Ciao a tutti,
volevo innanzitutto chiedere se apache tomcat, non dovrebbe compilare automaticamente le servlet. A me, a quanto pare no. Entro nella cartella dove c'è il sorgente (/usr/local/apache-tomcat-6.0.35/webapps/app01a/WEB-INF/src/app01a), e do il comando di compilazione (javac ControllerServlet.java), 18 errori perchè non trova le librerie : import javax.servlet.*
riprovo, con: javac ControllerServlet.java -classpath "/usr/share/java/servlet-api.jar"
il messaggio è questo:
riporto il codice sia di ControllerServlet che di Product entrambi presenti nella stessa cartella:codice:ControllerServlet.java:42: cannot find symbol symbol : class Product location: class app01a.ControllerServlet Product product = new Product(); ^ ControllerServlet.java:42: cannot find symbol symbol : class Product location: class app01a.ControllerServlet Product product = new Product(); ^ 2 errors
ControllerServlet.java:
Product.java:codice:package app01a; import java.io.IOException; import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class ControllerServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { process(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { process(request, response); } private void process(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { String uri = request.getRequestURI(); /* * uri is in the form of /contextName/resourceName, * for example: /app01a/Product_input.action. * However, in the case of a default context, the * context name is empty, and uri has this form * /resourceName, e.g.: /Product_input.action */ int lastIndex = uri.lastIndexOf("/"); String action = uri.substring(lastIndex + 1); // execute an action if (action.equals("Product_input.action")) { // there is nothing to be done } else if (action.equals("Product_save.action")) { // instantiate action class Product product = new Product(); // populate action properties product.setProductName(request.getParameter("productName")); product.setDescription(request.getParameter("description")); product.setPrice(request.getParameter("price")); // execute action method product.save(); // store action in a scope variable for the view request.setAttribute("product", product); } // forward to a view String dispatchUrl = null; if (action.equals("Product_input.action")) { dispatchUrl = "/jsp/ProductForm.jsp"; } else if (action.equals("Product_save.action")) { dispatchUrl = "/jsp/ProductDetails.jsp"; } if (dispatchUrl != null) { RequestDispatcher rd = request.getRequestDispatcher(dispatchUrl); rd.forward(request, response); } } }
che ne pensate?codice:package app01a; import java.io.Serializable; public class Product implements Serializable { private String productName; private String description; private String price; public String getProductName() { return productName; } public void setProductName(String productName) { this.productName = productName; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getPrice() { return price; } public void setPrice(String price) { this.price = price; } public String save() { // add here code to save the product to the database return "success"; } }
