null lastPage at restoreAfterSerialization
Hi all,

heavy loaded production environment, permanent errors with a trace

Help with load-balancing and fail-over in a Hibernate, Spring, Wicket 3-tier architecture
Hi, I have this 3-tier architecture in mind: 1. Persistence: Hibernate with MySQL 2. Business: Spring 2.5 3. Presentation: Wicket I want my application to have high availability and scalability, so I want to cluster it with load-balancing, fail-over and synchronization. I wonder if you know of any nice tutorial which will educate me on the subject? And if not, if you can give me some pointers of what I need to do. I have some questions below, if you know of something I haven't thought to ask about feel free to educate me further. I've found it hard to find concrete information regarding this topic. 1. Do I have to run this inside a Java EE server or is it possible using Tomcat? 2. Should I run this inside a Java EE server? I have used JBoss 4.x, maybe I should use it? I have seen suggestions for deployment architectures similar to this one: [Active load balancer] - [Backup load balancer] | [WebServer1] , [WebServer2] , ... [WebServerN] | [MySqlServer1] , [MySqlServer2] , ... [MySqlServerN] 3. What should I use for load balancer? (I know there are multiple load balancing strategies.) 4. I've heard that WebServer1, ... , WebServerN should be synchronized, use fail-over and be load-balanced. Exactly what do I have to synchronize? How is that achieved? 5. I've also heard that MySqlServer1, ... , MySqlServerN should be synchronized, use fail-over and be load-balanced. Exactly what do I have to synchronize? How is that achieved? 6. In the past I've only a 3-tier architecture based on JPA, EJB (Stateless session beans) and JSP+Servlet for Persistence, Business and the Presentation layers. Pure Hibernate (I've used JPA with Hibernate as persistence provider) is new to me, Spring 2.5 is new and Wicket is new. Also creating a clustered solution like this is new to me. :-) I'm a bit afraid that there are too many new components for me to handle. Wicket seems easy enough, I'm reading Wicket in Action. Do you think I should change any of the other components into components I've used before, as the new components requires a high learning investment? (I should also make a note of that I am not entirely satisfied with Java EE in its current version.) If you've read this far, thank you! I'm a bit lost at the moment as solutions with high availability and scalability are new to me, I would really appreciate any help I can get.

Wicket 1.3.5 behind a front-end proxy
Hi, http://cwiki.apache.org/WICKET/wicket-behind-a-front-end-proxy.html shows this configuration: VirtualHost ordering.company.com ProxyPass / http://appserver.company.com:8080/ordering/ ProxyPassReverse / http://appserver.company.com:8080/ordering/ # Apache 2.2+ only ProxyPassReverseCookiePath /ordering / /VirtualHost as impossible until getApplicationSettings().setContextPath(/); But it says in 1.3 it must work because it uses relative paths. My experience shows that contextPath is still added in URL in links and I don't know why. Was anyone successfull in deploing Wicket 1.3.5 when Tomcat is used by Apache through mod_proxy? If yes, please, send me example of configuration. What I need to do in web.xml? Thank you, Tony. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Model never called
you should rather add an IModel to the link e.g. new Link(foobar, myModel);
than letting a component implement IModel. the way you did it, the model is
never recognised as a model, as it wasn't set as a model of a component.
hope that makes sense

Re: null lastPage at restoreAfterSerialization
The last one of the saga for now, I badly need to sleep.
I've been sampling tomcat work dir every second:
i=0; while [[ i -le 300 ]]; do echo $i; ls -lt /u01/tomcatWork/_
/tmp/work$i; sleep 1; i=$((i + 1)); done
Then I greped a number of session ids corresponding to
restoreAfterSerialization errors and every one of them appears in zero
or one samples at most. With maxIdleTime = 120 secs the pattern is
this:
/u01/tomcatWork/_/wicketServlet-fileStore/sessionid created at
T - 120 secs
/u01/tomcatWork/_/sessionid.session
swapped out at T - serialized
restoreAfterSerialization error
expired at ~T - deserialized
The life span of /u01/tomcatWork/_/sessionid.session is of a
fraction of a second. So the problem seems to be definitely related to
short lived sessions that are removed immediately after being swapped
out. The session is removed sooner than expected because of the
exception that is thrown attempting to deserialize the lastPage. This
is clear from inspection of tomcat's StoreBase.processExpires:
try {
StandardSession session = (StandardSession) load(keys[i]);
-- load fails
.
if (session.isValid()) {
continue; -- ideally we should be here
}
.
remove(session.getIdInternal());
} catch (Exception e) {
.
remove(keys[i]); -- but instead
/u01/tomcatWork/_/sessionid.session is prematurely removed here
}

