Java - php

Hi
Can I ask what's wrong with the following code?
I got 2 area in a html page, I want to press a button, then it will pass some information to area 2 which is the php script to manipulate.
public void actionPerformed(ActionEvent e) {
     AppletContext ac = getAppletContext();
     try{
     URL theURL = new URL("area2.php?state=TAS");
     ac.showDocument(theURL, "area2");
     }catch(MalformedURLException me){}
}

Nice catch block there. Do nothing if an error
occurs - that's great thinking.
In general that's true of course... well, it's
entirely untrue but you know what I mean ;o) ...but
surely in the situation where you're passing a
literal which you know absolutely to be a valid
parameter, there's no real need to implement any
useful handling.Maybe someone might try to hack the bytecode...

I think it is safe to assume your network settings are wrong and it actually has nothing to do with java. Firewall problem perhaps?

Java/php bridge

Hi All,
i am working on jdeveloper10.1.3 & OracleApps Server.
suggests some possible ways to bridge Java/PHP?
I am facing problem integrating with jsp page and php page . if any one know its great help me.
What are the softwares required for bridge between java and php.
Request is so needful.
thq,
elisha.

Judging by your later response, I'd say Gene got it right first time in that it is a memory issue.
It looks like your application needs more than 512m heap size. I guess there isn't enough on the box where WebLogic is installed, otherwise you would have used the same sizes as TomCat.
Apologies if I'm stating the obvious

Issue with Java - PHP interoperability

Hi,
There are some converts written in PHP that can take raw wikipedia data and output a good HTML. I wanted to make use of these in my Java code.
So in my Java Web App, I wanted to run the PHP parser, get hold of the InputStream and push it to my ServletOutputStream.
Code Snippet:
   String command="php testparser.php Anarchism.wikimarkup";
   proc = Runtime.getRuntime().exec(command);
   InputStream in = proc.getInputStream();
   InputStreamReader isr = new InputStreamReader(in);
   BufferedReader br = new BufferedReader(isr);
   String line = null;
   while ((line = br.readLine()) != null) {
     System.out.println(line);
   }But the problem here is that the PHP Process never stops and hence the Buffer never ends. THe program is waiting in infinite loop in readLine().
Please let me know if anyone has tried this and whats a better way to handle interoperability between PHP and Java.
Thanks,
Phani

Yeah, I had a look at the document. But as per my understanding, the way the PHP engine runs is different from normal execs. I don't see how it can 'run different' and in my experience it doesn't. PHP sends output to stdout and stderr and reads from stdin. When PHP terminates it will close stdout and stderr and, if you have followed the recommendations in the reference, your readLine() will return 'null'.
Because the same code ran fine when I automated unzipping a set of files using "bunzip2" command.If you read the article it explains a possible reason for this BUT until you implement the recommendations you will not know what is wrong.

I tried using Process.waitFor() method as well, but the result is same (Infinite Loop).This almost certainly is nothing to do with Process.waitFor() and probably everything to do with buffers filling (probably stderr).
Until you post the code with the recommendations implemented that exhibits the same blocking problem it is a waste of time anyone responding further.

Authentification with Java, PHP, .htaccess

Hi there,
I am thinking about creating a Java project that requires some authentification routines.
Users (which are given a unique user ID) are employing a client software (Java) that retrieves specific data from a webserver (available ressources HTML, SSI, PHP, .htaccess).
A user should be able to use any client to get his data from the webserver, so unique client IDs are a non-option. Probably two users might even use two instances of the same client on the same machine (means, same IP).
I want this to be reasonably secure, so no plaintext protocol. I thought about something like a challenge - response architecture, BUT...
...how can I do this with only PHP (server) and Java (client) as options?
I don�t need a polished, smooth, perfect solution - a rough idea will do. Are there any secret / public key architectures with ready-to-use PHP modules that are also implemented in Java? Or has anybody a completely different idea I haven�t thought about yet?

