Domain Value Map(DVM) in BPEL, Use in SOA BPEL Transformation file

Domain value mapping(DVM) is very useful feature of BPEL that you can use to transform one vocabulary to another. You can change one value to another. Recently i had a requirement to convert Arabic values to their corresponding English values. So i used DVM in my Transformation fileto perform this.
 Following are some steps to to use DVM in your BPEL and Transformation file to map one value to other.
1) Right click on Project and search type dom you will find Domain Value Map, select it and click ok.

2)  Give name and then in first domain name give some name like Arabic value in my case and give its value i.e in Arabic. Now give the name to second Domain Value like English Value in my case and give Value in English like i did. i.e first Domain value has value in Arabic and second domain value has value in English, click OK

3) Now .dvm file opens and here you can add as may values as you want like i have shown below snap.

4) Now to add this DVM to your Transformation file, go to transformation file and then choose advance functions from Drop down and then select DVM functions and then drag and drop lookupValue1M to your xsl file as shown below.

5) Double click and open newly dragged function and give the following detail to your dvm function. Click on Search icon to find DVM file in dvmLocation field, then also select your source and target column name i.e i am converting from Arabic to English so Arabic is my source value and English is my target value. Now you need to select source value i.e which value you want to change, in my case I am converting Arabic UOM to English and that Arabic value in Coming in UOM field so i will select that, you need to hit Ctrl+Space and here you can see you variables .

I hope this would help.

I was doing following guide to develop a service using Oracle Application Adapter Using Business Events

http://docs.oracle.com/cd/E12839_01/integration.1111/e10537/T430238T430579.htm

but no instance was getting created in Enterprise manager console. then i checked my Apps Adapter in Weblogic console and that was not in OK state. I had configured cluster environment and there were two SOA servers. I had to remove the target from 'cluster' and target it only to WLS_SOA1 server and then i updated and saved it and it started working fine without giving the above error.

Then again i created an Invoice (I was calling invoice Event) and instance created successfully in Enterprise manager console.

Bridged Adapter problem, Host-only adapter problem Linux solved

From couple of weeks i was facing problem while setting my network setting in Virtual box. I explored lot of resources but unable to solve that problem. At last i figure out the issue and solve this problem and now i am sharing here and it could saves much time of others whom are facing the same issue.

 When i tried to choose bridge adapter or host-only adapter then i was facing the "no bridge adapter is selected"  or "no host-only adapter is selected" respectively. here are the snapshot to clear the problem.

I was using window 7 as a host and Virtual box which have Linux based environment for guest system. I wanted to communicate both of these machines but could not. Now what was the issue that i was facing :) little strange.

Open your network and sharing center in host machine i.e Window 7 in my case you will see disabled your network for virtual box. Please see the following snapshot for more clear idea.

oh the host-only network was disabled here and similarly others except my host machine network. Just right click on it and enable it. Now go to your virtual box and got to settings again and choose network setting and this time when you will choose host-only network there will be no issue. have a look at the following snapshot

Cheers! Now have a look at the IP of guest machine as well.
