Hello

I am new to struts and i have a link on one page.The link is like that -:

http://localhost:8080/abc.jsp?id=786

now when i reached abc.jsp , then please tell me that how to retrieve the value of id from the link with the help of any struts tag.
This is the case for URL rewritting.

Thanks

If you use the tag:

<bean:parameter id="id" name="id" />

Struts creates an id variable as a String in page scope. You can then use this variable as you would any other bean, as in:

<bean:write name="id"/>

Now that I've answered your question, I'll mention that a great many Struts developers (myself included) prefer to use JSTL tags over Struts tags whenever either will do the job. JSTL tags are more standard throughout the Java community, and they are more powerful.

<cut value="${param.id}" /> will do the same job a little more elegantly.
