OSLC with Javascript…inside the CLM Web

Javascript surprise my every day…the last week  (inspired by the  OSLC Post from Stephane)  I played around with OSLC together with Javascript. I expected obstacles and thought that OSLC is dedicated to Java. Oh boy, I was wrong! Compare the “getCatalog” function below with the Java OSCL examples available at htttp://… Attached is an example […]

As you already know …the Open Social Widget are so useful to extend the CLM Webinterface without any hacks or quirks. Today we will use sgvizler to visualise the results of CLM SPARQL queries. What me still really surprise is how less Javsscript code is necessary to create meaningful information. Some Screen dumps… For this […]


JMX Monitoring of a CLM Tomcat Server only with the CLM Webinterface

[Update: Source Code now with Garbage collector] Sometimes it is necessary to tackle down CLM performance issues. To monitor the OS resources like CPU, IO, Memory etc. is not really helpful, because Java is like a black box for an OS like LINUX. With JMX you can look “behind the scene”. You can monitor the Heap, […]


Part1: Oauth 1.0A, NodeJS and Rational Team Concert OSLC

Today we will talk about Oauth 1.0A and Rational Team Concert. The idea is to access from a NodeJS App the artefacts from Rational Team Concert (RTC) and also from other Jazz Tools (CLM). The combination of CLM “Big Data” and NodeJS are unlimited and would open a lot of possibilities. But step by step… BTW, I’m […]
