Java Beans

In 1991, vanilla beans were the highest valued spice import, with shipments totaling 69.0 million, followed by black and white pepper at 60.6 million, capsicum peppers and paprika at 42.6 million, sesame seed at 40.6 million, and cassia and cinnamon at 27.8 million. The most expensive spices, on a unit value basis, include saffron, 1116/kg average New York spot vanilla beans, 80.50/kg for Bourbon beans from Madagascar, Comoros, and Reunion, and 22.05/kg for Java beans and cardamom, 38.54/kg for grade AA bleached Indian and 3.88/kg for Guatemalan mixed greens. 

Among current component technologies, CORBA technology is described at the OMG Web site [CORBA] COM at Microsoft s Web site [COM] and JavaBeans at the Java-Beans Web site [EJB],... 

Controller is the event handler and dispatcher. In J2EE, there are two possible ways of implementing the MVC framework. In Model 1 MVC, Model can be Java Beans, Plain Old Java Object (POJO), or EJB. JavaServer Pages play the roles of View and Controller. Figure 11.1 is a typical Model 1 MVC. 

EJB, etc.) to do the actual work, because the action class is a Web component. It takes HTTP Request as an argument into its execute() method. Coding business logic in the action class makes it less reusable and difficult to test. Action Form is a Java Bean that holds user input from the HTML form. It has the setter methods that Struts uses to set its properties from the HTTP Request object. It also has getter methods that the action class uses to access these properties. Figure 11.3 illustrates a hypothetical compound registration transaction using the Struts framework. 

Phaseolus lunatus beans (lima bean, Java bean) contain the cyanogenetic gluco-side phaseolunatin, which is extremely toxic when hydrolysed. The glucoside is present, but only in small quantities, in cultivated varieties of P. lunatus such as the butter bean. A number of species, including Cicer ensiformis, Dolichus biflorus, D. lablab, P lunatus, P. vulgaris and P. communis, are known to contain lectins, which are toxic...

This article shows how a formerly stand-alone software simulation tool was extended by an internet client and an interface without expensive middleware software. Also the intense cost of large implementation teams can be saved. The software Hybrex WEB presented in this article shows how this can be done by using standards like Java servlets, Java beans and CORBA / RMI. Hybrex WEB was developed by Siemens AG, I S IP PEP in close cooperation with the Technical University of Berlin, Institute for Process Dynamics and Control. 

Yourdon and Coad, 1991). It allows to separate model and view in the web client and simplifies the communication between the different components of Hybrex WEB. The whole object model of a rolling mill is implemented as a standalone Java bean. This bean is used by the web client for parameterization of the plant and to read the calculated values for graphical presentation in tables and diagrams. The simulation request broker uses the same object model and extends it by CORBA functionality. 

The use of one object model for several different applications already proved to be most valuable. Yet the solution as Java bean is restricted to Java applications only. It would be useful to open the simulation service Hybrex WEB to other potential clients as well. XML gained more and more importance during the last years. This W3C (W3C, 2002)-standard is easy to use and serves as the future language for web services. By describing only the contents of the data there can be several different approaches to visualize it. This is equivalent to the separation of model and view discussed earlier. The same data can be converted into other proprietary formats for other tools which will always be found in different industry sections. It is a matter of fact that only the fewest programs... 

The importance of software components for middleware is due to the fact that frequently, components are the basis for middleware implementation. From a historic perspective, the first commercial component models were COM [5] (from Microsoft) and JavaBeans [6]. These models evolved to. NET [7] and newer versions of Enterprise Java Beans (EJB) [8]. Some of the aforementioned middleware even included newer component-based extensions such as the CORBA Component Model (CCM) [9] in the case of CORBA.

Vanilla. Vanilla is the dried, cured, fuU-sized, but not fully ripe fmit pods (beans) of Vanillaplanifolia And. and V. tahitensis J. W. Moore (Orchidaceae). The vine is native to the tropical rain forests of southern Mexico, Central America, the West Indies, and northern South America. Plantings were started in Madagascar, Reunion, Java, Mauritius, and Zanzibar in 1840. The Madagascar-type bean is stUl the most important, but Indonesia produces more than Malagasy. The stmcture of the flower prevents self-pollination and therefore, where insects are not prevalent, hand pollination is necessary. 

