A thread-safe JSP/servlet is one that works correctly when more than one thread is running at the same time. To make your JSPs thread-safe, you can implement the SingleThreadModel interface that prevents two threads from accessing the service method at the same time.

It is well known that static methods with immutable objects as parameters are thread safe and mutable objects are not. ... It maintains no state and operates only on its arguments. I would strongly recommend you read Java Concurrency in Practice, or a similar book dedicated to thread safety in Java.

A std::shared_ptr consists of a control block and its resource. Yes, the control block is thread-safe; but no, the access to the resource is not thread-safe. That means, modifying the reference counter is an atomic operation and you have the guarantee that the resource will be deleted exactly once.

Java java. net. Socket is not actually thread safe: Open the Socket source, and look at the (let say) connected member field and how it is used. You will see that is not volatile , read and updated without synchrinization.

JSP is the view in MVC approach for showing output. Servlet is faster than JSP. JSP is slower than Servlet because the first step in JSP lifecycle is the translation of JSP to java code and then compile. Servlet can accept all protocol requests.

In general no. If the Spliterator used has the CONCURRENT characteristic, then the stream is thread-safe. The stream API defines numerous contracts for each step of the pipeline, if any of them are violated then unpredictable behavior or exception may happen.

2 Answers. UUID is immutable so it's potentially thread safe, but apparently there was some evil caching going on in some accessors that made it unsafe (that bug is fixed now). ... nextBytes , which is used by the UUID. randomUUID factory, which definitely is thread-safe.

Using JSP Error Pages Any runtime error encountered during execution of a JSP page is handled using the standard Java exception mechanism in one of two ways: You can catch and handle exceptions in a Java scriptlet within the JSP page itself, using standard Java exception-handling code.

Spring framework does not do anything under the hood concerning the multi-threaded behavior of a singleton bean. It is the developer's responsibility to deal with concurrency issue and thread safety of the singleton bean. While practically, most spring beans have no mutable state, and as such are trivially thread safe.

Each object gets its own copy of the class's instance variables - it's static variables that are shared between all instances of a class. The reason that instance variables are not necessarily thread-safe is that they might be simultaneously modified by multiple threads calling unsynchronized instance methods.

JSP is a webpage scripting language that can generate dynamic content while Servlets are Java programs that are already compiled which also creates dynamic web content. In MVC, jsp acts as a view and servlet acts as a controller.

On First JSP, we created local variable 'name' using JSTL Core tag c:set. This variable has a value 'Dinesh' and assigned 'request' scope using scope attribute of c:set tag. We also use jsp:forward tag to forward the same request to another JSP.

It is simple. You can use any loop together with (volatile) boolean variable inside run() method to control thread's activity. You can also return from active thread to the main thread to stop it. This way you gracefully kill a thread :) .
