Execute simple SQL query on Java

Question

Hello,
I am a newbie on ADF, I am a web developer used to work with EJBs, WebServices, Servlets and this stuff... But now I am on a project that uses ADF.
My opinion, I don´t like this kind of development, drag and drop, I prefer to code on :) but, I need to work.
I am developing a utility class that needs to run some SQL statements and send an email.
I tried to work with the conventional @Resource (name...) Datasource ds; and did not worked, because it does not injected the object.
I tried to create a java implementation of my application module, instanciate it and get a ViewObject that I created to do a select statement, and the ViewObject comes null...
I just wanna do a simple query... just it, using simple java for web I would have already done it... How is the best way to do it?
Thanks.

ApplicationModuleImpl am = getApplicationModuleByName("AppModuleDataControl")
DBTransaction dbt = am.getDBTransaction();
CallableStatement cs = dbt.createCallableStatement(query, .......
You can get ApplicationModule by this code. In this case there should be some binding related to this AM in pageDef. Input parameter "name" should be datacontrol name;
public static ApplicationModuleImpl getApplicationModuleByName(String name) {
try {
BindingContext bc = (BindingContext)resolveExpression("#{data}");
DCDataControl dc = bc.findDataControl(name);
return (ApplicationModuleImpl)dc.getDataProvider();
} catch (Exception e) {
l.error(e);
return null;
public static Object resolveExpression(String expression) {
l.debug("expression: " + expression);
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
ExpressionFactory exprFactory =
fctx.getApplication().getExpressionFactory();
ValueExpression ve =
exprFactory.createValueExpression(elctx, expression, Object.class);
Object value = ve.getValue(elctx);
return value;
}