Field value null on Submit after onUpdate()
Hi, Everyone!
I wrot this Ajax Event Handler for a AutoCompleteTextField:
@Override
protected void onUpdate(AjaxRequestTarget target)
{
ChildObj co = (ChildObj)AutoCompleteTextField.findChoice();
if(null != co )
{
((Obj)Form.getModelObject()).setChildObject(co);
((Obj)Form.getModelObject()).setPrice(co.getPrice());
if(co.isBoolAttribute())
{
((Obj)Form.getModelObject()).setAmount(new Float(1));
TextInput.setEnabled(false);
target.addComponent(TextInput);
}
else
{
((Obj)Form.getModelObject()).setAmount(new Float(1));
obj.setAmount(new Float(1));
TextInput.setModelObject(new Float(1));
TextInput.setEnabled(true);
target.addComponent(TextInput);
}
}
}
This is working as long as the else-block is not executed bu when I submit
the Form including the AutoCompleteTextField and the TextInput both
AutoCompleteTextField and TextInput have a NULL value.
Someone please help me what's wrong.

Nope, doesn't work either.
I've created a new class MySquare implementing IModel but the getObject() never
get called either.
I'm stumped.
In populateItem I do:
for (int col=0; col10; col++) {
MySquare mySquare = new MySquare();
Link link = new Link(cols+col, mySquare) {
public void onClick() {
System.out.println(clicked);
}
};
link.add(new Image(icon+col,Square.emptyResource));

AjaxUpdate broken after showing feedback in ModalWindow
Hi all, I have a ModalWindow with some radios in it. Everytime a Radio is selected, an AjaxEventBehavior(onclick) is called which updates a special RadioGroup in that page. Everything works fine, as long as there are no errors and no feedback is shown. If I produce an Error, in that case it´s a RadioGroup where none of the Radios is selected, the feedback shows up. Now, when I select a Radio, the AjaxEventBehavior(onclick) is called, works through the code, but does not refresh the target(-radios). Debugging shows that the values are set correctly, but they won´t be shown. Is this a bug, or am I doing something terribly wrong?

RES: Model never called
I couldn't understand the part about the icon, but what I know is that
'getObject()' will *never* be called until you set the Square object into
itself as the model:
public Square() {
setModel(this);
}

Assunto: Model never called
Hi,
I do have a link class which should render different icons when clicked.
So I decided to implement IModel and return different icons depending on the
state of the object. But to my surprise getObject() never get called!
Does anyone give me a clue where to look next or give me a hint as to how to
render the object with a different icon?
The object is used in a 10x10 board game where a player can shoot at
different squares which are rendered as links in the output. The board is
constructed as:
ListView listview = new ListView(rows, list) {
private static final long serialVersionUID = 1L;
protected void populateItem(ListItem item) {
Row row = (Row) item.getModelObject();
final Square[] squares = new Square[10];
for (int col=0; col10; col++) {
squares[col] = row.getCells(col);
}
Square square = row.getCells(0);
item.add(new Label(row,new
Model(square.getRow(;
for (int col=0; col10; col++) {
final Square aSquare =
row.getCells(col);
item.add(aSquare);
}
}
};
And the Square-Object is:
public class Square extends Link implements IModel {
@Override
public void onClick() {
System.out.println(Click: + ident);
}
@Override
public Object getObject() {
System.out.println(GetObject);
if (someState)
return icon1;
return icon2;
}
}

Re: Help with load-balancing and fail-over in a Hibernate, Spring, Wicket 3-tier architecture
Can mysql really load balance like that? How does it work with transactions and so on? Normally you scale the webservers and have 1 big database server thats serves all of them. For wicket you just need tomcat with sticky sessions. Then you only have to take care of the hibernate caching on each tomcat instance On 11/19/08, Kent Larsson [EMAIL PROTECTED] wrote: Hi, I have this 3-tier architecture in mind: 1.

