Hi Chris, Misun,
I am going to attempt to answer these both here as there seems to be some
interest in Dojo on AppFuse. First a note of warning: I use Spring MVC, so
all instructions are known to work for Spring MVC only. Time permitting (and
enough interest in the user community) I could look into expanding this into
other web frameworks and writing a tutorial, but this has yet to happen.
These instructions are also not going to be very detailed - they give an
outline as to what needs to be done, and hopefully will be enough to get
your projects working.
To get Dojo to work in AppFuse:
1) Dojo and Scriptaculous do not co-exist happily. By default all AppFuse
pages import the Scriptaculous javascript files. To get around this I had to
modify the default template and created a new include JSP called
javascript.jsp. The latter exists in two flavours: javascript.jsp (the
default scriptaculous stuff - don't want to break existing AppFuse pages!)
and javascript-dojo.jsp which is dojo specific. Those pages that require
dojo widgets declare <meta name="scriptType" content="dojo"/> in their
header, and default.jsp does the following:
<c:set var="scriptType"><decorator:getProperty property="meta.scriptType
"/></c:set>
<c:choose>
<c:when test="${scriptType == 'dojo'}">
<%@ include file="/common/javascript-dojo.jsp" %>
</c:when>
<c:otherwise>
<%@ include file="/common/javascript.jsp" %>
</c:otherwise>
</c:choose>
2) global.js has a window.onload function which uses scriptaculous stuff.
I now have three flavours: global.js, global-scriptaculous.js and global-
dojo.js.
3) Configuring the filter in web.xml. This is the bit that is most Spring
MVC specific. If you want to use another framework you are going to need to
do some adapting.
3.1) First the filter declaration:
<filter>
<filter-name>dojoFilter</filter-name>
<filter-class>org.appfuse.webapp.filter.DojoFilter</filter-class>
<init-param>
<param-name>includes</param-name>
<param-value>*.html,/reports/*</param-value>
</init-param>
<init-param>
<param-name>excludes</param-name>
<param-value>/scripts/dojo/*</param-value>
</init-param>
</filter>
This will include (i.e. send to the dispatcher servlet) everything that
ends .html or starts with /reports/ (I have JasperReports integrated as
well), excluding anything that starts with /scripts/dojo/ (the location in
which I have installed the dojo scripts). I have also left the filter
default for the dispatcher servlet name in place, which fowards to a servlet
called "action". Depending on how the dispatcher servlet is configured in
your web.xml you may need to change this.
3.2) Now the filter mapping:
<filter-mapping>
<filter-name>dojoFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
In my case I have placed this last in the chain.
3.3) Comment out/remove the existing dispatcher servlet URL mapping (the
dojo filter takes full responsibility for fowarding all requests to the
servlet):
<!--<servlet-mapping>-->
<!--<servlet-name>action</servlet-name>-->
<!--<url-pattern>*.html</url-pattern>-->
<!--</servlet-mapping>-->
3.4) I changed the mapping for the hibernate filter so it only gets
applied to requests for active pages:
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<servlet-name>action</servlet-name>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
And that should pretty much do it.
Mike.
