Hi All,
I have a query related to application implementation.
We have an application where we load 3 schemas into
memory. Now we want to validate 3 different kinds of
xmls at run time with appropriate XML Schema.
In short our application is multithreaded application.
Currently for each request we create NEW instances of
DocumentBuilderFactory and DocumentBuilder:
DocumentBuilderFactory.newInstance();
DocumentBuilder builder =
factory.newDocumentBuilder();
Document document = builder.parse(xml String);
With All Schema's cached as a File objects in
Singleton class.
My question to all of you is:
Is it absolutely required to create an instances of
"DocumentBuilderFactory and DocumentBuilder" for each
request? [as it is performance hit]
Is there any way we can create application-wide, 3
instances of DocumentBuilder ,initially and re-use
them for all further validation requests for "xml
String" ?
I guess even synchronization can be performance hit.
Please advise me.
Thanks a lot for your help /Vikrant
