'Jpanel' cannot be resolved to a type error

Hi all,
I need to pass a Jpanel to an object. I have added my code below.
public void createFrame(Object panel){
          JFrame frame = new JFrame();
          frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
          frame.getContentPane().add( (Jpanel)panel);
          frame.pack();
          frame.setVisible(true);
     }In this
frame.getContentPane().add( (Jpanel)panel);shows error as 'Jpanel' cannot be resolved to a type.
What is the correct approach for this?
Please help.

Also, why is your method parameter an Object? Why not a JPanel or at least a JComponent?

  • Eclipse "cannot be resolved to a type" and new .JAR lib - config prob?

    I'm trying to make use of the Commons HttpClient library in a project being built in Eclipse (3.1). I have a sample program (PostXML) that runs into "cannot be resolved to a type" on the "HttpClient" object. I think the problem is that the JRE 1.4.2 (Mac OS-X) system library includes an earlier release (3.0.1) of the HttpClient, but some of the classes used by PostXML are in the 3.1rc of HttpClient. I've downloaded the newer release, created a user library, and modified the load order so I can see the user library above (i.e. loaded prior to?) the System JRE in the package browser. I can see the HttpClient.class in the Package browser. I have "import org.apache.commons.httpclient.methods.*;" in the head of the application (that took tweaking). Several of the HttpClient methods resolve correctly, but not the HttpClient object constructor itself. I am also finding I cannot simply import all the HttpClient methods, but must import each explicitly (?). Suggestions?

    I have gotten the sample code to compile and run,
    though I still have some confusion about needing the
    explicit imports (as compared to a wildcard import).
    In the end I believe my "cannot be resolved to a
    type" error was due to dependencies within the
    HttpClient library on the commons-codec library. Once
    I downloaded and installed that, the samples started
    working better. Still trying to understand the API,
    but making progress.when downloading third-party libraries, check the download page to see if it has any further dependencies. apache libraries are notoriously dependent on other apache libraries
    regarding the imports, it's not that there's a need for explicit imports, it's more that wildcard imports are a bad idea. explicit imports gives other people looking at your code a first clue as to what it does, and it also can serve as an indicator that your class is too big, if there are lots of imports. wildcards hide this from you. apart from that, it makes no difference to your code, and imports don't even exist at runtime so it affects how your code actually runs, not at all

  • Include JSP in JSP - Error:  cannot be resolved to a type

    Hello,
    Several of my jsp pages include other jsp pages. The project has many errors: "x cannot be resolved to a type". Is there a way to resolve these errors? Below is a small example of the issue:
    JSP #1:
    <%@ page import="com.testing.Introduction" %>
    <html>
    <head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>Hello</title>
    </head>
    <body>
    <%
         Introduction intro = new Introduction();
         String speak = intro.sayHello();
    %>
    <p><%=speak %></p>
    <%@ include file="Name.jsp" %>
    </body>
    </html>  JSP #2:
    <html>
    <head>
    <title>Name</title>
    </head>
    <body>
    <%
         String speak2 = intro.sayName();
    %>
    <p>
    <%=speak2 %>
    </p>
    </body>
    </html>Class:
    package com.testing;
    public class Introduction
         public static void main(String[] args) {
         public Introduction() {
              super();
         public String sayHello() {
              return "Hello";          
         public String sayName()     {
              return "My name is Sam";
    }The error shows up in Name.jsp; the issue is with "intro". Any ideas how to resolve this issue?
    Thank you in advance for your help!

