Ok, I get it!!!! Finally I decided to install JAVA again:
Before I had JDK 1.5 with Tomcat 5.5.9, they were working well but I really don´t know what happend when I had to restart the server phisically and the graphics never comes up again. I was trying a lot of things to fix the problem, I tryed with -Djava.awt.headless=true property, with Xvfb but none of both works for me, so one of the last things I was thinking to do was to install the JPA Toolkit, I downloaded it and try to test it with a demo it has and again in my Windows system works fine but in linux doesn´t; reading in JPA Forums I understand it doesn´t work with JDK 1.5 so my next bet was to install jdk 1.4 and try to make JPA works, maybe with it my graphics goes up again, but when I install jdk 1.4 I probe my app and I get the graphics again so I was wonder becouse I don´t really install JPA Toolkit. So I thing the JDK 1.5 was corrupted or something similar and that´s why when I install jdk 1.4 it works again. As I don´t have a very nice reason to mantain JDK 1.5 and jdk 1.4 is working ok, then I have decided to keep jdk 1.4. alive with -Djava.awt.headless=true property setted of course .

I know the best way to set up this is by using -Djava.awt.headless=true but I had been tryin almost everything. The problem is my server is a remote rack server so it doesn´t have any display hw and as the -Djava... option seems desn´t work for me i am trying to use the Xvfb. By the way, could it be ok reboot the server in level 5?, does it have sense? Mauricio Fernández A. Ingeniero de Sistemas U.

BUT..... Hello, if, like i suppose from your various errors, jfreechart require awt/swing api and do draw on it, you need to run the tomcat server inside a X server, not only do you need to have fonts installed and corresponding X libraries (like your link suggest was problem), you also need to to have X server running and DISPLAY envirronement variable set accordingly. I would first suggest you start tomcat with CATALINA_OPT="-Djava.awt.headless=true" If, like i suppose will be the case, you get HeadlessExceptions when running like this, this mean you definitly need to run tomcat server inside a X environment. regards David Delbecq Mauricio Fernandez A. a écrit : >Thanks for your help > >Now I have reinstalled the XFree86 completly including the Xvfb and I can >start it (XVfb), to test if it is running I execute a xclock and I don´t get >any error, so I think it is running ok > >However, now, when I try to get the jsp wich must show a graphic I get >another different error: > > >java.lang.NoClassDefFoundError > org.jfree.chart.ChartFactory.createBarChart3D(ChartFactory.java:764) > com.Prueba.comandos.Graficador2.crearBarChart3DVertical(Graficador2.java:19 >6) > org.apache.jsp.jsp.grafica_jsp._jspService(org.apache.jsp.jsp.grafica_jsp:1 >67) > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) > javax.servlet.http.HttpServlet.service(HttpServlet.java:802) >.... > > >And in another web app in the same server the error is: > > >java.lang.NoClassDefFoundError > java.lang.Class.forName0(Native Method) > java.lang.Class.forName(Class.java:164) > java.awt.Toolkit$2.run(Toolkit.java:821) > java.security.AccessController.doPrivileged(Native Method) > java.awt.Toolkit.getDefaultToolkit(Toolkit.java:804) > com.actelion.control.Graficador.asignarBackground(Graficador.java:97) > > com.actelion.control.Graficador.crearBarChartVertical(Graficador.java:524) > org.apache.jsp.jsp.graficaVisitasMedicasEspecialidadCategoria_jsp._jspServi >ce(org.apache.jsp.jsp.graficaVisitasMedicasEspecialidadCategoria_jsp:198) > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) > javax.servlet.http.HttpServlet.service(HttpServlet.java:802) >.... > > >So having in mind that before Xvfb Installation the error was: > >http://www.jfree.org/phpBB2/viewtopic.php?t=14319 > >I think I am just with another different problem. > >Can somebody understand this? > >Thanks > >Mauricio Fernandez > > > > > >>> >>> >>> > >Hi Mauricio, > >I had the same problem.
