Note: be careful with using this method + session bean, as it will work
only once per session, that is the first time bean named qbk will be
used in user session. It may be intended behaviour, but most people need
a to take into account different value for each request.

It shouldn't be big work to create a request bean that does the job of
setting session bean. The same way you set a property of request bean
from #{param.xxx} you can link the request bean to session bean by
setting a managed property in session bean to an EL pointing to session
bean (eg <value>#{someSessionBean}</value>). The most important part is
to ensure the request bean is used upon request by the view. This could
be done by calling a value of request bean.

Re: Myfaces - application calling by link which include parameter
Posted by MPF <ma...@procon.co.at>.
So i try to change my application to a filter:
public class FrontDoorFilter implements Filter {
public void destroy() {
//nothiing to do
}
public void doFilter(ServletRequest req, ServletResponse res, FilterChain
fc)
throws IOException, ServletException {
String oclcNum = req.getParameter(\"oclcNum\");
// did we get a parameter on the request?
if (oclcNum != null) {
HttpServletRequest httpReq = (HttpServletRequest) req;
Curiouser backingBean = (Curiouser) httpReq.getSession().getAttribute(
\"Curiouser\");
// is the backing bean already in the session?
if (backingBean != null) {
// is the backing bean's parameter still unset?
if (backingBean.getOclcNum() == null) {
backingBean.setOclcNum(oclcNum);
}
} else { // create the backing bean and put it in the session
backingBean = new Curiouser();
backingBean.setOclcNum(oclcNum);
httpReq.getSession().setAttribute(\"Curiouser\", backingBean);
}
}
fc.doFilter(req, res);
}
public void init(FilterConfig arg0) throws ServletException {
//nothing to do
}
}
at first the line:
String oclcNum = req.getParameter(\"oclcNum\");
has a syntax error (the first \)
furthermore how i use this filter (add to web.xml and how i call it?)

Hi,
to apply request parameter to managed bean the scope must be request afaik.

Hi!
Well I tried this (but its sound like easy and thats all I need), but the
parameter value is always null!
try to call with following url:
http://localhost:8080/GatheringPlace/jsp/placeDetail.jsf?dbk=1212
my code:
bean:
public class PlaceDetailController {
private String dbk;
public PlaceDetailController() {
// nothing to do
}
public String getDbk() {
return this.dbk;
}
public void setDbk(final String dbk) {
this.dbk = dbk;
}
}
faces config:
...
<managed-bean>
<managed-bean-name>placeDetail</managed-bean-name>
<managed-bean-class>at.pcd.wam.technologie.controller.PlaceDetailController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>

Re: Myfaces - application calling by link which include parameter
Posted by David Delbecq <de...@oma.be>.
Easy way to do it without much complicate front-end code is to use a
bean setter to do the initialization job (assuming all you need is the
common data initialization case):
request:
http://server/webapp/something.faces?xyz=abc
faces-config.xml:
<faces-config>
..........
<managed-bean>
<managed-bean-name>somebean</managed-bean-name>
<managed-bean-class>
com.company.Bean
</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>initialRequest</property-name>
<value>#{params.xyz}</value>
</managed-property>
..........
JSF will automatically evaluate #{params.xyz} upon bean instantiation.
