Goal

To access CRX remotely in a client java program, JCR Remoting (DavEx) or RMI can be used. This post is on using JCR Remoting (aka WebDav remoting, DavEx). For RMI check this post

Solution

1) If maven is used, following are the dependencies

 <dependencies>
 <dependency>
 <groupId>javax.jcr</groupId>
 <artifactId>jcr</artifactId>
 <version>2.0</version>
 </dependency> 
 <dependency>
 <groupId>org.apache.jackrabbit</groupId>
 <artifactId>jackrabbit-jcr2dav</artifactId>
 <version>2.4.0</version>
 </dependency> 
 <dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-api</artifactId>
 <version>1.7.5</version>
 </dependency>
 </dependencies>

2) Without maven, to connect to CRX in a plain java standalone program, the following jars should be added to classpath. These jars can be downloaded from Adobe repo - Nexus

Assuming jars are available in users .m2 folder, the following paths should be added to classpath

3) A sample standalone program for connecting to CRX using DavEx and execute query, returning templates (type cq:Template)

package apps;

import org.apache.jackrabbit.commons.JcrUtils;

import javax.jcr.*;
import javax.jcr.query.Query;
import javax.jcr.query.QueryManager;

public class DavExWebDavRemotingTest {
 public static void main(String[] args) throws Exception{
 String REPO = "http://localhost:4502/crx/server";
 String WORKSPACE = "crx.default";

 Repository repository = JcrUtils.getRepository(REPO);

 Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()), WORKSPACE);
 QueryManager qm = session.getWorkspace().getQueryManager();

 String stmt = "select * from cq:Template";
 Query q = qm.createQuery(stmt, Query.SQL);

 NodeIterator results = q.execute().getNodes();
 Node node = null;

 while(results.hasNext()){
 node = (Node)results.next();
 System.out.println(node.getPath());
 }

 session.logout();
 }
}
