I want to post the values of the form in the same Jsp Page
I want to post the values of the form in the same Jsp page.
Was that a question? Or are you just informing the world of your grand intentions?
But yeah, all you need to do is direct your action to the same page you're in. So, if this is your foo.jsp, it'd be something like...
<%
if(request.getParameter("bar") != null) out.println("Hello");
%>
<form method="post" action="foo.jsp">
<input type="text" name="bar" value="baz">
<input type="submit">
</form>When you submitted your form, it would post the value to the same JSP page as you're already in, and print out Hello to the screen. "Hello" would not print out on the first visit, as the request would obviously not contain the parameter "bar" yet. -

How to submit two forms once in one jsp page?
hello all,
My jsp page includes two forms: one form's action is a File Upload servlet, which process file uploading; another is a general servlet to collect user inputs, such as user name, age, etc.
Because the file upload servlet is a legacy component, and it was used in many applications. we could not meger it into our business components.
the system requires the file upload and information collection are submitted once. so we have to submit two forms in one 'Submit' action, at the same time, the information collection servlet need get the information from file upload servlet, such as the uploaded file's url.
I have tried two methods, but all failed
1. Upload form has no a 'Submit' button, when user click the 'submit' button of the information collection form, we use a javascript to submit upload form first, then submit information collection form. Failed at: the second submit dose wait for upload finishing, then the second submit interrupt the upload
2. the javascript only submit upload form, and set HTML body's onUnload event to another javascript that submit information collection form. this time, the file upload sucess, and information collection form sucess at most time. But fail when user click the 'refresh' or 'back' or any navigator buttons of the browser. these action will trigger the page 'unload' event too, but the submit if invalid!
Please tell me how to.chain the both requests!
- build one mutlitpart request and send it to a servlet that can handle that multipart request (think of using oreilly MultiPartParser).
- check the input (all requiered fields and files there)
- if yes store the user fields and create a socket connection from your servlet to the legacy file upload servlet and post the file this way.
- like this you have full control over the users input and can make sure the file and the fields are just save if all requiered elements are availble. -
Two Identical forms on the same JSP page.???
Hi want to have two identical submit forms on the same form but for some reason a get a javascript error when i add the second form to the JSP page... can you help me...
I assume you meant "two identical submit buttons", instead of "two identical submit forms". Seeing your description of the problem, I believe you can reproduce it with a pure .html page, that is, a page containing not JSP code. So it is not a problem in JSP domain proper.
I was going to direct you to the Technologies>>Internet>>Dynamic Services forum at
http://forums.oracle.com/forums/thread.jsp?forum=95
Then I found you have posted the same question as thread 298169 there. -
How to open a JSP page from a form ??? plz help
hi ..
i want to know how to open a jsp page from a oracle apps form using a button .
the requirement is that whenever we click on the button created on the form, it opens a jsp page.
plz help me ..its urgent !! :-(In portlet project, to navigate between pages, you should not use the URL property to link to a page. Instead, portlets use navigation via action handling. You use the Page Navigation editor to set up links to pages; that is, the navigation editor sets the action property.
Here is an example to hyperlink ans button to open a new page:
# From within the IDE, create a new portlet project. This action creates the project and one page, PortletPage1.jsp.
# Create a second portlet page, called PortletPage2.jsp, for the project.
# Drop a Hyperlink component onto the first portlet page, PortletPage1. (You can drop the Hyperlink on the page in the Design window or on the PortletPage1 node in the Outline window.) Change the Hyperlink's text property to Next Page.
# Drop a Button component (found in the Basic section of the Palette) onto the second portlet page, PortletPage2.
# Open the Page Navigation Editor. It displays the two pages (PortletPage1.jsp and PortletPage2.jsp) of the application.
# Click the PortletPage1.jsp icon in the Navigation window to expand it, and then drag a connector from hyperlink1 to PortletPage2.jsp. Change the name of the connector from case1 to Page2.
# Click the PortletPage2.jsp icon in the Navigation window to expand it, and then drag a connector from button1 to PortletPage1.jsp. Change the name of the connector from case1 to Page1.
# Run and deploy the portlet. The browser displays PortletPage1 and you should see the Next Page hyperlink. When you click the Next Page hyperlink, the Apache Pluto Portal server displays PortletPage2. Click the Page2 button to return to PortletPage1.

