Nullpointerexception On Java/jsp

[rec0]

Hello,

 

I have a problem with my java/jsp application. I created it in eclipse as it was described here http://wiki.helionet.org/Java_Servlet. I have tested it on Apache 7 and selected Java 1.6

for this project. It runs ok on my local machine. I deployed it on server (rec0.heliohost.org/xmascard) and it doesn't work as it should. The problem occurs everytime I try to get object from java in jsp site. I'm trying to do it like:

<%
     Card card = (Card) session.getAttribute("card");
%> 

And when I try to use this object

<%= card.getUsername()%>

I allways get NullPointerException like this object is never loaded. As I said it works on my local tomcat 7 server so I doubt it is implementation problem. Mabye there are some version differences so I don't ask you to fix this. I would only like to know how should I pass objects (or eventually simple variables) from java code to jsp the way it works on your servers. I'd love to try it myself but long deploying times make it hard.

 

I hope you can help me

Regards,

Since you're on Tommy you're actually using Tomcat version 8.5 and java 1.8. Maybe try updating your local environment to closer to these values? Johnny has Tomcat 7 and java 1.7.

I updated project and uploaded it again and it still returns nulls. I uploaded same project on Google Cloud Platform tomcat server which is in same version as yours and it runs well.

I guess just use Google Cloud Platform tomcat server or a VPS then. I'm not sure why it would do that and you're the first person to report it.

 

The only other thing I can think of is I can try deploying your .war on my Johnny account if you want so you can see if it works there.