Have a look on RFC 2617 from IETF (www.ietf.org). This RFC specifies two mechanisms for authenticated access to HTTP resources. .htaccess is based on these mechanisms. Unfurtonately, they are not secure enough. The first protocol, BASIC, sends clear text username/password. The second, DIGEST, sends digests of the username/password using a challenge-response scheme. The disadvantage of DIGEST is that the username/password needs to be stored in clear on the server-side.
What you could do, which is something I am currently working on myself, is to implement your own protocol, based on this RFC. This is possible because you are in control of both the clients and the server. It wouldn't be possible if standard browsers where used as clients.
Good luck!

Java - PHP communication

Hi,
I'm quite new to EJB3 and going to build web application using (probably) EJB3 and Struts 2. My problem is, that I need to bound some parts of my new business logic with this older PHP website. I just need to call some simple Java methods (e.g. searching in db - pass on one or two parameters and get a result) from this PHP website. I've done some research and it looks like I should use Web services. There is a lot of materials for this topic in the web, but somewhere I've read, that web services are overkill for such the simple scenario. Is here any easier way to call Java business logic from PHP. Thank you very much for your answer.
Edited by: esembaJ on 13.10.2008 22:53

As I understood, your "application" consists of two parts: web site written on php and EJB+Struts.
If so, you can easily make HTTP requests from php to your Struts actions.
Your actions can make response in JSON (JavaScript Object Notation) with the help of json-plugin.
With these approach you beat two things: you can make actions which can be easily used asynchronously (JSON helps to do this) also they can be used by any application that can parse JSON response.
You don't need to dig into WS. Your case is very simple because of powerful java web-framework. WS will make your solution too complicated. Also you'll have troubles with WS on php-side.
Once, I've had to send some data to java-WS from php4. I've tried to realize it in many ways, but finally I've made simple HTTP request with manually formed XML-body (it was SOAP).

SOAP - Java & PHP

Hi all!
I am developing now a SOAP extension for my web. I am using nusoap.php for PHP. Now I have the WSDL file and would like to connect to the server with Java. With WSDL2JAVA I create the Java Classes, but I could't connect to the server. Can anyone post me a link for more information about this?
Thanks!

how did you solve this? I am having a similar problem :(

Java - php / passing parameters

hi,
i am trying to set up a communication between my java app and a php skrip. i've done the following:
try {
URL url =
new URL("http://test.net/" +
"login.php");
URLConnection connection =
url.openConnection();
connection.setDoOutput(true);
PrintStream out =
new PrintStream(connection.getOutputStream());
out.println("username=" + URLEncoder.encode("test"));
out.println("password=" + URLEncoder.encode("9e07480f0e4952926e115f15bc50ec47"));
out.close();
DataInputStream in =
new DataInputStream(connection.getInputStream());
result = in.readLine();
System.out.println("result:" + result.toString());
in.close();
} catch(MalformedURLException mue) {
System.out.println("Illegal URL: " + mue);
} catch(IOException ioe) {
System.out.println("IOException: " + ioe);
} catch(Exception e) {
System.out.println("Error: " + e);
the php gets my request but it doesn't realize the parameters username/passord.
is there a way to set the parameters through the api or do is the only way to do it by adding them to the url like ?username=bla&password=bla. i really would like to do it on a higher level but maybe there is no api support available. thanx for any advice, mischka.

Web hosting for ColdFusion, ROR, Java, PHP, MySQL

The company I currently use to host my web site supports PHP, MySQL, Ruby on Rails, but I don't think it supports ColdFusion, and I would imagine there are other things I could not put on my web site, such as EJB based Java apps.
My point is that does anyone know of a web hosting company that supports PHP, MySQL, Ruby on Rails, AND ColdFusion, AND anything else I might need to be able to practice using Flex to connect to data on the server using various technologies, like RemoteObject, WebService, etc.
The web hosting company must be reliable and stable as well.

I'd recommend you to get a dedicated server and setup there everything you need.

Array_reverse() in PHP -- ist it possible in JAVA?

