When an error event occurs I am chaining the result to an error action, this works okay when its all happening in the same namespace but when chaining across namespaces the results of the chained action are in the chaining actions namespace.
<package name="mynamespace-htm" namespace="/mynamespace/htm" extends="mybase-base">
<action name="newsItem" class="com.mypackage.control.GetNewsItemAction">
<result name="success">newsItem.jsp</result>
<result name="error" type="chain">
<param name="actionName">invalidSite</param>
<param name="namespace">/mynamespace</param>
</result>
</action>
</package>
<package name="mynamespace" namespace="/mynamespace" extends="mybase-base">
<action name="invalidSite" class="com.mypackage.control.GetInvalidSiteAction">
<result name="success">commonviews/invalidSite.jsp</result>
</action>
</package>
If I access the newsItem action in a way that causes an error result I get an exception javax.servlet.ServletException: File "/mynamespace/htm/commonviews/invalidSite.jsp" not found why is it trying to find the file relative to the original namespace mynamespace/htm instead of mynamespace?

Prevent same action called twice as long as user is in current session

Closed 5 years ago.
I'm trying to avoid double-submit problems using tokenSession. My action methods are working fine without tokenSession technique.
I add <s:token/> in upsert_crypto_sources.jsp and tokenSession interceptor in struts.xml but I receive request as null in my action excludedMethod of list().
The list page doesn't need to avoid double submit problem but if I add <s:token/> in view_crypto_sources_list.jsp and remove list() from excludedMethod then I always receive result invalid.token.
My struts.xml is like:
<struts>
<package name="key-manager" namespace="/shared/km" extends="console-default" strict-method-invocation="true">
<action name="manage_cs_*" method="{1}" class="console.shared.km.ASC_ManageCryptoProfilesAction">
<interceptor-ref name="tokenSession">
<param name="excludeMethods">
list, initInsert, load, delete
</param>
</interceptor-ref>
<result name="list">/shared/km/view_crypto_sources_list.jsp</result>
<result name="insert">/shared/km/upsert_crypto_sources.jsp</result>
<result name="update">/shared/km/upsert_crypto_sources.jsp</result>
<result name="load">/shared/km/upsert_crypto_sources.jsp</result>
<allowed-methods>list, insert, load, update, delete, testConnection, forward, cancel</allowed-methods>
</action>
My action implements ServletRequestAware interface therefore it gets the request member variable set using setServletRequest() method.
I added a defaultStack interceptor and it is working fine:
<struts>
<package name="key-manager" namespace="/shared/km" extends="console-default" strict-method-invocation="true">
<action name="manage_cs_*" method="{1}" class="console.shared.km.ASC_ManageCryptoProfilesAction">
<interceptor-ref name="defaultStack"></interceptor-ref>
<interceptor-ref name="tokenSession">
<param name="excludeMethods">
list, initInsert, load, delete
</param>
</interceptor-ref>
<result name="list">/shared/km/view_crypto_sources_list.jsp</result>
<result name="insert">/shared/km/upsert_crypto_sources.jsp</result>
<result name="update">/shared/km/upsert_crypto_sources.jsp</result>
<result name="load">/shared/km/upsert_crypto_sources.jsp</result>
<allowed-methods>list, insert, load, update, delete, testConnection, forward, cancel</allowed-methods>
</action>
In Struts1 you can use the attribute parameter from element(struts-config.xml) and access it's value within the action class via the actionMapping.getParameter() method. For actions requiring multiple steps, the parameter is often used to indicate which step the mapping is associated
with.
Ex:
<action path="\something\Step1"
type="actions.SomethingAction"
parameter="step1"> ...
<action path="\something\Step2"
type="actions.SomethingAction"
parameter="step2"> ...
Which is the alternative solution for Struts2?
Parameters in the action configuration could be used instead
<package name="something" namespace="/something" extends="struts-default">
<action name="Step1" class="actions.SomethingAction">
<param name="step1" ...
</action>
<action name="Step2" class="actions.SomethingAction">
<param name="step2" ...
</action>
</package>
<action name="AddedPaid" class="iland.payment.SupplierPaidAction" method="insert">
<result name="success" type="redirect">ShowPaid</result>
<result name="input">/pages/payment/addToPay.jsp</result>
<result name="login">/pages/login.jsp</result>
</action>
<action name="ShowPaid" class="iland.payment.SupplierPaidAction" method="fetchAllByfk">
<result name="success">/pages/paid/showPaidDetails.jsp</result>
<result name="input">/pages/payment/ShowPay.jsp</result>
<result name="login">/pages/login.jsp</result>
</action>
Here AddedPaid Action is used to add form data in to database.
