Creation of a connection mock-up to/from RabbitMQ

[Anonymous]

error

Hello all,

so I tryna set up a mock-up to test how RabbitMQ works.

So far I created a test route on Talend ESB.

Enclosed you can find all the properties I set in each item, but as you can see in the first pic above this text I get every time an error I don't know how to fix.

Can someone please help; I'm pretty knew to this.

Thx!

thanks,

"class not found" usually because some libraries missed (not installed or broken)

do you have installed 3rd party libraries in Studio? (menu Help)

I have similar routes on 4 machines,  work fine

Hello all,

it runs so far now, but there is an error because the syntax for the link changed.

Does someone know where I have to put the hostname and port?

because the new syntax is rabbit:exchange?[custom]

Thanks.
