By default, after installation Openfire Hazelcast plugin has
<ssl enabled="false"/>
in its config file. My attempt to enable it broke clustering and Openfire log said that
java.lang.IllegalStateException: SSL/TLS requires Hazelcast Enterprise Edition
Is it correct, so there is no way to make Hazelcast plugins using SSL for communications between Openfire nodes?
Assuming that the Hazelcast Enterprise API is an extension of the Hazelcast API, it might be as simple as recompiling the Openfire Hazelcast plugin with a different Hazelcast dependency.
I did a quick test. The plugin compiles just fine after you swap the dependency on Hazelcast with a dependency on the 'enterprise' variant, like this (your version number might vary):
<dependencies>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-enterprise</artifactId>
<version>3.10.6</version>
</dependency>
</dependencies>
<repositories>
<repository>
<id>hazelcast</id>
<url>https://dl.bintray.com/hazelcast/release/</url>
</repository>
</repositories>
Most of the Hazelcast configuration can be done in the XML file that's already accessible as a stand-alone file in Openfire. There's a good chance that you don't need any code modifications to get things configured in the way you want.
I am not sure if this has been attempted before but you can try the following:
plugins folder of Openfire. I am not certain about the internals of Openfire but if there exists a maven configuration to import Hazelcast then modify that to load Hazelcast enterprise. Or if nothing else works then try renaming the Hazelcast jar from hazelcast-enterprise.jar to hazelcast.jar.conf/hazelcast-local-config.xml to configure license key and security details SSL.Here is a link to Openfire doc for Hazelcast plugin: https://www.igniterealtime.org/projects/openfire/plugins/2.4.0/hazelcast/readme.html#config
Please do update here if this works.
