    UnmarshalException MySQL

    David Linsin Newbie

      Hi there,

      I wrote a SessionBean which is fetching data of an EntityBean. The data is stored in a MySQL database. The problem is from time to time an 'UnmarshalException' is thrown when I run my application which gets the SessionBean that is fetching the data of the EntityBean.

      In the JMX Console at the 'ManagedConnectionPool' for MySQL I can see that after the Exception is thrown, the ConnectionCount is 0. When I run the application a second time the ConnectionCount is 1 and I get my data.

      What do you guys think is the problem?
