How to pass a file into a java method

I am trying to pass a file into a java method so I can read the file from inside the method. How can I do this? I am confident passing int, char, arrays etc into methods as I know how to identify them in a methods signature but I have no idea how to decalre a file in a mthods signature. Any ideas please ?
Thanks

Hi,
Just go thru the URL,

I hope you will get a fair understanding of 'what is pass by reference/value'.
You can pass Object reference as an argument.
What Pablo Lucien had written is right. But the ideal situation is if you are not modifying the
file in the calling method, then you can pass the String (file name) as an argument to the called method.

How to call a java method so I can pass a file into the method

I want to pass a file into a java method method from the main method. Can anyone give me some help as to how I pass the file into the method - do I pass the file name ? are there any special points I need to put in the methods signature etc ?
FileReader file = new FileReader("Scores");
BufferedReader infile = new BufferedReader(file);
Where am I supposed to put the above text - in the main method or the one I want to pass the file into to?
Thanks

It's a matter of personal preference really. I would encapsulate all of the file-parsing logic in a separate class that implements an interface so that if in the future you want to start taking the integers from another source, e.g. a db, you wouldn't need to drastically alter your main application code. Probably something like this, (with an assumption that the numbers are delimited by a comma and a realisation that my file-handling routine sucks):
public class MyApp{
public static void main(String[] args){
IntegerGather g = new FileIntegerGatherer();
Integer[] result = g.getIntegers(args[0]);
public interface IntegerGatherer{
public Integer[] getIntegers(String location);
import java.io.*;
public class FileIntegerGatherer implements IntegerGatherer{
public Integer[] getIntegers(String location){
FileInputStream fs=null;
try{
File f = new File(location);
fs = new FileInputStream(f);
byte[] in = new byte[1024];
StringBuffer sb = new StringBuffer();
while((fs.read(in))!=-1){
sb.append(new String(in));
StringTokenizer st = new StringTokenizer(sb.toString(),",");
Integer[] result = new Integer[st.countTokens()];
int count = 0;
while(st.hasMoreTokens()){
result[count]=Integer.valueOf(st.nextToken());
count++;
catch(IOException e){
//something sensible here
finally{
if(fs!=null){
try{
fs.close();
catch(IOException f){
return result;
Once compiled you could invoke it as java MyApp c:\myInts.txt
Sorry if there are typos in there, I don't have an ide open ;->

How to pass a JavaScript variable into a java method

I would like to know how to pass a JavaScript variable into a java method with in a <% %> tag inside a JSP file like so:
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<script LANGUAGE="JavaScript">
myValue = someDynamicValue;
<% System.out.println(myValue)%>
</script>
</head>
<body>
</body>
</html>
obviously "System.out.println(myValue)" will not work because myValue is seen as a java variable and not a JavaScript variable.
I would like to know how to let the jsp file, that I wrote in the above code, see myValue as a JavaScript variable and not a java variable so that I can pass it to a java method.
NOTE: the java method does not have to be a println() method, it can be any method of my choice.
NOTE: someDynamicValue is a JavaScript value that can dynamically change

I don't believe you can. JSPs are really just elaborate templates that an engine such as Tomcat parses and generates an HTML page based on. That page is then displayed to the user. By the time you want to use some function in Javascript, the JSP has already been parsed and generated.
Basically, Javascript and JSPs can't talk to each other. One's server-side and the other is client-side.

How do you convert a jar file into a java file, ?

how do you convert a jar file into a java file ?
I am new to Java ,but have a little experience in C++ and Visual Basic.
I want to edit and maybe create my own mobile games that are written or converted into jar files.
At the moment I am using Java NetBeans , and Easy Java( the java pad).
However the only solution I tried was to open the JAR file in winrar and see that its made up of png picture files,
midi music files and class files. Unfortunately when I uncompressed the JAR file , there was NO java file to be seen and the JAVA editors Do not show the class file like a Java file. So why is there no extension Java file in the mobile JAR game ?

I want to edit and maybe create my own mobile games that are written or converted into jar files.Eh?
Are you saying you want to take existing games and modify them? If the creators allow you to modify their source, then they'll provide you with that source (the .java files). If you're allowed to add things but not modify, you don't need .java files. Just documentation, which, again, the creators should be providing.
Or are you saying you want to create your own games and distribute them in jar files? If so, there's no need to turn jars into .java.

