Endorsed Standards Overriding Mechanism
Hi all,
is the 'Endorsed Standards Overriding Mechanism' supported in JNLP files? I couldn't get any information from the JNLP Specs or in this forum.
There must be a way to do this; since I expect others having problems with the standard xml parser / xslt processor bundled with the JRE, too.
I just want to use a specific version of eg. Xalan and Xerces in my webstart application. And normally you use the 'Endorsed Standards Overriding Mechanism' to accomplish this. However, with Webstart I couldn't get it to work.
Daniel
I don't think you can do this through the JNLP in a reasonable way. We had the same problem and we ended up using creating the Xerces parser in a somewhat hard-coded manner. See http://forum.java.sun.com/thread.jsp?forum=38&thread=231995

Endorsed Standards Override Mechanism
Has anybody had the need to do this? (http://java.sun.com/j2se/1.4.2/docs/guide/standards/)
I jave a third party jar file that complains about needing a xml parser that supports DOM3 calls. It included a Sun JAXP 1.3 parser. But it suggests that if you use Java 1.4 that you need to do this "Endorsed Standards Override Mechanism" thing. Do you know how to do this for JDEV 10.1.2? Does run under 1.3.1 OK.The message suggests to set an option xendorsed="true" on the <wsimport> task. This task ist normally found in your ant build file build.xml of your NetBean project.

Attn: Sun. Can we distribute the JRE with a program we write?
I'm trying to find out whether it's legal to distribute the JRE with a program I write. If you look at the license agreement when you download the JRE, first it has the regular license agreement, which says that you can't. But then it has the "supplemental" license agreement (and it says that this "modifies" the regular license agreement). In section 2 of the supplemental license agreement, it quite clearly states that you can as long as you don't modify it and you include some little messages in your documentation.
So I'm hoping to get an answer from someone who actually works for Sun. It seems pretty clear to me that we ARE allowed to distribute the JRE with a program, but people keep sending me emails when I tell them about it - saying things like "You can't program in Java because you can't distribute it."
What I want to do is have an installation program that installs my game and then installs Java (with Sun's JRE installer - this is included ONLY so that it can run my game, as stated in the supplemental license agreement). I should also mention that I do actually intend to SELL this program, so if that's a problem, please say so. Anyways, could someone from Sun tell me whether this is allowed or not? I don't want to break the law.
- Steve FletcherThe JRE includes a readme file that explicitly states that distribution is permissible, given certain conditions. In particular, look at the 1st paragraph below:

