# Building
Before building you should install swig and java.
From the root directory of the libiec61850 project you have to build some of the dependant libraries
> cd ..
>
> make clean
>
> make INSTALL_PREFIX=/usr/local install
>
> make clean
>
> make INSTALL_PREFIX=/usr/local dynlib
Now change into the Java project subdirectory
> cd javaiec61850
>
> swig -java -I/usr/local/include iec61850.i
>
> gcc -fpic -I/usr/lib/jvm/default-java/include -I/usr/lib/jvm/default-java/include/linux -c iec61850_wrap.c
>
> ld -shared ../build/libiec61850.so iec61850_wrap.o -o libiec61850.so
>
> javac test_javaiec61850.java
>
> java test_javaiec61850
This test programme should show an out put of
```sh
MyThread for IEC61850Server has STARTED
IEC61850Server has STARTED
IEC61850Client has connected to the IEC61850Server
IEC61850Client has read testmodelSENSORS
IEC61850Client caught a error = 0
IEC61850Client read a temperature set point of = 0.0
IEC61850Client read a temperature set point of = 10.0
IEC61850Server has been Interrupted and STOPPED
```
The CMakeLists file does not exist yet, however it would be a nice to have a build of the java bindings by turning on a BUILD\_JAVA\_BINDINGS flag in CMake from cmake-gui or in command line:
```sh
$ cmake -DBUILD_JAVA_BINDINGS=ON .
```
Then compile the library and install it.
javaiec61850 library is to be imported calling
```java
import iec61850
```
# Client tutorial
The java bindings works similarly to the python and basic C library ones.
Have a look at the Client, Server and test programme.
For example to create a connection, call:
```java
if (con == null) {
con = iec61850.IedConnection_create();
}
iec61850.IedConnection_connect(con, error, "localhost", tcpPort);
conState = iec61850.IedConnection_getState(con);
if ( conState.toString() == "IED_STATE_CONNECTED" || conState.toString() == "IED_STATE_IDLE") {
System.out.println("IEC61850Client has connected to the IEC61850Server" );
}
```
