Sample client

You can make use of the OpenKM Maven Repository and the right SDK version. This is a sample pom.xml configuration:  

<?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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
 
  <groupId>com.openkm.sample</groupId>
  <artifactId>sample</artifactId>
  <version>1.0-SNAPSHOT</version>
 
  <repositories>
    <repository>
      <id>openkm.com</id>
      <name>OpenKM Maven Repository</name>
      <url>http://maven.openkm.com/maven2</url>
    </repository>
  </repositories>
 
  <dependencies>
    <dependency>
      <groupId>com.openkm</groupId>
      <artifactId>sdk4j</artifactId>
      <version>2.3</version>
    </dependency>
  </dependencies>
</project>

Your first class:

import com.openkm.sdk4j.OKMWebservices;
import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.bean.Folder;
import com.openkm.sdk4j.exception.*;
 
/**
 * Sample OpenKM SDK client
 */
public class Main {
    public static void main(String var[]) throws Exception {
        String url = "http://demo.openkm.com/OpenKM";
        String user = "user5";
        String pass = "pass5";
        OKMWebservices okm = OKMWebservicesFactory.newInstance(url, user, pass);
 
        for (Folder fld : okm.getFolderChildren("/okm:root")) {
            System.out.println("Folder -> " + fld.getPath());
        }
    }
}

Jar sample

If you use "maven-assembly-plugin" rather "maven-shade-plugin" you will get an error "missing MessageBodyWriter" while uploading a new file across the SDK.
