Passing Database Pool Connection to Java Object

Question

SO I have a set of Java libs that i would like to use within
CFMX. In fact, I would like to do all my business logic with those
libraries. Question is, the classes require I pass a database
connection to them. How would I do this?

Answer 1

In Coldfusion you can just code the usual Java DB connection
directly. That is, something like
<cfscript>
classObj = CreateObject("java", "java.lang.Class");
classObj.forName("etc.etc..Driver");
driverManager = CreateObject("java",
"java.sql.DriverManager");
connectionURL="jdbc: etc etc. ";
conn=driverManager.getConnection(connectionURL,username,password);
myQuery="SELECT blah1, blah2 FROM blah3";
preparedStatement = conn.prepareStatement(myQuery);
rs=preparedStatement.executeQuery();
while (rs.next()) {
etc etc
rs.close();
conn.close();
</cfscript>
That is for single calls. To set up a permanent connection,
you could include in the libraries a class whose job is simply to
establish the connection to the DB. I should expect the code to
contain some of the themes above, namely,
getConnection (String url, String user, String password)
connectionURL = "jdbc:etc"
java.sql.Connection conn =
java.sql.DriverManager.getConnection (connectionURL, username,
password);
etc. etc.
You could also find it convenient to store connection and
user data data in a properties object of the java.util.Properties
class.
java.util.Properties properties = new java.util.Properties
properties.setProperty ("user", "bkbk");
properties.setProperty ("password", "knoflook");
java.sql.Connection conn =
java.sql.DriverManager.getConnection (connectionURL, properties);
