[seek-dev] config file for ecogrid put service

[Bing Zhu]

Matt,

I was not in yesterday and was not able to reply your mail yesterday.

Good suggestions. The implementation for config file definitely needs more
thoughts.

I am also thinking we need to have separate configuration info for each
service. e.g. one
service needs debug on while the other don't need debug info. But having one
config file
for each service is not desirable. So we can have one config file for
ecogrid, say,
EcogridConfig.xml,  which has config info as of following.

...
<EcogridLeveleOneQueryService>
   <metacatURL>http://indus.nceas.ucsb.edu/knb-oracle/metacat</metacatURL>
   <srbMatHost>orion.sdsc.edu</srbMatHost>
   <debugOn>yes</debugOn>
<EcogridLeveleOneQueryService>

<EcogirdLevelOnePutService>
   <metacatURL>http://indus.nceas.ucsb.edu/knb-oracle/metacat</metacatURL>
   <srbMatHost>orion.sdsc.edu</srbMatHost>
   <srbPort>6617</srbPort>
   <debugOn>no</debugOn>
<EcogirdLevelOnePutService>

...


For the current implementation, I used one globus call,
ContainerConfig.getConfig().getConfigPath() in
the org.globus.ogsa.config.ContainerConfig package, which returns the path
$TOMCAT/webapps/ogsa/WEB-INF.
We can modify it based on your code.

Hi Bing,

I hope that the config path you mentioned does not hard-code "ogsa" as
the context.   If so, you should probably use code like this to avoid
that hard-coding (note that I assume the availability of the
ServletConfig object named "config" below)...

private static final String CONFIG_DIR = "WEB-INF/etc";
                                                              private
static final String CONFIG_NAME = "MetacatConfig.xml";
this.context = config.getServletContext();

String dirPath = context.getRealPath(CONFIG_DIR);
File propertyFile = new File(dirPath, CONFIG_NAME);

Also, Don't you think these configuration files could be combined into a
single configuraiton file for Metacat/SRB/whatever implementation.  Do
the different implementations share properties?  It would be nice if
they did.

Thanks,
Matt
