Let me see if I understand: You have a jsp file (call it first.jsp) and have <html:link href="/EditShipping.jsp"/> or <a href="/EditShipping.jsp"/> or something the renders an <a href to the EditShipping page. If that's it.. then why would you expect any kind of communication between pages with a link? You would either have to add in the parameters, or use a <html:form tag to post the data in the first page. > > below is my EditShipping.jsp file...Struts config file..and > OrderSummary.jsp > on which the hyperlink is displayed. > ===================================================== > <html:form action="/editShipping"> > <div> > <bean:message key="prompt.FirstName"/> > <html:text property="firstName" size="50"/><br> > > <bean:message key="prompt.LastName"/> > <html:text property="lastName" size="50"/><br> > > <bean:message key="prompt.StreetAddress"/> > <html:text property="address1" size="50"/><br> > > <bean:message key="prompt.Address2"/> > <html:text property="address2" size="50"/><br> > > <bean:message key="prompt.City"/> > <html:text property="city" size="50"/><br> > > <bean:message key="prompt.State"/> > <html:select property="state"> > <html:option value="NY">New York</html:option> > <html:option value="NH">New Hampshire</html:option> > <html:option value="NJ">New Jersey</html:option> > </html:select> > <br> > <bean:message key="prompt.Country"/> > <html:select property="country"> > <html:option value="US">UNITED STATES OF > AMERICA</html:option> > </html:select> > <br> > > <bean:message key="prompt.Zip"/> > <html:text property="zip" size="50"/><br> > > <bean:message key="prompt.PhoneNumber"/> > <html:text property="phone" size="50"/><br> > </div> > ============================================================== > Sruts Config.xml > ======================================= > <action > path="/checkCustomer" > type="com.ecommerce.action.CheckCustomerAction" > name="CheckCustomerForm" > scope="session" > input="/CheckCustomer.jsp"> > <forward name="new" path="/EditShipping.jsp" /> > <forward name="returning" path="/OrderSummary.jsp" /> > </action> > > <action > path="/editShipping" > type="com.ecommerce.action.EditShippingAction" > name="ShippingForm" > scope="session" > input="/EditShipping.jsp"> > <forward name="success" path="/ShippingMethod.jsp" /> > <forward name="failure" path="/EditShipping.jsp" /> > </action> > ===================================================== > OrderSummary.sp > > <html:link page="/editShipping.do"> > <bean:message key="BillingInfo.firstName"/> > </html:link> > ========================================================== > > -----Original Message----- > From: Research labs [mailto:[EMAIL PROTECTED] > Sent: Monday, August 02, 2004 5:17 PM > To: Struts Users Mailing List > Subject: Re: DaTASOURCE CREATION AT USER LOGIN TIME...Newbie > > > Craig, > > Thanks a lot.
