Re: how to get productID from the url into action class.
Um... What exactly are you trying to do here? Do you just need the
product id from the url string, or are you trying to fetch something
from a different backend? If you just need it from the string, just
use indexOf and substring.

Re: how to get productID from the url into action class.
Hi Prashant,
I have to confess that you have cheered up my morning :) That is quite an
amusing code snippet.
Not sure what you are actually trying to do, but what you are doing is opening
a URL connection to the Showprodsuppliers from within its execute method. So,
naturally, you have created an infinite loop. Can you come back to the list
with a more detailed explanation of you aims?

Re: how to get productID from the url into action class.
Hi Nils,
Please pardon me if I am appearing silly but I 've been trying to get the
productID from the jsp to the action class for 3 days without any luck.
I have got out list of products from the database and I have displayed them on
a jsp using struts 2 tags .
Now what I want to do is to have a all the products appear as hyperlinks so
that when I click on the products its going to show all the suppliers
associated with the products. So i've tried to create a code as follows:
s:iterator value=productDetail
trtda href=showprodsuppliers.action?productID=s:property
value=productID/
s:property value=productName/
/a/td/tr
/s:iterator
the action showprodsuppliers is mapped to the action class I have posted in the
last email.
this is generating a url as follows:
http://localhost:8080/Astralpharma1/astralpharma/astralpharma/showprodsuppliers.action?productID=1
I just need to retrieve the productID from the url. thats it
Please let me know how so I do that in Struts 2

Um... What exactly are you trying to do here? Do you just need the
product id from the url string, or are you trying to fetch something
from a different backend? If you just need it from the string, just
use indexOf and substring.

Re: how to get productID from the url into action class.
I think the mailing list is messing with the order of messages
However,
Documentation and code snippets can be found here:
http://struts.apache.org/2.1.6/docs/bootstrap.html
Basically, map your action in struts.xml, add the appropriate
getter/setter in your action, and it should automagically be set from
the url to your action. If that doesn't work, then there's something
wrong with your setup.

Re: how to get productID from the url into action class.
In the forum entry user David Newton told you to Remove line 28.
Did you do as he suggested? You didn't respond to his suggestion.
What he was trying to explain is that Struts should call setProductId() for you
so that you have no need to mess about with Request parameters, etc.
If you are determined to extract the productId value from the Request URL, then
have a look at this method:
http://java.sun.com/javaee/5/docs/api/javax/servlet/http/HttpServletRequest.html#getQueryString()
But there should be no need for it.

Re: how to get productID from the url into action class.
Obviously, something must be wrong if something as simple as setting
an action property doesn't work. Are you sure that the url to the
action is generated correctly? Try using the s:url tag instead of
assembling the url and parameter by hand. Also, you have not showed
your struts.xml.
I suggest you start again from the beginning, remove everything, just
leave a simple action with the execute method, the getter and the
setter for the property, nothing else. Then get that to work. You can
also use the bootstrap tutorials as a starting point.

If you take a step back, and remove what you have tried to do now,
what did you try, and what didn't work?

Hi Nils,
Please pardon me if I am appearing silly but I 've been trying to get the
productID from the jsp to the action class for 3 days without any luck.
I have got out list of products from the database and I have displayed them
on a jsp using struts 2 tags .
Now what I want to do is to have a all the products appear as hyperlinks so
that when I click on the products its going to show all the suppliers
associated with the products. So i've tried to create a code as follows:
s:iterator value=productDetail
trtda href=showprodsuppliers.action?productID=s:property
value=productID/
s:property value=productName/
/a/td/tr
/s:iterator
the action showprodsuppliers is mapped to the action class I have posted in
the last email.
this is generating a url as follows:
http://localhost:8080/Astralpharma1/astralpharma/astralpharma/showprodsuppliers.action?productID=1
I just need to retrieve the productID from the url. thats it
Please let me know how so I do that in Struts 2
Thanks

When I think of it, that doesn't make any sense either... Isn't the
product id set as a property on your action?

Re: how to get productID from the url into action class.
Hi Nils,
You bet that I did remove line 28.
How ever I have a little doubt about how the population of the private
variables declared takes place.
I am posting my earlier example for your reference.
If you see this example. I got the values from the resultset and stored them in
an arryalist.
then by uisng the populate() method I got the values of productID and
productName.
First of all is this the right way to do things.
Then when I populated my jsp in form of a hyperlink the problem started. The
productID just would not populate.
So my ultimate question is what is the exact way of populating a variable in an
action class.

Prashant

In the forum entry user David Newton told you to Remove line 28.
Did you do as he suggested? You didn't respond to his suggestion.
What he was trying to explain is that Struts should call setProductId() for you
so that you have no need to mess about with Request parameters, etc.
If you are determined to extract the productId value from the Request URL, then
have a look at this method:
http://java.sun.com/javaee/5/docs/api/javax/servlet/http/HttpServletRequest.html#getQueryString()
But there should be no need for it.

Obviously, something must be wrong if something as simple as setting
an action property doesn't work. Are you sure that the url to the
action is generated correctly? Try using the s:url tag instead of
assembling the url and parameter by hand. Also, you have not showed
your struts.xml.
I suggest you start again from the beginning, remove everything, just
leave a simple action with the execute method, the getter and the
setter for the property, nothing else. Then get that to work. You can
also use the bootstrap tutorials as a starting point.

Because you have a public setProductID(), and your request has a
productID parameter. That's how S2 works.
So my ultimate question is what is the exact way of populating a variable in an
action class.
The way I, and everybody else, has been telling you:
public class Productdisplay extends ActionSupport {
public String productID;
public void setProductID(String productID) {
this.productID = productID;
}
}
If your request has a productID and you have things configured correctly
it will be set in your action by S2.
