Compiling the servlet
After you develop your servlet, you must compile the class. You can use a javac compiler from the command prompt or any Java IDE, such as Eclipse. To compile a servlet class, the following JAR files must be in your Java classpath:

com.actuate.iportal.jar

org.eclipse.emf.common.jar

org.eclipse.emf.ecore.jar

org.eclipse.datatools.connectivity.oda.design.jar
These files are in the following location:
<context root>\WEB-INF\lib

servlet.jar
You can find this file in different places, depending on the Actuate products installed on your computer. For example, servlet.jar can be found in the following location:
<ACTUATE_HOME>\iHub\servletcontainer\webapps\acrsse\WEB_INF\lib
