OPS looks for custom-processors.xml in the config directory.

 

One thing you could try is calling the custom processor from a pipeline run through OPS directly, rather than through Java, to see if that still gives you an issue

Hi

 

Could anyone tell me what rules OPS uses to decide where to look for the config/custom-processors.xml file?

 

I’m having trouble getting it to resolve my custom processor name to a JAR-backed implementation and any tips

or tricks would be most welcome.  Specifically I’m launching an XPL pipleline directly from my Java code, and that

pipeline references a custom processor which I have in a JAR on the classpath; I’m getting an exception of the form

 

oxf:<file path to my .xpl file>, line 34, column 44: Cannot find processor factory with name "{com.esprittechnology.xplatform.services.forms.ops.processors}exporter"

            at org.orbeon.oxf.processor.pipeline.PipelineProcessor.createConfigFromAST(PipelineProcessor.java:211)

            at org.orbeon.oxf.processor.pipeline.PipelineProcessor.readPipelineConfig(PipelineProcessor.java:470)

 

My pipline file looks like this

 

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"

          xmlns:oxf="http://www.orbeon.com/oxf/processors"

          xmlns:xplatform="com.esprittechnology.xplatform.services.forms.ops.processors"

          xmlns:fp = "com.esprittechnology.xplatform.services.forms.formsparams.schema.1_0">

 

….

 

    <p:processor name="xplatform:exporter">

…

 

 

And my custom-processors.xml file looks like this

 

 

<processors xmlns:xplatform="com.esprittechnology.xplatform.services.forms.ops.processors">

    <processor name="xplatform:exporter">

        <class name="com.esprittechnology.xplatform.services.forms.ops.processors.ExporterProcessor"/>

    </processor>

</processors>

 

 

I’d be interested to know also whether I can direct OPS to look in more locations
for this file.

 

Thanks

 

Alan

Hi Stephen

Yes -  I probably phrased the question poorly. What I’m trying to understand is where OPS looks for the config directory.

 

I was able to get OPS to resolve (and call) my custom processor when calling InitUtils.runProcessor from a commandline
application, by dint of having a subdirectory called ./config in the directory where I launched the Java VM.

 

Now I’m calling InitUtils.runProcessor from an EJB session bean running under JBOSS, and have created a config
subdirectory under %JBOSS_HOME%\bin, but OPS is not finding it.

 

Thanks

Alan,

The XPL engine uses the "oxf:" protocol abstraction to locate
resources through the resource manager.

When you start the XPL engine from the command-line, you have 2
options:

o Selecting a root directory for the resource manger, with the "-r"
   option.

o *Not* selecting a root directory by omitting the option, in which
   case the root of your resources will be the root of your filesystem.

Now the XPL engine loads custom processors from
oxf:/config/custom-processors.xml. So if you do not specify a resource
manager root, you will probably need to have your config directory
under c:/config or /config, which is not convenient.

So try using the "-r" option (you can even use "-r ." I think), and
make sure you have a config directory under the root specified.

Granted, this is not perfect, and maybe it would be a good idea, when
using the command-line, to be able to tell the XPL engine where to
find custom-processors.xml and properties.xml.