Hello JAVA Community,
I'am a newbe in JAVA, an older C++/PHP Developer.
How can I do that in JAVA:
// PHP Code:
$input = array(3,4,6,6,7,8,9);
$result = array_reverse($input);thank you very much for your kind solutions..

Dear Aurelius,
thank very much but im am just looking of an "method", ist there any method or not? That is my question.There is not one built in by default, but I showed you both how to do it and how to make it specially built into the system for you.

It is just about a PHP function; I search for an equal function in Java.The answer simply could be "there is nothing something like that in Java".Do not worry; I am not angry with you.
I see that you have difficulty comprehending it, as you say. Based on your writing, it appears that English is not your first language. Is that correct? I did not realise this at first. I will assume any misunderstanding is due to this language barrier.

Someone else has pointed out that it does exist in Java, though it is for a different data structure and not specifically for an array.
You can put what I gave you into a method and call that, or you can use a Collection instead of an array and use the Collections reversal method that someone else mentioned.
One last thing, concerning terminology, just in case you did not realise it (I assume not since you write "method" in quotation marks) since you are used to dealing with C++ and PHP. The term method refers to a function which is a member of a class or object, and, since almost all data are objects in Java, all functions in Java are methods. Everyone around here will say method instead of function.
I hope all this helps you. Good fortune to you in your Java endeavors.

Missing fonts in Java

Reformated my XP SP3 computer and loaded Firefox 13.0.1 and Java from Oracle.
When I open any pages that have javascripted close X's on them I receive a square box with 27 over 16 in it instead of the X.
On one site the code reads:
font-family: "Helvetica Neue",Helvetica,Arial,Verdana,sans-serif;
<a href="javascript:return void(0);">✖</a>
(Not sure if that will show up at your end as a little box - or - a little box with the 27 and 16 in it).
I checked http://browserspy.dk and got a list of 45 fonts on Fonts Information - Detected via Flash (http://browserspy.dk/fonts-flash.php) but
only 36 on Fonts Information - Detected via Java (http://browserspy.dk/fonts-java.php)
Helvetica is missing from both lists.
These fonts are showing up on the Java page but not the Flash page.
Dialog
DialogInput
Lucida Sans
Monospaced
SansSerif
Serif
These fonts are showing up on the Flash page but not the Java page.
Arial Baltic
Arial CE
Arial CYR
Arial Greek
Arial TUR
Courier New Baltic
Courier New CE
Courier New CYR
Courier New Greek
Courier New TUR
Times New Roman Baltic
Times New Roman CE
Times New Roman CYR
Times New Roman Greek
Times New Roman TUR
Really not sure what to do about this.
Is there someway I can get Flash/Java to recognise these fonts?
Thank You

That is an Unicode symbol &#x2716;
If you see the hex code instead of the character then Firefox wasn't able to find a (dingbat) font that handles this character.

How Can i use the key file Generated by RSACryptoServiceProvider to encrypt with php?

I need to be able to encrypt data in PHP using a public key generate by .NET(RSACryptoServiceProvider). I will then decrypt the data later in C# using the private key.

As you see this code snippet is a xml format private key. at .net platform,which can use encrypt or dencrypt.
i have try the Extension Crypt RSA ( http://pear.php.net/reference/Crypt_RSA-1.0.0/elementindex_Crypt_RSA.html ) to help me encrypt data by php.but it haven't return a currect result. the data encrypted by php cann't dencrypt by c#.
does the RSA algorithm provider by Crypt_RSA can give a stand result as c#?
BTW :i just use the xmlkeystring like this.

Java won't work on Firefox, while it works on Safari on a Mac.

I have a MacBook Pro and downloaded Firefox 3.6 for it. Now I've realized that Java plugins won't work in Firefox for some reason, while they do work in Safari that came with the Mac. The problem wouldn't be with Java, since it works on Safari.
The Java-related plug-ins I have installed in Firefox are the Java Embedding Plug-in 0.9.7.3 and Java Plug-in 2 for NPAPI browsers.
When I go to a page that contains a Java applet, there is no error, the page says it's done loading, and there's a blank spot where an applet is supposed to be.

