[JTrac-users] Login error

[Mohamed L. <ml...@qu...>]

*Hello every one,

I use JTRAC and I have adjusted it to work with MySQL. When logging on 
**JTRAC** it gives an error occasionally, I noticed that this error 
occurs when we don't use **JTRAC** for some period, it seems that the 
connection to database is automatically lost, I don't know why!, when I 
restart the tomcat server it works good.

The following is the error message*
"Hibernate operation: could not execute query; uncategorized 
SQLException for SQL [select this_.id as id3_1_, this_.type as type3_1_,
