BindException

Hello,

Is it possible to use FOP under Linux (without an X-Server or emulation), with JDK 1.3.x ?

I'm trying to use this configuration to generate non-graphic PDFs in a Tomcat 4.x webapp, but even this causes problems (I'm getting BindExceptions, as if it was trying to connect to the X-Server).

Thanks in advance for any help you could provide,

Guillaume

PS : here is what I get :

Weird it is - the stack trace that you sent clearly shows the problem 
happening when the HttpConnector class tries to open a ServerSocket, 
and it is hard to imagine what this has to do with FOP.jar. 

Maybe, just maybe, having FOP.jar in the classpath causes wrong 
versions of some classes to be loaded instead of the right versions, in 
which case you might want to make sure fop.jar is loaded last in the 
classpath. Maybe renaming it to zzz-fop.jar will do if the tomcat 
script sorts jar files by name when building the classpath.

You might also want to set tomcat's log level to the most detailed and 
try to follow exactly what's happening during initialization (or 
running diff on two logs, one with and one without FOP.jar).

I wish it were so simple, but it isnt !
Before adding some class creating some PDF with FOP, everything works perfectly.
Tomcat is configured on port 8080, but that's not the problem, and no other program is using this port.
The simple fact of adding fop.jar in WEB-INF/lib of my webapp causes this problem.
And as soon as I remove fop.jar, everything works fine again, like before!
Weird, isnt it ?

  Looks like tomcat is unable to start its HttpConnector, meaning the 
  port that it wants to use (8080 as standard, but check your tomcat 
  config) is already used by another program. Maybe by another instance 
  of tomcat if it wasn't stopped properly.

  Most likely this has nothing to do with the X server.
