Connect Net Tcp Tridion Sites coreservice client using java


Connect Tridion Net Tcp using java

Reference: jni4net
Problem: Access nettcp connector using java which is a .Net Component
Solution: We can create .Net Wrapper which will use Tridion Core Service assembly, and we can generate java proxy using jni4net, and we'll consume those java proxies as reference for java application.

First we will create Dot.net Class library project which will deal with CoreService Assembly
Let’s give name as NetTcpConnector

Add reference TridionCoreService assembly from Tridion Sites Installation


Now you’ll see reference on projects references

Add System.ServiceModel and System.Runtime.Serialization assembly to references as shown in image above.

Then we’ll create connector class which will perform Tridion sites operation on project

We do clean and build we’ll get output dll file

Next step is Generate Java proxy using Jni4net, here are following steps to achieve it.

We’ll first download jni4net proxy

Place zip file at somewhere in your machine and extract it.
You’ll see folder structure like
Now Open Visual Studio native command prompt tool

Navigate to Jni4Net bin directory to access proxygen.exe file

And run the command
.\proxygen.exe ../../NetTcpConnector/bin/Debug/NetTcpConnector.dll -wd ../../jni4net-wd -dp ../../NetTcpConnector/bin/Debug/Tridion.ContentManager.CoreService.Client.dll

Where –wd is working directory which keeps generated build file after executed proxygen.exe
-dp represent dependency dll which is used by NetTcpConnector.dll


After executing go to working directory

Go to working directory run build.cmd file

Which generated proxy jar and dll file which will be used by java application

First we copy following files from jni4net lib folder to place it new folder called Java-jni4net-proxies-references

Also copy generated proxies using jni4net from jni4net working directory to same folder “Java-jni4net-proxies-references“ which we are going to use on java application.


Then we’ll place original .dll and core service client dll to same folder
Now we’ll write java program which calls dotnet method and provide output on java console

Add jni4net.j-0.8.8.0.jar and NetTcpConnector.j4n.jar to class path of java application


Now we’ll call GetTridionVersion method which was implementd on don.net side.

Now we run main.java
We’ll see following console which shows output of GetTridion Version method