I have some questions below, if you know of something I haven't thought to ask about feel free to educate me further. I've found it hard to find concrete information regarding this topic. 1.

Do you think I should change any of the other components into components I've used before, as the new components requires a high learning investment? (I should also make a note of that I am not entirely satisfied with Java EE in its current version.) If you've read this far, thank you!

Noob question: Wicket and statefull/stateless
Pardon the (possible stupid) question, I'm new to Wicket but is quite
excited about the simplicity it seems to promote over JSF.
What's the usual way of pushing context on to a website and have it passed
along, such as to remain stateless? In JSF you would typically create a
request scoped backing bean and create some hidden inputs on the webpages
which can hold relevant id's or even base64 encoded and encrypted model
data. I thought perhaps Wicket were able to do this transparantly, as
suggested by the following example:
// LetterChoice.java
final ListString someLetters = Arrays.asList(A, D, C);
final DropDownChoice letter = new DropDownChoice(letter, new
ModelString(), someLetters);
StatelessForm form = new StatelessForm(keyForm) {
@Override
protected void onSubmit() {
setResponsePage( new LetterResult( someLetters,
Integer.parseInt( letter.getValue() ) ) );
}
};
// LetterResult.java
public LetterResult(ListString someLetters, int letterId) {
String selectedLetter = someLetters.get( letterId );
}
It appears you can pass both the model as well as the selection on to a
new page, but there's no special/hidden content in the generated
LetterChoice webpage. Does this simply mean what I am doing i tied to my
session by Wicket? Is there a way ensure there's no (or just a bare
minimum) of session state between each request? In general, what is the
mission goal when it comes to statefullness/statelessness of Wicket?
Thanks in advance,

LinkTree Add Children on Node Expansion
Hi, I want to use LinkTree and I want to add a node's children on its expansion in server side (like what we can do in Swing). I also want the junction link show the '+' icon on every node which its 'allowsChildren' is true, and on its expansion if no child provided, its junction link changes to a junction corner (like Swing). How can I do that?
Re: ajax busy indicator never stops in IE
I observed this behaviour too, but currently that issue doesn't have the
highest priority for me. I just wanted to give you a hint: I know it was
working in some wicket versions before 1.3.5 maybe it'll be a good start to
have a look at the JS involved and compare it with different wicket versions
... and then come up with a patch :-)

Andy, If I read this correctly, this is not a security precaution, but a don't shoot yourself in the foot switch. (Note the 'yourself'.) So if set up the right way, you don't need this at all.

Re: Model never called
A model is only in a link as a convenience for YOU to use. It's not used by
default - what about a link needs a model? Rather, it's for something like:
new Link(deleteUser, modelContainingUser) {
onClick() {
userDAO.delete(getModelObject());
}
}
It's for YOU to use. For instance, let's make a simpler example supposing
that you were changing the state of a label (rather than an image) with your
link. You could do something like this:
ModelString model = new ModelString(default value);
Link link = new Link(link, model) {
public void onClick() {
System.out.println(clicked);
setModelObject(I've been clicked);
}
}
link.add(new Label(label, model));
item.add(link);
The Label calls getObject() on its model because it needs data to print.
Since you share the model between the two, changing it in the link will
change it in the label.
Now, back to your image example - images use image resources, not models,
and I don't think this will work like you have it drawn. You need to
experiment with image resources for that. Hopefully this gives you a better
understanding of models, though.

Betreff: Re: Model never called
you should rather add an IModel to the link e.g. new
Link(foobar, myModel);
than letting a component implement IModel. the way you did
it, the model is
never recognised as a model, as it wasn't set as a model of a
component.
hope that makes sense

Re: resource mapping and dot in url
That has only to do with how IIS looks up which script to execute, and nothing to do with security.

