Subject [jira] [Closed] (DBCP-362) Cannot create PoolableConnectionFactory when system proxy is defined.
Date Mon, 30 May 2011 10:38:47 GMT

     [ https://issues.apache.org/jira/browse/DBCP-362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karol Krzyzak closed DBCP-362.
------------------------------

    Resolution: Not A Problem

The problem stemmed from the use of SAF (Simple Application Framework). Spring initialization
has been performed in method initialize a proxy definition in the method main. After the transfer
the following line of code to the initialize method, application start normally.
Code:

System.setProperty("java.net.useSystemProxies","false");

> I was based on the information contained in article "Java Networking and Proxies" (javase/6/docs/technotes/guides/net)
> I turn off using proxy.
> I think for some reason the JRE tries to talk SOCKS protocol to a host, which is not
a SOCKS proxy.
> For clearly, I haven't SOCKS proxy server.
> Still debuging....
> (BasicDataSource.java)
> It hangs in method protected static void validateConnectionFactory(PoolableConnectionFactor
y connectionFactory) when try to call conn = (Connection) connectionFactory.makeObject();
> and as I mentioned after 5minutes throw above exception.
