How to implement navigation inside WebTop between JSP pages

vsoman1984

Hi All,

I have customized Documentum to add many of my functionalities.But never used navigation to go from one page to other.

I tried using the approach i have always used of analysis of similar built in options and preparing my customizations on top of them ; but for this case my search has not yet yielded any success.

Here are the steps i ve completed.

1) Placed my custom menu inside menubar.

2) On its click i open up the webtop container belonging to the builtin option"Export to CSV"

So on click of my custom menu item, the following webcontainer opens up.I have modified the jsp pertaining to Export to CSV to add a label and a dropdown box:

My aim is to place a "Next" button on this JSP and on its click navigate onto a diferent JSP say "abc.jsp" in the same container.This "abc.jsp" will detail the selected item in the prev jsp.

My CustomPage.java file has the same contents as ExportToCsv.class and the JSP rendering the image shown above is:

<%
//
%>
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page errorPage="/wdk/errorhandler.jsp" %>
<%@ taglib uri="/WEB-INF/tlds/dmform_1_0.tld" prefix="dmf" %>
<%@ taglib uri="/WEB-INF/tlds/dmformext_1_0.tld" prefix="dmfx" %>
<%@ page import="com.documentum.web.form.Form,
com.documentum.custom.library.FreewayDashboard" %>
<dmf:html>
<dmf:head>
<dmf:webform/>
</dmf:head>
<dmf:body cssclass='contentBackground' topmargin='0' bottommargin='0'
leftmargin='0' rightmargin='0' marginheight='0' marginwidth='0'>
<dmf:form>
<br>
<table  cellspacing=2 cellpadding=2 border=0 width='100%'>
<tr>
<td colspan="2">
<dmf:label nlsid='Select Project Details'/>
</td>
<td class="leftAlignment">
<dmf:dropdownlist name='' value='' tooltipnlsid='MSG_PRIORITY_LABEL'>
<dmf:option value='en-ca' nlsid='MSG_ENG_CAN'/>
<dmf:option value='en-us' nlsid='MSG_ENG_US'/>
<dmf:option value='fr-ca' nlsid='MSG_FRENCH_CAN'/>
<dmf:option value='es-es' nlsid='MSG_SPANISH'/>
</dmf:dropdownlist>
</td>
</tr>
</table>
</table>
</dmf:form>
</dmf:body>
</dmf:html>

Similarly i have configured the action and component for remdering this page.

Could any one help me with respond.redirect functionality to proceed with the same so that i can navigate on to my next page within the same container.

Do feel free to ask for clarifications.Hope u would help.

Thank You

Regards

Define jsp page in your component XML, along side the default "start", for example "streamline" in webtop\webtop\config\mainex_component.xml

In component java class use setComponentPage to change from default "start" to other JSP

Thank You Brian,

These are the steps i carried out confirming to your suggestion:

1) Modified the component xml:

<component id="viewfreewaydashboard"><!-- Component Layout --><pages><start>/custom/classic/dashboard/freewaydashboard.jsp</start><freewaydesc>/custom/classic/dashboard/freewayDashboardPrjtDetails.jsp</freewaydesc></pages>

2) Placed a link inside my "start" jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page errorPage="/wdk/errorhandler.jsp" %>
<%@ taglib uri="/WEB-INF/tlds/dmform_1_0.tld" prefix="dmf" %>
<%@ taglib uri="/WEB-INF/tlds/dmformext_1_0.tld" prefix="dmfx" %>
<%@ page import="com.documentum.web.form.Form,
com.documentum.custom.library.FreewayDashboard" %>
<dmf:html>
<dmf:head>
<dmf:webform/>
</dmf:head>
<dmf:body cssclass='contentBackground' topmargin='0' bottommargin='0'
leftmargin='0' rightmargin='0' marginheight='0' marginwidth='0'>
<dmf:form>
<br>
<table  cellspacing=2 cellpadding=2 border=0 width='100%'>
<tr>
<td colspan="2">
<dmf:label nlsid='Select Project Details'/>
</td>
<td class="leftAlignment">
<dmf:dropdownlist name='' value='' tooltipnlsid='MSG_PRIORITY_LABEL'>
<dmf:option value='en-ca' nlsid='MSG_ENG_CAN'/>
<dmf:option value='en-us' nlsid='MSG_ENG_US'/>
<dmf:option value='fr-ca' nlsid='MSG_FRENCH_CAN'/>
<dmf:option value='es-es' nlsid='MSG_SPANISH'/>
</dmf:dropdownlist></td>
</tr>
</table><dmf:link nlsid ='Link' onclick="onClickToProjectDetails" focus="true"/>
</table>
</dmf:form>
</dmf:body>
</dmf:html>

3) Added the following function to my Java class

public void onClickToProjectDetails(){setComponentPage ("freewaydesc");}

I am in the process of creating a build with these changes which will take a few moments.

Could u tell me if this confirms to the approach u suggested .I will revert back with my findings after i deploy the war.

Thank You once again

Hi ,

I deployed the war.But now i think the issue is with the parameters passed to my action event.

The following was the stacktrace:

Could you guide me as to how the action event function needs to be calledto resolve this wrong number of arguments.
What should be the parameters?

Thank You

vsoman1984

Hi Brian

I resolved the error by going through a similar action event and passing Control control and Arguments args as the parameters to the link action.So my function looked like this:

public

I got the desired result.Hope that this approach is valid

Thank You Brian for guiding me

Looking forward to learn further from you.

Regards.
