Automatic import statements for jsp's?

Is there a feature in Workshop 9.x's jsp editor that will automatically resolve (or prompt to resolve) classes in use which have not yet been imported into the page? A blue box appeared in 8.x and you could select the class to import, but I'm not finding it in 9.x.

Workshop is based on for JSP editing.

Is there a way to automatically import artwork for music already in librar?

Is there a way to automatically import artwork for music already in library?
I just transferred all my music from a PC into my new mac.
I saw a widget that fetches the album artwork from the web. great fun!!!
Now is there a way to fetch all these artworks automatically.
I did not use istore to buy the music - but imported from my cd collection.
Thanks.
What a great system - simple and no hassles. Thanks Apple. Goodbye PC.

If you are using AlbumArt widget you can do this with the widget interface.

Import statement in JSP

          Hi
          I am maintaining a system done by one of our vendors.
          Application is deployed in WLS 7.0.
          When I imported the Jsp's into my IDE , I got errors where java.util classes are
          used in the JSP's and the import statement is missing.
          Most of the Jsp's are like this,
          It is working fine in the production server.
          In the IDE i am forced to put the import statement and that is what I expect.
          But how can it work in the production server without any issue.
          Can someone advise me on this
          Thanks

<%@page import="java.util.calendar" %>
Oops... forgot the "page" in there ...That's what I get for using GUI's too much!!! :)

Import statement for DateCalculator

Hi
What import statement should I add in my wed dynpro implementation for DateCalculator, I already added
import java.util.Date;

Hi,
If you want to perform some opperation with date in webdynpro,we have to import the some more along with above mentioned.like
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
Thanks,

What is import statement for ?

Hi all,
Sorry for asking a silly question. Since it is a new to java forum I am asking this.
What is happening when an import statement is triggered at compile time and at runtime.
What is the difference/advantages/disadvantages between importing an entire package and importing required classes only.
Is there any size limit on the generated class file.

MONITORING CLASS LOADING AND GARBAGE COLLECTION
Have you ever wondered what classes are loaded when you launch an application or from where the classes are loaded? Have you ever wondered when garbage collection runs or how long it takes? The java command line tool offers several different command line options that you can use to get answers to those questions.
You might already be familiar with a number of command line options available with the java command line tool, such as -cp, -Xms, and -Xmx. The -cp option is used for specifying the classpath. The -Xms and -Xmx options are used to specify the heap size. For example, instead of setting the CLASSPATH environment variable, you can use the -cp option to tell the system to look in a specific directory for necessary class files:
java -cp ExampleDir MyExample
Here, the system will look in the ExampleDir subdirectory for the MyExample.class file and anything else needed besides the system classes. The ExampleDir in the command line tells the system to look only in the ExampleDir directory (assume that it's the parent directory). If MyExample.class is located in the current working directory, the system would not find it.
Two less frequently used command line features report on class loading and garbage collection. The -verbose:class option reports when a class is loaded into the Java virtual machine and from where it came. For instance, if you use the -verbose:class option when loading the SwingSet2 demo that comes with the J2SE 1.4.2 SDK, you get a report on the many different classes that are loaded as part of the demo, such the following two:
java -verbose:class -jar
C:\j2sdk1.4.2\demo\jfc\SwingSet2\SwingSet2.jar
[Loaded FilePreviewer]
[Loaded javax.swing.plaf.TableUI from
C:\j2sdk1.4.2\jre\lib\rt.jar]
The first line indicates that the class came from the main JAR for the demo (assuming it was started with java -jar SwingSet2.jar). The second line indicates that the TableUI class was loaded from the rt.jar file that comes with the runtime located in the c:\j2sdk1.4.2\jre directory. (From there, the rt.jar file is located in the lib subdirectory.) Different implementations of the Java platform can have different formats here. The only requirement is that -verbose:class displays messages as classes get loaded and unloaded.
Let's see when classes are loaded, and how many classes are needed for the following simple program:
public class Sample {
public static void main(String args[]) {
System.out.println("Hello, World");
Compile the Sample class. Then run it with the -verbose:class option enabled:
java -verbose:class Sample
When you run the command, you'll see that this simple program requires the opening of five jar files (such as rt.jar) and the loading of almost 250 classes.
To see an example of a class unloading message, try the -verbose:class command line option with the RunItReload class shown in the August 19, 2003 Tech Tip titled Unloading and Reloading Classes.
The -verbose:gc option reports on each garbage collection event. This includes the time for garbage collection to run, and the before and after heap sizes. This is demonstrated in the following lines:
[GC 27872K->26296K(42216K), 0.0069590 secs]
[GC 28973K->26455K(42216K), 0.0036812 secs]
[GC 29134K->26474K(42216K), 0.0016388 secs]
[GC 29117K->26487K(42216K), 0.0008859 secs]
[GC 29134K->26498K(42216K), 0.0009197 secs]
[GC 29180K->26479K(42216K), 0.0008711 secs]
[GC 29149K->26484K(42216K), 0.0008716 secs]
Like the output for -verbose:class, there is no requirement for output format, and it is subject to change without notice. The "GC" at the beginning indicates what kind of collection occurred. The number before the "->" is the heap occupancy before the collection. The number after the "->" is the heap occupancy after the collection. The number in parentheses is the currently allocated size of the heap. The seconds are the duration of the collection.
This information can be useful in debugging. For example, it could help you determine if garbage collection happened at a critical point in time, and might have caused a program to crash. This sometimes happens when mixing Java and C/C++ code with JNI, especially when there is an underlying bug on the C/C++ code side.
If you're ever curious about why it takes so long for an application to start, or if garbage collection in the middle of an operation appears to cause a problem, be sure to try out these command line options.
hope it helps

