How to crack the SCDJWS ?..

The wikipedia says SCDJWS is the toughest and the most respected Sun Certification.
http://en.wikipedia.org/wiki/Sun_Certified_Professional#Sun_Certified_Developer_for_Java_Web_Services_.28SCDJWS.29
Very true indeed.

I scored 79% (55/69). Here's the split up.

XML Web Service Standards 80%
SOAP 1.1 Web Service Standards 83%
Describing and Publishing (WSDL and UDDI) 100%
JAX-RPC 85%
SOAP and XML Processing APIs (JAXP, JAXB and SAAJ) 100%
JAXR 75%
J2EE Web Services 71%
Security 75%
Developing Web Services 66%
General Design and Architecture 50%
Endpoint Design and Architecture 80%

Preparation Plan

1. RMH Book for XML Basics, Namespaces, Schemas, SOAP, WSDL
2. Rest of the chapters - MZ notes. - javaboot
3. xyzws.com mock exams

The questions in the real exam were little tough than xyzws mocks. It wasn't that straight forward, but with little thinking it can be answered.

I did practise a little with all the APIs. I hosted a Web Service using JAX-RPC, wrote some schemas and compiled it. I used the tomcat for java web services developer pack.

CSV Parser in Java

public class CSVParser {

public static final String CSV_REGEX_PATTERN = "\"([^\"]+?)\",?([^,]+),?,";
public static final String TSV_REGEX_PATTERN = "\t{1}";
public static Pattern csvRE;
public static Pattern tsvRE;

static {
csvRE = Pattern.compile(CSV_REGEX_PATTERN);
tsvRE = Pattern.compile(TSV_REGEX_PATTERN);
}

private List parse(String line) {

List list = new ArrayList();
Matcher m = csvRE.matcher(line);

// For each field
while (m.find()) {
String match = m.group();
if (match == null)
break;
//this will remove trailing , - comment this out if we dont want that affect
if (match.endsWith(",")) {
match = match.substring(0, match.length() - 1);
}
if (match.startsWith("\"")) {
match = match.substring(1, match.length () - 1);
}
if (match.length() == 0)
match = null;
list.add(match);
}

return list;
}

}
