The inner class GetData is called, which in turn calls a JSP script named sql_xml.jsp. This JSP reads the database, where items and their quantities are stored, and returns the item code, quantity available, and the unit price of the item in XML format. The XML data is parsed in the parseData method of the GetData class by using a third-party XML parser. It is simultaneously stored in vectors. After the data has been completely parsed, the values of the items stored (quantity and price) are returned. At this point, the list of items is displayed, showing quantity and item codes in Figure 7-5.

2 kbyte versus mean in GPRS 21 kbyte) see Figure 144 (a2) than GPRS users This can also be seen in the ecdf of the object sizes in one page, Figure 144 (b2) Secondly, the download time of the UMTS HTTP pages is the same as for the GPRS pages This point is important because it could indicate a hard limit on the user side, for example a maximum tolerance time a user will wait for a page The Radio Access Network (RAN) in UMTS is approximately three times faster than in GPRS; this manifests itself in a measured difference of the mean HTTP page size Figure 144(a) shows the number of objects per page as an ecdf It is interesting to see that there are over 50% of requests resulting in a page with only one object In the literature (Reyes et al.

Web services and the bene ts that they can bring us It is clear that Web services are the path ahead as they provide a simple and open standards-based middleware for distributed computing OGSA uses a range of Web services technologies to provide an infrastructure that is appropriate for Grid applications Since in the distributed world of the Grid the same problems arise as on the Internet, concerning the description and discovery of services, OGSA certainly takes an approach to embrace these technologies OGSA is the de facto standard for building service-oriented Grid services and applications OGSA introduces a couple of new interfaces (portTypes) to meet the Grid needs in the context of WSDL While Web services are persistent and stateless, Grid services can be transient and stateful To meet this end, OGSA introduces the concept of GSH/GSR and service data element associated with each Grid service.

otal Points and other recurring patterns. It was obvious to Livermore that as the volume drastically changed in a stock, it was a clear aberration or deviation from the normal behavior of the stock. But was the volume accumulation or was it distribution Livermore was an expert at detecting distribution. He had formed a strong opinion on that subject, because he knew how stocks were distributed by the pool runners of his day. The pool runners, experts like Livermore, were often charged with distributing the stock of the insiders who had formed a pool with their own stock for the purpose of controled distribution. How did the pool runners do it The same way as they do it today. Stocks were never distributed on the way up . . . they were distributed on the way down. The reasoning was simple people will not take their losses when they should. The public will hold on to their stock as it drops and wait until it rallies back to the price where they bought it, so they can
