****************************************************************************************** Apologies for Cross Postings ****************************************************************************************** Hello Everyone, I am facing a peculiar problem which I would like to share with the group.. I am trying to do an HTTP "get" to send the form element values to a JSP.I do this using a request.getParameterNames() which returns an Enumeration object.I am trying to read this Enumeration using the enumeration objects nextElement() method into a vector which will be used for further processing based on the data retreived. This form gets filled by a database query and the number of rows that are retreived would vary and are dependent upon the number of rows that match the SQL select query statement.Each row consist of two textboxes which are the parameters that are sent across to the JSP in this case. A typical URL with parameter in this case is something like this http://localhost:4444/xyz.jsp? myselect_sk0=wh&myselect_macro0=weather &myselect_sk1=sp&myselect_macro1=sports &change=CHANGE In this case myselect_sk and myselect_macro are the form element names that are captured using the getParameterNames and values retreived using the getParameterValues which returns a String array.. the problem that I am facing is that if you notice the last parameter that is being passed to the query string is change which in this case has a value CHANGE..This is a submit button which is being sent as a parameter..When I am trying to print the values in the enumeration object it typically prints all the values in the following manner myselect_sk0(first checkbox element in the first row) myselect_sk1(first checkbox element in the second row) myselect_sk2(first checkbox element in the third row) ...........so on change (the button element ) myselect_macro0(second checkbox element in the first row) myselect_macro1(second checkbox element in the second row) myselect_macro2(second checkbox element in the third row) ...........so on If you have a look at the order of the parameter that are being passed they are in the order myselect_sk0=wh&myselect_macro0=weather&myselect_sk1=sp&myselect_macro1=sports&change=CHANGE... ie first checkbox element in the first row,second checkbox element in the first row,first checkbox element in the second row,second checkbox element in the second row and so on........... But on being stored in the enumeration they are getting stored in the way shown above..This is unuusal to me.. I want to avoid the change button value which is getting read in between the two textbox element values as when i read the element values in a loop the loop gets exhausted before the last element is processed..giving me a java.util.NoSuchElementException : HashTable Enumerator Secondly I am running this loop which gets created dynamically based on the no of rows that are retreived. I really have a need to get all the textbox elements alone avoiding the change button parameter.. Could somebody help me out and explain me how is it that the parameters are sent in case of multiple textbox elements in a row of a form.please note ,This problem doesn't arise in case of single textbox as in that case the change button is the last parameter.It can be avoided by doing a Enumeration Object.nextElement() before entering the loop. I would also like to know if there are any limitations of the no of characters that can be sent in a post/get methods..I believe the get method has a limit of 256 chars for it to behave properly ..Correct me if I am wrong.. Hope the problem description is clear enough...Looking forward to responses!! Thanks in Advance!!
