I tried your scenario and got the same output as yours. Then looked deep into it as this was a basic functionality and as I thought I've done something similar before.
The issue here is in the type of the property. For some strange reason INTEGER
does not work here. You need to have DOUBLE
or STRING
. Even if you have string, it will correctly cast it when you do a comparison as in here. The following worked for me.
<inSequence>
<log level="full"/>
<property xmlns:m0="http://tempuri.org/"
name="CParam"
expression="//m0:SumSerViseResponse/m0:SumSerViseResult"
scope="default"
type="DOUBLE"/>
<log level="custom">
<property name="CParam" expression="$ctx:CParam"/>
</log>
<property name="propertyA" value="4.0" scope="default" type="DOUBLE"/>
<log level="custom">
<property xmlns:ns="http://org.apache.synapse/xsd"
name="propertyA"
expression="get-property('propertyA')"/>
</log>
<property name="propertyCompare"
expression="$ctx:CParam > get-property('propertyA')"
scope="default"
type="BOOLEAN"/>
<log level="custom">
<property name="propertyCompare" expression="get-property('propertyCompare')"/>
</log>
<filter xpath="$ctx:CParam > get-property('propertyA')">
<then>
<send>
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
</endpoint>
</send>
</then>
<else>
<drop/>
</else>
</filter>
</inSequence>
