I am using the following java option for my tomcat instance:
-Dhttps.proxyHost=myproxy.server.com
-Dhttps.proxyPort=3128
-Dhttp.proxyHost=myproxy.server.com
-Dhttp.proxyPort=3128
While my application is able to connect to http://example.com:80 , it won't connect to any socket except for 80 and 443.
I was wondering if there is a special option for granting the proxy access for other custom ports as well.
Update: Stacktrace added below:

Add the jar somewhere such that eclipse can find it and use the driver from the jar to connect to the database. Refer the below screenshot which might be helpful to you. Otherwise you can always add it to your projects classpath.
Below is the graphical way to do it.

It seems you are still trying to write something to response. Can you add a return statement after the redirect.
response.sendRedirect((“home.jsp”));
return;
i solved this issue by using javascript window.location instead of send Redirect
window.location="home.jsp";
