Standard Java uses policy files to determine what foreign code is allowed to do. This policy is installed when the application starts, so it is a static policy mechanism. In Jini 2.0, when a service is discovered, it may wish to ask for a policy to be applied at that time, dynamically. Extensions to the basic security model in JDK 1.4 allow this to occur, by permitting dynamic policy setting on class loaders. To allow dynamic policy granting, the Java runtime must have the appropriate classes installed and trusted. This is the purpose of the jsk-policy.jar file from the Jini library. As part of the installation process for Jini, it is recommended that you install this file into the jre/lib/ ext directory of your Java distribution to allow the Java runtime to pick these up as trusted classes when it starts.

The runtime needs to be told about these classes, which you can do by using the runtime define: -Djava.security.properties=security.properties where security.properties is a file containing the single line saying which Jini class to use for dynamic policies. policy.provider=net.jini.security.policy.DynamicPolicyProvider For the client, an array of permissions specifies the permissions the client will grant to a proxy. This array is set in the BasicProxyPreparer. The server can set a permission in the BasicILFactory. This permission is used to perform server-side access control on incoming remote calls.

Ensuring security on the network is a complex task, and the Jini possibilities of mobile code increase the security risks. This chapter presented an end-programmer s view of the new Jini 2.0 security. The architecture behind the Jini security model is highly configurable, and we ve looked at one set of plug-ins to make it (relatively) easy for you as a programmer. However, if you want more control over any part of this process, be aware that you can dig further into this architecture and roll your own for almost all parts of it.

ransactions are a necessary part of many distributed operations. Frequently, two or more objects will need to synchronize changes of state so that they all occur or none occur. This happens in situations such as control of ownership, where one party has to give up ownership at the same time as another asserts ownership. What has to be avoided is only one party performing the action, which could result in either no owners or two owners. In this chapter, we ll examine the Jini transaction manager and show how this can be used to give transaction processing in Jini.

Two-Phase Commit Protocol
The theory of transactions often refers to the ACID properties: Atomicity: All the operations of a transaction must take place, or none of them do. Consistency: The completion of a transaction must leave the participants in a consistent state (whatever that means). For example, the number of owners of a resource must remain at one. Isolation: The activities of one transaction must not affect any other transactions. Durability: The results of a transaction must be persistent. The practice of transactions, however, is that they use the two-phase commit protocol. This requires that participants in a transaction be asked to vote on a transaction. If all agree to go ahead, then the transaction commits, which is binding on all the participants. If any participants abort the transaction during this voting stage, then it forces abortion of the transaction on all participants. Jini has adopted the syntax of the two-phase commit method. It is up to the clients and services within a transaction to observe the ACID properties if they desire. Jini essentially supplies the mechanism of two-phase commit and leaves the policy of meaning to the participants in a transaction.
