Problem
As i said in previously post, Tomcat 5.5.25 made a lot of modification in policy file, which may enhance security on web application but it also causing a lot of problem, see another error message :
SEVERE: Context initialization failed java.security.AccessControlException:
access denied (java.lang.RuntimePermission accessDeclaredMembers) at
java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)
Solution
Policy file issue, vi 04webapps.policy, this file is usually located at policy.d folder
mkyong@mkyong-desktop:/etc/tomcat5.5/policy.d$ 04webapps.policy
add following statement into the policy file
permission java.lang.RuntimePermission "accessDeclaredMembers";
For example,
File : 04webapps.policy
// JVM properties to allow read access
permission java.util.PropertyPermission "java.version", "read";
permission java.util.PropertyPermission "java.vendor", "read";
//omitted for readability
// Precompiled JSPs need access to this package.
permission java.lang.RuntimePermission "accessClassInPackage.org.apache.jasper.runtime";
permission java.lang.RuntimePermission "accessClassInPackage.org.apache.jasper.runtime.*";
permission java.lang.RuntimePermission "accessDeclaredMembers";
};
Saved it, restart Tomcat and Done.
I will be created PDF File in Runtime Applet Window (Button Click Event). I face this error:
“java.security.accesscontrolexception access denied (java.lang.runtimepermission getenv.*) in Applet Window”
Code

.
pdfFile = new File(System.getenv(“Temp”) + File.separator + “Filename.pdf”);
if (pdfFile.exists())
{
if (Desktop.isDesktopSupported()) {
Desktop.getDesktop().open(pdfFile);
}
}

Well, it depends, in my case im deploying an application through JWS and i got that message. My app contains a web service client and i needed some jars to connect the server.
The problem was that the jnlp file was missing the section:
Of course, the jars are signed in order to run without problems. Once i added that instructions the exception gone.
Btw, I didn’t need to modify any policy file.
I dont know what happened with the code.
Just add the all-permissions tag inside security tag.
