Question

I have an sql query in my controller action (select * from table….where…..et al). This query is fired when the user submits a page.

It is a 50 lines code that takes in 3 parameters.
For eg: select * from employee where empDate=’params.empDt’ and empNum=params.empNum order by params.sort asc.

In the above case the query takes in 3 parameters (params.empDt, params.empNum and params.sort) dynamically and is executed.
Since it is a huge query, I am looking at externalising the query to an sql file. The file thus externalised would be called in the service and the query would be executed.

So i created the .sql file in grails-app/conf/sql/read_date.sql.

When i read this file and the run the app, using run-app, it wrks fine. I am able to read the file and execute the query.

However, when I create a war and deploy it on tomcat, the appn doesnt read the file and I get a FileNotFound Exception.

java.io.FileNotFoundException: grails-app/conf/sql/read_date.sql (No such file or directory)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.(FileInputStream.java:106)

Inputs??

Well you see the thing is, the grails-app/conf structure does not exist within the war. If you use something like 7-zip to open up the war and take a look around in it, you will see that all the Classes in conf are now in Web-Inf/classes. The directory structure is only really guaranteed through development. If you created an Sql file in web-app/sql, this might solve the problem for you as the directories under web-app are respected during War generation. Web-app contains thing like javascript files that are required by the application and are then accessible via http://myhost:port/AppName/sql/my.sql. If I were you, I would database the sql though.

Hope this helps.
