Subject [jira] Updated: (AMQNET-135) Error in parsing composite Uri on Linux Mono
Date Fri, 06 Feb 2009 21:53:59 GMT

     [ https://issues.apache.org/activemq/browse/AMQNET-135?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Allan Schrum updated AMQNET-135:
--------------------------------

    Attachment: AMQNET-135-741308.diff

After checking into the code change required, I think it is a simple case of reprocessing
the original URI that is passed. Before, the System.Uri.AbsoluteUri was used to reprocess
the composite URI. This modification uses System.Uri.OriginalString if not .NET 1.0 or 1.1.
Thus we should avoid the Mono problem (bug?) that changes double slashes into single slashes
since we are using the original string and not the processed string.

Can you please test and let us know if this works? This patch also includes to patch to AMQNET-140.

> I'm using ActiveMQ .Net to connect to ActiveMQ from Mono application on linux.
> I've downloaded new (12-12-2008, rev. 726083) version of ActiveMQ .Net and started from
testing new feature: FAILOVER transport.
> First test made on Windows were very promising, but trying to run my application on linux
caused an error.
> I've invested it a bit and found out this:
> On linux Mono the System.Uri constructor causes error while parsing composite uri, because
it replaces all '//' with '/'. And tries to connect to 'tcp:/localhost:61616' for example.
> I've tested it on newest Mono 2.0 SUSE with the same result.
> Uris, I've tried:
> failover:(tcp://192.168.44.244:61616)
> failover:(tcp://192.168.44.244:61616)/
> failover://localhost/(tcp://192.168.44.244:61616)

+ "'");
