Customizing Weptop 'Menus' and 'Browsetree'

vsoman1984

Hi All,

Owing to the kind help from the community i have at least got my feet off the ground towards customizations.I got 2 very nice materials on Webtop customizations usng WDK

1) http://developer.documentum.com/developer/Articles/WDK/gtp4_Modifying_Menus.pdf

2) http://customernet.emc.com/developer/Component_Exchange/downloads/HelloWorldWDKComponent.pdf

My aim to customize the Webtop by adding Menu items would have been fulfilled by both these documents.But i sense a missing link in both. After copying the relevant files to the custom area,

Document# 1 on page 13 has the following code snippet:

<dmfx:actionmenuitem dynamic='singleselect' id='file_saveas'name='file_saveas' nlsid='MSG_SAVE_AS' action='saveasxforms'showifinvalid='true'/><dmfx:actionmenuitemdynamic="multiselect"id = "file_rename"name = "file_rename"value = "Rename"action = "rename"/><dmfx:actionmenuitem dynamic='multiselect' name='file_checkin'nlsid='MSG_CHECKIN' action='checkin' showifinvalid='true'/>

My question is where (which JSP) is the above mentioned piece of code written? i searched my Eclipse workspace with the clues for " id='file_saveas' " and "<dmfx:actionmenuitem" from the snippet and could not find it.

Apologies for providing the links as it was the only way i could refer to the documents.Hope i will get the needed guidance

Thank You

Hi,

I would suggest you to take a look at the below documnet ,where step by step procedure is given for customizing menu bar . Navigate to the section "Configuring webtop menu bar" . If the below link is not accessible get the document"Documentum Web Development Kit 6.5 Tutorial .pdf" from powerlink

Home > Support > Technical Documentation and Advisories > Software ~ D ~ Documentation > Documentum T-Z > Web Development Kit (WDK) > 6.5 & Service Packs

http://powerlink.emc.com/km/live1/en_US/Offering_Technical/Technical_Documentation/300-007-232.pdf?mtcs=ZXZlbnRUeXBlPUttQ2xpY2tDb250ZW50RXZlbnQsZG9jdW1lbnRJZD0wOTAxNDA2NjgwMzY5ZDBhLGRvY3VtZW50VHlwZT1wZGYsbmF2ZU5vZGU9MGIwMTQwNjY4MDM2NmU1N19Hcmlk

Best of luck

Hi Balaji

Thanks for your reply.

The development guide does not have the step by step procedure outlined for the task of customizing browsetree.

Could you please guide me with one of my doubts.Can the modigfications only to the "browsetree_component.xml" result in the adding of node to the browsetree node or is there a change to be made to the "browsertree.jsp" as well?

I am referring the "EMC® Documentum® Web Development Kit Version 6.5 Development Guide" is it different from the book you suggested?

Thanks in advance.

Hi,

I always follow the practice of clearing the 'temp' as well as 'work' folders from my Tomcat directory.
To explain in detail, here are the steps i carried out to add a node into the browsertree

Attempt:

1.Serched for browsertree_component.xml and found that webtop/config/browsertree_component.xml internally extends "foldertree:webcomponent/config/navigation/foldertree/foldertree_component.xml"

2.Made my own browsertree_component.xml inside my custom/config with the following content

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<config version='1.0'>
    <scope>
        <component id="browsertree" extends="browsertree:webtop/config/browsertree_component.xml">
        <start>/custom/classic/browsertree/browsertree.jsp</start>

            <nodes>
                <docbasenodes>
                    <node componentid='mytool'>
                        <icon>homecabinet.gif</icon>
                        <label>Freeway</label>

                    </node>
                </docbasenodes>
            </nodes>
        </component>
   </scope>
</config>

This xml extends the webtop/config/..path

3.Copied the browsertree.jsp from "WebContent/webtop/classic/browsertree/browsertree.jsp into my custom folder at location "/custom/classic/browsertree/browsertree.jsp".

I have followed most of the steps from the clues i obtained from the following link

Hi Balaji,

Is Documentum Web Development Kit 6.5 Tutorial .pdf different from Documentum Web Development Kit 6.5 Development Guide .pdf ?

Balaji V S

Yes it has lot of examples on customization.

Kindly mark the thread if the any of the replies are helpfull/correct. This will help others as well.

Looking a the error you get:

INFO: ComponentDispatcher: Component: Exception: java.lang.IllegalStateException: Component Definition mytool 'component[id=mytool]' does not exist within context REQUEST(type=undefined)SESSION(clientenv=webbrowser)APP()

It seems like you do NOT have a component mytool in your Webtop deployment OR this component is faulty and can't be loaded/used

Instead, just to see if your stuff shows up, point your node to an existing component. If it works, then your browsertree configuration is good and you just need to build/fix your mytool component
