WebSphere Liberty is an OpenSource Project

A modern runtime for Java microservices

Over the last year we have had a lot of discussions with developers about how Liberty needs to evolve in order to meet developers’ expectations, and to continue innovating to support modern application needs. Of course, what ‘modern’ means in this context is always changing and microservices are redefining how software is developed. This is why we have been so active in the Eclipse MicroProfile project which is helping to create common APIs for writing cloud-native microservices in Java.

It isn’t just about what we do, though, it is also how we do it. Talking with developers we have often been asked if we have any plans to open source Liberty. Well the answer is yes. The open source core of WebSphere Liberty is now available on GitHub under the EPL v1 license. You can find out more and download the latest nightly builds on the new OpenLiberty.io website. We have a new mailing list on Groups.io for discussion and we will also be answering questions on Stack Overflow.

You can enable Cross Origin Resource Sharing (CORS) for your web applications on a Liberty server. Enabling CORS will allow JavaScript clients to make requests against your application on the Liberty server even if the client and the server are on two different domains. Web browsers prevent these requests due to same-origin policy. I create the following configuration on my local machine on server.xml file:

In the web server plug-in, what do the LoadBalanceWeight, MaxConnections, ConnectTimeout, ServerIOTimeout, RetryInterval, IgnoreAffinityRequests, and GetDWLMTable options mean and what are the recommended settings for these options To understand how load balancing works in the web server plug-in, see Understanding IBM HTTP Server plug-in Load Balancing in a clustered environment(http://www.ibm.com/support/docview.wss?uid=swg21219567). To understand how fail-over works in the web server plug-in, see Understanding HTTP plug-in failover in a clustered environment(http://www.ibm.com/support/docview.wss?uid=swg21219808) . LoadBalanceWeight is a starting "weight". The value is dynamically change
