"unable to locate a login configuration" running tomcat as a service

[Andy Fish]

Hi,

My servlet (running on Win2000) uses a login config file specified in
%JAVA_HOME%/jre/lib/security/java.security:

login.config.url.1=file:/C:/Program Files/yadda yadda.../mylogin.cfg

I am using Tomcat 4.1. and Java 1.4.2. Everything works fine when I run
tomcat in a command window, but when I try to use the tomcat service, I get

java.lang.SecurityException: Unable to locate a login configuration

as soon as I try to do a JAAS authentication. I guess there must be
something different in the environment, but I've checked the environment
variables, and I'm running it as the same user (local administrator account)

Any ideas?

Andy

Found it !!!

Looks like when you install the SDK you get 2 different installations of the
JRE in different places. I'd installed the SDK under c:\j2sdk1_4_2_02 and
set JAVA_HOME to be c:\j2sdk1_4_2_0

however, in the registry enties for the service
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Apache Tomcat
4.1\Parameters) I found

JVM Library = C:\Program Files\Java\j2re1.4.2_02\bin\client\jvm.dll

so it looks like the service is not using my JAVA_HOME variable - Presumably
it's inferring JAVA_HOME from the location of the JVM DLL. Copying the
java.security file to C:\Program Files\Java\j2re1.4.2_02\lib\security causes
it to be picked up OK
