Books for Java with C++

[Hitesh Kumar Pithadiya]

Hi,

I am planning to use Java along with C++ for the Server Side programming.

Can anybody suggest me some really good books for this?

Kindly suggest?

Regards,
Hitesh

What do need besides separate books on Java and C++. Do you want to build a mixed system with integrated Java and C++ parts?

[piyush aegis]

You can trying to search (like : server side programming java with c++) in Google books and refer some pages of available books,
after you got some good book than go through it.

If by C++ on server-side you mean CGI programs, then its highly outdated. If its going to be some native code, then its no where related to Java.
What is it you want to do with C++ that cannot be done through Java?

I extremely sorry that i couldn't able to reply.

Yes i'm looking for some Java with C++ Integration.

Whereas, i could integrate c++ with Java.

[Ivan Jozsef Balazs]

Do you have a concrete idea about how to integrate Java and C++?

Yes, some how i tried the Concept of JNI, where i used C++ methods in Java.

I made that program by reading an article. But , i don't want to follow any article i just want to learn JNI step by step.

Can you suggest me any book name having same concept?

[Ivan Jozsef Balazs]

So you need a book on JNI better than the article you mentioned?

[Hitesh Kumar Pithadiya]

Yes. Please suggest or is there is any other way to integrate this technologies, kindly recommend.

Besides having decided this:

you do not seem to have any more precise ideas.

I'm curious as to WHY you are starting off with "I am planning to use Java along with C++ for the Server Side programming." Isn't that putting the cart before the horse? Usually you'd start with deciding what you wanted to do before you decide on the tools.

For example, I would say "I'm going to use a blow torch and a socket set for building stuff", and then trying to figure out how to use those to cut the boards for your birdhouse.

for the Server Side programming

"The Server Side programming" is also a rather vague notion. There are many kinds of servers: HTTP, HTTPS, RMI, FTP, FTPS, telnet, ssh, scp, CIFS, echo, daytime etc. and you are free to roll out your own. What do you mean?

[Hitesh Kumar Pithadiya]

I appreciate your reply and the way you suggest me for choosing what to do first.

Actually, we have several C++ Libraries and we need to call those methods in a Swing based Software. That's why I thought that this is the only way to achieve this.

I just want to start with some basics.

[Ivan Jozsef Balazs]

So you seem to need literature on JNI. You could have asked about it in the first place.

[Hitesh Kumar Pithadiya]

Yes, it could possible.
Do you know any book,best to start with?

[Campbell Ritchie]

I looked for JNI tutorials last night and didn’t find anything I thought was any good.

[Hitesh Kumar Pithadiya]

Anyways,
I want to thank you all to suggest me and your valuable opinions.

I will buy a good book on this.

Thanks for your support.
Regards,
Hitesh

Well, this tutorial might be a place to start, but I'd also find a good book on the subject.

You should also be aware that using JNI is often a bit of a kludge, and is likely to make your app less portable; so I'd consider translating as much of your C++ stuff into Java as you can (all of it, if possible) - although, of course, that might take some time.

Thanks!
I'll follow this article.

This seems to be a relatively fresh one; last modified: July, 2012

[Campbell Ritchie]

Thank you. I shall try it. But it appears to be Windows‑based.

[Ivan Jozsef Balazs]

There are hints on Unices and .so and gcc - maybe it is applicable to Unices.

Along the above lines this works for me on
Linux 2.6.9-101.ELsmp #1 SMP i686 athlon i386 GNU/Linux

//pid.java
package pid;
public class pid {
public native long getpid();
static {
 System.loadLibrary("pid");
}

public static void main(String args[]) {
pid p = new pid();
System.out.println(p.getpid());

}
}

//pid.cpp
#include "pid_pid.h"
#include <unistd.h>

JNIEXPORT jlong JNICALL Java_pid_pid_getpid(JNIEnv *, jobject)
{
pid_t pid = getpid();
jlong ret = pid;
return ret;
}

In pid_pid.h the include was hacked:

#include "jni.h"

The wrapping script:

. ./j0
echo "$JAV/include/"
g++ -c -I"$JAV/include" -I"$JAV/include/linux" *.cpp
g++ -I"$JAV"/include" -I"$JAV"/include/linux" -o libpid.so -shared -Wl,-soname,libpid.so *.o -static -lc
$JAV/bin/java -classpath classes -Djava.library.path=. pid.pid

Where j0 sets JAV

JAV=/home/oracle/java/jdk1.6.0_04
