InputJSP - Servlet - Error Message- InputJSP : validation

Hi,
I would like to develop a JSP where the user is allowed to enter the data. I want to validate the input fields in the sevlet controller and may be also connecting to bean in servlet.
How do I get display the error for the user and after that I want to get back to Input JSP for user input.
I would really appreciate any replies for my question.
Thanks,

Why won't you validate the fields by using javascript on the client side before you submit? or if you wanna validate user password then yes you can send the info to servlet, there you connect to database, compare and sendRedirect back to jsp file with everything stored in a session object, then in jsp you check if that session object is null, if not then it means it came from the servlet so now you can fill the fields with the values from that session instead of making the user retype everything. so it's a loop from jsp to servlet and back to jsp in case some field does not match or something.
Good Luck

Error message: "Enter valid currency [Message 173-57]" during Deposit transaction

Hi All,
Is there a specific reason why can't I deposit from a "Multi-currency" cash account to a "specific (i.e., USD)" cash account using the Banking> Deposits> Deposit module.
I have already read below threads related to this issue.

I have posted successfully e cash transfer from multicurrency to monocurrency cash account thru Journal Entry, However, I wanted to know the reason why it is not possible to post this transaction thru the Banking> Deposit module.
Appreciate your feedback on this matter.
Thanks!

Hi,
Same error message is appeared in 8.81 PL10. So this is not due to PL. If you select other than local currency at deposit currency, this error appears.
Let me check and update.

I have OS10.6 and when I try to update I receive error message after validating packages and updates to not tke.

I have OS10.6 and when I try to upload updates I receive an error message when validating the packages. No updates take place.

Are you using Software Update? And what is the error message?
You are on 10.6.0? Why don't you download the combo updater for 10.6.8 directly from Apple and try to install it from there:

Error message - "Overlapping validity areas were found for country BR"

Hi Experts,
For a certain output type Y953 (e.g. for the shipment 2002355665 related to the DN 3087912658), an error message "Overlapping validity areas were found for country BR" is coming in as error.
The error message is appearing during the idoc processing of the shipment.
This is an incident of Dangerous Goods.
I would like to know if it is technically / functionally possible to find out as to why exactly this mesage is coming and how can we rectify the problem.
From technical point of view we checked that this message was not being called in the SAP system but was dynamically called.
kindly let me know of any breakthrough as this issue is critical as dangerous goods are being transported without needed documents printed.
Thanks in advance.

Error message "No valid source context supplied"

Hii,
I will add buttons to my html page. So far, I inserted the following code to my bsp page:
<% DATA: ls_button type CRMT_THTMLB_BUTTON,
                  lt_button type CRMT_THTMLB_BUTTON_t.
                  CLEAR ls_button.
                  ls_button-type = cl_thtmlb_util=>gc_icon_edit.
                  ls_button-on_click = ''.
                  ls_button-enabled = 'X'.
                  ls_button-text = 'Cancel'.
                  append ls_button to lt_button'.
%>
<thtmlb:areaFrameSetter toolbarButtons = "<%= lt_button %>"
                                        maxButtonNumber = "1" />
When I remove the buttons, that I inserted before with the configuration tool (button Coniguration) and test my page, I get the following error message:

Error message on validation script

Hi Guys,
    I created a validation script for MA to check the fill on the extention collection as below.
productColln = doc.getExtensionCollection("PROD_HIER");
productItr= productColln .iterator();
for(member : productItr){
          if(!hasValue(member.get("fieldA"))){
               exception.chainAtEnd(member.createApplicationException("fieldA","Please enter Max Value"));
          if(!hasValue(member.get("fieldB"))){
               exception.chainAtEnd(member.createApplicationException("fieldB","Please enter the Unit Price"));
if(exception.getChain() != null){
    throw exception.getChain();
    1. When the 'fieldA' and 'filedB' are blank, the error message is shown only for 'fieldA'. After i complete 'fieldA' the error message will be shown for 'fieldB'. It seem like it will show only for first one which is put in the chain. I would like the message to show all message in the chain.
    2. When the error message is shown the both fileds are covered by the red line but i would to have the red ' ! ' appear on the tab (ex. for product tab) as well. How can i implement that?
Noppong,
Thank you in advance

Hi Noppong
My understanding is once system gets an exception, it skips to throw statement and the subsequent exceptions, if any ,are skipped. Use of chain exception allows one to write one throw statement in the code rather than multiple throws at various points.
I may be wrong so appreciate if someone can validate this.

How to display an error message after validation in Formatted Search?

Hi SBO experts,
if an error is detected on validation in a Formatted Search, how to display an error message to the user entering the data?
Thanks & Regards,
Raghu Iyer

i created a formatted search query & attached it to the field 'Quantity' at Line Item level in Sales Order screen. just for testing purpose, i eneterd the following code lines in the query validating 'Quantity'
if $[$38.11.0] > 50
begin
select @error = 1
select @error_message = 'Vendor code cannot begin to X sign.'
end
the system throws the error : Internal error (8180) occurred [Message 131-183]
actually, i need to display an error message to the user if Quantity is not in multiples of the OITM.SalFactor2
if $[$38.11.0] % (SELECT T0.[SalFactor2] FROM OITM T0 WHERE T0.[ItemCode] = $[$38.1.0]) > 0
begin
select @error = 1
select @error_message = 'Error in Quantity.'
end
but, this expression to get the remainder itself seems to have some error
$[$38.11.0] % (SELECT T0.[SalFactor2] FROM OITM T0 WHERE T0.[ItemCode] = $[$38.1.0])
i guess, % operator is used for modulo (to find the remainder of one number divided by another.) ? am i right ?