In examining vanilla beans the determination of the vanillin is a matter of importance. Busse recommends the following process for the determination 20 grams of the pods, crushed with sand, are exhausted with ether in a Soxhlet tube, and the ethereal extract is shaken out with 20 per cent, sodium bisulphite solution. From the latter, vanillin is removed by treatment with dilute H SO, the SO2 generated removed by a current of CO, and the vanillin extracted by shaking out with ether, evaporating the solvent and weighing the residue. In East African vanilla the author found 2 16 per cent, of vanillin, in that from Ceylon 1 48 per cent., and in Tahiti vanilla from 1-55 to 2 02 per cent. Tiemann and Haarman found in the best Bourbon vanilla 1 94 to 2-90 per cent., in the best Java vanilla 2 75 per cent., and in Mexican vanilla from 1-7 to 1 9 per cent. Tahiti vanilla sometimes contains less than 1 per cent, of vanilla. 

The vanilla bean is the fruit of the orchid Vanilla planifolia, a native of Mexico, but now grown in many tropical countries such as Madagascar, Tahiti, and Java. The flowers of the vanilla orchid are pol-... 

Caffeine was extracted from ficw varieties of roasted coffee beans and was determined in parallel by (1) measurement of spot area after thin layer chromatography on silica gel GF plates (development with chloroform/ cyclohexane/glacial acetic acid, 8 2 1, visualization in UV light), and (2) Kjeldahl N determination. Caffeine contents by (1) and (2), respectively, in the five varieties analyzed were (percent in DM) Santos lave 0, 1.10, and 1.12 Java Robusta 3, 1.19, and 1.22 Camerun Robusta 2, 1.16, and 1.19 Mocca 2, 1.21, and 1.26 Guatemala 0, 1.18, and 1.20.

VANILLIN. Vanillin, [CAS 121-35-5]. CgHgCL, a natural product, can be found as a glucoside (ghicovanillin) in vanilla beans, at concentrations of about 2%. It can be extracted with water, alcohol, or other organic solvents. Approximately 250 by-products have been identified m natural vanilla, out of which 26 are present at levels in excess of 1 ppm. The balance of all these products contributes to the subtle taste of vanilla beans, The vanilla bean contains about 2% vanillin, but the 10% extract prepared from beans has several times lire strength of a solution of 2% vanillin. The best known natural source of vanillin is the vanilla plant, Vanilla planifolia A., which belongs to the orchid family. It is cultivated mainly in Mexico, Madagascar, Reunion, Java, and Tahiti. 

Aroma compounds in cured vanilla beans from different countries, e.g. Madagascar, Tonga, Costa Rica, Java, Indonesia and Mexico, have been documented. Over 100 volatile compounds have been detected, including aromatic carbonyls, aromatic alcohols, aromatic acids, aromatic esters, phenols and phenol ethers, aliphatic alcohols, carbonyls, acids, esters and lactones, of which the aldehyde vanillin is the most abundant. The level of the aldehydes, e.g. vanillin and p-hydroxy-benzaldehyde and their respective acids (vanillic acid and p-hydroxybenzoic acid), in cured vanilla beans is used as an indicator of cured vanilla bean quality for commercial purposes (Klimes and Lamparsky, 1976 Adedeji et al., 1993 Ranadive, 1994). 

Belonging to the same chemical group as atropine is the important alkaloid cocaine, C17H21O4N. It is obtained from the leaves of the coca plant, Erythroxylon coca, which grows in South America (Bolivia and Peru) and in Java and Ceylon. Distinction should be made between the coca plant and the cacao bean from which cocoa and chocolate are made.

Any other (Java-) application can directly use Hybrex for calculation by addressing one function expecting the object model and reading the model with the calculated result values in return. Thus, It only needs to describe a mill using the model bean and trigger a calculation on the server.
