I get a java.lang.NullPointerException when i do this ?

try {doc = parser.parse(xmlText);}
catch (SAXException ex){out.println(" <error>"+ex+"</error>\n");}

Debugger or compiler doesn't give me any warnings or anything ?


Why do i always get a 500 response ?

try {doc = parser.parse(new InputSource(in));}
catch (SAXException ex){out.println(" <error>"+ex+"</error>\n");}

What is on line 37 of query.java?

BTW, Class names (and therefor .java files) should always start with a
capitol case letter. "Query" would then be appropriate.

Make sure that "parser" is an actual value, and not just null. You
need to get it from the
DocumentBuilderFactory().newInstance().newDocumentBuilder()
