Again with Dana Nourie tutorial...

I have this error:
DiveLog.java:79: cannot resolve symbol

new Resources(),

it repeats for all the other classes Diver(), Dives...
I know that the problem was explained in the troubleshooter part
of the tutorial but it didn't solve the problem
The java files are in the directory c:\divelog
I go to divelog directory in MSDOS prompt that now shows
C:\Divelog>
If I compile divelog.java with the command:
javac -classpath c:\ Divelog.java
I receive the errors above.
I moved the files to c:\divelog\images and then tried
C:\Divelog\Images>javac -classpath c:\divelog Divelog.java
but it was useless.
Please help.

Thanks, it worked!
But now when I enter the command
java -classpath c:\ divelog.Divelod
these errors appear:

When i run the "asant build" command in
"c:\java\j2eetutorial\examples\web\bookstore1"
directory i get compile error with last few lines as
follows.Did you package the bookstore common files as described in Chapter 3? My guess is that you didn't include bookstore.jar from <INSTALL>/j2eetutorial14/examples/build/web/bookstore/dist/.

Can anyone help me out as I have tried several books which conveniently skip the part about compiling errors.
I noticed I don't have a CLASSPATH variable and then i created one with just '.' in it and that didn't work. any help would be appreciated as this is driving me crazy. Thanks.

duh !!! I should have just read your error message... its missing or has too many "}" braces... Like the tutorial said, errors are your friends...
You will find it... I think it was done deliberately to get you used to detecting and fixing errors...

No. of Vowels in an user input sentence - Compilation Error

I tried the following program to find the number of vowels in a given sentence :
//Number of vowels in a given line
import java.util.Scanner;
class vowels
public static void main(String args[])
    int a,b,y=0;
    String x;
    Scanner inpt = new Scanner(System.in);
    System.out.println("Enter a line of text to find out the number of vowels in it");
    x = inpt.nextLine();
    char[] c = x.toCharArray();
    b = c.length;
    for(a=1;a<=b;a++)
        if(c[a]=='a'||c[a]=='e'||c[a]=='i'||c[a]=='o'||c[a]=='u')
            y++;
    System.out.println("The numbner of vowels in the given line of text is :" + y);
}But when I run the program, I get the following output :

It's not a compilation error; it's a runtime error.
The error message is telling you exactly what's wrong.
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 8
at vowels.main(vowels.java:16)At line 16 of vowels.java, you're trying to access the 9th element (index 8) of an array that has at most 8 elements (at indices 0..7).

Compiler error using compareTo

I get a compiler error when I use compareTo with the Character class. I confirmed the error with following code from The Java Tutorial:
public class CharacterDemo {
public static void main(String args[]) {
Character a = new Character('a');
Character a2 = new Character('a');
Character b = new Character('b');
// ******* Problem is here ************
int difference = a.compareTo(b);
if (difference == 0) {
System.out.println("a is equal to b.");
} else if (difference < 0) {
System.out.println("a is less than b.");
} else if (difference > 0) {
System.out.println("a is greater than b.");
System.out.println("a is "
+ ((a.equals(a2)) ? "equal" : "not equal")
+ " to a2.");
System.out.println("The character " + a.toString() + " is "
+ (Character.isUpperCase(a.charValue()) ? "upper" : "lower")
+ "case.");
The compilier is complaining that compareTo is not part of the Character class. I am compiling with whatever compilier was installed with Suse Linux 7.1. The code compiles fine on my university's Unix system that I can dial into.
I figure my Linux version must have some old compiler. But to be honest, I am also new to Linux and am having trouble figuring out what I am compiling with. Can any expert out there give me advice on identifying/updating the Java technology I am using. Thanks in advance.
Jim

Check the jdk version using the java command:
java -versionwhich will output the jdk version you're using.

The compile is successful, and we can view the output.
Note that the project is under SVN (Tortoise). It does not
generate the errors when compiled on the machine where it resides.
The errors come when compiling from the other machine.
Can anyone tell me the source of these errors?

Hello Dan,
The phrase "Template Error: can not resolve macro:" tells me
that you are using a template, which means that you are likely
generating printed or PDF output. Is this correct?
Can you generate printed output from this computer manually?
Has Microsoft Word been launched on this computer?
Are the macros setup in MS Word set high? You may consider
lowering it some.
If these steps do not help narrow down the issue some, you
might consider renaming normal.dot. You can look on Microsoft's web
site for details on how to do this:

I have exactly the same error.
Me too, I'm running on Win XP. And I have had lots of trouble to deploy the converter.
I cannot install J2EE 1.3 as I am supposed to write a report on how Web Services may help my company. By the moment I can only say it takes me much more time than expected to run the J2EE 1.3 tutorial. As SUN didn't deliver a tutorial one can use.
So by the moment if anyone can HELP me to finish this converter tutorial I will be thankful.

