Question

Can I run a Grails war under Tomcat in a machine without JDK (Only JRE)?

I have a Grails app that works fine in grails run-war or in a separate tomcat server in the same computer.

When I deploy this .war on a server that has a JDK, I have no problem.

When I try to do this in a server that only has a JRE, the application won’t work.

specs:

grails app:

• grails 1.2.2.
• groovyWS,
• i18n templates

dev pc:

• win xp sp3
• 2gb ram
• athlon 64 x 2
• java: build 1.6.0_20-b02 ( JDK )
• tomcat: 6.0.24 ( test 1 )
• tomcat 5.5 ( test 2 )

server that do not work:

• so: windows server 2003
• app server: tomcat 2.2 as a service ,
• java: 1.6.0.18 , ( ONLY JRE )
• wsclient: groovyws-0.5.1.jar ( minimal ) ( and all depenedncies added by hand )

Answer 1

GroovyWS needs javac to create stubs dynamically, so it needs JDK.
