I'm trying to install Liferay DXP (7.2.10.8-sp8) on a WebLogic
appserver (12.2.1.3), and I'm following the steps described in the
Liferay's official documentation (Installing Liferay DXP on WebLogic
12c R2). I've defined a deployment, linked to the proper DXP .war
file. When I start the deployment process, the installation process
gets started but it finally throws some warnings and errors. The first
warning displayed shows this message:
<Warning> <J2EE> <BEA-160140> Unresolved optional
package references (in META-INF/MANIFEST.MF): [Extension-Name:
javax.crypto, referenced from:
F:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\servers\AdminServer\tmp\_WL_user\liferay-dxp-7.2.10.8-sp8\wkozdz\war\WEB-INF\lib\_wl_cls_gen.jar].
Ensure that the referenced optional package has been deployed as a library.
An then, some other warnings and errors
(java.lang.NullPointerException) are displayed, related to user
defined listener 'com.liferay.portal.spring.context.PortalContextLoaderListener'.
I'd really appreciate if someone could clarify to me where the
problems could come from.
Thanks in advance.