README
Java(TM) 2 Runtime Environment, Standard Edition
Version 1.4.1
The Java(TM) 2 Runtime Environment is intended for software developers
and vendors to redistribute with their applications.
The Java 2 Runtime Environment contains the Java virtual machine,
runtime class libraries, and Java application launcher that are
necessary to run programs written in the Java programming language.
It is not a development environment and does not contain development
tools such as compilers or debuggers. For development tools, see the
Java 2 SDK, Standard Edition.
=======================================================================
Deploying Applications with the Java 2 Runtime Environment
=======================================================================
When you deploy an application written in the Java programming
language, your software bundle will probably consist of the following
parts:
Your own class, resource, and data files.
A runtime environment.
An installation procedure or program.
You already have the first part, of course. The remainder of this
document covers the other two parts. See also the Notes for Developers
page on the Java Software website:
http://java.sun.com/j2se/1.4.1/runtime.html
Runtime Environment
To run your application, a user needs the Java 2 Runtime Environment,
which is freely available from Sun for application developers to
redistribute.
The final step in the deployment process occurs when the software is
installed on individual user system. Installation consists of copying
software onto the user's system, then configuring the user's system
to support that software. You should ensure that your installation
procedure does not overwrite existing JRE installations, as they may
be required by other applications.
=======================================================================
Redistribution of the Java 2 Runtime Environment
=======================================================================
The term "vendors" used here refers to licensees, developers, and
independent software vendors (ISVs) who license and distribute the
Java 2 Runtime Environment with their programs.
Vendors must follow the terms of the Java 2 Runtime Environment Binary
Code License agreement.
Required vs. Optional Files
The files that make up the Java 2 Runtime Environment are divided into
two categories: required and optional. Optional files may be excluded
from redistributions of the Java 2 Runtime Environment at the
licensee's discretion.
The following section contains a list of the files and directories that
may optionally be omitted from redistributions with the Java 2 Runtime
Environment. All files not in these lists of optional files must be
included in redistributions of the runtime environment.
Optional Files and Directories
The following files may be optionally excluded from redistributions:
lib/charsets.jar
Character conversion classes
jre/lib/ext/
sunjce_provider.jar - the SunJCE provider for Java
Cryptography APIs
localedata.jar - contains many of the resources
needed for non US English locales
ldapsec.jar - contains security features supported
by the LDAP service provider
dnsns.jar - for the InetAddress wrapper of JNDI DNS provider
bin/rmid
Java RMI Activation System Daemon
bin/rmiregistry
Java Remote Object Registry
bin/tnameserv
Java IDL Name Server
bin/keytool
Key and Certificate Management Tool
bin/kinit and jre/bin/kinit
Used to obtain and cache Kerberos ticket-granting tickets
bin/klist and jre/bin/klist
Kerberos display entries in credentials cache and keytab
bin/ktab and jre/bin/ktab
Kerberos key table manager
bin/policytool
Policy File Creation and Management Tool
bin/orbd
Object Request Broker Daemon
bin/servertool
Java IDL Server Tool
In addition, the Java Web Start product may be excluded from
redistributions. Depending on the platform, the Java Web Start
product is contained in a file named as follows. The actual
product version number would replace the <version number> notation.
javaws-<version number>-solaris-sparc-i.zip
javaws-<version number>-solaris-i586-i.zip
javaws-<version number>-linux-i586-i.zip
javaws-<version number>-windows-i586-i.exe
Redistribution of Java 2 SDK Files
The limited set of files from the SDK listed below may be included in
vendor redistributions of the Java 2 Runtime Environment. All paths
are relative to the top-level directory of the SDK.
- jre/lib/cmm/PYCC.pf
Color profile. This file is required only if one wishes to
convert between the PYCC color space and another color space.
- All .ttf font files in the jre/lib/fonts directory. Note that the
LucidaSansRegular.ttf font is already contained in the Java 2
Runtime Environment, so there is no need to bring that file over
from the SDK.
- jre/lib/audio/soundbank.gm
This MIDI soundbank is present in the Java 2 SDK, but it has
been removed from the Java 2 Runtime Environment in order to
reduce the size of the Runtime Environment's download bundle.
However, a soundbank file is necessary for MIDI playback, and
therefore the SDK's soundbank.gm file may be included in
redistributions of the Runtime Environment at the vendor's
discretion. Several versions of enhanced MIDI soundbanks are
available from the Java Sound web site:
http://java.sun.com/products/java-media/sound/
These alternative soundbanks may be included in redistributions
of the Java 2 Runtime Environment.
- The javac bytecode compiler, consisting of the following files:
bin/javac [Solaris(TM) Operating Environment
and Linux]
bin/sparcv9/javac [Solaris Operating Environment
(SPARC(TM) Platform Edition)]
bin/javac.exe [Microsoft Windows]
lib/tools.jar [All platforms]
- jre\bin\server\
On Microsoft Windows platforms, the Java 2 SDK includes both
the Java HotSpot Server VM and Java HotSpot Client VM. However,
the Java 2 Runtime Environment for Microsoft Windows platforms
includes only the Java HotSpot Client VM. Those wishing to use
the Java HotSpot Server VM with the Java 2 Runtime Environment
may copy the SDK's jre\bin\server folder to a bin\server
directory in the Java Runtime Environment. Software vendors may
redistribute the Java HotSpot Server VM with their
redistributions of the Java Runtime Environment.
Unlimited Strength Java Cryptography Extension
Due to import control restrictions for some countries, the Java
Cryptography Extension (JCE) policy files shipped with the Java 2 SDK,
Standard Edition and the Java 2 Runtime Environment allow strong but
limited cryptography to be used. These files are located at:
<java-home>/lib/security/local_policy.jar
<java-home>lib/security/US_export_policy.jar
where <java-home> is the jre directory of the Java 2 SDK or the
top-level directory of the Java 2 Runtime Environment.
An unlimited strength version of these files indicating no restrictions
on cryptographic strengths is available on the Java 2 SDK web site for
those living in eligible countries. Those living in eligible countries
may download the unlimited strength version and replace the strong
cryptography jar files with the unlimited strength files.
Endorsed Standards Override Mechanism
An endorsed standard is a Java API defined through a standards
process other than the Java Community Process(SM) (JCP(SM)). Because
endorsed standards are defined outside the JCP, it is anticipated that
such standards will be revised between releases of the Java 2
Platform. In order to take advantage of new revisions to endorsed
standards, developers and software vendors may use the Endorsed
Standards Override Mechanism to provide newer versions of an endorsed
standard than those included in the Java 2 Platform as released by Sun
Microsystems.
For more information on the Endorsed Standards Override Mechanism,
including the list of platform packages that it may be used to
override, see
http://java.sun.com/j2se/1.4.1/docs/guide/standards/
Classes in the packages listed on that web page may be replaced only
by classes implementing a more recent version of the API as defined
by the appropriate standards body.
In addition to the packages listed in the document at the above
URL, which are part of the Java 2 Platform, Standard Edition
(J2SE(TM)) specification, redistributors of Sun's J2SE
Reference Implementation are allowed to override classes whose
sole purpose is to implement the functionality provided by
public APIs defined in these Endorsed Standards packages.
Redistributors may also override classes in the org.w3c.dom.*
packages, or other classes whose sole purpose is to implement
these APIs.

