hi there,

I want to implement SSL in grails. I cannot find the file /conf/server.xml in grails folder structure. Has any dev faced similar problem?

Much appreciated.

Marc I think you are getting lots of support questions as a google search for Grails + Tomcat puts your site as the #1 result

I believe he is calling run-app on his dev machine, not on the server.

Guys… this isn’t a support forum! Get on the Grails user list, it’s the best place. Go to http://grails.org/Mailing+lists here and sub.

Quick answers though… Tomcat zombieing at startup… change your java options (usually the env var JAVA_OPTS) to something like “-server -Xmx512M”, you are likely seeing garbage collection problems. This will increase performance hugely for you during development also, so put export JAVA_OPTS=”-server -Xmx512M” or similar in your .bash_history or wherever you like so it is run before you do grails run-app.

Tomcat needs libs? Nope. Grails apps contain all their dependencies. The issue you are seeing is a classpath/dynamic metaclass issue that I think is known / fixed. Please ask on the mailing list.

Do Tomcat needs some library installed previously? After installing 0.5.8 and following a example in http://anchorvale.wordpress.com/2007/08/03/grails-quickstart/ I only get this error after inserting 2 records:

I am not having any success deploying the war on a Mac 10.49. Tomcat just hangs on startup. After a while I get an WARNING message about Java Servlet 2.3 (nothing specific). Any ideas?

… ok, the problem was the JVM Version, now tomcat the running status is TRUE

but! now are the problems calling a page “HTTP Status 404 – /racetrack-0.1/WEB-INF/grails-app/views/user/login.jsp” Why TomCat try to access to an JSP instead of GSP? …grrr

I have problems by deploying the application in TomCat

Using: TomCat 6 — grovvy 1.0 — grails 0.5

Application:
the tutorial form “Getting Started with Grails” you can download the book and sources from: http://www.infoq.com/minibooks/grails;jsessionid=A90BD951D5B0532F2B6B2CB26510D3E8

when i start the application from command line by using “grails run-app” the application starts and i can open it in a browser

our production server is a tomcat, so i try to published the grails project within tomcat … “grails war” –> using tomcat manager “Select WAR file to upload” –> try to start the uploaded project and get an error “FAIL – Application at context path /racetrack-0.1 could not be started”

How to run a Application on TomCat? Can you halp me, please?
