Java Mail using Java Thread For better performance | Oracle ADF

Hi,

Today i decided to show New Challenge and How to fix specially when we are speaking about Tuning Options in Java / ADF Applications.




While Building MEITS E-Portal | Middle East Information Technology Services, we discovered one issue related to JavaMail Performance, we are using Standard JavaMail to Send Emails from MEITS Domain, but the problem is, it takes about 15sec to send and receive a confirmation.

I Think this is Normal as we are using Low Level of Security in Google Security Rules and may Google try to put our Requests under some Security / Verification before Sending Emails.


We tried to improve Java Mail Code, but no Change in performance, and so we tried to improve Email Sending Process using Java Threads as it is independent of our main Process and then we can convert Single Thread Process to Multiple Thread Process.





Any Now,  our Main Process takes Less than 1sec and Sending Mail Process is working in Background.

Regards !

Oracle ADF | SMS issue : javax.net.ssl.SSLHandshakeException: Server chose TLSv1

Hi,

While Building our New Baby Oracle ADF MEITS E Portal (Middle East Information Technology Services) will be published at beginning of September 2015 to Serve IT Developers / Companies in Middle East, we faced one issue Related to Sending SMS Messages using BulkSMS Services to International Clients.

 
 


The problem is, Application is working fine in Development Stage / but After the deployment we face TLSv1 Protocol issue in Weblogic 12.* JDK 8.

Solution is : TLS Protocols are not working by Default in Weblogic by Starting Admin or Managed Servers, you have enhance your startup scripts to include such protocols while starting up or start all by using this Parameter.

-Dweblogic.security.SSL.protocolVersion=ALL

Note : No Need to make any changes in SSL Configurations in Weblogic, we tried before but no luck.

Now you can Enjoy SMS Services in your Oracle ADF Application !

javax.net.ssl.SSLHandshakeException: Server chose TLSv1, but that protocol version is not enabled or not supported by the client.
