:'''Little about me: '''Hello folks! My name is Jatinder Singh. I am a full time student at Seneca College of Applied Arts and Technology, graduating in May 2009 with a Bachelor’s degree in Software Development. What do I enjoy? Well, I am getting into photography and learning various photography techniques from online tutorials and youtube videos available on World Wide Web. I love playing sports and specially Cricket because I grew up with this game. I also enjoy working out and hope to get my abs in three to four years of time.
:'''Other things that I am doing: ''' As I am graduating this year, so I am also searching for a full-time job.

=== Week 1 ===
* Unzipped Eclipse WTP and Eclipse for RCP/Plug-in Developers on my laptop and USB key for portability
* Set up Zenit Wiki page, Blog and Account on Bugzilla website
=== Week 2 ===
* Installed Eclipse Communication Framework (ECF) to run IRC within Eclipse WTP
* Reproduced bug [https://bugs.eclipse.org/bugs/show_bug.cgi?id=173912#c0 173912] on Windows Vista Business OS without any problems
* Conducted research on Ecipse WTP - Web Services bugs to create a list of bugs that I'll be working on
=== Week 3 ===
* Reproduced bug [https://bugs.eclipse.org/bugs/show_bug.cgi?id=203257#c0 203257] on Windows Vista Business OS
* Tried to reproduce bug [https://bugs.eclipse.org/bugs/show_bug.cgi?id=142301#c0 142301] but couldn't do it due to lack of documentation
=== Week 4 ===
* Downloaded and debugged org.eclipse.wst.wsdl.ui package to find problems
* Used Eclipse tutorial (guided by Jordan) to learn about Eclipse debugging techniques
=== Week 5 ===
* Found that the org.eclipse.wst.wsdl.ui package links to source code present in org.elicpse.wst.wsdl package.
* Downloaded org.eclipse.wst.wsdl package to perform debugging and understand flow of logic through different classes
=== Week 6 ===
* Contributed to Anthony's Bit torrent project. Helped him to install Bit torrent tracker for his project (requested by Dave Humphrey)
* Read tutorials about WSDL and DOM to refresh knowledge
=== Week 7 ===
* Contribution - Helped Sid to set up Eclipse WTP and taught basic functionality
* Found the problem in my bug: reconcileReferences(boolean) method, references are lost before the code gets to this method
=== Week 8 ===
* Debugged the whole WSDL file and learned different things including: WSDL is built using DOM, DOM uses recursion to build child nodes, each node is a different Class and uses the following name format <WSDL_ELEMENT_NAME>+<Impl> e.g PortImpl

==== Description ====
:Prefix was not changed throughout whole WSDL. When I'm editing the target namespace, the links between the WSDL components are broken (for example binding A references port type B).
:'''Build ID''': M20070905-1045
:Steps To Reproduce:
:*1) Open a properties tab of any WSDL
:*2) Change the prefix name
:If there were any references to the prefix in the WSDL, they will not have been changed. In the [https://bugs.eclipse.org/bugs/attachment.cgi?id=78305 '''attached WSDL'''], the prefix was changed from "pos" to "posCHANGED" only in the namespace definitions section.

==== Comment from [mailto:wuamy@ca.ibm.com Amy Wu] ====
: '''The gorey details''':
:In W11EditNamespacesCommand#execute, the prefix is updated by removing the old namespace attribute and then adding the new one.
:Removing the old attribute will eventually trigger a reconcile on the definition.
:For Port, Binding, Message, WSDLElement#reconcileReferences() looks something like this:
:''QName messageQName = createQName(definition,element.getAttribute(WSDLConstants.MESSAGE_ATTRIBUTE), element);''
:''Message newMessage = messageQName != null ? (Message)definition.getMessage(messageQName) : null;''
:''if (newMessage != getEMessage())''
:''{''
:'' setEMessage(newMessage);''
:''}''
:The problem here is that ''messageQName'' will be null. This is because when trying to create the ''QName'' for the current referenced message, it will return null. It is null because the prefix/namespace attribute has already been deleted, so when it tries to create a new ''QName'' by looking up the prefix, it will find that there is none. So ''QName=null'' which means ''newMessage'' is ''null''. Which means ''newMessage != message'' currently referenced. Which means it will delete the message currently referenced.
:So that's how the references are lost.
:So it looks like a fix needs to be made somewhere around here to not lose the existing references.
: Once this is fixed, the next step to update the references is actually not that bad according to what is being done XSD's ''UpdateNamespaceInformationCommand''. What XSD does is it calls ''schema.updateElement()'' and that will update all the references magically. I'm assuming it does some magic with resolving the prefix/namespaces. The same type of call would need to be made in ''W11EditNamespacesCommand'' for the definition object. (See ''UpdateNamespaceInformationCommand#updateElement()'' for more details).
