I created an XWiki component which is available as a jar file. I have a ScriptService class for the component too: ---- @Role public interface SearchClient { String search(); } ---- @Component @Singleton public class InternalSearchClient implements SearchClient { public String search() { return "test search results"; } } ---- @Component @Named("internalSearch") @Singleton public class InternalSearchScriptService implements ScriptService { @Inject private InternalSearchClient searchClient; public String search() { return this.searchClient.search(); } } ---- I've added all the above files into their own jar with a components.txt file: com.mycompany.wiki.search.InternalSearchClient com.mycompany.wiki.search.InternalSearchScriptService and in my Wiki's pom.xml, I have the following: <dependency> <groupId>org.xwiki.commons</groupId> <artifactId>xwiki-commons-script</artifactId> <version>${commons.version}</version> </dependency> Now from my Wiki page, when I do the following: {{groovy}} println(services.internalSearch.search()) {{/groovy}} I get an error message saying "java.lang.NullPointerException: Cannot invoke method search() on null object" What am I doing wrong here? (I followed the directions in http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents — have these directions changed, and/or is there anything else I need to do? )
