Pattern for email attribute validation.

I generated an schema for a web service which includes an email attribute, for which I developed a pattern to filter invalid emails but I'm getting facet errors during the schema object creation. My schema works perfectly well in XMLSpy but Oracle's XML parser/schema object fails.
the pattern I am using is:
"([a-zA-Z0-9_\\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)"
which includes some OR logic and nested patterns to validate the email.
I was able to track that using something like (([a-zA-Z0-9\-]+\.)+)) would not be correctly validated in Oracle's XML parser and that \. will cause the schema object creation to fail with facet errors.
I do not know if this is related to the current implementation of the validating parser or something else but I cannot find information on the current implementation that oracle supports (besides a version number). Where can I find information on this... does anyone happen to have a pattern which will validate email addresses and work under oracle parser?
Thanks,
Fedro

Yes, this may related to our implementation for the regular expressions.
Would you send me a simple test case at [email protected] If this is bug, we will fix it.
Thanks.

Email id validation regexp

Hello all,
Can any body please help me in writing a reg exp for email id validation that would cover all possibilities of validating a email id?
I had tried searching few on net but some test cases for the same faild.
thanks in advance

Do you have actual requirements for this?
Why does that matter - well look at the links posted and read them for the complexity of validating that an email address is valid in terms of the RFE that defines it.
However, note that despite that such an address might not work at all. Even though it is perfectly valid.
So if your requirements are to only accept email addresses that work then you need something quite a bite more complicated that simply validating that it meets the RFE. And if you don't need an address that actually works then does it matter if it is valid or not?

Email address validation, is there a way to use Regex or other fuzzy searching?

I would like to use PL/SQL for Email address validation, is there a way to use Regex (regular expressions) or some other fuzzy searching for that? Using % and _ wildcards only take you so far...
I need something that will verify alphanumeric charectors (no ",'.:#@&*^ etc.) any ideas?
Current code:
if email not like '_%@_%.__%' or email like '%@%@%' or email like '% %' or email like '%"%' or email like '%''%' or email like '%
%' then
The last line is to make sure there are no linebreaks in the middle of the email address, is there a better way to signify a line break, like \n or an ascii equivilent?

Michael:
The as noted in the previous post, DBI is a Perl package that allows Perl to talk to various databases, including Oracle. We use DBI on several UNIX servers, and it does not require ODBC, and I have always found it to be extremely quick. Things may be different in the Windows world.
If you are spooling files out to run through Perl anyway, you may want to take a look at DBI. You could probably modify your existing scripts to use DBI fairly easily. The basic structure using DBI is like:
use DBI;
my dbh;       # A database handle
my sth;       # A statment handle
my sqlstr;    # SQL statement
my db_vars;   # Variables for your db columns
# Connect to the database
$dbh = DBI->connect( "dbi:Oracle:service_name","user/password");
$sqlstr = 'SELECT * FROM emp WHERE id = ?' # even takes bind variables
#Prepare statement
$sth = $dbh->prepare($sqlstr);
$sth->execute(12345); # Execute with values for bind if desired
# Walk the "cursor"
while (($db_vars) = $sth->fetchrow_array()) {

The last two are the only valid edit patterns. All of the others are invalid. Here are the reasons:
- You have to specify the minutes
- If not using military hours (H, HH) you have to specify AM or PM
The only way to support the other patterns you are trying to use is to make it a text field and put
custom javascript validation on it.

Email address validation pattern

First off, I'm using JDK 1.4.2_07. What I'm trying to do is validate email addresses with the String.matches(String pattern) function. What I'm having a problem with is coming up with the regex pattern that represents any syntactically valid email address. If someone has a regex pattern that does represent any syntactically valid email address, I would appreciate it if you posted it in a reply to this message. Thanks!

Validation error message is not displayed for an attribute as an Input List Of Value

