When you don't create any folders to hold your classes (called packages in Java), your classes are considered to be in a "default package". Another way of thinking about it is that these classes do not have a package. Note that the package namespace is relative to the directory you specify as java source root. In your case, it looks like you designated the servlets directory as a source root. The default package node that you are seeing in the Project Explorer doesn't correspond to anything physical on disk. It just there to help you understand the above situation. If you are happy with your classes not having a package specified, then you don't need to do anything. > Second problem linked to the first one: > using the Eclipse internal web browser, I type in the URL: > http://localhost:8080/EtiquettesWebProject/jsp/FormUploadFile.jsp > and I properly get my form. > I think it would have been more appropriate to type in the URL: > http://localhost:8080/EtiquettesWebProject/WebContent/jsp/FormUploadFile.jsp > What is the rationale behind it? The WebContent directory is the root for the web content contained in your app. The reason that the web content root is not set as the project root is that you don't want to be picking up various project metadata files, java source files, etc when resolving URLs. You can control the directory that's designated as the web content root either at project creation or in project properties (search for web). > Can you tell me if something is wrong whith this > because when I submit the form, the servlet is not > executed: the form is re-printed on the screen > and re-initialized. You aren't specifying the servlet as the target of your action in your HTML form element. The standard HTML behavior in this case is to send your POST request to URL that originates it, which is what you are seeing. - Konstantin -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of lmhelp Sent: Wednesday, February 11, 2009 2:23 AM To: [email protected] Subject: [wtp-dev] [Dynamic Web Project] JSP - Servlet - web.xml Hi everyone, Thank you for reading my post. Let me explain you what I am trying to do and what my problems are. I created a new "Dynamic Web Project" using Eclipse. The "Project Explorer" view shows the following architecture: (L1 = Level 1, ..., L5 = Level 5) -------------------------------------------------------------- 1. L1 -- WebProject 2. L2 -- -- Java Resources 3. L3 -- -- -- src 4. L3 -- -- -- servlets 5. L4 -- -- -- -- (default package) 6. L5 -- -- -- -- -- ClassUploadFile.java 7. L3 -- -- -- Libraries 8. L4 -- -- -- -- Apache Tomcat v6.0 [Apache Tomcat v6.0] 9. L4 -- -- -- -- EAR Libraries 10. L4 -- -- -- -- JRE System Library [jre6] 11. L4 -- -- -- -- Web App Libraries 12. L2 -- -- JavaScript Support 13. L2 -- -- build 14. L2 -- -- WebContent 15. L3 -- -- -- jsp 16. L4 -- -- -- -- FormUploadFile.jsp 17. L3 -- -- -- META-INF 18. L3 -- -- -- WEB-INF 19. L4 -- -- -- -- lib 20. L4 -- -- -- -- web.xml 21. L1 -- Servers 22. L2 -- -- Tomcat v6.0 Server at localhost-config -------------------------------------------------------------- As you can see, I have created: - a folder: "jsp" (line 15.), - a "Source Folder": "servlets" (line 4.) - two files: a JSP "FormUploadFile.jsp" (line 16.) and a servlet "ClassUploadFile.java" (line 6.). Roughly, - the JSP is a HTML form that I want to use to choose the file I want to upload, - the servlet does the uploading job. My first problem is the following: I do not really understand the architecture above and didn't find the reference documentation that explains it. I only had a glance at the file: ".settings\org.eclipse.wst.common.component" which seems to be linked to the problem... ---------------------------------------------------------------------------- ---- <?xml version="1.0" encoding="UTF-8"?> <project-modules id="moduleCoreId" project-version="1.5.0"> <wb-module deploy-name="WebProject"> <wb-resource deploy-path="/" source-path="/WebContent"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/src"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/servlets"/> <property name="context-root" value="WebProject"/> <property name="java-output-path"/> </wb-module> </project-modules> ---------------------------------------------------------------------------- ---- Tiebreaker: what is that "default package" that was created? What to do with it? Second problem linked to the first one: using the Eclipse internal web browser, I type in the URL: http://localhost:8080/EtiquettesWebProject/jsp/FormUploadFile.jsp and I properly get my form. I think it would have been more appropriate to type in the URL: http://localhost:8080/EtiquettesWebProject/WebContent/jsp/FormUploadFile.jsp What is the rationale behind it? Third problem: I have to customize the "web.xml file". Here is what is presently looks like: ---------------------------------------------------------------------------- ---- <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns="http://java.sun.com/xml/ns/javaee"; xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; id="WebApp_ID" version="2.5"> <display-name>WebProject</display-name> <servlet> <display-name>ClassUploadFile</display-name> <servlet-name>ClassUploadFile</servlet-name> <servlet-class>ClassUploadFile</servlet-class> </servlet> <servlet-mapping> <servlet-name>ClassUploadFile</servlet-name> <url-pattern>/FormUploadFile</url-pattern> </servlet-mapping> </web-app> ---------------------------------------------------------------------------- ---- Can you tell me if something is wrong whith this because when I submit the form, the servlet is not executed: the form is re-printed on the screen and re-initialized. Here is the "FORM" in the JSP file: ---------------------------------------------------------------------------- ---- <FORM ENCTYPE="multipart/form-data" ACTION="" METHOD="POST"> <TABLE STYLE="background-color: lightgreen;" CELLPADDING="5"> <TR> <TD> Choose a file to upload: </TD> </TR> <TR> <TD><INPUT NAME="uploadedfile" TYPE="file" style="width: 227px"/></TD> </TR> <TR> <TD COLSPAN="2"><INPUT TYPE="submit" VALUE="Submit" /></TD> </TR> </TABLE> </FORM> ---------------------------------------------------------------------------- ---- Thanks in advance for your help, -- Lmhelp -- View this message in context: http://www.nabble.com/-Dynamic-Web-Project--JSP---Servlet---web.xml-tp219518 89p21951889.html Sent from the Eclipse WTP - general mailing list archive at Nabble.com. _______________________________________________ wtp-dev mailing list [email protected] https://dev.eclipse.org/mailman/listinfo/wtp-dev _______________________________________________ wtp-dev mailing list [email protected] https://dev.eclipse.org/mailman/listinfo/wtp-dev
