Error: java.lang.UnsatisfiedLinkError: no ntvinv in java.library.path
Error Message
When compiling or executing a Java application that uses the ArcObjects Java API, the following error is returned:
java.lang.UnsatisfiedLinkError: no ntvinv in java.library.path
Cause
The PATH variable does not include a directory which contains the native libraries required for ArcObjects Java classes to function.
Solution or Workaround
Add the directory that contains the native libraries needed by ArcObjects Java to the PATH variable.
- On both Windows and Unix platforms, add either of the following directories to the PATH variable:
A. $AGSDESKTOPJAVA\java\jre\bin
B. $AGSDESKTOPJAVA\binNote:
$ARCENGINEHOME may need to be replaced with the location of the ArcGIS SDK installation. - Unix also provides the option of running the ArcEngine helper scripts in $ARCENGINEHOME: init_engine.csh or init_engine.sh.
- See ArcGIS SDK for Java Environment Settings in the Related Information section below for additional information.
On Windows, you must modify your PATH
system variable to include either:
%AGSDESKTOPJAVA%\java\jre\bin
%AGSDESKTOPJAVA%\bin
