Thanks Steven Blough By: Steven Blough - stevenblough RE: problem running on i-planet 2002-02-19 10:23I forgot to mention that it works fine in tomcat 4 on windows 2000 Thanks Steven Blough By: Teodor Danciu - teodord RE: problem running on i-planet 2002-02-24 04:40 Hi, I have experienced similar problems when using Internet Explorer. Somehow, it does not how to display the PDF content it receives. Acrobat Reader has a setting that tells him if it should launch in the browser's window or in a separate one. Try to modify this setting. Maybe you can find more details on the iText site. Also, try to use other browsers to see if the problem persists. Thanks, Teodor By: Steven Blough - stevenblough RE: problem running on i-planet -solved 2002-02-25 09:27This actually ended up being a problem with the XServer not being installed and the classpath not being correct. I solved the problem by having Xvfb installed on the server because installing XServer wasn’t an option. Thanks Steven Blough Link to comment Share on other sites More sharing options...
