Hi all
I am so sorry, but I don't understand the solutions for this error. I'm using red hat linux server v.8, j2sdk1.4.1_01, Apache Tomcat/4.1.18.
> I was trying to connect X11 Server on RedHad, the X11 server was up, but my application still failded with the same error.
> I don't know what "Xvbf" is, where can I find this option or program?
> where can I put this option
"D-java.awt.headless=true" in Tomcat, in what file?
> I am exporting a pdf from a servlet of my web application, I have this code:
Map parameters = new HashMap();
parameters.put("pr_Cupo", cupo);
parameters.put("BaseDir", reportFile.getParentFile());
bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, coneccion);

> In my application How do I utilize "the PJA Toolkit"? In where I have to change the code?

I hope that you can help me...

You don't need Xvbf or PJA if you are using java 1.4.1!

All you have to do is set the system property


One way to do it (certainly not the best way) would be to have a static method in the servlet that calls JasperReports something like

static {
System.setProperty("java.awt.headless", "true");

There is probably a better way to set the property through the tomcat configuration (setup) somewhere, but I am not familiar enough with tomcat to know where.
