Allow blank fields in JSP form

Hi,
I have a form where you have to enter some information. Some fields are optional. When I try to insert the data in the database, the null fields give me an error. How can i rectify this? I am using
<jsp:setProperty name="userInfoBean" property="*"/>
to set all the properties. Also I am using JSP even for DB access.
Thanks,
Anu

I guess u will definetely have a place where u build the query..there u just check whether a particular field is null...
try{
String something=request.getParameter("form_field_name");
//if the request.getParameter returns null, the catch section is exceuted
catch(){
// set the field as null here..ie. ''
so, when u try to insert the record in the database no error will be thrown.

  • Managing Blank Fields in Search Form

    I am trying to create an advanced search form to filter a recordset of events, so that I can search through these events based on parameters such as category, time, date, place, etc. Right now, because I'm new at this, I have been trying to create a filter with only two parameters, category and price. 'Category' is the first field in the form and 'price' is the second field in the form, followed by fields for time and location. When I search by category, the search works fine. When I search by category and price, only the category parameter works, and it doesn't filter by price. When I search only by price, the recordset comes up as blank. Does this have something to do with fields in the form being left empty or do empty fields have no effect on the search. When I test my query statement on my SQL query browser, it works fine, so I don't think that's the problem. Any help would be appreciated.

    Not an ADDT-specific question so I never responded. However the OP re-posted here in the Dreamweaver Application Development forum which produced a very interesting thread.

  • Infotype 0002 not allowing blank entries in the form of address field

    For Great Britain (GB), Italy (IT)  and Belgium (BE) , the countries I encountered during testing, when I enter a blank in the 'Form of Address' (Salutation) field in IT0002 - Personal Data and try to view after save, it reverts it back to the old value like 'Mr., Ms. etc. I tried the same for U.S. and it works fine and keeps the blank as a valid value.
    There is an old SAP note of 633206 about Belgium but it should have been fixed with later versions (I am on ECC 6.0) - Anyone has any idea why?
    Thanks!

    Thanks guys for looking into it.

  • Access 2013: Sum fields on a form suddenly showing up blank

    I have a simple Access database (originally built in 2010, now running 2013). Sometime in the last week or so all of the SUM fields in the database started showing up BLANK (one minute everything was working fine, the next it wasn't, not sure what happened
    in between). Even when I create a new, basic form, I can't seem to get my SUM fields working.
    For example, I have a table where I document number of miles traveled for work purposes, the fields include: TravelDate, ProjectID, Mileage, and Description. Mileage is a Number field, Long Integer. If I create a continuous form, connect it to the table
    (same thing happens if I connect to a query), add a field in the Detail section with
    Mileage as control source and txtMileage as name and a field in the FORM FOOTER that is: =Sum([txtMileage])...the SUM field is empty in
    Form View. And, there are no NULL values in the data set. This is happening across all of my forms and subforms, all SUM fields are now displaying as blank.
    Is it possible that I changed a global Access setting to cause this? A form setting? Any other ideas?
    Thanks!

    I had the same sudden issue. But I was able to determine that it involved only one workstation. All the others were fine, as well as a test run on another Win 8 station outside the environment. From there I was able to determine that  a third party
    app had been installed near the time of the problem showing up. I uninstalled it and it immediately was resolved. The app was a C# based tool thought the authors have yet to identify why this caused a problem. My suspicion is that they wrote a 32 bit version
    and this was installed on a 64 bit station, and there is some issue with mso.dll, where I believe the function calls exist for sum. I am testing to see if there are similar function errors in Excel.
    What is noticeable was that Access did not throw a an Error# nor a #name. Just nothing appeared, and when you click on a row, the sum would appear, though it was incorrect.
    In Access 2010 I remember there were some footer field issues in continuous which eventually were patched.
    It was an opportunity to remind my client - do not install anything from any one on the live system without prior testing.

