To open a PDF file in a servlet, you set the content type in the response header to "application/pdf" : // MIME type for pdf doc res.setContentType( "application/pdf" ); Every method you write eventually gets compiled into a static C function. Pointers to these functions populate the dispatch tables of each Class object. The compiler hides the names of these functions, so you are never exposed to them. But Objective-C will provide the address of each, making it possible to call methods directly bypassing all of the nominal message dispatch logic. This technique is somewhat technical, but is useful if you ever need to invoke Objective-C methods from some other programming language or where message dispatching has a significant impact on performance. The method -methodForSelector: returns the implementation the address of the method s code that will execute when the receiver is sent that message. The class method +instanceMethodForSelector: returns the address of the code that will nominally execute when an instance is sent that message. I ve chosen my words here very carefully. An individual object can be modified so that the code executed when sent a message is different than the code executed by another object of the same class, or even the code that the Class object assumes each instance will execute. Don t casually assume that the method implementation address for one object is the same as that for another instance, or equal to the address returned by -[Class instanceMethodForSelector:]. The safest practice is to query an individual object for its implementation address and only use that address for that object. Read 26 (the isa Swizzling section) to get a better idea about how and why an object s methods might be dynamically altered. The C function generated for each method expects a receiver object pointer (self) and a selector (_cmd) as the first two parameters. Any remaining parameters mirror those defined by the method. Listing 6-9 demonstrates calling a method via its implementation address. pdf reader java: Java PDF Viewer - Stack Overflow how to open pdf file in jsp page Open pdf file in browser - Experts Exchange

The most fundamental of enumeration techniques is banner grabbing, which was mentioned briefly in 2 Banner grabbing can be simply defined as connecting to remote applications and observing the output, and it can be surprisingly informative to remote attackers At the very least, they may have identified the make and model of the running service, which in many cases is enough to set the vulnerability research process in motion As also noted in 2, many port-scanning tools can perform banner grabbing in parallel with their main function of identifying open ports (the harbinger of an exploitable remote service) This section will briefly catalog the most common manual techniques for banner grabbing, of which no self-respecting hacker should be ignorant (no matter how automated port scanners become) jsp code to open pdf file in browser jPDFViewer - Java PDF Reader / PDF Renderer for Java

Sep 1, 2014 · How to display a pdf file in browser using java. response.setContentType("application/pdf"); response.setHeader("Content-Disposition", "inline; filename='" + pdfName + "'"); if (containsPointImpl(path,@selector(containsPoint:),pointArray[i])!=NO) return YES; return NO; } @end The -containsAnyPoint:pointCount: method of BezierPathMapper tests a sequence of coordinates to see if any reside inside its path property The method begins by getting the implementation address of the path s -containsPoint: method The crazy syntax you see surrounding this is how you declare a pointer to a function in C The type consists of a complete function prototype describing the function s parameters and return type (BOOL foo(id self, SEL _cmd, NSPoint point)), with the name of the function replaced with a pointer declaration ((*containsPointPtr) replaces foo) The result is a variable that points to a function with that prototype In a typedef statement, it results in a new pointer type In Listing 6-9, a typedef is used so the entire function prototype doesn t have to be repeated when casting the value returned by -methodForSelector:. Popularity: Simplicity: Impact: Risk Rating: 5 9 1 5 (c) 000004 (d) 00294 (e) 01111 C allows a function pointer variable to be used as a function name, just as if there was a function named containsPointImpl The receiver and selector parameters must be included in the call While the selector is often ignored, it s always good programming practice to pass the selector constant of the method being called Since this technique bypasses the dispatcher s nil receiver test, this code must first make sure that the function is never called for a nil path object that would most likely cause the program to crash The code in Listing 6-9 is principally to demonstrate the technique It s unlikely to result in any significant performance gains, even when testing thousands of points mostly because the computations performed by -[NSBezierPath containsPoint:] probably far outweigh the trivial overhead of sending the message. The tried-and-true manual mechanism for enumerating banners and application info has traditionally been based on telnet (a remote communications tool built into most operating systems) Using telnet to grab banners is as easy as opening a telnet connection to a known port on the target server, pressing enter a few times, if necessary, and seeing what comes back: how to open a pdf file on button click in java Java PDF Viewer by BFO - A full-featured Swing PDF Viewer
