About JavaFX and Java Web Toolkit

DZone web site published a post named "JavaFX 2.0 Without Java VM in Web Browsers: Java Web Toolkit (JWT) compiles JavaFX down to HTML5 and JavaScript".
It's a great new!
Is this Java Web Toolkit an offcial part of JavaFX 2?

May be Oracle is also planning to do something same like Adobe did for fla to HTML5(Wallaby).
I found the performance is quiet bad during fla to html5. So I wish it wouldn't be happen to JavaFX 2.0.
Thanks.

Problem with win2000sp3 and Java web start

I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
I have win2000pro running on my PC.
I had updated win2000 to service pack 2 and everything was fine.
Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
1) Java applets seem to be running fine within i.e.
2) If i try to run an application from java web start my PC freezes and I have to restart it.
3) Staroffice 6.0, which runs on Java, seems to be fine.
I reinstalled both sp3 and jre etc, with no result.
Is this a known problem?
Thanks to all.

I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.

Serverlets, JSP and Java Web Start

Hi As I have heard J2EE is used for serverlet's and JSP programming But JSP and Serverlet programming can be created and implemented using java web start which comes with J2SE what then is the difference between J2EE and J2SE

Clarification:
J2EE has an additional E in it, while J2SE as an additional S.
Ok, now that we cleared that up, Lets see if I can answer your question.
There is no magic button such as 'java web start' that will automatically generate computer code for you. You have to write java line by line and debug each and every line of code. A typical whole project may consist up up to 1500 functions (mine has over 12000). You read whole books on the subject as I discuss below and work through thier examples. Within about 2 or 3 years of hard study, you should be a pretty good programmer.
Java is an object oriented language that you'll need to become familiar with that takes some practice to learn. Also, a java based web site consists of several technologies in addition to the java language that you'll need to be familiar with. Many programmers will read articles on the internet and pick up fragments of information on these various technologies and throw a web site together thats impossible to maintain and enhance. I think it would be better if you read whole books and experiment with the technologies. Consider it an at-come college course. Here is my suggested reading list read in roughly this order ( I suggest buying them one at a time via the internet (its cheaper) before moving onto the next book).
"Thinking In Java" - Bruce Eckel
HTML & XHTML: The Definitive Guide
JavaServer Pages - Hans Bergsten
Programming Jakarta Struts
JavaScript: The Definitive Guide
SAMs Teach Yourself SQL
JDBC and Java
Also, visit the Web Tools Platform (WTP) Project (www.eclipse.org/webtools) . Its a free Eclipse Java development tool that has the bulk of the java development IDE market (above even JBuilder).However, I suggest creating a few small java programs using the dos command line before you let this IDE do a lot of the work for you. You also might want to install some type of database (Oracle Lite, MySql, etc) on your computer so you have a database to play with (you'll need a computer with at least 2Gbytes of memory).

Java Plug-in and Java Web Start Will Not Start In JDK 1.4.2_03

I can't get the Java Plug-in or Java Web Start to start in JDK 1.4.2_03, but they did work when I first installed the JDK months ago. When I double-click either icon an hourglass displays for a second and then disappears without opening the window. I don't even get an error message.
I've tried reinstalling the JDK three times. On the last reinstall, I followed some instructions on how to completely remove the JDK. Here's the URL of the instructions I followed:

Strangely JBuilder stopped working too.
I'm running Windows 2000.
Help!
Thank you!

Hi

JRE 1.6.0_04 and java web start

Hello
Version 1.6.0_04 now contains JAX-WS 2.1
I want users install this version of java when when run my app with java web start.
So my jnlp before:
<resources>
    <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" />
</resources>I try this:
<resources>
    <j2se version="1.6.0.04+" href="http://java.sun.com/products/autodl/j2se" />
</resources>And this
<resources>
    <j2se version="1.6.0_04+" href="http://java.sun.com/products/autodl/j2se" />
</resources>But when I launch jnlp,

How can i do ?
Edited by: Laurentapo on Jan 31, 2008 6:29 AM

I honestly do believe I have read somewhere recently (some blog? where?!) that 1.6.0_04 won't be made available there as Sun would issue security release next (this? Feb?) month and did not want to bump versions in 2 consecutive months.
At least that is what I understood. Now if only I could provide link to the source where I read that... , I am sorry, am old :)

