The difference between a Bean and a Class:
• Any object that conforms to the rules defined in the specs (here is a local file) can be a bean. Specifically, there is no class all beans must subclass. There is a class: JavaBeans API but note that all of the methods are static so there is really no sense in subclassing. Here is the ( SUN beans page).
• Beans must implement java.io.Serializable
• Beans can have GUI representation or can be "invisible" with no GUI representation. (Both can be visually manipulated in builder tools.)

• Note that there are a lot of links to other files in these; you might want to view them over the web before dowloading so you can see which links you might want to copy as well. Some of the links are just files from your texts, but some are side issues.

• For the Bean lab submission, we have found that downloading .jar files is not handled well on some platforms. However, it seems to work fine if you zip everything (i.e., include your .jar files as one file in a bunch of others) and then when I unzip, I have the .jar file there too. Another alternative is to have the jar file named as a .zip file, and then just tell me to change the name back to .jar
  Another thing that seems to happen is that a jar file mysteriously will not load in the beanbox. Sometimes is says that there is no manifest file. Make sure that your manifest.tmp does not end on the last line of the file, but rather, that you have hit a return

  One more: The icon/image will sometimes not show unless the .jar is placed on the CLASSPATH before starting the BeanBox. This will not affect performance of the JavaBean, just the display in the BeanBox.

  • bean tips using BDK Beanbox. LOOK AT THESE

• SUNS Beans page points to the Bean Builder for the builder tool to download. Since the tool to see the beans is not the issue here, and since I will be demonstrating the older Beanbox, I suggest downloading it from here. The BDK used to be on the CD that you get with Core Java, V2. These days, the java.beans package is in the J2SE download and Core Java authors say that they use NetBeans for the builder environment.
  • JavaBeans Component APIs for Java
  • SUNs (not to be found anymore) How it Works: local version here. And a JavaWorld Beanbox short document on how it works.
  • If you download the BeanBox to your Windows machine do not put the beanbox under "Program Files" or a directory that has a space in it. It may cause problems with connectivity during runtime. (cannot make adaptors)
  • Some have found that images were not found in the beanbox from the jar. It worked when the image was placed in the directory where the beanbox was started. Well, that is annoying!
  • Using version 1.4 or greater changes were made!
  • Local copy of Beanbox examples here (discuss examples that come with the default Beanbox). Source is in your downloaded .zip file.

• Some of the jars in the CoreJava notes/book and in tutorials in case you want to load them and play on a UNIX box

  Technology Comparison to ActiveX/COM

  • JavaBeans is a framework for building applications out of Java components (Beans).
  • ActiveX is a framework for building compound documents with ActiveX controls.
  • A Bean is very similar to an ActiveX control. However, a Bean is written in Java, so has Java's security and cross platform nature.
  • ActiveX controls written in Java is possible, however they require a port of Microsoft's Common Object Model (COM) to be used outside of Microsoft Windows.
  • More frequently, programmers create ActiveX controls in Visual Basic or Visual C++ and compile them into native libraries.

  Recently, JavaWorld contained two articles comparing the technologies. The first article is a strategic analysis of the two. The second article is a head-to-head comparison. JavaWorld has a monthly column on beans.

new DB stuff in the JAVA 1.2 release

• You want to log onto the SUNs (actually, the best machine to use is ect-unix.ecst.csuchico.edu which is the default link to our main server)
  since the Oracle driver is in their /opt/Oracle8i/products/8.1.7/jdbc/lib/classes12.zip directory.

• Setting up with Oracle and trouble shooting , Currently unavailable, use mySQL
  Giving up: Off-site folks can choose to use Windows and an Access database. See setting up and a students example connecting in Java

• testing exceptions

• Some information on the database lab and specifics for Oracle
  • old lab - don't look at this (here for record keeping)

  • Grading this lab perhaps you should readme and about FIREWALLS and some off-site testing problems
  • Note: CASE_SENSITIVITY ALWAYS MATTERS FOR PORTABLE JAVA!!!

• one tutorial, www.sqlcourse.com, SQL Tutorial and another.
  Actually, when I went to google and did a search on SQL tutorial
  I got 149,000 hits. Lots of tutorials on SQL out there!

• You will need the JDBC/ODBC drivers(type I) if you will be talking to a microsoft product(example: Microsoft SQL Server, Access DB). The JDBC-ODBC bridge driver comes packaged with the JDK 1.1 and 1.2

• For some machines, the drivers have to be placed in the same directory as that of the program because the Bridge and Drivers must make native method calls. Many people have the problem of "ClassNotFoundException"
  • For Example : If you are storing all class files under /user/faculty/amk/JDBC/ There is a statement called Class.forName("com.imaginary.sql.msql.MsqlDriver")
    This statement basically loads up the driver, so you have to make sure that the path "com/imaginary/sql/msql/MsqlDriver.class" is under the /user/faculty/amk/JDBC/ directory.

• I repeat: you need to have the JDBC driver installed and you need your CLASSPATH set so that the driver can be found

You should get an account on ECST machines so I can see your servlets run here though. (Test on own machine and put completed lab on ecst machine)

See Marty Hall's notes for TomCat setup (latest tomcat Tutorial by Hall ). I cannot help you with your home setups - if you have problems, just use our machines for testing. Again, to use here: set up your environment
