Any new ideas, i'm still stuck with it
i have to use this logic, couldn't find a replacment

You're dealing with JSF in the same concept of JSP, which loses the power of jsf.
in such scenarios you can follow the next:

you can have only one managed bean, session scoped if for more than one-page process.
you managed bean can be like the next:
public class ProductBean { Product product; @PostConstruct public void init() { product = new Product(); } //getter and setters public String saveProduct() { //from a model class that has a saving method for product new ProductDAO().save(product); } }

now in createProduct.jsp
<!-- for example you have properties name and size in your product object --> <h:inputText id="productname" value="#{ProductBean.product.name}" /> <h:inputText id="productsize" value="#{ProductBean.product.size}" />

so in page viewProduct.jsp simply you can have the next:
<h:outputText value="#{ProductBean.product.name}" /> <h:outputText value="#{ProductBean.product.size}" />

as long as your managed bean is on session scope that would work perfectly.
the code is applied with jsf 1.2.

thanks Tim for the reply, but that wouldn't work, it's throwing NumberFormatException '-' !!??
any idea why ?

Hi vishnu,
I'm having the exact same problem, and am stuck into it, probably if you can please assist me with the way
you solved your problem, or any way you managed achieving that.
Hope some one else, might have an answer also.
Thanks..

Check this link, nice one..
http://java.sun.com/developer/EJTechTips/2004/tt0923.html

Example:
I have 5 JSF components in my page. On some action...I need to set some properties of those components from the backing bean.

now...if I am doing with the scope request and using binding...i can set all the properties of all the components of that page.

or...with session scope and without binding i can do the same.

which one is the better approach?

Is it good idea to keep all the states of all components stored in session??? or bindind could be the good alternative???

Using backing bean can sometimes be abused and mix the business data with the form components, but it has its uses like it is sometimes
necessary for event handlers or validators to have access to the actual components on a form. That case, yes backing beans can be used, but
in general try to use a different beans for business objects.

D is the right answer, simply you can think of JSF as "Swing for server-side applications."

Okay my friend,,
If your page is just like that, you don't have to do that
"replace" technique (this one you use only when you're saving to DB, because
Database quires won't work with single quotes.
but in your case, you went wrong in this line.

<option value='<%=str%>'><%=str%></option>

just change the single quotes for the value to double ones, like this:

<option value="<%=str%>"><%=str%></option>

and later on if you needed to save this name to DB, you change it in the servlet that is receiving the request from this jsp page..
Got it...?

JSF has (ValueChangeListener) which is a listener that is notified of value
changes of radio buttons, check boxes, select item,etc...
Anyway that's JSF, according to JSP, I'm thinking of a way..
I'll get back to you in case of updates..

Note: if you know JSF or want to use this way I can provide you with a snippet.

sorry for my mistake, the code in quote should be like this:
<form action="ProfileEditor?source=<%=request.getParameter("source")%>" ...>

@ William.. there are many ways to reach the page. Your method would involve doing this for all the links to that page. this is something that, though possible, im looking to avoid. Is there a way to check the request parameter? If so what method should i use?

[ February 18, 2008: Message edited by: Sarathy Srinivas ]

here is some code that I've applied in one of my applications,
you'll see the important parts of it:

link in page1.jsp
<a href="/editprofile.jsp?source=page1">Edit Your Profile</a>

link in page2.jsp
<a href="/editprofile.jsp?source=page2">Edit Your Profile</a>

and so forth..

in page editProfile.jsp
<form action="ProfileEditor" ....>

in servlet ProfileEditor inside doPost(request, response)
// the process you want // and now the navigation part at the end String dispatchURL=""; source = request.getParameter("source"); if( source.equals("page1") ) dispatchURL="/page1.jsp"; else if( source.equals("page2") ) dispatchURL="/page2.jsp"; RequestDispatcher rd = getServletContext().getRequestDispatcher(dispatchURL); rd.forward(request,response);

Honestly speaking, I don't know if it's a professional way to deal
with such trick, but this is only what I did to solve it that time..
hope it helps...

i have tried your code, but it is not working.
have you tried ?

Yes, I tried the second one, and it's working with oracle DB.
str = str.replace("\'","\'\'");

You can use this:
String str="Father's Name" str = str.replace('\'','\'\'');
it will work..

sorry, for my typing mistake.. it should be..
[CODE]
str = str.replace("\'","\'\'");
[CODE]
instead of
[CODE]
str = str.replace('\'','\'\'');
[CODE]
notice the double quotes("") in the replace parameters.
