Subject Re: HTTP Session Clustering
Date Tue, 02 Apr 2019 10:23:36 GMT
Another quick update:

Adding this to my pom.xml:

<DynamicImport-Package>*</DynamicImport-Package>

solved the issue. So, I am missing an import, just not sure which one.

Here are my imports:

							org.apache.logging.log4j;version='[2.8.0,3.0.0)';provider=paxlogging,
							org.apache.logging.log4j.message;version='[2.8.0,3.0.0)';provider=paxlogging,
							org.apache.logging.log4j.spi;version='[2.8.0,3.0.0)';provider=paxlogging,
							org.apache.logging.log4j.util;version='[2.8.0,3.0.0)';provider=paxlogging,

							org.slf4j;version='[1.7.0,1.8.0)';provider=paxlogging,
							
							javax.servlet;version='[2.5,3.2)',
							javax.servlet.http;version='[2.5,3.2)',
							javax.servlet.jsp,
							javax.servlet.jsp.tagext,

							com.hazelcast.web


Thank you,
Oleg
