Are multiple calls to java SaxParser.parse(String, Handler) Legal?

I have a java SAX parser which I would like to call multiple times on the same Handler with different XML files. I am using this in conjunction with iText to create a multi-page PDF document where some pages have one XML tag map and other pages have another. For example,

parser.parse("xmlFile1", handler);
parser.parse("xmlFile2", handler);

When I try to do this, I get a java.lang.RuntimeException thrown with the following stacktrace:

DocumentException: java.lang.RuntimeException: The document is not open.

Does the SaxParser.parse method implicitly call document.close()? Or is there some other problem in my code which I need to isolate and correct?

• Reusing the same parser is legal (as long as it is not used concurrently)
• The parser triggers an "endDocument". This seems to close the iText document here.. But this is not done by the parser - this is code from your handler.
