If you are connecting a Java application to a SQL Server database, which is up and running, but your connection fails with the following error:

Could not acquire a connection from DataSource – Cannot create PoolableConnectionFactory

The error is most likely that the windows service “SQL Server Browser” is disabled.

To fix the problem:

  • Start -> Control Panel -> Systems & Security -> Administrative tools -> Services
  • SQL Server Browser -> right click -> properties

  • Set Startup type to “Automatic”
  • Apply -> Start

Now you should be able to connect to SQL Server from your Java application!


IIS – Setup IIS as a proxy to Jetty

On my current project we are working on two applications for a customer, one is in .NET and the other is in Java. The client only wants to have port 80 and 443 open on the server, however, we will need to have two web servers running, IIS for the .NET application and Jetty for the Java application. Our solution was to run the .NET application on IIS on port 80 and the Java application on Jetty on port 81, then have IIS route traffic for the Java application coming in on port 80 to port 81 using IIS as a proxy to Jetty. The following is a simple tutorial on how to setup IIS as a proxy to Jetty.

Install Application Request Routing (ARR)

Setup IIS to Jetty Redirect

For this example the route for the Jetty application will be “fddapi”.

Open IIS and on the Server¬†select “Application Request Routing” icon.


Select “Server Proxy Settings”.


Set “Enable Proxy” setting and “Apply” the change.


Go to “Default Web Site”, select “URL Rewrite”.

4-Select Url ReWrite

Under the Actions menu select “Add Rules”.


Under “Inbound Rules” select “Blank Rule” and click “Ok”.


Edit the Inbound Rule with a pattern to match on and how to rewrite the url.


Test the Setup

Now open a browser and go to the url: http://localhost/fddapi/someroute which should work now without needing to specify port 8081.
