Turning off Hazelcast in Payara Micro

Just wanted to turn off hazelcast in my Payara Micro instance.

I've tried putting the following in my postboot file, but that doesn't work:

set-hazelcast-configuration --enabled=false

A quick google search found reference [1].

Just adding --nocluster as a commandline parameter when running Payara Micro does the trick.

Setting session timeout in Glassfish

People complained that their sessions timed-out too quickly in Glassfish.

I checked and it is set to 30 minutes (default 1800 seconds), just a tad too little.

Increased it to 2 hours (7200 seconds).

Just went to Configurations - Web Container - Session Properties - Session Timeout.

It changes the domain.xml:

<session-properties timeout-in-seconds="7200"></session-properties>

Problem

Of course, this completely and utterly failed to work in my case.

It turns out I already had a session timeout specified in the web.xml.

<session-config>
  <session-timeout>
    30
  </session-timeout>
</session-config>

The session timeout in the web.xml is specified in minutes.

You can also specify it in the glassfish-web.xml file.¹

<session-config>
    <session-properties>
        <property name="timeoutSeconds" value="600"/>
        <property name="enableCookies" value="false"/>
    </session-properties>
</session-config>

Precedence

You do need to check which setting takes precedence in your application. It's not clear from the documentation.

Migrating between JEE versions

I had an issue where I wanted to port my current JEE 6 (Web profile) application (YPPO) to JEE 7 (Full profile).

This concerns a Netbeans project (built using Ant)

I thought I'd just write down which files needed changing.

nbproject/project.properties

-j2ee.platform=1.6-web
+j2ee.platform=1.7
