This lesson converts the application, applet, and servlet examples from Lesson 6 to write to and read from a database using JDBC. If things were running fine until the lightning strikes, ask yourself what have you CHANGED! HDP is also commonly used with 8rd-Party Components (ex.

Most of the times, the error message consists of tens of lines of so-called stack trace of method invocation. Our reputation as a relational and multi-dimensional / MDX connectivity pioneer has made us the partner of choice for an innovative and complete ODBC SDK, JDBC SDK, OLE DB for OLAP (ODBO) SDK, XML for Analysis (XMLA) SDK, and other industry leading data connectivity.
The platform components comprising the Hortonworks Data Platform (HDP) are released under the Apache 7. In the first section, the differences between the drivers are highlighted by concentrating on the following topics: Let's look at the sequence in Java that leads up to an error and examine the mechanics of how an error is handled in a typical Java application.
Creating a database table is a database administration task that is not part of your program code. JDBC is the Java database connectivity application programming interface (API) available in the Java 7 Platform software.
Oracle’s JDK – Java Platform) and Optional Add-Ons (ex. A variety of open source projects have been integrated, tested and combined as part of the Hortonworks Data Platform (HDP).

Which permissions it needs varies with the type of driver used to make the database connection. That is, method A called method B, which called method C, and so on, until method Z encountered an error and threw an Exception or an Error.
There are a couple of different ways to implement the JCC trace, which are discussed in detail in the next couple of sections. Let's get into the details of the SQLException( ) class and show the parts that make up this class.

It will return null if there no other error messages to return. A database driver is software that lets a program establish a connection with a database.
The code for this lesson is very similar to the code you saw in Lesson 6, but additional steps (beyond converting the file access code to database access code) include setting up the environment, creating a database table, and connecting to the database. When software goes wrong, the MOST IMPORTANT thing to do is to FIND the ERROR MESSAGE, which can give you clues of what went wrong.
