Minor Description
I was seeing a couple exceptions in different calls: * Getting the list of emails via imap
- Reading the emails via imap
- Sending emails
- Resolving the rewrite table
- even in my personal mailet
The only thing in common was the "cause" of the exception:
Caused by: java.sql.SQLNonTransientConnectionException: (conn=17) unexpected end of stream, read 0 bytes from 4 (socket was closed by server)
I found that there must be an issue with the configuration of the BasicDataSource and I saw these properties are not set and cannot be set:
basicDataSource.setTestOnBorrow(true); basicDataSource.setValidationQuery("select 1"); // Is different by database. See list here: https://stackoverflow.com/questions/10684244/dbcp-validationquery-for-different-databases basicDataSource.setValidationQueryTimeout(2);
