Splunk SDK not working with JRUBY 1.7.19

[moofish32]

I am receiving Nokogiri errors attempting the basic tutorials with jruby 1.7.19 splunk sdk 1.0.4.

I am receiving the following error message when running the tests and similar error in IRB

Error: test_nokogiri_atom_without_feed(TestAtomFeed)
: NoMethodError: undefined method `name' for []:Nokogiri::XML::NodeSet

✗ java -version
java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)

However the same scenario is successful with MRI ruby 2.1.5.

Hi @moofish32, we will look into this.

Hi @moofish32, I'm able to reproduce your error. But, if I run gem install nokogiri --pre that seems to solve the problem by getting a prerelease version. This issue may be directly related to jruby and nokogiri. They have some other resources you may want to look into:

• Nokogiri and JRuby
• Pure Java Nokogiri for JRuby

If that doesn't solve your problem, please let us know

Closing as there are no updates.

Hi, I have the exact same issue and the links that were added above did not give a clue about how to fix this.
Is there any solution that was found?

My partial runtime error:

:error=>#<NoMethodError: undefined method name' for []:Nokogiri::XML::NodeSet>, :backtrace=>["C:/Users/---/Desktop/logstash-5.0.2/logstash-5.0.2/vendor/bundle/jruby/1.9/gems/splunk-sdk-ruby-``1.0.5/lib/splunk-sdk-ruby/atomfeed.rb:255:in read_entry_field'"

[shakeelmohamed]

@itzikh did you run gem install nokogiri --pre?

[itzikh]

@shakeelmohamed yes, i have.
If it's any help, i'm using the sdk as an input plugin for logstash and thats when i get the error.
If any logs are needed, ill be happy to provide.

[shakeelmohamed]

@itzikh sure, we can take a look with some additional logs.

Ok, So these are the mentioned logs - working with Splunk sdk as a logstash input:

This only happens when running service.create_search and does not happen with service.create_oneshot

@shakeelmohamed just a small update, i removed the nokogiri gem completely and re installed it using gem install nokogiri --pre just to be on the safe side. still did not work.

Do you have any idea on weather or not this is going to be fixed?

[tdhellmann]

Hi @itzikh - I suspect there is something going on with that version of nokogiri. Can you try uninstalling nokogiri and running the examples again? The SDK should run without it.

[itzikh]

Hi @tdhellmann , I uninstalled nokogiri (double checked with gem list)
but still the exact same error occurs.

[tdhellmann]

Wait, the same exact error? What's the result of running:

ruby -e "require 'nokogiri'"
