Is there a way to connect the JasperReports v6 server sessions to AWS Elasticache (Redis). I have downloaded and installed in the /usr/share/tomcat7/lib directory the following jar files: wget -c http://central.maven.org/maven2/redis/clients/jedis/2.5.2/jedis-2.5.2.jar wget -c https://github.com/rmohr/tomcat-redis-session-manager/releases/download/2.0-tomcat-7/tomcat-redis-session-manager-2.0.0.jar wget -c http://central.maven.org/maven2/org/apache/commons/commons-pool2/2.2/commons-pool2-2.2.jar and then change the /usr/share/tomcat7/conf/context.xml to have: <Context> ... <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" /> <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" host="redis.cache.hostname" port="6379" database="0" maxInactiveInterval="60" /> </Context> But when we try to login the /var/log/jasperreports/jasperreports.log file show: 2018-01-19 15:41:20,881 ERROR SystemErrorController,http-bio-80-exec-11:81 - Internal server error java.lang.NullPointerException at com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve.invoke(RedisSessionHandlerValve.java:28) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:169) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:962) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:116) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:445) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1115) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:316) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1152) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:622) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:748) and it show a server error. Is there a doc or HOWTO that you can point me to.
