Re: [jboss-as7-dev] Configuration of expression and system-properties (ejb3 subsystem)

I actually do not see any issue with 1) instead of doing ${my.prop:} just do ${my.prop} that will be empty or "" if my.prop is not set... -- tomaz ----- Original Message ----- From: "Jaikiran Pai" <jpai(a)redhat.com&gt; To: wfink(a)redhat.com Cc: jboss-as7-dev(a)lists.jboss.org Sent: Thursday, July 5, 2012 4:02:12 PM Subject: Re: [jboss-as7-dev] Configuration of expression and system-properties (ejb3 subsystem) There are 2 issues here: 1) The expression value validation isn't allowing empty values. So internally it results in: org.jboss.as.controller.OperationFailedException [ "JBAS014704: '' is an invalid value for parameter default-distinct-name. Values must have a minimum length of 1 characters" ] 2) This real exception isn't reported during server startup and I don't know the reason why. Please create separate JIRAs for this. I believe a fix for #1 would involve overriding the String type attribute validator with an custom validator which allows empty strings (since for default-distinct-name a empty string is a valid value). -Jaikiran On Thursday 05 July 2012 11:46 AM, Wolf-Dieter Fink wrote: > No, > If I configure the EJB subsystem with a correct distinct-default > everything works (see initial mail, "If I set property to XX...") > > My intention was to set the default-distinct name with an expression > and use the default "", > so it it possible to use the same profile for different server-groups > and configure the distinct name with a property. > > This works as long as I have a default different from "" or overwrite > with a property different from "". > But if I don't want the distinct name and set "", no difference > whether default or property, a execution with "no distinct name" will > not work. > > I've looked into the source and play around with expressions and > properties and it looks like that ${XY:} will set "" as I want and a > property with value="" works either. > So I don't understand at the moment why this don't work for distinct > name !? > > - Wolf > > On 07/05/2012 07:34 AM, Jaikiran Pai wrote: >> Sorry, I don't completely understand the issue.
