I'm a newbie to tomcat and zk trying to install zk on a 64-bit machine with Ubuntu linux, OpenJDK1.6, tomcat 5.5, ant 1.7.
After copying all the .jar files into tomcat shared/lib directory, with the binary installation, i'm getting the following errors:
javax.servlet.ServletException: Servlet.init() for servlet zkLoader threw exception
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117)
org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151)

A similar access denied error comes with ZeroKode, which might be due to some tomcat setup issue.
When I try to do a source build ( ./build in zk-src-3.0.6 ) , I get the following errors:
compile:
Compiling 152 source files to /home/.../downloads/zk/tmp/zk-src-3.0.6/zcommon/debug

I get the same errors even in versions 2.4.3 and 3.0.5, which indicates that there is something wrong with the build setup!
Please suggest some solution either to the binary or src installation problems.
Thanks and regards

addng the following to catalina.policy did not help
grant codeBase "file:${catalina.home}/webapps/zkdemo/-" {
permission java.security.AllPermission;
};
By disabling security completely did give me access. For testing this is fine. However, in real web server situations I don't think turning security off is not a solution.
Any suggestions ???

With ZeroKode I'm getting the following exception:
javax.servlet.ServletException: Only one layout servlet is allowed in one context: org.apache.catalina.core.ApplicationContextFacade@300b6421

This is a new installation and not an upgrade. The HowTo indicates that during an upgrade there could be a possibility ! I've installed ZeroKode-0.8.1
Any suggestions about where I might have gone wrong?

I have had the same problem. Using tomcat5.5 on Ubuntu. Tomcat is up and running correctly, but I get the error message listed above. Its a fresh install so the upgrade fix did not work. There is only one copy of the relevant *.jar files on the system.
Any help is appreciated.
about 'javax.servlet.ServletException: Only one layout servlet is allowed in one context: ' problem,
please double check there is no other older version of zk jar files in your application or share/common folder in tomcat.
a better way to do upgrade is delete old, copy new, don't just copy and replace.
About the permission problem,
did you ever try this ?
grant codeBase "file:${catalina.home}/webapps/zkdemo/WEB-INF/lib/-" {
permission java.security.AllPermission;
};
if this still doesn't work, please make sure you modify the correct correct policy file of you tomcat.