Hi everyone,
I use jdev 11.1.1.7.0
In my application I've created an Entity Obj and a View Obj base Employees table.
for the JobId attribute I've taken actions as listed below:
1. in Employees EO I've created a validation for this attribute and in some cases an error message returns (the error message is "the salary is not high"):
 * Validation method for JobId.
 public boolean validateJobId(String jobid) {
 if (...) {
 return false;
 if (...) {
 return false;
 if (...) {
 return false;
 return true;
2. in Employees VO I've created a LOV for this attribute (the view accessor is JobsViewObj ) and I display the attribute as an Input Text with List Of Values.
in jspx page I drag& drop this attribute as below:
 <af:inputListOfValues id="jobIdId"
 popupTitle="Search and Select: #{bindings.JobId.hints.label}"
 value="#{bindings.JobId.inputValue}"
 label="#{bindings.JobId.hints.label}"
 model="#{bindings.JobId.listOfValuesModel}"
 required="#{bindings.JobId.hints.mandatory}"
 columns="#{bindings.JobId.hints.displayWidth}"
 shortDesc="#{bindings.JobId.hints.tooltip}"
 autoSubmit="true">
 <f:validator binding="#{bindings.JobId.validator}"/>
 </af:inputListOfValues>
I open the Popup and I select a row from the Popup list and then I click Ok. After that if the validation method(validateJobId) returns false, the error message("the salary is not high") must be show to the user. but the error message doesn't display. I don't understand why this happens.
Can anybody guide me about this problem?
Regards
Habib

yes, you're right, I've tested it in 12.1.3 and error message was displayed.
it seems it's a bug(bad bug ) in both 11.1.1.7 and 12.1.2. and now what can I do? is there any way to display the the error message?

Habib

How to set which User Profile attribute is used for email messages?

I am having a problem setting up User Profiles in SharePoint 2013. I have users that are both (1) Active Directory users authenticated using Windows Authentication, and (2) Active Directory users, existing in another distinct OU, authenticated via ADFS (active
directory federation services).
My problem is with the ADFS users. I want to have the users unique id be their logon email account ([email protected]), but want to populate their work email attribute with their "actual" or real email account.
If I have an OU (External Users) and within that OU (XYZ Company Users), AND my domain is contoso.com, then I want to add a user such that they have a unique id in active directory ([email protected], but want their email address to be whatever
it is (I.e. [email protected]).
MY PROBLEM: I can setup the User Profile Synchronization service to map the properties perfectly, but when I I try to add/share a user in a SharePoint site, the user's account email ([email protected] is sent the message, not their "Work Email"
([email protected]).
QUESTION: How do I get SharePoint to use the "Work Email" attribute (NOT the account email) of a User Profile when sending email messages?

Okay, within Active Directory, the user's email IS set to
[email protected] The "unique value" (Using the account logon name) works just fine. The problem is SharePoint. When I logon with another account and choose to share a site with this particular test user, the Email for sharing the site is sent to
[email protected] (the account logon name), not
[email protected] (the user's email address)
How do I get SharePoint to actually use the email address of an AD user, and not use the account logon name when sending notifications?

Validation for 2 attributes in a single expression

Hi All,
I have a scenario such that I need to make 2 attributes as mandatory when I chose a particular
Category node.
Now I am able to write, execute validation for one attribute but when I write for 2 attributes, only the first
attribute is being considered. Even if the second attribtue is not present, it says there are no errors.
Regards,
Pramod

Hi Pramod,
I have tried this thing at my side and its working fine.
Please check the steps below:
1. Create new validation and dont write any thing in the expression.
2. Add a branch to this validation and select the node which you want to validate.
3. Inside the branch expression just write IS_NOT_NULL(Attribute1) AND IS_NOT_NULL(Attribute2)
select Attribute1 and Attribute2 from the Attributes list.
4. Run the Validation.

Patterns for attribute in a schema?

How do you set the patterns value for an attribute in a schema file?

The XML representation for a pattern schema component is a pattern element information item. The correspondences between the properties of the information item and properties of the component are as follows:
XML Representation Summary: pattern Element Information Item
<pattern
id = ID
value = string
fixed = boolean : false
{any attributes with non-schema namespace. . .}>
Content: (annotation?)
</pattern>

Attribute validation error for tag CFQUERY

I have a CF application that's running fine on a shared host. I now have a VPS running version of CF 9. When I try to use this on the VPS, I get the following error:
Attribute validation error for tag CFQUERY.
The value of the attribute datasource, which is currently '', is invalid.
The datasource is being set in application.cfc, and again works just fine in the shared environment.
The only differences is the shared is running on Windows, and the VPS is Linux. Also, the Windows is running version 9,0,1,274733 and the Linux is 9,0,0,251028
Any help would be greatly appreciated.

The cause of the error is obvious. Somewhere in your application, the cfquery tag is used as follows, with an empty string as datasource:
<cfquery datasource="">
</cfquery>
That is a mistake. The error message should tell you where that occurs.

