Java techlogies versus PHP

Hello,
we will have big web project. And now I must choise techlogies. All projects were create with PHP.
Now I think change technology, because I think PHP will small for this project. This project can have more that 1000 users one time. This site will have chat system, and users will often make requests.
Can I say, what Java will be better decision in this project?
Can you give examples where Java better in big projects?
I think about servlets and EJB.
I will be grateful for answers.

PHP or Java?
The basic difference between Java and PHP is that with Java you can have actual object model underneath - n-tier application. That comes handfull when you handle a lot of users and various datasources.
Another thing is that with use of object models like EJB or COM+, .NET you can use transaction framework already built into the system or object pooling (Here maybe I can mention connection pooling - in PHP I think each page opens its own connection (In java the same connection can be used by many clients)). I won't mention the separation od data and business logic in this level.
In general you also can test the whole application, which I'm not sure if you can with PHP.

Java Front End, PHP Back End

Hi all, I am trying to create a java front end with a php back end. Using a tip from Core Java Technologies Tech Tips (http://java.sun.com/developer/JDCTechTips/2004/tt0210.html#2). I tried to convert their code from a command line to a GUI and have gotten preaty far but it is only allowing me to get one row of data from the php file. Here is my code so far:
package test;
import java.net.URL;
import java.net.MalformedURLException;
import java.net.URLConnection;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;
* @author bdeonline
public class test extends javax.swing.JFrame {
private static URLConnection connection;
private String inputLine;
private static void connect( String urlString ) {
try {
URL url = new URL(urlString);
connection = url.openConnection();
} catch (MalformedURLException e){
} catch (IOException e) {
private String readContents() {
BufferedReader in = null;
try {
in = new BufferedReader(
new InputStreamReader(
connection.getInputStream()));
String inputLine;
while (
(inputLine = in.readLine()) != null) {
return(inputLine);
} catch (IOException e) {
return inputLine;
/** Creates new form test */
public test() {
initComponents();
/** This method is called from within the constructor to

exitForm(evt);
jButton1.setText("jButton1");
jButton1.addActionListener(new java.awt.event.ActionListener() {

jButton1ActionPerformed(evt);
getContentPane().add(jButton1, java.awt.BorderLayout.SOUTH);
jScrollPane1.setViewportView(jTextArea1);
getContentPane().add(jScrollPane1, java.awt.BorderLayout.CENTER);
pack();
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
connect("http://localhost/test.php");
jTextArea1.setText(readContents());
/** Exit the Application */

new test().show();
// Variables declaration - do not modify

// End of variables declaration
I am preaty new at java, I know PHP preaty well though so something like this could help me out alot. Most of this code was generated with the help of Netbeans.

I dont see why it would unles it has something to do with your URLConnection being static. setText() is only going to give you one line as well. try
jTextArea.append(inputLine);
and make only one declairation of inputLine.
The only thing that should be static in your code is the main method.

Java sha1 and PHP sha1

Hello to everyone.
When encoding with PHP using sha1 i do not get the same result as Java's sha1 encoding.
For example encoding letter 'e' in PHP produces:
58e6b3a414a1e0[b]90dfc6029add0f3555ccba127f
whereas in Java it produces:
58e6b3a414a1e0[b]3fdfc6029add0f3555ccba127f
Below is the code i am using for both Java and PHP
String password=pass;
          java.security.MessageDigest d =null;
          try {
               d = java.security.MessageDigest.getInstance("SHA-1");
          } catch (NoSuchAlgorithmException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          d.reset();
          d.update(password.getBytes());
          String secret = new String (d.digest());
          secret.getBytes();
          StringBuffer sb = new StringBuffer(secret.getBytes().length * 2);
        for (int i = 0; i < secret.getBytes().length; i++) {
             int b = secret.getBytes() & 0xFF;
sb.append(HEX_DIGITS.charAt(b >>> 4)).append(HEX_DIGITS.charAt(b & 0xF));
return sb.toString();
PHP Code:
$str = 'e';
$str2=sha1($str2);
echo $str2;Anyone had similar problems and found a solution to them? I cannot see any mistake in the code so any help would be much appreciated.
P.S: I am running Java 1.4 and PHP 5.1.6 configuration
Kind Regards

