Hello, I'm trying to get the latest zksandbox to work on Jetty 9 but it says that multiple servlets mapping to the same paths are not allowed.

As far as I can see the path "zkau" is not used multiple times but referenced as a parameter for zkLoader so I'm not 100% shure that this is a problem with zk. Maby it is an error in Jetty..

Thanks in advance, Martin

I tried with Jetty 9.2.2 but not see the issue.

Which version of Java and zkSandbox did you use to start Jetty? I have tried the same version on two computers and I can reproduce the problem. I've used OpenJDK 1.8 and zkSandbox 7.0.2.

Hello mw88,

Java version 1.8 is not officially supported.

Could you please reconfigure your project to use jdk 1.7?

Best Regards,

Darksu

This seems to have had been fixed in the latest Jetty (tried 9.2.4, and things started to work well again).

I fix this by changing web.xml header from

<web-app xmlns="<a href=" http:="" java.sun.com="" xml="" ns="" javaee"="">http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

to

<web-app version="2.4" xmlns="<a href=" http:="" java.sun.com="" xml="" ns="" j2ee"="">http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
