Hello World component problem

Alpa

Hi Experts,

I have configured webtop on tomcat and trying the Hello Webtop WDK tutorials.

I configured the menu bar and hello world action and till then the webtop was running fine.

If I try to configure the hello world component , webtop starts giving the following error :

HTTP Status 404 - /webtop/

type Status report

message /webtop/

description The requested resource (/webtop/) is not available.

The localhost.logs on tomcat are as follows :

as you can see in error trace:

org.xml.sax.SAXParseException: Invalid encoding name "ISO88591".

So, change this:

<?xml version="1.0" encoding="ISO88591" standalone="no"?>

to:

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

I could onloy perform the first two steps :

1) Configuring the menu bar(helloworld_menu_configuration.xml)

<scope>

<menuconfig

modifies=

"menubar_tools_menu:webcomponent/config/library/menubar/menubar_component.xml"

<insert path="menu[name=tools_menu]"

<actionmenuitem

dynamic = "genericnoselect"

name = "hello_world_menu_item"

id = "hello_world_menu_item"

value = "Hello World"

action = "hello_world_action"

showifinvalid = "true"

</insert>

</menuconfig>

</scope>

</config>

2)Configuring Hello World action (hello_world_action.xml)

<scope>

<component>hello_world_component</component>

<container>dialogcontainer</container>

</execution>

</action>

</scope>

</config>

The webtops run fine and show the added menuitem.

when i try to configure the component (hello_world_component.xml)

<?xml version="1.0" encoding="ISO88591"

standalone="no"?>

<scope>

<pages>

<start>/custom/hello_world/hello_world.jsp</start>

</pages>

<class>com.mycompany.custom.HelloWebtop</class>

</component>

</scope>

</config>

The webtop starts working and gives the error mentioned in my first post.

Please suggest...
