Explanation
I am trying to run the following sample program to try out Tess4J, but I am getting Unable to load library 'tessdll': exception. I have checked tessdll.dll is in my path. I am using 64-bit Windows7. Please help in resolving this issue.
Thejava.lang.Runtime.loadLibrary(String filename)method a good deal the dynamic library with the selected library title. A document containing native code can be packed from the nearby file program from a place where library files are usually conventionally obtained. The information of this procedure are usually implementation-dependent. The mapping from a library name to a specific filename is usually done in a system-specific way.
Very first, if there is certainly a protection supervisor, its checkLink technique is known as with the libname as its disagreement. This may result in a security exception. The method System.loadLibrary(Line) is certainly the standard and practical means of invoking this technique. If indigenous methods are to end up being utilized in the implementation of a course, a regular strategy can be to place the indigenous program code in a library document (contact it LibFile) and after that to put a static initializer −
within the course assertion. When the class is packed and initialized, the necessary native program code execution for the native strategies will after that be packed as properly. If this technique is known as even more than as soon as with the same library name, the 2nd and subsequent calls are ignored.
Assertion
Using is the statement forjava.lang.Runtime.loadLibrarymethod
Variables
libname− the name of the library.
Come back Value
This technique does not come back a value.
Exception
- SecurityException− if a protection manager exists and its checkLink method doesn'capital t allow loading of the specific dynamic library
- UnsatisfiedLinkError− if the library will not exist
- NullPointerException− if libname is usually null
Example
The following example shows the use of lang.Runtime.loadLibrary technique.
Live life DemonstrationLet us put together and run the above program, this will create the subsequent result −
