Differences between Java Web Start and HTML-Applets???

Hi,
I'm trying to get information about the differences between JWS-Applets and 'normal' HTML-embedded Applets.
Is it possible to develop both simultaneously in one project???
Is there a Programming-documentation that describes the differences between JWS and HTML-Applets???
Thanx!
Rembrand

Check out the link shown below:
http://java.sun.com/products/javawebstart/1.2/docs/developersguide.html
All you need really is to create a JNLP file to launch your applet/application.

Java Web Start and DeployDirector: What's the difference?

I am the product manager for DeployDirector at Sitraka (now part of Quest Software). I'm NOT in sales; I'd simply like to provide you with some information.
From talking with DeployDirector users and evaluators, and from my own discussions with the folks at Sun, I have discovered that there is great deal of confusion about the difference between Java Web Start and DeployDirector. I'd like to clarify this by periodically posting some information about the two.
Though the products seem similar in concept, they are designed for different purposes. They both deploy, auto-update and manage the JRE for client-side Java applications, but beyond that, they are quite different.
Java Web Start is ideally designed for applications deployed over the Internet, where application-provider trust is an issue. Why? The security sandbox guarantees that application can do no harm. (There's some good information about Java Web Start and sandbox apps on ScheduleWorld at http://www.scheduleworld.com/itsYourLife.html) Web Start's architecture simply consists of a client piece that interprets a JNLP file. Because of the sandbox and its simplicity, I believe JWS is best used for independent software vendors, independent developers, etc.
Because DeployDirector is ideally designed for internal enterprise applications, it does not enforce the security sandbox. Trust is not an issue here, because internal users typically trust their internal IT group. DeployDirector's architecture consists of both a client and a server piece, which allows us to support more complex deployment and update scenarios (e.g., scheduled and optional updates) and applications management capabilities like rollback, reporting, exception monitoring, authentication/authorization out of the box. All of this is configured through the DeployDirector administration console.
In some situations, DeployDirector may be unnecessary overhead. In other situations, Java Web Start simply does not provide enough capability and building in this into Web Start can be difficult.
If you'd like more information, we have whitepapers and case studies (including one specifically about DeployDirector and JWS) available on our website at http://www.sitraka.com/software/deploydirector/
If you'd like to discuss some of these differences, or if you have questions about DeployDirector, feel free to email me directly. (Or post here, of course.)
Thanks,

Hi Gerald,
Given what I know about your emnity towards DeployDirector (which is clearly illustrated in this thread: http://forum.java.sun.com/thread.jsp?thread=348061&forum=38&message=1446155 that was evidently a response to this article: http://www.javaworld.com/javaworld/jw-11-2002/jw-1122-autoupdate.html) I'm going to take a (pardon the expression) "don't feed the trolls" approach here.
I'm simply re-iterate that JNLP, and its implementations such as Web Start and OpenJNLP, are designed for a very different set of users that DeployDirector. The differences in functionality between the two products reflect that.
The enterprise has different requirements in a deployment mechanism for its internal, critical applications than software vendors and independant developers. DeployDirector addresses the requirements of the enterprise. Frankly, most of our recent customers only chose to buy the product after initially rejecting it and (unsucessfully) attempting to use JNLP and Web Start. Sometimes people only learn the hard way: different users have different requirements which are suited to different tools or technologies.

What's the difference between a web site and a web application?

I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
Or maybe I'm totally wrong here - what differenciates between a web application and a website?

This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
runs remotely, and it depends fundamentally on a processing and a data storage backend.

There is no real "difference". Web site is a more anachronistic term that exists from the early days of
the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
more like an application as a web app.
The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.

Java Web Start vs Signed Applet

What is the difference between a web start application and a signed applet.
I tested both but i dont see any advantage to web start.
Someone can tell me ?

christophe,
There is another thread on this topic in this forum...it is titled "Really basic question: why?"

64bit, java web start, media framework, applets avi mov e.s.o.

Using 64bit, (SuseLinux), nothing works i.e. webbrowsers (firefox),
java web start, media framework, applets, avi, mov, e.s.o.
-How to do to work around this? (I have latest jre+sdk 6)
(note: firefox doing stupid thing when try to download plugin)
Is it possible to write some kind of HTML-code to download an
JAR-file from my (domain) webserver? And then: How to start it? (subject above)

Works just fine for me, too even though the "instructions" do not mention any Mac OS or browser.
Are you really at 10.4.8? Use Software Update to move up to 10.4.11.

