Re: Adding to response header (filename)?
I've changed it to that below, but still get 18:22:47,185 ERROR WebResponse:190 - Unable to redirect to: ?wicket:interface=:2, HTTP Response has already been committed. in the logs. Isn't this the same as what's in the link you posted? I can post all the code, but all it is is a Link inside a Form. The code before what I've posted below simple appends text to the out, which is a StringBuilder. This is the only part where I send the request. I'm using 1.3 Wicket, and Apache Tomcat 6, if that helps. SimpleDateFormat formatFile = new SimpleDateFormat(MM-dd-); ResourceStreamRequestTarget rsrt = new ResourceStreamRequestTarget(new StringResourceStream(out, text/csv)); rsrt.setFileName(export_ + formatFile.format(Calendar.getInstance().getTime()) + .csv); getRequestCycle().setRequestTarget(rsrt); Jan Kriesten wrote: hi, see here: http://www.nabble.com/Download-link-from-DynamicWebResource--tf4353363.html#a12404601 regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Justin Stanczak Stanczak Group 812-735-3600 All that is necessary for the triumph of evil is that good men do nothing.

Well, I still don't see a way to get around this error. I'll have to
live with it for now until I can look into it deeper. Has anyone else
had this error?

Re: Yanıt: Re: Adding to response header (filename)?
That's what I used to use, but it gives the same error. Do you not get
the error in the logs. The error doesn't stop it from working, but I
still would like to do it correctly according to Wicket.

But you shouldn't call respond yourself. That's for Wicket to do. The
only thing you should do is the the request target on the request
cycle.

In your application class:
@Override
public RequestCycle newRequestCycle(Request request, Response response)
{
return new WebRequestCycle(this, (WebRequest)request, response)
{
@Override
protected void onBeginRequest()
{
// open session
}
@Override
protected void onEndRequest()
{
// close session
}
};
}
If you use Spring for instance, you could just configure the hibernate
session filter that comes with it instead.

Re: More on Wicket/Hibernate...
It's really very simple. I'm doing the same thing here. You simple use
the HibernateUtil example that is in the Hibernate documentation. Then
you simple create a custom RequestCycle by overriding this method in
your application. With the request cycle you can open and close
Hibernate seesion. Then with a custom RequestCycle you can get it from
anywhere, it uses thread local, and us it to access your database.
Here's some example code:
##
@Override
public RequestCycle newRequestCycle(Request request, Response
response) {
return new RequestCycleImpl(this, request, response);
}
##
public class RequestCycleImpl extends WebRequestCycle {
private Session hibernateSession;
public RequestCycleImpl(Application application, Request request,
Response response) {
super(application, (WebRequest) request, response);
}
@Override
protected void onBeginRequest() {
this.hibernateSession =
HibernateUtil.getSessionFactory().openSession();
}
@Override
protected void onEndRequest() {
if (this.hibernateSession != null) {
this.hibernateSession.close();
}
}
public Session getHibernateSession() {
return hibernateSession;
}
}
##
public class AllDivisionModel extends LoadableDetachableModel {
protected Object load() {
Session session = ((RequestCycleImpl)
RequestCycle.get()).getHibernateSession();
Transaction tx = session.beginTransaction();
try {
@SuppressWarnings(value = unchecked)
ListDivision results = (ListDivision)
session.createCriteria(Division.class)
.addOrder(Order.asc(name))
.list();
tx.commit();
return results;
} catch (Exception e) {
Logger.getLogger(getClass()).error(e);
tx.rollback();
}
return new ArrayList();
}
}
##
private boolean isLoggedIn(String username, String password) {
Session session = ((RequestCycleImpl)
getRequestCycle()).getHibernateSession();
Transaction tx = session.beginTransaction();
try {
SysUser user = (SysUser)
session.createCriteria(SysUser.class)
.add(Restrictions.eq(username, username))
.add(Restrictions.eq(password, password))
.uniqueResult();
if (!user.isLockout()) {
return true;
}
tx.commit();
} catch (Exception e) {
Logger.getLogger(getClass()).error(e);
tx.rollback();
}
return false;
}
##
All that said, I'm pretty new my self, so I'm sure it can be improved.
This seems to work so far for me.

