    <p>I'm trying to look at cucumber for Jruby on Rails. One of the pre-requesites is webrat which has as pre-requisite hpricot.</p> <p>I've installed the gem with hpricot using:</p> <p>gem install hpricot --source <a href="http://code.whytheluckystiff.net" rel="nofollow noreferrer">http://code.whytheluckystiff.net</a> --version 0.6.1 --platform java</p> <p>This installs the java version of hpricot. I add the hpricot_scan.jar to the CLASSPATH but when I run:</p> <pre><code>cucumber features -n </code></pre> <p>I get the following output:</p> <pre><code>HpricotScanService.java:931:in `hpricot_scan': java.lang.NoSuchMethodError: org.jruby.runtime.builtin.IRubyObject.getInstanceVariable(Ljava/lang/String;)Lorg/jruby/runtime/builtin/IRubyObject; from HpricotScanService.java:1324:in `__hpricot_scan' from null:-1:in `call' from InvocationCallback.java:67:in `execute' from FullFunctionCallbackMethod.java:69:in `call' from DynamicMethod.java:243:in `call' from CachingCallSite.java:283:in `cacheAndCall' from CachingCallSite.java:121:in `callBlock' </code></pre> <p>etc.</p> <p>If I compile the HpricotScanService.java file and add the resulting .class file to the classpath, I get:</p> <pre><code>Then I should see "Run" private method `scan' called for Hpricot:Module (NoMethodError) features/step_definitions/webrat_steps.rb:94:in `/^I should see "([^\"]*)"$/' features/manage_activity.feature:9:in `Then I should see "Run"' </code></pre> <p>If I try to install later versions of the hpricot, then I get:</p> <pre><code>ERROR: Failed to build gem native extension. C:/Program Files/Ruby/jruby-1.2.0/bin/../bin/jruby.bat extconf.rb install hpricot --platform java C:/Program Files/Ruby/jruby-1.2.0/bin/../lib/ruby/1.8/mkmf.rb:7: JRuby does not support native extensions.

(Not ImplementedError) from C:/Program Files/Ruby/jruby-1.2.0/bin/../lib/ruby/1.8/mkmf.rb:1:in `require' from extconf.rb:1 </code></pre> <p>Does anyone have any clues as to what I'm doing wrong/not doing/where I'm being stupid.?</p> <p>Using Windows XP, JRuby 1.2.0</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
