Create a new Theme: java.lang.NullPointerException

[Sophie DAHAN]

Hello,

Actually, I have to change the design of a web application. A person had create the interface with the visual web and the library webui-jsf-suntheme.jar. For creating the new theme, I have to create a new jar. I use netbeans 6.1 on Ubuntu 8.04 and the following documentation: http://webdev2.sun.com/woodstock-theme-doc/faces/creating-themes.html.

but when I try to do this I have an exception and I really don't know how to fix it. I don't find a forum for asking help so I decide to write this email.

for creating my new theme I did:
1. check out of the source code of the Woodstock project
2. I created the file archipelTheme.properties in the themes folder with this line :
theme.name=archipelTheme
theme.service-class=ArchipelThemeThemeService
(the rest of the file is the same of the theme-name.properties)
3. I created the clone : ant -Dtheme.name=archipelTheme cloneTheme buildTheme buildJsTheme
4. I modified the color for the element Btn2Hov_mjv4 in the file css/colorAndMedia.css
5. I created the jar files : ant -Dtheme.name=archipelTheme

Now I have to configure my netbeans project for using this new theme:
1. I created the folder WEB-INF/lib and put the file : /woodstock/themes/dist/webui-jsf-archipelTheme.jar
2. I added in the web.xml the lines :

com.sun.webui.theme.THEME_RESOURCES
archipelTheme



com.sun.webui.theme.DEFAULT_THEME
archipelTheme

3. I created the folder classes with the file archipelTheme.properties :
# The "styles" or "classmapper" property BUTTON1, which is
# referenced for primary 'button' components is overridden
# to include additional properties in the "MyBtn1_sun4" selector
# defined in app.css. The "_sun4" is required to ensure that
# the selector uniquely named in the page. It is a convention
# only and is defined by the suntheme version 4 theme.
# BUTTON1=Btn1_sun4 MyBtn1_sun4 BUTTON1_HOVER=Btn1Hov_sun4 MyBtn1Hov_sun4
# This property is a "page level" theme property in that the
# style sheet value of this property will be loaded in every
# page of the application. The file itself must be located
# along the web application's class path.
#
Theme.stylesheet=/arhcipelTheme.css

4. I created the folder classes/nls with the file archipelTheme.js :
It is the same of this file
http://webdev2.sun.com/woodstock-theme-doc/faces/theme/com/sun/webui/jsf/suntheme4_2-080402/javascript_uncompressed/theme/nls/suntheme.js
but the stylesheets change with this:

"stylesheets": {
"Theme.stylesheet" : "/archipelTheme.css"

/** "ie7": "/com/sun/webui/jsf/suntheme4_2-080402/css/ie7.css",
"gecko": "",
"defaultUncompressed": "",
"geckoUncompressed": "",
"ie7Uncompressed": "/com/sun/webui/jsf/suntheme4_2-080402/css_uncompressed/ie7.css",
"master": "/com/sun/webui/jsf/suntheme4_2-080402/css/css_master-all.css",
"safariUncompressed": "/com/sun/webui/jsf/suntheme4_2-080402/css_uncompressed/safari.css",
"masterUncompressed": "/com/sun/webui/jsf/suntheme4_2-080402/css_uncompressed/css_master.css",
"default": "",
"ie6": "/com/sun/webui/jsf/suntheme4_2-080402/css/ie.css",
"safari": "/com/sun/webui/jsf/suntheme4_2-080402/css/safari.css",
"ie6Uncompressed": "/com/sun/webui/jsf/suntheme4_2-080402/css_uncompressed/ie.css" */
},


Now when I running the application I have the following exception:
[#|2008-10-29T13:55:55.259+0100|SEVERE|sun-appserver9.1|javax.enterprise.system.container.web|_ThreadID=21;_ThreadName=httpSSLWorkerThread-8080-2;_RequestID=6f09cfc2-b79a-4746-bdc2-1819b6f71690;|WebModule[/ArchiPEL/Administration]null
