This isn’t a bug, it’s by design. When a new session is created, the server isn’t sure if the client supports cookies or not, and so it generates a cookie as well as the jsessionid on the URL. When the client comes back the second time, and presents the cookie, the server knows the jsessionid … Read more
The issue is that the Tomcat admin port was not defined. You need to have it as an actual number such as 9000 rather than as a hyphen -.
You’re trying to use Spring MVC’s form tag. This tag renders an HTML form tag and exposes a binding path to inner tags for binding. It puts the command object in the PageContext so that the command object can be accessed by inner tags. [..] Let’s assume we have a domain object called User. It … Read more
You need to iterate over the ResultSet object in a loop, row by row, to pull out each column value: List ll = new LinkedList(); ResultSet rs = stmt.executeQuery(“SELECT userid, username FROM USER”); // Fetch each row from the result set while (rs.next()) { int i = rs.getInt(“userid”); String str = rs.getString(“username”); //Assuming you have … Read more
You need to use declaration syntax (<%! … %>): <%! public String doSomething(String param) { // } %> <% String test = doSomething(“test”); %>
You should use single quotes on the value parameter, ie: value=”<%=request.getParameter(“userName”)%>” or set the org.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING parameter to false as described here: http://blogs.sourceallies.com/2009/10/strict-quote-escaping-in-tomcat/
Though CDATA works fine, using document.createElement is also a great choice.. Especially if you intend to append some value to a URL, say for cache busting.. <script type=”text/javascript”> var JSLink = “/Folder/sub_folder/version.js?version=” + Math.random(); var JSElement = document.createElement(‘script’); JSElement.src = JSLink; JSElement.onload = OnceLoaded; document.getElementsByTagName(‘head’)[0].appendChild(JSElement); function OnceLoaded() { // Once loaded.. load other JS or … Read more
You seem to concentrate on only the presentation and flow-control part of the scriptlets as in using if, for and switch statements and out.print() things. You seem to compare scriptlets 1:1 with JSTL. This is wrong. I was not talking about the flow control part only (which is indeed to be replaced by JSTL), but … Read more
JSTL variables are actually attributes, and by default are scoped at the page context level. As a result, if you need to access a JSTL variable value in a scriptlet, you can do so by calling the getAttribute() method on the appropriately scoped object (usually pageContext and request). resp = resp + (String)pageContext.getAttribute(“test”); Full code … Read more
You are not adding the object to the session, instead you are adding it to the request. What you need is: HttpSession session = request.getSession(); session.setAttribute(“MySessionVariable”, param); In Servlets you have 4 scopes where you can store data. Application Session Request Page Make sure you understand these. For more look here
