[Mav-user] webwork, maverick and 24x7
Hi, I have two webapps using Webwork, Maverick, Tomcat 4.1, Hibernate, JSP views (but switching to freemarker soon). These web applications have to be available 7 days a week, 24 hours a day but the problem is they need new features almoust every day. But I am kind of tired of deploying new releases duering night when there is less users. So I am trying to find a best way how to deploy changes into working system. If this is possible at all. Please be so kind and share your experiences. Oh, and I am not so tied to tomcat after all... thank you in advance, taavi --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 [INVALID FOOTER]
[Mav-user] Re: [OS-webwork] webwork, maverick and 24x7
Thank you all so far for these thoughs. Additional node and load balancer would be good solution of course and is definitely the right way to go. The only problem is that there is not too much load to balance :) I now feel that our users can live with the fact that the site is down for five minutes or so. But there is a lot of time consuming filling in data input forms going on in these applications. So I have to make sure that if I stop a webapp (the container itself remains running) then the application in root context will take over, persist all the form data and give an easy to understand explanation of what is going on. And once the new version of the webapp is deployed and is up and running again the user should be able to continue like nothing evere happened. This is just an idea and I dont know if this kind of solution is reliable. And would it work with different containers? With Tomcat it kind of works. The only worrying thing is that if I hit reload button heavily duering the startup of webapp then I have seen error messages. So it all depends on an implementation of a container and this can make things very vulnerable. taavi - Original Message - From: Rickard Öberg [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Friday, August 13, 2004 4:09 PM Subject: Re: [OS-webwork] webwork, maverick and 24x7 Taavi Tiirik wrote: I have two webapps using Webwork, Maverick, Tomcat 4.1, Hibernate, JSP views (but switching to freemarker soon).

Please be so kind and share your experiences. Yeah, we have the same problem and currently we try to find low-usage hours to do it. We'll be looking more at the 2-node cluster strategy Jason mentioned in the future. If you have the luxury of having static output you could always generate the HTML and shove them onto an Apache server. Then you can upgrade the dynamic stuff behind the covers. /Rickard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 [INVALID FOOTER]
[Mav-user] HttpServletRequestWrapper
Hi, I am using Throwaway2 type controllers and would like to plug in my own HttpServletRequestWrapper. What is the best way to do that in Maverick or should it be done outside Maverick with javax.servlet.Filter instead? many thanks, taavi --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 [INVALID FOOTER]
[Mav-user] hot to pass objects to include page
Hello,
This is not entirely maverick specific but I am trying to find a
solution to this in maverick environment hence the question.
I am currently using jstl as a view technology but if this can
be achieved with velocity and not with jstl then I am quite
ready to switch. Prefer to find a quick jstl solution though.
I would like to make my views more modular and reuse
common components as much as possible. For example
if I iterate over some sort of collection I would rather
include a component that knows how to render this
object instead of having similar rendering code in so
many places.
So instead of this:
c:forEach items=${model.projects} var=p
c:out value=${p.name}/, etc.
/c:forEach
I would like to have something like this: (does not work like this though)
c:forEach items=${model.projects} var=p
c:import url=/components/output-project.jsp
c:param name=project value=${p}/
/c:import
/c:forEach
and something like this in output-project.jsp:
c:out value=${param.project.name}/, etc.
This kind of approach works as far as I only pass simpe strings
but not with beans, etc. I need beans :)
So please tell me how do you do this?
best regards,
Taavi

Re: [Mav-user] Login with dynamic redirect
Scenario 2,
User types http://host/app/protectedCommand.m?p1=v1p2=v2p3=v3
Same idea, user is redirected to login and then if login is successfull
they
should be redirected through to initially selected command, only this time
there are a number of URL paramters that I wish to have set, Does anyone
have a simple way of acheiving this functionality.
David,
I dont know if you find it simple or elegant. My feeling is that it is not.
Anywhay
this is what I do:
in authentication-form.jsp I populate hidden fields into login form like
this:
c:forEach items=${paramValues} var=paramValue
c:forEach items=${paramValue.value} var=v
c:if test=${paramValue.key != 'loginName' paramValue.key !=
'loginPassword'}
input type=hidden name=c:out value=${paramValue.key}/
value=c:out value=${v}//
/c:if
/c:forEach
/c:forEach
This code filters out loginName and loginPassword since they are defined as
an
ordinary input fields.
I have this working with registration too. Ie. the user may happen to our
site, submit a
search form (not being logged in yet), find out that registration is needed,
register, and
then get search results. It really is necessary to remember these get or
post parameters
especially if session expires and user has filled in an input form and does
not want to
retype everything again.
with best wishes,
Taavi

[Mav-user] additional configuration for commands
Please enlighten me :-) I would like to specify some additional configuration parameters for my maverick commands in maverick.xml. Something like this is what I came up with: command name=orgunit controller class=ee.tvi.eris.ctl.orgunit.Orgunit param name=required-roles value=role1/ /controller ... /command This required-roles specifies that user must be authenticated and have role1 assigned to his/her account. Now this works but if I use views of type=redirect then this required-roles becomes an url parameter. Ie. if I define input view for this command like this: view name=input type=redirect path=orgunit-search.m/ then request to orgunit.m is redirected to: orgunit-search.m?required-roles=role1 I do not need this required-roles to go along with the redirect. Is there a better way to specify configuration parameters for a command. I do not want to have any additional config files, etc. with best wishes, Taavi --- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com [INVALID FOOTER]
[Mav-user] more dynamic LanguageShuntFactory
Hello, All! There is this LanguageShuntFactory that is just great for this kind of web applications where user never ever needs to switch between different languages. I have this feeling (maybe I am over-designing something here :) that in real world it needs some additional features... What I have in mind is a way how to override language selection that is made based on Accept-Language header. LanguageShunt.getView could just see if there is a session attribute (named language, etc.) defined. If there is, then it would first try to find a view for this particular language. Does it make sense? Do you think you would like this feature as well or is it only me? with best wishes, Taavi :-) Good I ran into Maverick.