    The jsp page Name.jsp appears to be missing the import statement that appears in the first page.
    <%@ page import="com.testing.Introduction" %>The included file is included character for character into the main page which is then treated as a single jsp page for the response. The include directive is invoked at the time of page translation. Given this, I don't see the purpose of using the <html> <head> and <title> tags in the second and included page. I don't think that this suggests the proper purpose of the include directive.
    Note too that if the included file changes, all of the jsp files that call this file need to be updated as well. Servers can handle the alteration of the main jsp, but may not serve the altered content if the included file changes.
    For more information see here. http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/JSPIntro8.html

  • Error "Cannot be resolved to a type" on OwnerPIN, APDU, ISO7816

    The error I'm reffering to might clearify the fact that I'm new at Java/javaCard-development.
    To learn how it all works I've downloaded an example and try to understand what happens.
    I opened the source in Eclipse and get errors "Cannot be resolved to a type" on OwnerPIN, ADPU and ISO7816 classes. I have an Import javacard.framework statement and expected these types to be part of this library.
    I guess I'm forgetting something somewhere but couldn't find the soluiton on internet.
    import javacard.framework.*; // import all neccessary packages for java card*
    import java.applet.;
    import java.lang.Object;
    public class classpgdata extends Applet {
    final static byte PROP_CLASS = (byte) 0x80; // Class of the proprietary APDU commands
    static {color:#ff0000}OwnerPIN{color} pin; // the PIN object
    public void process({color:#ff0000}APDU{color} apdu) {
    byte[] cmd_apdu = apdu.getBuffer();
    if (cmd_apdu[{color:#ff0000}ISO7816{color}.OFFSET_CLA] == {color:#ff0000}ISO7816{color}.CLA_ISO7816) {
    //----- it is the ISO/IEC 7816 class
    switch(cmd_apdu[{color:#ff0000}ISO7816{color}.OFFSET_INS]) { // check the instruction byte
    case INS_SELECT: // it is a SELECT FILE instruction
    ...

    Hi,
    What you need to do update your Java build path fr the project in your Eclipse project.
    Project -> Properties then find Java Build Path.
    In the Libraries tab add the {JCDK Home}/lib/javacardframework.jar by clicking the add external JARs button. You may also want to remove the standard Java Runtime (JRE) libraries as you do not build against these.
    If you want to use the JC 2.2.1 CAP file converter, you may also want to ensure that the Eclipse compiler is set to compile as Java 1.3 in the Java Compiler section of the project properties.
    KeesdeVink wrote:
    import javacard.framework.*; // import all neccessary packages for java card
    import java.applet.*;
    import java.lang.Object;
    It also looks like you have added two imports you don't actually want. You only need the javacard.framework.* import.
    Cheers,

  • GEF4 Setup Error - FXCanvas cannot be resolved to a type

    Hallo,
    I tried to setup the development environment for GEF4, as specified in the GEF Contributor guide, and I found the following error:
    FXCanvas cannot be resolved to a type.
    (se attached file)
    This error is persistent, and it seems i am not able to find a solution despite I tried multiple times to setup the environment, as specified in the GEF/GEF4 contributor guide .
    This is the list of steps I followed for the setup
    Check Java 8 (oracle) is installed, that is required by the e(fx)clipse plugin.
    Download Eclipse IDE for Eclipse Committers. In my case: eclipse-committers-mars-R-win32.zip
    Install plugins needed by GEF4, in my case:
    e(fx)clipse - IDE, from http://download.eclipse.org/efxclipse/simrel-contrib/mars/m7/tools/site
    e(fx)clipse - IDE - PDE, from http://download.eclipse.org/efxclipse/simrel-contrib/mars/m7/tools/site
    API Tools Execution Environment Descriptions, from: http://download.eclipse.org/eclipse/updates/4.5-I-builds
    Oomph Version Management, from: http://download.eclipse.org/releases/mars'
    Maven Integration for Eclipse (includes Incubating components), from: http://download.eclipse.org/releases/mars
    Clone the GEF4 Git repository and import the projects in the workspace
    Set MARS.target: from org.eclipse.gef4.target project, double click the target definition, wait for the target is fully resolved, and click on "set as target platform".
    Adjust preferences. select Menu > Window > Preferences:
    Java > Compiler > Errors/Warnings: ignore the "Deprecated and restricted API"
    Plug-in Development > Compilers: Ignore the "References to discouraged classes"
    At the end of the setup, I can not compile the GEF4 project, because "FXCanvas cannot be resolved to a type. "
    See image.
    Does anyone has an idea on how to fix this ?
    Kind Regards.
    Patrik

