"The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, "I was wrong."

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.

The Three Trees
Once there were 3 trees on a hill in the woods.
They were discussing their hopes and dreams when the first tree said, "Someday I hope to be a treasure chest. I could be filled with gold, silver and precious gems. I could be decorated with intricate carving and everyone would see the beauty."
Then the second tree said, "Someday I will be a mighty ship. I will take kings and queens across the waters and sail to the corners of the world. Everyone will feel safe in me because of the strength of my hull."
Finally the third tree said, "I want to grow to be the tallest and straightest tree in the forest. People will see me on top of the hill and look up to my branches, and think of the heavens and God and how close to them I am reaching. I will be the greatest tree of all time and people will always remember me."
After a few years of praying that their dreams would come true, a group of woodsmen came up on the trees. When one came to the first tree he said, "This looks like a strong tree, I think I should be able to sell the wood to a carpenter," and he began cutting it down. The tree was happy, because he knew that the carpenter would make him into a treasure chest.
At the second tree the woodsman said, "This looks like a strong tree, I should be able to sell it to the shipyard!" The second tree was happy because he knew he was on his way to becoming a mighty ship.
When the woodsmen came upon the third tree, the tree was frightened because he knew that if they cut him down his dreams would not come true. One of the woodsmen said, "I don't need anything special from my tree, I'll take this one," and he cut it down.
When the first tree arrived at the carpenters, he was made into a feed box for animals. He was then placed ! in a barn and filled with hay. This was not at all what he had prayed for.
The second tree was cut and made into a small fishing boat. His dreams of being a mighty ship and carrying kings had come to an end.
The third tree was cut into large pieces and left alone in the dark.
The years went by, and the trees forgot about their dreams. Then one day, a man and woman came to the barn. She gave birth and they placed the baby in the hay in the feed box that was made from the first tree. The man wished that he could have made a crib for the baby, but this manger would have to do. The tree could feel the importance of this event and knew that it had held the greatest treasure of all time.
Years later, a group of men got in the fishing boat made from the second tree. One of them was tired and went to sleep. While they were out on the water, a great storm arose and the tree didn't think it was strong enough to keep the men safe. The me! n woke the sleeping man, and He stood and said "PEACE" and the storm stopped. At this time, the tree knew that it had carried the King of Kings in its boat.
Finally, someone came and got the third tree. It was carried through the streets as the people mocked the man who was carrying it. When they came to a stop, the man was nailed to the tree and raised in the air to die at the top of a hill. When Sunday came, the tree came to realize that it was strong enough to stand at the top of the hill and be as close to God as was possible, because Jesus had been crucified on it.
The moral of this story is that when things don't seem to be going your way, always know that God has a plan for you. If you place your trust in Him, He will give you great gifts. Each of the trees got what they wanted, just not in the way they had imagined. We don't always know what God's plans are for us. We just know that His ways are not our ways, but His ways are always best.
Please keep this moving...pass it on, so He may inspire more people on the way. May your days be blessed. And until we meet again, may God cradle you in the palm of His hand
Always believe in God's works is wonderful.
