SOAP is a protocol used for information exchange in distributed computing environment and SOAP defines mechanisms for message transferring between distributed system and remote procedure call/response process. This SOAP is able to be used independently on operating systems and program languages because it uses only a text-based XML for protocol. Therefor ebXML that is a standard for E-Commerce adopts SOAP for message exchange. In this paper, we developed Message Broker System based on SOAP. By this Message Broker System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

SOAP using WSDL(Web Service Definition Language) was proposed for effective integration of distributed objects. But the SOAP message and WSDL document automatically generated from development tool are fully dependent on the development environments. So the dependency of SOAP messages and WSDL documents for objects to the development environment is still a big problem to be solved for the integration of heterogeneous distributed objects. In order to support integration of heterogeneous distributed object, we implemented SOAP Bridge called WBSB(WSDL Based SOAP Bridge). As service request message for a particular service object is translated into appropriate SOAP message for the selected service object by WBSB using WSDL repository, a client can use service object without considering the development environment of the service object.

There are some cases when SOAP message, where WS-Security and WS-Policy elements are included, may consist of a sensitive and important data. In these cases, the message is highly recommended to be secured. The question exists of how to quickly identify that SOAP message satisfies security requirement and security level of a SOAP message. In this paper, we propose a technique called Bit-Stream which depends on the importance of SOAP elements to automatically identify the vulnerabilities and risks while offering advice for higher security.

SOAP is a protocol used for information exchange in distributed computing environment and SOAP defines mechanisms for message transferring between distributed system and remote procedure call/response process. This SOAP is able to be used independently on hardware platforms and operating systems and program languages because it uses only a text-based XML for protocol. Therefore ebXML that is a standard for E-Commerce adopts SOAP for message exchange. In this paper, we implement XML Hub System using SOAP and apply on the system e-Procurement. By this XML Hub System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

When SOAP messages carry vital business information, their integrity and confidentiality needs to be preserved. Concerns have been raised due to XML Rewriting attacks on SOAP message which create a foundation for typical faults in SOAP messages and make it vulnerable to use in Web Service environment. We have already provided a solution to tackle this problem on integrity of SOAP messages in earlier works by proposing a system called System Description Assistant. That system was able to identify and fix typical faults in SOAP messages. This paper mainly reflects future directions of our previous researches and enhances previous ones by adding more comprehensive functions to detect and possibly fix faults occurred due to XML rewriting attacks.

Several Web Service security standards are widely utilized aiming at securing exchanges of SOAP messages among partners in a collaborative environment. Although such standards are suitable for ensuring end-to-end message level security, certain attacks such as XML rewriting may still occur and lead to significant security vulnerabilities. This paper explores the security vulnerabilities of SOAP messages and proposes an ontology-based approach that can successfully combat the security threats. We develop ontology-based schema to include SOAP structure information in outgoing SOAP message and validate this information in the receiving end. Thus, allow to detect XML rewriting attacks early in the validating process.

Recently, the mobile Internet is rapidly changing environment in a user's web server performance requires frequent connection is difficult because the proper response is needed to improve the performance of web services engine. Therefore, the goal of this paper is to improve the performance of web services for the installation of additional access to users regardless of tomcat servlet container and process the request and to shorten processing time of SOAP (Simple Object Access Protocol) message of the server structure to of for web mobile services. The web-sever structure is consists of user demand receiver, web document processor, SOAP protocol processor, NBTM(Non-Blocking and Thread Manager) manager, session manager. The system fully supports a standard web-service protocol, reduces the message processing time and communication overhead of mobile web-service system in Web 2.0 and overhead of server, and confirms the improvement of capability by comparing and evaluating Web 2.0 standard mobile web-service system through delaying achievement evaluation by the experiment of realization in Web 2.0 environment.

Information searched in UDDI transfer web service user. Then web service user require interface to web service publisher. In this paper, we abbreviate procedure it. UDDI require WSDL document to web service publisher. For this reason, UDDI transfer XML form message to publisher. Message include user's location information and UDDI required document transfer from publisher to user. Message using SOAP protocol of XML format.

When SOAP message in Web Services has sensitive and important data, it is necessary to protect the message from XML rewriting attacks. These attacks create a foundation for typical faults in SOAP message and make it vulnerable to use in Web Service environment. Currently, Web Services middleware offers limited functions to detect these faults and possibly fix them. In this paper, we propose a Security Description Assistance which identifies and fixes typical faults in SOAP messages. Our system adapts simulation-based approach, which allows system to self-optimize its performance in different conditions and thus improve the reliability of Web Services.
