Applets: location of class files

Can applets use classes from a directory other than the one holding the applet?
I want to have some common classes used by applets that are scattered about in different directories. Anyone know if this is possible?

I would assume it would be possible but you would have to set your class path to point to those directories containg the class file. If you are using eclipse a good idea is to put all of those class files that will be used more then once into one project (a util project) then when you create a new project just have the new project reference the util project. Then when you go to create the jar for you applet it will create it will all of the class files used in the util project as well as all the referenced class files in the new project.
Just ideas..... hope they help

did you create the Searcher class? if so stick it in a package and put it under your web-inf directory. then use an <%@ page import="" %> statement to import the code.
if you didn't create the class is it in some jar library you downloaded? if so stick the jar file in your web-inf/lib folder.

Location for class files for the custom application

Hello everyone.
I want to create new custom application with the short name as "myapp". According to convention what should be the namespace? Should it be mycompany.app.myapp or should it have oracle somewhere in the namespace?
- Yora

Hi Yora,
Package Structure for Standard Application like below
oracle.apps.myapp.webui //Structure for Page and Region.xml(PG.xml,RN.xml,CO.class)
oracle.apps.myapp.server //Structure for .class files(VO,AM)
Package Structure for custom Application like below
mycompany.oracle.apps.myapp.webui //Structure for Page and Region.xml
mycompany.oracle.apps.myapp.server //Structure for .class files
Thanks,

How to 'deploy' an Applet when class files are on client machine?

Hi all,
I've searched through these forums and I can't find where my specific question has been asked before, so please accept my apologies for any duplication.
I am trying to develop an applet for use on an intranet. (The specific requirement is that the applet must operate a scanner, and upload the scanned images to the database - we want it to be an applet so that it seamlessly integrates with the rest of the web application from the user's POV).
Therefore the applet needs to run outside of the sandbox, but I don't want to go to all the hassle of getting a certificate from Verisign and signing the applet - that doesn't seem like it should be necessary, since there is no problem getting access to the client PC to install the class files by hand!
I have read on this tutorial page that applets "that are loaded from the local file system (from a directory in the user's CLASSPATH) have none of the restrictions that applets loaded over the network do," so I don't think I am barking up the wrong tree:
http://java.sun.com/docs/books/tutorial/deployment/applet/security.html
That is exactly what I want to do! But whenever I try to run the applet, I get a no class definition found exception. However, if I run the applet as a standalone application (using its static main method) then the JRE has no trouble locating the class file - so I know that my CLASSPATH environment variable is set ok.
Therefore I think the problem must be in my JNLP file. This is what mine looks like at present:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://localhost:8080/JGNS008" href="http://localhost:8080/JGNS008/scanner-applet.jnlp">

        <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" />

         width="72"
         height="20">
     </applet-desc>
     <update check="background"/>
</jnlp>How do I rewrite this so that it doesn't try to download the class files from the network?
Many thanks,
Richard.

Huh. I had never heard of that, but since I do not have access to my end user's classpath it is not that important to me.
BTW - I am guessing they mean the path indicated by [http://pscode.org/prop/all.html?prop=java.class.path].
And putting classes into JRE folders seems very hackish to me.
That is exactly what I want to do! But whenever I try to run the applet, I get a no class definition found exception. However, if I run the applet as a standalone application (using its static main method) then the JRE has no trouble locating the class file - so I know that my CLASSPATH environment variable is set ok.Huh?
Therefore I think the problem must be in my JNLP file. Huh?!? Why not deploy the applet using a standard applet element? The only way to configure an applet using a JNLP is ..
a) If the applet is intended to be free floating.
b) If the applet is intended to be embedded in a plug-in2 architecture JRE. Why impose that restriction, when it seems unnecessary and unproductive?
Note that the second option is very new, and I would not expect all the things mentioned in the document you linked, to apply equally to JNLP embedded applets. If you want this applet embedded, I suggest you drop the entire JNLP approach and use a standard applet element.

Class not found in applet using 2 jar files

I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:
load: class NervousText.class not found.

Call a method of a class file from an Applet

I have an Applet nmaed CountDown.java in which I have to call a method "doSelect" of a class file named DBConnection.java. How do I do this? Both the Applet and the class file are in the same directory.

You should put both classes in the same package and create a jar file containing the whole package.
Make sure the DBConnection class is public or protected and that the method you're trying to call is public or protected.

