Pop-up in struts

[Miguel Flecha]

Hi.
I'm trying to open a popup when the user clicks a link. From that link I want to call an action, passing it a parameter and display the results in the pop-up window
Could you help me?
Regards
Miguel

[Miguel Flecha]

I got to open the pop-up correctly, but the content of the popup is not displayed. I get the following exception:

org.apache.jasper.JasperException: Cannot retrieve mapping for action /javascript:window

Do you guys know why?
Thanks
Miguel

??

action /javascript:window

please check config in struts-config.xml , All Corect

[Miguel Flecha]

I think struts-config is correct:

<action path="/verproyecto" type="ibt.struts.action.VerProyectoAction" validate="false">
<forward name="proyecto" path="/popup/proyecto.jsp"/>

[David Solera]

Try this <html:link action="..." target="_blank">My Link </html:link>

Cheers,
David

I would definitely consider whether David's suggestion (regular link which happens to open in a new window) is acceptable. Another way might be to use a plain old HTML link (<a href=...> instead of the Struts <html:link> taglib. The latter would let you use JavaScript's window.open() and specify things like pop-up size, etc.

Or you also can use this (to keep on using struts taglibs ):
<html:link href="javascript:window.open();"> The link </html:link>

Cheers, david

[Lasse Koskela]

Miguel, could you post the tag you originally tried to open the pop-up window? (purely out of interest)

[Miguel Flecha]

I don't have the code here, but I'm using <a href="openWindow(param)">Popup</a>

and I define a function called openWindow that uses window.open(....)

I didn't use the target="_blank" because I want a popup window without menu bar, etc.

The popup is opened perfectly, but the problem comes when the action returns the control to the jsp...

I'll post the complete sentence tomorrow morning
Regards
Miguel

Hi all!

This is the how I open the popup:

<a href="javascript penWindow('<bean:write name="codigo"/>')"><bean:write name="codigo"/></a>

This is the function

<script language="JavaScript">
function openWindow(param) {
var url = "<%=response.encodeURL("/defaultroot/verproyecto.do?codigo=")%>" + param ;
window.open(url,'','width=350,height=350,top=134,left=262,resizable=1,scrollbars=1');
}
</script>

And this is the mapping in the struts-config.xml:

<action path="/verproyecto" type="ibt.struts.action.VerProyectoAction" validate="false">
<forward name="proyecto" path="/popup/proyecto.jsp"/>

I hope you can help me
Thanks a lot
Miguel

[Lasse Koskela]

Ok. And it works as it should. How does the pop-up JSP's source itself look like?

[Miguel Flecha]

It just accesses a bean and writes its properties...

[Lasse Koskela]

And those bean property accesses fail?

[Miguel Flecha]

It doesn't reach that point

[Lasse Koskela]

If this
org.apache.jasper.JasperException: Cannot retrieve mapping for action /javascript:window
is displayed in the pop-up window, I suppose you're trying to use the <html:link> tag with some JavaScript in the attributes?

[Miguel Flecha]

I'm using an <a href="...."> with a javascript inside, but that's the way to do it,isn't it?

Struts Error taglib

[Miguel Flecha]

That doesn't help :-(
The problem is with the forward in the struts-config, as the program enters the action without problems and finds a problem when returning back to the popup jsp
Thanks anyway

So, you should be keep all data to session or application scope for display in popup window, i think m it is one solution to solve this problem.

Looks to me like the problem is in proyecto.jsp. If it's not too long, post it, or at least the parts where you have either an html:form or html:link that references javascript:window

[Miguel Flecha]

I'll post it tomorrow morning, I don't have the code here
thanks

Miguel,
In your struts-config.xml

  
<action path="/verproyecto" type="ibt.struts.action.VerProyectoAction" validate="false">
<forward name="proyecto" path="/popup/proyecto.jsp"/> 

Shouldn't path be "/verproyecto.do"?

