In Flux, we have made improvements in recent versions to handle database or network failures and recover from such failures gracefully without needing to restart Flux. Sometimes, it would be nice to notify administrators about these failures and they can act upon them in case of an unscheduled outage. Flux is dependent on the database … Read moreHandling Flux Database outages using BoneCP Connection Pool
Try-with-resources (originally known as Automatic Resource Management) is one of the Project Coin proposals that made its way into recent JDK 7 builds.

JAXB is the defacto OXM binding framework for the Java platform which performs marshalling (serializing Java to XML) and unmarshalling (deserializing XML to Java) using the standard Java APIs. I must admit that JAXB is a smart addition to the Java Web services technologies stack. It reminds me of days where I used to write … Read moreHate JAXB annotations: MOXy and JAXBIntroductions comes to the rescue
It is quite possible many developers have run into this problem with Jersey, not really a problem, but limitations of a programming language. I remember from school days where C++ Templates had quite a few reference books and it always kept me away from using STL containers 🙂 In Java, we have Generics since 1.5 … Read moreHandling Generified Collections in Jersey JAX-RS
I recently came across this interesting question on Job Scheduling in Java in the widely popular experts-exchange website. Unfortunately, you require subscription to see “expert” answers, unlike Stack Overflow. Here is my take on this FAQ: 1) Is it possible to use Sun’s own java.util.TimerTask for my complex report scheduling? Timer facility has limited capabilities … Read moreJob Scheduling in Java, why Flux?
Last week, I migrated the tutorial “Developing a loan processing application using Apache CXF & JPA in NetBeans” from NetBeans wiki to Google Sites. The NetBeans wiki migration late last year screwed up the contents of both the tutorials that I had contributed to NetBeans. Considering the future of NetBeans infrastructure, I decided to move … Read moreCXF + JPA Tutorial moved to Google Sites
JAX-RS runtime allows applications to supply entity providers which maps services between representations (via @Produces and @Consumes) and their Java types. The entity provider interfaces MessageBodyReader and MessageBodyWriter defines the contract that supports the conversion of a stream to a Java type and vice versa. Lets write a simple JAXRS provider for handling a SOAPMessage … Read moreSOAP over RESTy Client
SSL enabled RESTful services are quite easier to develop and test using Jersey, Grizzly and RestTemplate. Jersey (resource development) Grizzly Web Server (resource configuration and deployment) Spring 3 RestTemplate backed by Commons HTTP Client (resource access) In a moment, you will notice how all these nicely fit the bill. Let us start with the POM … Read moreAccessing RESTful services configured with SSL using RestTemplate
The central API for accessing RESTful services in Spring 3 is RestTemplate. It is like any other template mechanism provided by Spring for the client side access. The default implementation uses the java.net package for creating HTTP requests. RestTemplate can be backed by Commons HttpClient using ClientHttpRequestFactory. Using Commons HttpClient as the backend implementation supports … Read moreRestTemplate, the Spring way of accessing RESTful services