How to include class files in no package?

hi,
I have a class file in a package called
pack.Test
and a class file not in a package called
Library
When I try to use Library from within pack.Test, it says theres no such class. I have my classpath setup correctly, and the files in the correct directories.
ie. on windows if %DIR% is the base directory then
%DIR%\Library.java
%DIR%\pack\Test.java
is how they are layed out.
Is there a way to get Library imported to pack.Test?
thanks,

What?!! It isn't considered legal to access a
root-level class from a higher level package?Well it's not now because your code won't compile, but
prior to 1.4 you could. I think the JLS has been
updated to say you can't import from the unnamed
namespace.Hmm! I must have missed that bit (not that I read it in any great detail, anyway!). I suppose it forces you to use packages, which is a good thing, IMHO.
What I was wondering about was, is the directory structure of classes strictly necessary, given that a class contains information on its package anyway? I know some IDEs don't require the source files to be in the right directory - they will check on the package statement, and locate the class file accordingly - but is it absolutely necessary for class files to be located according to their directory structure? I know the JLS says they have to be, but could the JLS be relaxed on this point, without breaking anything?

Alternatives to needing class file during deserialization?

Hi,
I'm trying to find a way of deserializing an object without requiring its class file (eg, class A) to be present. In that case the JVM instance that's deserializing an instance of class A wouldn't need to worry about needing to access the class A from its classpath (file "A.class") or from any other source (such as a custom classloader loading class A's bytecodes over the network) in order to deserialize an instance of class A, except when the source is the serialization stream itself -- all data needed for serialization would be contained only within the serialization stream.
I believe this should be doable by first serializing an instance of class java.lang.Class that represents class A (since java.lang.Class instances are serializable), and then serializing the instance of class A, as explained below. This technique isn't working, and I'm wondering if anyone knows why, and if there are other known techniques for accomplishing the same objective.
I start out with these classes as a test that serialization is working:
The class whose instance I'm serializing/deserializing:
class A implements java.io.Serializable {
     public int x = 5;
}Serialization code:
import java.io.*;
class Serialize {
     public static void main(String[] args) throws Exception {
          FileOutputStream fos = new FileOutputStream("a.ser");
          ObjectOutput out = new ObjectOutputStream(fos);
          A aRef = new A();
          out.writeObject(aRef);
          out.flush();
          out.close();
}Deserialization code:
import java.io.*;
class Deserialize {
     public static void main(String[] args) throws Exception {
          FileInputStream fis = new FileInputStream("a.ser");
          ObjectInput in = new ObjectInputStream(fis);
          A aRef = (A)in.readObject();
          in.close();
          System.out.println(aRef.x); //expect 5
}Here's what I do:
(1) javac A.java Serialize.java Deserialize.java
(2) java Serialize
(3) java Deserialize
This works fine, and prints "5" as expected.
Now that I know that this base case works, I next try to serialize an instance of class java.lang.Class into the stream. This instance will represent class A, and can be obtained by specifying the literal "A.class" in the source code as shown below. Then I serialize an instance of class A as before. I'll then repeat step (1) and (2), erase the "A.class" file, and then do step 3. Here's the new code:
The class whose instance I'm serializing/deserializing (same as before):
class A implements java.io.Serializable {
     public int x = 5;
}Serialization code:
import java.io.*;
class Serialize {
     public static void main(String[] args) throws Exception {
          FileOutputStream fos = new FileOutputStream("a.ser");
          ObjectOutput out = new ObjectOutputStream(fos);
          Class clazz = A.class;
          out.writeObject(clazz);
          A aRef = new A();
          out.writeObject(aRef);
          out.flush();
          out.close();
}Deserialization code:
import java.io.*;
class Deserialize {
     public static void main(String[] args) throws Exception {
          FileInputStream fis = new FileInputStream("a.ser");
          ObjectInput in = new ObjectInputStream(fis);
          Class clazz = (Class)in.readObject(); //shouldn't this cause class A to be loaded?
          A aRef = (A)in.readObject();
          in.close();
          System.out.println(aRef.x); //expect "5"
          System.out.println(clazz); //expect "class A"
}And now the revised steps:
(1) javac A.java Serialize.java Deserialize.java
(2) java Serialize
*(3) Delete the "A.class" file because it shouldn't be needed since we're now serializing an instance of class Class that should fully represent class A.*
(4) java Deserialize

        at Deserialize.main(Deserialize.java:6)Why is a ClassNotFoundException thrown? Class A is already loaded automatically after the instance of class Class is deserialized, isn't it? It's possible that an instance of class Class doesn't store method bytecodes -- I'm not sure about that. But even so, I purposefully did not include any methods in class A -- I just made the data member public (bad form, but this is just a test).
Any ideas why this isn't working, or a way(s) to accomplish the goal?
Thanks,
Will

serializing java.lang.Class instance does not really write the content of the class file in to the stream. It only write a class descriptor. At the read end it will try to locate the class file locally and validate the class file with the information in the descriptor.
You need to have mechanism to send the data of the class file itself in to the stream before sending the instance.
take a look at the annotateClass and resolveClass methods in ObjectOutputStream and ObjectInputStream

IE 6 won't locate class file???

