Mark,
Looks like you are trying to read a config file on your local filesystem. I believe the generator is looking to access the config file through a URL path - meaning that you need to have the file accessible up through a web server. Ken Keiser

    Hello,

    I'm trying to run a simple test of the THREDDS catalog generator,
    and this is what's happening:

[mao@panther THREDDS]$ /usr/java/j2sdk1.4.1_02/bin/java -classpath 
cataloggen-0.6.jar:thredds.jar:jdom-b8.jar:dods.1.1.1.jar 
thredds.cataloggen.CatalogGen mytest.xml
Catalog NOT read successfully (mytest.xml):
Message=----Catalog Validation version 0.6.02
** InvCatalogFactory.readXML (1) MalformedURLException on URL <mytest.xml> no 
protocol: mytest.xml

Exception in thread "main" java.lang.NullPointerException

thredds.cataloggen.CatalogGen.findCatGenConfigMdata(CatalogGen.java:117)
       at thredds.cataloggen.CatalogGen.<init>(CatalogGen.java:54)
       at thredds.cataloggen.CatalogGen.main(CatalogGen.java:140)
[mao@panther THREDDS]$ cat mytest.xml

       </datasetSource>
     </catalogGenConfig>
   </metadata>
 </dataset>
</catalog>
[mao@panther THREDDS]$

    Any idea why I'm getting the MalformedURLException?

    Thanks,

    Mark


i think you can use file:///path

best to use absolute path if you can
