There is a coherence cluster (with a cache by name mycache) that is runnig on ip address xxx.xxx.xxx.xxx (not localhost). I am trying to connect it and read from cache using java.
This is my Reader class:
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
public class Reader {
public static void main(String[] args) {
NamedCache cache = CacheFactory.getCache("mycache");
System.out.println("Value in cache is: " + cache.get("key1"));
}
}
I am using Intellij IDEA, in vm option for reader I added this line:
-Dtangosol.coherence.cacheconfig=mycache.xml
and this is mycache.xml file:
<?xml version='1.0'?>
<coherence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.oracle.com/coherence/coherence-operational-config"
xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-operational-config
coherence-operational-config.xsd"
xml-override="{tangosol.coherence.override /tangosol-coherence-override-{mode}.xml}">
<cluster-config>
<member-identity>
<cluster-name>RemoteCluster</cluster-name>
</member-identity>
<unicast-listener>
<well-known-addresses>
<socket-address id="1">
<address>192.168.104.160</address>
<port>8088</port>
</socket-address>
</well-known-addresses>
</unicast-listener>
</cluster-config>
</coherence>
when I run reader.main() I get this exception:
Problem : An ElementProcessor could not be located for the element [coherence]
Advice : The specified element is unknown to the NamespaceHandler implementation. Perhaps the xml element is foreign to the Xml Namespace?

it looks like the problem in the mycache.xml. Those elements used when you want to set up cluster member, while you want to connect a client.
Assuming that "mycache" schema exists on remote cluster try to change the mycache.xml with following:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config xmlns="http://schemas.tangosol.com/cache">
<caching-scheme-mapping>
<cache-mapping>
<cache-name>mycache</cache-name>
<scheme-name>extend-dist</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<remote-cache-scheme>
<scheme-name>extend-dist</scheme-name>
<service-name>ExtendTcpCacheService</service-name>
<initiator-config>
<tcp-initiator>
<remote-addresses>
<socket-address>
<address>192.168.104.160</address>
<port>8088</port>
</socket-address>
</remote-addresses>
</tcp-initiator>
<outgoing-message-handler>
<request-timeout>20s</request-timeout>
</outgoing-message-handler>
</initiator-config>
</remote-cache-scheme>
</caching-schemes>
</cache-config>
Note: if remote cluster uses POF serialization for mycache you'll have to add POF mapping and configuration -Dtangosol.pof.enabled=true
