public static Integer getTomcatPortFromConfigXml(File serverXml) {
Integer port;
try {
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true); // never forget this!
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse(serverXml);
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
XPathExpression expr = xpath.compile("/Server/Service[@name='Catalina']/Connector[count(@scheme)=0]/@port[1]");
String result = (String) expr.evaluate(doc, XPathConstants.STRING);
port = result != null && result.length() > 0 ? Integer.valueOf(result) : null;
} catch (Exception e) {
port = null;
}
return port;
}