Re: Noob question: Wicket and statefull/stateless
Ok. It sounds like the general philosophy behind Wicket is server side
statefulness. I was kind of hoping this was not the case. Just out of
curiosity, haven't anyone tried serializing and embedding state out on the
webpage that could then be POST'ed between requests - a kind of hybrid model
between session and request scope? This homemade hybrid seems to work for
JSF, though oddly not an official strategy.

Re: Noob question: Wicket and statefull/stateless
No worries - you're right - Wicket is designed to manage state for you, so
it's strength is not statelessness. But, you should really evaluate if you
have the need for stateless before constraining yourself to it. As long as
you use models correctly, you can support thousands of concurrent sessions
on a server simultaneously, and you can use the strength of Wicket - letting
it handle state for you.

What's the usual way of pushing context on to a website and have it
passed
along, such as to remain stateless? In JSF you would typically create a
request scoped backing bean and create some hidden inputs on the
webpages
which can hold relevant id's or even base64 encoded and encrypted model
data. I thought perhaps Wicket were able to do this transparantly, as
suggested by the following example:
// LetterChoice.java
final ListString someLetters = Arrays.asList(A, D, C);
final DropDownChoice letter = new DropDownChoice(letter, new
ModelString(), someLetters);
StatelessForm form = new StatelessForm(keyForm) {
@Override
protected void onSubmit() {
setResponsePage( new LetterResult( someLetters,
Integer.parseInt( letter.getValue() ) ) );
}
};
// LetterResult.java
public LetterResult(ListString someLetters, int letterId) {
String selectedLetter = someLetters.get( letterId );
}
It appears you can pass both the model as well as the selection on to a
new page, but there's no special/hidden content in the generated
LetterChoice webpage. Does this simply mean what I am doing i tied to my
session by Wicket? Is there a way ensure there's no (or just a bare
minimum) of session state between each request? In general, what is the
mission goal when it comes to statefullness/statelessness of Wicket?
Thanks in advance,

Re: Noob question: Wicket and statefull/stateless
He's not suggesting going stateless. He's suggesting an alternate way
of maintaining state (by pushing it to the client in hidden fields).
Tapestry supports (or supported) this as an option, but it made for
some pretty gnarly URLs (all the state had to be appended to the end)
for links. On forms, though, it wasn't that bad. The user never knew
it. To use this methodology effectively, I believe you have to go
into the everything is a POST land. Of course, I guess you could
get creative with redirect-after-post and using flash memory.

No worries - you're right - Wicket is designed to manage state for you, so
it's strength is not statelessness. But, you should really evaluate if you
have the need for stateless before constraining yourself to it. As long as
you use models correctly, you can support thousands of concurrent sessions
on a server simultaneously, and you can use the strength of Wicket - letting
it handle state for you.

Re: Help with load-balancing and fail-over in a Hibernate, Spring, Wicket 3-tier architecture
Can mysql really load balance like that? How does it work with transactions and so on? I think so, but I don't know much about it as I haven't read the white paper yet. Here is a link: http://www.mysql.com/products/database/cluster/ Normally you scale the webservers and have 1 big database server thats serves all of them. But I would really like some fail-over on the database side as well. If I can help it I don't want any single point of failure. For wicket you just need tomcat with sticky sessions. Then you only have to take care of the hibernate caching on each tomcat instance Thank you! I'll read up on tomcat with sticky sessions. What do you mean with take care of hibernate caching on each tomcat instance? To have them synchronized as well?

I wonder if you know of any nice tutorial which will educate me on the subject? And if not, if you can give me some pointers of what I need to do. I have some questions below, if you know of something I haven't thought to ask about feel free to educate me further. I've found it hard to find concrete information regarding this topic. 1.

[WebServerN] | [MySqlServer1] , [MySqlServer2] , ... [MySqlServerN] 3. What should I use for load balancer? (I know there are multiple load balancing strategies.) 4. I've heard that WebServer1, ... , WebServerN should be synchronized, use fail-over and be load-balanced. Exactly what do I have to synchronize? How is that achieved? 5. I've also heard that MySqlServer1, ... , MySqlServerN should be synchronized, use fail-over and be load-balanced. Exactly what do I have to synchronize? How is that achieved? 6.

