Re: XMLSpy - FOP
Matt, I'm sure Arved will have something to say about this, but are you subscribed to SourceForge's xslfo-proc list? Have you seen Arved's perl prototyping code? This is a *difficult* problem. A large part of the spec can be implemented relatively easily, but if you get the design of the first, say, 85% wrong, the last 15% becomes well-nigh impossible. I *have* been living off savings and credit cards for over 12 months now, initially struggling with the original code base before deciding to start from scratch, and I can say that I am beginning to get a handle on the design. Good luck. Peter Savino, Matt C wrote: I'm 99% sure there is a huge corporate demand for an FO-PDF engine right NOW. Those guys at RenderX are nice but unresponsive, their product is on par with FOP at best, and the're too busy to breathe selling $5k/CPU licenses! I'm about ready to quit and starting working on one myself. Anyone who knows the PDF spec inside and out and can live off savings or credit cards for 6 months is welcome to join.

RE: XMLSpy - FOP
Thanks Peter. I'm really glad to hear some positive news about the redesign! I'll try to get on that list and check out the code. I like reading Perl, it's therapeutic when you have to deal with Java all day long. I'm sure FOP is a very tough problem. I regretted the tone of that last email as soon as I spit it out. I'm just not having a very great day. I know from watching the fop-dev list for the last year or so that all the active players on FOP are very concientious, hard-working and know what they're doing. Maybe you can look at my little outburst as a rare window into the frustrations that some of the end users are feeling but have the tact to withhold. Just to give you an idea of my personal situation w/FOP, I work for a company of about 27,000 people. In the course of fighting to convince the higher-ups that we could do our little project just fine without Cognos or Crystal Reports, I've sort of become the chief FOP evangelist/programmer. (When you looked at our requirements and resources, building really did make more sense than buying--which is the whole promise of J2EE right?) We're trying to pull together a corporate culture that could have entire separate teams working on similar projects who didn't even know of the other's existstence. People are starting to look at my PDF solution. I'm just afraid they're going to look behind the curtain and see that I can't generate five 10-page reports at once (or one 100-page report) on one instance of Weblogic running on $80k worth of hardware--w/o running out of memory or coming to a standstill. I like where it sounds like you're going with the memory issues. I don't think the speed is a showstopper, but those out of memory issues sure are. I've upped my max-heap size to 768M. Anyone know of major pitfalls to this? (I have 1GB available per instance.) I guess even the roughest non-binding ETA on the redesign might help some of us sleep better at night - 6 mos? 1 year? 2 years? more? And just out of curiosity, why are you starving to finish this - love? future consulting gigs? both? Thanks again, that's all the rambling I have in me for now.

[ SNIP ] -End Of Original Message- Hi, Matt Let me clarify. The redesign is what Keiron & Karen (primarily) are working on. It is a redesign for FOP. What I started last fall is another project, which is intended to produce a C/C++ XSL-FO formatter. This is called xslfo-proc, and is on Sourceforge. I had a number of reasons for diverting my energies from FOP, and they had to do with limited free time last summer (due to intense real work) and a general burnout with how complicated FOP had gotten. xslfo-proc got off to a slow start, mainly because the company I was working for in real life went bust in October, and it's only this month that I got back into it. I did enough UML design last fall to realise that that was a waste of time. So a month ago I started working on a Perl prototype. I uploaded the first code yesterday but please don't expect this to actually be doing any layout yet. There is a lot there already, though, and at my current pace I expect to have some pretty good layout happening within a month. I have no intentions of abandoning FOP, but the redesign for FOP was and is critical, and only so many people can usefully do that - two max, IMO. When the redesign started I was out of the loop, so now I am waiting like everyone else. In the meantime I am devoting most of my efforts to xslfo-proc - it has a different approach and I hope it complements FOP rather than competes with it. My intention further down the road is to fold it back into Apache when the codebase is mature, there is a community built up around it, and the time is right. I'll second one specific comment of Peter's very strongly. I also believe that an XSL formatter project that is going to succeed has to tackle the whole problem. Formatting is not very modular, in other words. Not everything needs to be implemented right away but it sure needs to be considered, and a place for everything needs to be built in. The existing FOP shows us that retrofitting doesn't work. I'll welcome your interest in the xslfo-proc project if you feel like a break from Java. I don't mind admitting that since I work with Java every day in real life that the opportunity to get back to Perl (and C down the road) was not an unpleasant thought. :-) Regards, Arved