File creation and Java Web Start

Hi All,
I need to write a Java application with the following requirements and deploy the application using Java Web Start:
- Load the properties file(say, "./props/xyz.properties")
- Read the location where the file needs to be created from the
loaded properties file
- Now, create a file at the specified location.
I am able to perform the initial 2 steps after including the "props" directory(which contains the xyz.properties file) in my sigend jar file. But, unable to create a file in the specified directory.
Is it possible to create file at a predefined location(outside the jar file) within the server from where the application is downloaded?
I have included the code segment which I tried :
ClassLoader classLoader = this.getClass().getClassLoader();
// load the properties file
URL fileURL = classLoader.getResource("props/xyz.properties");
Properties props = new Properties();
props.load(fileURL.openStream());
// read the location
String location = props.getProperty("file.dir", "");
String dir = classLoader().getResource(location).getPath();
// create a new file
File newEntry = new File(dir + "raghu.txt");
newEntry.createNewFile();
Is there a way to achieve this? If so, please let me know that.
Thanks in advance,
Raghu

Allong with signing you jar, you need to request all-permissions in the jnlp file:
<security>
<all-permissions/>
</security>

Difference between reverse proxy plugin and java web proxy server

Hello
Can anyone please let me know what exactly is the difference between the reverse proxy plugin available with java system web server and the
java web proxy server.
Thanks
Manik Gupta.

The features are very closely related. The most notable and obvious difference is that The Web Proxy Server reverse proxy makes use of a content cache, while the reverse proxy of the Web Server does not cache results.

Exception while using Java Comm and Java Web Start together

Hello Java Experts!
Here's the problem that's been bothering me. The application i'm developing uses Java Comm API to listen to Serial Ports. The application works absolutely fine when it is run locally.
Now, I need to deploy this remotely using java web start. All resources(dependent jar files) are present on the server and are referenced properly in the JNLP file. All jar files are signed properly.
Still, it throws the following exception.
java.lang.NullPointerException: name can't be null
     at java.io.FilePermission.init(Unknown Source)
     at java.io.FilePermission.<init>(Unknown Source)
     at java.lang.SecurityManager.checkDelete(Unknown Source)
     at javax.comm.CommPortIdentifier.getPortIdentifiers(CommPortIdentifier.java:70)
The exact line of code where it apparently seems to error out is...
Enumeration portList = CommPortIdentifier.getPortIdentifiers();
Are there any security issues involved here? Can a application deployed through java web start access serial ports on the system?
Any pointers as to what the problem might be would be much appreciated.
Thanks in advance!

I have the IBM Communications API. I've
been told that it works with Java Web Start but I
have not tried it. IBM has changed it's download site
so.... I can't point you to it. But I have it(55k zip'ed)
and can send it to you if you post your E-Mail address
of where you would like it sent.

PS If it does work with Web Start please post the
news here. I will be watching.

RMI,Servlets and Java Web Start

I am a new developer working on a java application. My java GUI will access one server where a user will have an account. This server will store data, execute programs and access other servers for information. I have completed the GUI and I am beginning to build the client-server communication with RMI. There appear to be several tools for doing client-server communication, and while I have read much, I don't understand which is the best to explore. For applets I have read that a good method to use is servlets with RMI. But is this also true for a stand-alone application? If not, what is the best/preferred method? What if I choose to use Java Web Start (which I have not read up on, yet) will the best method of client-server communication change?
Thanks in advance, shawn

It depends on your budget too. To me the optimim way to communicate is to use SERVLET/JSP combination for client/server communication.

Http Proxy and Java Web Start 1.4.2_08

Hi All,
I'm confused as to how Java Web Start is supposed to work with an HTTP proxy. I'm testing an application in an environment which has an http proxy.
Our application starts successfully with Web Start but the application is failing to connect to URLs. I have dumped the properties right when the app starts and proxyHost, proxyPort, http.proxyHost, http.ProxyPort are all set correctly. But every attempt to connect to URLs timeout.
Note that running under 1.5, I get the value of the
javaplugin.proxy.config.list property and use it to set the properties http.proxyHost and http.proxyPort. Then I am able to connect successfully to the same URLs which failed in 1.4.2_08 ( also fails
with 1.4.2_03).
Can someone please help me understand what's wrong here?
Many thanks,
Jason

Actually, what I observed, in 1.4.2_08, is that the https.proxy* properties are being set. The http.proxy* properties are not set.
in 1.5.0_04 none of the properties are set except for
javaplugin.proxy.config.list, which I use to set http.proxyHost and http.proxyPort.