Pure Hibernate (I've used JPA with Hibernate as persistence provider) is new to me, Spring 2.5 is new and Wicket is new. Also creating a clustered solution like this is new to me. :-) I'm a bit afraid that there are too many new components for me to handle. Wicket seems easy enough, I'm reading Wicket in Action. Do you think I should change any of the other components into components I've used before, as the new components requires a high learning investment? (I should also make a note of that I am not entirely satisfied with Java EE in its current version.) If you've read this far, thank you! I'm a bit lost at the moment as solutions with high availability and scalability are new to me, I would really appreciate any help I can get.

Re: swarm wicket 1.4
Hi, we've not decided here whether we'll use SWARM for our security needs for our super duper new online app (!). I think next month will be taking a long look at this as see if it fits the needs etc. I was also looking at jsecurity but theres no documentation and Les has yet to fully integrate into wicket. Getting SWARM to work with 1.4 m3 was no problem, just a couple of code changes, and it works as expected. If we commit to swarm then of course we can try and keep it more up to date.

Re: Noob question: Wicket and statefull/stateless
We tried that once, to have state transfered to the client, we didnt

Cpu time and bandtwidth is way more expensive then memory. Wicket
takes now memory on the server but the overhead it would generate by
serializing and base64 every page into the result and the other way

Did you encounter any real issues with state on the server or is this

FileUploadField usage changed in 1.4 rc-1?
Hi!
My FileUploadField worked fine before:
dataForm.add(fileUploadField = new FileUploadField(COMPANY_LOGO));
After upgrading to 1.4 rc-1 (from 1.4-m1) the upload crashes.
Am I doing something wrong or is there a bug in rc-1?

}
}
However, this hasExplicitModel is not there anymore in 1.4-rc1

Re: Noob question: Wicket and statefull/stateless
Yes we've experienced issues with multiple browser windows as well as
synchronization of shared session resources. Again, this has nothing to do
with optimization but everything to do with craving a solid, simple
programming model for frontend developers.

Re: Noob question: Wicket and statefull/stateless
It might be good to try to ask specific questions about those issues that
you've seen. You will get good help here on the list, and from my
experience, you won't get a much better / simpler programming model than
what Wicket gives you. I've used Tapestry, where everything was stuffed
into the urls and it was a nightmare creating truly reusable components that
could be used anywhere. With Wicket, it's just not that way.
Anyway, your use case sounds intriguing - what issues are you seeing?
Probably something simple that you could do different - must simpler than
managing state yourself.

Cpu time and bandtwidth is way more expensive then memory. Wicket
takes now memory on the server but the overhead it would generate by
serializing and base64 every page into the result and the other way
around is just way way to expensive.
Did you encounter any real issues with state on the server or is this
again premature optimization??

Ok. It sounds like the general philosophy behind Wicket is server side
statefulness. I was kind of hoping this was not the case. Just out of
curiosity, haven't anyone tried serializing and embedding state out on
the
webpage that could then be POST'ed between requests - a kind of hybrid
model
between session and request scope? This homemade hybrid seems to work
for
JSF, though oddly not an official strategy.
I actually just joined the mailinglist and posted, after not seeing my
message show up after 24h I tried posting again - this time it worked. I
apologize, now posting via Napple - latency and behavior somewhat more
deterministic.

Anyway, for completely stateless page transitions, etc, and how to put
data
into the URL rather than session, you need to use BookmarkablePageLink,
which will invoke the YourPage(PageParameters) constructor. Give those
a
shot. For forms that put their data in the URL, search the list on
nabble
- there's been two threads this week dealing with it. Basically, mount
a
bookmarkable page, don't use a Wicket form, just use an HTML form, and
make
it do a GET to the bookmarkable page URL. You can then use the
YourPage(PageParameters) constructor again.

