Installation Instructions

Installing Library JAR File

JExcel uses JNIWrapper, ComfyJ and WinPack  products,  so  all  these  JAR files should be in the application class path.
Native JNIWrapper library (jniwrap.dll or jniwrap64.dll) is required  for  JExcel  and  it should be placed in the working directory of a Java application.
In the latest JExcel versions the native libraries can also be put into the root directory of any JAR library from the application's classpath.

Installing License File

License  file(s) is  not  the  part  of  this  package  and  should be obtained separately.

To obtain the license, visit  the product's website ( and request evaluation or purchase the product.
The license installation steps depend on the license format:
  • jexcel.lic,  comfyj.lic  and jniwrap.lic or teamdev.licenses have to be put into the same directory as the native code library or in the  META-INF subfolder of any JAR library from the  application's classpath.
  • licence.jar or license.jar are JAR files that already contain the JExcel license in the required location, therefore, there is no need to modify the existing JARs or create a separate one yourself. All you need is to add this JAR to the class path of your application.
Warning: Do NOT rename the license file or it will not be recognized.