Actually, I have both plugins installed in Mac OS X 10.6, verified by entering '''about:plugins''' in the SeaMonkey 2 Location Bar (address bar)
Java Embedding Plugin 0.9.7.3
 File name: MRJPlugin.plugin
Java Plug-In 2 for NPAPI Browsers
 File name: JavaPlugin2_NPAPI.plugin
This is a new iMac computer I just set up last week running OS X 10.6.4 with all current Apple Software Updates. I have SeaMonkey 2 installed on it, but not Firefox.
I have Java 6 Update 20 ( 1.6.0_20 ) installed, verified by going to the test link in the KB article I posted above,
http://javatester.org/version.html
Java 1.6.0_20 (referred to as "Java for Mac OS X 10.6 Update 2" on the page cor-el linked) should be available from Apple's [http://support.apple.com/kb/HT1338 Software Update] feature.
Another test link you can try (from about:plugins):
http://browserspy.dk/java.php
I think that the Java Embedding plugin is something that Mozilla includes with all its current browsers (Firefox, SeaMonkey, Camino) based on: http://plugindoc.mozdev.org/OSX.html#Java
...which links to http://javaplugin.sourceforge.net/

Java was blocked due to the threat I have followed the update & other options to reenable it ie.manual updates reinstalls yet websites like YouTube still wont load up.Works fine in Chrome & IE!

Your plugins list in "more system details" shows Next Generation Java Plug-in 1.6.0_31 for Mozilla browsers so Java should not be blocked.
Could you post a link to a webpage where Java isn't working for you? YouTube uses Flash, not Java. Here is a list of Java test pages you can try, to confirm that Java is working, from http://kb.mozillazine.org/Java#Testing_Java
* [http://www.java.com/en/download/help/testvm.jsp Test your Java Virtual Machine (JVM)] at java.com.
* [http://browserspy.dk/java.php Java Information - BrowserSpy.dk]
* [http://javatester.org/ Java Tester] - The test pages at javatester.org will tell you if your web browser is enabled for Java and, if so, the Java version.
* [http://www.pinlady.net/PluginDetect/Java/ Java Plugin Detector]
By the way, I see in your plugins list that you also have the VLC media player Web Plugin 2.0.0 so, it's possible that the VLC plugin is causing a conflict if YouTube or other videos don't work. See [[Video or audio does not play]] (you may need to disable the VLC Media Player plugin in the Add-ons -> Plugins list for some media to play).

How to make sure an applet runs with Java 5?

Hi all,
First let me say thanks for all the help in the past. You've help me go from noob to intermediate noob. I've just about finished my first applet game which can be checked out here .
Now I've been reading about problems with mac and 1.6. (note it works on Linux). I want to make sure that it runs fine and of course I don't own a mac. So I downloaded the 5 JDK. Selected it as the java platform in Netbeans, compiled and it ran fine.
Questions:
Do I have to always use 1.5 to compile and perhaps set it as default?
Since it works in 1.5, do I compile it with 1.6 and just upload?
I'm worried I'm not testing it correctly. I mean if I have both 1.5 and 1.6 installed on my machine, how to I make sure the applet is only using 1.5 to run?
Thanks
Darrin

I haven't got a clue RE your problem other than for max-portability you should compile with [-target 1.5|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html].
I must say I'm impressed, except I suspect my PC must be substantially faster than any of your test platforms... can you throttle it to CPU performance somehow? Or maybe it's just that my reflexes aren't what they once where.Thanks.
There seem to be two issues. The first is what people are using. This web stats shows pretty poor penetration of 1.6.
[http://www.statowl.com/java.php|http://www.statowl.com/java.php] Penetration: 54% with JRE1.6 + 19% with JRE 1.5. Total 73%.
The second is I've read that mac and 1.6 do not get along except on a 64bit platform.
So for applets there is not much choice but to compile on 1.5 for the broadest user base. I guess the good news is 1.4 and earlier are almost non-existent.