Create service attempt not working
I am using NetBean 6.7 to build client service using Tomcat 6.1.20.
Everytime I attempt to build it gives me back the message:
You are running on JDK6 which comes with JAX-WS 2.0 API, but this tool requires JAX-WS 2.1 API.
Use the endorsed standards override mechanism
(http://java.sun.com/javase/6/docs/technotes/guides/standards/), or set xendorsed="true" on <wsimport>.
Can I correct this issue without downloading anymore software and how do I correct it?
I tried finding xendorsed and it didnt show in any of my Tomcat files.
Please advise.The message suggests to set an option xendorsed="true" on the <wsimport> task. This task ist normally found in your ant build file build.xml of your NetBean project.

I think I have tried everything to compile the web service in the web service tutorial. I was using Netbeans 5.5 and was receiving an error. I switched to version 6.0 Dev to see if it would work and I'm now receiving the following error...
C:\Documents and Settings\Gary\WSTest\nbproject\build-impl.xml:315: You are running on JDK6 which comes with JAX-WS 2.0 API, but this tool requires JAX-WS 2.1 API. Use the endorsed standards override mechanism (http://java.sun.com/javase/6/docs/technotes/guides/standards/), or set xendorsed="true" on <wsgen>.
I downloaded jax-ws 2.1 and jaxb 2.1 and added those libraries to the project.
I created an endorsed folder under the c:\program files\java\jre1.6.0 folder and copied the files from jaxws-ri/lib to it.
I don't know how to set xendorsed on wsgen.
I can't seem to get any thing to work.
Thanks for any help!!!!

Our application is downloaded to the client via a browser and consists of two jars, one for the application itself, the other containing XML parsers, a cut down version of JAXP
On JRE 1.3 all runs well since it uses the parsers contained in the downloaded jar, however when running under 1.4 the plug-in uses its own bundled parsers which our application does not like.
How can I force the plug-in to use the parsers contained in the jar downloaded to the client instead of its own ?
By the way, if I run the app using appletviewer on 1.4 everything works fine, so whats happening there ?
Thanks.There's a feature called "Endorsed Standards Override Mechanism" which you can read about here:
http://java.sun.com/j2se/1.4.2/docs/guide/standards/index.html
You may be able to use that to force the use of your parsers, although from the list of overridable packages it looks like you can't. The way I use Saxon instead of JAXP to do XSLT transformations is to put this line of code in my initialization:System.setProperty("javax.xml.transform.TransformerFactory","com.icl.saxon.TransformerFactoryImpl");and there are similar properties for SAXParserFactory and DocumentBuilderFactory, I suppose, but I haven't used them. However if your cut-down JAXP classes have the same names as those in the full-blown JAXP, that isn't going to work for you either.
I just had a look at the documentation for DocumentBuilderFactory's constructor, and it does mention the name of the system property that you can use; it also mentions a couple of other techniques you can use to control what class is loaded by the factory. -
Overriding or nulling accessibility class metatag (JAWS)
I am trying to disable the AccessibilityImplementation in parent components and allow children components, for example (disable a datagrid's accessibility implementation and allow the labels and text input (from that same datagrid control item renderers), to expose their accessiblity name to jaws).
I was able to do it, and it works perfectly using the monkey patch approach, I copied the source code from mx.controls.Datagrid.as and removed the line 534 [AccessibilityClass(implementation="mx.accessibility.DataGridAccImpl")] and it works as we need. We can also do our own AccessibilityImplementation as we need.
The question is.. can we from an extended class, set to null the accessibilityclass meta tag value
the following code throws a compile error, please check
package mx.controls
[AccessibilityClass(implementation=null)]
public class ExDataGrid extends DataGrid
public function ExDataGrid()

