While developing and evolving a REST API, using Java EE, there are some cases where you would like to have a look on the incoming HTTP request, specifically the header params, in a more fine grained (per case) way, rather than a Servlet Filter or the more specific ContainerRequestFilters . One potential way, which I …

Lately, I have been considering using Swagger (core and it's related maven plugin) for one project, in order to provide some REST API documentation. Despite the fact, that Swagger is indeed a very powerful library, doable to integrate on your JAXRS 2.0 code base and the maven plugin works at the end of the day I think …

Personal note to me rather than something special, if you use Boot2Docker on your MacOSX and you want an easy way to your docker command line client to connect to the underlying boot2docker vm, add on your /.bash_profile_ file the following line.

Actually is the simplest. It offers a single download for many platforms (including MacOSX). You can find them here. It …

In this post we will install on our local MacOSX (Yosemite) environment, another famous NoSQL database, the Apache Cassandra. As a developer, I found Datastax, community packaging of Cassandra, very handy, seems they offer ready made MacOSX specific packages. You can of course download and install the the tarballs f …

This post aims to help all developers (not only Java) that want to develop using NoSQL datastores, specifically MongoDB, Cassandra and Couchbase, in MaOSX. Before starting writing code you need to have the db engines installed and ready for tests. So our goal for these mini posts will be to install all of them in our …

Like many of you out there, I am working with a multi module Maven project. It is not a huge one comparing to many systems out there, it has 15 modules, with 3 different ear deployments, lots of parametrization with property files and around 100K lines of Java code. During peak development times, the code is heavily …

This is not something I invented or discovered on my own, with this post I just want to raise the awareness of this major missing point IMHO in standard Websphere 8.5.5 configuration (and it's fix) and post about it, so it can be indexed and people can find the solution easily, rather than spend countless hours trying …
