Closing a connection in "finally {...}"

Question

Hello!
I have a connection pool constantly growing in an OC4J in an Oracle 9iAS. My question is kind of "basic", but I need to find the "leak":
In the Handler-classes I close the resultsets, statements and connections in a finally-block, but return-values (if any) are returned in the try-block. Will the finally-block ever be executed if no exceptions are caught? Obviously that is my assumption, but I'd appreciate a confirmation or correction.
try {
Connection con = ...;
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("...");
ArrayList sampleStrings = new ArrayList();
while(rs.next()) {
String example = rs.getString(1);
sampleStrings.add(example);
return sampleStrings;
catch(...) {...}
finally {
if(rs!=null) rs.close();
if(stmt!=null) stmt.close();
if(!con.isClosed() && con!=null) con.close();
BR,

Hi Herman,
Will the finally-block ever be executed if no exceptions
are caught?Of-course it will. The "finally" block is always executed.
The OTN forums don't recognize HTML tags. Like a lot of other forum sites, the OTN forums use special tags known as UBBCode. Unfortunately, the OTN forums seem to recognize a very limited set of these tags. The only two tags which always seem to work (regardless of which Web browser I use) are:
[ url ]
[ code ]
Note: The spaces are added intentionally, so that they won't be recognized. When you use them in your post, remove the spaces.
The JavaRanch forum has a Web page that explains UBBCode.
Good Luck,
Avi.
