[jira] [Updated] (JAMES-2386) Data Source Pool is not validating
connections
[ https://issues.apache.org/jira/browse/JAMES-2386?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Simon Levesque updated JAMES-2386:
----------------------------------
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:
{noformat}
Caused by: java.sql.SQLNonTransientConnectionException: (conn=17) unexpected end of stream, read 0 bytes from 4 (socket was closed by server){noformat}
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:
{code:java}
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);
{code}
