I have a JRuby script that works fine through the JRuby command line. However when I execute the same script in an embedded environment, Tomcat/bsf/jruby, I get undefined method errors. Any pointers as to why the script does nto work in the embedded environment?
Thanks,
Ed
code below works with JRuby CLI but not in embedded JRuby!!!
MyHash = {"1" => "One", "2" => "Two", "3" => "Three", "4" => "Four"}
def getMaxList(hash,num)
(num < hash.size) ? hash.values[0..num-1] : hash.values
end
puts getMaxList(MyHash,2).inspect
need to use the alternate form below instead
def getMaxList(hash,num)
result = []
for i in 0..num-1
result << hash[i.to_s]
end
result
end
The error I get with the first form of the code is
<script>:6:in `getMaxList': undefined method `[]' for #<#<Class:01x12e5c94>:0xbffc3a> (NoMethodError)
from <script>:4:in `each'
from <script>:4:in `getMaxList'
from :1
