There are surprisingly few frameworks, which allow to persist and query Java objects independent of relational database management systems. To me, at least for implementations not bound to using existing relational databases, storing information in interrelated tables seems an arbitrary step in object-oriented development. Below a few links ... Frameworks/Technologies
Abstract: The largest parts of the Hamcrest library can be compiled in GWT. Just the IsInstanceOf class needs a bit of tweaking (as well as some other classes depending on reflection). The following provides a brief overview of some of the steps required to compile Hamcrest with GWT. 1. 1.
Problem In its 2.0 version, it seems that Restlet has no built in support for HTTPS (see internal connectors). If trying to add a new server with the HTTPS protocol Server server1 = component.getServers().add(Protocol.HTTPS, "localhost", 8183); A warning will be thrown and the server
Problem Restlet works well with GWT RPC calls. However, for GWT‘s RPC deserialization mechanism, the classes of transmitted objects must reside in the servlet‘s thread classloader. In an OSGi environment, the classes, which need to be deserialized often reside within a different bundle than the servlet. This leads
Problem After adding a dependency to a GWT module, which is declared as Maven dependency, GWT Maven plugin does not compile correctly. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] GWT Module org.restlet.Restlet not found in project sources or resources. [INFO] ------------------------------------------------------------------------ Solution The solutio
After some difficulties I got a project working, which consists of a simple GWT application with a Restlet backend. The application consists of four OSGi bundles, which work inside eclipse PDE. Also, all of these modules and their dependencies are declared using Maven 2. Overview: The user interface is based
+++Google Guava+++ Google Guava is a collection of libraries provided by google under Apache licence to support a number of common problems in developing Java. It also provides a number of interfaces and implementations, which allow to develop in a more functional style. A good tutorial on these can be
Problem: Accessing resources using the CLAP protocol in Restlet becomes troublesome in an OSGi environment. In particular, if the Restlet libraries are in a different bundle than the resources, which shall be accessed using the CLAP protocol. Solution: Although it might be more than a workaround than a solution, it
Steps 1. Download the latest Maven distribution zip from http://maven.apache.org/download.html 2. Extract the Zip 3. Consult the README.txt. Here you will a description of the following steps. 4. Add Maven to your path. The procedure is similar as described here for Windows Vista: http:
Problem How to stop svn from synchronizing eclipse meta data in a project (eg .project files) Solution Add a number of project specific or global svn ignore directives. In the latter case, eclipse meta data will be ignored in all of your projects. You can add the following pattern for
Summary: Some steps and resources to set up a GWT project, which uses OSGi and Maven. However, these steps do not lead to a fully working GWT application. The main difficulty lies in the Server side, where the GWT servlets do not start up properly in the OSGi environment. I
The following describes a number of simple steps to set up and start up a web server in the eclipse PDE environment. Steps 1. Create a new OSGi run configuration 2. Add the package org.eclipse.equinox.http.jetty 1. Click on „Add Required Bundles“ A number of bundles should
