To render Word 2007, Excel 2007 and PowerPoint 2007 documents, VirtualViewer HTML5 for Java may rely on third party packages. In order to properly integrate these packages, the CLASSPATH may have to be modified.

You can specify additions to the CLASSPATH using the web.xml parameter classPathAddition according to the following example:

<init-param>
<param-name>classPathAddition</param-name>
<param-value>c:\sample\sample-cells-7.4.3.jar;c:\sample\dom4j-1.6.1.- jar;c:\sample\sample.slides-7.3.0.jar;c:\sample\log4j-1.2.16.jar;
</param-value>
</init-param>
