I've been struggling with this for a while and am finally resorting to

asking for help.

Below is the code that works in java:

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

import java.net.URL;

import java.util.Vector;

import org.apache.soap.Constants;

import org.apache.soap.Fault;

import org.apache.soap.SOAPException;

import org.apache.soap.rpc.Call;

import org.apache.soap.rpc.Parameter;

import org.apache.soap.rpc.Response;

import java.io.*;

import java.util.*;

public class TopXCall {

public static void main(String argv[]) {

try {

String endpoint =

"http://infao5501.ag5.mpi−sb.mpg.de:8080/soap/servlet/rpcrouter;

// Initialize the method parameters

Vector params = new Vector();

// Create the call.

Call call = new Call();

call.setTargetObjectURI("TopXService");

call.setMethodName("processQuery");

call.setParams(params);

call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

// Invoke the call.

Response response = null;

SOAP connection to Java Web Service from PHP

try {

response = call.invoke(new URL(endpoint), "");

if (response.generatedFault()) {

Fault fault = response.getFault();

System.err.println("Generated fault: " + fault);

} else {

System.out.println(response.getReturnValue().getValue());

}

} catch (SOAPException e) {

System.err.println("Caught SOAPException (" +

e.getFaultCode() + "): " + e.getMessage());

}

catch(Exception e) {

System.err.println("Exception caught: " + e.getMessage());

}

Now I'm trying to get it to work in PHP. I believe I need to create a

WSDL file since there was not one provided.

Below is my PHP code and attempt at a WSDL file. I coppied a sample

file and modified the parts to suit my needs ... obviously I have made

some errors.

Any help or advice would be greatly appreciated.

firefox port issues

2010-05-05T12:30:00.001+05:30

The built in webserver in Visual Studio 2005, formerly known as Casini, uses a dynamic or static port on the localhost machine (e.g. http://localhost:2049/default.aspx).

It is dynamic by default, but you can make it static if you choose. That works very well except when you try it in Firefox. It simply gives you this response:

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has cancelled the request for your protection.

It does that by default whenever you use a port other than port 80 - the default website port. It took me a lot of digging to find the solution and here it is.
- Open Firefox

- Type about:config in the address field

- Right click anywhere on the screen

- Click new > string

- Enter preference name as: network.security.ports.banned.override

- Enter string value as: 2049 (or whatever port number you want)

2. Goto the jbossweb-tomcat55.sar inside that deploy folder.
3. Find the file named server.xml inside that folder. (tomcat service file).

Hibernate

2009-11-20T12:48:00.004+05:30

1. First create project in eclipse(either java project/webproject)
2. configure the required jar for sql or mysql or any data base
2. right click on project and Add hibernate capabilities
3. then configure the hibenate configureation file

<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="connection.url">jdbc:mysql://localhost:3306/frameworkdb</property> <property name="connection.username">root</property> <property name="connection.password">12345678</property> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.show_sql ">true</property> <property name="hibernate.hbm2ddl.auto">update</property> <mapping resource="authentication.hbm.xml"> </session-factory> </hibernate-configuration>

4. create the POJO code that will map the table column names eg.

5. create the mapping xml called authenticate.hbm.xml

6. create main class to run hibernate as standalone

package com.hib.showcase;    import org.hibernate.Query;  import org.hibernate.Session;  import org.hibernate.SessionFactory;  import org.hibernate.Transaction;  import org.hibernate.cfg.Configuration;    import com.hib.to.Authenticate;    public class FirstHibernateprg {     /**    * @param args    */   public static void main(String[] args) {       Session session=null;     try{       SessionFactory sessionFactory = new          Configuration().configure().buildSessionFactory();              session =sessionFactory.openSession();             Transaction tr= session.beginTransaction();       Authenticate auth=new Authenticate();       String sql="delete from authentication where uid=6";       Query qq=session.createQuery(sql);       auth.setUid(6);       auth.setUserName("praveen");       auth.setPassWord("007");         //session.save(auth);       qq.executeUpdate();       tr.commit();           }catch(Exception e){      System.out.println("error : "+e.getMessage());      e.printStackTrace();     }finally{      session.flush();       session.close();           }   }    }

7. run the application as like normal standalone java class

Struts Tutorial Page (Rose India)

2009-03-30T09:15:00.003+05:30

Difference between Model 1 and Model 2 architecture:

Features of MVC1:

Html or jsp files are used to code the presentation. To retrieve the data JavaBean can be used.
In mvc1 archictecture all the view, control elements are implemented using Servlets or Jsp.
In MVC1 there is tight coupling between page and model as data access is usually done using Custom tag or through java bean call.

Features of MVC2:

The MVC2 architecture removes the page centric property of MVC1 architecture by separating Presentation, control logic and the application state.
In MVC2 architecture there is only one controller which receives all the request for the application and is responsible for taking appropriate action in response to each request.

Struts framework provides three key components:

A request handler provided by the application developer that is used to mapped to a particular URI.
A response handler which is used to transfer the control to another resource which will be responsible for completing the response.
A tag library which helps developers to create the interactive form based applications with server

see the link given below, you will find the tutorial for the struts and it will help u to learn from the beginning

Connection pooling in JBOSS with MYSQL

Step 1 : copy mysql-connector-java-5.0.7-bin.jar into jboss/server/default/lib or jboss/server/all/lib
Step 2 : config the data sources with mysql-ds.xml and config the login-config.xml.
Mysql-ds.xml

Login-config.xml

Step 3: then create your connection pooling class in java

Step 4 : create the remaining class and deploy it into jboss as war file, in jboss/server/default/deploy/ ______.war file.

creating webservice using wsgen

2008-09-21T07:40:00.000+05:30

create your interface and implement your interface with your webservice class

and create your class

then open command prompt and select ur class...

1. to create jaxws--- wsgen -cp yourpackage.implementationclass

eg. wsgen - cp com.test.ws.Sampleimpl

it will create artifacts then create service name and then create the client class

2. wsimport -p package.implementationclass wsdl

eg. wsimport -p com.test.ws.Sampleimpl http://localhost:8080/SampleWs/SampleWsService?wsdl
