PHP4 and JAVA...

Anon

Hi,

In a Web-Project that I would like to do with PHP we will have the problem to interface to existing JAVA programs. Well our JAVA programmer suggested to use JSP instead of PHP. But I already made some projects with PHP and I like the language very much and I think it would be better to use PHP over JSP but I must have a way to access JAVA.

Is there a JAVA-PHP bridge available? If yes, is it stable and how good is the performance.

any advice is appreciated, thanks

What aspects of Java are you looking to work with, servlets, applets, or just plain old nifty javascript?

You can call some java via html in php, such as

// some code
?>
<SCRIPT> ...

I wonder how the using the include and require functions would work if you included some java files.. only one way to find out!

If the business logic is written in java it would be wise to use JSP. It\'s easy to learn.

This leads to an intresting situation. PHP claims to support some java interaction, and Sam Ruby is listed in the credits as haveing done java/applet support, however I dont see anything in the manual that explains the support, anyone have a pointer?

Came across this yesterday. I haven't had a chance to look through it all, but it may provide a starting for you.

Hmmm maybe I have to reconsider this I had a look at JSP and you're right it's not that hard. But somehow I find it very promising to use the best of both worlds.

Aaaahhh! That's exactly what I was looking for! At least it seems that it theoretically would work. The only Question is how fast is it g

Thanks

Dario,

There is some overhead of starting the JVM the first time. However, once it's started it is as fast as doing JNI/reflection in Java (which obviously isn't as fast as doing straight Java but don't forget that you have to compile JSPs into servlets the first time through them whereas you don't need to do that for PHP).

Note that if you have a servlet capable server, then you can eliminate the JVM overhead by using the PHP servlet extension instead of the Java extension. The servlet extension reuses the web server's JVM (and takes advantage of the pooling and caching mechanisms thereof) as well as providing all the benefits of the PHP/Java extension.
