[jira] Resolved: (WW-3063) Codebehind plugin fails to locate
SayHelloAction class
[ https://issues.apache.org/struts/browse/WW-3063?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Musachy Barroso resolved WW-3063.
---------------------------------
Resolution: Incomplete
Please ask on the mailing list, this is likely to be a configuration problem. your action should be mapped to /all/say-hello

> ### START SNIPPET: complete_file
> ### 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
> ### ensures the autowire strategy is always respected.
> ### valid values are: true, false (false is the default)
> struts.objectFactory.spring.autoWire.alwaysRespect = false
> ### 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
> ### The blank extension allows you to match directory listings as well as pure action names
> ### without interfering with static resources.
> struts.action.extension=action,,
> ### Used by FilterDispatcher
> ### If true then Struts serves static content from inside its jar.
> ### If false then the static content must be available at <context_path>/struts
> 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 <action name="*/*" method="{2}" class="actions.{1}">
> 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
> ### <action name="*/*" method="{2}" class="actions.{1}"> to match "/foo/edit" or
> ### "/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=xhtml
> 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 = none
> ### Load custom default resource bundles
> # struts.custom.i18n.resources=testmessages,testmessages2
> ### 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
> ### maxStrongSize for MruCacheStorage for freemarker
> struts.freemarker.mru.max.strong.size=100
> ### configure the XSLTResult class to use stylesheet caching.
> ### Set to true for developers and false for production.
> struts.xslt.nocache=false
> ### Whether to always select the namespace to be everything before the last slash or not
> struts.mapper.alwaysSelectFullNamespace=false
> ### Whether to allow static method access in OGNL expressions or not
> struts.ognl.allowStaticMethodAccess=false
