can't access font resource

2004-02-19 18:26



I had a project with a font "kaiu.ttf" build on tomcat. My project will produce an output stream to start Acrobat reader just like that in the "webapp" sample. Sometimes my project works and somtimes the following message pop up

. If I access the project at the first time after the Tomcat startup , there's nothing wrong. If I access that not in the first time, there's a large probability to encounter the exception. Who could help me?


ExceptionConverter: java.lang.NullPointerException