Forwarding JSP page through requestdispatcher problem in submiting form
Hello everyone,
I am very much new to servlet.
My problem is somewhat this....
when i am forwarding one JSP page by requestdispather , there is no problem.But after that when i am trying to submit one html form written inside the jsp page , the request is not submiting the jsp page rather it resides in the servlet.
The code in servlet is
RequestDispatcher rd =getServletContext().getRequestDispatcher("/applyConfirm.jsp");
rd.forward(request,response);
Now in (applyConfirm.jsp )jsp page one button is there , so when i will click that button the page has to be submitted.But its not submitting rather the request resides in the servlet.
Dose someone will have any idea.
Thanks in advanceFirst check what sort of button you are using. It should be of "submit" type.
Check the URL to witch URL it is submitting i.e. Action property in <FORM> tag.
Make sure for the URLs in the client i.e HTML ex: href, action, and so on use the thumb rule of prefixing "<%=request.getContextPath()%>/" in your JSP or in servlet add it in the java code.
This should solve the relative URL reference problem.
Hope this helps.
Cheers. -
How to call the form bean value on jsp withthe help of jstl tag
hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstlYou use the jstl core:if or core:choose combined with the EL:

Updating Data in Database using JSP
Hi all,
Can anyone please give me an idea that i have a JSP page that connects to the MS Access database. Now i have a query that shows all the data sorted by date for each individual user. Now if anyone wants to update from there meaning that there should be an update button.And if anyone press that then all the on the particular row will be shown in text boxes and then the user can modify the data. and press update to send the data to the database and show the correct one on that page again.
I know it is a bit hazy. Noe point is i created the query and the update button. Now how can i create text boxes for a particular row if button pressed and also i want to show the dataon this page again dont want to go to another page and do the same thing again. This will enable user to update each row separately on the same page and after all these he can log out. Please help me.
Another question how can i pass some data from an HTML form to the same JSP but in a different place meaning that if i direct the form to the same JSP like "form action=same.jsp" then it will start doing everything from the beginning of the page. But i want to go to a particular form of the same JSP page. Can anyone please help me.
I will be very grateful
Thanks.Can anyone please look at it. Very Urgent. Thanks

Need a fast answer... passing javascript variable to jsp page (how to use)
This test application has 3 frames.
I'm assigning a value "stuff" to a variable ("testfield1") in a javascript function ("getTest") that exists inside an html frame (testpage1.html)
Then, I click on the "test submit" hypertext link to pass the value of "testfield1" to the JSP frame (testpage2.jsp) by invoking a function ("getData") in "testpage2".
In function ("getData"), I am passing the variable "testfield1" as a parameter to the "getData" function in "testpage2".
In "testpage2" - in the ("getData" function) I try to assign the value of the variable "testfield1" to another variable called "testfld1".
Then, I try to extract the value of "testfld1" into a variable called "tstfld1" in a JSP scriptlet
....I.E. [ String tstfld1 = request.getParameter("testfld1"); ]
But, the value is apparently not passed successfully, as tstfield1 appears to be "null".
Can anyone explain what I'm doing incorrectly?
The code for this test app is below...
********testpage0 - the parent frame*********

<%
String tstfld1 = request.getParameter("testfld1");
%>
<P> testfld1 = <%= tstfld1 %> </P>
</body>
</html>parent.frames[2].getData(testfield1); is in testpage1.html
so in the document.pageData.testfld1.value = testfield1; document = testpage1.html( not testpage2.html)
modifying the getData to accept the document object, and refering this object to parent.frames[2].document may help you.

Struts where are values stored between jsp pages?
Hi.I realize that this is forum is not specifically for struts but I thought someone might know the answer to my question.
I have run the following code. The code contains two JSPs that both get there values from the same ArrayList generated by the same actionform so contain the same data. Example.jsp is diplayed when the application is first run when submit is clicked newjsp.jsp is displayed.
If a value in the fields of example.jsp is changed and submit is clicked the altered value is also displayed in newjsp.jsp. I am confused by this as after submit is clicked ExampleForm.java method reset is called which returns the variable values to their original value but the newly entered value is still displayed. Please tell me how this works

}Thanks for responding.
I set the debugger as you suggested and found that method reset is being called.
I did not write the whole of this program I was just playing around with and expanding a struts example I found on line.
http://www.laliluna.de/articles/struts-nested-iteration-tutorial.html
It contains the reset method.
I am interested to know how to reset the values. So am clearing the data after it has been submitted, just to reset. I assumed that once the new page was arrived at the values would be taken from the array.
I am quite new to struts and am not familiar with example_input.action and example.action I will look into these. -
Hi Experts,
I have a login servlet LoginServlet.java and an user welcome screen welcome.jsp. When user login and after user validation i want to open welcome.jsp like
www.wesitename.com/username instead of www.wesitename.com/welcome.jsp. How can i do it please suggest me.
Edited by: live_to_java on Jun 18, 2010 5:29 AMThat's not strange cause You set welcome mapping to "/*" so it also catches your index.jsp. I've modified my code and used filter, here it goes:
