Luca Stancapiano created GTNPORTAL-2423: ------------------------------------------- Summary: LinkageError using JCR in a GenericPortlet Key: GTNPORTAL-2423 URL: https://issues.jboss.org/browse/GTNPORTAL-2423 Project: GateIn Portal Issue Type: Bug Security Level: Public (Everyone can see) Components: JCR integration, PC integration Affects Versions: 3.2.0-GA Environment: tomcat 6 + java 6 Reporter: Luca Stancapiano Assignee: Matt Wringe I'm trying to do a JCR call in a simple portlet. It is the portlet: {code} package org.jboss.portal.portlet.samples; import java.io.IOException; import java.io.PrintWriter; import javax.portlet.ActionRequest; import javax.portlet.ActionResponse; import javax.portlet.GenericPortlet; import javax.portlet.PortletException; import javax.portlet.RenderRequest; import javax.portlet.RenderResponse; import org.exoplatform.container.ExoContainer; import org.exoplatform.portal.application.PortalRequestContext; import org.exoplatform.services.jcr.RepositoryService; import org.exoplatform.services.jcr.impl.core.NodeImpl; import org.exoplatform.services.jcr.impl.core.RepositoryImpl; import org.exoplatform.services.jcr.impl.core.SessionImpl; import org.exoplatform.webui.application.WebuiRequestContext; public class MyPortlet2 extends GenericPortlet { @Override protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException { response.setContentType("text/html"); PrintWriter writer = response.getWriter(); writer.print("<p><a href='" + response.createActionURL() + "'>" + "Language controller</a></p>"); writer.close(); } @Override public void processAction(ActionRequest request, ActionResponse response) throws PortletException, IOException { // TODO Auto-generated method stub PortalRequestContext context = (PortalRequestContext) WebuiRequestContext .getCurrentInstance(); ExoContainer pcontainer = context.getApplication() .getApplicationServiceContainer(); RepositoryService repositoryService = (RepositoryService) pcontainer.getComponentInstanceOfType(RepositoryService.class); try { RepositoryImpl repository = (RepositoryImpl)repositoryService.getRepository("repository"); SessionImpl session = (SessionImpl)repository.login(); NodeImpl root = (NodeImpl)session.getRootNode(); System.out.println(root.getName()); session.logout(); } catch (Exception e) { e.printStackTrace(); } } } {code} and the pom.xml with the dependencies: {code} <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <!-- the parent isn't required, you can drop it if you add a groupId and version --> <parent> <groupId>org.gatein.portal.examples.portlets</groupId> <artifactId>parent</artifactId> <version>3.2.0-GA</version> </parent> <artifactId>gatein-jsp-hellouser</artifactId> <packaging>war</packaging> <name>GateIn Portal Examples - JSP Hello User Portlet</name> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>org.exoplatform.portal</groupId> <artifactId>exo.portal.webui.portal</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.exoplatform.portal</groupId> <artifactId>exo.portal.webui.eXo</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.portlet</groupId> <artifactId>portlet-api</artifactId> <scope>provided</scope> </dependency> </dependencies> </project> {code} If I use the JCR implementations in the actionProcess method of the portlet: {code} RepositoryImpl repository = (RepositoryImpl)repositoryService.getRepository("repository"); SessionImpl session = (SessionImpl)repository.login(); NodeImpl root = (NodeImpl)session.getRootNode(); System.out.println(root.getName()); session.logout(); {code} That's ok.. it returns the node root name. If I use the JCR standard interfaces instead of the implementations: {code} import javax.jcr.Node; import javax.jcr.Repository; import javax.jcr.Session; ... Repository repository = repositoryService.getRepository("repository"); Session session = repository.login(); Node root = session.getRootNode(); System.out.println(root.getName()); session.logout(); {code} I have this Exception: {code} Apr 25, 2012 5:20:40 PM org.exoplatform.portal.webui.application.UIPortletLifecycle processAction SEVERE: Error processing the action:
