Simple expression replaceAll causes an error when the input string containing a "." (dot)

[catshout <ge...@web.de>]

Dear all,

I'm gonna to filter out the value of "clientId" from a string like

{"timestamp":1442843609,"status":200,"request":{"mbean":"org.apache.activemq:brokerName=amq-broker,type=Broker","attribute":"DurableTopicSubscribers","type":"read"},"value":[{"objectName":"org.apache.activemq:brokerName=amq-broker,clientId=SIB0001,consumerId=Durable(SIB0001_SIB0001.article),destinationName=article,destinationType=Topic,endpoint=Consumer,type=Broker"},{"objectName":"org.apache.activemq:brokerName=amq-broker,clientId=SIB0001,consumerId=Durable(SIB0001_SIB0001.pdf),destinationName=pdf,destinationType=Topic,endpoint=Consumer,type=Broker"}]}

I've created an expression like this



It causes an error

org.apache.camel.language.bean.RuntimeBeanExpressionException: Failed to
invoke method: *", "$1") on null due to:
org.apache.camel.component.bean.MethodNotFoundException: Method with name:
*", "$1") not found on bean:
org.apache.activemq:brokerName=amq-broker,clientId=SIB0001,consumerId=Durable(SIB0001_SIB0001.pdf),destinationName=pdf,destinationType=Topic,endpoint=Consumer,type=Broker
of type: java.lang.String. Exchange[Message:
org.apache.activemq:brokerName=amq-broker,clientId=SIB0001,consumerId=Durable(SIB0001_SIB0001.pdf),destinationName=pdf,destinationType=Topic,endpoint=Consumer,type=Broker]

Does anyone have a hint how to use a "." (dot) in a Camel Simple regex
without causing such an error?

Many thanks in advance
- Gerald
