Re: [WebMacro-user] #bean...scope=session no longer working?

[Keats K. <ke...@xa...>]

I spent a couple of hours setting up Tomcat 5.5.9 and cooking up some 
test cases and I can't reproduce your problem.

I put the following into a sandbox template, with no problem.  I'm using 
Win2K with Sun JRE 1.5.0_02.  I also tested with Tomcat 4.1 and 5.0 with 
JDK 1.4.2.

Your error indicates that your class wasn't instantiated.  You might try 
putting some logging into the constructor to see what's going on.  Also 
check your BeanDirective security settings.  Good luck.

Sample WMScript:

#bean $testbean = "com.xaltus.wm.Test" scope=session onNew
  #set $testbean.Num = 2
#end
#set $testbean.Num = $testbean.Num * 2
testbean.Num = $testbean.Num<br><br>
   
#bean $counts = "java.util.HashMap" scope=session onNew
  #set $counts.Hits = 0
#end
#set $counts.Hits = $counts.Hits + 1
Number of visits to this page in this session: $counts.Hits<br><br>
