Basic concepts

Authentication

First, you must create the webservice object:

OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

Then you should log in using the method “login”. You can access the “login” method from the webservice object “ws” as shown below:

ws.login(user, password);

Caution

Once you are logged in with the webservices, the session is kept in the webservice object. Then you can use the other API methods.

At this point you can use all the Repository methods from the “repository” class as shown below:

ws.repository.getAppVersion();

package com.openkm;

import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.exception.DatabaseException;
import com.openkm.sdk4j.exception.RepositoryException;
import com.openkm.sdk4j.exception.UnknowException;
import com.openkm.sdk4j.exception.WebserviceException;
import com.openkm.sdk4j.impl.OKMWebservices;

public class Test {

    public static void main(String[] args) {
        String host = "http://localhost:8080/openkm";
        String user = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(user, password);
            System.out.println(ws.repository.getAppVersion());
        } catch (RepositoryException e) {
            e.printStackTrace();
        } catch (DatabaseException e) {
            e.printStackTrace();
        } catch (UnknowException e) {
            e.printStackTrace();
        } catch (WebserviceException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Accessing API

OpenKM API classes are under com.openkm package, as shown in this Javadoc API summary.

Note

At the main URL http://docs.openkm.com/javadoc/ you can see all available Javadoc documentation.

At the time of writing this page, the current OpenKM version was 7.1.5, which may change over time.

Tip

There is a direct correspondence between the classes and methods implemented in the com.openkm.api packages and available from the SDK for Java.