Mac OS 10.4.8 , Java Web Start and JRE version of 1.4.2 and 1.5.0 problem

Hello,
I've been searching internet and reading the problems related to Java Web Start and JNLP.
But no solution I read can solve what I faced.
I'm running Mac OS x 10.4.8 and Macintosh updates the Java in my machine so that it has Java version 1.4.2 and Java 1.5.0
The application I'm running needs to be running in JRE 1.4.2.
So I changed the Java Preferences so that the default Java setting is JRE 1.4.2. However, the JNLP application still running in Java 1.5.0
So I changed the MIME and make sure the JNLP is opened with Java Web start instead. The Java Web start is for version 1.4.2. I also change its preference so that the console is opened.
I tried to run the JNLP application once again. Java web start 1.4.2_09 starts and console open, but the Java Runtime is still showing Java 1.5.0
I adjust the JNLP file so that the version is only showing 1.4.2_09 (ignoring all other variables of version 1.4.1, 1.4.2, etc found in the original JNLP file). That didn't work either.
I search on methods on how to uninstall Java 1.5.0 in Mac - apple page told me that I can't do that unless I reinstall the whole OS.
I am henceforth declare that I am stuck now !!!! Heellllpp....

Are you up to date with the updates?
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:
http://support.apple.com/kb/HT5666
and Update No. 14 on March 4: http://support.apple.com/kb/DL1573
http://support.apple.com/kb/HT5677
The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

Java Web Start and JNLP Problem

Hi !
I�m a student and i need your help for a work that i have to do.
I have an aplication that parse an XML file.
The XML file is in ther server, and when i run the aplication with Java Web
Start and jnlp file i want that the application parse a XML file.
is this possible??? how can i do ???
if you dont understand please warn me, that i try to explain better..
thanks, in advance.
Rui Silva , Portugal

I'm not sure that you need webstart.
Just an applet will allow you to read a file from the server:
Just open a URL pointing to the .xml file.
Read the file into a buffer and then parse it.
Now actually getting the applet to do something with the contents of the .xml file
is more complicated. Presumably you need to write something which understands the
contents of the .xml and does something in response to the contents.
A signed java program can be run from with in webstart which can spawn processes on
the local machine. os.systemExec("command a b c"); But of course that has cross platform
problems.
Good luck

Java Web Start and Java Preferences

I am having trouble with Java Web Start and Java Preferences. I have tried reinstalling the update with the link http://www.apple.com/downloads/macosx/apple/application_updates/javaformacosx105 update6.html but to no avail. What else can be done ? Moreover the file /System/Library/Frameworks/JavaVM.framework/Versions/A/ seems to be in place, but Java Web Start wont open and Java Preferences can't access cache files. Any ideas about how to resolve this? I have been having issues with Java for a long time and have already done a clean Leopard reinstall and all the Combo updates. Java Web Start and Java Preferences worked correctly for a while after that but seem to have gone haywire again.

Java Web Start and pack200

Hi!
What do I have to do to deploy my jar-archives that are packed with pack200? Do I have to change the jnlp files? Do I have to change any server settings?
At the moment I successfully deploy our software using Java Web Start and simple jar files. If I pack with pack200 the archives shrink to 1/4 of the original size. That is nice, but when I put the xxx.jar.pack.gz files on our web server they are ignored by Java Web Start. Explicitly use the xxx.jar.pack.gz files in the jar arguments of the jnlp file doesn't work either (because JWS expects .jar archives there it tells me that the archives are corrupted).
I figure that I have to change either the jnlp file, the server settings or the JWS clients settings.
In another posting I have read that JWS in its normal configuration does not support pack200 at all. Is that correct? Or is there a straight-forward documentation how to use JWS with pack200?
Thanks in advance,
Chris,
Hamburg

