Thanks for the info.
I am setting some value to a hidden field through javascript which can then be used as a flag when the 2nd request goes. Hope this works.

Hi Team,

I have a requirement where a form is present with first name, last name, file upload etc. File upload is done through ajax call and then the form is submitted to a servlet. I want to know whether the file has been uploaded or not in the servlet which is called after i click on the form submit button.
So is there any way i can read the response of the ajax call in the servlet ?

here is the ajax call below

Hello All,

I have a small struts 1 application which when executed using ActionForm runs fine but when i use DynaActionForm or DynaValidatorForm i get an error.
I want to display the values entered in one jsp by user in other jsp.
I am using ${addContactForm.fname} in jsp to retrieve the value entered by user in form addContactForm and field fname, but i get the error :-

javax.servlet.ServletException: org.apache.jasper.JasperException: javax.el.PropertyNotFoundException: Property 'fname' not found on type org.apache.struts.action.DynaActionForm

Various files used are as follows:

web.xml

Hi Joe,

My xml is fine. I see errors when i change the version of ......dtds/validator_1_0_1.dtd">
I am using commons-validator-1.3.1.jar. when i use validator_1_3_0.dtd which is as per the jar file i am using, an error The content of element type "field" must match "(msg|arg|var)*" is shown.
Whereas when i use the validator_1_0_1.dtd no errors are displayed.
So i am not understanding which dtd should be used so that the application runs fine.
Also, even when i am using validator_1_0_1.dtd there are runtime errors as shown below.

INFO: Loading chain catalog from jar:file:/D:/codex/workspace1/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/StrutsLab9/WEB-INF/lib/struts-core-1.3.10.jar!/org/apache/struts/chain/chain-config.xml

Thanks for your help.