Hi,
I found your reply regarding "Java sha1 and PHP sha1" on the forum and would like to ask another related question.
I use the following statement to insert username/password to the database:
INSERT INTO [db_Report].[dbo].[tblLogin]
([USERNAME]
,[PASSWORD])
VALUES
('test'
,HashBytes('MD5', 'password'))
GO
In my Java code, however, the following method always return false. I noticed that in the database
HashBytes('MD5', 'password') returns "0x5F4DCC3B5AA765D61D8327DEB882CF99"
while
The the encrypted login password is "[B@13d93f4" in the Java code.
In this case, how should I check the password, using MessageDigest or not ?
Many thanks.
===============
     {code}private static boolean authenticateUser(String username, String loginPassword){
          boolean authenticate = false;
          Connection con = getDatabaseConnection();

Edited by: arun240 on Jul 25, 2008 8:47 AMWell, it seems there's an object (perhaps a PaymentPipe?) pointing to null which you're trying to invoke a method (performPaymentInitialization()?) on. Needles to say: you can do that.
SomeObject so = null;
// ... some more code ...
so.someMethod(); // No can do! A NPE will be thrown!

EJB+JSP versus PHP

What is the advantage of using EJB+JSP for a web ticket selling application instead of using PHP?
Can Java support more customer hits compare to PHP?
Is EJB+JSP better than PHP? Why?

I know both PHP and Java. PHP is a more rapid development tool than Java. Once you know it, it is just easier to make simple pages out of it vs Java. In some ways PHP is easier to develop in and in some ways it is harder.
There is no real IDE for PHP. There are some tools for real time syntax checking (Komodo) and debugging, but they are not as mature as the pick of current Java IDE's.
In reverse, there is never a need to restart a server when updating a php file unlike Java. This is not a problem with JSP's, but when you change servlets the server will unload all classes from memory and reload. This is a major pain if you are working on a production server.
I have created a game clan site with many functions using PHP and an order processing section of someones web site. It is fine for smaller projects and is very fast to develop in, however PHP does not scale as well as Java. A large enterprise system is better suited to using Java.
Also, PHP is a loosely typed language. This has many nuances that are different from a strongly typed language like java. OOP is definately not as powerful in PHP, as there is no private, protected and public typing of methods and fields. You can make classes and even extend classes, but it is poorly implimented IMO. I did all my PHP OOP style, but did not use any inheritance. The limitations of OOP principles is probably the most restrictive aspect of PHP that I can see.

One thread is enough.

You could have bumped it instead. Also, you still just posted a junk of unformatted stuff. Furthermore, for HttpClient support ask at an HttpClient mailing list of rorum.

Problem in creating a java proxy for PHP web service

This is a problem in generating a java proxy for a PHP webservice.
I have a PHP service running on Wamp Server and also a PHP client which is able to call the service.
The WSDL for the PHP web service is also generated .
I am trying to create a java proxy using the jdev (10.1.3.0.3) from the wsdl file.

This is a problem in generating a java proxy for a PHP webservice.
I have a PHP service running on Wamp Server and also a PHP client which is able to call the service.
The WSDL for the PHP web service is also generated .
I am trying to create a java proxy using the jdev (10.1.3.0.3) from the wsdl file.
The wsdl generated by the php program is

Java httpservlet and php

Hi.
I'm trying to work out an interface in php for a java http servlet. But i have some problems when i try to redirect my response to the php page.
Any idea how i can do this (or if i can do this)?

You cannot redirect the response once output has been
written to it.
You may need to redirect client side, with meta
refresh or javascript.I haven't written anything in the output.
My servlet is quite simple: it takes some params from the user, does some work with them, and then encapsulate them as attributtes/params for the response. Normally I would write this:
this.getServletContext().getRequestDispatcher("/gate.jsp").forward(sreq, sres);after i'm done with my processing.
I was wondering what must I do/use to have the "response" redirected to another address like:
http://second_server/index.php.As far as I read, I cannot do this with the code line written above. I haven't found any example on how to do this, and, as I have said, I think it's possible (basically it's just working arround the HTTP), but I don't know how to do it....

