Apache Tomcat/8.5.24

That's a known issue caused by the limitations of Tomcat running in a shared environment like this. Some have managed to get this working by playing with the sessionCookiePath in context.xml or doing various other things (such as prefixing their war with username_ which is also required if WARs need to find resources packed inside them) but its hit or miss.

 

We also don't have many Java programmers on here, so support for broken code is rather limited.

 

Others have had issues with session-related code too: https://www.helionet.org/index/topic/32294-solved-request-for-war-file-to-be-deployed/?hl=%2Bjava+%2Bsession&do=findComment&comment=145801 (no fix found)

I think that I have the same problem.

 

User name : arkham19

War file Name : mb.war

 

sessionCookiePath solution works?

How can I fix it in my site?

Putting my context.xml under WEB-INF folder in .war and upload it again?

 

Thanks

[wolstech]

Correct, you should edit the context.xml that goes in your war, rebuild the war, and redeploy it.

Perfect.

New context.xml added to mb.war under WEB-INF and uploaded.

 

Please reload, thanks

[arkham19]

Thanks wolstech, but I think it doesn't works.

 

This is my simple context.xml:

 

<Context sessionCookiePath="/">

    <WatchedResource>WEB-INF/web.xml</WatchedResource>

</Context>

 

and I have put it under mb.war\WEB-INF

I need to do something else?

 

My JSP code is also simple:

 

I set some vars like this:

   session.setAttribute("USERNAME", userName);

 

And I get this var like this:

   session.getAttribute("USERNAME")

 

It works in my local Tomcat.

(I'm sorry if I made a mistake, but I'm a newbie in JSP)

Try naming your .war file arkham19_mb.war. Sometimes .war's can't handle being renamed.

Yeeeaaahhh! Thanks Krydos, it works!
