Re: Java DSL route now needs a MS SQL .to( How do I declare connection info?


Hi

You have set the datasource already on the sql component, so in your
Camel sql endpoint you should not have ?dataSource=#xxxx - that can be
removed

>>> I've been looking for examples of how to declare the servername/instance name, username password to utilize a MS SQL endpoint.  Looking at the Apache Camel: SQL Component page, it shows utilizing  the declared object like "mydbconnection" that is the named DataSource option, and shows all on what you can throw through that connection... except seems to skip over how to specify connection criteria.  It does reference the DataSource option as a pointer to look up in the "registry" but I don't know if that is an inherited existing entity it's talking about or the need to declare a new registry and import a form of camel registry or something.  The only examples where I've seen servername, un/pw declared in an example was in a Spring one.  I don't know if we want to "un-translate" a Spring example, but point me in the direction of where I should natively set these things in Java DSL.  The above mentioned page even says "This component uses spring-jdbc behind the scenes for the actual SQL handling", so I figured that is why I cannot seem to get away from Spring.
>>> When I look at the Apache Camel: SQL Example( http://camel.apache.org/sql-example.html <http://camel.apache.org/sql-example.html> )  page, it talks about "In the camel-context.xml file in the src/main/resources/META-INF/spring folder we have the Spring XML file to setup and configure the database"

I have been attempting to utilizing the JDBC endpoint provided though camel-sql.. but I cannot seem to either find documentation of how to place a configuration file with an unknown name in an unknown location in the project, or declare it in-line.  Been looking at setting it first in the "camel registry", but no luck so far.

I'm not to the point I need to form any sort of SQL statement yet, since I cannot establish a connection.It seems so simple, but I cannot find how to simply declare server:port, un/pw without bringing a Spring context into the mix.  If that is needed to satisfy the camel vanilla SQL endpoint needs, how do I tie that into the Java DSL route I've already got going?  I went the Java DSL route simply because some other endpoints didn't have a straight forward Camel Spring solution to them.  Is this mixed environment normal?  Is there really not a choice to keep a route "clean" in one coding style or the other?
