This web service developed to give multiple services 
with a single published web service. Many services with one 
web service concept is achieved by service routines which 
are loaded dynamically.


This is developed with java and is a RPC based web service. 
This web service has two input String (xml string) parameters 
and a String (xml string) output parameter. The first parameter 
gives the user credentials, i.e. user id, password, and a function 
code. Other parameter gives the data required for the service routine 
to carry out its processing. 

The function code passes to the 
Web service determines which service routine is to be called. 
The web service validates and authenticate the user id, password and 
the function code. If validations are ok the service routine 
corresponding to service is dynamically loaded and gives control
to it. This is handled by in built login module 
which is also dynamically loaded and can also be replaced. 

The user ids, passwords, function codes, service routines, etc.
are defined in xml files. The service routines which are java classes 
and exist in specified folders or exist inside specified jar 
or zip files. 

To give a new service one has simply need to write 
a service routine and put it to a specified folder or specified jar 
or zip file. No web service is required to be developed  
nor server nor application is needed to be restarted to give new 
service.

First parameter : xml string 

       <msg>
          <userid>ajkd</userid>
          <password>abcd1234</abcd>
          <funcid><ACDETAIL</funcid>
       </msg>

Second parameter : String. which will be used by the service routine 
                   corresponding to funcid.
                   could be somthing like
                       <account>
                          <no>124789</ac>
                       </account>
                   or could be simple string such as "124789"
                   and depend on how service routine built to accept it

Output parameter : xml string.
            <rmsg><rcode>0</rcode><msg>output from client</msg></rmsg>
                 rcode "0" means everything is ok 
                          <msg> has the output from service routine. 
                 if rcode is not "0" means error and 
                          <msg> will give the reason.                  



Inbuilt login module use two xml files

  User credential xml file 

          uprof.xml

               <uprof>
                  <user>
                     <id>ajkd</id>
                     <password>abcd1234>
                     <status>A</status>    ---- profile is in active state
                     <funcid>BALINQ+ACDETAIL+TRANLIST</funcid>                                   
                  </user>
               </uprof>

              User “ajkd” given permission to functions BALINQ, ACDETAIL and           
                   TRANLIST

  Functions definition xml file 

           ufunc.xml

               <ufunc>
                 <func>
                   <id>BALINQ</id>
                   <uer>devuws.balinq+process</uer>                     
                   <status>A</status>
                 </func>
                 <func>
                   <id>ACDETAIL</id>
                   <uer>devuws.acdetail+getdetail</uer>
                   <status>A</status>                 
                 </func>
                 <func>
                   <id>TRANLIST</id>
                   <uer>devuws.actran+getlist</uer>
                   <status>A</status>                 
                 </func>
               </ufunc> 


               “devuws.balinq” is the service routine class BALINQ function
               method that will be called is “process”


All these tables are defined in a property file 

               devuws.propeties. 

LIBDEF     file:c:\\ajkd\\devuws\\build\\,file:c:\\ajkd\devuws\\uer.jar     
uprof      c:\\ajkd\\devuws\\uprof.xml
ufunc      c:\\ajkd\\devuws\\ufunc.xml
LOGINUER   devuws.login+doLogin

LIBDEF   - defines the service routines existing folders, jar and zip files.
           for linux environment LIBDEF would
           be something like /ajkd/devuws/build,/ajkd/devuws/uer.jar 

uprof    - location of the user profile definition xml file

ufunc    - locaion of the function definition xml file

LOGINUER - defines the login handling routine. “devuws.login” is the in built    
           Routine and “doLogin” is the the method to call by the main
           application.
