Detecting validation error on client side

If there is some error in validation on the field of ViewObject which is binded with a page, that component shows error message. I want to set some javascript fields on client side when a component gets error. How i can do that?

Hi,
for this you will need to catch the error in a custom error handler and call JavaScript from a managed bean (see chapter 5 of the Web Developer guide in the OTN documentation for JDeveloper and ADF).

"ORA-03113: end-of-file on communication channel error" in client side

Problem Description: we have a production server that oracle 11gr2 installed and oracle clients (application servers) with 11gr2 clients. Sometimes we encounter internal server error 500 at the application server side; and when we check out the application server logs we see ORA-03113 error code.
when we look at the corresponding error on the Oracle Database Server side we saw the following output in the alert_orcl.log :
Fatal NI connect error 12170.

what could be the problem or how can i trace it in order to determine the exact problem? is there any parameter that i need to adjust in client side to ensure that every connection reaches the production server ?

There is often an ORA-0600 or ORA-7445 behind these.
These should produce an entry in the alert log and an associated trace file which a) can be used in the ORA-600/7445 lookup tool on Metalink and also uploaded to Oracle Support.

A bit quick to answer - I didn't see the large section of TNS information from the alert log.

Detecting validation errors

Hi,
how can I detect a validation error?
For example, I'd like to show a generic message at the top of a page which says:
"Some errors are detected, please check your data"
This message is not bounded to a particular field, in fact I can use the <h:message for=""/> tags for showing the errors generated by each field.
The only one solution I found is adding ugly code to my JSP:
<% if (javax.faces.context.FacesContext.getCurrentInstance().getMessages().hasNext()) { %>
<span style="color: red;">Some errors are detected, please check your data</span>
<%}The only one way to detect a validation error is cheking the message queue. If it's empty, no validation errors occured.
I don't like it.
Some help?

I would like to share the kind of approach I had used with the same situation.
You can put one "h:outputText" at the top of the page for displaying all the error messages.Obviously attach it to some backing bean property.
Now whenever you encounter any error just assign your customize message to this bean propery.
Whenever the response is rendered you can see your error message being displayed at the top of the page.
Funny ! but it works !!!!

ERROR IN CLIENT SIDE AFTER PUBLISHING

HI,
javax.servlet.ServletException: olam18.main._start.class not found
I GET THE ABOVE WHEN I TRY TO GET INTO THE APPLICATION FROM CLIENT SIDE WHICH I PUBLISHED SUCCESSFULLY...PLZ HELP ME OUT...

I know this question is two months old, but we had the exact same issue so I wanted to share our solution. This error is actually caused by the tightened security added by Java 6 Update 24. This update made it so that you can't use web.show_document to display local content in a web browser.
Our solution was to use webutil and have the operating system open the local files. Here's what we used:
webutil_host.nonblocking('rundll32 url.dll,FileProtocolHandler '||i_url);
If you pass in a .XLS path, it opens Excel; if you pass in a .PDF path, it opens Acrobat; etc.
HTH,
Brian
PS - One more disclaimer: we did this in Forms 10.1.2.3 and have not fully tested it in Forms 11.1.2 yet.
PPS - Since you're using 64-bit Java, you'll need 64-bit webutil, which is only in Forms 11gR2 (11.1.2).

Validating data in client side

Hi,
I'm developing a web application using Struts framework.
and my questions is, does the validate method int the ActionForm replaces the using javascript validation?
If I can do all the validations in this validate method, so does that mean that i'm not going to use JS at all?

Client side validation is usually a subset of the validation done on the server side (ie, server side duplicates the client side validation, and then some).
I usually only do some basic client side validation such as:
a textfield is null, but shouldn't be
a textfield should be in this format but isn't: mm/dd/yyyy
a textfield should be a number but contains a letter.
If these conditions occur, dont submit the form, pop up a warning dialog box instead.

Error at Client Side

Hi Experts
             My problem is that after developing model deploying when trying to run in EP at client side geting error as
               " Visual Composer FlexiviewsrequireAdobe Flash 7.0 for proper viewing.It Seems your browser does not have appropriate version installed." in internet explorer
           I am making use of VC 7.0 & EP 7.0 And had Flash and SVG Viewer. Can any one suggest me why we are getting this error at run time.
Regards
Ashwin

Hi Ashwin,
for VC7 EP7 you should use Internet Explorer 6 with the latest flash plugin.

If you deploy the model, you deploy it to portal. What do you mean with portal url and which errors?

Yes, you need on your machine IE6 with the latest falsh plugin (and for developing you need MSXML parser 4 and the adobe svg viewer 3).

