Hi guys in this post we are going to create a Simple Pass through Proxy in Oracle Service Bus. I hope you have successfully setup your OSB configuration project, if not please follow my previous post here. Now moving on to Develop your first OSB project.
Step 1--> Right click on your OSB configuration project and select Oracle Service Bust project

Step 2--> Give it a name. I have given Calculator since i am going to connect OSB to an external web service(calculator). U can give any name.

Step 3--> Now right click on ur Project and create four folders i.e, WSDL, Proxy, Business Service and XSD. Its always a good practice to keep all your files in respective folders.

Step 4--> Now copy XSD and WSDL files of your existing service in respective folders.[Note: You need working WSDL and corresponding Schema files of an existing service. i.e you need a running web service which you want to call from your OSB. You can get free web service WSDLs from here ]

Step 5--> Now right click on Business Service folder and new Business Service give it a name. I have given CalculatorBusinessService.

Step 6--> Now Select WSDLweb service--> browse--> provide wsdl file location-->Select port of your WSDL. Finish and override previous transport configuration.

Step 7--> Now right click on Proxy folder and create new Proxy service. Give it a name. I have given

Step 8--> Now you need to configure the proxy with the same WSDL file. Select WSDL web service and provide the wsdl file location and select port--> Finish and override the previous Transport configuration.

Step 9--> Now click on Message Flow tab in CalculatorProxyService.

Step 10--> Drag a route node from Oracle Service Bus Message Flow(Right Hand side)

Step 10-->Drag a routing node from Route Actions

Step11--> In Routing Service* provide a link to your Business Service. So that your Proxy directly routes to the Business Service.

Click on ok .

Now You are ready to deploy your OSB project. To deploy right click on configuration project and run as server.

Work Flow:
Client--> Proxy Service-->Business Service--> External Service
1) Business Service: Wraps the external Web Service and provides an extra layer of abstraction .
2) Proxy Service: Routes requests coming from Client to that Business Service. And provide response back to client

First Step to Oracle Service Bus (Creating Oracle Service Bus Configuration Project)

noreply@blogger.com (GadgetsByBG) — Tue, 22 Dec 2015 16:30:00 +0000

Hi guys, today i am going to show you how to create an Oracle Service Bus Configuration Project. Remember that all of your OSB projects will be running under the configuration project

Step 1: Open Eclipse-> go to file --> new--> select other-->select oracle service bus

-> Select Oracle Service Bus Configuration project. Click next--> Give a name to the configuration project--> Finish
Step 2: The configuration project is not associate with any server yet. So next step is to connect a server with the OSB configuration project. Click on server tab--> Right click on blank space and select new server.

Select the server that is installed in your system. In my case itsOracle Weblogic Server

--> Give the Weblogic Server installation directory(Weblogic Home) and java home will be automatically selected.--> Click next--> Now you have to choose your Weblogic Server Domain from the browse option. (The domain should support OSB develpoment). If you have not created a OSB domain then please click on create domain.

--> Give it a name and location where it will be created--> select Oracle service bus for developers check box(Mandatory). Click on finish.

--> Yeeee !!! You are ready to start with OSB.. but remember to start the Weblogic server before creating your first OSB project.For this go to the Weblogic Domain which you have just created and click on startWebLogic.

In our next post we will be creating a basic OSB project including one Proxy service and business service and deploy it.

LATEX Tutorials

noreply@blogger.com (GadgetsByBG) — Wed, 02 Apr 2014 13:25:00 +0000

Hey guyzz. having problems with LATEX??

Use following Steps to ease your problems:

[FOR WINDOWS ONLY]

A. Installations Guides

STEP 1.
Use text editor like TEXMAKER. Downlaod here
install it with default settings.

STEP 2.
Download Latex ( For windows it is called MIKTEX) Download from here and install it with default settings i.e. full installation.

B. Basic Documentation using Miktex

First open texmaker and follow the video below to get started

Now write your document as per your requirements. We have provided some basic codes(in red) below

i) To add new line use \\

ii) To add chapter use \chapter{chapter name}

iii)To use section write \section before your text.

iv) use \par before any text to create a paragraph.

v) To insert figure or graphics use following codes
\begin{figure}[!h]
\begin{center} ( If you want your figure to be centered)
\includegraphics[scale=1]{folder name/image file name}
\caption{ name of the figure you want to be displayed \label{any name which will be used to refer the figure}. }
\end{center}
\end{figure}
1. ( NOTE:: KEEP ALL FIGURES IN THE SAME DIRECTORY AS THE LATEX DOCUMENT IS SAVED)
2. (NOTE: \label is used if you want to refer your figure anywhere in the text.. USE \ref{label name } to refer that figure)
3. (NOTE: For example \includegraphics[scale=1]{images\mypic.jpg} [ Here images is folder name and mypic.jpg is the file name]
4. ( NOTE: \usepackage{graphicx} use this at the beginning of the document to use command like \includegraphics )

vi) To insert bullets use or numbering
\begin{itemize}
\item[1.] item name
\item[2.] item name.
.....
...

\end{itemize}

vii) To cite any text use ~\cite{any name}

(NOTE: In the bibliography file just use that name and fill up details)
A sample bibliography file is shown below
For example if you have cited a text as ~\cite{p2} and it is a book then use following
@book {p2,

AUTHOR="author name",

TITLE="book title ",

VOLUME=,

PUBLISHER={publisher},

YEAR= year of publication

}

if its in a proceedings then ...

@INPROCEEDINGS {p10,

AUTHOR="Author name ",

TITLE="Title of paper ",

BOOKTITLE="Publication or presentation venue",

YEAR=Year of publication,

}

viii) To insert a table use

\begin{longtable}{|p{2cm}| p{2cm}|p{3cm}| }
\caption{name of table}\\
\hline
enter column elements as :
COLUMN1 & COLUMN2 & COLUMN 3
\hline
(NOTE:Here {| | | | } means three columns are used and their size will be 2 cm 2cm and 3cm respectively.
\hline indicates a HORIZONTAL LINE
\\ indicates a new line )

vii) Latex doesn't support direct insertion of some special characters and mathematical formulas. If you are having problem inserting them check the following figures.

(NOTE: if you want to use any mathematical formula use \( your formula \).. Now if your formula consists of above characters then use those commands accordingly.)
Example: \( x+y \)= x+y
\( \log m + \log n \)= log m +log n
REMEMBER: Don't use any space between \ and brackets.