I think reply 7 of 7 puts some good points.
it says,
The question then becomes of course why cannot variables be overridden?
Well, technically I suppose they could be but the purpose of overriding is to change the behaviour of subclasses
and variables don't represent behavior, they represent stateand it seems variables have nothing got to do with overriding, it is just the latest attribute up the stack that is used.Well, I was uj_ once so I wrote that. -:)
It's just another way to express my reply #2 in this thread.
There's a division of labour between methods and variables. Non-private methods represent the behavior of a type, whereas variables represent implementation and object state none of which should be exposed in a type. And because the purpose of the overriding mechanism is to modify the behaviour of subtypes, overriding really doesn't make sense for variables.
There's a greyzone here though and that concerns so called "properties". Are they behavior or are they state? Well, it's bad encapsulation to expose naked variables in a type so if a variable represents a "property" it should be embedded in a getter/setter pair. This means that "properties" should be represented by methods in the type. The question now is whether a subtype should be able to override and modify a "property" defined by the superttype? Well as a programmer you can prevent that by declaring the "property's" getter/setter methods final.
The conclusion I'm making is that naked variables never belong in a type so making them overridable makes no sense. If a variable represents a "property" it should be exposed via a getter/setter pair. The programmer then can decide whether this "property" should be overridable by declaring the getter/setter pair final or not. -
Runtime Error that Seems to be Related to Dialog Boxes
Although I am currently taking a college course in Java and my code is based on a couple of questions from my Java textbook, I would like to make it perfectly clear that this is NOT homework. This is self-assigned for studying purposes and my professor will probably never see this, let alone grade it. Regardless, I suspect this to be a configuration-related issue as I had no such problems running this program in a Vista machine on campus. Assuming I am right, there shouldn't be any issue with any of this community's policies as I won't need to receive any "answer" code to solve this issue.
In NetBeans, my program compiles and works fine, but produces a couple of runtime errors. Any idea what could be going on here?
Here's my code:
import java.util.Scanner; // Needed for console input.
import javax.swing.JOptionPane; // Needed for dialog boxes.
This program performs the actions requested in questions 2.35 and 2.36 in the textbook.
* @author Dan
public class Pages98To99 {
public static void main(String[]args){
// Asks the user for what answer he/she wants to see.
System.out.println("Do you want to see the answer to 2.35 or 2.36?");
Scanner keyboard = new Scanner(System.in); // Creates a scanner object.
double answer = keyboard.nextDouble();
if (answer == 2.35){
//2.35
JOptionPane.showMessageDialog(null, "Greetings Earthling.");
JOptionPane.showInputDialog("Enter a number.");}
else if (answer == 2.36){
//2.36
String str = JOptionPane.showInputDialog("Please enter your age.");
// Gets age.
int age = Integer.parseInt(str);} /* Converts age from a string to an

else
JOptionPane.showMessageDialog(null, "Go to another program.");
System.exit(0); // Ends the program

I would like to use Java version 6.Hi John,
I sort of remember Java 6 being IntelMac only...
Once you’ve gotten logged in, go to Downloads, select “Java” on the right hand side of the page, and download the Java SE 6 beta. Note: this is only available for Intel Macs running Tiger or Leopard — if you’ve got a G4 or G5, you’re out of luck right now
http://www.metaphoriclabs.com/articles/installing-java-6-on-mac-os-x/
But here they are...

Can I do Java 6 development in OS X?...

