Re: Error message on running Barracuda App in Enhydra5.1

Hi,

It is me again.

The error message I encountered earlier is fixed after inserting 
barracuda-core.jar and log4j-1.2.6.jar in input/run.in and bin/ant files.

Now, I have problem in deploying .war file created from the application 
in Tomcat. I did the followings:

1.    Copied ../output/lib/MyPage.war to /usr/local/tomcat/webapps 
(another machine, running tomcat).

2.    Restarted tomcat that created itself a directory named MyPage with 
all files in  /usr/local/tomcat/webapps.

When I try to access the page with http://hostname:8080/MyPage/mypage, I 
get the following message (in enhydra, I can access that page with /mypage):

*type* Exception report

*message*

*description* _The server encountered an internal error () that 
prevented it from fulfilling this request._

*exception*