How can I use database constraints in entity attribute validation rules

I am interested in using database constraints to validate attributes in entity objects.
I would like to implement a JboValidatorInterface in a way that I can use an operator like "GreaterOrEqualTo" to compare with values retrieved from the database for a column associated with an entity object attribute.
I have used this pattern with success in other environments, where the user community decides the minimum value for a thing should change from x to y, and simply changing a database object also changes the validation methods of all applications which access it.
I am not certain that column constraints are the appropriate vehicle, but so far that seems to be the case.
I see that you can create a validation rule which makes comparisons against a view object attribute. I am wondering if there is a generic way to use standardized names for column constraints along with ADF hooks into properties of database columns, to avoid writing individual queries for each attribute.
Thanks in advance!!!

Jeffrey,
If you already have constraints on the underlying tables, why do you need to validate them in ADF BC? You can certainly use some framework extension classes to give the user nicely formatted error messages - see ER: ADF BC - allow custom error msgs for common exceptions (e.g. DML) for more details.
I am using this method so that anything that is enforced in the database (check constraints, foreign keys, unique constraints, etc) are not enforced in the ADF BC layer as well - after all, there's more than one way to get data into a table, and DB constraints ensure that even if data gets in through another mechanism (apart from the ADF application), it is valid. My 2 cents, of course.
Hope this helps,
John

TREX python extension for HTML attribute extraction

How is the TREX python extension for HTML attribute extraction supposed to work?
I activated this extension and indexed an HTML document containing:
<HTML>
<HEAD>
<META content="debian, GNU, linux, unix" name=Keywords>
<HEAD>
<HTML>
Why when submitting the query "unix" this document is not found by the system?
(TREX version 6.1.11.02)
Davide

The trick doesn't work on my system (TREX v. 6.1.11.02).
1) This is the edited line in getDCAttributes.py:
knownAttributes = ['description','Keywords']
2) Only the HTML Attribute Extractor extension is activated in extensions.py. In particular, the Dublin Core extension is deactivated.
3) This is the pythonextension section of TREXPreprocessor.ini:
extensiontype= beforeHTTP
4) This is the parametrization of the newly created property in CM:
Unique ID: html_keywords
Description: not set
Property ID: Keywords
Namespace Alias: trilog
Type: String
Group: html
Mandatory: not checked
Multi-Valued: not checked
Read Only: not checked
Maintainable: not checked
Indexable: checked
Default Value: not set
Allowed Values: not set
Key for Label: not set
Meta Data Extension: not set
Folder Validity Patterns: /
Document Validity Patterns: /
Resource Types: not set

Default Sorting Ascending: not set
Label Icon: not set
Hidden: not checked
Dependencies: not checked
Additional Metadata: not set
Property Renderer: not set
Virtual: not checked
Composed of: not set
Comparator Class: not set
5) I've added this property in the parameters Allowed Predefined Properties and Predefined Properties under Content Management -> User Interface -> Search
6) Now it's possible to filter by the Keywords predefined property in the Search UI, but no matches are ever found.
7) No significant message is found in PythonExtension.log:
# running global extensions.py at Tue Jul 12 11:13:03 2005
### import getHtmlAttributes
# running global extensions.py at Tue Jul 12 11:13:04 2005
### import getHtmlAttributes
8) I've run another test activating the Dublin Core extension in extensions.py as well, and setting extensiontype to beforeLEXICON in TREXPreprocessor.ini. Nevertheless it didn't work.
9) Here's some DC extension's output:
### Parse document with key: '/davide_test/attributi/GNU_Emacs.htm'
### extracted attributes: []
This is the GNU_Emacs.htm's <head>:

CVP Opsconsole: Patterns for RNA timeout on outbound SIP calls - Dialed Number (DN) text box does not take any input

Hi there,
I'm having problems modifying the 'Dialed Number (DN)' text box under 'Advanced Configuration->Patterns for RNA timeout on outbound SIP calls' of the SIP tab in the Cisco Unified Customer Voice Portal 8.5(1) opsconsole. In a nut shell, I need to change the RNA timeout but some reason when typing into the Dialed Number text box, the input is not taken. The reason I want to change this settings is because my ICM Rona is not working with CVP:
https://supportforums.cisco.com/thread/2031366
Thanks in advance for any help.

Hello Dale,
CVP doesn't allow you to exceed the RNA more than 60 Seconds. If you want to configure the timer for DN Patterns you should do it via OPS console, It would update the sip.properties files in correct way, the above way is incorrect.

Are these errors or warnings? If warnings, you should be able to just ignore them.
