NoClassDefFoundError javax/xml/bind/DatatypeConverter

GroupDocs.Viewer for Java API depends on javax.xml.bind for working with PDF files, that is; in case of using Java 9 and above and if the program is required to work with PDF file types, it is required to add reference of javax.xml.bind in the project’s class path, because the library was removed from standard Java library.


You may get exception like java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter.


The solution is actually very simple as detailed below.

  • Download jaxb-api-2.3.0.jar library as JAR file from Maven repository.
  • Put the file into your project directory.
  • Reference the jaxb-api-2.3.0.jar in the class path of the project.

Alternatively, you can add the dependency in the pom.xml and let the project resolve the dependency via maven.
