AjaxAnywhere

1. Put the ajaxanywhere-1.2-RC2.jar
in WEB-INF/lib folder. The ajaxanywhere.tld is included in the JAR. The
TLD file tells the JSP/JSF framework where to look for uri http://ajaxanywhere.sourceforge.net/.

2. Modify web.xml, including
following lines in front of filters currently defined in the file:

  <filter>
<filter-name>AjaxAnywhere</filter-name>
<filter-class>org.ajaxanywhere.AAFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>AjaxAnywhere</filter-name>
<url-pattern>*.jsf</url-pattern>
</filter-mapping>

<filter-mapping>
<filter-name>AjaxAnywhere</filter-name>
<url-pattern>*.do</url-pattern> <!-- default Struts mapping -->
</filter-mapping>

<filter-mapping>
<filter-name>AjaxAnywhere</filter-name>
<url-pattern>*.htm</url-pattern> <!-- other framewords mapping-->
</filter-mapping>

3. Download the demo ajaxAnywhereDemo-1.2-RC1.war package. Use jar to
extract the PostingStep1Form.java and put it
in your JSF project

4. Modify the faces-global.xml to include one bean defination:

  <managed-bean>  
<managed-bean-name>postingStep1Form</managed-bean-name>
<managed-bean-class>com.compan.demo.PostingStep1Form</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>

5. On your JSF page, add following lines as highlighted:

<?xml version="1.0"?>
<jsp:root version="2.0"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:aa="http://ajaxanywhere.sourceforge.net/" />

<jsp:directive.page contentType="text/html"/>

... ...
<f:verbatim><![CDATA[

<script src="aa.js"></script>
<script>
ajaxAnywhere.formName="main";
</script>

]]> </f:verbatim>

<h:outputText value="AjaxAnywhere JSF Testing"/>

<aa:zoneJSF id="letterst">
<h:selectOneListbox styleClass="selectListBoxStyle"
size="10"
value="#{postingStep1Form.selectedCategoryId1}"
valueChangeListener="#{postingStep1Form.onSelectCategoryValueChange1}"
id="categoryId1"
onchange="ajaxAnywhere.submitAJAX();"
required="true">
<f:selectItems value="#{postingStep1Form.categorySelectItems1}" id="categorySelectItem1"/>
</h:selectOneListbox>
</aa:zoneJSF>

<aa:zoneJSF id="categoryList">
<h:selectOneListbox styleClass="selectListBoxStyle"
size="10"
value="#{postingStep1Form.selectedCategoryId2}"
id="categoryId2"
disabled="true"
required="false">
<f:selectItems value="#{postingStep1Form.categorySelectItems2}" id="categorySelectItem2"/>
</h:selectOneListbox>
</aa:zoneJSF>

<f:verbatim>
&lt;span id=cnt&gt;0</span&gt; seconds since last page refresh.
<script>
var sec=100;
function counter(){
setTimeout("counter();",1000); document.getElementById("cnt").innerHTML = sec++;
}
counter();
</script>
</f:verbatim>

</jsp:root>


Comments:
The stream of thought is henceforth subjected to a series of transformations which we no longer recognize as normal psychic processes and which give us a surprising http://onet.pl result, viz.. But his face was scarcely as disturbed as his client's, who, in great agitation, had begun to argue with http://fdas.pl him wildly, and was apparently pressing some point against the lawyer's vehement opposal.. I thought perhaps he might want the money for some purpose before he came for http://dupa.pl us.. On arriving at the south gate of the Asylum grounds, I was about to ring, but my friend held my arm and begged me to rap with my stick, which I did.. during sleep, with the subject of the development of anxiety, I could dispense with discussion of the anxiety dream, and thus avoid all obscurities connected with it.. He had made Gideon a national character, a headliner, a star of the first magnitude in the firmament of the vaudeville theater, and all in six short months.. Startling as this admission might have been to any other lawyer, Starbottle was absolutely relieved by it.. She wrenched herself away with an effort, only to be caught again a moment later.. The depreciation of dreams is largely due to the predominance of the indifferent and the worthless in their content.. Please come and take those front suite curtains down to the barn...
