Spring 3 - Petclinic - ${owner.new} invalid expression in Tomcat 7

Question

I have deployed the petclinic code from the SPring 3 svn samples repository in Tomcat7 and I get the following exception:

Internal error

Root cause is: /WEB-INF/jsp/owners/form.jsp(4,1) "${owner.new}" contains invalid expression(s): javax.el.ELException: [new] is not a valid Java identifier org.apache.jasper.JasperException: /WEB-INF/jsp/owners/form.jsp(4,1) "${owner.new}" contains invalid expression(s): javax.el.ELException: [new] is not a valid Java identifier

This expression resolves perfectly well in SpringSOurce tc Server Developer Edition 2.0.

Any ideas why Tomcat 7.0.2 has a problem with it?

Answer 1

My guess is that the EL parser in Tomcat 7 is just a bit more strict than that in tcServer (which is based on Tomcat 6).

I suggest filing a bug at http://jira.springsource.org to that effect, it's almost certainly something they'll want to fix.