Re: XMLSpy - FOP
Arved et al, To clarify further: there are three re-design efforts going on. Keiron & Karen in Java, building on the existing code base. Arved doing a ground-up redesign in Perl (protptyping) and C or C++, as he has discussed. Me, in Java, doing a ground-up. Do not despair. If Flannery O'Connor is to be believed, Everything That Rises Must Converge. I believe that these design efforts will, if not converge, at least cross-fertilise one another considerably. You will probably have noticed that there is a lot of cross-talk between the principals. At the end of the day, I think that the best ideas will shake together in the bottom of the pan. However, I would hope for more. I can conceive of no reason why a common design will not work in Java, C, C++, Perl or any other language of choice. Implementation details may differ, but the same overall design should be realisable in any useful language. In that sense, I disagree with Arved. I think his work *is* contributing to the redesign of FOP. Obviously, I think mine is too. So, if you decide to get involved in xslfo-proc, the effort will not be wasted in terms of helping bring FOP to completion. Let me just strongly endorse Arved's comment about the oxymoronic "UML design", as in "design by UML". What a bizarre idea. It must be something consultants do. Peter Arved Sandstrom wrote: Hi, Matt Let me clarify. The redesign is what Keiron & Karen (primarily) are working on. It is a redesign for FOP.

What a bizarre idea. It must be something consultants do. -End Of Original Message- I should add, I attempted and rejected the use of UML in this particular instance. As I look back at it, this was more the fault of trying to use UML modelling tools on a 17" screen; by the time all the menus and side windows and toolbars have occupied screen real-estate you have a little quarter-screen window where you can visualize about 2 entire classes or a third of a reasonably useful sequence diagram. :-) So I gave up...the tools and my monitor failed, not the notation. I suspect that if I had used pencil and bristol board and/or a whteboard then UML would have worked out better. I consider prototyping in a high-level language to be detailed design anyway, which is what I really wanted to get at. I don't think there are too many mysteries about the high-level design of an XSL formatter anyway; you draw a couple of blocks and label them Formatter, Renderer, etc etc. :-) OK, OK, maybe not quite that simplistic, but by the time you get down to the problem areas in an XSL formatter it's detailed design. I don't discourage the use of UML but to be honest I've not seen it used much in real life for anything except class diagrams, or capturing requirements, and fairly abstract at that. I will likely end up describing the final prototype with class diagrams and some dynamic diagrams for documentation purposes, but I (personally) gain little from using UML over a prototype. Where the UML will come in most likely is when I look at the "final" prototype and make a determination as to how to port its lessons to C or C++. Right now I am leaning towards C. Regards, AHS

Re: calling fop from java
I´m working in something like that. I have an servlet filter that calls a JSP page that will return an xml file with a set of pre-defined tags. This xml file will be transformed into a fo stream with xalan using a xsl file with the fo definition of my tags. This fo stream will be then rendered with fop. (I hope that the English is correct...) I'm sending the code for the filter, the xsl that I have and a xml example for my tags. It´s is working, but the tags are still very limited because I´m still in the begining of the project. I´m also working in a wysiwyg tool to create the xsl file. Hope that helps.

with a set of pre-defined tags. This xml file will be transformed into a fo
stream with xalan using a xsl file with the fo definition of my tags. This
fo stream will be then rendered with fop. (I hope that the English is
correct...)
I'm sending the code for the filter, the xsl that I have and a xml example
for my tags. It´s is working, but the tags are still very limited because
I´m still in the begining of the project.
I´m also working in a wysiwyg tool to create the xsl file.
Hope that helps.

