RequestLogger - logging page requests only

[Marios Skounakis]

Hi all,

I want to customize request logger to only log page requests. I.e. I don't
want resource requests, etc.

I have overridden log(RequestData rd, SessionData sd) as follows:

@Override
protected void log(RequestData rd, SessionData sd) {
if (rd.getResponseTarget() instanceof IPageRequestHandler)
super.log(rd, sd);
}

It seems to be working. Is there something I am missing?

Thanks
Marios

I can also try to pack the project as a jar file (so, that is is reusable)
and move it to wicket-stuff or some other place that gets regularly
published.

Re: Table with a lot of ajax links

[Ernesto Reinaldo Barreiro]

Hi,

Thanks for the feedback.

In fact, solution can be improved in many aspects. For instance, I thought
about making the "logic" pluggable so that you can support more that just
links... Maybe having a "handler" interface that can be registered on
"context" component and is responsible for

1- The header contributions needed by the "links". I write "links" because
they might be anything.
2- A method to  decides is a particular AJAX request can be handled by the
given handler.
3- A logic to deliver the event to the appropriate component(s).

This way we might have something "generic" and "extendable". For instance,
that could be used to register drag-drop events or anything you need.

If interesting to other people I can give it a try to this idea and publish
the code (and try to write something to explain the design). Mind example
is a table but behavior can be attached to "any"  component.

Re: [Announce] wicket-jade

[Decebal Suiu]

Hi Martin

I created a branch
https://github.com/decebals/wicket-jade/tree/children-components for your
idea.
I increased the complexity of demo application a little bit.
Now, the HomePage contains a BooksPanel that contains an AuthorPanel. Both
panels extend JadePanel.
BooksPanel.jade contains a div(wicket:id="authorPanel"). The markup for
authorPanel is AuthorPanel.jade.

Everything works fine.

Is this what you want or I misunderstand you? Can you explain your idea in
more words?

Best regards,
Decebal

Thank you very much, Ernesto.

I have a similar scenario, a panel with about 300 AjaxFallbackLinks and
each with some custom logic on the onClick, but your solution looks much
better.

Component for Applet

[Martin Beránek]

Hi,

I'am trying to write component similar to
http://mrhaki.blogspot.cz/2009/05/wicket-component-for-java-deployment.html
but I need to use JNLP for applet deployment. I write my own Resource
that generate JNLP file (it's xml, so I use JAXB and marschalling) and
I am also able generate script tag with appropriate content into html
page (onComponentTagBody).

My problem is url for resource. I don't know how to generate it - each
applet on my page (there can be more applets on one page) have to has
different JNLP so some shared resource can't be used.

Thanks for help

Hi,

I'd like to know if there is an official documentation for RequestLogger
anywhere?

I found several small bits on the net, but nothing that gives me a clue how
to actually do some logging.

I know that I have to initialise it somehow like this:

IRequestLoggerSettings requestLogger =
Application.get().getRequestLoggerSettings();
requestLogger.setRequestLoggerEnabled(true);

But where do I have to put this initialisation? I've put it into my apps
init() but it does nothing except creating an empty log file.

My log4j.properties:

log4j.category.org.apache.wicket.protocol.http.RequestLogger=INFO,RequestLog

Re: How to resolve this java.util.ConcurrentModificationException

[Martin Grigorov]

Hi,

Wicket 6.x has org.apache.wicket.core.util.objects.checker.IObjectChecker.
You may create your own one that doesn't allow serialization of LRUMap.
When such object is passed to ObjectOutputStream it will throw an exception
with nice message explaining the reference to this LRUMap.
This way you should be able to find which page keeps a ref to the LRUMap
See 
org.apache.wicket.serialize.java.JavaSerializer.SerializationCheckerObjectOutputStream#writeObjectOverride
for an example how to add your checker

Re: How to resolve this java.util.ConcurrentModificationException

[Dan Retzlaff]

There isn't much information in that stack. Why don't you subclass LRUMap
with a custom writeObject() implementation? Then you can breakpoint it, log
from it, and maybe throw NotSerializableException to trigger Wicket
SerializableChecker which gives nicer output. That way it triggers every
time the map is serialized, not just when a concurrent modification happens.