Java SOAP and PHP server

HI all, I have the follow problem:
I have created a SOAP server with PHP. The client connection with PHP and with generated local classes for Java, with java.apache.axis.wsdl.WSDL2Java, is working very well and I don't have problems with this.
But now I try to use my API with the normal calls from JAVA with the direct Call without local classes:
Here are any sniplets:
My Method in the wsdl file:
- <xsd:complexType name="MyMethodRequest">
- <xsd:all>
<xsd:element name="username" type="xsd:string" />
<xsd:element name="password" type="xsd:string" />
<xsd:element name="partnerid" type="xsd:int" />
<xsd:element name="signkey" type="xsd:string" />
</xsd:all>
</xsd:complexType>
- <operation name="MyMethod">
<soap:operation soapAction="urn:MyURN#MyMethod" style="rpc" />
- <input>
<soap:body use="encoded" namespace="urn:MyURN" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</input>
- <output>
<soap:body use="encoded" namespace="urn:MyURN" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</output>
</operation>
The definition in the PHP file look like this:
$server->wsdl->addComplexType(
'MyMethodRequest',
'complexType',
'struct',
'all',
array(
'username' => array('name' => 'username', 'type' => 'xsd:string'),
'password' => array('name' => 'password', 'type' => 'xsd:string'),
'partnerid' => array('name' => 'partnerid', 'type' => 'xsd:int'),
'signkey' => array('name' => 'signkey', 'type' => 'xsd:string')
The server function is recieving an array with all this paramethers:
function MyFunktion($member)
// do anything
Also the Java code:
String method = "MyMethod";
Object[] member = new Object[] {username, password, partnerid, signkey};
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName(new QName("urn:MyURN", method));
call.setSOAPActionURI("urn:MyURN#MyMethod");
call.setUseSOAPAction(true);
call.addParameter( "member", XMLType.SOAP_ARRAY, ParameterMode.IN );
call.setReturnType( XMLType.XSD_BOOLEAN );
Object[] params = new Object[] {member};
Boolean ret = (Boolean) call.invoke(params);
System.err.print(" " + ret);
System.err.println();
I compile the class and when I start it, I don't send any data to the server, but why??? What do I made false? The server don't gives an error, but he dont recieve any data from me!
Thanks for every help:-)
Best Regards
Nik

Is Java better than PHP ?

Hi
I see that many large companies on the web which have large websites with a lot of traffic are choosing to use application servers for their sites. Usually the ones they are choosing are j2ee based application servers. I almost never see any large website with a PHP solution, it usually uses servlet/JSP. When i look at smaller sites its usually PHP. What i am wondering is why the large companies choose to use a complex setup of application servers when they could just set up a CMS in PHP which they could just buy from some place, install easily and then they could just start writing articles for example. Why does large companies use this complex solution of application servers instead of PHP which would be a much simpler setup... is it because PHP doesnt scale as well as java or what is it ?
Could someone please comment on this...

What i am wondering is why the large companies choose to use a complex setup of application servers when they could just set up a CMS in PHP which they could just buy from some place, install easily and then they could just start writing articles for example.Not all "large" websites are mere CMSs. Of the CMS solutions, the best ones do not run under PHP, thus not all CMS based websites choose PHP.
Why does large companies use this complex solution of application servers instead of PHP which would be a much simpler setup... is it because PHP doesnt scale as well as java or what is it ?The advantages of PHP are that it is free, easy to understand for beginners, and simple for small applications. It's a natural choice for inexperienced developers.
The advantages of Java/J2EE are that it is well supported, very structured, and has a massive library of standard and external libraries to support it.
What's PHP's answer to messaging solutions? To linear programming? To integration with legacy systems? It may well be that PHP doesn't scale, but that's the least of its problems in the enterprise world.
Your questions sounds suspiciously like "I like PHP, why is Java so complicated?" and the answer is "The complexity exists because sometimes we need it."
(Edited ambiguity in opening para).

