Hi there,<br />
<br />
i have a basic question, because i'm a java beginner:<br />
Im working on a web project and my servlet needs to access some data from some &quot;information-provider&quot;.<br />
I want to write my servlet independend to the information-provider so i'm building a &quot;info-bridge&quot; bean which implements an interface.<br />
<br />
I want to use an XML file, where i can configure what &quot;info-bridge&quot; java bean should be used (a bit like the spring-bean config stuff).<br />
<br />
So i have the following XML:<br />
&lt;config&gt;<br />
&nbsp; &lt;information-interface class=&quot;myJavaPackage.myPro<wbr />ject.bridg<wbr />es.provide<wbr />r1Bridge&quot; /&gt;<br />
&lt;config&gt;<br />
<br />
What is the best way to load the class from my servlet? Is it Java Reflection or is there any other technique (because i read that java reflection is not very fast) or is there maybe any built-in feature of apache tomcat? What is common??<br />
<br />
<br />
thx for your help and best regards<br />

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

Java application servers that support the Java EE platform and features include JOnAS from Object Web, WildFly (formerly JBoss AS) from JBoss, Geronimo from Apache, TomEE from Apache, Resin Java Application Server from Caucho Technology, Blazix from Desiderata Software, Enhydra Server from Enhydra.org, and GlassFish from Oracle. Commercial Java app servers include WebLogic by Oracle, WebSphere from IBM and the open source JBoss Enterprise Application Platform (JBoss EAP) by Red Hat.

Java App Servers

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.
