7/25/2019 2.Develop a Synchronous Service for Division of Two Numbers (1)

1/26

The Start up scripts for starting admin server and soa server will be available in

Middleware home\ user_projects\domains\murali_domain\bin

In my case : C:\racle\Middleware\user_projects\domains\murali_domain\bin

!evelop a synchronous application which will accepts two numbers as input"

performs division of two numbers and returns the output#

$# Start the weblogic server%&dmin server'

If you want to start the weblogic server later run the command from the command prompt:

[email protected]


2/26

on successsful start of the admin server the following message will be displayed at the comand prompt:


3/26

&ow open the browser and give the following url:

http:44localhost:50014console

user name: weblogic

password: welcome12

now under muralidomain4environment4servers

we can see the admin server up and running:

[email protected]
http://localhost:7001/consolehttp://localhost:7001/console

2. Starting Soa server

7or this go to :89racle#oaMiddleware8userproects8domains8muralidomain8bin

And run startManagedWebLogic.bat soa_server1 http://murali:71 or

And run startManagedWebLogic.bat soa_server1

9n successful start the follwing message will be displayed:

&ote : soa server will ta;e + mins

[email protected]
http://murali:7001/http://murali:7001/


5/26

&ow if we refresh in the admin console the status of the soaserver will be changed to running as shown below:

3 . Now open the Jdeveloper

The Jdeveoper view will be as shown:

Create a new project under the same application where you have created

Clic( on )e*t+

)ow here we need to select the type of composite we want to develop,e are going to develop composite which will have one bpel process# So select

composite with BPE process and clic( on -nish#

7/26

nce you clic( on -nish our application and project will be created and prompted

for creation of our bpel component as shown below:

.or the /pel process provide the details re0uired:)ame: give some meaningful name say for e*#" Synch!iv1rocessor)amespace: either you can leave the default value provided for this or change

what ever you want:http:22*mlns#friend3corps#com2Morning/atch1racticse_jws2Synch!iv2Synch!iv1roce

ssor4nder template drop down select !"nchronous bpel process#now clic( on o(#

This has completed creating our basic components.or any bple project there will be one default *sd will be created and will be

available under #sdfolder name# in our case the -le name is

!"nch$ivProcessor.#sd. !ouble clic( on this -le and modify the *sd to hold two

simple elements for input and one simple element for output as shown

)ow double clic( on Synch!ivprocessor#bpel -le# It5s contents will be displayed

under editing area#

The bpel will be used for implementing business functionality# 6ere the

functionality is nothing but get the re0uest%consisting of two numbers'" perform

the addition of those two numbers and return the result#)ow we have to build an arithmetic e*pression %div_result 7 number$ div

number8'#.or this drag and drop the assign activit"from component palette as shown

below:

10/26

)ow double clic( on the assign activity# )ow the assign activity will be opened#9o to general tab and give proper name for activity say

&ssign_divisionresultTdiv_resultSelect copy operation available under cop" operationtab#

)ow the create copy operation window will be displayed as shown below:

11/26

The left hand side variables are the ones based on which we want to build our

e*pression%number% divnumber&'ight hand side variable are the ones to whom we want to assign the result# In our

case we have to assign to div_result available under out put variable :

)ow we have to buld the e*pression number% divnumber&..or this purpose select e*pression under type in from

)ow clic( on the e*pression bulder as shown below:

13/26

)ow the e*pression builder will opened as shown below:

14/26

)ow e*pand input variable till number$ and number 8 as shown below:

15/26

)ow select number $ and clic( on insert in to e#pression. this will inser the

number$ in to the e*pression area as shown below

[email protected]


16/26

)ow we have to place the divoperator# .or this go to mathematical functions as

shown below

17/26

)ow clic( on o()ow you can see e*pression in from area as shown below:

18/26

)ow the e*pression will loo(s li(e below:

19/26

)ow insert the number8 as you did for number$ and clic( on (#)ow the result has to be assigned to div_result available under output variable#

.or this e*pand the output variable till div'result and select thediv'result.

)ow compile" !eploy and test the application as you did for synch&dd#

Scenarios: number$7; and number8 7< then div_result78 number$7= and number8 7 < then div_result7= number$7> and number8 7 = then div'result()n*nit".

So we should not do division when the number8 7=#So we should chec( the value of number8 if it is e0ual to =%3ero' then we shouldn5t

do div# show some error message saying ?number8 value can not be 3ero@.+ther wise do the div and show the div'result to end user.!o to per,orm this checking we have activit" called switchactivit".)ow drag a switch activity before the assign activity as shown below:

Switch activity will be having two branches$# Case branch A which we can use to test some condition# If the condition is true

then case branch will be e*ecuted# Case branch is mandatory and we can have

any number of case branches#8# ther wise A this branch will be e*ecuted when the condition speci-ed in case

branch is false#This is optional and we can have at ma* one otherwise bloc(#

22/26

)ow clic( on the condition and provide the following values:Babel: number8 e0uals to 3ero!escription: if number8 e0uals to 3ero then we should not perform division

operation#

)ow we have to build the e*pression %if number87='# So for this clic( on the

launch e*pression builder as shown below:

23/26

)ow build the e*pression on number 8 element as shown below

25/26

)ow we are done with if number is not e0uals to 3ero#)ow we have to ta(e assign activity in to case branch and assign the te*t
