Java 2 security | HCL Digital Experience
Java 2 (J2SE) security provides a policy-based, fine-grain access control mechanism that increases overall system integrity by checking for permissions before allowing access to certain protected system resources. J2SE security allows you to set up individual policy files that control the privileges assigned to individual code sources. If the code does not have the required permissions and still tries to execute a protected operation, the Java™ Access Controller will throw a corresponding security exception.
Default location and policy file | Protection scope |
---|---|
AppServer_root//java/jre/lib/security/java.policy z/OS® only path: AppServer_root//java/lib/security/java.policy | This is the root policy file that contains permissions for all the processes launched by WebSphere® Application Server. |
wp_profile_root/properties/server.policy | This policy file grants default permissions to all product servers. |
wp_profile_root/properties/client.policy | This policy file grants default permissions for all of the product client containers and applets on a node. |
wp_profile_root/config/cells/cell_name/nodes/node_name/spi.policy | This template is for the Service Provider Interface (SPI) or the third party
resources that are embedded in the product. The default permission is java.security.AllPermissions . |
wp_profile_root/config/cells/cell_name/nodes/node_name/library.policy | This policy grants default permissions (empty) to code contained in the shared library (Java™ library classes) to use in multiple product applications. |
wp_profile_root/config/cells/cell_name/nodes/node_name/app.policy | This policy grants default permissions to all enterprise applications running on this node in this cell. |
wp_profile_root/config/cells/cell_name/applications/ear_file_name/deployments/application_name/META-INF/was.policy | This policy assigns permissions to a specific enterprise application, imbedded within EAR:/META-INF/was.policy. |
rar_filename/META-INF/was.policy.RAR | This file can have a permission specification that is defined in the ra.xml file. The ra.xml file is embedded in the RAR file. |
All code artifacts, installed with the HCL Digital Experience product, run with java.security.AllPermission specified either in the server.policy file for the portal shared libraries or in the individual was.policy files for the individual portlets.
Portlets that are installed on HCL Digital Experience after installation can bring along their own was.policy files defining the allowed interactions of the portlet code with the system resources; see Portlet concepts for additional information.