After adding data in to database I am redirecting result to ShowPaid action.
This is working properly.
Now I want whenever I redirect AddedPaid action to ShowPaid.
ShowPaid must show data of perticular supplierPaymentId for which I have added data in AddedPaid.
After redirect it is howing url
http://localhost:8082/ClothStore/ShowPaid
I want
http://localhost:8082/ClothStore/ShowPaid?supplierPaymentId=4
It's strange, usually people have 2 and want 1 :)
Btw, since you are using PostRedirectGet, you need to manually pass the parameter in Struts configuration.
Assuming you have a variable named supplierPaymentId with getter and setter, it's achievable like follows:
<action name="AddedPaid" class="iland.payment.SupplierPaidAction" method="insert">
<result name="success" type="redirectAction">
<param name="actionName">ShowPaid</param>
<param name="supplierPaymentId">${supplierPaymentId}</param>
</result>
<result name="input">/pages/payment/addToPay.jsp</result>
<result name="login">/pages/login.jsp</result>
</action>
Also use redirectAction instead of redirect, that is meant to be used to redirect to external URLs or non-Action URLs
First of all use redirectAction result instead of redirect to redirect to another action.
And use param tag to add parameters in your result configuration.
<result type="redirectAction">
<param name="actionName">ShowPaid</param>
<param name="supplierPaymentId">${supplierPaymentId}</param>
</result>
Note you need to have getter/setter for supplierPaymentId in your action class.
I am using Struts 2 + Hibernate (full-hibernate-plugin-for-struts2), and I have this code to check if image to upload is png:
struts.xml
<struts>
<package name="mypack" namespace="/" extends="hibernate-default">
...
<action name="myaction" class="com.actions.MyAction" >
<interceptor-ref name="defaultStackHibernate">
<param name="fileUpload.allowedTypes">image/png</param>
</interceptor-ref>
<result name="success" type="tiles" >baseLayout</result>
<result name="error" type="tiles" >error</result>
<result name="input" type="tiles" >baseLayout</result>
</action>
...
</package>
</struts>
The error message that comes out if I upload not allowed image types is:
Content-Type not allowed: image "img.jpg" "upload__2988a871_13b93535e21__7fc1_00000009.tmp" image/jpeg
How can I modify that error message? Using something like "hibernate-messages.properties"?
You can override this message by creating text for this key:
struts.messages.error.content.type.not.allowed
Firstly, I went here ( http://code.google.com/p/struts2-examples/downloads/list and I downloaded Hello_World_Struts2_Mvn.zip) and I run that example.
After that, I went here (http://struts.apache.org/2.x/docs/jfreechart-plugin.html), I add the dependencies for commons-lang-2.5.jar, jcommon-1.0.16.jar and jfreechart-1.0.13.jar and I modify the example downloaded from code.google.com to see how JFreeChart is working, but I receive this error:
Unable to load configuration. - action - file:/C:/.../untitled_war_exploded/WEB-INF/classes/struts.xml:34:67
Caused by: Error building results for action createChart in namespace - action - file:/C:/.../out/artifacts/untitled_war_exploded/WEB-INF/classes/struts.xml:34:67
Caused by: There is no result type defined for type 'chart' mapped with name 'success'. Did you mean 'chart'? - result - file:/C:/.../out/artifacts/untitled_war_exploded/WEB-INF/classes/struts.xml:36:49
At the line 36 in struts.xml is the this code (the code from struts2 website):
<action name="viewModerationChart" class="myapp.actions.ViewModerationChartAction">
<result name="success" type="chart">
<param name="width">400</param>
<param name="height">300</param>
</result>
</action>
What I'm doing wrong?
You need to define Action mappings related to chart differently in Struts.xml.Change your project's struts.xml with Jfreechart related actions and define it in separate package.
For eg.
<package name="struts2" extends="jfreechart-default">
<action name="viewModerationChart" class="myapp.actions.ViewModerationChartAction">
<result name="success" type="chart">
<param name="width">400</param>
<param name="height">300</param>
</result>
</action>
</package>
