Hazelcast.xml:

`

        <multicast enabled="false" />
        <tcp-ip enabled="true">

`

Hazelcast-client.xml:

<?xml version="1.0" encoding="UTF-8"?> <hazelcast-client xsi:schemaLocation="http://www.hazelcast.com/schema/client-config hazelcast-client-config-3.6.xsd" xmlns="http://www.hazelcast.com/schema/client-config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <network> <cluster-members> <address>127.0.0.1:5701</address> </cluster-members> </network> <serialization> <serializers> <global-serializer override-java-serialization="true">info.jerrinot.subzero.Serializer</global-serializer> </serializers> </serialization> </hazelcast-client>

Its work fine if configure pro-grammatically, but fail with xml configuration . Hazelcast node is starting properly with this xml configuration, client is throwing error , please suggest ?

Thanks

hi @mukul4u2005,

what is your Hazelcast version? I can see you are using 3.6 in your XSD. Your XML references this schema: <?xml version="1.0" encoding="UTF-8"?> <hazelcast-client xsi:schemaLocation="http://www.hazelcast.com/schema/client-config hazelcast-client-config-3.6.xsd"

I guess this schema does not have the override-java-serialization attribute. Can you try it with a new schema?
