[opencms-dev] OpenCMS authentication

[Bill Edwards]

When I try to run the attached code, I get the following:

java.lang.NullPointerException
    at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:1835)
    at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:755)
    at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:780)
    at org.opencms.main.OpenCms.initCmsObject(OpenCms.java:541)
    at 
org.frontier.ecog.opencms.auth.OpenCmsAuth.<init>(OpenCmsAuth.java:40)
    at org.frontier.ecog.opencms.auth.OpenCmsAuth.main(OpenCmsAuth.java:60)

Any pointers would be welcome.  I would like to authenticate to OpenCMS 
from another (Web) application to save double authentication on our 
system.   Thanks. -- Bill Edwards
