Re: Problems with graphics on Tomcat 5.5.9
Cabe suponer que has mirado la linea 211 de tu'Graficador2.java'?, ...
parece corresponder a lo primero escrito por ti y, frecuentemente, esto da
una pista.
Parece involucrar un problema de Acceso de Java -muy pijotero siempre-, ¿es
todo accesible?.
Graficar = = java.lang.NoClassDefFoundError:

Re: Problems with graphics on Tomcat 5.5.9 OK!!! 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.

RE: Problems with graphics on Tomcat 5.5.9 OK!!! BUT.....
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.

Re: Problems with graphics on Tomcat 5.5.9
You need to install the X11 libs for X. The Java Advanced Imaging API calls the X libs on Linux to get font and scaling data. You can try setting the JVM java.awt.headless property to true. This will work for some instances. But installing the X libs installed on your server is a more reliable option. To set your java.awt.headless as true use the following line. System.setProperty(java.awt.headless, true); System.setProperty(java.awt.headless, true); Mauricio Fernandez A. wrote: Hello I have a web App with some jsp´s showing graphics generated by jfreechart, in my windows dev station it works fine but in my linux production server it was working fine to some days ago and now it doesn´t.

RE: Problems with graphics on Tomcat 5.5.9
Do you refer to X11R6? I have a /usr/X11R6 dir in my server but when I do #rpm -q X11 package X11 is not installed #rpm -q X11R6 package X11R6 is not installed And when i do #whereis X11 X11: /usr/bin/X11 /etc/X11 /usr/lib/X11 /usr/include/X11 So I don´t understand what is about the X11 libs. any idea? thanks!

[OT] RE: Problems with graphics on Tomcat 5.5.9
Completely OT, but: If you're going to search for X11 packages with rpm, use rpm -qa | grep [package name or part]. I believe rpm -q [package name] is very limited and only tries to find a package named exactly as you enter it. --David Do you refer to X11R6?
