[R] issues with rJava; cannot run JRI example

[Ajaya Mishra]

Hello,

I am trying to run JRI example from rJava, but I have some issues. I have read 
many posts and didn't find any solution to my problem.

I have the following code:

Rengine re = new Rengine(null, false, null);
System.out.println("Rengine created, waiting for R");

        if (!re.waitForR()) {
            System.out.println("Cannot load R");
            return;
        }
        
        System.out.println("re-routing stdout/err into R console");


But I get the message:

Creating Rengine........
Java Result: 10

When I run the program. It never reaches the statement below Rengine re = new 
Rengine(null, false, null); I think there might be some problem while creating 
Rengine.

Then I tried something like this: without any parameters in Rengine

Rengine re = new Rengine();

System.out.println("Rengine created, waiting for R");



        if (!re.waitForR()) {

            System.out.println("Cannot load R");

            return;

        }

        

        System.out.println("re-routing stdout/err into R console");

Now it shows me the following message:
Creating Rengine........
Rengine created, waiting for R
re-routing stdout/err into R console

which means that Rengine was created. But if i try to add some lines like this 
.....


double [] d = {1.0, 2.0, 3.0};
re.assign("a", d);

after the line above and try to run again it shows me following error messages:

#

I don't know how to solve this problem. Does anyone have idea how to solve 
this??
I have kept all the .dll files in System32 folder.


Any kind of help is appreciated.

Regards,
Ajaya
