3. What are the components of web service?
Answer:
Web services components are:
- SOAP- Simple Object Access Protocol
- UDDI- Universal Description, Discovery, and Integration
- WSDL- Web Service Description Language
- RDF- Resource Description Framework
- XML- Extensible Markup Language
Let us move on to the following Java web services interview questions.
4. What is XML-RPC? What are the features of XML-RPC?
Answer:
XML-RPC is nothing but an XML-based protocol. It is a straightforward protocol to exchange information between two devices over a network. Dave Winer created the XML-RPC protocol in 1998.
- XML Response is embedded in HTTP response.
- XML is considered Platform independent.
- XML helps in communicating between two different applications.
- XML-RPC uses HTTP protocol to send information between client and server devices
- RPCs are performed using simple XML language.
5. Explain Java API for XML Messaging (JAXM).
Answer:
- JAXM is a SOAP 1.1-based standard to send XML documents over the Internet from the Java platform.
- JAXM can be extended to work with higher-level messaging protocols by adding the protocol’s functionality to the SOAP.
Part 2 – Java web services Interview Questions (Advanced)
Let us now have a look at the advanced Interview Questions.
6. What is JAX PACK? Explain?
Answer:
Java API is for XML pack; it integrates all the programming interfaces by SUN for different web services development. JAX Pack is a bundle of JAXB, JAXM, JAX-RPC, and JAXR. Jax pack includes the documentation for support for the SAX and DOM.SOAP, WSDL, XSLT, EBXML, and UDDI standards. Developing Web Services with Java APIs for XML (JAX Pack) provides exhaustive coverage of Sun’s recently released JAX Pack.
7. Explain Web Service Architecture.
Answer:
Every application or framework needs some architecture to ensure the application is working as designed. It is the operations between two applications running on different platforms and frameworks supported by a different web service standard. In this architecture, we can see three different roles.
- Provider
- Requester
- Broker
Provider: The provider will create the web service and ensure it’s always available to the client application whenever a client wants to use it.
Requester: Requester is the client application; it needs to contact a web service.
Broker: Broker is the application it provides access to the UDDI.
Let us move on to the following Java web services interview questions.
8. Can you explain what UDDI, Disco, and WSDL are?
Answer:
UDDI: Universal description discovery and integration. It’s a directory used to publish and discover public web services.
DISCO: Disco is Commonly known as Discovery. Discovery clubs together standard services and exposes a schema document of the web services.
WSDL: Web Service description language.
9. Explain a few tools that help in testing web services.
Answer:
- SoapUI
- REST client
- JMeter
10. What is SOAP, and give a few advantages to it?
Answer:
SOAP: Simple Object Access Protocol. It is an XML-based protocol that helps in accessing Web services.
- WS Security
- Language-Independent
- Platform Independent

Break or return from Java 8 stream forEach?
Feb 07, 2025 pm 12:09 PM
Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Java Program to Find the Volume of Capsule
Feb 07, 2025 am 11:37 AM
Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
