Hi Alexi,

thank you for your answer.
It seems that with the 2.7.1 these kind of problems disappear.
It seems that this is the solution for the problem!

I tried to use the FOP trunk as well but I receive the following error:
[ERROR][org.apache.fop.apps.FOUserAgent.processEvent(83)]: Invalid property value encountered in src="url('D:\java\JPPF-2.5-node\resources\images\false_alerts\image.jpg')": org.apache.fop.fo.expr.PropertyException: Invalid URI specified (See position 57:143)

It reminds me an issue that I have seen yesterday at FOP's bugzilla.

Have you encountered this error as well?

Hi,

As you wrote, the problem occurs during the transformation of XML + XSLT to 
XSL:FO and therefore this is not related to Apache FOP. I had a similar issue 
some years ago and the problem was a concurrency issue inside Xalan. Try 
upgrading to Xalan 2.7.1 were this was definitely fixed. Note that Xalan may 
also be loaded from the 'endorsed' directory of application servers.

Having said that, there are indeed a few concurrency issues in Apache 1.0 which 
are fixed in FOP trunk. They don't seem to be related to this but if you have 
many threads running , I am sure you will sooner or later encounter them. If 
this does not solve the problem, then explaining or attaching code on how you 
use Apache FOP will help.

Hello,

I found this link related to SVG: 
http://xmlgraphics.apache.org/fop/trunk/graphics.html#svg
based on that I use this:
<fo:external-graphic src="url('{$link}')"  content-width="scale-to-fit" 
width="20mm" />

The link is an absolute path to a JPEG file.

This erroneous behaviour happens not only at the URI of the image but in other 
places.
For example I have hard-coded in my XSLT the following '8pt' and the generated 
FO contains the problematic 'pt8pt'.
I print the whole FO when an error happens in order to check it.

Please let me know if you need more information.

Klearchos

Hello

I have similar things but as far I can remember this was always related to svg 
as part of an fo stylesheet.

I should/could dive into the mail archives (and perhaps) bugzilla to refresh my 
memory, as I remember there were discussion on this, but perhaps you can 
indicate whether you are using svg at all in your fo?

Dear FOP users,

I am using the FOP version 1.0 under Windows x64.
Lately I have integrated JPPF in order to regenerate my PDFs faster and I 
experience the followings strange errors.

For example inside the XSLT I place 8pt but the error in the console outputs 
(pt8pt):
[ERROR][org.apache.fop.fo.properties.PropertyMaker.convert(148)]: Unknown 
length unit 'pt8pt'

This kind of behaviour happens at other places as well:
[ERROR][org.apache.fop.apps.FOUserAgent.processEvent(82)]: Invalid property value 
encountered in color="whitewhite": org.apache.fop.fo.expr.PropertyException: 
null:56:15: No conversion defined whitewhite; property:'color' (See position 57:85)
Only white at the XSLT.

[ERROR][org.apache.fop.apps.FOUserAgent.processEvent(82)]: Invalid property value 
encountered in background-color="#6777cf#6777cf": 
org.apache.fop.fo.expr.PropertyException: null:56:15: No conversion defined 
#6777cf#6777cf; property:'background-color' (See position 57:100)

[ERROR][org.apache.fop.apps.FopFactory.resolveURI(755)]: Attempt to resolve URI 
'F:\JPF:\JPPF\Node1\resources\images\na_b.gif')' failed:
Here the URI is given correctly at the XSLT processor: 
F:\JPPF\Node1\resources\images....

These kind of errors continue.

Any pointer would be really helpful.
I am considering using the trunk version as well in order to close some other 
reported and patched bugs of FOP 1.0

Klearchos
