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

2005-10-11 Thread Mauricio Fernandez A.
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

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.awt.Toolkit.getDefaultToolkit(Toolkit.java:804)

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:

I think I am just with another different problem.

Can somebody understand this?

Hi Mauricio,

I had the same problem. The solution is as follows:

1. Download and install a virtual frame buffer
   Where to find and how to install:
   http://testdrive.mapinfo.com/TECHSUPP/MIPROD.NSF/0/a832a07452b9a0e385256f
8000760f68?OpenDocument

2. Do not forget to create a script to start xvfb - you will find the script
under the link above

3. Edit the startup.sh or catalina.sh as follows:

#export DISPLAY
export DISPLAY=IP_of_your_machine_where_Tomcat_is_running:0.0
export CATALINA_OPTS=-Djava.awt.headless=false

4. Start xvfb

5. Restart Tomcat

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.

Sorry, it's CATALINA_OPTS  (with the *S*)

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

2005-10-11 Thread Mauricio Fernandez A.
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?
