Subject Re: [DRDA] Question about DRDAStatement.initialize() method
Date Fri, 24 Feb 2006 00:15:26 GMT
Thanks Knut and Kathey. I will open a jira issue for changing use of
initialize or do it in a separate patch. For your answers to
question3, I have a small concern. Please see below.

pkgnamcsn is the key used for statements added to stmtTable. It seems
to the basis for reusing statements. Resetting it seems a bit odd to
me. Code in Database.newDRDAStatement will look like this:

                DRDAStatement stmt = getDRDAStatement(pkgnamcsn);
		if (stmt != null) {

Do you think it is okay?
