Re: Embedding html from an external application
Actually I haven't used the c:import tag, so i am not sure what problems are you referring to ? Is it what I mentioned earlier that since it would be a separate request, the request-parameters would not be part of it ? but even that can be resolved right ? i mean we can manually stream these incoming request parameters/cookies with the new request.. As for the session sharing issue, I so far have been able to work something out in that regard. Actually its not trivial to move the presentation layer into wicket since (1) its implement in a non-java platform (i.e. mod_plsq) and would not be as simple as moving a jsp (2) it is too huge an app to moved over that easily. Commenting a bit on iFrame. I Initially was more inclined towards using iFrame but then the problem lies with the lag which could be come in between the section loaded through iFrame, which would not look good at all, especially if that section is header/menu/footer, and i am not sure if their is a remedy to this very complain people have from iFrame.

Anyway, the problems you have with this are identical as you would have with the c:import tag. What you want is not simply feasible. It would be wise to consider alternatives. For example moving the JSPs into the same context as the Wicket application, using an iframe (session problem does not go away), or getting rid of the JSPs altogether.

Include uses a URL connection to get the data. You might want to try and
writing a similar component that uses the httpclient library. Or cast the
connection from URL#openConnection to HttpConnection and use the methods
there for adding headers. I think the only major challenge will be if the
old application is using cookies since you'd need to manage them yourself.

Farhan,
You can not mix and match content from different servlet contexts within
the same server. The only way is to request content from another server
and indeed, this is what the c:import tag does. Wicket has no equivalent
component but you could write one without too much problems.
Something like:
public class HttpImport extends WebMarkupContainer {
private String url;
public HttpImport(String id, String url) {
super(id);
this.url = url;
}
@Override
protected void onComponentTagBody(MarkupStream markupStream,
ComponentTag openTag) {
replaceComponentTagBody(markupStream, openTag, getContent(url));
}
private String getContent(String url) {
... code to get data from url ...
}
}
I'll leave the code in getContent as an exercise :)
The component above behaves like a Label, it will replace the content of
the HTML element it is attached to.
Regards,
Erik.

which pretty much is based on the same idea, but the only hitch is that
it
is assuming the external/non-wicket page (i.e. jsp) to be contained in
the
same context/app as wicket. I am looking for a way to include the dynamic
contents from a different context/application, since
RequestDispatcher.include doesn't allow the same. A functionality similar
to
the c:import tag library that is..

Embedding html from an external application
Hi Guys, I am currently investigating on the ways to integrate two UI, one written in wicket and the other in mod_plsql (where all the presentation logic is written in the form of stored-procedures and exposed through mod_plsql gateway). Currently most of the existing functionality is written in mod_plsql and given its a huge application, we cannot port all the of the functionality into wicket in one go (and plan to do the same in phases) but for all the new functionality we have decided use wicket and devise a mechanism to intergrate both the UI(s) such that the header, navigation, footer is embedded from the external mod_plsql app within a Wicket Container/Template Page followed by content-page written in wicket itself. I wish it was easy to move the header/navigation/footer pages into wicket itself, but it has a lot of logic contained within it which just makes difficult to do it now. I have had a look at the blog http://herebebeasties.com/2007-03-01/jsp-and-wicket-sitting-in-a-tree/ http://herebebeasties.com/2007-03-01/jsp-and-wicket-sitting-in-a-tree/ which pretty much is based on the same idea, but the only hitch is that it is assuming the external/non-wicket page (i.e. jsp) to be contained in the same context/app as wicket.
