EchoPointNG (EchoPoint, Next Generation) is a library of additional components for Echo2, it is a port of the EchoPoint component library for the original Echo2 framework. Itz available in cvs or you can get it from "EchopointNG".
Just unzip the archive.It contain the project files of the components.. I mean the class files. Make a jar using them using Apache Tomcat.EchoPointNG comes bundled with an ANT build file, unfortunately it does not work out of the box when using the latest version of Tomcat. To build EchoPointNG with Tomcat 5.5.9, open the included build.properties
CATALINA_HOME=/java/tomcat-4.1.24

Substitute the value with your the directory for your Tomcat installation, next, look for a line that looks like this:

javax_servlet_jar=/java/tomcat-4.1.24/common/lib/servlet.jar

Again, change the value to the location of your Tomcat installation, and change the filename from servlet.jar to servlet-api.jar. EchoPointNG needs the JSP API in its classpath as well, which the servlet-api.jar jar file does not include. Add an additional line to build.properties that looks like this:

javax_jsp_jar=/opt/tomcat/jakarta-tomcat-5.5.9/common/lib/jsp-api.jar
Substitute the location as appropriate for your Tomcat installation. Next, open build.xml, and look for a section that looks like this:

 <path id="library_class_path">
<pathelement location="projects/jar/bin"/>
<pathelement location="${javax_servlet_jar}"/>
<pathelement location="${echo_app_jar}"/>
<pathelement location="${echo_webcontainer_jar}"/>
<pathelement location="${echo_webrender_jar}"/>
<pathelement location="${junit_jar}"/>
</path>

Add a the following line anywhere between the
and tags:

<pathelement location="${javax_jsp_jar}"/>


The default ANT target will generate a jar file named something like echopointng-2.0a5.jar,
javadoc, a war file with a deployable web application demonstrating all of the EchoPointNG components. To develop applications using EchoPointNG, the echopointng-2.0a5.jar must be in the CLASSPATH (the exact name of the jar file will depend on the version of EchoPointNG
downloaded.
