RE: Is Java_SPLPolicyRuleProvider thread safe?
Hi Naidu,
Thanks for the reply.
So, at this time I put JSPL calls in a synchronized block. Please let me
know when you make it thread safe.
Thanks
Reza

Hi
Java_SPLPolicyRuleProvider is not thread safe.Yes, it is good practice to
have only one instance of it rather than having multiple objects(which can
result to performance related problems).We can have synchronized block for
its methods such that they can be thread safe.

Please respond to Subject
imperius-user@inc Is Java_SPLPolicyRuleProvider
ubator.apache.org thread safe?
Hi,
Is the instance of Java_SPLPolicyRuleProvider thread safe? I mean, if we
have only one instance of this class, can we use it safely in different
threads for creating or executing policies?
Is it a good practice to have only one instance? or it's better to have
several instances in a multi-threaded program (one per thread), or having
one instance in the program and use synchronize block for its method calls.
Thanks,
Reza
