References to EJB Components

Symbolically link the ejbServlet_Security.jar file either in the

iTPWS_INSTALL_DIR/servlet_jsp/common/lib directory or in the

WEB-INF/lib directory for every application that uses EJB.

The following alternatives in Example 6-3 show you how to use OSS Shell commands

to add the ejbServlet_Security.jar file to a web application called myEJBApp,

which uses EJB.

References to EJB Components

Environment entries allow passing parameter values (that may change at deployment

time) to a web application. The <env-entry> tag in the web application's

WEB-INF/web.xml file provides this functionality. Refer to the Java Servlets™

Specification Version 2.3 for more details. The environment entries support only the

following types:

java.lang.Boolean

java.lang.Byte

java.lang.Double

java.lang.Float

java.lang.Integer

java.lang.Long

java.lang.Short

java.lang.String

When the environment entry is an EJB component, the special <ejb-ref> tag must

be used. This allows the Java code running in the NSJSP container a way to get a

handle to an EJB using an abstract name.

The <ejb-ref> tag supports the following elements (tags under it):

Description of the EJB reference. This entry is optional but it is a good idea to

provide it as it helps in clarifying the purpose of this <ejb-ref> element.

Example 6-3. Linking ejb.jar Files to Web Applications

osh> cd /usr/tandem/webserver/servlet_jsp/common/lib

osh> ln -s /usr/tandem/nsejb/lib/fixup4NSJSP/ejbServlet_Security.jar .

osh> cd /usr/tandem/webserver/servlet_jsp/webapps/myEJBApp

osh> mkdir -p WEB-INF/lib

osh> cd WEB-INF/lib

osh> ln -s /usr/tandem/nsejb/lib/fixup4NSJSP/ejbServlet_Security.jar .
