WL10 generated servlets from jsp pages

hi!
I'm looking for .java servlet files automatically generated from JSP (Weblogic 10). Do anybony know where can I find this files?
Thanks in advace,
Bartek

Well, Servlet and JSP both are server side technologies and both can be used in web applications. You can write web pages using both servlet and JSP. In fact, your JSP pages are converted to Servlet by container while serving requests. However, writing a JSP page is relatively easier and requires minimal Java knowledge.
When you will develop real world java based web applications you will find that you are writing more JSP pages than servlet.
In a typical MVC (Model View Controller) architecture a single servlet is used as controller and JSP pages are used to generate web content.

  • Trying to trigger a servlet from .jsp page on combo box change

    I have a jsp page with two combo boxes ( single select ).
    Here's a snippet from the jsp page containing the code for the two combo boxes:
    <form name="frmCountry" id="frmCountry" method="POST">
         <select name="selCountry" id="selCountry">
              <jsp:include page="/country" />
         </select>
    </form>
    <form name="frmCity" id="frmCity" method="POST">
         <select name="selCity" id="selCity">
              <jsp:include page="/city" />
         </select>
    </form>
    "country" and "city" are both mapped to servlets in the web.xml file
    The country servlet successfully connects to the database and retrieves all countries
    and populates the country combo box.
    However, the populating of the city combo box depends on what country
    is selected in the country combo box;
    Here is a snippet of my code from the City servlet:
    ResultSet rs;
    rs = statement.executeQuery("SELECT City.countryID, City.id, City.name " +
                   "FROM City " +
                   "WHERE City.countryID = ( Country id ) " +
                   "ORDER BY City.name");
    Where ( Country id ) has to be somehow retrieved from the Country combo box
    on the jsp page. Country id is actually the "value" property of each <option> in the
    Country combo box. i.e.:
    <option value="5">Portugal</option>
    If it's not possible to retrieve the value property from the option,
    I could always just use the Country name
    So to reiterate, I need the City servlet to be called into action
    any time a different country is selected in the country combo box.
    I'm a newbie to jsp & servlets, so any suggestions much appreciated.

    Cheers, I came up with a solution using Ajax, where I didn't have to change
    anything in my servlets and only had to make minor changes to my jsp page.
    I didn't want to use any javascript in my web app, but I guess Ajax
    has addressed the issue of cross platform independence.

    According to J2EE standards:
    The web appl directory structure should be:
    WebAppRootDirectory
    |
    |---html, jsp, images etc
    |
    |---WEB-INF---
    |---classes--
    |---lib
    |
    |
    1) Make sure WEB-INF is in capital letters
    2) Place all ur beans in classes dir or sub-directory in
    classes
    3) In Tomcat place WebAppRootDirectory in webapps
    directory

  • Dynamic generate JNLP from JSP ?

    Hello,
    I tried to generate JNLP from JSP, but it just show the Opem/Save diakog and cannot startup the Web Start.
    I am using Tomcat-5.5.12 in WinXP + JDK1.5
    How can I dynamically generate JNLP ?
    Eric

    It will range from easy to rather difficult, depending on how hard you try...
    If you want to do the bare minimum it will require you to code up some JSPs with scriptlets, declarations, expressions, and <jsp:xxx ...> tags, have some server turn them into a servlet for you, and then determine how things like
    <%@ page isELIgnored="false" %> are handled. Things like:
    <jsp:useBean ...> <jsp:setProperty ... > should be rather easy to translate using introspection on the beans they refer to. But <jsp:import ...> and the likes may be more difficult.
    Any normal html code is just wrapped inside a out.println(...) statement. Scriptlets should have the <% %> stripped and coppied to the output. Expressions should have their <%= %> stripped and be added to the surrounding out.println...
    for example:
    <a href="<%=thePage%>">
    should become:
    out.println("<a href=\""+thePage+"\">");
    All the content should be added to a _jspservice method.  Then, things between <%! %> should be coppied to source file as methods.
    Complications come when people start to use custom tags. You will have to learn how to create a PageContext that will be available to the jsp service method.
    You should also look up the JSP/Servlet spec to see how this stuff should be done.
    It is a whole nuther can o worms if the resulting JSP is expected to compile without a server...</a>

  • Error in accessing servlet from JSP

    Hello everybody,
    When I access a servlet from a JSP page,I am getting the following error message :
    Error 404--Not Found
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
    10.4.5 404 Not Found
    The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
    If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
    I am using Weblogic 7.0 and my web.xml code is as follows:
    <web-app>
    <servlet>
    <servlet-name>TestServlet</servlet-name>
    <servlet-class>TestServlet</servlet-class>
    </servlet>
    <servlet-mapping>
    <servlet-name>TestServlet</servlet-name>
    <url-pattern>/TestServlet</url-pattern>
    </servlet-mapping>
    </web-app>
    I am accessing the servlet from a javascript function in my JSP page.
    I am quite new to the Java technology. So any help in this regard would be highly appreciated.
    Thanks in advance,

    The form action event is in a javascript function. I am sorry I mentioned that I am accessing this servlet from JSP. Actually,this servlet is accessed from an HTML document.
    The following is the javascript code:
    <script language="javascript">
    function lfnCallNext()
         alert("In the function");
         frmMain.method="POST";
         frmMain.action="/TestServlet";

    please help and send the reply on [email protected],[email protected]
    thanks

    Hi Ashok,
    You can use rwservlet - nothing really to do with JDeveloper. Once you have report server up and running (hint: read http://download-uk.oracle.com/docs/cd/B14099_19/bi.1012/b14048/toc.htm), you can call a report like this:
    http://server:port/rwservlet?report=my_report.rdf&destype=cache&desformat=html&p_my_parameter=xxx etcHope this helps,
