PDF in Cocoon 2.1.12 Tomcat

Hi,

I have an 2.1.12 application which produces some PDF pages.

It works well on my windows machine, however, on my debian tomcat server the pdf pages produce the 
following error


*type*Exception report

*message*_Servlet execution threw an exception_

*description*_The server encountered an internal error (Servlet execution threw an exception) that 
prevented it from fulfilling this request._

*exception*

javax.servlet.ServletException: Servlet execution threw an exception

*root cause*

java.lang.Error: Probable fatal error:No fonts found.
	sun.font.FontManager.getDefaultPhysicalFont(FontManager.java:1087)

	sun.font.CompositeFont.getMapper(CompositeFont.java:390)
	sun.font.CompositeFont.canDisplay(CompositeFont.java:416)


Any Ideas Please
