Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt © Ericsson AB 2006Sao Paulo ICT-OSA/Parlay Workshop How to work with this package Use runEclipse to start the Eclipse IDE. In Eclipse there are several projects, either for Parlay or Parlay X that will illustrate a certain feature of the standard. Each exercise has a solution. Use the solution to compare your results but try your best before doing so. Each exercise will take about 30 minutes. (Some less some more). First there will be an introduction and last will be a summarization of the intended solution.
