Using <hz:client> config element

[anucekay]

Here is my use case:

I have a hazel cluster that is spawn and running.

I want to have the client side configuration for this cluster.

<hz:client id="myHazelcast" group-name="${hazelcast.group}" group-
password="mypassword" >
<hz:member>${hazelcast.vip}</hz:member>
</hz:client>

within the java code, i want to get this client instance and create
maps/add entries etc.


hcmap =
Hazelcast.getHazelcastInstanceByName("myHazelcast").getMap(name);

Does not seem to work. I get NPE
Hazelcast.getHazelcastInstanceByName("myHazelcast");

My question is what is the best way to get at the hazelcast instance
that was created by the hz:client spring
configration.

Thanks
Anu

'Hazelcast.getHazelcastInstanceByName' returns actual Hazelcast instances not clients (although they implement the same interface; HazelcastInstance). The best way to get a Hazelcast instance (or client) that was created with Spring is to make Spring inject that bean into place we need. (That is Spring built for, isn't it?)

My old code which used the hazelcast intance would look it up from the
Hazelcast class and i expected the same code to work when
i moved to using the client. Was able to work around it.

When i was using the actual hazelcast instances, i was able to
redirect the logs to our specific log files by specifying
hazelcast.logging.type as shown below and then specifying
the appropriate logger for com.hazelcast in logback.xml

I wanted to redirect the logs from the client, i tried the
same but does not seem to work. Any pointers?

<hz:hazelcast id="MyInstance">
<hz:config>
<hz:instance-name>MyInstance</hz:instance-name>
<hz:properties>
<hz:property name="hazelcast.logging.type">slf4j</
hz:property>
</hz:properties>
<hz:network port="5702" port-auto-increment="true">
......
</hz:network>

You should set 'hazelcast.logging.type' as system property. (This works for both Hazelcast server and client.)

-Dhazelcast.logging.type=slf4j