Certificate chain and Java Web Start

Hi,
I have an application as a JAR file with other JAR libraries. All these files are signed with a certificate that I have generated with my own CA (OpenSSL).
The trusted chain is this: rootCA.cer ->subCA1.cer ->jws.cer
jws.cer was generated with a Certificate Sign Request through the java KEYTOOL and then my CA has signed this request. After done this, I have put the jws.cer in the same keystore of the request but to do this I needed to put the rootCA.cer and subCA1.cer before in the keystore.
The keystore has now three certificates and the key pair of jws.cer. This certificate works good to sign the JAR files.
Is it all good?
When I call this application with Java Web Start a popup always appears and say "Certificate is valid, etc. etc.". All it's good but pop-up is shown anyway.
I have inserted the rootCA and subCA1 certificate in the client Java Web Start certificate store but the pop-up is always shown.
Why this?
Is It not enough to install the CA certificate (and then the SubCA certificate) in the JavaWS certificate (client) store to not have the pop-up visualization?
Thanks

no.
Having a validly signed certificate (even if ussing a root already in the jres trusted root ca store) only verifys who the code is comming from, it is still up to the user to determine if your are trustworthy (to grant trust based on that verified identity).
If you want to avoid seeing the certificate, you would need to import your certificate into the pre-approved certificate keystore. (that is , either into the User or System Trusted Certificates list) using the security tab on the Java Control Panel.

Bea Weblogic 6.0 and Java Web Start

We want to use Java Web Start on the Bea Weblogic 6.0 Application Server.
Is there any way to add the Java Web Start Mime Type to the Bea Weblogic 6.0 Server?
Michael

Sure, check out the documentation on adding mime types. I'm not quite sure
what mime types are supported by WebStart, but the documentation for it will
likely include that information.

Compiling JavaFX and Java into a single JAR

Perhaps I am missing something, but is there a simple way to compile both Java and JavaFX sources into a single JAR? The issue is cross references between Java and JavaFX. Using javac or javafxc separately, cross references are handled by the compiler. But as far as I can tell, there is no compiler that compiles both Java and JavaFX sources, so that nifty solution is not available. The only solution I know of (which is not simple) is to break the sources into separate collections that can be compiled separately and in the right order before building the combined JAR that I really want.

I've noticed my application has a JAD and a JAR, the JAD being much smaller. When I run the JAD a mobile emulator pops up, but it's not the same one I see when I debug. Also, pressing 'launch' does nothing.
I don't know if this is related to this original post, but how does one merge the JAD and JAR?
It seems like the emulator that comes up is related to the Mobile Toolkit. If I wanted someone to review my mobile application, what would they need to actually run this thing?

About Flash and Java in OS X Lion

Hi.
I see that Apple released two different updates to remove flashback trojan. I have read that it depends on your installation and if you have Java installed or not.
I thought that Java was included in the OS, wasn't it?
Lion doesn't have it and you have to install by yourself?
Flash should be downloaded from Adobe's site, but what about Java? It's need to install it? Should be installed? What should be safer?
So, all new computers doesn't include neither Flash neither Java, or is it something related to a clean install?
Thank you!

So, Lion, anyway you get it, won't have Java intalled, right? It doesn't matter if you get a new Mac, if you upgrade from 10.6.8, or if you clean install Lion?
Correct.
No new Mac will bring Java anymore? It's due to security?
Well, sort of. It's also due to an agreement with Oracle that they would be responsible for Java 7 and higher, but they weren't quite ready when Lion was released (it's available now).
And what about Java preferences.app? If I try to use it, it ask me to install a Java enviroment...it's just a normal thing, right?
Yes, it's normal.
Is it really more safe to have it uninstalled?
Not today, but there are known vulnerabilities in the current version that someone might figure out how to exploit in the same manner as Flashback and a couple of other malware developers did with the last version.
What can I miss if I don't install it?
You will be told if you need it. There are a few applications written either partially or completely in Java (CrashPlan is probably the most popular). Some web sites still use it. A few banks and someone said they could not get into their AT&T account without it, but I've not had any problems. I read some statistics that slightly over 5,000 of the top 1 million web sites contained Java code, so not very many.
