Why is using Tapestry a Filter instead of a Servlet
Hi, i was just curious about why Tapestry is using a Filter instead of a Servlet. Does anyone know? Regards garz - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Why is using Tapestry a Filter instead of a Servlet
A filter is passed a reference to the FilterChain which can ultimately pass through to the servlet container's own url resolution (ie a resource in the war). A servlet is an endpoint and must resolve the URL itself.

yes i know that, but it does not answer my question. :) On 26.02.2014, at 11:09, Lance Java lance.j...@googlemail.com wrote: A filter is passed a reference to the FilterChain which can ultimately pass through to the servlet container's own url resolution (ie a resource in the war).

Re: Why is using Tapestry a Filter instead of a Servlet
Well... You can have the Tapestry filter mapped to /* and it can play nicely with other servlets. http://tapestry.apache.org/configuration#Configuration-ConfiguringIgnoredPaths

beaneditor for complex object
Hi I'm trying to create edit form for my hibernate entities.
For example:
@Entity
@Table(name = SOME_OBJECT)
public class SomeObject implements Serializable {
...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = SUB_OBJECT_ID, nullable = false)
private SubObject subObject;
...
}
How could I create edit form for this entity, I tried this way:
div class=t-beaneditor
div
t:beaneditor t:object=someOBject t:exclude=id /
/div
div
t:beaneditor t:object=someOBject.subObject t:exclude=id /
/div
div class=t-beaneditor-row
input t:type=submit value=Save /
/div
/div
someOBject is marked as persisted, but the inner object bean edit form is not
there
Any ideas?

As Lance said, a servlet is and endpoint and it must send a response to a request. This causes servlets to be useless when you're trying to handle more than one URL pattern but not all. A servlet filter is way more flexible. You can have Tapestry code, specifically HttpServletRequestFilter, which has a chance to run some logic for every request, being it actually handled by Tapestry or not. One nice example would be to control access to images (or any other URL) located in the webapp context.

Re: beaneditor for complex object
You should either explicitly persist the inner object itself or add a
cascading option to the relationship mapping. This isn't related to
Tapestry at all, just to the way you're using Hibernate.

Re: Autocomplete exception blank query parameter.
Sounds like a webcrawler / bot to me. Do you have the apache logs? You could check the user agent header. As a fix, Google for the list of known bots and their user agent headers and customised tapestry's exception reporting so that exceptions are not logged for crawler user agents.
Re: Autocomplete exception blank query parameter.
Thanks for the reply lance. What does the actual exception mean? Does is it mean a request is being set with a missing parameter to the autocomplete component? I vaguely remember seeing this a long time ago while writing a custom autocomplete component. As far as the logs, I'm hosting the app on Amazons Elastic Bean Stalk, so finding the logs has proven to be a little difficult. They have a way to return the logs to you through the EBS interface, however they seem pretty useless since they do not appear to include my exception logs. I tried logging into the EC2 instance and directly access the logs, however amazon moved them out of the tomcat logs directory and I have yet to find them. The exception your seeing is what's being email to me and my phone is blowing up lol. In my custom exception page, how do I go about determine it's user agent? I really want to get these things on the ignore list. This one also appears to be a popular one. Input string 'w00tw00t.at.blackhats.romanian.anti-sec:)' is not valid; the character Thanks On Wed, Feb 26, 2014 at 8:22 AM, Lance Java lance.j...@googlemail.comwrote: Sounds like a webcrawler / bot to me.

Re: Autocomplete exception blank query parameter.
Some serverside actions (eg autocomplete) expect a well formed request which may require some request parameters to be present. As you can imagine, a bot can run regular expressions and hit anything the looks like a URL. I think it's fine to ignore crawlers from error logging. It's difficult to do much else. You could override / decorate the RequestExceptionHandler and check the User-Agent request header before logging https://tapestry.apache.org/overriding-exception-reporting.html http://user-agent-string.info/list-of-ua/bots
Re: beaneditor for complex object
Beaneditor doesn't handle nested entities. Beaneditor (or the underlying
BeanEditForm) renders an html form and nested forms are not allowed. One of
the simplest things you could do is to render just those field you actually
need to edit from the child object. Or, if you want a complete solution,
take a look at Tynamo's tapestry-model (
http://tynamo.org/tapestry-model+guide).
