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 client installation, the following files are installed:
| jsde_sdk.jar |
Contains the ArcSDE Client, and Geometry
Java API class files. |
| jpe_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 Development Kit version
6 or higher installed on your system. You must
also add the jsde_sdk.jar, jpe_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 and higher, direct connect is supported through a JNI
implementation. For a direct connection 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. Also set the LD_LIBRARY_PATH
environment variable for all operating systems except IBM and HP. Set SHLIB_PATH
for HP operating systems and LIBPATH for IBM operating systems. If using an
Oracle DBMS, also set ORACLE_HOME.
The following libraries are required for direct connect support.
| libsdejavautil |
This modules contains the ArcSDE direct
connect library functions. |
| libgsrvr*93 |
This modules contains the ArcSDE direct
connect library functions. |
| libsde*gsrvr93 |
This modules contains the ArcSDE direct
connect library functions. |
| libsde* |
This modules contains the ArcSDE client
library functions. |
| libsg* |

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.
Also set the ORACLE_HOME environment variable. The following DLLs are required for direct connect support.
| sdejavautil.dll |
This modules contains the ArcSDE direct
connect library functions. |
| gsrvr*93.dll |
This modules contains the ArcSDE direct
connect library functions. |

library functions. |
| icu*.dll |
