i am using quartz with spring, the error occured when a machine caught a job which was not built by itself. the problem is one machine stored service bean in jobdatamap, another machine could not relove the class for the bean ,because the class name add something like a hashcode.

the class name stored in thd database is correct,but when it is read out by another node ,it turns to be wrong.now ,i trace it to getobjectfromblob function of stdjdbcdelegeta class

i am undergoing a project using quartz and spring,now i am trying the cluster.there is a problem ,the job class name stored in the db is correct but when another node retrieve the job, it reported couldn't retrieve job and the reported class name is not what it is in db.in the error description,the class name add something like $$enhancerbycglib$$xxxxx,i don't know why,and how can i solve this problem.i am using quartz 1.8.4 .thx
