Error while trying to run struts2-blank-2.1.8.1 sample application in Eclipse and Tomcat 6

[p karnam]

Hi,

I am trying to run a sample struts2-blank-2.1.8.1 (by unzipping into Tomcat webapps directory) application using Eclipse and Tomcat 6. I am getting the following error not sure what is the issue. I am able to start and stop Tomcat 6 successfully if I remove this sample application from Tomcat Webapps directory. Can anyone let me know what is going on here, is it some incompatibility in versions?

[David Newton]

Did you modify the deployment in any way?

[p karnam]

No, I didn't modify the deployment.

[David Newton]

What libraries does it deploy? Can you post the config (I don't have the latest blank app in front of me)?

[p karnam]

Following are the files in the lib directory of blank application

xwork-core-2.1.6.jar
ognl-2.7.3.jar
freemarker-2.3.15.jar
commons-io-1.3.2.jar
commons-fileupload-1.2.1.jar

please note that I have removed struts2-core-2.1.8.1.jar for Prj lib dir, as the server was complaining about duplication in project lib and Tomcat lib directories.

Please let me know if any other info required.

[David Newton]

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is very difficult to read. You can edit your post to include them by using the button.

Remove the shared Struts 2 lib; only deploy it in your project.

What's in example.xml? It shouldn't be complaining about missing Spring stuff from what I see so far.

[p karnam]

Tried moving the Struts 2 to project library from shared lib, but now getting error similar to following. Moving Struts 2 core file to project dir from common/share directory of Tomcat doesn't make sense to me, ideally the common jars should be in shared drive and project specific should be in project directory, correct me if I am wrong?

Caused by: Unable to load bean: type:com.opensymphony.xwork2.ObjectFactory class:org.apache.struts2.osgi.DelegatingObjectFactory - bean - jar:file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat%206.0/lib/struts2-osgi-plugin-2.1.8.1.jar!/struts-plugin.xml:18:126

Yes, this is Struts application not a Spring application, not sure why it is complaining about spring?

Following is example.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">

        </action>

        <action name="Login_*" method="{1}" class="example.Login">
            <result name="input">/example/Login.jsp</result>
            <result type="redirectAction">Menu</result>
        </action>

        <action name="*" class="example.ExampleSupport">
            <result>/example/{1}.jsp</result>
        </action>

        <!-- Add actions here -->
    </package>
</struts>

[David Newton]

Because you've deployed a random collection of Struts 2 libraries in the Tomcat lib directory. Remove them. The exception says exactly what's wrong:

jar:file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat%206.0/lib/struts2-osgi-plugin-2.1.8.1.jar!/struts-plugin.xml:18:126

You can't just deploy any old Struts 2 plugin you want: plugins introduce their own dependencies and configuration requirements.

[p karnam]

Thank you David. I have removed all the plugins from Tomcat lib directory, now the application is working fine. I appreciate your help in resolving this.

[roshan we]

As I see this is not a spring application, but if it was and if it gives this error add the following jar file to your lib to solve the problem: struts2-spring-plugin.jar

[David Newton]

Late, and wrong. You'd also need to add all of Spring's dependencies. Please try to make sure the information you're adding is timely and appropriate.
