Spring Gemfire New Comer <gfe:client-region> no declaration exception

[howardspring]

Just started to explore gemfire and need to use Spring Gemfire Integration.

I alwasys got a runtime error when use: <gfre:client-cache ...> bean declaration. Don't know the root cause. The related bean context definitation and the error msg is attached.

----------------------------------------------------------------------------------------------------------
Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefi nitionParsingException: Configuration problem: Failed to import bean definitions from relative location [client-worker-cache-context.xml]
Offending resource: class path resource [client-worker-app-context.xml]; nested exception is org.springframework.beans.factory.xml.XmlBeanDefin itionStoreException: Line 12 in XML document from class path resource [client-worker-cache-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException;... : The matching wildcard is strict, but no declaration can be found for element 'gfe:client-cache'. at org.springframework.beans.factory.parsing.FailFast ProblemReporter.error(FailFastProblemReporter.java :68)

----Below is the client cache in my cache-context.xml-----

.....
<gfe:client-cache pool-name="client"/>
<gfe:pool subscription-enabled="true" id="client">
<gfe:server host="localhost" port="40404"/>
</gfe:pool>


also I see a bean defination somewhere as:
<gfe:client-region id="dataRegion" cache-ref="data-cache" pool-name="data-pool" data-policy="NORMAL" />p
two questions: 1)where to find the doc regarding the bean shortcut attributes such as cache-ref xml sematics/options? The refrence guide I have doesnot talk about these options.
2) I don't see "data-cache" defined anywhere, how does this config work? in fact when I tried myself, I got error, data-cache is not specified.

Can anybody help? Very frustrated.

...The matching wildcard is strict, but no declaration can be found for element 'gfe:client-cache'. the context.xml below has a smiley icon which is : and p (how to disable smiley ?)
