  • Program from Core Java book

    I am running Java using the latest download version (1.4.1_02, I think?) from Sun on Windows XP Pro.
    On page 25 of the book Core Java, there are instructions for running the Welcome program. The book says to first type "javac Welcome.java." This works fine because after doing this, I have a file Welcome.class. However, the next step is to type "java Welcome." When I do this, I get an error "Exception in thread "main" java.lang.NoClassFoundDefError: Welcome." The program Welcome comes with the CD that comes with the book, and I have only viewed it, I have not modified it in any way.
    I have downloaded the JDK several times, and I still get this same error, so I do not think the problem is with downloading.

    Thanks for the info. In line with this lame-ass Java
    crap, when I type in "java classpath .Welcome" after
    getting to the correct subdirectory, I get the message
    "Exception in thread "main"
    java.lang.NoClassDefFoundError: classpath." Looks
    like I'm back to square one again! Nothing like a
    total shit book with lame-ass fucking directions.You mis-read or mis-typed. It is
    java -classpath . WelcomeThere is a space between each of these
    java
    -classpath
    Welcome

  • How to move further from Core JAVA.

    Hi,
    I have studied Core JAVA upto multithreading.
    And currently as S/w Quality Engineer, I am working on JUnit Tests in Spring Framework from last 2 months.
    Now, I want to switch into development, and for the same I want to learn more in JAVA.
    Please advice what more I need to learn to make myself proficient in JAVA so as that I can switch to development.
    Thanks !

    I'm surprised by statement in the OP:
    as S/w Quality Engineer, I am working on JUnit Tests in Spring FrameworkBut even more by this answer:
    if you can push yourself to a professional level in the department of testing (creating and executing test plans, writing proper unit tests, doing test driven development, ...).I'm not disagreeing, just wondering: I have never met a professional "tester" that used jUnit. The testers I've met in organizations, even when they were were technical (usually graduated from programming to testing), had a mostly functional concern: check that a functionality works as expected. Creating and executing test plans, while an invaluable skill, is rarely matching the same job description as "writing unit tests".
    Even integration testing, which requires development for injectors, simulators, etc... is not always (and I would say, rarely) amenable to using jUnit.
    I seem to understand the OP means in-container automated tests. I understand how they can be referred to as integration tests (*not* unit-tests).
    I have met (and been) developers who test their software, including at an integration or functional level, using jUnit or not, but they were "developers" who had acknowledged the importance of testing (conscientious developers, that is), not "testers" using jUnit as one of their tools.
    One thing I can understand to justify a specific team writing in-container testing as those described, is an integration team integrating modules developed by several teams. Even then, I would call people in such a team developers, not testers.
    Again I'm not disagreeing, just surprised: could you both comment on your experience as to how unit-testing can be a tester's concern as opposed to a developer's concern?
    Are you working in organizations where full-time people in a QA team are devoted to write unit-tests or jUnit tests over code produced by other full-time people?

  • Questions from a Java newbie

    Okay, here's my situation:
    I'm fairly new to Java, but I've done some fairly basic client-side java. However, I haven't done any server-side java stuff before, and I don't know what special considerations I 'll have to make, etc. And I don't really know how to do the things I'm asking about below:
    What I want to do is this:
    1) Grab the Computer Name and Company Name from a computer when the user loads a webpage. This then needs to be stored in a server-side database.
    2) Password protect a webpage, so that only users who enter the correct username/password can view it. I presume the username/password data will also be stored in a server-side database.
    Now, I'm really not sure how to do this, and I'd like at least a few pointers on how to go about it. In fact, any help at all would be appreciated.
    Adrian Forest - Java Newbie

    Actually, any sample code you could give, even showing just one possible solution, would be greatly valued.
    Also, I really don't know how server-side java works, as far as where I have to run these actions. Can I have some server-side code that reads the data from a client? Or do I need a client-side piece that reads data, then sends it to the server-side code that then writes that data to the database?

  • Enum - core java II example

    hi
    the following code is an example taken from 'core java II'-book.
    what i don't understand is where the enum constructor is called
    to set the abbreviation field
    anyone care to explain ?
    thanks
    import java.util.*;
    public class EnumTest {
        public static void main(String[] args) {
            Scanner in = new Scanner(System.in);
            System.out.print("Enter a size: (SMALL, MEDIUM, LARGE, EXTRA_LARGE) ");
            String input = in.next().toUpperCase();
            Size size = Enum.valueOf(Size.class, input);
            System.out.println("size=" + size);
            System.out.println("abbreviation=" + size.getAbbreviation());
            if (size == Size.EXTRA_LARGE) {
                System.out.println("Good job--you paid attention to the _.");
    enum Size {
        SMALL("S"), MEDIUM("M"), LARGE("L"), EXTRA_LARGE("XL");
        private Size(String abbreviation) {
            this.abbreviation = abbreviation;
        public String getAbbreviation() {
            return abbreviation;
        private String abbreviation;
    }

    so from what i get here is that
    SMALL("S"),MEDIUM("M"),LARGE("L"); are the constructors from where abbreviations are taken.
    I want to clear one more doubt.
    private Size(String abbreviation) {
            this.abbreviation = abbreviation;1. This is also a constructor right ? If yes then, what was the need that the author made this constructor private ?
    2. Why public modifier is not allowed there ?
    3. Size s = Enum.valueOf(Size.class,input);Over here what is the role of argument Size.class ?
    4. enum size
    Size s = Enum.valueOf(Size.class,input);In the first code enum's e is small but in the second code Enum's E is capital. How so ?

