Hi
I created an web application which has an integration with MS Excel. I used
jacozoom for this integration. I deploy this application on Tomcat 6.0.26.
When I run Tomcat as service my application is throwing following error.
Exception Text: com.inzoom.comjni.ComJniException: code=0x800a03ec Type=
com.inzoom.comjni.ComJniException.eComError

But when I start the Tomcat from command line it works fine without any error.
What can be the cause of this problem? The error is thrown only in case of
Windows 2008 Server. If I install the Tomcat on Windows XP it works fine( as a
service). My application has a dependency on some jacozoom dlls which are
package inside the war file. I tried keeping them outside of tomcat and giving
the full path of this folder to my application then also this fails. The
Tomcat gets started properly. It fails when accessing the URL.
I am really stuck here.
I think you should really ask the "jacozoom" people for help on this
one, because I doubt anyone here has any idea what it is trying to do.
But based on your description, I will hazard a guess :
- when you run Tomcat from a command window, it runs under your Windows
user account, with the access permissions of your user account.
- when you run Tomcat as a service, it runs under whatever user-id the
service is set up to run as (by default probably LocalSystem).
That Windows account does not have the same environment and permissions,
as your user account.
There is probably the difference.
