The ArcSDE Java API provides an open, high level Programmer's Interface to process and analyze spatial information.
The Java API mirrors functionality provided by the ArcSDE C API.
The Java API contains three packages:
- com.esri.sde.sdk.client provides classes that expose ESRI's ArcSDE server functionality. Applications created with this package can establish a connection to an ArcSDE instance, query a layer, and otherwise communicate with an ArcSDE server.
- com.esri.sde.sdk.geom contains classes that implement the OGC (Open
GIS Consortium) Geometry interfaces.
- com.esri.sde.sdk.pe provides classes to define coordinate systems and to transform data between different coordinate
systems.
Setting up the Java API
During ArcSDE 9.2 client install, the following files are installed:
| jsde92_sdk.jar |
Contains the ArcSDE Client, and Geometry
Java API class files. |
| jpe92_sdk.jar |
Contains the ArcSDE Projection Engine Java
API class files. |
| concurrent.jar |
Provides standardized,
efficient versions of utility classes commonly encountered in concurrent Java
programming. |
| icu4j_3_2.jar |
ICU4J libraries required for
globalization. |
To build applications with the ArcSDE Java API, users must have Java 2
Standard Edition SDK, version 1.4.0 or higher installed on your system. You must
also add the jsde92_sdk.jar, jpe92_sdk.jar, concurrent.jar, and icu4j_3_2.jar
files to your CLASSPATH.
Setting up the Java API for Direct Connect Using JNI Implementation
In ArcSDE 9.2, Direct Connect is supported through a JNI implementation. In
order for Direct Connect to work additional files are required and the
environment variables need to be set accordingly. In this release, the Java API
Direct Connect is only supported in the Windows, Solaris and Linux platforms.
Set the library path to include the SDEHOME/lib.
The following libraries are required for Direct Connect support.
| libsdejavautil |
This modules contains the ArcSDE direct
connect library functions. |
| libgsrvr*92 |
This modules contains the ArcSDE direct
connect library functions. |
| libsde*gsrvr92 |
This modules contains the ArcSDE direct
connect library functions. |
| libsde* |
This modules contains the ArcSDE client
library functions. |
| libsg* |
This modules contains the ArcSDE shape
library functions. |
| libpe* |
This modules contains the ArcSDE PE
library functions. |
| libxerces* |
This modules contains the XML parser
library functions. |
| libicu* |
This modules contains the Unicode
support library functions. |
Set the SDEHOME environment variable to the ArcSDE home directory, and include
the %SDEHOME%/bin in the PATH environment variable.
The following DLLs are required for Direct Connect support.
| sdejavautil.dll |
This modules contains the ArcSDE direct
connect library functions. |
| gsrvr*92.dll |
This modules contains the ArcSDE direct
connect library functions. |

connect library functions. |
| sde.dll |
This modules contains the ArcSDE client
library functions. |
| sg.dll |
This modules contains the ArcSDE shape
library functions. |
| pe.dll |
This modules contains the ArcSDE pe
library functions. |
| xerces*.dll |
This modules contains the XML parser
library functions. |
| icu*.dll |
This modules contains the Unicode
support library functions. |