Can someone tell me what's going on here:
I've created a simple Hello world applet and compiled it.
When I use the appletviewer to view the html page I've created for it, it works fine, no problems.
However if I try to view it in Internet Explorer, I just get a grey box where my applet should be and and the message "class HelloWorld not found" in the taskbar.
I can't understand why it'll work in the appletviewer and not in Internet Explorer.

<HTML>
<HEAD>
<TITLE>A Simple Program</TITLE>
</HEAD>
<BODY>
Here is the output of my program:
<APPLET CODE="HelloWorld.class" WIDTH=150 HEIGHT=25>
</APPLET>
</BODY>
</HTML>
I don't think it's a problem with the HTML because it if it did, it wouldn't work in the appletviewer either. I think it might have something to do with with how IE locates class files?

I searched for the same and found the following article in many places which doesnt seem to help me much.

Hi Lisan,
Which version are you using? Folder strucure differs for 11i and R12 versions.
All the class files will be placed under the JAVA_TOP folder. From there you have to follow your package structure. Here it is oracle/apps/xxogl/f04/cp/file
HTH,

Include rt.jar class files in my own jar file to run 1.2+ applets on MS JVM

My problem is this. I'm writing an applet (which includes 1.2 classes) for my organization (over 2000 NT workstations) in which no one has administrative privelages to install Sun's JRE 1.2 or greater. The target browser is IE 5. Our NT admins are having problems pushing the JRE out so my only two options are to rewrite everything as 1.1 or somehow include the missing class files from rt.jar.
I really do not want to rewrite it all!
I was able to extract the missing class files (i.e. /java/util/HashMap.class) but I cannot figure out how to get the IE JVM to use them. Things I have tried:
1. jarred up all my class files along with the missing classes from rt.jar.
$ jar cvf test.jar *.class java

RESULT: IE JVM complains classnotfoundexception (its complaining about not finding HashMap.class)
2. Tried to just place missing *.class files in same directory as my class files
RESULT: Compiler error (complaining about file not be in correct path package) I understand this because when it was created the package statement has the class file in java/util/.
If anyone has done this before or knows how to do it, please help me out.
Thanks!

When the collection classes first came out, I think they were available in a separate jar (although the package name may be slightly different). If it's just collection classes, that might be worthwhile looking at.
The MS JVM may be spewing because the class format is too new; you may try with rt.jar classes from an older JVM (such as JDK 1.2), or try to recompile them from source using -target 1.1.

In PI 7.1 - Java UDF's Compiled Class files - Jar File location

Hi All,
In PI 7.1 Does anybody know where the compiled Java UDF's (which are used in Graphical mapping) class files stored in jar are located in integration server? I want to use this jar file in my XSLT mapping.

Hi,
I guess it would be under
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\temp\classpath_resolver
or
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\.\temp\classpath_resolver
Where SID is your XI instance name.
Thanks,
Gujjeti

Java .class files - Moving the Main Class .class file to a new location

Novice question....so much so that I hope it's even coherent...
In a Java program which references many associated .class files (e.g. bicycleMain.class, bicycleSub1.class, bicycleSub2.class, etc....), do the associated .class files always have to be located in the same directory as the Main .class file?
What I'm getting at is - If I've developed an application consisting of several .class files on my own Windows PC and I want to put the compiled application out on our Windows File Server so that anyone can execute my application, how would I go about doing this?
Say I put the compiled .class files in H:\PROJECTS\JAVA\COMPILED\, will other people be able to execute the application from their PCs by simply issuing the command line:
'java h:\projects\java\compiled\bicycleMain'
Any insights would be very helpful in getting me oriented. Thanks in advance.

Interesting...so are you saying the command line might look something like this:
java -classpath h:\projects\java\compiled bicycleMain
And if I want other people to be able to execute the application without specifying the -classpath option then they would need to manually update the ClassPath environment variable on their individual PCs first?
