  • Copy the “javonet-default-configuration.xml” config file into “JLNS_HOME\server\server-resources”

These are all of the steps required to install JJE binary files on JLNS platform. Before running first application the JJE must be configured.

Extension – Global Configuration

All of the configuration should be performed within the “javonet-default-configuration.xml” file stored in the “JLNS_HOME\server\server-resources” folder.

The file is the Java spring configuration file which contains the Javonet configuration and definition of custom Javonet JLupin Sequencer and input output converters for .NET objects.

To setup the extension you need to modify the first registration of javonetJLupinConfigurationData bean. Below you can see the default content of that registration.

<bean id="javonetJLupinConfigurationData">
<property name="licenseKey" value="your-javonet-license-key" />
<property name="email" value="" />
<property name="dotNetFramework" value="v40" />
<property name="autoScanDlls" value="true" />

Here you should modify the properties setters to proper values.

Table below represents the details about each property and valid inputs:

Property Description Value

  • v45
  • v40
  • v35

dllsToLoad (optional) This property should be used only if autoScanDlls has been set to false.

This property expects the list of strings with the DLL names that should be loaded by Javonet.


After completing this configuration you are ready to build and deploy your first .NET application on JLNS platform.
