Hi.
Please always state the JDev version you use when you ask a question.
What do you mean exactly by cleanup? From the look of it, either you changed the package declaration at the top of you Java files for something that doesn't exist or renamed the on-disk directories in the package structure to something that doesn't match the package declarations in your code.
Do not forget there is a direct correlation between packages names and directories.
So, if you have package
com.oracle.blueberryYou will have the following on the disk:
src\com\oracle\blueberryBest Regards,
Frédéric.

• Jdeveloper 10 to 11g migration package does not exist

Hi All,
I am new to Jdeveloper, earlier I have used eclipse.  We have a web application which was developed using Jdeveloper 10 and now we are in progress of migrating it using  JDeveloper 11g (11.1.1.7.0).
We have two projects(.jpr), lets say A1.jpr and A2.jpr with in the application (.jws) say App.jws. The old source has been migrated in Jdeve 11g using migration wizard successfully.
In project A1,  a class from project A2 has been imported, Which was not able to recognized and I'm getting numerous errors when the A1.jpr was build.
Note:The same code compiles without any error in Jdeveloper 10
D:\Migration\App\src\test\pack\util\entities\UserImp.java
Error(3,18): package com.util.permission does not exist
Error(6,25): package com.util.domain does not exist
Error(29,20): cannot find class domain
Error(38,32): cannot find class permission
It would be great if anyone could help me on this.

Where those classes/packages resides ?
Inside some .jar ?
In tht case, add that .jar to the project Libraries and classpath.
Right click on the ptoject, choose 'Libraries and classpath' and Add jar/directory to the project...

• Compiler exception - package does not exist?

I am new to NWDS and J2EE.  I followed the steps in the tutorial as indicated in the below link:

I did everything inside up to the last moment after I deployed my EAR and tried to run from the portal but got Application error.  I checked the defaultTrace log file from the portal server and notice these errors:

The thing I don't understand is the "comp.sap.examples.calculator.beans" class has already been included inside the EAR (I used my zip tool to check the EAR file and confirmed it's there), why did the compiler still complain that the package does not exist?  Any great guys & gals out there can help this poor newbie who spent the past 5 hours searching for Google for answers but couldn't find any??
Thank you.
Brian

The EAR file contains a WAR file and a JAR file.
The WAR file contains a JSP and it contains codes to refer to a java proxy class of package comp.sap.examples.calculator.beans.CalcProxy.
So it seems the compilation error is triggered when it tries to compile the WAR file.
I checked the structure of the WAR file using a zip tool.
At the base it contains this:
WEB-INF (a folder)
Calculator.jsp (the JSP file)
Inside the WEB-INF folder is these:
classes (a folder)
web-j2ee-engine.xml
web.xml
Inside the classes folder is a tree of subfolders to describe the structure of the CalcProxy class:
classes -> comp -> sap -> examples -> calculator -> beans -> CalcProxy.class
So the java class file and the JSP file is in the same bundle of the WAR file.
Why the compiler is not able to find the class file inside the JSP?

• Package does not exist problem

Hello everyone:
I am a very new programmer student, and I'm having a problem I cannot seem to resolve. I am setting up a method for a JButton, and with the first inputs I'm getting a package does not exist error. Here is the code in question:
private void placeOrderJButtonActionPerformed( ActionEvent event )
double subtotal = 0.00;
// calculate subtotal
if ( hamburgerJRadioButton.isSelected() )
subtotal += 6.95;
else if ( pizzaJRadioButton.isSelected() )
subtotal += 5.95;
else
subtotal += 4.95;
// declare display format
DecimalFormat dollars = new DecimalFormat( "$0.00" ); // display subtotal subtotalJTextField.setText( dollars.format( subtotal ) ); It is coming back with these errors: C:\Users\Brian\Desktop\LunchOrderForm.java:255: <identifier> expected subtotalJTextField.setText( dollars.format( subtotal ) ); ^ C:\Users\Brian\Desktop\LunchOrderForm.java:255: package subtotalJTextField does not exist subtotalJTextField.setText( dollars.format( subtotal ) ); I declared subtotalJTextField as an instance variable, but I'm not sure what its telling me here. Could anyone help? When you post code, click on the "code" label and paste the code between the code tags. rnashting wrote: // display subtotal subtotalJTextField.setText( dollars.format( subtotal ) ); It is coming back with these errors: C:\Users\Brian\Desktop\LunchOrderForm.java:255: <identifier> expected subtotalJTextField.setText( dollars.format( subtotal ) ); ^It appears that the line with the error is not inside a method. Java does not allow you to write code like this outside a method (or an initializer block). C:\Users\Brian\Desktop\LunchOrderForm.java:255: package subtotalJTextField does not exist subtotalJTextField.setText( dollars.format( subtotal ) ); I declared subtotalJTextField as an instance variable, but I'm not sure what its telling me here. Could anyone help?I can't tell from the code you posted where this problem is. You most likely have not declared subtotJTextField correctly. • Package does not exist when compile in Jgrasp 1.8.3 I have a package called jpb stored in a folder called jpb. The package has two files SimpleIO.java and Convert.java. My program has 1 of the line like this import jpb.*; I put the path and classpath in Jgraps pointing to the folder jpb but when I compile the program, it keeps saying the package does not exist. Even when i took all the files outside and place it in the same folder with the file that i am compiling. It says that bad class file. The heck?????????. Can some1 please help. I even made an autoexec.bat to set up the path to the folder and run it. it keeps saying the package does not exist. Classpaths reference things like jar files or directories that contain .class files. Change your classpath to have the .jar files. • Import statement reports 'package does not exist' I am seeing another odd error.

