Just a quick one today...

Liferay stopped releasing Liferay CE/DXP Wildfly bundles after 7.1, so I was recently asked to create a Liferay 7.2 DXP bundle for Wildfly 11.

So I followed the instructions posted here: https://help.liferay.com/hc/en-us/articles/360029123751-Installing-Liferay-DXP-on-Wildfly

Started the Wildfly bundle and it seemed to come up fine. Navigating to the site, though, showed things were not right. I had no pages, no content, etc, although I could log in and interface elements were all seemingly working.

When I checked the logs, though, I found a slew of the following:

Well, a quick google showed that there was nothing on this, so I was left to solve it on my own. I got it working and wanted to post the details here in case you too run into this issue.

So first thing I did was to find the CC/PP dependency. I downloaded it from https://mvnrepository.com/artifact/javax.ccpp/ccpp/1.0 because I kind of trust mvnrepository.

I copied the jar to the $LIFERAY_HOME/wildfly-11.0.0.Final/modules/com/liferay/portal/main directory, then I added a line to the $LIFERAY_HOME/wildfly-11.0.0.Final/modules/com/liferay/portal/main/module.xml file to reference the new jar.

My updated module.xml file is:

<?xml version="1.0"?>

<module name="com.liferay.portal" xmlns="urn:jboss:module:1.0">
	<resources>
		<resource-root path="com.liferay.petra.concurrent.jar" />
		<resource-root path="com.liferay.petra.executor.jar" />
		<resource-root path="com.liferay.petra.function.jar" />
		<resource-root path="com.liferay.petra.io.jar" />
		<resource-root path="com.liferay.petra.lang.jar" />
		<resource-root path="com.liferay.petra.memory.jar" />
		<resource-root path="com.liferay.petra.nio.jar" />
		<resource-root path="com.liferay.petra.process.jar" />
		<resource-root path="com.liferay.petra.reflect.jar" />
		<resource-root path="com.liferay.petra.string.jar" />
		<resource-root path="com.liferay.registry.api.jar" />
		<resource-root path="hsql.jar" />
		<resource-root path="ccpp-1.0.jar" />

		<resource-root path="portal-kernel.jar" />
		<resource-root path="portlet.jar" />
		<resource-root path="postgresql.jar" />
	</resources>
	<dependencies>
		<module name="ibm.jdk" />
		<module name="javax.api" />
		<module name="javax.mail.api" />
		<module name="javax.servlet.api" />
		<module name="javax.servlet.jsp.api" />
		<module name="javax.transaction.api" />
	</dependencies>
</module>

After making these changes and restarting Wildfly, everything seemed to work.

Are there better ways to solve this problem? Perhaps. If you have a solution that works better than mine, please share in the comments below!