Re: calling fop from java
making html, from xsl and xml, with xalan, takes one row in java source
are you sure, that there isn't a simplier way to do that with xml, xsl
-> pdf???
please write down, what classes do you import
thanks

How to expand blocks in table in table ?
I need to show a set ( a lot of ) of key-value pairs layed out in grid. I took a table, in each cell I put a block with border and background set into which goes a new table with 2 rows each one cell. First cell holds the key wich is in smaller font, and the value . If the conent is to big for one line a linebreak is inserted an the cell gets bigger. Fine. Only the other cells of the top-level-table will not expand even with space-after.optimum and space-after set to 0. Question: How can I get the cells (and nesting blocks) of one row to be the same height ?

Not out-of-the box AFAIK, only MS-specific java programs will work as COM objects, or you need a COM-to-java bridge which is not very common and usually fairly hard to setup. It might be much easier to simply call FOP as an external process, something like "java . . . org.apache.fop.apps.Fop". Another option would be to use FOP over an HTTP interface: configure FOP as an HTTP servlet (using Cocoon for example) and call it from your ASP code: -ASP sends HTTP request to FOP backend -FOP responds with a PDF document which ASP can use Depending on your configuration FOP or Cocoon might have to make another request to your app to get the input XML - sounds a little complicated but is not hard to do once you get a clear picture of the interactions. This would give you a much more modular solution, and much less configuration headaches.

Then, to configure Cocoon you will need to understand the sitemap concept, it's not that hard for simple things, and it's XML-based, no programming needed. The skills you will need to get Cocoon running are more in the area of "life at the command-line", configuring stuff through XML files and using text-based log files to troubleshoot your installation. >. . . > The trouble is every month or so we have to print out the whole bunch > (about 600) of the things to post off to clients, which is why I need > a sturdy batch process. Existing examples of Cocoon sites show that it is ready for production. Depending on the complexity of your documents, FOP's memory requirements might get in the way, but that's a problem you will have anyway. Cocoon also has a command-line mode which I do not know well, but I think could allow you to generate your PDF docs to files directly.

Re: How to expand blocks in table in table ?
Torsten, You'll have to calculate how many lines are going to result from your comment text (Use length(.) on every comment and find the max number of lines in the xsl) Then do a white-space-collapse="false" and insert that many entries after the comments that do not meet the line wrap requirement.

Re: XMLSpy - FOP
Matt, Put this line at the top of your batch file: @echo "1:[ %1 ] 2: [ %2 ] 3: [ %3 ] 4: [ %4 ] 5: [ %5 ] 6: [ %6 ] 7: [ %7 ] 8: [ %8 ] 9: [ %9 ]" > t.out Then look at t.out to see what XMLSpy is sending to the batch file. Then try the same sequence from the command line to figure out what's going on and tweak the batch file to make it work. (That's how I made the batch file in the first place.) This is what I get: 1:[ -q ] 2: [ -xml ] 3: [ "C:\Fop-0.20.1\tmp.xml" ] 4: [ -xsl ] 5: [ "C:\Fop-0.20.1\pdf_master.xsl" ] 6: [ -pdf ] 7: [ "C:\Fop-0.20.1\Output.pdf" ] 8: [ ] 9: [ ] Chuck Paussa Savino, Matt C wrote: Thanks Chuck, I see I can actually use your workaround to go straight from XML-PDF with XMLSpy.

