Thanks Fernando, I was looking for some code like this!

Hi,
Instead using a servlet you could try the following (you can find the
whole
code at wicketstuff pickwick )
This way you will have the session because your are into the
requestCycle
On your WicketApp
mount(new URIRequestTargetUrlCodingStrategy(/upload) {
@Override public IRequestTarget decode(RequestParameters
requestParameters) {
try {
return new
UploadRequestTarget(decodeParameters(requestParameters).getString(uri));
} catch (Exception e) {
throw new WicketRuntimeException(e);
}
}
});
Your own class for uploading images or whatever you want
public class UploadRequestTarget implements IRequestTarget {
String parameters;
public UploadRequestTarget(String parameters) {
this.parameters=uri;
}
public void detach(RequestCycle requestCycle) {}
public void respond(RequestCycle requestCycle) {
HttpServletRequest
request=((WebRequest)requestCycle.getRequest()).getHttpServletRequest();
HttpServletResponse
response=((WebResponse)requestCycle.getResponse()).getHttpServletResponse();
response.setHeader(Connection,close);
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items=null;
PrintWriter out=null;
try {
out = response.getWriter();
items = upload.parseRequest(request);
for (int i = 0; i items.size(); i++) {
DiskFileItem item = (DiskFileItem) items.get(i);
// As we are interested not in regular form fields, we
filter only files
if (!item.isFormField()) {
String fileName=COMPLETE IT
item.write(new File(fileName));
out.print(RESP.100);
out.flush();

hello, I am using MyMultiFileUploadServlet for uploading files and
in
some
wicket component I need find out how many files was uploaded.
I was trying to set this number to the HttpSession in
MyMultiFileUploadServlet and get it in the component:
HttpSession httpSession = ((WebRequest)

String count = httpSession

but count is always null. Is there any way how to get some data from

Re: how to get some data from servlet
Hi all ;
I can't use WicketSessionFilter maybe because I am using Apache Shiro (old
name is Apache Kİ).
In fact Fernando's solution works; Now I can reach and use Session inside
UploadRequestTarget which implements IRequestTarget.
But then I realized that I reach a different Session object in
UploadRequestTarget class. It creates a new Session so i can NOT access it
in other WebPages.
In my Application class;
@Override
public final Session newSession(Request request, Response response)
{
return new MySession(request);
}
Are there any way to access all Sessions or stop creating a new Session in
UploadRequestTarget (which implements IRequestTarget)
Thanks.

Re: how to get some data from servlet
I will post my codes. But now i catched a very very strange position in
WicketSessionFilter . Let me explain :
I used WicketSessionFilter and a Simple UploadServlet as Igor said.
I tested my application using Firefox 3. It gives :
java.lang.IllegalStateException: you can only locate or create sessions in
the context of a request cycle
bla bla bla ...
I tried to debug WicketSessionFilter , I can see that Filter runs and sets
the Session into Thread but then My Servlet doesn't get the Session because
some how WicketSessionFilter 's finally block runs and Session.unset()
method executes.
I think my Servlet can't catch the Session in Thread that
WicketSessionFilter puts or something like that.
The most strange part is : When I tested my application using Internet
Explorer 8, WOOWs , It works. My Upload servlet can reach the same Session
without any exception. I think It means WicketSessionFilter and
UploadServlet runs in proper order.
Also I tested my application in Chrome, and I get the same exception :
java.lang.IllegalStateException: you can only locate or create sessions in
the context of a request cycle
It likes producer and consumer problem.
Sessions in Wicket will kill me :)
Also I set up Wicket examples and I can see WicketSessionFilter runs
properly.
Any suggestions ?
Thank you everybody.

Re: how to get some data from servlet
Hi,
Instead using a servlet you could try the following (you can find the whole
code at wicketstuff pickwick )
This way you will have the session because your are into the
requestCycle
On your WicketApp
mount(new URIRequestTargetUrlCodingStrategy(/upload) {
@Override public IRequestTarget decode(RequestParameters
requestParameters) {
try {
return new

Hi Igor;
I found the problem; problem is when i hit my UploadServlet via http-get
method , i simply write the url and hit the enter then below code is
working
Session wicketSession = Session.get();
I can get wicket Session, wow !! it is great...
BUT ...
When i hit my UploadServlet via http-post method, swfupload access in that
way then i can NOT access wicketSession.
I mean this code :
Session wicketSession = Session.get();
it throws :
java.lang.IllegalStateException: you can only locate or create sessions in
the context of a request cycle
Any idea ?
Thanks

that doesnt make any sense. all things within the webapp share the
session. you guys are welcome to create a quickstart that replicates
this.

Servlet session and Wicket's session are different so you are getting
nul.
Just debug your application and you will see that they have different
session Id's.
I tried to use WicketSessionFilter but it doesn't work.
I am using wicket 1.3.5.

hello, I am using MyMultiFileUploadServlet for uploading files and in
some
wicket component I need find out how many files was uploaded.
I was trying to set this number to the HttpSession in
MyMultiFileUploadServlet and get it in the component:
HttpSession httpSession = ((WebRequest)
getRequest()).getHttpServletRequest()
.getSession();
String count = httpSession
.getAttribute(filesCount);
but count is always null. Is there any way how to get some data from
servlet? Thanks

Hi,
Instead using a servlet you could try the following (you can find the whole
code at wicketstuff pickwick )
This way you will have the session because your are into the
requestCycle
On your WicketApp
mount(new URIRequestTargetUrlCodingStrategy(/upload) {
@Override public IRequestTarget decode(RequestParameters
requestParameters) {
try {
return new
UploadRequestTarget(decodeParameters(requestParameters).getString(uri));
} catch (Exception e) {
throw new WicketRuntimeException(e);
}
}
});
Your own class for uploading images or whatever you want
public class UploadRequestTarget implements IRequestTarget {
String parameters;
public UploadRequestTarget(String parameters) {
this.parameters=uri;
}
public void detach(RequestCycle requestCycle) {}
public void respond(RequestCycle requestCycle) {
HttpServletRequest
request=((WebRequest)requestCycle.getRequest()).getHttpServletRequest();
HttpServletResponse
response=((WebResponse)requestCycle.getResponse()).getHttpServletResponse();
response.setHeader(Connection,close);
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items=null;
PrintWriter out=null;
try {
out = response.getWriter();
items = upload.parseRequest(request);
for (int i = 0; i items.size(); i++) {
DiskFileItem item = (DiskFileItem) items.get(i);
// As we are interested not in regular form fields, we
filter only files
if (!item.isFormField()) {
String fileName=COMPLETE IT
item.write(new File(fileName));
out.print(RESP.100);
out.flush();
}
}
} catch (FileUploadException e1) {
out.print(RESP.200);
// flush the stream to speed up applet notification
out.flush();
e1.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
