java.io.IOException: Permission denied while federating node with addNode
While federating a node to a deployment manager of IBM WebSphere Application Server V7 I ran across the following issue: I must admit I couldn’t fix the issue right away even though the solution was indeed in the stack trace itself. The “Permission denied” part led me to think it was an issue with user [...]
Can’t dynamically bind non-dynamic var in Clojure 1.3
That’s what I enjoy the most – a series of short and concise readings in the early morning that eventually lead to a solution of a problem I could not likely have tackled successfully otherwise. I stumbled upon Hello Web : Dynamic Compojure Web Development at the REPL by John Lawrence Aspden. It took me [...]
Suppress join failure in WS-BPEL 2.0 with WebSphere Integration Developer V7
While preparing for the IBM Certified Solution Developer – WebSphere Integration Developer V6.2 certification I came across an area I’ve lately been getting into – the parallel activity. I described its main points in Running activities concurrently with flow (parallel) activity in WS-BPEL 2.0 on my blog. There’s been one thing I truly missed while [...]

The parallel activity is a structured activity so you can nest other activities – their collection – in a business process flow to have them run in parallel, concurrently. What made me think it’s more complicated [...]
Serializing reference of @Stateful session beans in EJB 3.1 with GlassFish 3.1
It’s all started with the EJB 2.1 and the javax.ejb.Handle interface. I remember I’ve always been meaning to check it out myself – how it is to save a reference of a stateful session EJB. There’s a myriad of use cases that would justify the need to figure it out – storing a @Stateful EJB [...]
ClassCastException when Untyped Component with Java interface gets its non-Java implementation
While reading about Service Component Architecture (SCA) interfaces in Interfaces of the WebSphere Enterprise Service Bus, Version 7.0 information center, I came across the following paragraph: All components have interfaces of the WSDL type. Only Java components support Java-type interfaces. If a component, import or export, has more than one interface, all interfaces must be [...]
