How can we represent a matrix like structure in jsf.
Hi ,

How can we represent a matrix like structure in jsf.

It will have x number of rows and y number of columns. Both x and y are dynamic.

so it should be some thing like below .

-------------A B C D . . .

X------------ o o o o . . .

Y------------ o o o o . . .

Z------------ o o o o . . .

.------------ . . . . . . .

.------------ . . . . . . .



1) Using data table we can have columns oriented structure , i mean we can have iterate over any number of rows rendering respective data

but in this case we do not have number of column fixed rather they are dynamic .

Is there any possible solution in jsf for this

This is how we can have iterate over column


<h:column>
<h:dataTable border="1" value="#{nested}" var="item">
<h:column>
<hutputText value="#{nested.rowIndex}" />
</h:column>
<h:column>
<hutputText value="#{item}" />
</h:column>
</h:dataTable>
</h:column>


Thanks in advance

Dymaic SelectOnelist and Onchange event
Hi ,


I made like this check box and below that the list checkbox select event changes the list of cars ...it works .
But now on select of car from list it calls changeCurrentProfile ( ) , valueChangeListener
but for the other list which comes after selecting check box on its select it is Not working ...

I have observed this IF i populate the SelectItem list in bean constructor then only for those items it work if dynamically added some select item on select of check box
these item value should be one value list have in constructor ...for other values added it gives validation error ...i dont have any validation on form


<h:selectBooleanCheckbox id="adminCheckBox" valueChangeListener="#{carProfileAction.changeCarListByType}"> Show Old
<a4j:support event="onclick" reRender="carProfileAction" ></a4j:support>
</h:selectBooleanCheckbox>


<h:selectOneListbox id="carProfileAction" valueChangeListener="#{carProfileAction.changeCurrentProfile}" >
<f:selectItems value="#{adminProfileAction.managersList}"/>
<a4j:support event="onchange" reRender="addNewCarGrid"></a4j:support>
</h:selectOneListbox>





public BeanConstructor()
{
managersList = new ArrayList<SelectItem>();
managersList.add(new SelectItem("car1"));
managersList.add(new SelectItem("Car2"));
managersList.add(new SelectItem("Hi"));
}

public void changeCarListByType(ValueChangeEvent e)
{

if(FALSE.equalsIgnoreCase(e.getNewValue().toString()))
{managersList = new ArrayList<SelectItem>();
managersList.add(new SelectItem("car1"));
managersList.add(new SelectItem("Car2"));
setmanagersList(managersList);
}else{
managersList = new ArrayList<SelectItem>();
managersList.add(new SelectItem("Hi"));
managersList.add(new SelectItem("bye"));
setmanagersList(managersList);
}
}


public void changeCurrentProfile (ValueChangeEvent e)
{

System.out.println("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$:- Select value is :--- "+ e.getNewValue().toString());
}


In this case for onchange event changeCurrentProfile () receives value for car1, car2 and Hi ....... for select of 'bye' it gives validation error .... and no value in changeCurrentProfile (ValueChangeEvent e)

Please can anyone have any input on this issue ?

Thanks ...

<h:selectManyListbox id="list" value="#{optionBean.optionSelected}" >

How to call web service
Thanks for reply ,

You mean in application business logic, when ever need WS I should create new W service instance and get port then create service request object and call it ....
No any pattern needed ...this is going to incise ws and port objects as for i my app i dont have database ....every data will come and go via web service ...


Your second part of http persistance connections aren't heavy ..I guess i dont get ...can you please elaborate on it ?


Thanks

How to call web service
Hey thanks ,

What pattern can be proper in order to call ws in my application with soap bindings .


if i return port object from some class WebServicePort.getTestWsPort(); will that do or if i implement singleton pattern for giving port object will cause some concurrency issue in case multiple classes are using same port.....

basically i m looking for some pattern my web application should have in order to have ws calls.

Thanks
Chetan ...

public class WebServicePort {

private static TestWsService tws;

static {

tws = new TestWsService();
}

public static TestWs getTestWsPort() {

return tws.getTestWsPort();
}

}

3 fiels form based login authentication in Tomcat
Hi


I want Tomcat authentication like company id / username / Password so it looks i should go for Form based authentication ....


1) I wrote login.jsp and error.jsp ;

2)web.xml


<login-config>

<auth-method>FORM</auth-method>

<realm-name>MyFirst Protected Area</realm-name>

<form-login-config>

<form-login-page>/login.jsp<;/form-login-page>

<form-error-page>/error.jsp<;/form-error-page>

</form-login-config>

</login-config>


3 )configured Realm in server.xml of tomcat className="org.apache.catalina.realm.DataSourceRealm";


Now issue is tomcat handles this j_security_check action and i want the j_companyid field in my application ... so how can i get it ....


Can we write an class that will process this authentication and pass insted of let tomcat handel it ?


OR


any configuration that can handel this j_companyid and pass on to application....?


Should we need to write our own Realm if so ....then how to ?


Thanks

Chetan
