My new workstation has a 4K screen. Although the OS scales nicely, Java applications that do not run under Java 9 or higher do not. This leaves me with a very tiny JProfiler UI. As Java 9 is EOL'd. Final support for Java 9. While we have tracked the evolving state of the new module system in Java 9 over the past JProfiler releases, the final feature set of Java 9 is now expected to remain stable. JProfiler 10 fully supports the latest builds of Java 9 and is expected to support the final release as well.
This topic shows you how to create a console based Java ArcObjects application. It also provides instructions for compiling and running ArcGIS Engine applications using the ArcObjects application programming interface (API) without an integrated development environment (IDE).
In this topic
- Output of the program
Console based HelloWorld application
The following code example is for an ArcObjects application that prints the active data frame in a map document (.mxd file) to the console window:
[Java]Analyzing the program
- Initialize the Java COM Interop—It is essential to initialize ArcObjects Java applications to set up the communication between the native COM ArcObjects components and corresponding Java classes through the Java COM Interop, which the EngineInitializer class performs.
- Initialize a valid License—The initialize() method of the AoInitialize object establishes permissions to access appropriate ArcObjects through licensing and checking out extensions. ArcObjects based applications can run against the ArcGIS Engine Runtime license or if available and coded appropriately, an ArcGIS Desktop license, such as Basic, Standard, or Advanced. For more licensing information, see Licensing and deployments.
- Invoke ArcObjects—A simple ArcObject, MapServer (com.esri.arcgis.carto) is created. The MapServer ArcObject provides programmatic access to the contents of a map document (.mxd file) on disk and creates images of the map contents based on user requests.
- In this example, the connect method of the MapServer class is invoked to initialize the map server with a map document (.mxd file) stored at the specified path. Another simple method, getDefaultMapName, is invoked on the MapServer ArcObject that returns the active map name (i.e. the name of the active data frame).
- Release the license—It is good programming practice to release the license. The shutdown method of the AoInitialize releases resources and informs ArcObjects that its services are no longer needed. Also, AoInitialize is a singleton class; therefore, do not worry that you're shutting down a different system than the one you initialized earlier. However, as shown in the code segment above, save a reference to the first AoInitialize object and use it to invoke the shutdown method.
In the example program, the caught exception is an IOException. Nearly all ArcObjects exceptions thrown in Java are an IOException or AutomationException, which is a subclass of IOException.
Compiling and running the application
The ArcObjects Java application can be compiled and run like any other Java application. The following initial steps are required to successfully compile and run any ArcObjects Java application:
- The Java compiler needs to be aware of the location of the referenced ArcObjects classes. The ArcGIS Engine Runtime as well as ArcGIS Desktop contains all the ArcObjects classes packaged into a set of Java Archive (JAR) files (arcobjects.jar). Depending on the product you have installed on your machine, this .jar file is typically located in either the <AGSDESKTOPJAVA>javalib or <AGSENGINEJAVA>javalib folder or potentially both if you have both products installed. You need to include this .jar file in your classpath when compiling the ArcObjects Java application. Assuming you have ArcGIS Engine Runtime and a supported JDK installed, to compile the ArcObjects application, run the following command:
- javac EngineHelloWorld.java -cp '%AGSENGINEJAVA%javalibarcobjects.jar'
- On UNIX platforms, source the init_devkit script (.sh or .csh, located in your <DevKitInstallDir>) to automatically setup the necessary environment variables and execute:
- javac EngineHelloWorld.java -cp '$AGSENGINEJAVAjavalibarcobjects.jar'
- The same applies to the Java interpreter (i.e. Java Runtime Environment or JRE):
- java -cp '%AGSENGINEJAVA%javalibarcobjects.jar;.' EngineHelloWorld
- On Unix platforms, run the following command at your command line or shell:
- java -cp '$AGSENGINEJAVAjavalibarcobjects.jar:.' EngineHelloWorld
Output of the program
Finally, if you see the Hello, ArcObjects!: Geography output when running the ArcObjects application from your console, you have created your first non-visual ArcObjects application. Geography is the active data frame for the brazil.mxd map document.

EJ Technologies JProfiler 10.1.5 (x86/x64) + macOS | 77/77/137 Mb
JProfiler is a powerful tool that you can use to profile Java based applications in a dynamic way and enables you to analyze them in hopes of optimizing performance.

EXCEPTIONAL EASE OF USE
When you profile, you need the most powerful tool you can get. At the same time, you do not want to spend time learning how to use the tool. JProfiler is just that: simple and powerful at the same time. Configuring sessions is straight-forward, third party integrations make getting started a breeze and profiling data is presented in a natural way. On all levels, JProfiler has been carefully designed to help you get started with solving your problems.

DATABASE PROFILING FOR JDBC, JPA AND NOSQL
Database calls are the top reasons for performance problems in business applications. JProfiler's JDBC and JPA/Hibernate probes as well as the NoSQL probes for MongoDB, Cassandra and HBase show the reasons for slow database access and how slow statements are called by your code. From the JDBC timeline view that shows you all JDBC connections with their activities, through the hot spots view that shows you slow statements to various telemetry views and a list of single events, the database probes are an essential tool for getting insight into your database layer.

EXCELLENT SUPPORT FOR JAVA ENTERPRISE EDITION
Dedicated support for JEE is present in most views in JProfiler. For example, in the JEE aggregation level you see the call tree in terms of the JEE components in your application. In addition, the call tree is split up for each request URI. Also, JProfiler adds a semantic layer on top of the low-level profiling data, like JDBC, JPA/Hibernate, JMS and JNDI calls that are presented in the CPU profiling views. With its JEE support, JProfiler bridges the gap between a code profiler and a high-level JEE monitoring tool.

HIGHER LEVEL PROFILING DATA
JProfiler has a number of probes that show you higher level data from interesting subsystems in the JRE. In addition to the Java EE subsystems like JDBC, JPA/Hibernate, JSP/Servlets, JMS, web services and JNDI, JProfiler also presents high level information about RMI calls, files, sockets and processes. Each of these probes has its own set of useful views that gives you general insight, highlights performance problems and allows you to trace single events. And what's more, all these views are also available for your own custom probes that you can configure on the fly within JProfiler.
