# Before running JCnfDemo

Before running JCnfDemo, ensure that:

- Natural Access is properly installed, as described in the Natural Access installation booklet.

- NaturalConference is properly configured, as described in the Overview of configuring NaturalConference.

- The board is properly configured, as described in the board installation manual.

- Java 2 Runtime 1.3.0_01 higher is properly installed.

Complete the following steps to verify the Java runtime installation:

Step | Action
1 | Enter the following command to verify that your installed Java runtime engine is compatible with JCnfDemo: java -version
2 | Under Windows, verify that the PATH environment contains the directory where the JCnfDemo library file (jninmss.dll) is installed. Under UNIX, verify that the LD_LIBRARY_PATH contains the directory that contains the JCnfDemo library file (libjninmss.so). For example, if the installed directory of the JCnfDemo program is nms\cnf\javademo, add nms\cnf\javademo to your PATH or LD_LIBRARY_PATH variable: set PATH=%PATH%;\nms\cnf\javademo (under Windows) export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/nms/cnf/javademo (under UNIX with korn shell) setenv LD_LIBRARY_PATH"$LD_LIBRARY_PATH:/opt/nms/cnf/javademo" (under UNIX with C shell) Note: The directory home\nmss_demo_java contains the \images directory and the welcome.pcm file. Under Windows, home is c:\documents and c:\settings\user\.
