page's logic. The JSP is compiled into a servlet (the JSP compiles to a servlet), as we have defined clockservlet, which is equivalent to writing the HTML section and evaluating the Java section (that's equivalent to writing Out the HTML portions,and evaluating the Java portions). In a sense, JSPs is just another way to write the servlet code.JSPs is often criticized for being too powerful. Because the entire Java language can be obtained from a JSP, there is a risk that the business logic may

Today I learned the Example 2-2 of "Advanced Programming in UNIX environment", but I am very confused.
I created a directory named sample2_2, put the source code in it, compile it, and generate the sample2_2 file. Then copy pathconf. sym and sysconf. sym to this directory.
Run the following command:
./Sample2_2 pathconf. sym
The result is as follows:
No symbol for arg_max
Arg_max = 2621440
