GREAT!

 

I used Xvfb now but headless support is better. I think it is only available in JVM 1.4 but thats OK.

Hi,

Is the file: "/etc/tomcat4/etc/tomcat4.conf" create by yourself ?

Because I don't know where it is.

 

I install tomcat here "/usr/local/jakarta-tomcat-4.1.18/"

Where should I add "CATALINA_OPTS="-Djava.awt.headless=true" ?

 

Thank you,

 

neltan

Thank you. I get it now.

I update my "/etc/rc.d/rc.local"

 

# Set JAVA_HOME for Tomcat

JAVA_HOME=/usr/local/j2sdk1.4.1_01

CATALINA_OPTS="-Djava.awt.headless=true"

export JAVA_HOME CATALINA_OPTS

When running on RedHat 7.1 and SDK 1.4.1_02 I get the following:

 

Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

 

This ocurs once after a Linux boot. Subsequent calls to JasperReports result in:

 

java.lang.NoClassDefFoundError

at dori.jasper.engine.fill.JRFiller.fillReport(JRFiller.java:109)

at dori.jasper.engine.JasperFillManager.fillReport(JasperFillManager.java:217)

at dori.jasper.engine.JasperFillManager.fillReportToFile(JasperFillManager.java:138)

at dori.jasper.engine.JasperFillManager.fillReportToFile(JasperFillManager.java:124)

 

I have made the suggested change to CATALINA_OPTS. These synptoms do not occur on windows. The JR jar file is in <my-app>/WEB-INF/lib

 

Is this an XServer configuration problem?