Detecting validation errors during accept processing

I have a page with the following accept processing components
1. Process - On Submit - Before computations and validations
2. A validation
3. Process - On Submit - After computations and validations
When the page is first submitted, (1) runs fine. (2) runs and the validation fails so (3) doesn't run.
Now when I re-submit the page, I would like (1) to NOT run.
Is there a way to detect that the page is being re-submitted as a result of validation errors and hence suppress certain after-submit components from executing?
[As far as I know, the "Inline validation errors" declarative condition and the g_inline_validation_error_cnt variable only apply during the page rendering phase, so they can't be used here]
Thanks

Hello Vikas,
In version 3.0 you can use a hidden item as a flag, and set this flag with a on load procedure (and NOT computation). The first procedure will be conditioned by "Inline Validation Errors Displayed" and the second one with "NO Inline Validation Errors Displayed". Then you can condition your after submit processes with this flag.
>>As far as I know, the "Inline validation errors" declarative condition and the g_inline_validation_error_cnt variable only apply during the page rendering phase, so they can't be used here
A little test on my local instance confirm this.

FA/997 for Validation Error

Hi All,
I need some clarification on receiving the 997/FA for the Validation error that happens at the remote trading partner.
Will the 997 payload contain the details of the error in it??
How will B2B interpret the FA as positive FA or negative FA?
In my case the payload which I am sending is getting validation error at receiving side, they are sending me the FA. But in my side, both the initial transaction and the ack transaction goes to MSG_Completed state. Is it a normal behavior?
Thanks in advance.
Regards,
Monica

Hi,
1. The 997 has fields which will tell if the EDI transactions has SNIP errors. In your case, the outbound EDI should goto MSG_ERROR.
2. In a 999 transaction, the fields such as AK9, IK4, IK5 will tell the problem in the EDI, I am sure 997 should also have something like that.

ADF validator or JavaScript for client side validation ?

using JDev and ADF 11g
Problem description : To apply validations such as date range check, pattern matching, maxlength etc.. on ADF Faces Components.
Solution 1: Use ADF validator such as Reg Expr validator, Max Length validator
Souliton 2: Write Javascript code for validating the component's value at cleint side.
When using ADF Validator for such type of validation checking, a request is send to the server for processing (additional overhead) . However we can do such validations with javaScript functions without the need to interact with the server. So, what benefit does ADF Validator serves when one needs to implement such validations ?
Please share your views...

H,
afaik, client side validation in ADF Faces suppresses server round trips if a validation error is detected on the client. Only if no problem is found, the server side validation is challenged upon submit (so no extra round trip for validation). Shay is absolutely correct. JavaScript is a convenience but never a solution.
Here's how to create a custom validator with a client and server side implementation : http://download.oracle.com/docs/cd/E15523_01/web.1111/b31973/af_validate.htm#BABEIIDD

How to Disable client side validation for the message text input

Hi,
I have scenario where i need to by pass the client side validation for a message text input
Scenario is
I have a message text input field(say XYZ), i set the max length for the item as 20
Now when im trying to enter the greek characters into it, it is allowing me to enter till 20 characters
But when i try to submit the form ..my client side validation is firing..
The Error says the XYZ is too long
The problem is, in greek each character takes two bytes.(In english it is only 1).While entering the content it allowing 20 characters and when validating it is checking for bytes(if we enter in greek the length will be 40 bytes not 20)
I cannot increase the max length .coz i have restrict the character length to 20 only.(english or Greek).
Please help me in this regard.
Regards
Sandeep.

Thanks for the information.But we dont have any option either declaratively or programatically to disable the client side validation for the message text input..I referred java docs ..i dint find any method which does..
Correct me if im wrong

Client Side Javascript Validation not Working in Struts 1.x version

hi,
I'm following the steps provioded in the below link for Javascript Client side validation but still it is not working.I'm struggling to get this work.
[http://www.visualbuilder.com/jsp/struts/tutorial2/pageorder/9/|http://www.visualbuilder.com/jsp/struts/tutorial2/pageorder/9/]
"The framework automatically generates the browser specific JavaScript and validate the data only at the client side."From the above statement i undertstand that framework itself generates the javascript function for validating the field mentioned in validations.xml file so that we dont have to explicitly write a javascript function for

