tomcat中报错
Not binding factory to JNDI, no JNDI name configured
2008-5-26 17:06:40 org.jbpm.job.executor.JobExecutorThread run
严重: exception in job executor thread. waiting 5000 milliseconds
java.lang.UnsupportedOperationException: The user must supply a JDBC connection
at org.hibernate.connection.UserSuppliedConnectionProvider.getConnection(UserSuppliedConnectionProvider.java:30)

为什么我的文件都mapping上了还抱错，网上说是hibernate.properties和hibernate.cfg.xml的问题 我试了还是报错

tomcat6 jdk1.6-01
