Subject: Re: [xsl] xalan-j2 D7: StreamSource cannot be kept? From: "Robert Koberg" <rob@xxxxxxxxxx> Date: Thu, 9 Aug 2001 12:43:54 -0700 |
I am looking but I don't see how to close the StreamSource. I am setting it to null but that does not help. In the examples I always see something like: Templates templates = tfactory.newTemplates(new StreamSource(xslID)); I assume that by doing it this way the StreamSource gets closed automatically? How would I close the stream if I created the "new StreamSource(xsl)" somewhere else? thanks for the help, -Rob ----- Original Message ----- From: <Myriam_Midy@xxxxxxxxx> To: <xsl-list@xxxxxxxxxxxxxxxxxxxxxx> Sent: Thursday, August 09, 2001 12:03 PM Subject: Re: [xsl] xalan-j2 D7: StreamSource cannot be kept? > > Robert, > Users are responsible for closing streams in Xalan.
