Re: Multithreaded failure
I moved the creation (and destruction) of the Driver object inside the
method. Also I had forgotten that in Apache SOAP, you can control object
lifetime. So I changed it from Application to Request, so now each request
gets a fresh instance of my class.
This works, but I'm not happy with it. My question is this, if I have a
Driver object as a global inside my class, will it be trounced by another
instance running in a different thread?

Re: Some comments on the build system
Keiron, I don't know the nuts and bolts of CVS, but I always assumed that tags were somehow related to the RCS symbolic name, accessible via $Name$. $Name$ has some peculiarities due to the fact that there is not a unique name attached to the current version; I think it is set in the output files from the symbolic name under which the file is retrieved. I don't know, off hand, what the deault behaviour is. I can check the RCS characteristics here. Do you want to install $Name$ in one of the CVS files and see what it looks like when retrieved?

Question for FOP
Title: Question for FOP Hi, I just successfully run the examples (simple.fo) provided in 'fop-0.20.3-bin.tar.gz' file under fop-0.20.3\docs\examples\fo subdirectory in the command prompt and I got a pdf file successfully . I still have the following question: 1. How can I view the source code for this example? 2. I also looked over all the rest of the folders included in 'fop-0.20.3' and there are a lot other folders like design, html-docs(some .html files in it), xml-docs(some xml files in it), etc. What are all those files used for? 3. Actually what I want to do is: convert a XML file to PDF file and display this PDF file on the web page. How to do this? I am new to this and really like to have your advices and help. So if you could provide further information, I would appreciate it very much.

List, I'm having a failure of FOP 0.20.3 while in a multithreaded environment. FOP is being called within the context of a SOAP RPC. As soon as I hit the process w/ a second thread, I start getting a FOPException "org.apache.fop.apps.FOPException: root must be root element".

The LGPL license is much more restrictive than the Apache license which has almost no restrictions at all. AFAIK, there is no problem in integrating FOP into an LGPL product. But if you want FOP to be licensed under LGPL you have a problem, because I think that the Apache license doesn't allow changing the license of it's software. My question is why does OOo require FOP to be LGPLed? You can integrate it into OpenOffice without it being LGPL. If you do this it would also be fair if you contribute changes to FOP back to the Apache tree. Just as another side note: I consider the LGPL and GPL a bad license. LGPL projects can profit from code under more liberal licenses like BSD, MIT, X11, Apache, but the other way round is not possible. There are other drawbacks also...

We recently had this discussion in reverse about the possibility of incorporating iText PDF library into FOP. This is a non XSL:FO library which helps you generate and process PDF files. In the end I think we had to turn down iText's generous offer since its code was licensed in an incompatible way with Apache FOP. However if your OpenOffice code uses LGPL and iText uses LGPL I see no problems. http://www.lowagie.com/iText/ I guess the next question you need to ask yourself is do you require XSL:FO capability?

The Apache license makes the code usable in any way, as long as you give proper credit and don't blame Apache for problems. AFAIK, the problem lies in the *GPL license, which is more restrictive; my personal suggestion is to check the LGPL license and ask the authors of that license. IIRC GNU states that Apache and *GNU licenses are incompatible for them, but don't take my word for it.

License Issue Inquiry
Greetings, I hope this is the proper place for this question to be submitted. If not, please direct me to where I need to go. I am taking it upon myself to submit a query regarding the Apache Software License that FOP is licensed under. There is some big interest currently in the OOo (OpenOffice.org) community with respect to finding a cross-platform, uniform and integrated method for providing PDF document creation, and FOP looks like it could be the answer. The only question is, can OOo use it? OOo requires that anything integrated into its source code be made available to them under the terms of the LGPL license. What would be required in order to allow a version of FOP to be licensed/sub-licensed/dual-licensed under the LGPL?

