For some reason PD4ML suddenly doesn’t function on my system (which happens to be Macintosh).
I have 3.8.0
The only reason I can think of is my recent system update to Lion. Anybody else had a problem with PD4ML on Lion?
The problem is pretty odd. I get no errors in my logs.
After turning on debugging, in one case it tells me that it’s created a .pdf when it’s done nothing at all. Then everything just stops. It took me ages to work out that the problem was with PD4ML because there were absolutely no errors in my logs anywhere.
In another debugging – for a different page – the debug just tells me the version number of PD4ML then does nothing else. Nothing is produced any more in any of the programmes that use PD4ML, at least in the tagged
versions. I haven’t tried to check the .java api.
If anybody’s got any ideas, they would be very welcome.April 20, 2012 at 15:12#28945
Could it be a 64-Bit issue?April 23, 2012 at 18:08#28946
I’ve just updated JDK on my Mac workstation to the most actual state and tested PD4ML – everything works fine (as before).
Currently Lion comes with no JDK – you need to install it manually. Also Lion does not support 32bit JDK anymore. So I suspect you installed Lion, but JDK remains from your previous installation, which is not compatible with Lion.
The actual JDK can be downloaded from http://connect.apple.com – please give a try.April 24, 2012 at 05:46#28947
The JDK works fine, I use it for Tomcat, Spring and work with it as usual. It’s also been updated automatically a couple of times since I got Lion.April 27, 2012 at 15:21#28944
Please help, someone.
Presumably something is simply missing, but there are no log messages at all to give an idea. Probably the Lion idea is a red herring.
I did a complete reinstall of Snow Leopard a couple of weeks before updating to Lion and it may have happened then.
Here’s a very simple test below. The code is correct, of that I’m certain.
The debug just prints out “version: PD4ML 380 Pro” and then it all hangs….
All the correct .jars are on the classpath- I currently have:
Any help would be very gratefully received.

The JSP sample is very basic and as I see is absolutely correct. The library set is also complete. So obviously something is wrong with the environment.
If you are absolutely sure there is no error messages and stack traces in both server STDOUT and STDERR logs, please try to run an offline test:
java -Xmx512m -jar pd4ml.jar
It should run PD4ML in GUI mode. Try to open an HTML and to convert it to PDF. Does it work?April 30, 2012 at 08:54#28949
Thanks for your help.
I’ve been trying to run the command-line pd4ml class but whatever I do I get:
java.io.IOException: Cannot run program “/Applications/Preview.app”: error=13, Permission denied
I’ve created a folder with completely open permissions to everyone, and I run the pd4ml class from there.
I also changed the permissions for the Mac preview app so that it has permissions to be run by any user.
The pd4ml class will open and show my simple html file when I press GO.
But will not create a .pdf when I press PDF – for the reason shown above.April 30, 2012 at 09:05#28950
P.S. There have never been any messages at all in my Tomcat stdout and stderr logs. Complete silence. And any calls to pd4ml just hang forever, without timeout.
My Lion update was quick and practically painless, which was perhaps too good to be true. I’ve had no problems at all with any other programmes.
Presumably something is missing, however. PD4ML doesn’t depend on any system graphics does it?April 30, 2012 at 12:22#28951
> The pd4ml class will open and show my simple html file when I press GO.
It is a good sign. It means PD4ML works and renders HTML (in the case not to PDF, but to Image output device). I guess it also produces PDF to a TMP directory, but it cannot start a viewer application for some reason.
The problem with Tomcat still has no good explanation. I would recommend to try to configure a progress monitor:
It should help us to determine at which conversion phase it fails.May 7, 2012 at 08:29#28952
Ok, tried the Progress Meter
This is all I get, I’m afraid:

My colleague who also has just installed Lion has the same problem, exactly the same.
I have tried updating to 3.8.0fx4 but it made no difference.May 15, 2012 at 12:44#28954
Currently on my workstation is installed OSX 10.7.2 – no problems with PD4ML at all.

Pd4Cmd does not try to run Preview.app. Probably you are trying to convert with PD4Browser. Run Pd4Cmd instead:

Sorry for the delay, I hadn’t gone to sleep, I was on holiday.
Thanks for your continuing help.
The following command produced a nice pdf:
java -Xmx512m -Djava.awt.headless=true -cp ./pd4ml.jar Pd4Cmd ‘http://pd4ml.com’ 1200 LETTER -bookmarks HEADINGS -pdfforms -debug -out /tmp/pd4ml.pdf
The only question is: why doesn’t it produce anything from Tomcat6 (which is also headless)? We get nothing from either API calls or tagsMay 21, 2012 at 18:08#28956
Does your product or Tomcat installation includes GWT-DEV.jar?May 21, 2012 at 21:35#28957
No, we don’t use GWT, and the .jar you mention is not among our libraries.
