For security reasons, you must enable User Code Namespaces using static configuration. You can do this programmatically, or using the Hazelcast configuration file.
| If using dynamic persistence, this must be enabled in the Hazelcast configuration file. For further information persisting changes, see the Dynamic Configuration Overview topic under the Configure and Manage Clusters section. |
Enable Programmatically
To enable User Code Namespaces programmatically, create a Member.java file, add the following, then save the file to your configuration folder:
package com.hazelcast.namespace.staticconfig.classconfig;
import com.hazelcast.config.Config;
import com.hazelcast.config.UserCodeNamespaceConfig;
import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
public class Member {
public static void main(String[] args) {
Config config = new Config();
config.getNamespacesConfig().setEnabled(true);
HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);
}
}Enable in Configuration File
To enable User Code Namespaces using the hazelcast configuration file, complete the following steps:
Complete the Configuration
You can continue your configuration as follows:
-
In the hazelcast configuration file, as described in the Static Configuration section
-
Using static programmatic configuration, as described in the Programmatic Configuration topic
-
Using dynamic configuration, as described in the Dynamic Configuration API section
