I am trying use Struts2 jfreechart plugin - using a Maven project.
In Maven dependencies I am able to see the jfree-chart jar file.
DO I need to use a separate package?
Getting following error:

In the struts.xml you have used the code that requires struts2-jfreechart-plugin-x.x.x.jar to be on classpath. This plugin has struts-plugin.xml where the jfreechart-default package is defined. You need this if your package extends jfreechart-default.

Any help will be appreciated.
There are many details missing however on rereading the issue I suspect you are not following the deprecated syntax <service> correctly by trying to use a current example. Since that syntax has been deprecated for 6+ years, I would advice to move to the more current <flow> definitions.
In case you are unable or unwilling to migrate, you need to define an endpoint outside the service and reference it you could try the following steps:
Ensure that the namespaces at the beginning of the file are correct. The error mentions that doc: is not recognized. Maybe the namespaces are outdated.
Ensure that the dependencies in the pom reference your Mule 3.9.x release and not an older version that may not define doc.
Try moving <smtp:outbound-endpoint> to a separate endpoint definition and reference it from the <pass-through-router> as in your original implementation.
Example:
<service name="tool.muleservice.emailServiceintegration">
<inbound>
<inbound-endpoint ref="tool.endpoint.emailNotification"/>
</inbound>
<outbound>
<pass-through-router>
<outbound-endpoint ref="tool.smtp.endpoint.gmailNotification"/>
</pass-through-router>
</outbound>
</service>
<smtps:endpoint name="tool.smtp.endpoint.gmailNotification"
connector-ref="smtpGmailConnector"
subject="test msg"
address="smtps://#[message.inboundProperties['userName']]:#[message.inboundProperties['password']]#smtp.gmail.com"
responseTimeout="10000" doc:name="Send notification email" >
</smtps:endpoint>
<smtp:gmail-connector name="smtpGmailConnector"
contentType="text/html" fromAddress="iip.claims.test#gmail.com"
replyToAddresses="iip.claims.test#gmail.com" >
<smtp:header key="foo" value="bar" />
<smtp:header key="baz" value="boz" />
</smtp:gmail-connector>
Finally if everything else fails you could try removing the doc:name attribute and see what happens.
i have written a scheduled task which call an Api in sequence in wso2 ei 6.4.0. my task is :
<task xmlns="http://ws.apache.org/ns/synapse"
name="GetMunicipalityAPIToken"
class="org.apache.synapse.startup.tasks.MessageInjector"
group="synapse.simple.quartz">
<trigger interval="60"/>

<property xmlns:task="http://www.wso2.org/products/wso2commons/tasks"
name="injectTo"
value="sequence"/>
</task>
and my sequence is :
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="GetTokenFromMunicipalityService" xmlns="http://ws.apache.org/ns/synapse">
<send>
<endpoint>
<http method="POST" uri-template="http://x.x.x.x/api/MunicipalityBill/connect/token"/>
</endpoint>
</send>
</sequence>
but when i run integrator.bat in wso2eiHome/bin I got this error : "Could not initialize Start up controller. TaskManager not found" and the Api dont be called. Do i forget something ?
The error can be caused when you do not have org.wso2.carbon.mediation.ntask.NTaskTaskManager defined in the server. Could you please check whether the following is added in the synapse.xml file located in the [EI_HOME]/repository/deployment/server/synapse-configs/default/ directory
<definitions xmlns="http://ws.apache.org/ns/synapse">
<taskManager provider="org.wso2.carbon.mediation.ntask.NTaskTaskManager"/>

I try to create small extension for displaying string in Product page Magento 1.9.2. So I did it using "community" code pool for effecting block (block name ="product.info") in catalog.xml layout but it did not work till. I think my code is right but I don't sure whether all relevant folders (Controller, helper, Observer) are included or not in my module(Dinod). Please any one can help me to create this extension by using "community" code pool in Magento 1.9.2.
I failed to get expected output by testing my extension using "community" code pool. But same extension structure work fine after using "core" code pool. So I stored my module(Dinod) inside "app/code/core/Mage" folder and that time worked properly.
This code structure does not generate any expected output through frontend (product page).

Above code structure does not generate any expected output through frontend (product page).

</reference>
</catalog_product_view>
</layout>
But I want to get same output only using "community" code pool instead of using "core" code pool for effecting block (block name ="product.info") in catalog.xml layout.
Your block definition is wrong
<blocks>
<jpdn_dinod>
<class>Jpdn_Dinod_Block_Product_View</class>
</jpdn_dinod>
</blocks>
this is not how you should declare it. Remove product_view
<class>Jpdn_Dinod_Block</class>
this should be enough
I am relative new in wso2 and are having some little problems. I already asked here, how to make this conversion, and was able to do so in another moment. But now i tried to do the same with the code passed for stack overflow:
<?xml version="1.0" encoding="UTF-8"?>

<header action="remove" name="To" scope="default"/>
<property name="RESPONSE" scope="default" type="STRING" value="true"/>
<send/>
</inSequence>
<outSequence/>
<faultSequence/>
</resource>
</api>
And with the send equal request, of what was taught before:
But now i am receiving this error:

I already searched in the internet and in stackoverflow, but none of the resolutions used to this problem, solved in my case.
If anyone could help me i would stay quite grateful.
Thank you everyone.
The API you have shared is working fine. I have tried with postman and advanced rest client.
Refer https://docs.wso2.com/display/EI610/JSON+Support for more information about json support.
I can get the response for your api without error. Try with "application/xml" in the api instead of "text/xml".
<property name="messageType" value="application/xml" scope="axis2" type="STRING"/>
I want to use json with Struts2. However, when I set the action return type to "json", I got "there is no result type defined for type 'json' mapped with name 'success'." Bellow is struts.xml file.
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.custom.i18n.resources" value="resource"/>
<package extends="struts-default" name="test">
<action name="inputHandler" class="inputHandlerAction">
<result name="input">/index.jsp</result>
<result>/result.jsp</result>
</action>
<action name="setLangHandler" class="com.sesoft.test.setLanguageHandler">
<result>/index.jsp</result>
</action>
<action name="Handler" class="com.sesoft.test.Handler">
<result>/test2.jsp</result>
</action>
</package>
<package name="example" extends="json-default">
<action name="ajaxHandler" class="com.sesoft.test.AjaxHandler">
<result name="success" type="json" />
</action>
</package>
</struts>
Before I added the json Action, all other action performs fine. But after I added the json Action, the server failed to action with error code 503.
libs I've added "jsonplugin-0.33.jar" to the lib directory.
You don't have the JSON result defined in your struts.xml package. If you only need default things then you can just extend json-default instead of struts-default. If you need to customise the package then include the following and that should do the trick:
<result-types>
<result-type name="json" class="com.googlecode.jsonplugin.JSONResult"/>
</result-types>
you package should extends json-default
<package name="json-default" extends="struts-default">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult"/>
</result-types>
<interceptors>
<interceptor name="json" class="org.apache.struts2.json.JSONInterceptor"/>
</interceptors>
</package>
If using Maven you may need to add the dependency e.g.
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>2.2.3</version>
</dependency>
Here is my configuration in pom.xml:
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>2.3.1.2</version>
</dependency>
In the action result you only need to specify type="json" :
<result type="json"/>
Remember the variable getter and setter in type="json" response give getters in the action.
Include json-default in the extends parameter:
<package name="default" extends="struts-default,json-default">
<action>
...
...
</action>
</package>
