Tutorial 7 - Compile errors

BUILD FAILED: C:\medrec_tutorial\src\physicianEar\mybuild.xml:7: Could not create
task or type of type: wlcompile.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'wlcompile'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
libraries were not found at build time.
Fix: look in the JAR to verify, then rebuild with the needed
libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

Hey Kaven. The Ant task "wlcompile" is a custom Ant task provided within the WebLogic 8.1 distribution. If you use the set environment scripts within the distribution, the distribution's Ant script will be used and all the necessary jars will be added to your classpath. The class WLCompileTask is packaged in weblogic.jar.

"asant build" for bookstore1 example in j2ee tutorial gives "compile error"

Hello everybody,
I am trying to run "asant build" command to build package for bookstore1 example given in j2ee tutorials.
I installed my j2ee tutorial 1.4 in "c:\java\j2eetutorial14" and my example is in "c:\java\j2eetutorial\examples\web\bookstore1".
My j2ee SDK with appliation server is installed in C:\sun\appserver.
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.

Can some one please help me.

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/.

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 :
Enter a line of text to find out the number of vowels in it
Honduras

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.

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

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.
Bye

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.
//the class is called NbrInfo and id, policy1, policy2 are its member vars
// ----- NbrInfo.clone -----------------------------------------------------//
protected Object clone() {
    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!

Compile Error: "schema 'name' does not exist

Im trying to build a program that quereys a table in a database but i keep getting this error. Am i missing a link between the files or am i missing a line of code in my program??

Apologies. I receive a compiler error which reads as follows;
java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
java.sql.SQLSyntaxErrorException: Schema 'DEMO' does not exist
Heres the main body of code i am trying to execute.
public class Main {
* @param args the command line arguments
public static void main(String[] args) {
// TODO code application logic here
try{
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
}catch(ClassNotFoundException e){
System.out.println(e);
try{
Connection con = DriverManager.getConnection("jdbc:derby://localhost:1527/SimpleDBDemo", "demo", "demo");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM DEMO.Table1");
while (rs.next()) {
String s = rs.getString("Name");
float n = rs.getFloat("Age");
System.out.println(s + " " + n);
}catch(SQLException e){
System.err.println(e);
I am using NetBeans IDE and have created a database under: Services->Databases-> Java DB->SimpleDBDemo.
I have a database connection in which theres a simple table (called "TABLE1") created which contains the names and ages of two people.
Hope this makes the problem a bit clearer.
Any help would be greatly appreciated.

I would appreciate any help in trying to resolve this compilation error so that I can proceed with implementing LDAP features for this endeavor.

PL/SQL Procedure Compilation error

Hi,
 
I have wrote a PL/SQL Stored Procedure to read a couple of table values and then output some data to a file, when I create the procedure on the database I get the following compilation error:

Can't Export Movie - Unknown Compile Error - Help!

I edited a 32 minute movie in Premiere Elements 10, and now I'm trying to export it. At some point during the export, and it seems to vary, I get an unknown compile error. I've been trying to export the movie for the past week and all I get is failure despite trying just about everything I've found written about how to solve this.
I have Win 7 Ultimate SP 1 running on a Lenovo desktop machine with an Intel Core 2 Quad CPU at 2.67 GHz, 4GB of RAM, 32 bit proc.
Premiere is installed on system C drive with 6 GB of free space.
Project and scrach disks are on D drive with 165 GB of free space.
Media files are on 2nd E drive with 50GB of free space.
Project and most source material is NTSC DV -- there are quite a few photos with motion, plus some iPhone HD video on the timeline, hundreds of clips in all plus narration, a few titles, etc.
Export destination folder is on D drive.
Everything will render to green lines atop timeline (sometimes it quits during render and I have to keep hitting Enter to continue rendering, but eventually it's all green)
So far I've tried:
- Reinstalling PE 10
- Reinstalling Quicktime
- Copying all the photos to their own separate folder
- Editing each photo slightly (outside of PE 10) and resaving to make sure none of the photos are corrupted
- Emptying the temp folder
- Deleting all the renders and cache files and letting them rebuild
- Exporting small pieces of the timeline to try to identify a bad clip -- this is a maddening process and I did find one clip that would generate the error, but I managed to export that to AVI and reimport and replace on timeline. It would be awfully nice if PE would just TELL ME which clip it doesn't like if in fact it's a clip error.
- Turning off the shadow / highlight feature I had on some clips, but this wasn't the issue, smaller sections with these clips exported fine
- Tried exporting to various formats: Vimeo SD, MPEG DV Standard, iPad Standard High Quality, AVI -- all result in the same error (the format I want by the way is Vimeo SD)
- Rebooting the machine and turning everything off that might possibly consume memory
This machine has never had problems exporting in the past. One thing I did try that worked -- installed PE 10 on another (less capable) Win 7 machine, and fed it all the media via an external drive. The other machine did the export fine (though it took a while given it is underpowered). This is nothing more than a work around though as I don't normally have access to this machine and I'm not done editing.
I'm at my wits' end! What else can I do to get this movie file to export?
Appreciate any help or clues you can provide to solve this mystery.

Oh, that is tragic!
I never had any issues with mine. Maybe it knew how respectful I was, having come from manual rewinds and a sync block? The Moviola was a godsend, at least for me. I am glad that I got to edit film, and on many setups, as some of that translated well to digital Video. Back when I was in film school, Video was 2" tape, and the only editing was by cutting at a 45 degree angle, and splicing the tape. There was not even deck-to-deck editing, way back then. Also, Video looked like crap, at least to my eyes. We could only use a switcher, to "edit," or do a feed to air. Looked like crap!
As for the Lexus, I can imagine all sorts of problems. My new LX-570 requires me to "Accept," when I put it into reverse, on the rear-view monitor! At least my wife's MB does not require that, but it is a 2011 model, so maybe the 2013 models will require that the user sign off on all sorts of "stuff."
Now, I can play Finding Nemo, for my rear-seat passengers, while driving, but the front-seat passengers cannot see it, which is just fine. When driving, I am not even a fan of hands-free calls, and declined most of the streaming stock quotes, etc. for XM/Sirius radio. NOT while I am driving. I will save that for reading the WSJ in the club at the airport.
Some years ago, our driver in London got a new BMW 7-series, and it allowed the playing of DVD's, even in the front, while driving. Not sure that I would want that, but such is life. At least his seats' ventilation system was "well-chilled," where ours' are just air. He almost froze my bum, showing off his new auto.
Now, working with PS, or PrE in an auto, or even on a mobile device, is just not something that I can wrap my old head around. I want a fast computer, with a big display, and cannot imagine editing Images, or Video, on any handheld (or auto) device.
