How to close DB Connections while shutting down server
Dear Experts, I am using container managed datasource to manage the database connections. But while shutting down the server I am getting lot of messages like below: appears to have started a thread named [pool-1-thread-1] but has failed to stop it. This is very likely to create a memory leak Would you please suggest any better way so that open connections in Pool will be gracefully closed while shutting down the application. Thank you very much Regards, Rajesh
Re: Intermittent handshake_failure message Tomcat
I am using java version JDK 1.7.0_51. I have java client running in Linux X64 platform. Both the commands which you provided are working perfectly for me. As I mention in my previous mail, the problem is intermittent.

Re: Facing SSL Exception in Tomcat 7.57 using Java
Thanks for your support and suggestion, the client code will be distributed to many clients as command line interface, so changing the JDK with 1.7 will take time and effort. I found the way to set the SSL property in JDK6 and JDK5, after the below changes code is working fine: System.setProperty( "https.protocols", "TLSv1" ); Hope it will work for any OS and any JDK greater than 1.5 Regards, Rajesh On Tue, Jan 20, 2015 at 9:17 AM, Caldarale, Charles R < chuck.caldar...@unisys.com> wrote: > > From: Rajesh Biswas [mailto:rajesh...@gmail.com] > > Subject: Re: Facing SSL Exception in Tomcat 7.57 using Java > > > Would you please pin point the issue why it is not working in JDK5, where > > can I set the TLS property. > > Note that JRE/JDK 5 has not been supported in some years; the last public > release was in October 2009.

Re: Facing SSL Exception in Tomcat 7.57 using Java
Hello Mark, I have some more points to mention. The SSL is not working from my Java client which is ran on JDK5, but same is working on JDK7. I put some debug statement to print the SSL version client is running. For JDK I am getting NONE, for JDK7 I am getting TLSv1 Below is my statement: SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault(); SSLSocket socket = (SSLSocket)factory.createSocket(url.getHost(), 4743); System.out.println( socket.getSession().getProtocol()); When I am running on JDK5 I am getting output as NONE When I am running on JDK7 I am getting output as TLSv1 Would you please pin point the issue why it is not working in JDK5, where can I set the TLS property.
