convention the VXML Server enforces the *.jar filename extension and will not load classes
with *.zip filenames. Therefore you must use *.jar filenames for classes that are developed on
Call Studio and will run on VXML Server.

When an application is deployed through Call Studio, a folder is created that encapsulates all
the information for that application, including all Java code the developer placed in the Call
Studio project as per the instructions given in the previous section. If the application is to change
in any way, from changes to the call flow, to the addition or subtraction of required Java files,
those changes must be done through Call Studio and then redeployed to VXML Server.

One deployment requirement that must be performed by the developer is to ensure that the Java
components and utility libraries stored in the 

 folder are also placed in the VXML

Server 

 folder. When an application is deployed from Call Studio, only that application’s

files are created, any common code is not included. As a result, it is the developer’s responsibility
that the contents of the 

 folder in Call Studio also appear in the VXML Server common

folder.

• When VXML Server initializes, it first loads the classes in 

 and then loads each

application’s classes. Due to the way Java classloaders work, if a Java class appears in both
the 

 folder and an application’s 

 folder, the one in 

 will take precedence

and the one in the application’s 

 folder will not be loaded.

• Due to the order in which these classes are loaded, the developer cannot place a class in

 that refers to a class that only appears in an application’s 

 folder since the

classes in 

 are loaded first. Keep in mind that some application servers have advanced

options to change this precedence to parent-last, meaning that the application-level classloaders
take precedence. By default, all application servers should be configured to be parent-first.

The 

 folder of a Call Studio project and a VXML Server application folder contain two

subdirectories named 

 and 

. Each folder encapsulates Java classes used for

different purposes, their distinctions applying primarily to how the application works within
VXML Server.

The 

 folder should contain all Java code for components that are used by the

application.

Note: In Call Studio, any custom configurable elements that are utilized only by the application
would be placed in this folder and will appear in Call Studio’s element pane under the folder
named Local Elements. The call flow editor for that application must be closed and reopened
in order for newly copied local elements to appear in the element pane.

The second subdirectory of the 

 folder is the 

 folder. This is used for Java libraries

that provide the application with utilities unaffiliated with Unified CVP (such as math libraries,
XML parsing libraries, etc.).
