Once you install the Jdeveloper 11g, you cannot Create or Open SOA projects in it. In order to use Jdeveloper 11g for SOA project development, you need to install SOA Extensions in Jdeveloper 11g.
I installed Jdeveloper 11.1.1.3.0 version and followed below steps to install the SOA extensions –
1) Open your Jdeveloper 11g and Click on Help menu and select “Check for Updates” as shown below
2) A wizard “Check for Updates” is displayed as shown below and click “Next”
3) Under ‘Search Update Centers‘, select “Oracle Fusion Middleware Products” and “Official Oracle Extensions and Updates” options as shown below & Click Next
4) You will view all the available Extensions and Updates in the wizard as shown below
5) Search for SOA from the available list as shown below
6) Select the “Oracle SOA Composite Editor 11.1.1.3.0.25.57” and click Next. Now the extension will get downloaded and installed in to your Jdeveloper 11g. You can see the progress bar as shown below
7) Once the extension is installed click “Finish“.
Now you will be able to Create or Open the SOA projects in the Jdeveloper 11g.

There is nothing mentioning “SOA” on my list. What should I do? I have JDeveloper 11g Release 2 (11.1.2.1.0).
Hi Adam,
Please make sure in Step 3, you had checked the two check boxes as shown in the screen print.

it worked on me, thanks
Important Note – This version of JDeveloper doesn’t include the SOA and WebCenter pieces – to use these components you’ll need to download Oracle JDeveloper 11.1.1.6.0.
Hi Luiz,
I had used the Jdeveloper 11.1.1.3.0 version and followed the steps mentioned above. It works fine for me. Please check once if you had missed any step.
I verified in Jdeveloper 11.1.1.6.0 version and it works well.
Thanks,
Udaya
I am using
Java(TM) Platform 1.6.0_24
Oracle IDE 11.1.2.3.39.62.76.1
I couldnt find any SOA template in my IDE. I tried all the updates but it dont seem to have the new SOA template in.
Can you please help me with this?
Thanks
What i don’t realize is if truth be told how you’re now not really
much more smartly-liked than you may be right now. You are very intelligent.
You already know therefore significantly relating to this subject, made me individually consider it from a lot of
various angles. Its like women and men aren’t involved until it is one thing to do with Woman gaga! Your own stuffs outstanding. All the time deal with it up!
I don’t even understand how I ended up here, but I assumed this submit was great. I don’t
know who you are however definitely you’re going to a famous blogger if you happen to are not already. Cheers!
