PHP – Fatal error: Call to undefined function curl_init()
On current versions of Debian and Ubuntu, you can likely solve this by installing the Curl extension for PHP, and restarting the webserver.
sudo apt-get install php5-curl
It’s possible you’ll need to install more:
sudo apt-get install curl libcurl3 libcurl3-dev;

How to setting “Custom Naming Strategy” in grails project
By default Grails uses Hibernate’s ImprovedNamingStrategy to convert domain class Class and field names to SQL table and column names by converting from camel-cased Strings to ones that use underscores as word separators. You can customize these on a per-class basis in the mapping closure but if there’s a consistent pattern you can specify a different NamingStrategy class to use.
Configure the class name to be used in grails-app/conf/DataSource.groovy in the hibernate section, e.g.
hibernate
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
naming_strategy = com.a5go.CustomNamingStrategy
You can use an existing class or write your own, for example one that prefixes table names and column names:
package com.a5go
import org.hibernate.cfg.ImprovedNamingStrategy
import org.hibernate.util.StringHelper
class CustomNamingStrategy extends ImprovedNamingStrategy
String classToTableName(String className)
"T_" + StringHelper.unqualify(className)

buf.append( s + "\r\n" );
process.waitFor();
System.out.println( buf );
