Testing the JNDI Installation

Use the following steps to test the JNDI installation:

1. Create a JNDI adapter LDAP entry to access a specific directory.

2. If your adapter is running out of process, start the adapter to listen for requests.

3. Resolve any error messages that appear when attempting to start the adapter.

The following table details the most common error messages that might appear when the adapter does not appear to start up correctly:

Error Message	Explanation and Action
Windows: The name specified is not recognized as an internal or external command, operable program or batch file. UNIX: java: not found	The Java executable cannot be found. Option 1—Add the full path to your Java executable to your PATH environment variable. Option 2—Add the full path to your Java executable to the startup script.
Unable to initialize threads: cannot find class java/lang/Thread	The Java executable is not able to find classes.zip or rt.jar file in its classpath. Ensure the classpath is set and that the path and file name specified are correct.
Cannot find class com.infoengine.Jndi	The Java executable cannot find the ieWeb.jar file in its classpath. Ensure the classpath is set and that the path and file name specified are correct.
java.naming.factory.initial was not set	The Java executable is not able to find a value for the java.naming.factory.initial property. Ensure this property is set either in the startup script as a command-line option or in the adapter LDAP entry.
java.naming.provider.url was not set	The Java executable is not able to find a value for the java.naming.provider.url property. Ensure that this property is set either in the startup script as a command-line option or in the adapter LDAP entry.

4. Execute a JSP page that contains a JNDI webject.

5. Resolve any error messages that appear when attempting to any webjects.

Sometimes the adapter appears to have started correctly, but certain webjects appear to fail.

The following table details the most common error messages that are displayed when the adapter appears to be running properly but webjects appear to fail:

Error Message	Explanation and Action
java.lang.NoClassDefFoundError: com/sun/JNDI/toolkit/ ComponentDirContext	Although the adapter appears to start properly, requests sent to the adapter fail and this message is displayed in the adapter startup window. This error indicates the Java executable cannot find the providerutil.jar file in its classpath. Ensure the classpath is set and the path and file name specified are correct.
DirContext error! [Root exception isjava.lang. ClassNotFoundException: com.sun.JNDI.ldap. LdapCtxFactory]javax.naming. NoInitialContextException:	Although the adapter appears to start properly, requests sent to the adapter fail. No error messages are displayed in the adapter startup window, but this error appears as the STATUS of an action webject request. This error indicates that it cannot instantiate the com.sun.JNDI.ldap.LdapCtxFactory class, meaning that the Java executable cannot find the ldap.jar file in its classpath. Ensure the classpath is set and the path and file name specified are correct.
java.lang.NoClassDefFoundError: javax/naming/directory/ InitialDirContext	Although the adapter appears to start properly, requests sent to the adapter fail and this message is displayed in the adapter startup window. This error indicates the Java executable cannot find the JNDI JAR file in its classpath. Ensure the classpath is set and the path and filename specified are correct.
