[opencms-dev] Feedback for deployment on GlassFish

[Jan Michael Greiner]

Dear all,

Feedback for deployment on GlassFish.
Glassfish 4.1
OpenCms 9.5.2 (9.5.0???)

The following is not pure science (not repeatedly tested), just feedback after some trying.

1.) It works :-)

2.) Not 100% sure about this one: It is not possible, to assign more than one virtual server to the OpenCms Application.

See the attached snippet from Glassfish server.log (server.log-jax-ws.zip). I have the impression, that maybe the following is caused by assigning more than one virtual server:

org.apache.catalina.LifecycleException: Manager has not yet been started

org.apache.catalina.LifecycleException: java.lang.IllegalStateException: Servlet with name Dynamic JAXWS Servlet does not have any servlet-class or jsp-file configured

Exception while loading the app

Shutting down OpenCms, version 9.5.0 in web application "opencms"

Shutdown completed, total uptime was 00:00:38.


Could be related to this:
http://lists.opencms.org/pipermail/opencms-dev/2013q1/037818.html


It would help to register OpenCms to more than one Virtual Server, to at distinguish between
a) a virtual server that listens with SSL only for the Workspace
b) a virtual server for the actual Website


3.) If the Webapp is somehow redeployed, without a complete restart of Glassfish (after some config changes or so), it does not work any more.
>From my memory: Web browser window stayed white.

Don't know, if the attached log snippet from Glassfish server.log (server.log-jdbc-forcibly-unregisterd.zip) is related to this.

I just tried to reproduce it (clicked "Reload" in the applications list), but now I don't get the 'jdbc forcibly unregistered' thing. Now I get:
org.opencms.main.CmsInitException: Critical error during OpenCms initialization: Unable to initialize the user driver

See attached log snippets from Glassfish server.log and opencms.log (not-able-to-reproduce_no-error-cause.zip).

A complete restart of Glassfish always fixed this problem...




I have no apache installed. I like java for security reasons, because there are no buffer overflows and so.
(I hope GlassFish and OpenCms are not affected by
http://www.heise.de/security/meldung/Zero-Day-Alarm-fuer-viele-Server-mit-Java-2913605.html )

To fix 2.) I am planning to

- Create a virtual server on an internal port (for example 127.0.0.1:8081) for the opencms webapp alone, that listens for all required host names.
- Put a proxy servlet on all virtual servers that I want to serve content from OpenCms. These proxy servlets forward to 127.0.0.1:8081. If necessary they forge the HttpServletRequest as required.



Best Regards

Michael