  • ODS Key Fields allows blank values in Transformation

    Dear Experts,
    I have two layers:
    1. Datawarehouse layer (purpose is to represent exactly data at the backend)
    2. Consolidation Layer
    Scenario 1:
    In Datawarehouse layer, the fiscal variant is a key field in ODS and I have two other key fields i.e. combine to form a composite key.
    When I load the data from PSA to this ODS, I have a record which contains blank value for the fiscal variant. It successfully loads into the Datawarehouse ODS.
    Sceanrio 2:
    In the consolidation layer, i have 4 key fields out of which fiscal variant is one of them. Now when I load the data from the datawarehouse ods to consolidated ods, it throws an error saying:
    Diagnosis
         An exception fiscvarnt_missing was raised while executin
         module RST_TOBJ_TO_DERIVED_TOBJ .
    System Response
         Processing the corresponding record has been terminated.
    The transformation mapping for the fiscal varaint in both sceanarios is 1:1 mapping with the rule type 'Time Characteristic'.
    My questions is:
    1. Why different behaviour during scenario 1 and sceanario 2
    2. Solution to the above issue
    Thanks
    Jain

    Thanks J.S.
    Yes the format selected in the field for the datasource is 'Internal'.
    When loading the data from R3>PSA>ODSX(Datawarehouse Layer), I have no problems even when the field is blank.
    When loading from ODSX-->ODSY(Consolidated Layer) the empty (blank) field for that records throws error.
    Any ideas?

  • How to "encapsulate" a data from a text field in a JSP form

    Hi. I'm trying to make a user's registration jsp page and I'm not sure how I could get the data from a JSP form from the user and store that into some variable that I could later pass to a query to modify the database. I've been using a JavaBean, but I get null values for all the fields of the jsp page. That's logical, since I cannot find a method that will read the user's input and store that into some variable. In my JavaBean, I have get and set methods that will return a String for each of the form fields such as first name and email. The set method will have in a String as a parameter to set that field value (whichever field it is) to the value of the input parameter, but I don't know if there is a method or a way to read and store the values entered by the user into the jsp form. This is a code snippet of the jsp form:
    <TR><TD>First Name: </TD>
    <TD><INPUT TYPE="TEXT" NAME="fname"
                   VALUE="<%= newUser.getFirstName() %>"></TD></TR>
    Here, the getFirstName() method simply returns the value of a String value related to the user's first name, which is initialized as null in the JavaBean. newUser is the name of the JavaBean that I'm using.
    Any suggestions? Thanks.

    haha...nevermind this question also guys...I found out that I could use the request.getParameter("some_String") method with my JavaBean to read and store data entered by the user in a text field.

  • How to save to PDF form View Responses tab without including blank fields?

    Is there a way to save in PDF form from View Responses withouth including blank fields? More specifically, my form has several fields that have action (Show/hide) depending on the values. Once form is submitted and I am reviewing it from View Response tab, I use "save as PDF" button to save/download my completed form, however when I open it, it shows blank fields as well. Is there a way to somehow specify not to include blanks. If there is no way it would be a nice feature to have. Please let me know.

    No, the PDF is always going to show all fields, the "Show/Hide" does not affect the PDF we generate.
    I will soon post a Form for users to submit feature requests, keep your eyes out for an announcement in the forums for it and you can submit this request.
    Thanks,

  • Fields in PDF form are blank: Another Preview question...

    So I get that filling out a form in Preview can create a problem where the end user cannot see the info in those fields unless they click on them.  But I have some additional questions:
    1. Is just viewing a PDF in Preview without making any changes enough to cause this problem?
    2. Is it only Windows users reporting this problem or are Mac users having it as well (when trying to view it in Acrobat or Reader)?
    Here's why I ask:  We created this form but send it out to clients to fill in and return.  I sometimes view these returned forms in Preview because the info loads faster than it does in Acrobat.   No issues there.  But with one form in particular that we received today, anyone trying to subsequently open the form in Acrobat is having a problem.  It seems to be just this form that is causing the problem.  I'm not sure what the client used to fill it out, but they sent back other forms that don't seem to be a problem, so it seems unlikely this one would have been filled out using a different tool from the others.
    Also it appears that Mac users AND Windows users are having issues seeing the fields in this form properly filled out.  Heretofore, I've only read of Windows users having this problem.
    Any insight would be appreciated -- thanks!

