will java 1.3 support these APIs

Hi,
I am using javax.xml.parsers.DocumentBuilder ,

javax.xml.parsers.DocumentBuilderFactory and org.xml.* and org.w3c.* in my code will

java 1.3 support this or not.

Thanks in advance.

Read the API doc to see when those classes were added to java.
Get a 1.3 compiler and try to compile a program that uses those APIs

I believe it will but there is only one way to find out for sure..

Don't think so....the API for these packages should have a 'since' value - just looking at the org.w3c.dom.* docs shows this package has been available since 1.4 As norm suggested, I recommend you check the 'since' value for other packages you are interested