Accessing Java HttpServer from PHP;

Hello all,
I have created an httpserver using 'com.sun.net.httpserver'. Everything works fine except one thing.
When i make this simple call from PHP (http://localhost:8081/something outputs an XML file):-
$url = 'http://localhost:8081/something';
$xml = simplexml_load_file($url);
print_r($xml); Nothing appears and it times out after sometime.
However, while the browser is 'trying' to get the result (from PHP file) if i 'stop' my HttpServer (Java) the result suddenly appears. I am very sure i close all the streams i opened. Does anyone have any idea?
Thanks
Neville

So on doing some debugging i realized that the http thread that started executing may have not exited correctly. That may explain the fact that when i shut the java server down explicitly while the 'php' code waits for some response, the response suddenly appears.
While creating the server i am using:-
server.setExecutor(Executors.newCachedThreadPool());In ThreadPoolExecutor.class
Runnable getTask() { ....
if (state == SHUTDOWN) // Help drain queue
    r = workQueue.poll();
else if (poolSize > corePoolSize || allowCoreThreadTimeOut)
    r = workQueue.poll(keepAliveTime, TimeUnit.NANOSECONDS);
else
   r = workQueue.take();
if (r != null)
    return r;
if (workerCanExit()) {
...Using the debugger tool took me to the class ThreadPoolExecutor.class which seems to be the bottleneck; This condition is true (poolSize > corePoolSize || allowCoreThreadTimeOut(=false)) and it starts polling. I think maybe this is causing the problem and if it exited maybe the result would appear. Even if the corePoolSize is more than poolsize it seems to be getting stuck in r = workQueue.take();.
I dont know how it works ok with a browser but hangs when PHP request comes into the picture. Strange...
Thanks
Neville

Java Desktop versus Enterprise client

What is the difference between Java Desktop Application versus Enterprise Applciation client?

Desktop Applicatoin is local to your computer, it may have connections to the network, such as MS-Word will connect to the internet for updates and help files.
An Enterprise Application is developed on multiple tiers--local clients, web servers, data servers, and etc. Processing done in an enterprise Applicatoin is distributed amoungst the different tiers.

I would like to know how to do this process. I would like my students to complete the module and then enter there name in the certificate line. Then have them enter their email address so that the certificate can be emailed to them and they can print it off. I would like to have the certificate be a PDF file so they cannot alter the name of the person who took the course.

Java BluePrints versus Jakarta

I created a new Visual Web Pack Application, for source structure I chose Jakarta (the other option is Java BluePrints), because I am going to deploy my application in Tomcat 5.5.17. For server I obviously chose Tomcat 5.5.17.
Also, I added the BluePrints AJAX components 0.1.1 to the component libraries of my project.
However when I wanted to drag an Auto Complete Text Field on one of my project's page this turned out to be impossible. I guess because I chose Jarkarta as source structure instead of Java BluePrints.
Does anyone know how to solve this problem?
What are the consequences of choosing Java BluePrints as source structure when you want to deploy in Tomcat?
Thanks,
Annet.

Well, the String.replaceAll(String, String) method uses the Java regexp internally, and I'm not sure there's a way to change that. So that at least is one place that will use it. I don't know for sure, but Jakarta's ORO is supposed to be fully compatible with Perl 5, and also supports other regexp types as well, so if you need that aspect of it, then go with Jakarta. I heard some of Java's are a little limited in some capabilities. I can't find any particular pages that refer to any comparisons of them at to compare runtime performance.

JSP versus PHP

Is there anything JSP does better than PHP?

PHP is a good scripting language, probably the best one. It does the same job as ASP only much better. I would suggest that JSP can actually do a whole lot more than that because you have the full functionality of the programming language behind it rather than being purely designed for web scripting. This gives flexibility and the jsp/servlet/bean architecture also offers far greater options for re-use and extension than php offers.
