Set the timeout to 0 if you want each request to be in-line with the actual database state, to Long.MAX_VALUE in order to make it work basically in-memory, or to an intermediate value to make requests cached allowing at the same time to keep it in-line with a changing database.<P><P><DL><DT><B>Author:</B></DT> <DD>wolf</DD><DT><B>Module:</B></DT><DD><CODE><B>module/main</B></CODE> (<A
