[OAI-implementers] Question regarding initial installation of OAICat

[Mingqiang Yu]

Hi,

I just started to use the OAICat package. After I copied the oaicat.war
file into my tomcat webapps area and restarted the tomcat, the initial
oaicat/identify.html page works ok. But when I clicked on Submit Query, I
got the following error:

java.lang.NullPointerException

        at ORG.oclc.oai.server.OAIHandler.init(OAIHandler.java:121)
....

According to the documentation, this default war file should work ok. Is
there something I did wrong?

Your help is really appreciated!
