JRUBY : 1.7.8


I am getting the classloader issue for jline. When I tired to debug with
pry it load the jline class successfully , but without debug mode it
just failed to load the class.

-----------------------------

I am using my project.jar which have included
jruby-core-complete-1.7.8.jar and jruby-stdlib-complete-1.7.8.jar. I
checked manually the jline package included in the
jruby-stdlib-complete-1.7.8.jar, but the log says it looks from
jruby-core-complete-1.7.8.jar , not sure. Please help.

Now , I just extract the jline.jar from jruby-complete-1.7.8.jar and
export in the CLASSPATH externally and it works fine. But I want to use
the jline from jruby-complete-1.7.8.jar. Please help!

Hi Christian,

Thanks for your help. I tried your command it works fine in prompt. How
can I used it my code? Do I have to use always pry , can't we load the
class without pry.Please help.



java -jar jruby-complete-1.7.8.jar -e 'p require "readline/jline-2.11";p
$CLASSPATH'
true

Hi Christian,

In the code I tried

p require "readline/jline-2.11"
p $CLASSPATH

It loaded successfully i.e.

true

["file:/home/Khirod/myproject/lib/ojdbc6.jar",
"file:/home/Khirod/myproject/lib/jruby-complete-1.7.8.jar",
"file:/home/Khirod/myproject/lib/mycustom.jar",
"jar:file:/tmp/jruby5839733601718663013extract/jruby-stdlib-complete-1.7.8.jar!/META-INF/jruby.home/lib/ruby/shared/readline/jline-2.11.jar"]

I used the java_import to load ConsoleReader i.e.

java_import 'jline.console.ConsoleReader' Here it is still failed to
load the class jline.console.ConsoleReader.