RE: Some comments on the build system
Hi, Peter
I personally agree that the properties don't need the XML+XSLT approach.
Even if one leaves aside the aural properties there are over 250 properties,
and on close inspection the commonalities are limited. I believe the largest
group size of properties that are identical is 4. Many properties have extra
constraints (they interoperate with other properties, for example), they
accept different combinations of input generic types, percentages have
meaning only in the context of the property, and so on and so forth.
One could come up with a super-sophisticated XML+XSLT system to embody all
this, but why bother?
I'm not going to bad-mouth the current system that FOP has. I acquiesced at
least implicitly in the choice to at least continue with it, at an early
stage. But I now believe that the right place for a lot of logic related to
properties is actually in the properties. I think an XML+XSLT approach
pushes a lot of that out into places where it ought not to be.
Most of the common handling has actually little to do with the properties
per se - it has to do with expressions and datatypes. This is not the same
thing. An XSL property is not a datatype, IMO, and shouldn't be regarded
that way.
I don't think it's a pressing issue unless someone then immediately proposes
and moves forward with work to make the properties rich, interesting things.
It's not really an IDE issue - there are IDEs that handle the current FOP
setup just fine.
I also agree that ease of making changes to properties is not a compelling
argument for XML files, nor for using XSLT to generate the code. The
properties are simply not that similar. So you may as well work on Java
properties files directly. And since properties _are_ what make XSL, if
there are significant changes in properties in the spec then the disruption
is going to be widespread.
I agree with Keiron's observations regarding the other point, about
versioning. Our numbers are release numbers (major, minor, patch, plus stage
info, as he puts it), and these require human decision-making. You can't
automate release numbers sensibly.
Anything else Ant supports (timestamping, token filtering, build number
incrementing) makes a lot of sense in the right contexts, mostly in the
sense of configuration management and builds.
I'd like to see a stronger link between the release number in the build.xml
and the presence of a matching tag in the CVS, myself. I've been personally
guilty of forgetting to tag the CVS when buildng a distro and it's because
there was no mechanism to jog my memory. I don't think the tagging itself
should be automated but some aspect of the source code retrieval prior to
building a dist* target should be dependent on the presence of a matching
tag. Let's face it, right now we have no configuration management at all -
maybe this isn't much better but at least it's something.

Subject: Some comments on the build system
Fops,
I would like to see the build system overhauled. The overall objectives
of the overhaul would be to simplify the build process and decrease
barriers to entry for would-be developers. The tactical objectives
would be to eliminate XSL from the build, and to generate the classes
directly from the source tree. The advantages of this approach are, I
think, obvious. For a developer using an IDE/JDE, the source tree
associated with the classes whose behaviour is being observed would be
the same source tree to which changes are being made, and the same
source tree from which commits would be made. Eliminating XSL, and
expressing the system entirely in Java means that, as far as development
is concerned, what you see is what you get. There are no invisible
shenanigans going on behind the build.
I have not gone over the XSL with a fine-toothed comb, but what I have
seen is enough to be able to give the flavour of the argument.
Basically, if you feel the need to generate Java from a combination of
XML and XSL, you should make your Java look more like your XML, and less
like the output from your XSL. The neat data characteristics of the XML
can and should be expressed more or less directly in Java.
Font generation is simple to translate into a static reference HashMap
from names to codepoints, set up with a static{} block, and some further
static{}s to set up the width arrays.
Properties are a fascinating topic. To me, the fact that Properties
virtually demand some kind of code generation is proof enough that the
approach is wrong. But more of that another time. Let's say that you
do need some help to set these things up. How many times do you need to
do it? Isn't once enough? The majority of the class files having been
set up, what varies?
Create the base files, and check them in to CVS. Then put the XML and
XSL aside as a once-useful historical oddity. Unimplemented properties
will pres
vertical alignment
I must be missing something, but for the life of me I can't figure out how to create a single page with vertically centered text. I want to create a title page which will have the text Blah Blah by Whoever on three lines, all grouped together in the center of the page without explicitly setting how far down on the page it is. I've set the vertical-align attribute of a block but it's still stuck at the top of the page. If horizontal centering is so easy then why is vertical so hard? Thanks in advance, - Joshua ... but I still haven't found what I'm looking for. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
PDF viewing with IE 5.
Hi All,I recently started to use fop
and came across the problem with IE notdisplaying the PDF. After
looking around and checking other peoplessolutions it seems it was due to
the filename extension required to be .pdfand the content-length header
needed to be set. To get the content length Ineeded to buffer the
output; and used a ChunkByteBuffer class to do this.This is instead of
allocating a byte[] as the current FopServlet does. TheChunkByteBuffer
class I have released as LGPL to be added to the FOP projector the embedded
example so that others don't need to go through the samepain. :) I
hope you find it useful for the project.This ChunkByteBuffer could be
used in conjunction with checking the requestheaders for the type of browser
being used by the client. If the browser isIE then use the buffer,
otherwise stream directly. The buffer also uses astatic vector of free
chunks so that data does not need to be reallocatedfor every buffer
used. The free chunk vector currently only grows, andprobably needs
some timed cleanup mechanism. If you implement this let meknow.
You can find the code here:www.livemedia.com.au/ChunkByteBuffer.javaI
don't have an example of how to use it as my current code uses lots
ofexternal classes. It would go something like this in the
FopServlet.javaexample.ChunkByteBuffer cbb = new
ChunkByteBuffer();OutputStream bout = cbb.getOutputStream();Driver
driver = new Driver( foFile, bout );driver.setRenderer( Driver.RENDER_PDF
);driver.run();bout.close();response.addIntHeader(
"Content-Length", cbb.length() );OutputStream out =
response.getOutputStream();InputStream in2 = cbb.getInputStream();byte
buffer[] = new byte[2048];while( (length = in2.read( buffer, 0, 2048)) >
0 ){ out.write( buffer, 0, length
);}in2.close();out.close();To make sure files had a .pdf
extension I used the mod_rewrite engine ofapache. My current test is
using a static filename as follows:RewriteRule ^/fred.pdf$
/print/servlet/printServlet [P]If you find it useful in what you're
doing or find any bugs let me know.Regards,David.PS I'm
currently looking for some contract work.. anyone?

