Active Directory and Weblogic Application Data Source

DLopezFeb 18 2016 — edited Feb 23 2016

Hi,

I've been asked to find a way to save Users information created through Active Directory in my application datasource so my application can check if the user as authorization.

My application, services to fetch the data and datasource will be in the weblogic.

What I found so far was that there as to be a Active Directory Provider in the weblogic to do the authentication, and it will work similar to SQL Provider, puting all users and groups in the weblogic.

Basically what I think I have to do is create something ( service or DB package function maybe ) that will somehow establish the synchronization between both AD and my database.

How can I do it, or there is an easier way to do it?

Thanks

If you have multiple item tags:

SQL> with t as (
  2  select xmltype('<?xml version="1.0"?>
  3  <purchase_order>
  4  <po_items>
  5  <item>
  6  <name>#Name#</name>
  7  <quantity>#number#</quantity>
  8  </item>
  9  <item>
 10  <name>#Name2#</name>
 11  <quantity>#number2#</quantity>
 12  </item>
 13  <item>
 14  <name>#Name3#</name>
 15  <quantity>#number3#</quantity>
 16  </item>
 17  </po_items>
 18  </purchase_order>') xml from dual)
 19  select x.*
 20  from t, xmltable('/purchase_order/po_items/item' PASSING t.xml COLUMNS

I'm not think this to get in result:

NAME                 QTY
----------------    -----------------
#Name#             #number#

in my result needs

VALUE                PATH
--------------      ------------------------------
#Name#            /purchase_order/po_items/item/name
#number#        /purchase_order/po_items/item/quantity

Massimo Ruocchio do you have some ideas??

In Oracle 10g:

SQL> with t as (
  2  select xmltype('<?xml version="1.0"?>
  3  <purchase_order>
  4  <po_items>
  5  <item>
  6  <name>#Name#</name>
  7  <quantity>#number#</quantity>
  8  </item>
  9  </po_items>
 10  </purchase_order>') xml from dual)
 11  select x.val, 
 12         '/purchase_order/po_items/item/'||xmlquery('for $i in /* return name($i)' 
 13                                                    PASSING x.col RETURNING CONTENT) path
 14  from t, xmltable('/purchase_order/po_items/item/*' PASSING t.xml COLUMNS
 15                   val varchar2(20) PATH '.',
 16                   col xmltype PATH '.') x;

VAL                  PATH
-------------------- --------------------------------------------------
#Name#               /purchase_order/po_items/item/name
#number#             /purchase_order/po_items/item/quantity

In Oracle11g the following should work:

with t as (
select xmltype('<?xml version="1.0"?>
<purchase_order>
<po_items>
<item>
<name>#Name#</name>
<quantity>#number#</quantity>
</item>
</po_items>
</purchase_order>') xml from dual)
select x.val, 
       '/purchase_order/po_items/item/'||x.col path
from t, xmltable('/purchase_order/po_items/item/*' PASSING t.xml COLUMNS
                 val varchar2(20) PATH '.',
                 col varchar2(20) PATH 'name(.)') x;

Pitty you did not mention your db version.

putting together some functions from FunctX one can write

<quantity>#number#</quantity>

But there you give a static value #number# and #Name#, but in my case. I need select all names what is in xml and get path of them!

Thanks anyway...it's helpful anyway :)

there you give a static value #number# and #Name#

can be avoided of course:

SQL> with t as (

Thanks a lot. Now I try to get understand the code I use it. I hope it's works fine.

This will works fine:

</frame>
#DOME#

it's will select the dome and path of it??

Works like I need, but with one difference. There select all xml elements where is text.

But I need to select path and #variables# only!

for example:

with your code I get in result:

office.text/text:p	L?muma Nr.#numurs#

but I need:

office.text/text:p	 #numurs#

and places where not this #varaible_name# don't select into table!

Thanks for help! :)

if i understand you properly...you have a xml..and inside it you want to get a all node paths for a particular text.

there is xml where nodes text ar:

purchase_order/po_items/item/quantity              #number#

just use a simple regular expression after getting data like above.

regexp_substr(nodevalue,'#.*#')

Scrapping the data is difficult after that we can use our normal oracle functions to modify the data in the manner you want. ;-)

Please can you help me little bit more :) how can I put these values into table of record? :)
Theres code:

this is code in package:
TYPE Var_Names IS RECORD
 (
   v_name     VARCHAR2(100),
   XPath      VARCHAR2(500)
 );
 TYPE Var_Name_List IS TABLE OF Var_Names;

 Variables Var_Name_List;

this is code in body package:
  FUNCTION selectVariablesInList(tempXML XMLType) RETURN Var_Name_List
    IS
    BEGIN
      WITH tab AS
      (SELECT tempXML col
        FROM dual
     )
     SELECT nodepath, regexp_substr(nodevalue,'#.*#') nodevalue INTO Variables

      FROM tab t,
     xmltable('
       for $i in $tmp/descendant::*
         where $i/text() != ""
        return <R><P>{string-join($i/ancestor-or-self::*/name(), "/")}</P><V>{$i/text()}</V></R>' 
        passing t.col AS "tmp" columns
      nodepath varchar2(50) path '//P',
      nodevalue varchar2(50) path '//V'); 
    
     RETURN Variables;   
    END;

you need to use sql types not pl/sql records for using inside sql queries within functions...check this it will be useful....replace the code as required for you...

can't save the values into record based table???

754085

If I make object, then it's not saves into package but into type folder. I want all in one place!

ravikumar.sv

you can do it...but it's a bit tedious to execute....
and the worst thing is you cannot call a function inside a query(as I shown in the last statement of above post) to obtain data, if you define return types to be pl/sql record types,so better they be sql types.

and also this will be easy method to access data for an input xml...
just a simple query needs to be run ...
instead of running a pl/sql block, retrieving the data,copying into local variables and looping on that data.

But I Don't need from sql get these values in the end. I need this list to replace values from databases and do some work with xml , update it and then return xmltype like blob into database.

MichaelS

this is simpler...

Right. Should simply have searched a bit more intensively to find path-to-node ;)
