### struts default properties
###(can be overridden by a struts.properties file in the root of the classpath)
###
### specifies the configuration used to configure struts
### one could extend org.apache.struts2.config.configuration
### to build one's customize way of getting the configurations parameters into struts
# struts.configuration=org.apache.struts2.config.defaultconfiguration
### this can be used to set your default locale and encoding scheme
# struts.locale=en_us
struts.i18n.encoding=utf-8
### if specified, the default object factory can be overridden here
### note: short-hand notation is supported in some cases, such as "spring"
### alternatively, you can provide a com.opensymphony.xwork2.objectfactory subclass name here
struts.objectfactory = spring
### specifies the autowiring logic when using the springobjectfactory.
### valid values are: name, type, auto, and constructor (name is the default)
struts.objectfactory.spring.autowire = name
### indicates to the struts-spring integration if class instances should be cached
### this should, until a future spring release makes it possible, be left as true
### unless you know exactly what you are doing!
### valid values are: true, false (true is the default)
struts.objectfactory.spring.useclasscache = true
### if specified, the default object type determiner can be overridden here
### note: short-hand notation is supported in some cases, such as "tiger" or "notiger"
### alternatively, you can provide a com.opensymphony.xwork2.util.objecttypedeterminer implementation name here
### note: by default, com.opensymphony.xwork2.util.defaultobjecttypedeterminer is used which handles type detection
### using generics. com.opensymphony.xwork2.util.genericsobjecttypedeterminer was deprecated since xwork 2, it's
### functions are integrated in defaultobjecttypedeterminer now.
### to disable tiger support use the "notiger" property value here.
#struts.objecttypedeterminer = tiger
#struts.objecttypedeterminer = notiger
### parser to handle http post requests, encoded using the mime-type multipart/form-data
# struts.multipart.parser=cos
# struts.multipart.parser=pell
struts.multipart.parser=jakarta
# uses javax.servlet.context.tempdir by default
struts.multipart.savedir=
struts.multipart.maxsize=2097152
### load custom property files (does not override struts.properties!)
# struts.custom.properties=application,org/apache/struts2/extension/custom
### how request urls are mapped to and from actions
#struts.mapper.class=org.apache.struts2.dispatcher.mapper.defaultactionmapper
### used by the defaultactionmapper
### you may provide a comma separated list, e.g. struts.action.extension=action,jnlp,do
#struts.action.extension=do
struts.action.extension = action,do,
### used by filterdispatcher
### if true then struts serves static content from inside its jar.
### if false then the static content must be available at
struts.serve.static=true
### used by filterdispatcher
### this is good for development where one wants changes to the static content be
### fetch on each request.
### note: this will only have effect if struts.serve.static=true
### if true -> struts will write out header for static contents such that they will
### be cached by web browsers (using date, cache-content, pragma, expires)
### headers).
### if false -> struts will write out header for static contents such that they are
### not to be cached by web browser (using cache-content, pragma, expires
### headers)
struts.serve.static.browsercache=true
### set this to false if you wish to disable implicit dynamic method invocation
### via the url request. this includes urls like foo!bar.action, as well as params
### like method:bar (but not action:foo).
### an alternative to implicit dynamic method invocation is to use wildcard
### mappings, such as
struts.enable.dynamicmethodinvocation = true
### set this to true if you wish to allow slashes in your action names. if false,
### actions names cannot have slashes, and will be accessible via any directory
### prefix. this is the traditional behavior expected of webwork applications.
### setting to true is useful when you want to use wildcards and store values
### in the url, to be extracted by wildcard patterns, such as
###
### "/foo/save".
struts.enable.slashesinactionnames = false
### use alternative syntax that requires %{} in most places
### to evaluate expressions for string attributes for tags
struts.tag.altsyntax=true
### when set to true, struts will act much more friendly for developers. this
### includes:
### - struts.i18n.reload = true
### - struts.configuration.xml.reload = true
### - raising various debug or ignorable problems to errors
### for example: normally a request to foo.action?someunknownfield=true should
### be ignored (given that any value can come from the web and it
### should not be trusted). however, during development, it may be
### useful to know when these errors are happening and be told of
### them right away.
struts.devmode = false
### when set to true, resource bundles will be reloaded on _every_ request.
### this is good during development, but should never be used in production
struts.i18n.reload=false
### standard ui theme
### change this to reflect which path should be used for jsp control tag templates by default
struts.ui.theme=simple
struts.ui.templatedir=template
#sets the default template type. either ftl, vm, or jsp
struts.ui.templatesuffix=ftl
### configuration reloading
### this will cause the configuration to reload struts.xml when it is changed
struts.configuration.xml.reload=false
### location of velocity.properties file. defaults to velocity.properties
struts.velocity.configfile = velocity.properties
### comma separated list of velocitycontext classnames to chain to the strutsvelocitycontext
struts.velocity.contexts =
### location of the velocity toolbox
struts.velocity.toolboxlocation=
### used to build urls, such as the urltag
struts.url.http.port = 80
struts.url.https.port = 443
### possible values are: none, get or all
struts.url.includeparams = get
### load custom default resource bundles
struts.custom.i18n.resources=com.myshop.resources.applicationresources
### workaround for some app servers that don't handle httpservletrequest.getparametermap()
### often used for weblogic, orion, and oc4j
struts.dispatcher.parametersworkaround = false
### configure the freemarker manager class to be used
### allows user to plug-in customised freemarker manager if necessary
### must extends off org.apache.struts2.views.freemarker.freemarkermanager
#struts.freemarker.manager.classname=org.apache.struts2.views.freemarker.freemarkermanager
### enables caching of freemarker templates
### has the same effect as copying the templates under web_app/templates
struts.freemarker.templatescache=false
### enables caching of models on the beanwrapper
struts.freemarker.beanwrappercache=false
### see the strutsbeanwrapper javadocs for more information
struts.freemarker.wrapper.altmap=true
### configure the xsltresult class to use stylesheet caching.
### set to true for developers and false for production.
struts.xslt.nocache=false
### a list of configuration files automatically loaded by struts
struts.configuration.files=struts-default.xml,struts-plugin.xml,struts.xml
### whether to always select the namespace to be everything before the last slash or not
struts.mapper.alwaysselectfullnamespace=false