Pardon the (possible stupid) question, I'm new to Wicket but is quite
excited about the simplicity it seems to promote over JSF.
What's the usual way of pushing context on to a website and have it
passed
along, such as to remain stateless? In JSF you would typically create
a
request scoped backing bean and create some hidden inputs on the
webpages
which can hold relevant id's or even base64 encoded and encrypted
model
data. I thought perhaps Wicket were able to do this transparantly, as
suggested by the following example:
// LetterChoice.java
final ListString someLetters = Arrays.asList(A, D, C);
final DropDownChoice letter = new DropDownChoice(letter, new
ModelString(), someLetters);
StatelessForm form = new StatelessForm(keyForm) {
@Override
protected void onSubmit() {
setResponsePage( new LetterResult( someLetters,
Integer.parseInt( letter.getValue() ) ) );
}
};
// LetterResult.java
public LetterResult(ListString someLetters, int letterId) {
String selectedLetter = someLetters.get( letterId );
}
It appears you can pass both the model as well as the selection on to
a
new page, but there's no special/hidden content in the generated
LetterChoice webpage. Does this simply mean what I am doing i tied to
my
session by Wicket? Is there a way ensure there's no (or just a bare
minimum) of session state between each request? In general, what is
the
mission goal when it comes to statefullness/statelessness of Wicket?
Thanks in advance,
Casper

Re: Wicket 1.3.5 behind a front-end proxy
What is the problem you are having, we use mod_proxy in several environments with wicket / tomcat. Jeremy I have several apps on one hosting and several domains (aliases) that must be directly connected to corresponding Web App/. Configuration is this: ServerAlias wicket.ru ProxyPass /stats/ ! ProxyPass /webmail/ ! ProxyPass /lxadmin/ ! ProxyPass / ajp://localhost:8858/WicketRu/ ProxyPassReverse / ajp://localhost:8858/WicketRu/ ProxyPassReverseCookiePath /WicketRu / The problem is with mapping domain alias directly to Web Application so that context name is invisible. Index page is shown but Links still contain contex name. Test: open wicket.ru and click it's title it shows HTTP Status 404 - /WicketRu/WicketRu/ type Status report message /WicketRu/WicketRu/ description The requested resource (/WicketRu/WicketRu/) is not available. Apache Tomcat/6.0.18 Filter mapping is filter-mapping filter-namewicket.ru/filter-name url-pattern/*/url-pattern /filter-mapping Wicket 1.3.5 is used.

Assunto: FileUploadField usage changed in 1.4 rc-1?
Hi!
My FileUploadField worked fine before:
dataForm.add(fileUploadField = new FileUploadField(COMPANY_LOGO));
After upgrading to 1.4 rc-1 (from 1.4-m1) the upload crashes.
Am I doing something wrong or is there a bug in rc-1?
Caused by: java.lang.IllegalStateException: Attempt to set model

The 1.4-m-3 code avoided the nullpointer like this:
@Override
public void updateModel()
{
// Only update the model if one was passed in
if (hasExplicitModel)
{
setDefaultModelObject(getConvertedInput());
}
}
However, this hasExplicitModel is not there anymore in 1.4-rc1
No documentation seems to have changed..

Re: Reading an attribute that is set in a CSS file as a class

Then I greped a number of session ids corresponding to

this:

/u01/tomcatWork/_/sessionid.session
swapped out at T - serialized
restoreAfterSerialization error
expired at ~T - deserialized
The life span of /u01/tomcatWork/_/sessionid.session is of a
fraction of a second. So the problem seems to be definitely related to
short lived sessions that are removed immediately after being swapped
out. The session is removed sooner than expected because of the
exception that is thrown attempting to deserialize the lastPage. This
is clear from inspection of tomcat's StoreBase.processExpires:
try {
StandardSession session = (StandardSession) load(keys[i]);
-- load fails
.
if (session.isValid()) {

