These days I'm working with Java, Swing & AWT. An interesting move from web development. Now I can catch many errors at runtime and Java usually points to where the problem is, except for this exception I came across recently: Uncaught error fetching image: java.lang.NullPointerException at sun.awt.image.URLImageSource.getConnection(URLImageSource.java:97) at

I had some bash scripts to write a little while ago and I thought I'd share them here. Let's start with a simple task. Say we have a load of files in a directory, e.g. null121231.xml, null3049432.xml etc. and we want to remove null from the start of the files' names: for f in null*; do mv "$f" "${f#null}"; done Moving onto a little more complex. I wanted to write a script that would backup

I wanted to access the Oracle Web Interface for administering the database on a Cent OS system. However, I hadn't performed this oracle installation myself so I started by doing:netstat -a | moreAnd looking carefully through the list to see if I could spot it but I couldn't!Eventually I found the answer here. There is a file which contains the Oracle Enterprise Manager URL for each database

I installed Oracle 11g last week on my laptop (Windows Vista Business Edition) and had no issues except a reduction in my machine's performance.However yeseterday windows update wanted to install some updates and one of which was Service Pack 2 which I let it install. Ever since then every 5 minutes I get this error message in a popup:nmefwmi.exe stopped working and was closedAfter doing some

[Week 31]These past two weeks I've been very busy with the project and finishing off continuous assessment projects. I started by looking at my method for generating the JTree. While taking Martin's comments on board I came up with a new method for constructing the tree correctly. This was great as I could then produce correct XPath expressions.I moved onto to integrating Martin's code for

[Week 29]I managed to parse some XML schema files with XSOM, produce a tree and XPath expressions this week so decided it was good time to meet with MOC again.He informed me that the tree I was producing was not fully correct for the XML schema I was using. Therefore I need to look at my parsing method again and adapt it correctly. If the tree is incorrect then it will produce incorrect XPath

[Week 27]I got a recommendation from a classmate to use XML Schema Object Model (XSOM) for the XML Schema parsing. I've looked into this and I'm glad to say after a few hours of studying the schema and search mailing list archives I'm managing to extract information from files. I've am now moving on to try and build the tree to visually represent the XML schema. I had a meeting with MOC on

[Week 26]I've been spending the last few weeks trying to get used to the Apache XML Schema API so that I can begin to extract information from XML Schema files. This is proving quite a bit more complex than I imagined and has brought me way behind schedule.I've been emailing the developers mailing list in search of support and have received some replies however I am still having problems

[Week 23]This is the main screen after the application is launch. For now I've hard coded some dumb data into the JTree for testing. To the left of the JTree is the AWT List which is contain the names of schemas loaded into the applicationHere we can see one XSD file in the AWT list on the left. Also I've added an event listener to the JTree and made use of the getSelectionPath() method which

[Week 21]Commons XML Schema model is a general purpose schema model that can be used when a Java object tree representation of an Xml schema is required. -http://bit.ly/SUxXCI found this API for processing XML schemas. It sounds like it will be perfect for my needs. Quite busy with continuous assessment projects at the moment. I will continue experimenting with this API as time allows and post

[Week 18]Last year I used Eclipse for my 3rd year project along with a plugin for designing the GUI. I started experimenting with Netbeans in September. I have found it to provide all of the functionality that Eclipse does albeit a few things are in different places, e.g. generating getters and setters for classes. However it does more out the box. The most basic version of Netbeans available for

[Week 16]Been playing around with Adobe AIR and Flex the past week. I'm trying to find effective GUI libraries for the project. Flex is very nice and quite powerful. As with all new things there is a little learning curve though! I'm still getting used to the components. I have learned that it may not be possible to integrate an Adobe AIR application with Java unless I used web services, ie. JSPs

[Week 8]After some tweaks to my inital draft suggested by Dr. MR and MOC my functional specification is finally complete and I submitted it today. It may be downloaded here.

[Week 1]Finally a decision was made. I deviated away from the ideas mentioned in my previous post to dive into the XML world.The project's title is XPath to SQL Converter and its aim is to provide the following features:Ability to read XML Schema (.xsd) filesBuild a tree based on schema file selectedAllow user to select nodes from the tree to build an XPath expressionAllow user to add a predicate
