Error when trying setup the practice component webapp

Hi list,

I've downloaded binary
ofbiz-rel4.0-current.zip<http://build.hotwaxmedia.com/builds40/ofbiz-rel4.0-current.zip>,
and I am trying to deploy first "practice" component webapp by following
instruction on:
http://docs.ofbiz.org/display/OFBIZ/OFBiz+Beginner%27s+Development+Guide+Using+Practice+Application

I have hit few problems under "Create the web app":

1) Step4 said copy existing component e.g. example component web.xml, there
is no "example component", but I found
framework/example/webapp/example/WEB-INF/web.xml. With this, there is no "
mainDecoratorLocation" found. (I found this value from
application/product/webapp/catalog/WEB-INF/web.xml though, so I use this)

2) Same thing with "widget" and "error" directory as above and I just copied
from the same "catalog" component.

3) Step 10, after the server is started, I get an error:
org.ofbiz.webapp.view.ViewHandlerException: Unknown handler type: screen

The documentation says I should see the "This is first practice" instead.
Any idea?

Thanks,
Zemian

Re: Error when trying setup the practice component webapp

The tutorial is based on the *trunk* version of OFBiz, not Release 4.
Try downloading and installing the latest trunk distribution.

Re: Error when trying setup the practice component webapp

I tried with the trunk[1] version and still get the same error:
org.ofbiz.webapp.view.ViewHandlerException:
Unknown handler type: screen

[1]http://build.hotwaxmedia.com/builds/ofbiz-trunk-current.zip

What did I missed?

Re: Error when trying setup the practice component webapp

In reply to this post by Zemian Deng

Hi Zemian,
You have to just add the following contents in your
widget->PracticeScreens.xml file.

<?xml version="1.0" encoding="UTF-8"?>

<screens xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/widget-screen.xsd">

<screen name="main">
<section>
<widgets>
<label text="This is first practice"/>
</widgets>
</section>
</screen>
</screens>

So that you can see "This is first practice" rather including everything from the catalog->widget directory...
and just change the *mainDecoratorLocation context param to* "component://practice/widget/PracticeScreens.xml" in your web.xml.

Please read the documentation carefully.

Re: Error when trying setup the practice component webapp

Zemian,
For "org.ofbiz.webapp.view.ViewHandlerException: " you need
to add the following in your controller.xml.
<handler name="screenxml" type="view"
class="org.ofbiz.widget.screen.ScreenXmlViewHandler"/>

and you may take contents of the error.jsp file from any of the
existing ones.

Re: Error when trying setup the practice component webapp

you do not need to add the handler or deal with the error.jsp
Please read the comments in
http://docs.ofbiz.org/display/OFBIZ/OFBiz+Beginner%27s+Development+Guide+Using+Practice+Application
and read the Common_controller.xml