    I updated the respective section of the contributor guide to make it even more explicit, why the "Specify Execution Environment for J2SE-1.7 (and optionally J2SE-1.8)" is important. I also saw that the guide still listed the e(fx)clipse 2.0.0 Mars M7 contribution. I updated it to refer to the e(fx)clipse 2.0.0 Mars release. You might want to update your IDE accordingly.

  • JspWriter cannot be resolved to a type

    The following is CheckAddress.jsp page which checks if the form has the name and phone fields filled in or not. If not then it must print the errors. But the problem I am having is that the Eclipse is showing me the error "JspWriter cannot be resolved to a type".
    If I ignore this error and run the page in the j2ee preview server in eclipse than I get the following error:
    >

    Thanks elOpalo, even though eclipse is still showing the error, things are running fine after I rectified my typing mistake about the prinln. :)

  • Class name cannot be resolved to a type

    I have one main class calling another class but I keep getting this error "

    Dear Ejp,
    I would like to first share a simple case here first. Below is the simplied codes. Here I dont need any import statement. I keep both this in the same directory. I am using this command to compile javac callSMSClient.java. Why even this simple case is not working?
    public class callSMSClient{
      public static void main(String[] args)
           SMSClient t1 = new SMSClient(1);
           t1.sendMessage("+6014466044","testing one two");
    public class SMSClient {
      private int mode=-1;
      private String recipient=null;
      private String message=null;
      public SMSClient(int mode) {
          this.mode=mode;
      public void sendMessage (String recipient, String message){
        this.recipient=recipient;
        this.message=message;
        System.out.println("recipient: " + recipient + " message: " + message);

  • Can't use classes in own package ... cannot be resolved into a type

    I am fairly new to java and I am having the following problem.
    i have a folder structure that goes as follows:
    cs/uwm/client/io
    and in this directory I have 3 files: ConsoleReader.java ConsoleWriter.java and ConsoleManager.java
    and at the top of all three I have the following:
    package cs.uwm.client.io;
    ConsoleReader and ConsoleWriter are compiling fine
    However in ConsoleManager I am using these classes ConsoleReader/Writer and It compile fine for me on a windows JDK in cywin, but when I try this on a Fedore6 system with an Eclipe Java Compiler v_686_R32x, 3.2.2 release I have the following error:
    ConsoleWriter cannot be resolved into a type
    when I try the following line: ConsoleReader reader = new ConsoleReader( System.in );
    I tried importing cs.uwm.client.io but that didnt' work. I couldn't find anything on the forums here if you are trying to use a class defined in your package inside your package the way I am.
    Any help would be great!

    So it compiles from a commandline invocation of Java, but not from within Eclipse?
    Sounds like you need to ask the question at an Eclipse site, since the problem is not a Java problem - and this forum is for Java language questions, not IDE support questions.
    Probably caused by the fact that Eclipse doesn't use Sun's Java compiler.

  • Some class that cannot be resolved to a type

    Hello, I?m trying to use the[b] itext API for PDF creating from Java.
    In order to do this you must include the package .jar in your classpath and import com.logawie.text.* in your java file. All this steps are obviusly, and work correctly, in JAVA, but i?m trying to develope a web application, using JSP.
    Usually when I try to import a package from a JAR file that are allocated in the C:\j2sdk1.4.2_12\lib directory it doesn?t work. I solved this problem with some classes including it directly to the src.zip file. But with the itext package it doesn?t work, I don?t know if my solution is too bad, but with another classes it works, but with the itext package it says that all classes references "cannot be resolved to a type".
    Anyone can help me? Thanks in advance.
