    • My answer to question one.
      All the packages beginning with javax are called Java standard extensions. For instance, javax.swing.*, javax.servlet.*, javax.servlet.jsp.*, javax.ejb.*, javax.naming.*. Take me as an example, I am proficient in using Servlet, JSP, EJB, JNDI, Swing, JavaMail APIs.
    • My guess work regarding question two.
      I could not understand that question well. If one simply wants to extract some patterns from a text file, I guess PERL is a good candidate. Of course, one can use Java. I don't have PERL experiences. But I can do the job by using java.text.* package.
    • My guess work about question three.
      Since we are executing Java classes, my big concern is multi-threading issue. On the Windows machine, Java virtual machine can use native threads. If we work on Sun Solaris, we need to keep in mind that JVM (at least before JDK 1.3) use so-called green threads.
