Description

ODF Toolkit uses obsolete distribution of Jena from HP however there is Apache Jena under current development and management.

Replicable steps

The project main method calls following statement.

OdfSpreadsheetDocument osd = OdfSpreadsheetDocument.loadDocument(new File("example.ods"));

The project uses the up-to-date Jena dependency from Apache Jena repository.

<dependency>
    <groupId>org.apache.jena</groupId>
    <artifactId>jena-core</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
     <groupId>org.apache.jena</groupId>
     <artifactId>jena-arq</artifactId>
     <version>3.0.0</version>
</dependency>

Despite that the application fails with

Exception in thread "main" java.lang.NoClassDefFoundError: com/hp/hpl/jena/rdf/model/RDFNode
	at org.odftoolkit.odfdom.pkg.OdfFileDom.initialize(OdfFileDom.java:215)

	at org.odftoolkit.odfdom.pkg.OdfPackage.<init>(OdfPackage.java:250)

	at org.odftoolkit.odfdom.doc.OdfSpreadsheetDocument.loadDocument(OdfSpreadsheetDocument.java:155)

The problem is that OdfFileDom.java uses obsolete HP package name.

Workaround

Following duplicate Jena dependency workarounds the issue:

<dependency>
	<groupId>com.hp.hpl.jena</groupId>
	<artifactId>jena</artifactId>
	<version>2.5.5</version>
</dependency>
