Groovy Console Help Needed

[jhb50]

As a test I have loaded the latest CNN.groovy into the console, and set CLASSPATH=C:\Program Files (x86)\Serviio\lib\serviio.jar

When executed I keep getting this error even though org.slf4j.Logger is in the serviio.jar.

I also added serviio.jar to the groovy lib in case it was a classpath problem but still the same problem.

Any ideas?

  Code:

 
(First part of cnn.groovy omitted) 
groovy>         static void main(args) {
groovy>         // this is just to test
groovy>         CNN extractor = new CNN()
groovy>         
groovy>         assert extractor.extractorMatches( new URL("http://rss.cnn.com/rss/edition.rss") )
groovy>         assert !extractor.extractorMatches( new URL("http://google.com/feeds/api/standardfeeds/top_rated?time=today") )
groovy>         
groovy>         Map videoLinks = ['default': new URL('http://edition.cnn.com/video/data/3.0/video/business/2011/11/01/intv-greece-market-reax.cnn/index.xml')]
groovy>         ContentURLContainer result = extractor.extractUrl(videoLinks, PreferredQuality.MEDIUM)
groovy>         println "Result: $result"         
groovy>     }
groovy> }

If CNN.groovy is similar to Youtube.groovy then you'll need to put a couple more jars on your classpath, e.g.

set CLASSPATH=C:\Program Files (x86)\Serviio\lib\serviio.jar;C:\Program Files (x86)\Serviio\lib\slf4j-api.jar;C:\Program Files (x86)\Serviio\lib\slf4j-log4j12.jar;C:\Program Files (x86)\Serviio\lib\log4j.jar;

I can't test the above because I'm not developing in windows. On linux I'm using:

groovy -cp lib/serviio.jar:lib/slf4j-api.jar:lib/slf4j-log4j12.jar:lib/log4j.jar S4c.groovy

this runs the static main method in Youtube.groovy which acts like a unit test. This is useful for development as the rss parsing can be tested without running serviio

Thanks Owen. I tried that and still the same problem. I'll try with the youtube groovy after dinner.


===>> Same problem with youtube.groovy

[jhb50]

Tried running a command like you did. It worked: Here's the output.
I'll try with the console. Thanks

  Code:

C:\Users\John>groovy -cp "C:\Program Files (x86)\Serviio\lib\serviio.jar;C:\Prog
ram Files (x86)\Serviio\lib\slf4j-api.jar;C:\Program Files (x86)\Serviio\lib\slf
4j-log4j12.jar;C:\Program Files (x86)\Serviio\lib\log4j.jar" "C:\Program Files (
x86)\Serviio\plugins\CNN.groovy"

OK, got the groovy console to work by putting all th jars in groovy lib.
I have no idea why CLASSPATH did not work.

I think my original suggestion didn't work because of the spaces in your path. They will mess things up. I should have suggested it with surrounding quotes

set CLASSPATH="C:\Program Files (x86)\Serviio\lib\serviio.jar;C:\Program Files (x86)\Serviio\lib\slf4j-api.jar;C:\Program Files (x86)\Serviio\lib\slf4j-log4j12.jar;C:\Program Files (x86)\Serviio\lib\log4j.jar;"

using an environment (as above) is no longer recommended, I'd stick with the -cp flag

Running same command that worked above with beta 1 and with beta 2 I get this different error, with every groovy... but they all compile fine when loaded in Serviio.

Can anyone help? Is there a new jar dependency?

  Code:

C:\Users\John>groovy -cp "C:\Program Files (x86)\Serviio\lib\serviio.jar;C:\Prog
ram Files (x86)\Serviio\lib\slf4j-api.jar;C:\Program Files (x86)\Serviio\lib\slf
4j-log4j12.jar;C:\Program Files (x86)\Serviio\lib\log4j.jar" "C:\Program Files (

Can anyone help? Is there a new jar dependency?

Not really a new dependency; you need the REST API library : "org.restlet.jar".
About classpath, the simpler is to add everything in the lib directory.
On Windows :

  Code:

@echo off
SETLOCAL enabledelayedexpansion
(...)
set CLASSPATH="."
for %%i in ("%SERVIIO_HOME%\lib\*.jar") do set SERVIIO_CLASSPATH=!SERVIIO_CLASSPATH!;%%i
(...)
groovy -cp "%SERVIIO_CLASSPATH%" XXX


On Unix :

  Code:

#!/bin/sh
(...)
LIB=${SERVIIO_HOME}/lib
SERVIIO_CLASSPATH="."
for jar in `ls -1 ${LIB}/*.jar`; do SERVIIO_CLASSPATH="${SERVIIO_CLASSPATH}:${jar}"; done
(...)
groovy -cp "$SERVIIO_CLASSPATH" XXX
