While trying to create a poorman's auditing system with Liferay 7 I ran into some challenges. So to prevent you make the same mistakes you can learn from my mistakes.

First you need to create a portal-log4j-ext.xml that will be used to override portal-log4j.xml Mine looks like this but yours might be totally different:

<?xml version="1.0"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

{
    "availableLanguageIds": [
        "en_US"
    ],
    "defaultLanguageId": "en_US",
    "fields": [
        {
            "label": {
                "en_US": "Url"
            },

A quick summary of https://portal.liferay.dev/docs/7-0/tutorials/-/knowledge_base/t/using-resources-and-permissions

Important

To see the security settings for the service you MUST have a portlet reference. If you don't have a portlet just yet try to refer to an existing one like com_liferay_blogs_web_portlet_BlogsPortlet

Define portlet.properties

Create a file portlet.properties in .../[project]-service/src/main/resources/ Add resource.actions.configs=META-INF/resource-actions/default.xml in the file.

Declare resources and their permissions in default.xml

Howto install apache felix web console on liferay dxp 7.2

First locate the url for the webconsole jar-file at https://felix.apache.org/downloads.cgi

In this example I use the following:

Now, head over to your gogo shell (web|telnet|blade sh)