How to compile and run package programs in Java
Hi,
I want to know how to compile and run the package programs in Java using -d. instead of creating the package folder manually.
eg:
package Test;
class test1
public void disp()
//Any code;
I want to compile this without creating the folder ' Test ' manually. that is if we use -d with javac the Test folder will be created automatically. I need the format of -d
could anyone please help me.
Thanks in Advance ,
AmbikaMy program Test.java in F:\Tomcat5\webapps\Ambika\WEB-INF\Classes. I compiled in the format below. I got like this. What should I do for this? But yesterday I compiled like this only, It compiled and the folder com\cert\Test.class is created. Today again I compiled the pgm after deleting the already created folder 'com\cert', I got the error like this.
I've given my pgm and the thing I've got when I compiled it.
Test.java
package com.cert;
public class Test
public void display()
System.out.println("Hai");
F:\Tomcat5\webapps\Ambika\WEB-INF\Classes>javac -d F:\Tomcat5\webapps\Ambika\WEB-INF\Classes\Test.java

Verifying OpenOffice document signature
Hi all,
When you sign an ODT document throught OpenOffice interface, an XML Signature file is generated inside ODT file structure: documentsignatures.xml.
I'm trying to verify this XML Signature using JDK 6 JSR 105 implementation, but i have some problems ...
I try a simple verification uncompressing ODT file (JAR file) and accessing documentsignatures.xml directly:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document d = db.parse("documentsignatures.xml");
NodeList nl = d.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");
X509Certificate cert = X509Certificate.getInstance(new FileInputStream("rootca.der"));
DOMValidateContext valContext = new DOMValidateContext(cert.getPublicKey(), nl.item(0));
XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");
XMLSignature signature = fac.unmarshalXMLSignature(valContext);
if (signature.validate(valContext)) {
System.out.println("OK");
else {
System.out.println("BAD SIGNATURE");
}But i get an exception:
Exception in thread "main" javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.URIReferenceException: java.lang.NullPointerException
at org.jcp.xml.dsig.internal.dom.DOMReference.dereference(DOMReference.java:352)
at org.jcp.xml.dsig.internal.dom.DOMReference.validate(DOMReference.java:311)
at org.jcp.xml.dsig.internal.dom.DOMXMLSignature.validate(DOMXMLSignature.java:230)
at VerifyODTSignature.main(VerifyODTSignature.java:63)It seems like a problem with reference resolution ... So i modify the initial code to handle an "URIDereferencer":
DOMValidateContext valContext = new DOMValidateContext(cert.getPublicKey(), nl.item(0));
valContext.setURIDereferencer(new URIDereferencer() {
public Data dereference(URIReference uriReference, XMLCryptoContext context) throws URIReferenceException
OctetStreamData osd = null;
try
osd = new OctetStreamData(new FileInputStream("/referenced_xml_files/" + uriReference.getURI()));
catch (Exception e)
e.printStackTrace();
return osd;
});But i get an:
Exception in thread "main" javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.dsig.TransformException: java.lang.ArrayIndexOutOfBoundsException: 23
at org.jcp.xml.dsig.internal.dom.DOMReference.transform(DOMReference.java:390)
at org.jcp.xml.dsig.internal.dom.DOMReference.validate(DOMReference.java:312)
at org.jcp.xml.dsig.internal.dom.DOMXMLSignature.validate(DOMXMLSignature.java:230)
at VerifyODTSignature.main(VerifyODTSignature.java:62)I supose that i'm not usign URIDereferencer properly, but i could'n find documentation or samples regarding this issues :(
Please, somebody can help me?
Thanks in advance!!!!
Edited by: borillo on Mar 4, 2008 8:23 AMHi all,
Finally Sean Mullan have found the problem. Here is his answer:
I finally found some time to debug into this problem. It is a bug in the canonicalization code and I will open a bug to have it fixed in JDK 6. It is only triggered if an element has over 23 attributes and the
office element in content.xml has 24 attributes!
The only workaround I can think of is to use a Apache XMLSec jar and override the implementation in the JDK. You can do this with the endorsed override mechanism of the JDK. What you need to do is download the following jars:
1) Java XMLSec (1.4 or later): http://xml.apache.org/security/dist/java-library/
2) Commons Logging:
http://commons.apache.org/downloads/download_logging.cgi
You need the commons logging library because the Apache implementation uses that instead of the JDK logging mechanism.
Put these two jars in a lib directory, and then specify that lib directory as the endorsed directory when running your application, for example:
java -Djava.endorsed.dirs=lib ...
This should work.
HTH,
Sean
