Dear all,
Solved the issue as follows:
1. Set the Facade as transient
private transient ISaveFacade saveFacade;
2. In the get method, check if the facade is null. If it is null, then call
the reset method;
3. Add new reset method as follows:
private void resetFacade() {
ClassPathXmlApplicationContext ctx = new
ClassPathXmlApplicationContext("/config/spring-persistence-runtime.xml");
setSaveFacade((ISaveFacade) ctx.getBean("saveFacade"));
}
Note: I had an issue using the spring persistence configuration I use for
running the application, so I created a different one for the Bolts.
Hope this helps.
Regards
Joseph