Open a file into a java app - HOW DO YOU DO IT!!

I have written an html/php editor - I want to set it up so that when you double click on a php file in windows it will open the file into my java ide.
I know this can be done - but how!!! There does not seem to be any info on the web about it - can anyone give me some pointers.
Thanks

Yeah - but the problem is: You can only set files to
open with a .exe file - if you go to the settings and
set the .php file to "open with" you have to select a
.exe file e.g. notepad.exe
However you can't create .exe files in java!!!! So how
do you do it?You have to spend $$$'s
However many /most converters don't work without the relevant updated JVM (but they are *.exe, kind of)

How to include .js file into validater-rules.xml

iam doing project using struts.
i have .js file for client side validation.how to include .js file into struts validate-rules.xml so that i can use those validation in my project.
without writing any class.
is there any way

copy + paste from my book...............
Enabling Client-Side Validations
In addition to providing a framework for simplifying server-side form data validations, Validator provides an easy-to-use mechanism for performing client-side validations. Each validation routine defined in the validator-rules.xml file optionally specifies JavaScript code that can be run in the browser (client side) to perform the same validations that take place on the server side. When run on the client side, the validations will not allow the form to be submitted until they have all passed.
To enable client-side validation, you have to place the HTML Tag Library's javascript tag in each JSP for which you want validation performed, as shown here:
<html:javascript formName="logonForm"/>
The javascript tag requires that you use the formName attribute to specify the name of a <form> definition from the validation.xml file, as shown here, for which you want validations performed:
<form name="logonForm">
<field property="username" depends="required">
<arg0 key="prompt.username"/>
</field>
<field property="password" depends="required">
<arg0 key="prompt.password"/>
</field>
</form>
All the validations that you have specified for the <form> definition to run on the server side will be run on the client side.

How to use .properties files in Webdynpro Java code?

Hi all,
I want to use a logon.properties file when I initial a JCO connection pool in my webdynpro DC (JCO.addClientPool()),but I found when I deployed this DC to the server, it always giv e me an FileNotFoundException. So I donot know how to deploy a .properties file to the server and how to access this file in my Java code?
Thans and Best regards

Hi,
1) put .properties file to your packege under src\packages folder (src\packages\com\sdn\properties\jco.properties)
2) load property:
     final InputStream is = getClass().getClassLoader().getResourceAsStream("com/sdn/properties/jco.properties");
     final Properties properties = new Properties();
     try
          properties.load(is);
     catch(Exception e)
          wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);

How to convert jpeg files into word

How to convert jpeg files into Word

Hi Eugene,
I don't think you can convert an image to a Word document, but you could place the JPEG into a Word document using the Insert > Object command in Word.
For other questions relating to Word, you will probably have more luck getting an answer if you post on the Microsoft forums (we can help if you're using Acrobat, or another Adobe product, but you'll find the Word experts on the Microsoft forums.)
Best,

How to add PDF files into a slides? (Flash 8)

I am new to flash and I am using Macromedia Flash 8. My task is simple enough: I need create a Presentation with Screens from PDF files: I have 10-12 PDF files which I want convert into flash presentation.
I have read this tutorial:
http://w3.id.tue.nl/fileadmin/id/objects/E-Atelier/Phidgets/Software/Flash/fl8_tutorials.p df
Chapter 11: Basic Tasks: Create a Presentation with Screens.
I'm having trouble how to add PDF files into a slides: I want insert a whole pdf file as separate slide, without splitting pdf file into separate elements: pictures, text, etc. I tried import pdf file into Flash, wheen import there is shown prompt how program should process this pdf file(add in stage, library, as keyframes, etc) , not clear which option is correct for my task. What I got is pdf file splitted into multiple images, text, - which is not what I want. I want keep PDF files without changes, preserve original design and formatting, just convert this pdf into flash, so presentation will consist of PDFs organized in correct order, then add navigation buttons and some effects. How to solve this task?

Just to avoid potential confusion... PDF is an Adobe format, but Flash 8 is/was not. Flash 8 came out before Adobe bought Macromedia. Even today, I don't believe anything has been done to accomodate direct integration of PDF content in Flash.
