Import classes from outside

I have a .java file that needs methods from a .class file that is outside of the java SDK environment. I have 3 questions with respect to complie
1. Can I use 'import outside.server.class.*' in my java code?
2. when I javac, how to pass the -classpath parameter? if the .class file is located in a directory (like c:\app\classes\outside\server\?
3. when I execute the final complied .java file, do I still need to pass the classpath again?
thankx
ku

1. yes, you can do this, as long as you have a chain of directories matching your import statement descending from one of the directories in your classpath
2. if, let's suppose, you're in the app directory, you can say '-classpath classes' which should then put your classes directory into the search tree.
3. Normally, yes.

Weird Can not access class from outside package problem

Hi, I have this problem and it seems the error message is very clear what the problem is but I did make the GeneralTestResult class PUBLIC already. What could be wrong? I did search for it but this is too general and didn't find any solution. Anyone can point out the problem? TIA.
public abstract class GeneralTestResult
public static int FAILING_THRESHOLE = 25;
public abstract String getTestName();
public abstract boolean isPassed();
public abstract int getLeftEyeResult();
public abstract int getRightEyeResult();
public abstract Calendar getTestDate();
// in a different file
package VisionSaver.Tests.TestResults;
import java.util.*;
public class AcuityORContrastTestResult extends GeneralTestResult
private String m_testName;
private int m_leftEyeVision, m_rightEyeVision;
private Calendar m_testDate;
// in a different file
package VisionSaver.Tests;
import VisionSaver.Tests.TestResults.*;
public class Acuity extends VirtualKeyboard implements ActionListener, Runnable, WindowListener
AcuityORContrastTestResult r = new AcuityORContrastTestResult(...);
}The compiling error is:
"Acuity.java": GeneralTestResult() in VisionSaver.Tests.TestResults.GeneralTestResult is not defined in a public class or interface; cannot be accessed from outside package at line 529, column 40

The GeneralTestResult class is a packaged class. Sorry, when I cut and paste, I didn't copy everything. So here is the complete GeneralTestResult file:
package VisionSaver.Tests.TestResults;
import java.util.*;
public abstract class GeneralTestResult
public static int FAILING_THRESHOLE = 25;
public abstract String getTestName();
public abstract boolean isPassed();
public abstract int getLeftEyeResult();
public abstract int getRightEyeResult();
public abstract Calendar getTestDate();
}From the compiler's message, it seems like the import is OK. It just won't allow me to access non-public class but my classes here are declared public. Any other ideas? TIA

Importing class from different directory

Hi, Can anyone tell me how to import a class from a different directory? I have a DGenerator class in ./generator directory.
I have tried Import generator.DGenerator; to use the DGenerator class. However. I got the error:
cannot access generator.DGenerator
bad class file: ./generator/DGenerator.class
class file contains wrong class: DGenerator
Please remove or make sure it appears in the correct subdirectory of the classpath.
Help please.
Thank you!

I don't understand why this is a Swing question, but at any rate if you want your DGenerator class to be found in a particular directory, you must do one of two things:
1. Put that directory in your classpath and just refer to the class as DGenerator.
2. Make the class belong to the package "generator".

Can't import class from SWC

I have created a swc file. I can import most of the classes from it in my project, no problem. One class, though, simply won't import. I've tried copying the swc directly into the project, referring to the source folder of it, etc. No dice. The swc builds just fine so there's no error in the class. The first few lines of the class look like this:
package com.thismoment
import flash.events.Event;
public class TakeEvent extends Event {
I should be able to do import com.thismoment.TakeEvent; right? It doesn't work. I keep getting "1046: Type was not found or was not a compile-time constant: TakeEvent."
How do I find out what's going on? Is there a way to dump out all the classes in a swc?

Jason San Jose wrote:
In package explorer you can expand the SWC under the "Referenced Libraries" node. That will show you the classes in the SWC (except any that or overridden by other SWCs in the library path).
A few more things to check:
- Is build automatically on? Try cleaning the library project?
- Is the class selected in the project properties > flex library build path > classes tab?

What is "package explorer"? I can't find a reference to it in the documentation. I'm using Flex Builder 3 on Mac OS X if it matters.
Build automatically is on. I've cleaned every project multiple times.
I don't have a Flex Library Build Path -> Classes tab. I have a "Flex Build Path" entry in Project Properties, and on the Library Path it shows my library added to Build path libraries, link type: merged into code.

