Dear All, I've created a new installation of GeoServer 2.17.0 on Tomcat 9 and and OpenJDK 14.0.1. The only extension I've installed so far is the geoserver-2.17.0-printing-plugin, however the following url mentioned in the documentation <https://docs.geoserver.org/latest/en/user/extensions/printing/index.html> fails:
http://localhost:8080/geoserver/pdf/info.json The exception is as follows: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: 'void org.json.JSONWriter.<init>(java.io.Writer)' *Exception* org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: 'void org.json.JSONWriter.<init>(java.io.Writer)' org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1055) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:943) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1006) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:898) javax.servlet.http.HttpServlet.service(HttpServlet.java:634) org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:883) javax.servlet.http.HttpServlet.service(HttpServlet.java:741) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) org.geoserver.filters.ThreadLocalsCleanupFilter.doFilter(ThreadLocalsCleanupFilter.java:26) org.geoserver.filters.SpringDelegatingFilter$Chain.doFilter(SpringDelegatingFilter.java:69) org.geoserver.wms.animate.AnimatorFilter.doFilter(AnimatorFilter.java:70) org.geoserver.filters.SpringDelegatingFilter$Chain.doFilter(SpringDelegatingFilter.java:66) ... *Root Cause* java.lang.NoSuchMethodError: 'void org.json.JSONWriter.<init>(java.io.Writer)' org.mapfish.print.servlet.MapPrinterServlet.getInfo(MapPrinterServlet.java:290) org.mapfish.print.servlet.MapPrinterServlet.doGet(MapPrinterServlet.java:99) javax.servlet.http.HttpServlet.service(HttpServlet.java:634) javax.servlet.http.HttpServlet.service(HttpServlet.java:741) org.springframework.web.servlet.mvc.ServletWrappingController.handleRequestInternal(ServletWrappingController.java:166) org.springframework.web.servlet.mvc.AbstractController.handleRequest(AbstractController.java:177) org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:52) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1040) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:943) ... Any idea how to work around this? Thanks, Tamas Szekeres
