(i) to determine the brachistochrone, and
(ii) to find a curve such that if any line drawn from a fixed point O cut it in P and Q then OP^n+OQ^n would be constant.
EOImpl.revert() method:
-----------------------
Calling this method will either reset the attribute values to their database
values or revert them to their default values. If the Entity Object is
posted, all the attributes revert to the unread state, so that a subsequent
getAttribute() call will refresh all attributes from the database.
It internally calls
EOImpl.refresh(REFRESH_WITH_DB_FORGET_CHANGES)
1)-Multiple Hanged Windows Explorer Programs
2)-Low virtual memory when the CPU utilization is around 100%.
1)-CTRL+ALT+DEL.
2)-Task Manager
3)-Close all the windows explorer programs.
4)-Click on "Run New Task".
5)-Type "Explorer".
1)-Create a new Application, say ToplinkResearch.
2)-Add a project to this Application, say ToplinkResearch.
3)-Click New->Business Components->select Toplink/JPA.
4)-It will ask for the Database connection and at the same time an offline database
schema it asks for to maintain in the middle-tier.(You can create at the same time
as well!!)
5)-Select the Table name from the List, just we select for an Entity Object.
6)-Thats all and the POJO is created and ready to be compiled.
7)-This class can be refactored to be used in any other project.
8)-Right click on the POJO class and select "New Sample Java Client.." and it will
create a sample Java client that uses this POJO(However, in JM8, this client class
gives runtime exception).

1)-Click on the Java file.
2)-Double Click on any method name.
e.g public void doDML()
select "doDML" word by double clicking the left mouse button.
3)-Select Source->Add Javadoc comments from the menu on top.
1)-Open the required java file in the editor.
2)-Click on "Source" from meny , then "Override Methods".
3)-Select one or multiple methods and it will create the empty body methods with the signatures.
Here is a generic code snippet for calling a PLSQL stored procedure using JDBC.
It takes the stored procedure callablestatement and an array of variables which need to be passed to this procedure.
protected void callStoredProcedure(String stmt, Object[] bindVars) {
PreparedStatement st = null;
try {
st = getConnection().createPreparedStatement("begin " + stmt + "; end;", 0);
if (bindVars != null) {
for (int z = 0; z != bindVars.length-1; z++) {
st.setObject(z + 1, bindVars[z]);
}
}
st.executeUpdate();
} catch (SQLException e) {
throw new SQLException(e);
} finally {
if (st != null) {
try {
st.close();
} catch (SQLException e) {
}
}
}
}
1)-Helps designing and organizing the components(web-tier as well as
the server side bsuiness components) in a much layered manner(Just like BC4J, but more than that)
2)-It uses simple POJOs as the business logic class instead of EJBs.
3)-It has got a greater support for Dependency Injection as each layer of
code in Spring framework works in isolations. So essentially developers
can pull out any layer and test them in isolation.
4)-It has a great JDBC wrapper in it.
5)-It has Inversion of Control container and AOP.(Please google for these two terms)
6)-Most importantly, it provides an env to have a Test Driven Development.

The class com.sun.tools.javac.Main.compile provides the programming interface for javac.
sample code is :int errorCode = com.sun.tools.javac.Main.compile(new String[] {
"-classpath", "bin",
"-d", "/temp/dynacode_classes",
"dynacode/sample/Foo.java" });
errorCode return 0 for Sucess and some non-zero number for any compilation failure.
Also to print the compilation error messages to an o/p file,
it has another overloaded method.// Defined in com.sun.tools.javac.Main
public static int compile(String[] args);
public static int compile(String[] args, PrintWriter out);