Importing classes from Jar files..?

I've run into a problem that I am having some difficulty solving. I currently trying to port a two part Java UI project from Solaris to Windows. The first is a package of core classes out of which I (successfully) create a jar file. The second is a product-specific package that imports the core classes from the package created in the first. The problem is that the second package fails to build because javac says the package from part one does not exist. Here's what I know:
- This UI (built via a Makefile) builds successfully under Solaris
- The jar file that I created in the first part exists in the appropriate directory.
- When I view the contents of that jar it appears as though everything is there.
- The jar file is appropriately included in the classpath of the second build.
Any suggestions you could provide, or resources you could point me to would be greatly appreciated

jh.jar is a static, 3rd party component. Doesn't seem to be giving me any grief, at least not yet.
Correct on your second point.
This is interesting. When I open my "CoreConsole.jar"
file, I DO NOT see any reference to the
com.emc.avalon.core.server package, only a list of
class files that make up that package. You should see the .class files on the left and the relative path on the right.
Also, all of the class file listings have absolute paths according
to the location on my machine they were built, for example:
m:/xpe/CoreConsole/classes/com/emc/avalon/core/server/MessageLogUtility.class
Is this a problem..?Yes, that should be a relative path, with the first entry being the first name in the package statement. So you should see an entry MessageLogUtility.class, and the path should be com.emc.avalong.core.server.
If you can't see the class that's missing, that would explain why the class loader can't find it, either.

Jikes compiler problem when importing class from a jar

hi everyone,
I'm new there so please excuse me if i post a pb that have been already answered...
I've a pb with jikes that is encountering a problem and so closing when compiling. I use ant to build my project.
In my classpath I have, among others, a jar named 'kepler.jar' in which I use the following class 'WSResult;'
In my java class I have the following import :
'import com._4d.kepler.model.WSResult;'
Do you think it is the character "_" that makes jikes to bug ?
What else can be the problem of not compiling and stopping building the project ?
Thank you very much for your help, looking forward to your answer...!

Editing material is vastly different from just playing it.
With Audio, a player is accessing the actual file on the HDD, and reading the info from there.
The big difference is that with PrE (and PrPro), those files are not being used directly. When Imported, a couple of things happen:
PrE creates links to those files, for later use, when one Exports/Shares
PrE creates "proxy files," to display the Video on the Timeline, based on those links. It also creates proxy files for better display, when one Renders the Timeline, or portions of it.
PrE creates a CFA (Conformed Audio) and a PEK (Waveform Display) file, that are used - the CFA is to allow for critical editing and the PEK is what one sees on the Audio Track. The actual files are NOT directly accessed - only the CFA file.
For a bit more info on Conforming, see this ARTICLE.
Now, there have been some problems reported, where the Audio was Linear PCM/WAV. I do not know what there is about the LPCM, that causes the issue, but the "plain vanilla" PCM/WAV's seem to be trouble-free. I would love to read, from an Adobe employee, or audio engineer, explaining on why there might be issues.
For the red, and as there is some "earthiness" to it, I like the Acacia Carneros Pinot Noir. I pick it up at Costco for about US $22. It has proved to be about the best inexpensive PN, that I have encountered. Another, is the Peachy Canyon Incredible Red, which I have picked up "on sale" for around US $ 9. Their Peachy Canyon East Side Zinfandel, is even better, and I've found it as low as US $ 15. If you can find the Glen Carlou Grand Classique (South Africa), it is about the best cheap Bordeaux Blend, that I have ever found at ~ US $ 12.
Good luck,
Hunt

Importing class from default package of a JAR

I want to create objects of a class contained in a JAR. The JAR has many classes in numerous packages, however the class that I want to use is in the default package. I'm using eclipse and have added the JAR to the build path, but eclipse complains that the class name cannot be resolved. Is there some way to specify an import statement to look in the default package of a particular JAR? Any advice is appreciated.

