Calling JSF page from html page
Hi all,
I'm trying to call a JSF application from a plain HTML form on a different
subdomain (and server). Its a search so I only have 1 input field. I have
include the code below. I need to call the method "performSearch" on the
bean that's associated with my searchResults.jsf page. It renders the page,
but never invokes the method. What do I need in my form to do this?
<script type="text/javascript">
function clearForm(textField) {
textField.value = "";
}
</script>
<div class="searcher">
<p>Search</p>
<form name="frmSearch" action="searchResults.jsf" method="post"
enctype="application/x-www-form-urlencoded">
<input id="searchTerms" name="searchTerms" type="text" value="Search"
onclick="clearForm(this);" class="searchInput" onfocus="clearForm(this);" />
<input id="performSearch" name="performSearch" type="image"
src="images/btn_go.jpg" style="align:right;" class="go_btn" />
</form>
</div>

There's another problem with your approach. You cannot use managed-bean
managed-property to inject a value of a *shorter* scope.
So when you get the current exception fixed I expect you'll then get an
error about "cannot inject reference to value of shorter scope" or similar.
In this case searchBean is of scope "session" but you're trying to
inject a value of scope "request" which just doesn't make sense;
dependency injection only occurs once when the managed bean is created.
If this was allowed, then the searchTerms property would only be set on
the first access to this page, then *not* set on later accesses as the
bean already exists. Rather than permit this confusing behaviour, JSF
implementations are required to throw an exception in this situation.
You can add a tag to the page to force an "init" method to be invoked. I
have a custom "callback" I use for that purpose; someday I'll try to get
around to offering that for sandbox/tomahawk. However a hacky
alternative can be implemented. In this case (invoke a JSF page from the
submit of an HTML page) only the *render* of the JSF page is important, so:
<h:outputText style="display:none" value="#{searchBean.init}"/>
private void init() {
// check request-scope flag to see if already initialised, and
// if so then just return.
//
// set request-scope initialised flag
// look for non-JSF parameters and deal with them
}
public String getInit() {
init();
return null;
}
public void setInit(String s) {
}
Another alternative might be to write a PhaseListener that scans the
request for params of a specific name format, eg "jsf.param.bbbb.pppp"
and for each one found create a ValueBinding for #{bbbb.pppp} then write
the value to it. This looks like a very convenient approach but I'm not
so sure about the security implications; looks a bit like that PHP
feature that is now deprecated for security reasons. A somewhat more
secure approach could be to have a config table of (view-id, param-name,
target-property) for the PhaseListener to work from.

Simon

Re: Calling JSF page from html page
Posted by Andrew Robinson <an...@gmail.com>.
The only two possibilities that I can think of are
1) The constructor of the search bean is throwing an exception
or
2) startIndexDisplay is a Long that is null when first accessed and
therefore cannot be converted to a long.
The EL exception is hiding the real exception (it is usually a lot
further down and sometimes cut off in the printed stack trace). You
may have better luck using a debugger.
Questions:
1) are you using Shale, Seam, Spring or any other code that could
cause errors during bean creation?
2) do you have any code in the search bean constructor?
3) is startIndexDisplay a long or a Long?
Also try:
add a try catch in your setSearchTerms:
public void setSearchTerms(String searchTerms)
{
this.searchTerms = searchTerms;
try
{
performSearch();
}
catch (Throwable error)
{
error.printStackTrace();
throw new FacesException(error);
}
}

Re: Calling JSF page from html page
Posted by Andrew Robinson <an...@gmail.com>.
Your "searchBean.getStartIndexDisplay()" is throwing an exception. Can
you provide the code for that function and the get/setSearchTerms
functions?

Re: Calling JSF page from html page
Posted by Todd Nine <to...@gmail.com>.
Thanks for the help. I've tried something similar
<managed-bean>
<description>
The bean used to submit a search result
</description>
<managed-bean-name>searchBean</managed-bean-name>
<managed-bean-class>
com.purdueefcu.website.bean.SearchBean
</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>searchTerms</property-name>
<property-class>java.lang.String</property-class>
<value>#{param.searchTerms}</value>
</managed-property>
</managed-bean>
And I receive the following error
javax.servlet.ServletException: Cannot get value for expression
'#{searchBean.startIndexDisplay}'
javax.faces.webapp.FacesServlet.service(FacesServlet.java:152)
*root cause*
javax.faces.FacesException: Cannot get value for expression
'#{searchBean.startIndexDisplay}'
org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:422)
org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:234)
org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:384)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:138)
If I use this code in my "setter" to check if the param is available, I'm
able to get the value from the form below. Any ideas?
.
Object terms = FacesContext.getCurrentInstance
().getExternalContext().getRequestParameterMap().get("searchTerms");
if(terms != null){
this.searchTerms = terms.toString();
}
performSearch();
<form name="frmSearch" action="searchResults.jsf" method="get"
enctype="application/x-www-form-urlencoded">
<input id="searchTerms" name="searchTerms" type="text" value="Search"
onclick="clearForm(this);" class="searchInput"
onfocus="clearForm(this);" />
<input id="performSearch" name="performSearch" type="image"
src="images/btn_go.jpg" style="align:right;" class="go_btn" />
</form>

Re: Calling JSF page from html page
Posted by Cagatay Civici <ca...@gmail.com>.
Hi,
<managed-bean>
<managed-bean-name>barcaBean</managed-bean-name>
<managed-bean-class>com.fc.barcelona.BarcaBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>playerId</property-name>
<value>#{param.playerId}</value>
</managed-property>
</managed-bean>
Example:
playerDetail.jsf?playerId=10
So when there is request param called playerId in the request parameter map,
it'll be used automatically to set the playerId property of barcaBean
assuming there are references to barcaBean in the playerDetail.jsf page.

Re: Calling JSF page from html page

Perhaps I should be more clear, my last post didn't make much sense. I've
been using EL (obviously since I have JSF pages), but I'm not sure how to
bind to bean values using simple HTTP named params.

I've never heard of EL before, and I'm having trouble finding it on the

Use use el in your faces-config to bind the request parameters to
managed properties on your managed beans. This won't CALL your code,
but when you retrieve the beans to render your page, the managed
properties should be set for you.

How would one's code be called to manipulate this managed bean when such a
request comes through? Is the only way with a PhaseListener?

Re: Calling JSF page from html page
Using request parameters, you could also create a managed property in a
managed bean in your FacesConfig. Use EL to bind the request property
to your bean. Your bean would then be able to generate the results
needed for the bindings on your page. :) It removes the need to do
anything too fancy...

Re: Calling JSF page from html page
Posted by Andrew Robinson <an...@gmail.com>.
I don't think that this is not the best way of doing this. The
UICommand may not decide to decode the way you think it will. What I
would recommend doing is using request parameters. In an on-load style
method of your page, check for the existence of that request parameter
and execute your method.
Or you can create a custom servlet to do this. See
http://wiki.apache.org/myfaces/InvokingJsfPagesWithStandardUrls
Also, a view will only decode and go through the lifecycle if the view
was already created. In your attempt, there is no view to deserialize
for the page, and thus no decode and then no actions and the submitted
values will be thrown out.
Using a servlet or on-load method I really think is the right way to go.
As for on-load functionality check out JBoss-Seam jsf-comp on-load or
the shale view handler.
