SOAP Overview
SOAP is a protocol for invoking methods on servers and exchanging structured information. It uses XML and HTTP to define an envelope, encoding rules, and conventions to represent method calls and responses. SOAP allows applications to communicate over a variety of underlying protocols and platforms and is simple, extensible and independent of any programming model.
Simple Object Access Protocol
This document discusses Simple Object Access Protocol (SOAP). SOAP allows applications to exchange information over HTTP and is independent of platform and language. A SOAP message contains an envelope, header, body, and optional fault. The envelope defines the message as SOAP. The header contains application-specific metadata. The body contains the call and response. Fault indicates any errors. SOAP uses HTTP for transport and is XML-based, allowing it to penetrate firewalls.
Advanced soa and web services
Handlers are components that can intercept and process incoming and outgoing web service messages. There are two types of handlers - protocol handlers that work on SOAP headers and bodies, and logical handlers that work on message payloads independent of protocol. Handlers are used for tasks like logging, monitoring, and throttling. For interoperability, issues can arise from data type mismatches, platform differences, and inconsistencies in how SOAP headers and bindings are implemented across platforms.
Soap.doc
SOAP is a protocol for exchanging XML-based messages over networks, normally using HTTP/HTTPS. It allows applications to communicate in a decentralized and distributed environment. A SOAP message contains an envelope element with a header and body. The body contains the call and response information while the header contains optional metadata. SOAP uses XML schemas to define the structure and content of messages to ensure interoperability.

It describes the key components of a SOAP message including the envelope, header, body, and fault. It also explains how SOAP uses XML to define messages in a platform and language independent way to enable communication between applications.
soap
SOAP is a lightweight protocol for exchanging information in a distributed environment. It uses XML to define an envelope, encoding rules, and conventions for representing remote procedure calls and responses. SOAP allows methods to be invoked over HTTP by specifying the method name in the HTTP header and placing the method call in the HTTP payload encoded as XML. Responses return the result encoded in XML in the HTTP response payload.
Putting SOAP to REST
The document compares SOAP and REST web services. SOAP uses XML envelopes and defines standards like WS-Security, but requires more complex infrastructure. REST uses a simpler architecture based on HTTP methods, is more lightweight and performs better. It supports multiple representations like JSON and is easier to build, maintain and test. While REST provides less standardized enterprise features, it enables more scalable and cacheable solutions.
Web Services Part 2
The document describes how to create a simple web service in Java that returns a greeting message, and then how to test and consume the web service using a client. Key steps include:
1. Creating a Java class with the @WebService annotation to expose a "sayHello" method.
2. Deploying and testing the web service by invoking the "sayHello" method and viewing the request/response messages.
3. Generating a WSDL file from the web service.
4. Creating a client project and using the WSDL to generate a client to invoke the "sayHello" method.
Architecting Web Services
The document discusses various aspects of architecting web services including why they are used, common service types like RPC, SOAP and REST, how to deliver different service types, considerations for machine-readable formats, error handling, asynchronous handling and more. It provides examples of WSDL definitions, SOAP requests and responses, and recommendations for building robust web services.

Introduction to SOAP
SOAP is a standard protocol for exchanging XML-based messages over computer networks, normally using HTTP/HTTPS. It allows applications to communicate in a decentralized and distributed environment. Key points:
- SOAP specifies how to encode an HTTP request and response so it can convey a message. This allows different systems to communicate even if they use different technologies.
- A SOAP message contains an envelope specifying the message structure and a body containing the message payload. It may also contain a header for things like authentication.
- SOAP is language and platform independent - it can be used by any programming language or system that can produce and process XML. Major vendors provide SOAP integration and tools.
Servlet/JSP course chapter 2: Introduction to JavaServer Pages (JSP)
This chapter introduces JavaServer Pages (JSP) technology which allows creating dynamic web content that combines static and dynamic components. A JSP page is a text document that contains static data in any text format along with JSP elements that generate dynamic content. When a request comes in for a JSP file, the JSP compiler generates a Java servlet class file that handles the request. An exercise demonstrates developing a basic web application using JSPs to display a submitted form entry. The key differences from servlets are that JSPs have a simplified syntax and the response is implicit rather than needing to be explicitly written out.
Improving Soap Message Serialization
SOAP web services are slower than other technologies like RMI and Remoting due to the overhead of XML processing and serialization to text format. Template generation and caching of SOAP messages can help improve performance by reducing serialization costs. The document discusses generating SOAP message templates from a WSDL file and implementing caching of templates and SOAP envelopes on the client side to gain performance improvements, especially for requests with complex objects.
fffSeminar
The document discusses Simple Object Access Protocol (SOAP), which is an XML-based protocol for exchanging structured information between peers in a decentralized, distributed environment. It defines an envelope structure that provides a framework for describing what is in a message and how to process it. Key components of the SOAP message include the envelope, header, body, and optional attachments. The SOAP architecture supports different roles in web services including service providers, brokers, and requestors.
Web-Services!.pptx
This document discusses key concepts related to web services including SOAP, WSDL, and UDDI. It defines a web service as a service available on the web that enables communication between applications. It explains that SOAP is a standard protocol for communication and WSDL provides an XML interface that describes a web service's location, methods, and data types. UDDI allows service providers to publish their WSDL files so consumers can discover and access available web services.
SCDJWS 3. WSDL
WSDL (Web Services Description Language) is an XML format for describing web services and how they can be accessed, with definitions for the data types, messages, operations and bindings. It has two layers - a service definition layer that describes operations and messages, and a binding layer that specifies protocols and data formats. An example WSDL document is provided that shows the typical structure and elements used.

