Cannot Integrated JDeveloper with SOA Server

When trying to integrated JDeveloper with SOA server the below error Appeared :-

Testing JSR-160 Runtime … failed.
Cannot establish connection.
Testing JSR-160 DomainRuntime … skipped.
Testing JSR-88 … skipped.
Testing JSR-88-LOCAL … skipped.
Testing JNDI … skipped.
Testing JSR-160 Edit … skipped.
Testing HTTP … success.
Testing Server MBeans Model … skipped.

all my searching on internet not working most of the blogs indicate it’s proxy setting which is already disables in my case.

After invesgtation and check logs on the both side adminserver and Jdeveloper i found it’s DNS server issue therefore i edited hosts in windows like the below

Adminserver-IP   Hostname

After do this and put hostname instead of IP it’s worked Successfully.