    A form has to be saved in Preview in order for it to be corrupted, not merely opened. What OS is used when opening a corrupted PDF in Reader/Acrobat doesn't matter.

  • Hiding Fields in Adobe Form

    Hi,
    I have some fields in my form that i want to hide. I added in some javascript into the button-click event. When previewing in the Adobe LiveCycle Designer, the fields are hidden successfully,but  when i press F8 button the fields are not able to hide.
    My JavaScript is:
    if(this.rawValue == null)
    this.presence = "hidden";
    Thanks.

    Hi,
    you can use as below,
    below Scripting can be used to ahcive this.
    1. FormCalc Scripting.
    2. JavaScript.
    Combination of both is also allowed in same form.
    Example:
    if( hasValue($) ) then
    StaticText1.presence eq u2018visibleu2019
    Else
    StaticText1.presence eq u2018hiddenu2019
    Endif.

  • From database to jsp form drop downlist

    is there a way to put database values from certain fields in the database,into the dropdown list in my jsp form?
    if there is a way what do they call that method?

    hi,
    First you retrive the fields from database and store those values in a List or any collection.
    after that write the code in jsp as like this..
    <select name="list" >
    <%                    
         for(int i=0;i<dblist.size();i++)
              String listitem = dblist.get(i);
    %>
          <option value="<%=listitem%>">
          <%=listitem%>
    <%             
    %>
    </select>Here dblist is a collection which contains the fields which you retrived from the database

    We currently do this in EXCEL 2007, however we looking at converting it to a PDF Form for distribution to our clients to we can track responses, etc.
    My question is really ery simple ... how do I create the above calculations in a form that I want to distribute??  This possible?? If so how (please bear in mind I'm not a developer

    In re-reading your question, I realized you're using a check box. In that case, you will need to create a custom calculation script using JavaScript.
    Something like:
    // This is a custom calculation script
    (function () {
        // Get the value of the check box
        var v1 = getField("Attending1").value;
        if (v1 !== "Off") {
            var v2 = +getField("Rate1").value;
            var v3 = +getField("Days1").value;
            // Sum the two field values and set the value of this field to the result
            event.value = v2 + v3;
        } else {
            // Blank field if checkbox is unchecked
            event.value = "";
    You'd replace the field names I used with the field names you're using.
    This leaves out checking to see if the corresponding Couse field is filled-in, and you'll have to use a custom Format script if you want the type of formatting you show.

  • How to capture the data from a JSP form

    Hi
    I have a JSP form, My task is to capture the data from a JSP and submit to Data Base. for example I have the field like
    Enter Table name to be created in data base: The table name is to be captured by a servlet and by that table name, table should be created in the data base.

    Get the entered value from the jsp into servlet using request.getParameter("enteredTableName"). it will return the String,pass this table name to execute query using JDBC connection and statement objects.

  • Issue with fill in the blank field and back button.

    I am working in CP4 AS2.  I have create a page of fill in the blank fields to simulate filling in a form.  On the next slide, I show the answers by extracting the variables into text boxes.  I have a back and a next button and instruct the user to review their answers and if incorrect, to select the back button in order to reenter the data.  I have the back button set to jump to the previous slide by number (i've tried previous, last slide, etc...)
    The flash movie freezes when I select the back button.  I think flash is having trouble going back to the fill in the blank fields from the displayed variables.  Any ideas? or work arounds for this.  The idea solution would take them back to the page with the data already in the fields so they could correct the errors only and then return to the review page.
    Thanks
