Introduction

The OpenKM Document Management System (DMS) plugin facilitates the seamless integration of OpenKM and Joget. This integration currently utilises two plugin types:

  • Form Options Binder - Retrieve folder paths from OpenKM.
  • File Upload Element - Upload files to OpenKM. Bind folder paths from the select box field that uses the Form Options Binder. Able to choose whether to create folder that follows Joget form ID when uploading.
  • Datalist Formatter - Format datalist file upload column to download file from OpenKM directly.


The plugin is created with the use of RESTful Guide - OpenKM Documentation to perform RESTful API calls on OpenKM.


Plugin Info

Plugin Available in the Bundle:

  1. OpenKM DMS Plugin.

This plugin bundle is compatible with Joget DX 8.

Expected Outcome

Upon successful integration, Joget will be able to upload files into OpenKM browser based on the directory set by users.

Figure 1: Example of successful integration.

Getting Started

Prerequisites

1. Java 8 Environment

In order to successfully install OpenKM, Java 8 is an essential prerequisite that must be present on the system environment, which can be downloaded from the Oracle Official Website. This version of Java provides the necessary runtime environment for OpenKM to operate effectively and efficiently. Without Java 8, the installation process may encounter errors or fail altogether, rendering OpenKM unusable.

2. OpenKM Community Version

OpenKM Community Version can obtain it by downloading directly from the Official OpenKM Website. This official source ensures users access the most up-to-date and authentic version of the software, safeguarding against potential security risks and ensuring compatibility with existing systems.

3. OpenKM Database

OpenKM is able to integreate with MySQL, PostgreSQL, Oracle or SQL Server. In this article, we will be using MySQL as the OpenKM database.

Link to MySQL download and installation:

4. OpenKM DMS Plugin

To integrate Joget with OpenKM, we will use the OpenKM DMS Plugin from https://github.com/jogetoss/openkm-dms.


Setting up OpenKM DMS

1. OpenKM Installer Setup

To setup the OpenKM installer, open Command Prompt as Administrator and open the file directory where you stored the OpenKM installer.


In the command prompt, use java -jar OKMInstaller.jar to start installing OpenKM. After entering the command, it will display the output as image below and we can enter the configuration we prefer. 

Figure 2: OpenKM Configuration.


OpenKM installation will install Tomcat automatically in the current path directory. After successfully installing OpenKM it will display a "SUCCESS: Specified value was saved." with a database query to create the database, user and password based on the information entered in Figure 2.

Figure 3: Successful Installation.


As a confirmation of a successful installation, open Services in the computer's system and search for OpenKM:

Figure 4: OpenKM Services.


 2. MySQL setup

Access the root database to execute the query in Figure 3 to create "okmdb" database.

 Figure 5: Access Root Database.


Figure 6: Creating okmdb Database.


Go to Server > Users and Privileges and select the newly created User and check all the following boxes to give the User full privilege of the database. Not doing so will create an error when trying to access OpenKM browser.

Figure 7: Set Users Privileges.


Figure 8: Select User and Check All the Roles.


Create a new connection and enter all the information set in Figure 3.

Figure 9: Create New Connection.


3. OpenKM.cfg First Time User Setup

For first time user, an error will occur when accessing OpenKM local browser because there is no existing UUID for the current user. To prevent this error from occurring, we will need to create a UUID when loading the browser. To do so we will make some configuration in the Tomcat folder.


Open Tomcat folder > OpenKM.cfg in IDE(Visual Studio code, Intellij, etc.) and make small changes in a line of code:

Before
# OpenKM Hibernate configuration values
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.hbm2ddl=none

# Logback configuration file
logback.config=logback.xml

# LibreOffice configuration
system.openoffice.program=D:/Joget/QA/OpenKM/OKM/tomcat-8.5.69/extras/LibreOffice/App/libreoffice/program/soffice.exe


After
# OpenKM Hibernate configuration values
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.hbm2ddl=create //change in this line from "none" to "create"

# Logback configuration file
logback.config=logback.xml

# LibreOffice configuration
system.openoffice.program=D:/Joget/QA/OpenKM/OKM/tomcat-8.5.69/extras/LibreOffice/App/libreoffice/program/soffice.exe


4. OpenKM Server and Shutdown Port Changes

OpenKM Server and Shutdown Port needs to be changed since Joget's default ports will populate the same ports which prevents OpenKM from running. Thus, we need to configure the ports in the server.xml file.


Go to Tomcat folder > conf > server.xml

Server Port
<Connector port="8180" address="0.0.0.0" protocol="HTTP/1.1"
               connectionTimeout="20000" redirectPort="8443"/>


Shutdown Port
<Server port="8006" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener"/>


OpenKM in Runtime

To access the OpenKM browser, make sure the service is running as in Figure 4.

Open OpenKM in browser with http://localhost:8180/OpenKM.

When you see the following page, it shows that your OpenKM has been successfully hosted. Default login credentials are "okmAdmin" with password "admin".

Figure 10: OpenKM Login Page


After logging in, you will see the homepage of OpenKM.

Figure 11: OpenKM Homepage


Configuring the OpenKM Plugin

First, drag a select box and use the OpenKM DMS Form Options Binder to load the folder paths from OpenKM. Fill in the required credentials for the plugin to work as intended (Figure 6). The Root Folder UUID can be retrieved on the OpenKM folder that we intend to configure as root folder (Figure 7).

Figure 6: Joget Form Builder (Select Box with OpenKM DMS Form Options Binder)


Figure 7: Retrieve OpenKM Root Folder UUID 


Then, the OpenKM DMS File Upload tool can be drag and drop to attach into the form as a form element. Fill in the OpenKM Configurations with necessary details. If the credentials of OpenKM is invalid, "Authentication ERROR" will be shown in the element (Figure 8).

We can now map the select box field in the Field Mappings section. Field mappings is an optional configuration.

When configuring the Field Mapping, "Field for OpenKM Folder Path Upload" must point to the file path created in Figure 6, if no fields are mapped, the default file path will be "/okm:root".

Figure 8: Joget Form Builder (OpenKM DMS File Upload Element)


In the datalist builder, we can format the file upload column by using the OpenKM DMS Datalist Formatter. Similar configurations can be key in to enable users to download the file directly from datalist. Make sure the "file path" fields are in the datalist (can be configured to be hidden if we do not wish to show, but it must be there). If field mapping is not configured, the default file path will be "/okm:root".

Figure 9: Joget Form Builder (OpenKM DMS Datalist Formatter)


If we do not wish to type the credentials multiple times, the credentials can also be easily added into environment variables, and then use a hash variable to refer to the values in environmental variables. For more information, please refer to Environment Variable - Knowledge Base for DX 7 - Joget | COMMUNITY.


Using the OpenKM Plugin

After all the configurations has been done, the user can retrieve the folder paths from OpenKM in the select box, then choose a file to upload.

Figure 10: OpenKM DMS UI (Form)


After uploading, we can view the latest file path that the file has been uploaded to, and also download the file retrieved from OpenKM.

Figure 11: OpenKM DMS UI (List)


At OpenKM DMS, we can view the file being uploaded. If we modify the file here, we can also get the modified newest file in Joget.

Checking the field will create a different path in OpenKM and Joget. OpenKM will store it in a Unique ID path, while Joget will store the file path as '/okm:root'. The difference in paths may result in an HTTP Status 500 Error when attempting to download the file from Joget.
