Licensing

Evaluation version of Aspose.Pdf for Java (without a license specified) provides full product functionality, but please Note : At top of all pages in the generated PDF documents are watermarked with "Evaluation Only. Created with Aspose.Pdf. Copyright 2002-200 9 Aspose Pty Ltd" as demos run with an Evaluation License.

The watermark inserted by the evaluation version are shown in the drawing below:

The license is a plain text XML file that contains details such as the product name, number of developers it is licensed to, subscription expiry date and so on. The file is digitally signed, so don’t modify the file. Even inadvertent adding of an extra line break into the file will invalidate it.

You need to set a license before performing any operations with documents. It is only required to set a license once per application (or process).

The lic ense can be loaded from a file or stream. Aspose.Pdf for Java will try to find the license in the following locations:

1. Explicit path.
2. The fol der that contains Aspose.Pdf.jar .

The easiest way to set a license is to put the license file in the same folder as Aspose.Pdf. jar and specify just the file name without path as shown in the following example:

// create license object    
com.aspose.pdf.License lic = new com.aspose.pdf.License();
try {
     // load the license file and instantiate it with Aspose.Pdf for Java object
     lic.setLicense(new FileInputStream(new File("Aspose.Custom.Java.lic")));
       	} catch (Exception e) 
		{
       		System.out.println(e.getMessage());
		}
 

The following example shows how to load a license from a stream:

// create license object
com.aspose.pdf.License license = new com.aspose.pdf.License();
// load the license file into FileStream object
FileInputStream myStream = new FileInputStream("Aspose.Pdf.Java.lic");
// initialize Aspose.Pdf for Java license
license.setLicense(myStream);
