Injecting proxy services in page.
We are doing the "annotation based approach" described in this link
(https://cwiki.apache.org/WICKET/spring.html). At least, we think we are.
We get:

I thought this might be because that particular service is in the parent
page object and annotated there as well, but I moved it to the child class
and saw no change in behavior. It is a hibernate service and is annotated
in the page like so:
@SpringBean(name="LogTransService")
private LogTransService userTransService;
The exception happens when I go to the page, do a few things (which involve
submitting and redisplaying the page), and then hit the browser back button.
This, as I understand it, causes wicket to deserialize the page from memory.
But shouldn't it see the @SpringBean and re-inject a new service?
Out app object does this:
addComponentInstantiationListener(new SpringComponentInjector(this,
ctx, true));
Ideas?

Hi,
I don't use Spring, so I can't help you specifically. However, there is
a chapter about integration with Spring in the free wicket guide here:
https://code.google.com/p/wicket-guide/
(chapter 17.2)

Re: Injecting proxy services in page.
Posted by "martin.dilger" <ma...@googlemail.com>.
To be honest, I dont understand exactly what the Problem is.
If you work with Spring-Beans, they are normally safe to serialize, as its
only the proxy.
We´ve done this all the time (even with older wicket versions) without any
problems.
It looks like you have some Classpath-Issue here. The Service-Class you
mentioned, is that an Interface or do you work with the concrete
Implementation. I got similar Issues when working with
Implementation-Classes and CGLib.

Re: Injecting proxy services in page.
Posted by eugenebalt <eu...@yahoo.com>.
We've heard that there is a fix for this available in Wicket 1.5.
However, we are stuck with Wicket 1.4.7 and cannot upgrade, for various
reasons. (We're also already using the AnnotationConfigWebApplicationContext
referred to in the previous post.)
Are there any other workarounds for this problem? Is it OK to make the
problem classes "implement Serializable" just to move past this issue (even
if they are injected with the @SpringBean, and are service classes), or
should we try other workarounds?

If you are already using XmlWebApplicationContext (extends
AbstractRefreshableWebApplicationContext like
AnnotationConfigWebApplicationContext) that is probably not the issue, but
you can set the context class in your web.xml like this:
<servlet>
...
<init-param>
<param-name>contextClass</param-name>
<param-value>
org.springframework.web.context.support.AnnotationConfigWebApplicationContext
</param-value>
</init-param>
</servlet>

At the risk of turning this into a Spring discussion on a Wicket forum, how
does one control that? I would like to try your suggestion, but am not sure
what knob to twist.
We just implement ApplicationContextAware, and point to our spring config
file in web.xml. I don't set anywhere asking for a particular KIND of
appcontext to be used. When it hands it to me, it is
XmlWebApplicationContext.

Hi,
I'm not sure if this is the issue here but I've seen similar problems
when I used AnnotationConfigApplicationContext as a Spring context, but
got it working by using AnnotationConfig*Web*ApplicationContext.

RE: Injecting proxy services in page.
Posted by Paul Bors <pa...@bors.ws>.
I find it easier to configure Spring via the XML rather than code.
Hence I have my applicationContext.xml inside my war's WEB-INF/classes/ with
all the bean definitions and then configure Wicket via the context specific
configuration from inside my web.xml:
<!--
There are three means to configure Wickets configuration mode and
they
are tested in the order given.
1) A system property: -Dwicket.configuration
2) servlet specific <init-param>
3) context specific <context-param>
The value might be either "development" (reloading when templates
change) or
"deployment". If no configuration is found, "development" is the
default. -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<filter>
<filter-name>persistence</filter-name>
<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFil
ter</filter-class>
<init-param>
<param-name>entityManagerFactoryBeanName</param-name>
<param-value>entityManagerFactory</param-value>
</init-param>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
...
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</liste
ner-class>
</listener>
Whenever I need to inject a service I use Wicket's @SpringBean.