Problems using table-header with FOP 0.19
I have written this code: http://www.w3.org/1999/XSL/Format";> Test Table Header 1 Test Table Header 2 Test Table Header 3 Test Table Body 1 Test Table Body 2 Test Table Body 3 I wrote two tables: one for blank space and the other one to write data. If the property space-before of the first table has a value of 500pt, it is shown right but if the value is 450pt (like now), the table header is getting lost. Could anybody help me?

fo:basic-link does not work in xsl-region-before?
Hi, does anyone know if this is a FOP bug? It appears to me that a basic-link cannot be used in the region-before, as in the following snippet: http://www.abc.def";> www.abc.def ... BTW, this was a bug in FOP 0.17, marked #964 in bugzilla. Thanks, Costantino - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
AW: Designing PDF extensions: form fields
Hi Keiron, Let's fix a DESIGN GOAL. What can be realized in which time frame? I see 2 ways to go ahead: 1. Low level implementation using native PDF syntax: users have to learn PDF syntax and to some extent PDF file structure. They can try experimentally everything with the risk of invalid PDF in the document test phase. The document development might look like this: - get documentation: PDF reference manual or see PDFmarks in http://www.math.uakron.edu/~dpstory/tutorial/pdfmarks/forms.pdf - develop document without form fields - use Acrobat to add the form fields to the document - view the PDF document in ASCII e.g. with Windows WordPad and copy form field PDF objects into FOP markup - test, modify FOP markup 2. Perfect, complete XML syntax for PDF forms covers all functions. Perhaps XHTML could do this job. The system is fully documented, so that users never have to care about PDF internals (my favorite reference document has 96 pages). The PDFextension takes over FOP properties and uses existing PDF methods. Additional properties needed for PDF form fields are handled. Of course a clean system (2) is preferable. Where is the expert to take over this task? Not very elegant system (1) can be set up within 1 month assumed the pdf library offers an API to allow PDF extensions - the base for other developments. Once priorities are set, technicalities will be solved efficiently. Hansuli Anderegg, Zurich, Switzerland - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Problems printing PDF files with SVG images
Apologies if you have already received this, the original was bounced back as the attachments were too large. I am trying to print a PDF file which contains an SVG image generated by FOP 0.20.2. The SVG image consists of bar chart with text labels on each axis. The problem I am encountering is that when I set FOP to use PDF fonts (PDFFonts.pdf) by adding the strokeSVGText false value to the userconfig.xml. The label text does not appear when printing the PDF file, yet when I view it in Acrobat Reader 4.0, it appears fine. When I use SVG (SVGFonts.pdf) fonts rendering the text labels. The text labels appear "grainy" in the PDF viewer, but print out fine. I am using FOP as part of a web server based application which allows users to be able to view the PDF documents in a browser and print them. I have setting the "Smooth Text and Images" in the Acrobat settings, but this has not altered the rendering quality of the text, using SVG fonts. Is there any way I get the text in the PDFFonts.pdf example to be printed, by making a change on the server ? ( I don't want to have users changing their acrobat settings if at all possible ). The SVG image is generated by batik.jar, provided with FOP.