Got compilation error about 'create instance activity' using file adapter

Hi,
I am creating a very simple bpel process using file adapter. in my 'Receive' activity, I selected 'create instance' , as the tutorial says.
I got this compilation error during deploying.
'Error(31): [Error ORABPEL-10051]: multiple create instance activity [Description]: in line 31 of "D:\OraBPELPM_1\integration\jdev\jdev\mywork\BPELPractices\FileAdapterTest2\FileAdapterTest2.bpel", Conflicting createInstacne="yes". Instance is already created by another activity. [Potential fix]: Remove createInstance="yes" attribute from this activity. '
Several people had the same problem in my team. I wonder if this is a common issue. how to fix it?
Thanks,
Kate

You must be having another receive/pick activity within the same process that has "createInstance" set to yes.
Thats why its complaining.

Applet compilation error

New to java, struggling along... I am trying to make the following applet, it wont compile, likely due to an error in syntax somewhere. Can anyone take a look at this and point it out?
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import java.applet.Applet;
import java.awt.Graphics;
public class MailExample5 extends Applet {
public void start () {
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", "mail.axess.com");
// Get session
Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress("[email protected]"));
// Set the to address
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("[email protected]"));
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
The compilation errors I get are;
- 7 errors
- "unreported exception javax.mail..."; all 7 errors are the same beginning description

I read the tutorial, my understanding of exceptions is that they detect areas in which the program runs into a problem, then figure out what to do with the problem from there depending on where the exception occured.
Unfortunately in the program above, the exceptions are occuring during compilation and not the actual running of the applet (I cant run it if I cant compile it). Even if I "catch" the exception, and am told where the exception is happening in such a small program, I dont know what the problem with the program is to correct it.

Occasional compiler error when cloning

Hi,
I believe I have written all my clone() methods correctly now (thanks guys) and I see this error with only two of the many clone() calls I make. Every other clone() call compiles fine. I was hoping someone might have a hint for me.

    NbrInfo ni    = (NbrInfo)super.clone(); //ok
    ni.id              = (IPaddress)id.clone(); //ok
    ni.policy1    = (Rule)policy1.clone(); //compiler error
    ni.policy2    = (Rule)policy2.clone(); //compiler error
    return ni;
}I don't understand why cloning the id variable works but cloning the policy variables don't. Here are the two classes in question (unrelated stuff left out):
public class IPaddress implements Cloneable {
// ........................ member data .......................... //
/** The actual IP address. */
public String ip_address;
protected Object clone() {
    IPaddress ip_addr = (IPaddress)super.clone();
    return ip_addr; //Strings are immutable, so we don't do a deep copy on them
} // end of class IPaddress
public class Rule implements Cloneable {
// ........................ member data .......................... //
/** The predicates that make up the rule. They will be Strings.*/
private ArrayList predicates = new ArrayList();
// ----- Rule.clone() -----------------------------------------------------//
protected Object clone() {
    Rule r = (Rule)super.clone();
    r.predicates = (ArrayList)predicates.clone();
    return r;
} // end of class RuleThere are other places in my code where I clone() other classes as well, and they are written like I have for IPaddress and they also compile fine. It is just this Rule class that doesn't seem to work right, even though, to me, it looks like I did it exactly like I did the IPaddress class.
Here is the error message:
NbrInfo.java [150] clone() has protected access in Rule
Thanks.

Isn't the stmt where you attempt to clone ArrayList
generating a compiler error? Container classes
don't have public clone methods. You have to construct
an explicit copy for them.Well, the NetBeans compiler points me to the line where NbrInfo is being cloned, but I think it could be what you suggest. Yesterday I was trying to clone ArrayLists elsewhere and got this same problem.
So should I do the bold move of putting the keyword "new" in the Rule.clone() method? Something like:
// ----- Rule.clone() -----------------------------------------------------//
protected Object clone() {
    Rule r = (Rule)super.clone();
    r.predicates = new ArrayList(predicates);
    return r;
}It's just that I found a tutorial online the other night that seemed pretty against using "new" in clone() methods. I hate to violate and laws Java wants me to obey.

Compilation error while calling static method from another class

Hi,
I am new to Java Programming. I have written two class files Dummy1 and Dummy2.java in the same package Test.
In Dummy1.java I have declared a static final variable and a static method as you can see it below.
package Test;
import java.io.*;
public class Dummy1
public static final int var1= 10;
public static int varDisp(int var2)
return(var1+var2);
This is program is compiling fine.
I have called the static method varDisp from the class Dummy2 and it is as follows
package Test;
import java.io.*;
public class Dummy2
public int var3=15;
public int test=0;
test+=Dummy1.varDisp(var3);
and when i compile Dummy2.java, there is a compilation error <identifier > expected.
Please help me in this program.

public class Dummy2
public int var3=15;
public int test=0;
test+=Dummy1.varDisp(var3);
}test+=Dummy1.varDisplay(var3);
must be in a method, it cannot just be out somewhere in the class!