2. wiring beans
The document discusses dependency injection (DI) in Spring, including wiring objects together through constructors and setter methods, creating beans with different scopes, and injecting properties, references to other beans, lists, sets, maps, and properties. Objects have their dependencies provided by the Spring container rather than constructing or looking up dependencies directly. Beans can be constructed in various ways including with default constructors, parameterized constructors, and factory methods.
Design Pattern 5. Singleton Pattern
The document discusses the singleton pattern, which ensures that only one instance of a class is created. It is a design pattern that restricts the instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The singleton class contains a private constructor and a public static method that allows access to the sole instance.
SCDJWS 6. REST JAX-P
The document summarizes several XML processing technologies:
1. REST defines architectural principles for designing web services focused on system resources transferred over HTTP using a limited set of verbs like GET, POST, PUT, DELETE.
2. JSON supports serialization of data structures and can be dynamically executed as JavaScript.
3. SAX, DOM, XSLT, and StAX are Java APIs for XML processing that provide event-driven and tree-based access to XML documents. SAX is push-based while DOM constructs an in-memory tree representation.
SPRING 1. overview
Spring is a dependency injection container that manages the lifecycle and dependencies of components in an application. It supports loading configuration from XML files located in the classpath or file system using application contexts like ClassPathXmlApplicationContext or FileSystemXmlApplicationContext. Spring provides modules for aspects, data access, messaging, and testing that add functionality beyond the core container. Dependency injection allows objects to have their dependencies provided at creation rather than creating them directly, which makes the code loosely coupled, readable, and easy to test.

3. Key aspects of the request and response objects are outlined, such as accessing headers, cookies, and input/output streams.
SCDJWS 5. JAX-WS
JAX-WS simplifies application development through support of a standard, annotation-based model to develop Web Service applications and clients. It replaces remote procedure calls defined by JAX-RPC and allows developers to write message-oriented and RPC-oriented web services. JAX-WS uses platform-independent technologies like HTTP, SOAP and WSDL and provides tools for generating artifacts and importing WSDL definitions.
SCWCD 1. get post - url (cap1 - cap2 )
The document provides an overview of key concepts in web development including HTTP methods (GET, POST), the servlet lifecycle, the web container, the web.xml deployment descriptor, and URLs. It describes the benefits and features of GET and POST requests, how the container manages servlets and JSPs, how the web.xml file configures servlets without code changes, and the components of a URL.
Design Pattern - 2. Observer
The document discusses the observer design pattern. It defines interfaces for subjects and observers. The subject interface defines methods for registering, removing, and notifying observers. The observer interface defines an update method. A display element interface defines a display method. It provides class diagrams and implementations of subjects and observers using built-in Java classes to demonstrate how the observer pattern works.
SCDJWS 4. UDDI
UDDI is a web service that allows publishing and finding information about web services. It uses SOAP over HTTP and supports two main functions - inquiry to search registry data and publish to add/modify/delete data through authenticated requests. The UDDI registry stores four main types of data - business, business services, binding templates, and tModels.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

- 34. SOAP elements must not have attributes belonging to the same namespace asthe SOAP <Envelope> element ( http://schemas.xmlsoap.org/soap/envelope/ ): <Envelope>, <Header>, <Body>
- 36. A receiver of a SOAP message that contains a mandatory header block targeted at the receiver, using the soap:role attribute in the header block, must generate a “soap:MustUnderstand” fault if the receiver does not understand the header block
- 37. When a fault is generated, the receiver should not perform any further processing of the SOAP Envelope, except for any processing required to roll back the effects of the processing of the SOAP Envelope up to the point of the fault.
- 38. If the normal processing of a SOAP Envelope would have resulted in a SOAP response being sent, a receiver must transmit a fault in place of the response if a fault is generated.

- 51. Extensibility can be used to add capabilities found in richer messaging enveroiment
- 54. Possible reasons for faults may be improper message formatting, version mismatches, trouble processing a header and application-specific errors
- 55. A SOAP fault is generated by the node, be it an intermediary or the ultimate receiver
- 56. If the messaging exchange pattern One-Way is used, then the SOAP fault must not be transmitted to the immediate sender. The SOAP fault may be stored somewhere
- 76. Handlers are invoked with a message context , which provides methods that the handler uses to access and modify inbound or outbound messages.
- 79. handleFault() is called when a message contains a protocol fault.
- 80. close() is called after the completion of message processing by all handlers for each web service invocation,