Error message: no valid initialization after client copy

Hi,
We recently did a client copy of our quality BW and R/3 systems from preproduction. In the 'new' clients we have problems with the delta process for 2LIS_13_VDITM. We get an error message that there was no valid initialization in the system, where in fact a valid initialization has taken place (everything from preprodcution was copied).
The source systems setting where corrected using BDLS, but the entries in R/3 tables roosprmsf / roosprmsc were still pointing to the old system. This has now been corrected.
One problem remains. There is no entry for 2LIS_13_VDITM in table RSSDLINIT. I suspect that this causes the error message. Can anybody confirm this ? Is there a standard way to add the correct entry (with the package number of the init package) in table RSSDLINIT or realign table RSSDLINIT with table roosprmsf in R/3 ?
Thanks in advance !

Hi,
After system copy. You will ahve delet your whole data and reload every thing.
In case you are getting dump when you double click infopacakge then delete your data source entry in RSA7 in source system and then go for fresh init load and then continue with delta load. Before goign for fresh init load you will have to first delet the init load entry.
This must help

Retrieving servlet error message on the client

Hi,
I am trying to display a user friendly error message on a swing client after calling a servlet. Unfortunately the only thing I get is the generic 500 error - java.io.IOException: Server returned HTTP response code: 500 for URL: ...
When I call this same servlet from a web browser I get a user friendly exception message.
Servlet code -
ServletException sEXP = new ServletException("user friendly message");
throw sEXP;
Client code -
URLConnection conn = null;
try
url = new URL(targetURL);
// SSL setup omitted
     conn = url.openConnection();
     conn.setDoInput(true);
     conn.setDoOutput(true);
     conn.setUseCaches(false);
     if (conn instanceof HttpURLConnection)
          ((HttpURLConnection) conn).setRequestMethod("GET");
     conn.setRequestProperty("Content-type", "text/html");
     conn.setAllowUserInteraction(true);
     conn.connect(); // Error is thrown here
catch (IOException ioe)
// ioe is now a generic 500 error with the message thrown from the server missing.
Thanks,
Dave

5xx errors means that the server is knackered. So there is no real way for the server to be nice about the errors.
You can try added error pages in to web.xml, but they are less likely to be able to handle 5xx errors.
Normally, a web server (like apache) is placed in front the J2EE web-server to catch this kind of stuff and be nice to the client.

VA01 Error Message - Partners Validation

Hi Experts,
I have written a code to validate the partners(Sold-to & Ship-to) while creating a sales order in VA01 (program 'MV45AFZB') ( user exit form: USEREXIT_CHECK_VBAK).
If an invalid relationship is detected, this enhancement will display an error message and stop the sales order creation until the correct sold-to/ship-to relationship is entered or maintained.
I could able to give the error message based on the validation but the all the fields(Sold-to & Ship-to) on the screen are grayed out and are not ready for input.
Please suggest if there is any way to make these fields input enabled.
We are using SAP version ECC 6.0
Thanks in advance,
Anil

Hi Keshav,
Thanks for your reply. By including the code in SAVE_DOCUMENT_PREPARE of MV45AFZZ I could able to give the error message. Still all the fields are grayed out. and I need to rerun the transaction VA01 with the correct sold-to and ship-to partner data.
Please suggest is there any other way to correct the ship-to data without re running the transaction VA01. After displaying the error I want the Ship-to and sold-to fields should be displayed as input enabled fields.
Thanks,
Anil

Interesting - I got the entire error message in the email, but it doesn't show in your post... I think it's because any indented line is removed and doesn't print in the forum, but it's ok to have in the email.
Yet another anomaly to ponder.
Just saw your revised post - try removing all the indents.

Groovy expression for error message in validation

hi...
using groovy expression i want to display a dynamic error message...(ie.i have a date field the date cant be a past date..if i enter the past date like (02-04-2012 )the error message should display with this date)

For a validation rule on an entity attribute, you can use a Groovy expression to decide whether
an error or a warning message should be displayed using the following expression:
adf.error.raise("THIS_IS_AN_ERROR_MESSAGE")
adf.error.warn("THIS_IS_A_WARNING_MESSAGE")
In your case, you can customize the message and access the date attribute in the message as source.HireDate(Assuming HireDate is the date attribute)
Hope it helps.

Error Message on Validations

HI ALL,
How do we customize item validation error msg? such that my error msg Inline in Notification should look like this:
<label of PX_ITEM1> : Value must be specified
<label of PX_ITEM2> : Numeric value must be specified
<label of PX_ITEM5> : Value must be specified
this way, users may know which items (or fields) was validated with error. this can be done manually for each item validation, but is there a way to create a template for all error messaging with format <label of item> : <error msg> ?
Thanks!
BROKEN.

Broken,
you may take a look at the following links:

They will handle your default errors like field required, number or date picker check already in the browser and also for security reasons again on the server. The raised errors are customizable with a template.