Do we need to call an explicit function

STRUTS: client-side validation in jsp using DynaValidatorForm

I am supposed to work on struts on as project and it is like learning a crash course and work the next day.
In Struts 1.1 enviroment, I am using DynaValidatorForm to create a bean form and then perform validation.
1. I write a DynaValidatorForm definition in struts-config.xml
2. I write xml for action so that when /getQuotes.do in invoked by a jsp form, the form data is put into the QuoteDetailsBean.
3. add the plugin script for ValidatorPlugIn
xml fragment from struts-config:
//form bean
<form-beans>
<form-bean name="QuoteDetailsBean" type="org.apache.struts.validator.DynaValidatorForm">
    <form-property name="forename" type="java.lang.String"/>
   <form-property name="surname" type="java.lang.String"/>
<form-bean>
</form-beans>
<action
        path="/getQuotes"
        type="com.kainos.quickquotes.struts.QQGetQuotesAction"
        validate="true"
        name="QuoteDetailsBean"
        input="/userform1.do"
        parameter="save"
        scope="session">
        <forward name="success" path="/pages/jsp/result.jsp"/>
        <forward name="back" path="/userform1.do"/>
</action>
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
     <set-property
         property="pathnames"
         value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>Now I write a validation code for getQuotes.do. note that I can write the validation code with
<form name="QuoteDetailsBean"> but this form bean is shared by many jsp, so i am using the name of the action
(getQuotes) as the name of the form in the validation.xml.
So far this looks okay, as I am going by some example.
xml fragment from validation.xml:
<formset>
          <form name="/getQuotes">
             <field property="forename" depends="required,minlength">
                <arg0 key="QuoteDetailsBean.forename" />
                <arg1 name="minlength" key="${var:minlength}" resource="false"/>
                <var>
                   <var-name>minlength</var-name>
                   <var-value>2</var-value>
                </var>
             </field>
             <field property="surname" depends="required,minlength">
            <arg0 key="QuoteDetailsBean.surname" />
            <arg1 name="minlength" key="${var:minlength}" resource="false"/>
            <var>
               <var-name>minlength</var-name>
               <var-value>2</var-value>
            </var>
             </field>
</formset>Now I write the JSP. I use the <html:javascript> tag to allow front-end validation based on the xml in validation.xml.
The jsp code:
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<html:html locale="true">
<head>
<title><bean:message key="welcome.title"/></title>
<html:base/>
<html:javascript formName="/getQuotes"
            method="validateForm"
            dynamicJavascript="true"
            staticJavascript="false"
            cdata="false" />
</head>
<body bgcolor="#FFCC9F">
<html:errors />
<html:form action="getQuotes.do" onsubmit="return validateForm(this);" >
Forename:</td> <td>��<html:text property="forename"/></td></tr>
<tr> <td>Surname:</td> <td>��<html:text property="surname"/></td></tr>
<html:submit value="Quotes" /></td></tr>
</html:form>
</body>
</html:html>Does this looks okay. I wrote so far based on some tutorials n help online.
Now when I open the JSP and then do a submit, there is no validation (I tried by submitting with empty forename and surname. I mean i could invoke the action class and the invoke class
redirects(forwards) to the appropriate path. so the code works fine except validation is not done
Q1. So what should i do more to get client-side validation?
What actually happens in client-side validation? does a pop up alert appears?
nothing happens so far in my case.
Q2. What should I do more for server side validation. Since the form is incomplete, what happens?
I thought the same form returns and the error messages are printed in the jsp page since i have the <html:errors />
tag just below the <body> tag.
The action class is pretty simple so far:
public class QQGetQuotesAction extends Action {
    public QQGetQuotesAction(){
public ActionForward execute(ActionMapping mapping,
             ActionForm form,
             HttpServletRequest request,
             HttpServletResponse response)
    throws Exception {
        DynaValidatorForm dynaform = (DynaValidatorForm)form;
        System.out.println("forename:"+dynaform.get("forename");
        System.out.println("surname:"+dynaform.get("surname");
        return forward=mapping.findForward("back");
}Please help me out. I think I am missing something which i need to do
thanks

I think the validations are to be declared on the form
name and not the action path.
Your formName is QuoteDetailsBean but your are using
the action path(/getQuotes) both in the validation
rules and the jsp tags. Use the formName on both the
places.
Also your html:javascript tag will not generate the
static javascript to validate the fields. For this you
will have to add code like below.
<html:javascript dynamicJavascript="false"
staticJavascript="true"/>
Other options is to set the attribute
staticJavascript="true" in your html:javascript tag.
Hope it helps.hi
staticJavascript="true" did the trick. :)
I think the validations are to be declared on the form name and not the action path.It is not necessary. You can declare the validation on the action class. This is essential if a form bean is shared by several JSPs having its own action class. This is as per as I read in a tutorial and it works.

Client side validation in struts using validation framework

Hi ,
am new to struts.....
I want to validate a simple login page using struts validation framework...
For that i created,
login.jsp ( contains html:errors and html:javascript and onsubmit)
LoginForm extends ValidatorForm
LoginAction
resource bundles
validation.xml ( required, minlength and maxlength rules for both fields)
struts-config.xml ( configured action mapping and form beans)
whats my problem is....
i will get error messages through server side validation...
i cant able to get the error messages using javascript i.e alert messages.
i seen the page resource in that all javascript functins are inserted.
on seeing the javascript error console... it shows
formName has no properties...............
exactly at this line
oRequired = eval('new ' + formName.value + '_required()'); //function validateRequired(form)

Thanks for your valuable reply.....
Ya of course what you said was correct....
I got error messages while submitting the form without any value....
error messages are displayed using the <html:errors/> tag (server side validation ).
But it fails to show the alert messages for those errors ( client side validation).
i inserted the <html:javascript formName="form bean name" /> tag in the bottom of my login jsp.....
on seeing the error console, it shows formName has no properties.
Could anybody help me to sort out this problem........
