Struts + GAE java.security.AccessControlException: access denied of struts2-core-2.3.15.3.jar
google-app-engine, java, struts2
Solution
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:
- The struts-plugin.xml file specifies that the FileManager and FileManagerFactory implementation from the plugin should be taken as the default
- Struts2FileManagerFactoryOnGAE, custom implemention of the FileManagerFactory interface where the only change from the DefaultFileManagerFactory implementation is the class name
- 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.
Problem
I am using struts in GAE. I am using GAE 1.8 and struts 2.3.15 jar file. In my application i am facing this exception ``` java.security.AccessControlException: access denied ("java.io.FilePermission"
