WicketNotSerializableException
Dear all,
I got this message because there is a field that Wicket wants to
serialize but it can not be serialized. Now how do I remove this error
since I can not make tomcat's ApplicationContextFacade to be
Serializable.
2007-12-17 17:49:12,498 - [ERROR] - Objects - Error
serializing object class com.mycompany.dupe.pages.PricePage
[object=[Page class = com.mycompany.d
upe.pages.PricePage, id = 17, version = 0]]
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class:
org.apache.catalina.core.ApplicationContextFacade
Field hierarchy is:
17 [class=com.mycompany.dupe.pages.PricePage, path=17]
private java.lang.Object
org.apache.wicket.MarkupContainer.children [class=[Ljava.lang.Object;]
private java.util.List
com.mycompany.dupe.pages.PricePage$PriceForm.prices[8]
[class=com.mycompany.dupe.pages.PricePage$GeneratorForm, path=17:generatorForm]
javax.servlet.ServletContext
com.mycompany.dupe.pages.PricePage$GeneratorForm.context
[class=org.apache.catalina.core.ApplicationContextFacade] <----- field
that is not serializable
Thanks in advance

Thanks Igor,
I get the clear picture now, I'll make a workaround from your advice.
I currently have problems with reference object that came from other
libs that is not Serializable.
Best Regards,

anything that a page keeps reference to, directly or indirectly, needs
to be serializable. for objects that are not serializable you should
do what loadabledetachablemodel does: keep an object as a transient
variable and have a way to look it up if its null. ive built a lot of
stuff with wicket and this hasnt been a problem yet. sometimes i had
to wrap or subclass objects that came from other libs because the devs
didnt bother to make those objects serializable - not everyone thinks
about this stuff - but other then that nothing major.

Looks like that this problem is viral. How do I work with objects that
is not Serializable while on the other hand wicket want it to be
Serializable?

see SpringWebApplcation, it has methods to create same proxies @SpringBean does.

Hi All,
I have take a loot at this. But is there any solution to fix this
without using @SpringBean since I am still on JDK1.4.
Thanks in advance

it's the ApplicationContextFacade that can't be serialized. you'll need to
mark this field as transient most likely. Now, if this is, as I suspect, a
spring class for getting your dependencies, you'll have to refetch/recreate
this context after deserialization. But if you're using spring you should
really look at wicket-spring and use @SpringBean to get your deps handed to
you.
