Grails on GlassFish v3 - Embedded or Stand-alone


Grails 1.0.3 was released a few weeks ago. This blog uses the instructions originally posted here and shows how to deploy a simple Grails application on GlassFish.

  1. Download Grails 1.0.3 and unzip.
  2. Download the latest *-overlay.zip from here and unzip on your Grails installation as shown:

    ~/tools/grails-1.0.3 >unzip ~/Downloads/grails-gfv3-1.1-overlay.zip
    Archive:  /Users/arungupta/Downloads/grails-gfv3-1.1-overlay.zip
       creating: lib/glassfish-v3/
      inflating: lib/glassfish-v3/gf-embedded-api-1.0-alpha-4.jar 
      inflating: lib/glassfish-v3/web-all-10.0-build-20080430.jar 
      inflating: lib/grails-gfv3-1.1.jar 
      inflating: scripts/RunAppGf.groovy
  3. Create a sample app as explained in Getting Started With Grails on GlassFish.
  4. Run the app using embedded GlassFish as:

    ~/tools/grails-1.0.3/samples/helloworld >grails run-app-gf

More details about GlassFish embedding in Grails are available here.

This application can also be deployed on stand-alone GlassFish v3 Technology Preview 2 as explained here. This blog explains how to configure JNDI resources for a Grails application and I plan to explore that in upcoming days.

Once the Servlet engine in Grails is made configurable then GlassFish can be used as the target deployment platform from "run-app" script.

NetBeans 6.5 M1 provide extensive support on Grails application development - details are available here.

Hi Arun,

Thanks for the post.

I ran into a couple of problems when I tried this. I needed to do the install into tools/grails-1.0.3/grails instead of the tools/grails-1.0.3 directory you mentioned.

After I did that my application ran but there were two issues:

1,I got the following SEVERE messages in the output:

31-Jul-2008 11:25:08 com.sun.enterprise.deployment.io.DeploymentDescriptorFile read
SEVERE: enterprise.deployment.backend.saxParserError
31-Jul-2008 11:25:09 org.apache.catalina.loader.WebappLoader setClassPath
INFO: Unknown loader org.glassfish.grails.MaskingClassLoader@1e965e9 class org.glassfish.grails.MaskingClassLoader
31-Jul-2008 11:25:09 com.sun.enterprise.web.WebModuleContextConfig authenticatorConfig
SEVERE: webModuleContextConfig.missingRealm
31-Jul-2008 11:25:10 org.apache.catalina.core.StandardContext start
SEVERE: PWC1315: Error reading listeners from TLD
javax.servlet.ServletException: PWC3037: Exception processing TLD at resource path /WEB-INF/tld/spring.tld in context /HelloWorld

2, I could access the application, but none of the styling was available.

Any ideas why this might be the case? Anyone else hit these problems?

Thanks,
ngu

New Grails User,

The install can be done in any directory as long GRAILS_HOME is set correctly.

"SEVERE: webModuleContextConfig.missingRealm" is filed as a bug at:
https://glassfish.dev.java.net/issues/show_bug.cgi?id=4917

I did not see any other SEVERE messages as is evident from the console dump in the entry.

The screen dump shows the Grails image and font rendered properly. If you still see an issue, I recommend file a bug at:

https://glassfish.dev.java.net/servlets/ProjectIssues

Hi Arun,

Thanks for the reply. The problem might not have been clear from the stack trace, but it looks like there is an issue with the spring.tld. The relevant details are included below.

It's a newproject, so I can't understand why I'm getting this problem.

I did find a reference to the exception code here, http://fisheye5.atlassian.com/browse/glassfish/appserv-webtier/src/java/org/apache/catalina/startup/TldConfig.java but I'm still none the wiser.

It might just be a network problem as I'm getting a Connection Refused message in the stack trace.

Anyone have any ideas?

Best wishes,
ngu

Just in case anybody saw this problem I was hitting. I found out what was happening.

Looks like the problem I was hitting was to do with our firewall. I've set up the grails proxy via grails set-proxy and everything is working as expected.

Thanks again for the great post. Keep up the good work.

Hi all,

I encountered a HTTP Status 503 error when I tried to deploy my Grails app on Glassfish.

Can somebody help?

Posted by Andrei on October 14, 2008 at 05:22 AM PDT #

Andrei,

Can you give more details about your configuration ? Did you try deploying the app described above or something else ?

Posted by Arun Gupta on October 14, 2008 at 02:16 PM PDT #

My bad.. I know why I got the 503 error message.

The app took a while to startup. However, does it really take about 7-10 minutes to get the application to start up or it would depend on the server environment?

Posted by Andrei on October 14, 2008 at 04:54 PM PDT #

Andrei,

7-10 minutes is certainly way too much by any standards. Can you file a bug at:

https://glassfish.dev.java.net/issues/enter_bug.cgi?issue_type=DEFECT

Choose "deployment" as sub-component.
