Any kind of help is appreciated. Thank you!

The main error is:
Caused by: Action class [helloWorldAction] not found - action - bundle://2.0:1/struts.xml:9:64 at
struts.xml from the demo bundle contains wron definitions for action class:
<action name="hello-velocity" class="helloWorldAction">
<result type="velocity">/content/osgi/hello.vm</result>
</action>
<action name="hello-freemarker" class="helloWorldAction">
<result type="freemarker">/content/osgi/hello.ftl</result>
</action>
Try to change the fragment of struts.xml to
<action name="hello-velocity" class="actions.osgi.HelloWorldAction">
<result type="velocity">/content/osgi/hello.vm</result>
</action>
<action name="hello-freemarker" class="actions.osgi.HelloWorldAction">
<result type="freemarker">/content/osgi/hello.ftl</result>

How to fix this?

You have different filter name in filter and mapping tags as below:
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
Change the filter-name in mapping as
<filter-name>struts</filter-name>
So it matches with filter-name defined within filter.

You're missing the OGNL library.

Firstly, you need to change your struts.xml file.
Change it to this:
<action name="getTutorial" class="org.prem.javabrain.action.TutorialAction">
<result name="success">/success.jsp</result>
<result name="failure">/error.jsp</result>
</action>
Secondly, you need to check if all the libraries i.e. jars especially the ognl jar are in your class path. Possibly, you can post the list of jars you have in your class path.

The struts.xml file is incorrect. The result tags should be inside the action tags.
I would suggest you use the DTD definitions in your xml files which will help in checking the grammar of your XML files. Add this line after the first line of your struts.xml file:
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
This DTD will help the IDE to suggest you the correct XML grammar while you are developing.
So the final struts.xml file would look somewhat like this:
<?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>
<package name="default" extends="struts-default">
<action>name="getTutorial" class="org.prem.javabrain.action.TutorialAction">
<result name="success">/success.jsp</result>
<result name="failure">/error.jsp</result>
</action>
</package>
</struts>
Hope this helps :)

Struts2 Configuration file name in web.xml

http://struts.apache.org/2.3.1.2/docs/webxml.html
According to above link we can specify configuration file name in web.xml. so I have added config param in following mapping.
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
<init-param>
<param-name>config</param-name>
<param-value>struts.xml</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
Now I am unable to start web application. Following log is printed on console.

You need to define struts-default.xml and struts-plugin.xml as well inside <init-param>.
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,struts-plugin.xml,struts.xml</param-value>
</init-param>
Without it Struts2 cannot find necessary beans/results/interceptors/etc. defined in struts-default.xml file. Of course you could copy all declarations from default file to your configuration file.

Add doctype declaration to your struts.xml file.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
...
</struts>

Add the library "commons-lang3-3.X", then it will work fine.

Regards,
nag kamma.

hey guys ensure that if you put all struts2 jars in lib directory. else in case if add all jars as a user library, then goto project properties and in the deployment assembly click add and select java build path entries and select your user library(i.e.) struts2 library.