  • Questions abt. calling Java from C

    I have a java class that contains a method I need to make accessable to C functions. It looks something like this:
    public class ExportName
       private SomeObj theObj;
       public ExportName(SomeObj theObj)
          this.theObj = theObj;
       } //end ExportName
       public String getName()
          return theObj.getName();
       public native String getNameJNI();
    }Using javah I have my ExportName.h, and I'm in the process of writing ExportName.c:
    #include <stdio.h>
    #include <jni.h>
    #include "ExportName.h"
    JNIEXPORT jstring JNICALL Java_ExportName_getNameJNI (JNIEnv *, jobject)
       jclass cls = (*env)->GetObjectClass(env, obj);
       jMethodID mid = (*env)->GetMethodID(env, cls, "getName", "()Ljava/lang/String");
       if (mid == 0)
          return;
       } /* end if */
    }I have 2 questions:
    (1)At some point, I need to actually call the java method using
    (*env)->Call<TYPE>Method(env, obj, mid);
    What type should I use here (CallWhatMethod)?
    (2)Also, I need to create genuine C wrappers for these methods. How do I hand off the jstring returned by this JNI C code to the ANSI C method that calls it? I know that there is a conversion along the lines of:
    const char str = (env)->GetStringUTFChars(env, <<JSTRING HERE>>, 0);
    Can I just put the call to the JNI method where the jstring variable name goes?
    Any help would be appreciated. I have already read the Java tutorial on JNI, so please don't respond just to tell me to go there.
    Thanks!

    If that is the case, then your starting point is not javah, but to investigate the invocation API, after which you will call java methods from C.
    Well, the Invocation API is mostly orthogonal to whether you are calling Java from C or vice versa. The Invocation API is mostly about creating/destroying VMs. You can call Java methods from a flat C application or you can call Java methods from C from within Java native methods.
    If you want to call Java from C, you need to use the methods you're using like GetMethodID, CallXXXMethod, etc...
    In your particular example, if you wanted to call ExportName.getName(), you would use CallObjectMethod. You would cast the result to a jstring, and then use GetStringUTFChars, ReleaseStringUTFChars, etc...
    God bless,

  • How to call a text FTP proxy service from a Java client ?

    Greetings,
    I've configured a text FTP proxy service which downloads files from a FTP server. It pols a directory on the FTP server and, as soon as a file respecting a given pattern apears it is downloaded. I tested the service in the test console and by putting some test files onto the FTP server. Now, I need to be able to test it from a Java client. How may I do that ? I need to write a Java client to connect to the OSB and to tell to it to use the FTP proxy in order to download a given file, from a given location and to put it in a given location on the client machine. Many thanks in advance for any help. A sample would be great !
    Kind regards,
    Nicolas

    Ok, I understand. The crucial question here is "what is a caller that you refer to?"
    Don't get me wrong, but the problem here is that you probably don't understand, what OSB is good for. OSB is an event-driven system. The event in your case is a new message in remote FTP server. You have to define what should happen when that event is fired. And that's all. You don't have to involve other client (or caller) for this case.
    You should define your FTP proxy to retrieve all relevant files from FTP server and then you should route them based on their name/content/encoding/whatever to different consumers. You can also have many proxies if you want - one for each name. It's up to you. But you don't have any "callers" in either case.

  • Re-use message mapping from within java mapping?

    Hi there,                                                                               
    I have a question regarding java mapping. What I would like to do is to re-use an existing message mapping from within java mapping.
    Technicaly, message mapping is perfomed by com.sap.aii.mappingtool.tf3.AMappingProgram.execute, right? I would like to call that mapping program for a specifc message mapping from within my java mapping.
    Pseudo java code would look like this:
    public void execute(InputStream in, OutputStream out)
      throws StreamTransformationException {
    com.sap.aii.mappingtool.tf3.AMappingProgram.execute(in,out,'SomeMessageMapping');
    SomeMessageMapping is a message mapping that is defined in the integration repository.
    Is it possible? If so, could you provide me with some details?
    Thank you and best regards,
    Wolfgang

    Hi Wolfgang,
    very interesting idea?
    I would activa a dummy message mapping. than I would have a look in the file directory of the java-stack and try to find out the name of the *.class or *.jar file.
    On the other hand you could generate a tpz-transport-file an unpack this file, to explore the name of the *.class or *.jar
    Unfortunately I do not have access to the file system. So I can't explore the name.
    Regards Mario

  • H to generate popwindow in core java

    hi friends,
    i faced some proble in core java.h to create pop up window like in VB.
    with in the pop ,database fields should disply with jtable. when i click any one of the row.the text with in that row should display in some other text boxe. plz send code if any body have.give some views on that.
    ok bye.

    Thank you for replay, may steps are same:
    1. I have created Java Project With Existing Source
    2. selected directory with code (not whole project but directory with java classes)
    3. After that I have created UML Java Specific project and
    4. Associated UML project with previous created java project
    5. I have selected "Code Generation" check box
    6. Classes from java project were reversed into UML model.
    7. After that I have created new class in java project.
    And there is no Generate code action in this class context menu, also this class do not appeared in code automatically.
    From UML project properties it is shown that UML project is associated with proper java project)
    Same is with Java Application project associated with UML java project.
    Documentation do not talks more about this. Only same steps. It looks like code generation should be working but it isn't. I'm I only one who face this problem, or do smth wrong?
