Error "Can't load library: c:\program files\infozoom\izmjniado.dll"

Issue

You may see the error "Can't load library: c:\program files\infozoom\izmjniado.dll" in the exception.log, or in the{servername}-err.log, or in a console window if starting ColdFusion MX from a command line. The error may appear in one of the following forms:

coldfusion.server.ServiceRuntimeException: [JadoZoomOEM]java.lang.UnsatisfiedLinkError: Can't load library: c:\program files\infozoom\izmjniado.dll

could not load izmjniado.dll Can't load library: c:\program files\infozoom\izmjniado.dll

Connection verification failed for data source: {data source name}
com.inzoom.jdbcado.JdbcAdoException: could not load izmjniado.dll Can't load library: c:\program\files\infozoom\izmjniado.dll
The root cause was that: com.inzoom.jdbcado.JdbcAdoException: could not load izmjniado.dll

Reason

In ColdFusion MX 6, this error is more likely to be seen as a licensing error on start up. In ColdFusion MX 7, it is more likely to be seen as a connection error when attempting to connect to a data source using the Microsoft Access with Unicode driver. The error occurs when ColdFusion MX can't find izmjniado.dll because the cf_root/lib directory is not in the library path. It is a misleading error because ColdFusion does not install anything in the \program files\infozoom directory.

Solution

To fix the error, add the cfusion_root\lib directory to the library path in the jvm.config file. In a server configuration, the jvm.config file is located in thecfusion_root/runtime/bin directory. In a multi-server configuration, the jvm.config file is located in thejrun_root/bin directory. If running ColdFusion MX in a J2EE server other than JRun, the library path is set in the JVM configuration file for your J2EE server.

For example, a server configuration may have this set as:

java.library.path={application.home}/../lib

java.library.path=C:/CFusionMX/lib

A multi-server configuration may have this set as:

java.library.path={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib

In ColdFusion MX 7, the library path may also be set with a JVM argument as:

-Dcoldfusion.libPath={application.home}/../lib

Care should be taken not to confuse the java.library.path with the java.class.path.