Why the need of "import" statements for Java base code?

If for documentation purposes, a compiler option to produce an "import list" would have been sufficient.

import statements act as really simple namespaces.
Instead of the programer having to specify:
java.io.File f = new java.io.File("c:\\");
the code can have a 'namespace' added to do the following:
import java.io.file;
File f = new File("c:\\);
it's a way of getting around similiarly named classes, but still have the ability to drop the 'java.io.' part.

Problem with import statement for user created classe

I recently downloaded J2sdk1.4.0_03 before that I had jdk1.3 and never had this problem.All the files other than named package I import for my
application does not compile.But when I commented that out it work just fine.
any help is appreciated

thanks
It makes sense not to import non-packaged class.
My other problem is with JDBC ODBC.I have a Dell system with Windows XP.
I registered my User Data Source to ODBC with MS Text driver(.txt , csv).When the code reaches at the .executeUpdate(CREAT TABLE CUSTOMERS)
it throws an exception
sQLException 3:java.sql.SQLException: [Microsoft][ODBC Text Driver] Cannot modify the design of table 'CUSTOMERS'. It is in a read-only database.
Do I really need to change the attribues or some thing else.
How can I chane the attributes of the database.Never had problem with windows 98.

Automatic imports for javafx files?

I've been using the Netbeans JavaFX plugin for the past few days. I can't figure out how to get Netbeans to add necessary import statements to JavaFX files like it does with normal Java classes. For example, I in the following simple fx file, I need an import statement for javafx.ui.* or javafx.ui.Frame. In a regular Java file, I just press Ctrl+Shift+I and the import statements are added for me. Is this feature not available for JavaFX files?
package timetracker;
//import javafx.ui.*;
import javafx.scene.geometry.*;
* @author allanbond
Frame {
    title: "Howdy Doody"
    height: 400
    width: 600
    background: Color.BLUE
    visible: true
    content: Panel {
}

This feature is not implemented yet. See [125014|http://www.netbeans.org/issues/show_bug.cgi?id=125014] Fix imports feature.
You can use the [JavaFX API|http://openjfx.java.sun.com/current-build/doc/api/index.html] and palette in NetBeans now.

How to organize the import statements in FXML Files?

Hello,
I'm a user of NetBeans IDE and it can organize the import statements in *.java files. Now, I'm using JavaFX and editing the *.fxml files as well. I want to know how to organize the import statements in *.fxml files?
Thanks a lot.

