I've just downloaded Babeldoc and am trying to work my way through the examples. I'm finding either the configuration information pretty light, or I'm reading it wrong. In any case, the scanner example doesn't do anything at all - just sits there after I copy the file stats.xml into c:\tmp\in. I'm on WinXP Pro, set up my path and BABELDOC_HOME env. vars. etc. The doc creation example works just fine, but the scanner example does nothing.
I then tried the Higgsbros example (setting classpath to c:\Higgsbros;%classpath% and get
<2003-05-18 20:49:09,320> ERROR [main] : Error starting scanner: com.babeldoc.scanner.ScannerConfigurationException: No scanner threads provided
funny thing is that when I close the console window and re-open another to get a clean environment, I get the same error message trying to run the basic scanner example until I blow away the directory and re-extract it.
Clearly I'm doing something wrong. Can you point me to documentation on the scanner parameters and configuration information beyond what's in the User Guide?
Thanks,

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
There are two ways to start scanner with the given configuration.
1.
- Set BABELDOC_HOME environment variable to point to build folder of Babeldoc installation. So if you have unpacked Babeldoc*.zip into c:\babeldoc, set your enviroment variable to c:\babeldoc\build. You must do this in order to Babeldoc work correctly.
- Add %BABELDOC_HOME%\bin to your Path environment variable.
- Change your working directory to example you want to start. Examples can be found under build\examples folder. Your working folder should contain other folders like (pipeline, scanner...)
- Now start scanner with command 'babeldoc scanner'
2.
- Set BABELDOC_HOME
- Set BABELDOC_USER variable to folder of example you want to start
- Start %BABELDOC_HOME%\bin\babeldoc scanner
Please let us know if you still have a problems.

Thanks for the quick reply. I had done most of that in (1) with the exception of changing to the directory of the example. The BABELDOC_USER variable (2) is new to me - I didn't see it in the doc, thanks.
Anyway that at least gets the examples to start, but the scanner just sits there. In the example in the white paper, I copy stats.xml into the c:\tmp\in directory and nothing happens. In the Higgsbros example I created an order.csv file and dropped it into c:\tmp\orders\in. The config files seem to correspond to the doc.
Any ideas?

I have downloaded babeldoc 2 days ago and today I am experiencing the same problems as Bill is having, that is scanner starts but doen't do anything even if the file is in the "in" directory.
Any Suggestion ?
Also, is there a special pipeline stage which allows to pass a document to a java class supplied by the user ?
thanks

Yes, of course. You can extend almost every Babeldoc component. Writing your own pipeline stage is quite straightforward, you should extend com.babeldoc.core.pipeline.PipelineStage class and implement its process method. You should also add an entry in service/query.properties.
I think there should be info about this in developers guide.

I found the where is the problem. Your configuration is OK, there is the bug in Babeldoc 1.0.0 version that will be fixed with 1.0.1 version
Problem is in using filter property. This property is used for specifying regular expression filter for filenames. This property is optional and by default all files should be accepted. But, because of bug this is not true in current version. To prevent it, set filter to accept all files (some other regular expression that matches files you want to process) by putting something like this in your scanner config file.
directory.filter=.*
Please, let me know if this helps.
I have also submited new bug report in tracker with this bug.

I was getting pipeline not found. I think that I don't clearly understand the relative referencing in configuration files. And I don't understand when something is a name (eg. for a pipeline like: Higgsbros) and when it's a directory or file reference.
example:
I have in
c:\Higgsbros\scanner\config.properties:
directory.type=directory
directory.period=10000
directory.inDirectory=c:/tmp/orders/in
directory.doneDirectory=c:/tmp/orders/done
directory.pipeline=higgsbros
directory.filter=.*
(which is finding the file in /in just fine and attempting to start the pipeline now) I assume from this specification that there should be a c:\Higgsbros\pipeline directory and in it a pipeline prefixed by "higgsbros". So I have in
c:\Higgsbros\pipeline:
higgsbros.type=simple
higgsbros.configFile=c:/Higgsbros/pipeline/simple/order-outbound

c:\Higgsbros\pipeline\simple\order-outbound.properties:

mypipeline.type=simple ; Configured by properties file
mypipeline.configFile=pipeline/mypipeline
This tells babeldoc that there is a pipeline called "mypipeline", its a "simple" pipeline (configured from a properties file as opposed to an XML file) and the location of the configuration file is: config/pipeline/mypipeline.properties. Note that all the configuration options start from a "config" directory.

I now have most of Higgsbros working - I had a few typos in the convert and the xsl files and I inserted some new pipeline stages to FileWrite the documents in intermediate stages so that I could see what was happening, but it seems to all work (I removed the [1] from orders[1]/...)
I'm still having problems with the mail reader, writer works fine. The mail reader worked earlier at one point when I was on the same network as the server and now doesn't again. (I 'm on a laptop and move between networks.) When I watch my mail server, the connection opens, the scanner detects the document, and then just hangs - the connection between the mail reader and the mail server stays open, then 30 seconds later, the scanner opens another connection. From that point on there never seems to be more than 3 connections open, but there is always one. Scanner just keeps reprinting the message that 1 document was detected.
Hope this helps.

Can you send here your scanner configuration (scanner/config.properties file) for both examples you try to run.
Also send output you got after starting scanner if any.

What problems do you have with pipeline?
I was getting pipeline not found. I think that I don't clearly understand the relative referencing in configuration files. And I don't understand when something is a name (eg. for a pipeline like: Higgsbros) and when it's a directory or file reference.

emailer.smtpMessage=${document.toString()}
Now, should the "test" directory be a sub-directory of
C:\Higgsboro\pipeline\simple?
or of c:\Higgsboro? any way, I'm not sure it's finding the pipeline.
The exception I get is:

Hello Bill,
The pipeline configuration is routed out of the config/pipeline/config.properties file. This lists each of the pipelines, the pipeline type and the configuration file for each one. So for purposes of illustration:
mypipeline.type=simple ; Configured by properties file
mypipeline.configFile=pipeline/mypipeline
This tells babeldoc that there is a pipeline called "mypipeline", its a "simple" pipeline (configured from a properties file as opposed to an XML file) and the location of the configuration file is: config/pipeline/mypipeline.properties. Note that all the configuration options start from a "config" directory. You can call your configuration directory anything you want, but it must be either in the CLASSPATH (not suggested) or in the BABELDOC_USER environment variable.
Well, that worked,(changing to relative reference) - I'm surprised that the
c:\Higgsbros\pipeline\config.properties file can't use a full path reference(e.g.):
higgsbros.type=simple
higgsbros.configFile=c:/Higgsbros/pipeline/simple/order-outbound
Now the error that I get is:

I can't find the documentation for FlatToXML, but it's in the usage white paper example. Has this changed?

Not intentionally!

I am also trying to use the mail scanner with the following lines as the second scanning thread in my scanner\config.properties file:

mailbox.pipeline=higgsbros
mailbox.period=30000
mailbox.protocol=pop3

And, there doesn't seem to be an option to delete the message from the mailbox, as it just keeps on detecting the mail again and again and doing nothing.

Excellent news Bill!
Can you provide some details about your email server? I have tested this with MS Exchange. Another idea is that we try and duplicate your issues. This should isolate some problems. If this works, join the babeldoc-user list and we can set this up.
Hi,