TextField pgLongLimit = new TextField(pgLongLimit, new PropertyModel(
pglimit, longLimit));
pgLongLimit.setRequired(false);
pgLongLimit.setLabel(new Model(Long Limit));
validator.addNumberRange(pgLongLimit, 0,
Integer.MAX_VALUE);
My classname.properties file looks has following code:
NumberValidator.range = ${label} should have a positive integer value
Now whenever I put in a negative input I get the correct error i.e Long
Limit should have a positive integer value.
However if I put in a char value as an input (say 'a') then the error is a
is not a valid int. I want to change this error to something like Invalid
input.
Any ideas about how I can do that. I don't know which resource key I would
have to use here.
Thanks,
vishy

Re: Validation Question
Vishy,
Add
IConverter=Invalid Input
to a properties file in, for example, MyApplication.properties for your
whole application or in MyPage.properties if you want this custom message on
a particular page only ... etc, in the same package as the class with the
same name.

Re: null lastPage at restoreAfterSerialization
Hi Matej,
I'm browsing your changes. Please notice that according to my own
debugging it's lastPage itself that is null and not only the result of
prepareForSerialization. So I don't think the warning PageStore
prepared non-null page as null for serialization will ever be
reached. Anyway, I will add other warnings and keep you informed of
the output as soon as I can. This is really tricky to debug because up
til today I'm only able to reproduce it at full scale in a production
environment.
Do you have any idea why a lastPage would be null after 120 secs of
the request that created the session? Specially for sessions that
don't survive that first request. An exception that could avoid
request cycle to detach the session maybe?
Thanks!

This really is weird. I added couple of warnings and null check to 1.4

The last one of the saga for now, I badly need to sleep.
I've been sampling tomcat work dir every second:
i=0; while [[ i -le 300 ]]; do echo $i; ls -lt /u01/tomcatWork/_
/tmp/work$i; sleep 1; i=$((i + 1)); done
Then I greped a number of session ids corresponding to
restoreAfterSerialization errors and every one of them appears in zero
or one samples at most. With maxIdleTime = 120 secs the pattern is
this:
/u01/tomcatWork/_/wicketServlet-fileStore/sessionid created at
T - 120 secs
/u01/tomcatWork/_/sessionid.session
swapped out at T - serialized
restoreAfterSerialization error
expired at ~T - deserialized
The life span of /u01/tomcatWork/_/sessionid.session is of a
fraction of a second. So the problem seems to be definitely related to
short lived sessions that are removed immediately after being swapped
out. The session is removed sooner than expected because of the
exception that is thrown attempting to deserialize the lastPage. This
is clear from inspection of tomcat's StoreBase.processExpires:
try {
StandardSession session = (StandardSession) load(keys[i]);
-- load fails
.
if (session.isValid()) {
continue; -- ideally we should be here
}
.
remove(session.getIdInternal());
} catch (Exception e) {
.
remove(keys[i]); -- but instead
/u01/tomcatWork/_/sessionid.session is prematurely removed here
}

Another fact that could be relevant is that this only happens upon
processexpires, but never for swapin, which seems to suggest that the
span of the sessions that fail to restore is just one request (maybe
the ones coming from bots that don't support cookies).

Hi
Im trying todo a compoundpropertymodel which does not change original
values in the original model. I need this since I am updating some
stuff
in a wizard but I first want to commit when the user confirms in the
end of
the wizard, and if the model are changed directly the transaction are
automatically committed to the database
So my idea were to todo a shadowCompoundPropertyModel something like
this:
class EditorModel extends CompoundPropertyModel {
private Map newValues=new HashMapString, Object();
public EditorModel(CompoundPropertyModel underlyingModel,
String propertyName) {
super(underlyingModel);
}
public getObject (String property){
check if there are something in the map if so return it, otherwise fall
back to the underlying model
} public setObject (String prop, Value){
put changes in the map...
}
public UpdateOriginal(){
iterate over the map and use reflection to set values on the original
model..
}
}
Does anybody have something similar floating around, in a more complete
state..? Or could it be done in a easier way?

I'll repeat the problem: Application is WicketRu. It works correctly when accessed through full URL. Alias is wicket.ru http://wicket.ru opens. But links don't work. wicket.ru on the top is a Link with onClick() and setResponsePage(Index.class). Click on it shows 404 with ***strange*** ***double WicketRu.
