Media Galleries come to the Resource Centers

We are proud to announce that we have recently updated the Resource Centers to include Media Galleries!  The main resource you will find in the galleries are videos, but you might also find Power Point Presentations and code files that are associated with certain entries.

  Media Galleries

These videos are classified into three categories :

  • Presentations: Recordings from various conferences and public events
  • How to: Get a tour through various code gallery entries or learn how to accomplish specific programming tasks
  • ESRItv: get a behind the scenes look at our software straight from the development teams

So far, the following community areas have galleries:

ArcGIS API for JavaScript
ArcGIS JavaScript Ext. for the Google Maps
ArcGIS JavaScript Ext. for Microsoft Virtual Earth
ArcGIS API for Flex
.Net ADF
Java ADF
ArcGIS Mobile
ArcGIS Desktop
Model and Script
ArcGIS .Net Engine
ArcGIS Java Engine

What’s new for Java Developers in 9.3.1?

As a Java developer have you ever wanted to extend your desktop and server applications natively using the Java API?  If so, you’ll be happy to know that the ArcGIS 9.3.1 release allows you to extend the ArcGIS framework by creating Java extensions that plug seamlessly into ArcObjects components. This is a big improvement because to accomplish this before Java developers were required to develop functionality in a COM compliant language then use the proxygen tool to create the Java wrappers. Say good bye to those days!

Red Hat

The ArcGIS 9.3.1 release
provides enhanced support for Java developers to develop extensions in the native Java environment using a simple develop and deploy workflow. Some of the supported extensions include:

  • Custom geoprocessing tools
  • Server object extensions (SOEs) and utility objects
  • Class extensions for customized data behavior
  • Custom renderers
  • Plug-in data sources

Also, the development team will be presenting in-depth sessions on developing and deploying ArcGIS Java Extensions at our upcoming Developer Summit in Palm Springs, CA. These sessions include ‘Extending ArcGIS with Java’ and ‘Extending ArcGIS Server with Java’.  You can also listen to our podcast ‘2009 ESRI Developer Summit: Extending ArcGIS with Java’ for more information.

Accessing ArcGIS Java Help System Content From within Eclipse Developer IDE for Windows Developers

The Help System in the Eclipse Developer IDE is designed like the rest of the environment and is built with a plug-in architecture.  Packaging the Java Help System as a Developer IDE Plug-in can significantly increase memory size requirements and cause the development environment to hang on install.  This article discusses taking advantage of the Java Help System InfoCenter as a stand-alone Help System to be integrated into your Eclipse Developer Environment. This can be done in 3 easy steps.

Step 1: To get started, you must first ensure that you have installed the ArcGIS SDK Java Help System.  This is a separate installer from ArcGIS Engine and/or ArcGIS Server for Java.  Once successfully installed, the help system runs in single user mode as stand-alone help system for the Java developers.  To set up the Java Help System in InfoCenter mode you simply execute the Java Help Server scripts located at ‘%ARCGISHOME%java docs’.  To start the Help System in InfoCenter mode, execute the ‘startJavaHelpServer.bat’ file:

%ARCGISHOME%javadocsstartJavaHelpServer.bat [<port>]

The default port the Java Help System InfoCenter will run on if you do not set the port when you execute the script will be ‘2112’.  Clients can now access the Java Help System from any machine inside your network by pointing your web browser to the following url:  


Step 2: Now that you have successfully started the Java Help System in InfoCenter mode, you can easily integrate the Help System into your Eclipse Developer IDE. 

Make sure you have the latest supported Eclipse developer IDE, version 3.3.x, and open the Preferences dialog by selecting ‘Window->Preferences’ from the tools menu.  In the Preference dialog, navigate to ‘Help->Content’ as shown in an illustration to the right. 

Step 3: The Eclipse Help System needs to know the address (host/IP) and port of the remote server to integrate with the local system. Select the ‘Include help content form a remote infocenter‘ checkbox and provide the following server information: 

  1.  Host: Put a valid Server Name or IP Address where the remote infocenter is located. In our example the server name is ‘javabuild’.
  2. Path: ‘/help’.
  3. Select the ‘Use Port’ radio box and put ’2112′ in the port text box. The dialog should resemble the image below with your server name replacing ‘javabuild’.

Click ‘OK’ to close the Preference dialog and open up the Eclipse Help System, ‘Help->Help Contents’, to see the ArcGIS Java Developer Help System integrated into your local Eclipse Help System. 

The Java Help System InfoCenter is a stand-alone server and doesn’t require an additional Web Server.  However, in a production environment, you may want to control important issues that are best handled by a Web Server.  For example, you may want to redirect requests by setting up a proxy module in Apache.  This is all possible for more advanced users of the java Help System InfoCenter.

ArcGIS Developer Poll: Java IDEs

Well, you may not need us to state the obvious, but an overwhelming percentage of you chose Eclipse for your Java development (over 53%). Netbeans was a distant second with 25%. This could be because they’re both open source and free or it could be due to the fact that we’ve targeted these IDEs with our Engine and Server plug-ins? The popularity of Eclipse and Netbeans may not be surprising but anyone care to comment on why they use one instead of the other?

It was surprising to see JBuilder with such a low percentage (4%). Granted, we had a small sample population that took the survey, but maybe this is due to its price tag?

And lastly, in case you’re wondering, the single “Other answer …” was VI!
