Body
Using Groovy 2.1.7 with JDK 1.7.0_40. I'm trying to write a very simple prototype groovy script. It's going to call RESTClient and process the results from a service. It looks something like this: <pre><code>#! env groovy @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.2' ) @Grab(group='org.apache.httpcomponents', module='httpclient', version='4.1' ) import groovyx.net.http.RESTClient; println("About to create RESTClient."); service = new RESTClient("http://myhost/") def diagnostics = service.get(path: "mypath"); println("diagnostics[" + diagnostics + "]"); </code></pre> When I run this, I get this: <pre><code>About to create RESTClient. Caught: java.lang.NoClassDefFoundError: org/apache/http/client/methods/HttpUriRequest java.lang.NoClassDefFoundError: org/apache/http/client/methods/HttpUriRequest at monitorStatus.run(monitorStatus.groovy:9) Caused by: java.lang.ClassNotFoundException: org.apache.http.client.methods.HttpUriRequest ... 1 more </code></pre> I saw one mention of needing to put the "@Grab" annotation on a method. I've tried several variations of this with thosee annotations on a method, but it made no difference. What am I doing wrong here? EDIT: I added "-Dgroovy.grape.report.downloads=true" to my JAVA_OPTS and made some trivial changes to the script. Here is my current script, with just the url and path modified: <pre><code>#! /usr/bin/env groovy @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.2' ) @Grab(group='org.apache.httpcomponents', module='httpclient', version='4.2.5' ) import groovyx.net.http.RESTClient; import org.apache.http.client.HttpResponseException; import org.apache.http.client.methods.HttpUriRequest; println("About to create RESTClient."); service = new RESTClient("http:///") def diagnostics = service.get(path: "mypath"); println("diagnostics[" + diagnostics + "]"); </code></pre> This is what I get when I run it: <pre><code>Resolving dependency: org.apache.httpcomponents#httpclient;4.2.5 {default=[default]} Resolving dependency: org.codehaus.groovy.modules.http-builder#http-builder;0.5.2 {default=[default]} Preparing to download artifact org.apache.httpcomponents#httpclient;4.2.5!httpclient.jar Preparing to download artifact org.codehaus.groovy.modules.http-builder#http-builder;0.5.2!http-builder.jar Preparing to download artifact org.apache.httpcomponents#httpcore;4.2.4!httpcore.jar Preparing to download artifact commons-logging#commons-logging;1.1.1!commons-logging.jar Preparing to download artifact commons-codec#commons-codec;1.6!commons-codec.jar Preparing to download artifact net.sf.json-lib#json-lib;2.3!json-lib.jar Preparing to download artifact org.codehaus.groovy#groovy;1.7.11!groovy.jar Preparing to download artifact net.sourceforge.nekohtml#nekohtml;1.9.9!nekohtml.jar Preparing to download artifact xml-resolver#xml-resolver;1.2!xml-resolver.jar Preparing to download artifact commons-beanutils#commons-beanutils;1.8.0!commons-beanutils.jar Preparing to download artifact commons-collections#commons-collections;3.2.1!commons-collections.jar Preparing to download artifact commons-lang#commons-lang;2.4!commons-lang.jar Preparing to download artifact net.sf.ezmorph#ezmorph;1.0.6!ezmorph.jar Preparing to download artifact antlr#antlr;2.7.7!antlr.jar Preparing to download artifact asm#asm;3.2!asm.jar Preparing to download artifact asm#asm-commons;3.2!asm-commons.jar Preparing to download artifact asm#asm-util;3.2!asm-util.jar Preparing to download artifact asm#asm-analysis;3.2!asm-analysis.jar Preparing to download artifact asm#asm-tree;3.2!asm-tree.jar Preparing to download artifact xerces#xercesImpl;2.8.1!xercesImpl.jar Preparing to download artifact xml-apis#xml-apis;1.3.03!xml-apis.jar About to create RESTClient.

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.
