public interface Server_properties
server.properties fileserver.properties file is a configuration file read by the Smart GWT server -
 see the file itself for more information and default or sample settings.  Note that this is a standard Java Properties file, except it allows variable substitution from other properties defined earlier in the file.
 It's loaded from the CLASSPATH, so it can be
 anywhere in the  CLASSPATH, but is typically either in the projects java "src"
 directory or in WEB-INF/classes. 
 Server side code can access and modify the
 properties specified in this file via the com.isomorphic.base.Config class. 
 When modifying server.properties developers should restart the servlet engine
 after changing this file to pick up changes. 
 The following settings are used by Smart GWT
 server features.
 Note that this is not intended to be an exhaustive list: 
project.datasources specifies the location for      server-backed DataSource configuration files
 (*.ds.xml files)     as well as server-backed SimpleType declarations (*.type.xml files) project.ui specifies the location for      XML Screen definitions (*.ui.xml
 files)project.project specifies the location for      XML Project definitions (*.project.xml
 files)project.apps specifies the location for      Application declarations (*.app.xml
 files)modulesDir specifies the location for modules files if using
 the     loadISC or loadModules jsp tags.isc.addVersionToLoadTags (boolean) May be set to false to disable the     
 automatic versioning applied to URLs written out by      loadISC or loadModules jsp tags.isc.defaultVersionStyle specifies
 the default versionStyle     for loadISC or loadModules jsp tags.     Default value is "params".isc.versionPathSegmentPrefix Specifies a standard path segment prefix written
 out     by loadISC or loadModules jsp tags     with
 versionStyle set to "pathSegment". The generated path segment will      consist of
 this prefix combined with the current Smart GWT version.     The default value is
 "isc_version.".isc.stripVersionPathSegments (boolean) When
 set to true, any URL containing     a path segment that starts with the
 isc.pathSegmentPrefix will be automatically     stripped by the Smart GWT
 FileDownloadServlet, or the dedicated VersionedURLFilter      when resolving the URL to a
 resource on the filesystem.authentication.defaultRequired can be
 used to require     authentication for all dataSources by defaultauthentication.superuserRole can be used to identify a      user role as the super user
 role.DataBase
 configuration settings for SQL DataSources.     Note that the Admin Console tool provides an interface      for adding
 database configuration blocks to server.properties without the need to      edit the file by
 hand.SQL
 Connection pooling settings     for SQL DataSources.JpaIntegrationOperationBinding.mail feature.optional
 RealTimeMessaging module.enabledBuiltins can be used to configure
 access to methods provided     by the server side BuiltInRPC class. (See server
 side JavaDoc for that     class as well as the tools deployment overview for more      information).domainSync.disabled and domainSync.baseDomains can be used to    
 configure domain synching behavior.import.consume.bom can be set to false to switch off automatic consumption    
 of Byte Order Markers when importing UTF data (see the server Javadocs for the DataImport     
 class for more details)datasources.autoConvertRelativeDates can be used
 to change when relative dates     are converted or to entirely disable the automatic conversion
 (see DataSource.autoConvertRelativeDates for more details)reflection.classCache specifies how (if enabled) Smartclient Reflection
 library caches loaded classes,      availables values are "global", "classloader" (default),
 "jdk" and "off". See comment in server.properties for more      details.sql.log.formatQueries can be set to true to enable the SQL
 queries formatting      in server logs under
 com.isomorphic.sql.SQLDriver categorysql.log.compactFormatting can be set to true to make formatted
 SQL queries more compactsql.log.maxLength can be set to an integer
 controlling the maximum length of formatted SQL queriessql.log.queriesSlowerThan can be set to an integer controlling SQL query
 execution time threshold in       milliseconds, which if exceeded query is identified as "slow"
 and may be logged under specific logging category. See       DataSource.logSlowSQL for more
 details.sql_comment_mdc_key if specified is used as a logging MDC key to
 get the configurable "log_correlation_id"     third party tools, like Dynatrace, Graylog etc.,
 use for the context. Smartclient picks that from the logging MDC and     adds as a comment to
 the end of generated SQL queries, so those can be connected to the context.
