($.tables.nomtable)" name="nomtable" scope="default" type="STRING"/>
<log level="custom">
<property expression="get-property('nomtable')" name="m"/>
</log>
<script language="js"><![CDATA[var str = mc.getProperty('nomtable');
var annee= str.substr(1, 4);
annee==annee.toString();
var mois=str.substr(5, 2);
var jour=str.substr(7, 2);
mc.setProperty('annee',annee);
mc.setProperty('mois',mois);