Re: Using FOP from ASP
I just set up FOP to run from ASP/VBScript, using WScript.Shell...
Unfortunately, it's non-trivial if you want to monitor FOP's output to
know if it succeeds or fails. I can talk about that if anyone's
interested but it'll get long...
However, to simply use the Run method to blindly run FOP, it shouldn't be
so bad... (disclaimer: untested code)
--
' Execute FOP to render a PDF. We execute it via a command-line
' interface provided via the Windows Scripting Host.
Dim Shell
Set Shell = Server.CreateObject("WScript.Shell")
Shell.CurrentDirectory = FOPDirectory ' Full path to where you put it...
' Now we have to generate a command line which will take our raw XML,
' process it with our template, and produce a PDF in the proper location.
Dim commandline
commandline = "fop.bat"
commandline = commandline & " -xml " & XMLFilename ' Set vars accordingly...
commandline = commandline & " -xsl " & XSLFilename
commandline = commandline & " -pdf " & PDFFilename
' Now we have our command line. Let's execute it.
Dim ResultCode
ResultCode = Shell.Run(commandline,,True) ' True = Wait for FOP to finish
--
BTW, I'd suggest upgrading to the newest version of MS Scripting if you
haven't already.

RE: XMLSpy - FOP
Arved, I'd love to help out with the Perl prototyping if you have any pieces that make sense to break off. I hear you about the UML. I think on some projects it's more about control than functional necessity. I'm protyping an HTML ad-hoc query builder right now. Once I get the user interface signed off, I just start fleshing the thing out until I get to the database. Here's the sequence I'm planning--HTML mockup->add JavaScript (button, form manipulation)->move to JSP->add Java code->add live Data->factor out from JSP the things that make sense into the Java middle layer (beans, maybe taglibs, output servlet, obvious things like Database Manager and value objects may be factored out sooner). I'm at stage 3, I'll let you know how it comes out. IMO, developing in JSP sure beats recompiling and bouncing the web app every time (although I just discovered how to do that w/o rebooting Weblogic). And I'll take some logic in my JSP over HTML in my Java classes any day. I realize this doesn't work on huge projects. And I think on things like workflow, modeling makes a lot of sense. But I believe there's some threshold, where the bulk of the complication is in the presentation, beyond which UML becomes more of a burden than a help. On my project, the mockup IS 80-90% of the model. I'm sure there are some top-down project manager Rational Unified Process/PEP types shuddering at the thought of a cowboy developer like me using the above process. I get the exact same shudder thinking about this project if we were starting design at the middle layer with a bunch of UML that mandates solutions (EJB, Design Patterns) before we clearly see the problem. I'm also on this new kick where I'm really big on breaking the logic into pieces and dispersing them over as many different technologies as possible (where it makes sene of course). Ideally when this little query tool is done, we will have user interface presentation logic in JavaScript/CSS/JSP, business and utility logic in middle-tier Java classes, data extraction and security logic in SQL stored procedures, and output presentation logic in XSLT (forked to HTML, PDF, XML, CSV). Now we have built-in modularity and multiple simple-interface "pinch-off" points w/o having to spend time contriving modularity schemes to force on the design. Very little of this relates to FOP by the way. I just like to ramble, it helps me think. -Matt > -Original Message- > From: Arved Sandstrom [mailto:[EMAIL PROTECTED] > Sent: Thursday, February 28, 2002 3:03 AM > To: [EMAIL PROTECTED] > Subject: RE: XMLSpy - FOP > > > -Original Message- > From: Peter B.

Is it possible?
I'm looking to use fop to render this document. I would like to know if is possible to render this document with fop. Thanks in advance and i'm sorry for my bad english. 730cmod.pdf Description: Adobe PDF document
FOP Servlet in Quiet MODE
Hi all, Would anyone please tell me how to run FOP servlet in quiet mode? I believe the messages displayed on console is draging down the overall performance. Your input is greatly appreciated. Thanks, David
RE: Is it possible?
I don't see why not. It would be an a lot of work, but not impossible. I assume you want to fill in the values as well? The only thing I see that I can't speak for sure about is the background image at the top of the page. But I guess you could always make the whole header an image if you have to. Here's a lab report we do in FOP that is not as graphically involved as your doc, but may give you an idea.
