Hi.

I have some problems when i try to configure my jobExecutor. I found some topics on this forum which helped me.

I have modified my activiti-explorer\WEB-INF\applicationContext.xml like this:

<?xml version="1.0" encoding="UTF-8"?>

When I start Tomcat, I have a BeanCreationException with the following message:
Could not instantiate bean class org.activiti.engine.impl.jobexecutor.JobExecutor. Is it an abastract class?

What did I do wrong?

Thanks for your help.
