The display need to hold a valid URL. Try something like

 

  …display=file:///d:/Work/EHCL/ProjectHMI/EHCL1.bob

Subject: [EXTERNAL] Display Builder Web runtime exception

Hello,

    I would like to use DBWR on windows system with tomcat9.

Prebuild dbwr.war has been used in webapps of tomcat.

 

The url i am trying on the browser is

http://localhost:8080/dbwr/view.jsp?display=D:/Work/EHCL/ProjectHMI/EHCL1.bob

 

Which gives an error 

Exception

                org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:51)
