but in my Console the following error appears:

SCHWERWIEGEND: Unable to load ~./zul/css/norm.css.dsp java.lang.NoClassDefFoundError: javassist/util/proxy/ProxyFactory at org.zkoss.zel.impl.lang.ELSupport.coerceToType(ELSupport.java:559) at org.zkoss.zel.impl.ExpressionFactoryImpl.coerceToType(ExpressionFactoryImpl.java:46) at org.zkoss.zel.ELContext.convertToType(ELContext.java:306) at org.zkoss.zel.impl.ValueExpressionImpl.getValue(ValueExpressionImpl.java:186) at org.zkoss.xel.zel.ELXelExpression.evaluate(ELXelExpression.java:41) at org.zkoss.web.servlet.dsp.impl.ActionNode$Attr.apply(ActionNode.java:132) at org.zkoss.web.servlet.dsp.impl.ActionNode$Attr.access$000(ActionNode.java:116)

What is the Problem? Thanks for the help.

It looks like you don't put this jar into your runtime classpath - https://github.com/zkoss/zk/blob/master/dist/lib/ext/javassist.jar

Hi Jumperchen,

thanks, that was the Problem. But why do i need an additional jar-File when i freshly install the actually zk-bin-8.0.0.zip? Why is the jar-File not included?

It looks like a bug when packaging
