Re: Intermittently java.lang.NoClassDefFoundError

Hi

Do you deploy a war, an ear? Where is the driver,  in tomee/lib?

I would be curious to know which thread causes it and the full stack trace
- configuring log pattern you should be able to get it.

In all cases try to not put your drivers in webapps if you can.

Thanks for responding.  

The application is deployed as a war.  It is deployed as root.  

The sql driver is in both the tomee/lib and in
tomee/webapps/ROOT/WEB-INF/lib/.  I tried removing the jar from 
tomee/webapps/ROOT/WEB-INF/lib/ and I get the same results.  This seems to
be a redeploy issue.  If I reboot the server I don't get this issue.  Well
at least not in the last 5 days.  

My tomee.xml is:

 <Resource id="sql-server-ds" type="DataSource">
    JdbcDriver = com.microsoft.sqlserver.jdbc.SQLServerDriver
    JdbcUrl = jdbc:sqlserver://10.10.2.120:1433;database=app;
    UserName = user
    Password = pasword
    TestOnBorrow=true
    ValidationQuery= select 1
    MaxActive = 1000
    MinIdle = 10
    RemoveAbandoned = true
    ValidationInterval = 30000
    SuspectTimeout = 60
    TimeBetweenEvictionRunsMillis = 30000
    MinEvictableIdleTimeMillis = 60000

</Resource>
