I did lot of search some says remove this property value from sturts.xml file

<constant name="struts.devMode" value="true" />

Some says change the value from true to false. I did it but it didn't work. Please give a solution. I also change the jar file and use 2.1.8 version but in this i got the exception at startup of server which is

java.lang.NoSuchMethodError: com.opensymphony.xwork2.config.ConfigurationManager.addConfigurationProvider(Lcom/opensymphony/xwork2/config/ConfigurationProvider;)V

I am also using following jar files with struts jar file

ognl-3.0.6.jar
sitemesh-2.4.2.jar
struts2-sitemesh-plugin-2.2.3.1.jar
xwork-core-2.3.15.3.jar

please guide me.

Answer 1

From my investigation the

java.security.AccessControlException: access denied ("java.io.FilePermission" "jar:file:\E:\eclipse\Shaun\Convergent\war\WEB-INF\lib\struts2-core-2.3.15.3.jar" "read")

exception only occurs when trying to run a Struts 2 application on Google App Engine for Windows.

I've encountered the same problem on Windows while trying to port an application to GAE, but I couldn't reproduce it under GNU/Linux nor when deployed to Google servers with appcfg.sh --oauth2 update dist/myapp

In order to solve this problem when running under Google App Engine for Windows the only working solution I found was to implement a custom plugin / extension point that implements the following interfaces com.opensymphony.xwork2.FileManager and com.opensymphony.xwork2.FileManagerFactory

The classes which implement the above interfaces inside the plugin override the implementations that Struts 2 instantiates by default, i.e. DefaultFileManager and DefaultFileManagerFactory

The custom file plugin I've created has three main components:

1. The struts-plugin.xml file specifies that the FileManager and FileManagerFactory implementation from the plugin should be taken as the default
2. Struts2FileManagerFactoryOnGAE, custom implemention of the FileManagerFactory interface where the only change from the DefaultFileManagerFactory implementation is the class name
3. Struts2FileManagerOnGAE, custom FileManager implementation, where I've made the essential changes, that is, fileNeedsReloading() methods and internal should return false, and support() method should return true.

Also, inside the WEB-INF/web.xml of the application I've added: <init-param> <param-name>config</param-name> <param-value>struts-default.xml,struts-plugin.xml,struts.xml</param-value> </init-param>

Because I use Ant as a build system, I've created new targets for the custom file plugin, that compile & copy the jar of the plugin to the final artifact: https://gitlab.com/alibitek-java/Struts-GAE/blob/master/build.xml

You can see the source code for my test application at: https://gitlab.com/alibitek-java/Struts-GAE/tree/master

and if you want to give it a try you can just run:

ant dev_appserver

after setting the path to your Google App Engine SDK inside build.xml or you can see it live here http://struts-gae.appspot.com/jsp/index.jsp

What the application does is: you need to guess the random number that was generated, and after a few tries it will show you a hint, and when you guess the number it will show you in how many tries you've guessed it.

Open the <JRE location>\lib\security\java.policy file, then add the permission you need inside a grant entry :

 permission java.io.FilePermission "E:/eclipse/Shaun/Convergent/-" , "read"
