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

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
Trying again to make the graphics appear in my web app, I did a test web app
and I had been trying to start the Tomcat with -Djava.awt.headless=true
option as I read in some forums
#export CATALINA_OPTS=-Djava.awt.headless=true
#/usr/java/jakarta-tomcat/bin/startup.sh
But they do not appear either
The web test app can be found here http://www.actesoft.com:8080/Prueba/jsp/
and the wanted result after click on Graficar is something like this
http://www.actesoft.com/ejGrafico/ (static page)
Also I have try to insert in the Graficador.class constructor the next
System.set/getProperties lines
public Graficador(String Path){
super();
this.contexto = Path;
this.background = null;
//System.setProperty returns the current value before assignment
String vrPropiedad = System.setProperty(java.awt.headless, true);
// Log the before assignment value to a log file to debug
logger.debug(BEFORE = java.awt.headless = + vrPropiedad);
//and log the after assignmet value to a log file too
vrPropiedad = System.getProperty(java.awt.headless);
logger.debug(NOW = java.awt.headless = + vrPropiedad);

Maybe you can try with the .zip distribution if your so is Windows or .tar.gz if Linux or whatever you want/need from http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi If you don´t know which one download read the README http://apache.org.es/jakarta/tomcat-5/v5.5.12/README.html Mauricio Fernandez -Mensaje original- De: krux mania [mailto:[EMAIL PROTECTED] Enviado el: lunes, 10 octubre, 2005 19:37 Para: tomcat-user@jakarta.apache.org Asunto: silent install of Tomcat Hi, I need to install tomcat 5.0.28 silently for my application.

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); - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
