Pop-up windows and struts

This one is hard - for me! ;-)

In a struts-jsp application, is it possible to work with pop-up windows in this way (just an example):

In a calendar-userinterface you click on a date. A small "date-schedule-window" pops up, and you can change your schedule for that day in that window. On the same time, you can continue to navigate around in the original window. - So you can actually wait as long as you like before you alter the date-schedule, save it and then exit. Is this possible?? Yes?!? How??

This f...s up my mind completely, - normally with struts you navigate around between jsp's and Actionclasses, - but suddenly here the session gets "divided".

Any suggesitions?

Regards,

Nic

Yes!

>> How??
Just use another action class and another set of jsp page for popup winodw.

session never gets divided, but rather the control flow is divided and that's OK.

Let me know if you have more specific question on this.

OH, this is interesting!

>>Let me know if you have more specific question on this.

OK:

Imagine this jsp (example!!):

<A HREF=date.do;jsessionid=<%=request.getSession().getId()%>?date=03041975>04/03/1975></A>

<FORM ACTION=scroll.do;jsessionid=<%=request.getSessoin().getId()%>
<input type="submit" value="scroll">
</FORM>

The link should bring you to the mentioned date-page, and the submit-button just illustrates "something else" you want to to do on the calendar page.
My question is then: How should the link look to make it a (small) pop-up sharing the same session?

Thanks,

Nic

P.S. The reason why I dont use tags to create the link is, that very often in my applications links have to be constructed from Java-generated HTML.

first of all, you should never be encoding you own session url, it might work on one type of server, but not the other. the right approach is to use response.encodeURL().

there is a number of ways to popup a new windows, for example you can use target attribute of html <a> tag. If you want to control the size and style of the popup windows, you can use javascript.

Here is an simple raw example of how this should be done:
<A TARGET=calendar HREF='<%=response.encodeURL( "date.do?date=03041975" )%>' >04/03/1975></A>

A struts specific example:
<html:link target="calendar" action="actionName" paramId="date" paramName="yourbean", paramProperty="property">xxxx</html:link>
detail: http://jakarta.apache.org/struts/userGuide/struts-html.html#link

A JSTL example:
<c:url="date.do" var="myUrl">
      <c:param name="date" value="03041975"/>
</c:url>
<a target='calendar' href='<c:out value="${myUrl}"/>'>xxx</a>