[Miguel Flecha]

No. That doesn't matter...
Thanks

[Miguel Flecha]

This is proyecto.jsp:


<%@ page language="java"%>

<%@ taglib uri="struts-bean" prefix="bean"%>
<%@ taglib uri="struts-html" prefix="html"%>
<%@ taglib uri="struts-tiles" prefix="tiles"%>

<html:html>

<head>
<link rel="stylesheet" type="text/css" href="images/estilo.css">
<title><bean:message key="proyecto.title"/></title>
</head>

<body>
<center><h2><bean:message key="proyecto.main"/></h2>
<br/>
<table width="80%">
<tr>
<td align="left"><bean:message key="proyecto.nombre"/></td>
<td align="left"><bean:write name="proyecto" property="nombre"/></td>
</tr>
<tr>
<td align="left"><bean:message key="proyecto.codigo"/></td>
<td align="left"><bean:write name="proyecto" property="codigo"/><td>
</tr>
<tr>
<td align="left"><bean:message key="proyecto.cliente"/></td>
<td align="left"><bean:write name="proyecto" property="cliente"/></td>
</tr>
<tr>
<td align="left"><bean:message key="proyecto.creacion"/></td>
<td align="left"><bean:write name="proyecto" property="creacion"/></td>
</tr>
<tr>
<td align="left"><bean:message key="proyecto.main"/></td>
<td align="left"><logic:equal name="proyecto" property="estado" value="0"><bean:message key="proyecto.inactivo"/></logic:equal>
<logic:equal name="proyecto" property="estado" value="1"><bean:message key="proyecto.activo"/></logic:equal>
</td>
</tr>
</table>
<html:form action="javascript:window.close();">
<html:submit><bean:message key="proyecto.cerrar"/></html:submit>
</html:form>

</center>
</body>
</html:html>

[Surasak Leenapongpanit]

<a href="javascript openWindow('<bean:write name="codigo"/>')"><bean:write name="codigo"/></a>

<bean:write name="codigo" property=???>

What is its perperty?

[Miguel Flecha]

codigo is not a bean, is just a String, but you can access it that way.
In case of having a bean you should use the property attribute.
Thanks anyway
Miguel

[Miguel Flecha]

  <html:form action="javascript:window.close();">
<html:submit><bean:message key="proyecto.cerrar"/></html:submit>
</html:form>

Solved!! That was the problem
Thanks to all

Hi, I am experiencing the same problem and wonder if you could explain how you resolved your problem? I have a similar situation that a popup calls an Action, and then a problem occurs at the time of forward.

fyi, this is the url in the popup:
http://localhost:8019/eSystem/documents/a2506d/viewDoc.do?navigation=viewDoc

and this is in the struts-config.xml:
<action path="/documents/.*/viewDoc"
type="com.es.actions.ViewDocAction"
scope="session"
name="OrderDetailForm"
parameter="navigation">
<forward name="viewMultipleDocs" path="ViewMultipleDocsFrame.jsp" />
</action>

and this is the last line in my action:
return mapping.findForward("viewMultipleDocs");

and I got a system error on the my popup after the above line

thx

andrew

[Junilu Lacar]

Andrew, is the error being displayed in the popup window or in the main window that brings up the popup? If your error is in the popup window, then your issue is different from Miguel's. The problem that he had would have caused an error to occur in the main window that had the link for the popup.

[Miguel Flecha]

Maybe a slash missing??

<forward name="viewMultipleDocs" path="/ViewMultipleDocsFrame.jsp" />

[Andrew Leung]

thx, that's what i found too.

i ended up having to make 2 changes for my application to work.

1) add a leading '/' to the forward path in struts-config.xml

2) the forward target jsp, which is really a simple html frame with src='/myDomain/viewDoc.do', has to be changed to 'viewDoc.do'

to complicate things even more, after applying change#1 alone, my application would work on Tomcat, but instead got a 404 on weblogic. Change#2 is needed for it to work correctly on weblogic.
