where name is the value coded in the JSP tag In the JSP page, we ll use the old tag to get the Web server product name and the new tag to get the Allow header Because the tag handler makes an HTTP request using the OPTIONS method, the server should return an Allow header that lists the request methods it will accept Here is the updated page, named ShowServerHeaderjsp:

GetWebServerTag tag1 = (GetWebServerTag) JRunJSPStaticHelperscreateTagHandler (pageContext, "GetWebServerTag"); tag1setPageContext(pageContext); tag1setParent(null); tag1doStartTag(); if (tag1doEndTag() == TagSKIP_PAGE) { return; } outprint("\r\n" + "are\r\n" + "<H4>"); GetWebServerHeaderTag tag2 = (GetWebServerHeaderTag) JRunJSPStaticHelperscreateTagHandler (pageContext, "GetWebServerHeaderTag"); tag2setPageContext(pageContext); tag2setParent(null); tag2setName("allow"); tag2doStartTag(); if (tag2doEndTag() == TagSKIP_PAGE) { return; } outprint("</H4>\r\n\r\n</BODY>\r\n\r\n</HTML>\r\n"); }

Near the beginning of _jspService(), the servlet creates and initializes its page context:

PageContext pageContext = __jspFactorygetPageContext (this, request, response, null, false, 8192, true);

The JspFactory has a getPageContext() method that takes a reference to the current servlet, the request and response objects, the URL for the error page (if any), a

flag indicating whether the page needs an HTTP session, the output buffer size, and a flag indicating whether the buffer should be autoflushed The method returns an initialized page context that encapsulates all these objects

JspWriter out = pageContextgetOut();

Having initialized a page context object, the servlet uses it to obtain a reference to the response output writer The tag handler can use this same method call to do its own output to the page, if desired The issue becomes slightly more complicated for tag handlers that interact with their body content, as we will see in the next section

How to easily implement QRCoder in ASP . NET Core using C#
23 May 2019 ... Run your application and go to the URL — ' http://localhost:50755/QRCoder ' to invoke the Index Action method. In the text box, add your text and click the submit button to create the QR Code Bitmap image.

GetWebServerTag tag1 = (GetWebServerTag) JRunJSPStaticHelperscreateTagHandler (pageContext, "GetWebServerTag");

After printing the page headings, the servlet creates an instance of the tag handler, using a static method in a helper class This helper class may use a pool of tag handler instances or perform other optimizations the JSP specification doesn t dictate how this should be done This affords servlet engine vendors the opportunity to distinguish their product s performance and functionality

tag1setPageContext(pageContext); tag1setParent(null);

As the flowchart in Figure 11-2 indicates, the generated servlet then calls the tag handler s setPageContext() and setParent() methods No parent tag exists in this case, so the parameter value is null

tag1doStartTag();

With the page environment thus fully described to the tag handler, its doStartTag() method is called Note, no return code is captured, even though doStartTag() returns one The reason for this is the TLD indicates the getWebServer tag has no body (<bodycontent>empty</bodycontent>), so no conditional code is generated to handle it The JSP container is able to optimize the code rather than checking a meaningless return value

if (tag1doEndTag() == TagSKIP_PAGE) { return; }

The doEndTag() method can return either EVAL_PAGE or SKIP_PAGE The effect of each becomes clear when we see that SKIP_PAGE simply causes a return from the _jspService() method After printing the intervening HTML, the servlet begins work on the second tag:

GetWebServerHeaderTag tag2 = (GetWebServerHeaderTag) JRunJSPStaticHelperscreateTagHandler (pageContext, "GetWebServerHeaderTag"); tag2setPageContext(pageContext); tag2setParent(null); tag2setName("allow"); tag2doStartTag();

The only difference between the handling of this tag and the previous one results because the getWebServerHeader tag has a name attribute This is transformed into a call to the tag handler s setName() method just before doStartTag() is called The end tag is handled the same, with its return code determining whether to exit from the _jspService() method or continue
