Exposing an Axis1 service through WSO2 WSAS

Do you want to make use of the powerful QOS features of Axis2 with your legacy Axis1 applications? Yes it is possible with WSO2 Web services application server. It allows easy deployment of any Apache Axis1-based Web service and engage advanced WS-* services, such as WS-RM and WS-Policy in front of legacy Axis1 services.
Lets see how we can use this cool feature.

Step 1

Write the service impl class.

package org.wso2.wsas.service;

public class Calculator{

public int addition(int x, int y){
return x+y;
}

public int multiplication(int a, int b){
return a*b;
}

public int subtraction(int c, int d){
return c-d;
}

public double division(double m, double n){
return m/n;
}
}

Compile and make a jar with the above class. Suppose it is Axis1resources.jar

Step 2

Write the deployment descriptor (*.wsdd) for your service impl class and save it as calculator.wsdd

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="Axis1calculator" style="wrapped">
<parameter name="className" value="org.wso2.wsas.service.Calculator"/>
<parameter name="allowedMethods" value="*"/>
</service>
</deployment>

Step 3

Start WSO2 WSAS (If you haven't downloaded it yet, get it from http://wso2.org/projects/wsas/java

Access WSO2 WSAS management console using https://localhost:9443 (Default admin user credentials are admin/admin)

Go to Services and service group management page and click on "Upload Axis1 service" link. You will be directed to the following page



Browse for the above calculator.wsdd and Axis1resources.jar and click on Upload. Axis1 service will be deployed on WSAS and you will get a confirmation message.

Step 4

If the deployment is successful, you will see the Axis1 service is shown in the services and service group management page.
Click on "Axis1calculator" service.
In the "Service Management" page, select "Tryit"
Invoke service using some inputs and see the output.

Working with HTTP multipart requests in soapUI

Image
You can use HTTP request test step in soapUI to submit messages with various Content-Types.  In this post, we will have a quick look into the multipart/form-data requests in soapUI. multipart/form-data requests usually come into action when you do HTML form submissions with file attachments. For example, have a look at the following HTML form post. <form action="http://localhost:8090/CKFileUploadApp/UploadServlet" method="post" enctype="multipart/form-data"> <input type="file" name="file"> <input type="text" name="paramName"> <input type="submit" name="Submit" value="Upload File"> </form> In the forms like above, we have file upload option as a form input where we can upload a file along with the form submission. In that case, the request's HTTP content type will be multipart/form-data. How can we simulate such a request using soapUI

Common mistakes to avoid in WSO2 ESB - 1 - "org.apache.axis2.AxisFault: The system cannot infer the transport information from the URL"

In the next few weeks, you could expect a series of blog posts from me which explain the remedies to avoid some common mistakes which we do when working with WSO2 ESB . This is the first of many. During the initial rounds of testing your integration solution or even in production systems, you may have come across the following error. org.apache.axis2.AxisFault: The system cannot infer the transport information from the URL .... Some of you may have struggled hours figuring out a solution to address this issue. Let me explain this error in detail and possible causes of this. So, next time when you see this error in your WSO2 ESB setup, you will not have to spend time unnecessarily googling everywhere. There can be many different causes of this error. I have observed  four main reasons. Cause 1 This is the simplest cause. Suppose, you have a proxy service similar to the following. <proxy xmlns="http://ws.apache.org/ns/synapse" name="MistakesTest&q

How to deploy JSR181 annotated class in Apache Axis2

Image
JAX-WS (Java API for XML Web Services) provides support for annotating Java classes with metadata to indicate that the Java class is a Web service. With the annotations, you can expose java classes as web services with minimum effort. Apache Axis2 ships with JAX-WS support since its 1.4 release. This post explains the simplest possible scenario of JAX-WS support, how you can deploy an annotated class in Axis2. Pre-requisites Apache Axis2-1.4 or later JDK1.5 or above Step 1 Write an annotated class as follows. package org.apache.axis2; import javax.jws.WebMethod; import javax.jws.WebService; @WebService public class Calculator { @WebMethod public double Add(double x, double y){ return x+y; } } Here, the @WebService annotation tells the server runtime to expose all public methods on the above class as a Web service. Also, with the @WebMethod annotation, you can specifically denotes the methods which are exposed in the web service. Step 2 Package the above class as a JAR (
