Deploying your Applications on WebSphere Application Server 7.0 (Part 1)

by Steve Robinson | August 2009 | Java

After installing an application server, we would want to deploy applications. Applications can be installed manually or in an automated fashion using scripts. In this two-part article by Steven Charles Robinson, we will cover how to manually deploy a J2EE (Enterprise Edition) application. As we walk through this article, we will show you how to deploy two applications. One application does not require database connectivity; the second is a database aware application which requires some WebSphere configuration to provide database connectivity to the application.

In this article, we will cover the following topics:

  • Application server internals
  • The web container
  • Virtual hosts
  • WebSphere ports
  • Data sources
  • Java Naming and Directory Interface (JNDI)
  • Application deployment
  • J2EE applications
  • Enterprise Archive (EAR)
  • Web Archive (WAR)
  • Java Archive (JAR)

Dependency Management in SBT

by Shiti Saxena | October 2013 | Open Source Web Development

Software development never happens in isolation. Most of the time, for complex projects, you will not work alone, nor will you develop all the components in the product from scratch. Products are generally created in teams, and they generally rely on external libraries and components. A product itself can be broken into modules developed by different teams dependent on each other. Dependencies in software development refer to the libraries or components required at various stages (compile, test, and runtime) of an application's development life cycle. The process of handling these dependencies, external or internal, for your application is called dependency management. In this article by Shiti Saxena, author of Getting Started with SBT for Scala, we will venture into dependency management.

On the surface, it looks simple. All you have to do is take the JAR file and add it to your project. But when you actually have to handle it, problems arise. Some of the challenges are as follows:

  • Version management: This will track the version of various dependencies you are using. Download the latest ones when they become available and replace the old ones. Ensure someone else in the team doesn't simply change the JAR file to a newer/older version.
  • Transitive dependencies: This handles the chain of dependencies of the libraries you are dependent on, and also the dependencies of these dependencies.
  • Releasing your library: If your library is part of a larger project, making your library available to others to use in an easy way is a challenge, especially when it is updated frequently (think about nightly snapshots).

Defining the Application's Policy File

by Pragati Ogal Rai | August 2013 | Open Source

This article created by Pragati Ogal Rai, the author of Android Application Security Essentials, will use the application components, Intents, and permissions and put them all together to define our application's policy file. This policy file is called AndroidManifest.xml and is by far the most important file of an application. As you will see, this file is the place to define access control policy for your application and components. This is also the place to define application and component level specifics that the Android system will use to interact with your application.

The article begins with a discussion of AndroidManfiest.xml. We will discuss the two important tags: <manifest> and <application> that we have not discussed so far. Next, we will discuss the actions that we can perform in the manifest file such as declaring permission, sharing a process with other applications, external storage, and managing component visibility. The article closes with a discussion of a checklist for your policy file before you release your application. You should adapt the checklist according to your use case. Once you have a comprehensive checklist, you can refer to it every time you are ready to make a new release.

Defining a Data Model for Spatial Data Storage

by Simon Greener Siva Ravada | October 2013 | Enterprise Articles Oracle

In this article by Simon Greener and Siva Ravada, the authors of Applying and Extending Oracle Spatial, we provide a SQL schema and functions that facilitate the storage, update, and query of collections of spatial features in an Oracle database.

Oracle Spatial and Graph provides a SQL schema and functions that facilitate the storage, update, and query of collections of spatial features in an Oracle database. Oracle Spatial and Graph is the new name for the feature formerly known as Oracle Spatial. In this article, we refer to this feature as Oracle Spatial for the sake of simplicity. We also focus exclusively on spatial feature of Oracle Spatial and Graph in this article. Oracle Spatial mainly consists of the following:

  • A schema (MDSYS derived from Multi-Dimensional System) that defines the storage, syntax, and semantics of the supported geometric (both vector and raster) data types
  • A spatial indexing mechanism for faster querying and retrieval
  • Operators, functions, and procedures for performing spatial analysis and query operations
  • A persistent topology data model for working with data about nodes, edges, and faces in a topology
  • A network data model for modeling and working with spatial networks
  • A GeoRaster data type and associated functions that let you store, index, query, analyze, and deliver raster data

Debugging PL/SQL in Oracle SQL Developer 2.1

by Sue Harper | September 2010 | Enterprise Articles Oracle

Once your PL/SQL code has successfully compiled, it is important to review it to make sure it does what is required and that it performs well. You can consider a number of approaches when tuning and testing code. These approaches include:

  • Debugging—run the code and add break points to stop and inspect areas of concern.
  • SQL performance—use Explain Plan results to review the performance.
  • PL/SQL performance—use the PL/SQL Hierarchical Profiler to identify bottlenecks.
  • Unit testing—review edge cases and general function testing. Does the code do what you intended it to do?

In this article by Sue Harper, author of Oracle SQL Developer 2.1, we'll review the debugger. We will see how to debug PL/SQL packages, procedures, and functions.
