In Ext Gwt or GXT there are various ways to intercept drag and drop events directed at a Tree or TreeGrid. However, many of these do not necessarily lead to the expected results. There is also not much documentation of how to work with these events. 1. Implement the Interface
I just spend a while to find the right repository for the gwt-maven-plugin version 2.1.1-SNAPSHOT. To cut it short, one possible repository is: <pluginRepositories> <pluginRepository> <id>Codehaus Group Snapshots</id> <url>https://nexus.codehaus.org/content/groups/snapshots-group/
Really exiting about GWT is the promise to develop sleek user interfaces with Java; even the GWT UIs created out of the box look quite impressive when compared for instance, with a vanilla Swing interface. However, a number of frameworks help tremendously in unleashing the full capabilities JavaScript offers nowadays.
The Problem You want to exclude certain files and folders from being uploaded to the SVN repository in eclipse. However, some files in the project allow you to right-click them and select Team / Add to svn:ignore and for other files this action is 'greyed out'. The Solution
Both eclipse and the Netbeans IDE provide strong tool support for deploying applications based on their respective platforms. This includes supports for branding for instance with custom splash screens as well as creating executables for various platforms (Windows, Mac OS X, Linux). Eclipse allows to define Product configurations, which can
The Problem After generating an eclipse project using both the Maven Eclipse Plugin and the Maven Bundle Plugin (BND), eclipse warns that "build.properies does not exist". The Solution Maybe more a workaround than a solution but it is relatively simple to create the build.properties file manually
The Problem After generating the MANIFEST.MF with the Apache Felix Maven Bundle Plugin (BND) for an eclipse project, eclipse warns that "No required execution environment has been set". The Solution The solution is to add an instruction to the configuration of the maven bundle plugin and explicity
Many different solutions to persistence follow a similar structure: a hierarchical organization into files and folders. It appears sensible to access these representations using a common application interface. Initially, I implemented my own little library, which was capable of accessing files on the hard disk and keeping them in memory.
There are a number of different ways in which objects or object graphs can be serialized and deserialzed in Java. One major distinguishing feature is the intrusiveness of the employed framework. Some, like XStream, can work with any Java object without modification. Others, like JDO, beans serialization frameworks or the
In some circumstances, for instance if you want to transfere objects via GWT RPC, it makes sense to assert Objects can be serialized and deserialized without problems. Further there might be some differences between the original object and the deserialized object - for instance some hash tags might have changed
The Problem: You have a number of projects in an eclipse workspace. You have had bad expierences with eclipse Maven plugins like m2maven and eclipse IAM. You usually trigger Maven from the command line but now for convienience you just want one command with which you can compile all the
The Java world is in movement. After Oracle‘s purchase of Sun there is a great amount of uncertainty regarding the future of this programming language. How can we deal with this uncertainty? One approach is to understand that Java is not Java. Indeed, the way we write Java code
