Even though there is an init method in a servlet which gets called to initialise it, a constructor is still required to instantiate the servlet. Even...

Author: Alex Chaffee (http://www.jguru.com/guru/viewbio.jsp?EID=3) Question originally posed by Ian Phillips (http://www.jguru.com/guru/viewbio.jsp?EID=38182 It depends on the servlet engine. Each has its own type of config file in which you can set the names and values of init parameters; these get passed to the servlets (or JSPs) via the getInitParameter() call. Resin: Look for the resin.conf file in your Resin1.1/conf directory. See similar questions...

Depends. They may go on strike when provoked. Luckily, if your program involves air traffic control, the ISO standard guarantees that Ronald Reagan will fire any unions that go on strike, and replace them with structs, which should be close enough. [a] See similar questions...

Some people feel you should not use the this pointer in a constructor because the object is not fully formed yet. However you can use this in the constructor (in the {body} and even in the initialization list) if you are careful. Here is something that always works: the {body} of a constructor (or a function called from the constructor) can reliably access the data members declared in a base class and/or the data members declared in the constructor's own class.

In object-oriented programming, an object's constructor is responsible for initializing the object completely at creation time. The constructor receives the list of options passed to the snit::type command's create method and can then do whatever it likes. That might include computing instance variable values, reading data from files, creating other objects, updating type and instance variables, and so forth. See similar questions...

The Polynomial(int d, double *coefs) constructor is invoked when an object of type Polynomial is defined using the appropriate arguments. For example, double co[] = { 1.2, 3.4, 5.6 }; Polynomial p(2, co); constructs p to represent 5.6x2 + 3.4 x + 1.2. See similar questions...

Chlorine changes the tastes and odor of water. Chlorination can also produce harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer. No, the UV unit will use about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality where microbiological contamination is present and to provide peace of mind where microbiological contamination is a greater risk.

The mohel is a super-specialist, an expert at his profession, who probably possesses more experience at performing circumcisions than most doctors. A mohel may have the opportunity to perform more brisses in a month than some doctors do in an entire year. Doctors may be called away on medical emergencies and have to cancel their participation in your child's circumcision at the last minute. See similar questions...

When we started developing MusicXML, a DTD (Document Type Definition) was the only official W3C recommendation for defining an XML document. Since that time, XML Schemas have become an official W3C recommendation, and alternative schema languages like RELAX NG have also become available. W3C XML Schemas offer many benefits when using XML in electronic commerce and business database applications. For musical documents, though, the advantages are less compelling.

This is mainly a stylistic decision. Several XML books advise representing semantics in elements rather than attributes where possible. One advantage of doing this is that elements have structure, but attributes do not. If you find that what you are representing really has more than one part, you can create a hierarchical structure with an element. With attributes, you are limited to an unordered list.

Answer: A JSP engine preserves white space, such as carriage returns in a JSP file, when it translates the JSP into a servlet. Thus, when a non-ASCII document format, e.g. Microsoft Word, is streamed from the K2 Viewing service to the browser, the added white space may prevent the browser from properly rendering the document.

A servlet is a program written in the Java programming language that runs on the server, as opposed to the browser (applets). Detailed information can be found at http://java.sun.com/products/servlet. See similar questions...

Let us assume the DataSource name is OracleDS and the location is jdbc/OracleDS. These are defined in the j2ee/home/config/data-sources.xml file. The following code demonstrates how to lookup the DataSource and obtain a connection. try { InitialContext context = new InitialContext(); DataSource myDS = (DataSource) context.lookup("jdbc/OracleDS"); Connection conn = myDS.getConnection(); ... // Use connection as normal since it's a normal JDBC connection } catch(NamingException ne) { ..

Maybe, but be careful. ReaderWriterLock is used to allow multiple threads to read from a data source, while still granting exclusive access to a single writer thread. This makes sense for data access that is mostly read-only, but there are some caveats. First, ReaderWriterLock is relatively poor performing compared to Monitor.Enter/Exit, which offsets some of the benefits. Second, you need to be very sure that the data structures you are accessing fully support multithreaded read access. See similar questions...

Whilst both fabrics are natural products, silk has the advantage over cotton as it is a protein fibre of animal origin rather than a vegetable fibre and has the ability to mimic human hair. The long strands of silk provide a smooth, friction free garment which will not irritate the skin, even on the most active toddler. In addition, DermaSilk is capable of maintaining a stable body temperature in whatever climate and absorbing up to 1/3 rd of its weight in moisture before it begins to feel damp.