I'm attempting to build a fairly simple web application with Wicket,

other frameworks like Cayenne have been suggested and I'll look at
them too...)
I think I've figured out the basic application structure, and how to
map my data to an html page. But I don't think I understand the
relationships between web sessions, hibernate sessions, DAO objects
etc. I need to open a mysql db, read a set of objects from a table,
and display them in a (paged) table on the screen. I've looked at
several examples but they are using in-memory databases, or Spring
along with Hibernate and I can't get a handle on what needs to be done
to whom and by whom
Anyone have a really simple MySQL example like that? Or an online
tutorial that I could follow?
Much obliged,

Re: A button that does NOT submit form?
Ah, yes. Link-O-Matic. Use the docs, that's what they're there for. Sorry.

Really new, but do you mean use the new Link() and input... ? Like this:
in code:
add(new Link(cancel){...});
in html:
input type=button wicket:id=cancel...
Like that?

Re: RequestCycle?
Probably not. I'll probably use it when I get a chance. I just downloaded the 1.0 tar and saw it's using 1.2 Wicket. Shot me the link and I'll see if I can give it a shot tonight. ChuckDeal wrote: Stanczak Group wrote: I'm not for sure what to use. I tried to override the newRequestCycle() but I had trouble understanding it. I'm doing something like what DataBinder does, but with 1.3. DataBinder seems to be 1.2. Either way I'd rather use my own. Does anyone have an example of providing my own request cycle, or is there an easier way? Sam Hough wrote: I think it is setup with ThreadLocal so you can get it easily with RequestCycle.get(). You can also provide your own version from Application.newRequestCycle which might be more what you need to hook in start/end events.

Databinder also does a pretty good job of integrating Hibernate into the Wicket models. Is there a use case for which Databinder does not work for you?

Adding to response header (filename)?
How can I do this in Wicket? I'm writing a csv generated file to the output, but I don't know how to tell the client what file name to use. This is what I was using before, is there another way? getResponse().setHeader(Content-Disposition, attachment;filename=\export_ + formatFile.format(Calendar.getInstance().getTime()) + .csv\); Code## getResponse().setContentType(text/csv); getResponse().setHeader(Content-Disposition, attachment;filename=\export_ + formatFile.format(Calendar.getInstance().getTime()) + .csv\); OutputStream cout = getResponse().getOutputStream(); cout.write(out.toString().getBytes()); cout.flush(); cout.close(); -- Justin Stanczak Stanczak Group 812-735-3600 All that is necessary for the triumph of evil is that good men do nothing.

This works: getWebRequestCycle().getWebResponse().setContentType(text/csv); getWebRequestCycle().getWebResponse().setHeader(Content-Disposition, attachment;filename=\export_ + formatFile.format(Calendar.getInstance().getTime()) + .csv\); OutputStream cout = getWebRequestCycle().getWebResponse().getOutputStream(); cout.write(out.toString().getBytes()); cout.flush(); cout.close(); But I get this in the logs.

Passing Values Between Pages?
New person question here. I just started using Wicket, but I don't
understand how to pass values to other pages. Can't seem to find
examples. Here's what I setup so far, but it doesn't seem to work. Just
started using Wicket yesterday. Also, how do I put something in a
application wide session. Like a login id?
@Override
protected void onSubmit() {
StudentInformationPage page = new StudentInformationPage();
page.setVisitDate(visitDate);
setResponsePage(page);
}

Using Hibernate in Wicket?
I'm using Hibernate with the HibernateUtil class. It all works except
when I try to use the HibernateUtil in the Application.onDestroy()
method. I want to have it close the factory when the server is shutdown.
It's an embedded database so it's saying the database is locked. This
looks to me like the Application is running in one thread and the Pages
in another. It's like the HibernateUtil static code is running twice.
Is there a better way of using Hibernate in Wicket? Here's the code I'm
using now.
###
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new
Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println(Initial SessionFactory creation failed.
+ ex);
throw new ExceptionInInitializerError(ex);
}...
#Application#
... @Override
protected void onDestroy() {
System.out.println(Killing database connection\n\n);
HibernateUtil.getSessionFactory().close();
}

Re: Using Hibernate in Wicket?
Thanks. They are pretty much doing the same as me. I found it was the
IDE causing the issue. From some reason Tomcat is deploying it twice.