First of all I have the 'main' source file under a directory: d:\Model1_SecurityService\ There is a subdirectory securityservice, under which there are several other directories according to the packages I have. Another directory I have is: d:\Model1_Classes When I compile the main program from d:\Model1_SecurityService> typing the following: javac -d d:\Model1_Classes testmain.java When I do this, i get an error message saying package does not exist for each package I import in the main file. My classpath has d:\Model1_Classes in it and my path has .; etc. Anyone know what the problem is? Everything used to work but i continued working on another computer and after copying these changes to this one, i'm getting these errors... So, for example if you had a class Baz in package com.foo.bar and you're using d:\Model1_Classes as your root directory for your compiled code, then there should be a directory structure d:\Model1_Classes\com\foo\bar which contains the compiled class Baz.class. Is this what you have?yes I found the problem though, apperently i need . in my classpath as well; don't know why actually, but it works now. thanks for wanting to help though • Java.math package does not exist!!! hi java experts, i really desperately need some help. ihave been trying to compile a java program i have written that imports the java.math package as i am using the BigInteger class. I am using SUN ONE STUDIO ME 4 and have j2se SDk installed. when i try to build the program in the IDE, it gives me an error message saying the java.math package does not exist. i can't understand why. i think it's an IDE problem. i tried mounting the filesystem and i mounted almost a million times in diff ways but it still can't compile. i can't find the directory of the java.math to mount into. anyway i tried to compile it at the command prompt and it can compile but with errors... so i figure that i do have the java.math class on my system just that the IDE jsut can't recognise it. i am at my wits end and gonna go mad if someone doesn't please help me. adeline from singapore Cross-posted at http://forum.java.sun.com/thread.jsp?thread=293132&forum=54&message=1155073 • Import javax.mail package does not exists Hi, when i tried to compile the source code for email using jdk1.3.1, it compiled fine. but when i tried to compile using jdk1.4.., it had the following errors such as import javax.mail package does not exists, import javax.mail.internet package does not exists package javax.activation does not exist Is it because of the jdk version problem???

for example, i want to use the class
org.apache.tomcat.core.Context to create a class

import org.apache.tomcat.core.Context;
-or-
import org.apache.tomcat.core.*;
Note how that is different than your original:
import org.apache.tomcat.*;i just use as an example import org.apache.tomcat
but i cannot find org.apache.tomcat.core or even any org.apache.tomcat.*
so that means i havn't include the correct jar file in the classpath or no corresponding package are stored in the tomcat4.1
i just want to know what jar file contains such stuff.
i think it should be a silly problem. So there should be someone know it.

• FTPClient Package does not exist?

I have an FTP program. I'm trying to use this package. Here is a link to the class package overview:
When I attempt to compile, I get the error that the package does not exist. I am importing these packages:

import java.lang.*;
// This package causes the error
import com.enterprisedt.net.ftp.FTPClient.*;
Is there something I need to download, or some other package to import?
Thanks,

Hi,
I finally found the ftp.jar and downloaded it and put it in the /j2se/jre/lib/ext.
I can now compile with this import line:
import com.enterprisedt.net.ftp.*;
Now my problem is trying to get this to work:
String server = "192.168.1.100";
String user = "logan";
String passwd = "passwd";
try {
FTPClient ftp = new FTPClient(server);
} catch (IOException ex) {
System.out.println("Caught exception: "+ex.getMessage());
But I get this error when compiling:

• Error:  microedition.io.* package does not exists

Been at this for a few days...frustration...funny.
Using JDK 1.6 NetBeant 6.8 with WTK 2.5.2 on XP
Was able to resolve the javax.bluetooth.* package does not exists and xylostudio by doing the following to add the libraries to the project file.
1) Tools > Libraries
2) in the pop up Library Manager window click 'New Library'
3) in the pop up New Library window typed 'bluetooth' > OK
3) highlight 'bluetooth' in Library Manager scroll menu on left
4) click add JAR/Folder
5) added jsr082 from C;\WTK2.5.2_01\lib\jsr082.jar
6) click OK
7) right click project and select properites
8) highlight the library node under Categories on the left side of the Project Properties window
9) 'Add Library' created 'bluetooth'
10) click OK
When the process was followed to resolve the microedition.io.* package does not exist error it was unsuccessful.
The difference in the two processes being New Library name: 'microedition' and added jsr75, MIDPapi20, jsr118, then MIDPapi21 with no resolution to the errors.
Also add the jsr75, MIDPapi20, jsr118, and MIDPapi21 directly to the project by clicking the 'Add JAR/Folder' button in the Project Properties window.

By completing the process shown in below link and adding the bluecove jar file directly to the project as of the reply post suggests, all compilation errors were corrected.

• Package does not exist error-message

When I try to compile a java servlet with the following piece of code I get a compilation error referring to the import statement.
I have just included the initial import statements. A large number of errors follow, as a result of this 'package does not exist error-message'.
Has anyone encountered this or any ideas?
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.* ;
import java.io.* ;
import java.sql.* ;
import com.ericsson.snf.mps.mppapi.mtlr.*;
The error messages come from the 'import com.ericsson.snf.........' statement.
I am trying to integrate ericsson software, into my application.
Thanks,

That's probably because you are trying to integrate j2me suff with j2se/ee. That won't work without los of extra work..

• Imported package does not exist

Hello
I'm importing a package com.borland.jbcl.layout.* into my java
program to do some GUI layout but kept getting the error that the package does not exist. Can someone explain why and the solution to this problem please?
Thanks
Danny

If the class you are trying to import is in a .jar file, you need to add the jar to your classpath CLASSPATH=c:\dir1\...\MyJar.jar. If the file is in a directory you need to include the base directory in the classpath CLASSPATH=c:\basedir