jg2009 wrote:
I was under the impression that classes without a defined package were technically considered to be part of the so-called default package. But, in answer to your question, yes this class does not appear to part of any package.
Just to provide so additional information, the class that I want to instantiate is an Applet, so it is designed to be called from an html object tag, and have access to all of the other classes in its JAR. There is a system that provides access to underlying data via the following components: html form <-> javascript <-> applet <-> serverlets <-> data
I want to automate certain data operations, but the only way to access the underlying data is via the applet. Am I out of luck, or is there some way that I can instantiate the applet?All jverd said is right, assuming it is your code and you can change it: basically move everything to a package. But I think your problem is that the jar is a 3rd party jar and you cannot change it. If this is the case, you can use the 'default package' (the terminology is correct) by having your own class(es) in the default package or by using reflection (last time I tried reflection would work). Both are rather bad solutions, but if you really, really want...
Note: Java actively discourages the use of the 'default package' and more so recently, this is why I am not even sure that reflection would still work.

How to import classes from an external actionscript file

This is driving me crazy, I've been trying to resolve this on my own for ages, and I've reviewed a lot of different materials, but I still can't seem to just import some external actionscript classes correctly.
I'm using Flash Builder 4 with the Flex 4 SDK on mac osx 10.6
the class I'm trying to import (I'll call it DesiredClass) is in a folder like this
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
within the class itself, the package declaration looks like this (I left all the guts out for clarity):
package com.foreignproject
    import flash.display.Sprite;
    public class DesiredClass extends Sprite
        public function DesiredClass()
I'm working on a totally different actionscript file at
/Users/username/Documents/Adobe Flash Builder 4/TestProject/src/TestProject.as
in this file I try to import the DesiredClass:
package
     import com.foreignproject.DesiredClass;
     import flash.display.Sprite;
     public class TestProject extends Sprite
          public function TestProject()
          var neatClass:DesiredClass = new DesiredClass();
And then I try to add the class I want to the source path.
I've tried adding each folder to the source path separately:
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
/libraries/com/foreignproject/com/foreignproject/DesiredClass.as
If I choose the libraries folder or either of the com folders then an error shows up in theTestProject.as file, saying:
Definition com.foreignproject:DesiredClass could not be found.
But f I choose either of the foreignproject folders then an error shows up in theDesiredClass.as file saying:
a file found in a source-path must have the same package structure 'com.foreignproject', as the definition's package, ".
What am I doing wrong? Please help. I bought a book on actionscript, started doing the flex-in-a-week series, read numerous online discussion boards, and I still can't import these classes.
Thanks in advance.

I don't know if this method is supported anymore but you can give it a try.
If you backed up bookmarks in IE using the following directions, you should be good!
*In IE, "File -> Import and Export -> Export Cookies".
*Open newly exported "cookies.txt" in a text editor and put a period before every line that starts with a domain. So a line starting with <b>altavista.com TRUE / FALSE 1388491200 AV_ALL 1</b> will become <b>.altavista.com TRUE / FALSE 1388491200 AV_ALL 1</b>
*Then, move the "cookies.txt" file to your profile folder.
You can get to the Profile folder two ways
*Help > Troubleshooting Information > Profile Directory > Show Folder
or
*Go to '''about:support''' and click Show Folder next to Profile Directory.

Importing classes from default package

hey all,
I've just started a new job, and find myself having to use a library that is written in the default package. At the moment, this is forcing me to put my classes in the default package whenever I want to use this library.
using a line like:
import RowBean;
I get the following compiler error:
    [javac] C:\work\coyote\src\java\com\sok\coyote\Grievance\GrievanceActionServlet.java:8: '.' expected
    [javac] import RowBean;I've tried classic,modern and jikes - all with the same error.
Eclipse seems to compile this happily, but I've been unable to find what it does to compile it.
any ideas?
cheers

Importing a class from another context?

Hi JSP techies,
Im using RESIN and having a simple problem of figuring out how to import classes from another context, if Im using the right word.
ie.
My .jsp files are under $home/resin/doc/test dir. And in the jsp file, I would like to import a servlet class or a plain java class. But the servlet classes and all other classes are located under $home/resin/webapps/project/WEB-INF/classes/a/b/c
Hence when I say
<% page import="a.b.c.*" %>
I get an error saying "a" not found.
1. When I say "servlet classes are in a different CONTEXT", is that right? or is it just another directory?
2. How can I make the jsp file import the classes from the servlets class path?
Note: Ofcourse, when I copy the package to the
$home/resin/doc/WEB-INF/classes dir, everything works fine. But thats simply not an efficient way to get around. Could anyone clear my doubts on this regd.?
Thanks in advance.
Arun