Re: How to resolve this java.util.ConcurrentModificationException

[saty]

Ok.. To explain the scenario, i have a singleton data-maanger java class that
user a underlying LRUMAP to store most recently viewed data. various wicket
panels use this data-manager to request data that they need to
display/update etc. 
Access to data is well protected using various synchronization techniques
and have no problem in that. The problem seems to be, is somehow wicket is
trying to serialize this LRUMAP which conflicts with application wring data
to it at that same time.

Re: How to resolve this java.util.ConcurrentModificationException

[Dan Retzlaff]

I'd use a debugger to look for live references to the map. In Eclipse, if
you right-click the variable line in the Variables view, there is an All
References option. The trick is instantiating the offending Wicket
component to create the reference. But once created it should stick around
at least until the next GC.

Re: How to resolve this java.util.ConcurrentModificationException

[Michael Mosmann]

IMHO nothing in Application is serialized. But its far to easy to leak 
an instance of this LRU-Map into some components (anon classes).


Can you provide some code or error message?

if i declare this as transient, will this prevent wicket from serializing

Thanks for your help.

Re: How to resolve this java.util.ConcurrentModificationException

I need to understand what and when Wicket tries to serialize stuff in a
running wicket application. I am not able to fix this error and it keeps
growing with more users starting to use the application. It does not affect
the application usage but it keeps beaming error email.

I am using LRU map to cache certain data being used in the application and
that is a shared data in a static context not tied to any particular user.
Why would wicket try to serialize this object, this should not be serialized
at all. LRU map this is not synchronized and is not thread-safe and
application code treats it that way but the serialization keeps generating
concurrent modification exception as its obvious its trying to serialize

if i declare this as transient, will this prevent wicket from serializing
this map too, what are the possible repercussion in wicket application if i
declare this transient.

Thanks for your help.

Re: [Announce] wicket-jade

[Decebal Suiu]

Hi Martin

I will try to implement your idea. I know about wicket-freemarker,
wicket-velocity. I didn't know about wicket-mustache. By the way I think
that your wicket-ractive project is interested (I like it because it's ajax
aware without a custom AjaxRequestTarget). I think that jade/haml syntax is
more html oriented than mustache syntax but it's my opinion. Fremarker,
Velocity, Mustache are more general.

Best regards,
Decebal

Re: [Announce] wicket-jade

[Martin Grigorov]

Hi Decebal,

I see you did something similar to what Wicket
Velocity
 and Wicket Mustache  do.
I think it would be much cooler if the Jade template/panel supports
children components, i.e. have div(wicket:id=someId) inside . For this you
will have to create a custom MarkupFactory and set it
with org.apache.wicket.settings.IMarkupSettings#setMarkupFactory().
Looking at the code I think Wicket is not well prepared for custom markup
factories but if you want to try it then I'll try to help you with
improvements in Wicket whenever you need such.

[Announce] wicket-jade

[Decebal Suiu]

Hi 

I implemented a tiny wicket-jade [1] integration solution. It's the first
version and it's a quick and dirty implementation (Proof of concept).
Jade [2] is a cool, high-performance (and probably the most used template
engine for Node.js)  template engine. I like the HAML-like syntax of Jade's;
it's very simple and intuitive.

Best regards, 
Decebal

Documentation for RequestLogger

[Jens Jahnke]

Hi,

I'd like to know if there is an official documentation for RequestLogger
anywhere?

I found several small bits on the net, but nothing that gives me a clue
how to actually do some logging.

I know that I have to initialise it somehow like this:

IRequestLoggerSettings requestLogger = 
Application.get().getRequestLoggerSettings();
requestLogger.setRequestLoggerEnabled(true);

But where do I have to put this initialisation? I've put it into my apps init() 
but it does nothing except creating an empty log file.

My log4j.properties:

log4j.category.org.apache.wicket.protocol.http.RequestLogger=INFO,RequestLogger
log4j.additivity.org.apache.wicket.protocol.http.RequestLogger=false
log4j.appender.RequestLogger=org.apache.log4j.RollingFileAppender
log4j.appender.RequestLogger.File=${catalina.home}/logs/wicket-requests.log
log4j.appender.RequestLogger.MaxFileSize=10MB
log4j.appender.RequestLogger.MaxBackupIndex=10
log4j.appender.RequestLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.RequestLogger.layout.ConversionPattern=%d{ISO8601} %-5p- 
%-26.26c{1} - %m\n


Regards,

Jens
