Hi,
Good evening.I have a query i.e how to call Java program from .net.So i searched in
google and
found JNbridge.I downloaded jnbridge software and tried to do some small
experiment.But unfortunately i face few problems.
I have created a windows form with 3 text boxes and one button.First two textboxes to
enter some numbers when you click the button it has sum both and put into the third
textbox
Ex:
First N0:12
Second No:13
Result :25
Submit // this button
To add i written add method in java i want to call the same.This is my requirement.
when i click button i used the following code
int n1,n2,result;
Addjava a = new AddJava();
n1 = Int32.Parse(textBox1.Text);
n2 = Int32.Parse(textBox2.Text);
result = a.add(n1,n2);
textBox3.Text = result.ToString();
Java file will be
public class AddJava
{
public int add(int a ,int b)
{
int result;
result = a+ b;
return result;
}
}
First i compiled java file.Using jnbridge i created the dll and added the references
to the project AddJava.dll.It asked one more dll to add i.e JNBShare.dll i have added
the same.
Compilation went through fine but failing in execution.
To do this program Remoting is essential ? If yes than why ?
The sample example they are using remoting so i copied all the files to the related
directories and executed.I am facing the following error when i create a object of
java class.
creating binary server
A communications error was encountered.
If this error persists, please contact [EMAIL PROTECTED]

Can anybody faced this problem before ? If yes provide me your suggestion else give
some URLs where
i can get good example about communication from .net to java and vice versa.