Oh... I get it now. I'm sorry, I had you poorly misunderstood. You are trying to import servlets from another web app or servlet context. I would suggest you put servlets that are common to all web apps in the system classpath and not tie them to any particular web app. In other words create a package directory structure from the system's root directory or any where outside of any web apps and point the system classpath to the beginning of that directory structure. I have a similar thing going with Tomcat. I have a folder in my root called Java_Class which is in my classpath. I build all common utilities in this directory. So I have a com/craig/web structure that holds my AppServlet which is in package com.craig.web. This servlet is visible to all web apps via the Windows classpath. Servlets particular to an application like say an MusicOrderProcess servlet would reside in a package under the webserverhome/webapps/MusicStore/WEB-INF/classes directory where webserver home is the home directory of the webserver you are using. I've tested this across webservers as well (orionserver and Tomcat) and it works.
From the prompt you include in your posts I am guessing that you are running on UNIX. Move your common servlets out of their respective web apps and into a common directory structure. Configure the UNIX $CLASSPATH (or is it $classpath?) environment variable to point to this sturcture and you'll be on your way!
Post again if you have more questions!

Importing classes in Jsdk 1.4.2

Hi,
I have two swing applications that run perfectly well when compiled and run. But then I am trying to include these two programs as two tabbed panes in a third program.
I try to import classes from the other two programs using a simple import statement. But when I compile it the compiler return an error statement.
I tried putting a package line in both the programs and tried importing it as a package in the third one and it says invalid package name.
Can anybody help.
Thanks in advance.

Error when I import classes using directive JSP page

Hi all!
I have installed JDeveloper 11g (11.1.1.3.0)
My applications are located in the C:\dir (JDEV_USER_DIR = C:\dir)
I Created application "Appliation1". In it i created 2 projects (Project1, in it beans session entity and other java classes; Project2, in it JSP).
I want import classes from Project1 to Project2 using next directive:
<%@ page contentType="text/html;charset=windows-1252"
import="project1.*"%>
so in Project properties of Project2 set the way to classes in Project1.
When i run JSP an error occurred:
Error(4,9): The import project1 cannot be resolved
Maybe i'm not set correctly the way to the classes
Thanks in advance.

angelr, thanks, it helped me)
In jdeveloper 10g i set address in Project Properties->Libraries and Classpath->Add JAR/Directory;
and set the way to my classes;
and it worked.
in the 11 version seems different

Want to import Class Attributes from ERP to PI

Hi all,
I'm publishing Asset Information from SAP to PI to an external system.
The information includes EQUNR,SERNR, TIDNR and Partner information.
In PI I manually defined a DataType in PI of Asset and then created a service definition.
I then generated a proxy in ERP to publish the Asset.
I have generated a class in SE24 ZCL_EQUI and created a publish method which calls the client Proxy and it works fine.
Here is my question
Can you import the data definitions(attributes) of the class into PI (similar to how you can import RFC and idocs)?
The reason I ask is rather than manually definining the message Type in PI it would be much more convenient to import it from the class ZCL_EQUI.
This way the data would have the same types and I could update PI from SAP.
I know this may seem a little backwards but it would be useful in this case(think of it as similar to importing an idoc definition).
One approach I could take is to create a Service Definition for the constructor method (which takes in the Equipment Number and returns all the information). I could then publish that to ESR and import the WSDL into PI and then use the data definitions for the publishing of the equipment. ( a little longwinded but it should work).
However it looks like for creating the service defintion I'd have to create a function module (RFC enabled) which calls the class.
I can't see an easy way to create the service definition straight from the class.
So in summary I suppose I have a couple of questions
1) Is there a way in PI to import data structures from ERP?
2) Is there a way in PI to import attributes from classes?
3) Is there a way to create a service defintion straight from a class (or do you always have to wrap it in a function module)?
4) Is there a way to generate a WSDL from a class?
If you have any links or documentation I should read, please let me know.
Thanks in advance for any help.
Regards,
John

Hi John,
the answer to all your questions is: No.
The idea of PI ESR is having a development point for all interfaces. So if you need a data type in ERP, you should rather define the data type in ESR and generate a structure type in ERP with SPROXY.