You should use Scene Builder, it will make all these import statements for you.
Moreover, it will greatly simplify the writing of your FXML files, since you only have to Drag&Drop JavaFX objects on the scene. Then, it automatically generates FXML files.

Javac(1.4.2) gives error in import statement

Hi All,
I am facing a surprising problem. I have 2 java class files. I write the import statement for second one in the first one. There is no package & these are in the same directory. I have compiled the second one. But when I try to compile the First one. Javac throws error at import statement like below :
D:\Clubs\oct\6>javac -d . ManojTest.java
ManojTest.java:1: '.' expected
import SessionBean;
^
1 error
My Java Files are as below :
import SessionBean;
public class ManojTest
public static void main(String args[])
//ManojTest.java
public class SessionBean
public static void main(String args[])
//SessionBean.java
I have compiled SessionBean.java successfully but when I try to compile ManojTest.java I get error mentioned above.
However this probelm comes when I use j2se 1.4.2.. but works in j2se 1.3.1..
Another way could be I use package structure.
But I can't do any of these, as I have to port my big project to j2se1.4.2.. from j2se1.3.1.. (Live project is running on Tomcat).
Problems is similar in Unix & Windows both.
Is this javac compiler issue or there is some setting which I can make.
I have already included . (dot) in PATH & CLASSPATH environment varibales.
Please help me out if there is any way around this, as i am stuck up in between
thank you
Manoj :confused:

Use a package and then add that package in your classpathOr don't use a package, leave the file in the default (noname) package, and don't use the import statement. Java will find it in the default package without the import.
Explicit import statements from the default package are no longer allowed

Import statement *not* required?

Can someone explain this to me? I was following along a
simple AS3 example (in the design video workshop) where a "Power
Button" has some MouseEven CLICK event handling applied to it with
a trace statement as the resulting handled function. Really simple
basic example. The import statement is import
flash.events.MouseEvent.
How come removing the import statement does not produce an
error?
Reference:
import flash.events.MouseEvent;
myButton.addEventListener(MouseEvent.CLICK, myButtonClicked);
function myButtonClicked(event:MouseEvent):void {
trace('do Something');
}

That's a general rule of thumb, but not 100% applicable.

There are exceptions, and the easiest way to find them is to
leave out
your import statements and plug away ... sooner or later,
you'll get a
compiler error, and then you'll know. :)
>> It did strike me *** odd though, an imported .as
file uses the same
>> publish settings as code on the timeline. So why
treat them differently?
FLA files have publish settings, but AS files don't. They're
just text
files. I hear what you're saying ... they end up getting
compiled along
with / into the some FLA anyway -- and that FLA does have
classpaths
listed -- but those same AS files might be compiled in Flex
Builder 2 or
some 3rd party compiler. It would probably make good sense to
require the
import statement for inline FLA code, but not everyone is a
hardcore
programmer, and Adobe knows it. Nothing is *hurt* by using
import in FLAs,
but for folks who just want to do light programming, the
convenience of not
having to use it is nice.

Variable within an import statement

I'm wanting to have a variable in an import statement for different versions of a class
example - import someclass.VERSION.*;
but I want VERSION to be a variable that I can modify for every project that uses the class I'm importing from. I have not found any examples that have done this thus far.

The point of my suggestion was that it would make it unnecessary to change anything at all for compiling different versions.
make 3
Making version 3.0 <<<See how easy that can be? Reading the version of the class to load from an external class file and dynamically loading it is tantamount to a Rube Goldberg machine. Also, you still have to change a file, your properties file. If your project grows to any significant size, this approach will cause you serious headaches.

Auto-organization of import statements broken

Anyone else having this problem?
it happens pretty regularly, when I use auto-complete on a new object type, then flexbuilder goes and totally screws up all my imports, causing me to have to go through and ctrl-space (alt+"/" ) each one.
Also, it seems to never put in the correct import statement for an MXML component that I refer to in my AS block. I finally just used the fully qualified name because I was sick of FlashBuilder removint the import after I added it 5 times.

Known bug http://bugs.adobe.com/jira/browse/FB-23179 or one of the related bugs.
