Steps to deploy the dtSearch Engine in a 64-bit Java application (Windows).
1. Copy dtSearchEngine.jar (from <dtSearch>\examples\java\classes) to a folder that is on the Java CLASSPATH. This file is the same for 32-bit and 64-bit versions.
2. Copy dtsjava.dll and dtengine64.dll (from <dtSearch>\bin64) to a folder that is on the system PATH.
Java version or later 1.4.1 is required.
For additional optional files and components, please see: Installing the dtSearch Engine.
Under 64-bit Windows, the dtSearch Java API requires dtsjava.dll, which in turn uses the dtSearch Engine DLL, dtengine64.dll. These two DLLs are installed in the dtSearch Engine bin64 folder. Both must be located in a folder that is listed in the PATH environment variable so the Java run-time can find them.
Both the 32-bit and the 64-bit dtsjava.dll have the same name. The version you use must match the Java version you are using, so under 64-bit Java you should use the 64-bit version of dtsjava.dll. To ensure that the correct version is used with the Java version you have, set the system PATH so the correct dtSearch folder (bin64 or bin) comes first. For example, to use the 64-bit version, set up your system path with C:\Program Files\dtSearch Developer\bin64 ahead of C:\Program Files\dtSearch Developer\bin.
