I am new in JavaScript. I want to know how to call a simple method in Java file from JavaScript program. Could you please give me a simple example as well?
Thank you

1Please find your shift key & use it (once at the start of every sentence, and for every use of the word 'I' at the very least). This is a technical forum, not a social networking site.Andrew Thompson– Andrew Thompson2011-03-23 04:09:01 +00:00Commented Mar 23, 2011 at 4:09

By Java file you mean an Applet or Application or server side code (Servlet)?Enrique– Enrique2011-03-23 04:11:05 +00:00Commented Mar 23, 2011 at 4:11

I think you need to explain what do you mean by "Java file". Is it a Java file lying on your machine, an Applet or a server side method?Nishant– Nishant2011-03-23 04:22:07 +00:00Commented Mar 23, 2011 at 4:22

Javascript will not be able to access server side java code directly. It will need to make an ajax call to access a method or make a http call.
If you have applets you will be able to access the applet java code.
See example here http://download.oracle.com/javase/1.5.0/docs/guide/plugin/developer_guide/js_java.html

thank you. i thought i can call java method directly. i'll try to use applet.
When you say "java file" I presume you mean a Java applet. In that case, say you have this applet code on your page:
<applet id="myapplet" class="MyApplet.class" ... />
If you wanted to call the helloWorld() method in that applet, you simply need to do this:
<script type="text/javascript>
document.getElementById['myapplet'].helloWorld();
</script>