Either the JWS plugin should try to request the "xxx.jar.pack.gz" file when it finds a "xxx.jar" reference in the jnlp file.No. You always request jar files, but the Accepted-Ecnoding can differ. If omitted or empty the server should send back the contents of the jar, if it's "gzip" than the stuff of the jar.gz (Content-Encoding: gzip) and if it "pack200-gzip" the stuff of the jar.pack.gz (Content-Encoding: pack200-gzip).
The diagrams shown here make it pretty obvious:
http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/pack200.html
So... you need some server sided logic for handling that. If you can run servlets - great... just use Sun's example. If you can't, you'll need something else like apache's mod_rewrite and a php script.
mod_rewrite is used for redirecting requests server sided. For example:
http://onyx.bubblegumcrises.jp/jnlp/downloads/fake.jar [no real url]
becomes:
http://onyx.bubblegumcrises.jp/jnlp/jarbounce.php?file=fake.jar (internally) [no real url]
by rewriting like this(jnlp/.htaccess):
RewriteEngine On
RewriteBase /jnlp
RewriteRule downloads/(.*) jarbounce.php?file=$1 [NE]
The php file then checks the filename (for security reasons) and the accepted encoding and sends the contents of a file (picked by AE and availability) back together with the correct headers (Content-Encoding reflecting the picked encoding and Content-Type set to "application/x-java-archive").
I've written such a script yesterday and I'm going to make it public. However, I want to do some more checks before releasing it (I ended up here by googling around... I wanted to avoid reinventing the wheel again ;)).
I'll post it over at JGO pretty soon now... in this thread:
http://www.javagaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=OnLin;action=display;num=1097590751;start=0

Difference between SAP web AS and ITS

Hi everyone,
Can anyone tell me the difference between SAP web AS
and ITS.

Hi Aditya, please let me know if the following helps.
What exactly is the SAP Web Application Server?
The SAP Web Application Server is the reliable, open standard-based application server from SAP. It supports both J2EE and ABAP, and serves as the underlying infrastructure for all new and upcoming SAP solutions, like SAP R/3 Enterprise, SAP Portal, SAP Exchange Infrastructure, and all other SAP components. The SAP Web Application Server is not a new product, it is the natural evolution of proven SAP application server technology formerly known as SAP Basis. It provides the platform to develop, execute, and operate Web applications and Web services as well as traditional SAP GUI based applications
Does the SAP Web Application Server replace the SAP Internet Transaction Server (SAP ITS)?
No, the SAP Internet Transaction Server (SAP ITS) will continue to be supported in the future and is integrated into Web Application Server from version 6.40 on. This is because the SAP ITS will in future display Dynpro-based SAP applications to the Web, either using the HTML-GUI or with HTML-template based IACs. This integration reduces the additional hardware for an external ITS. All SAP ITS based applications and the administration will work as before.
Flow Logic technology will also not be supported by the SAP Web Application Server. ITS Flow Logic is an approach to Web application development that is now completely covered by the new "Business Server Pages" technology and others. New applications based on ITS Flow Logic are no longer developed by SAP. Existing applications based on ITS Flow Logic will continue to be supported. SAP recommends customers use the Business Server Pages for new projects or projects in an early stage of development instead of ITS Flow Logic.
If the above didnt help, please let me know, I can try to resaerch more links and let me know..
Thanks

Difference between Java 1.2 and 1.4

Can Anyone tell me the Difference between Java 1.2 and 1.4

Hi,
Well to start with, a hell lot of classes have been added, and others have been altered. The only change in the language is that the assert statement was added.
An application written in 1.2 will most likely run under 1.4.

Java Web Start and C++ executable

Can anyone please help me to deploy an application including three C++ executables using Java Web Start?
I packaged each .exe file into .jar and created a java program called "ExecTest" that attempt to launch the .exe by calling Runtime.exec (someapp.exe).
My JNLP file looks like:
<resources>
<jar href="app/someapp.jar"/>
<jar href="ExecTest.jar" />
</resources>
<application-desc main-class="ExecTest">
The problem I am having is that Runtime.exec wants the full absolute pathname for the executables. But the cached jar files all have some arbitrary letters prefixed, so I cannot specify them beforehand.
Any ideas?
Thanks in advance.
Suh from Toronto. (Go! Leafs Go!)

I've deployed serialio.com's replacement for javax.comm via Java Web Start, and I managed to package the .dll in a .jar without any difficulties.
Perhaps the System.loadLibrary() function knows about the renaming that Java Web Start does...
If so, then the following might do the trick:
- Use System.loadLibrary() to load your .exe file. Windows uses the same fileformat for DLLs and EXE files, and hence System.loadLibrary() should be a safe no-op. Presumably you are
- Use System.mapLibraryName() to find the full path to your .exe.

Difference between a WEB service and a Enterprise Service?

Can Anybody explain me the difference between a WEB service and a Enterprise Service?

Hi Anilkumar K Naidu ,
Web service
A Web service is a self-contained, modularized functionality, which can be published, discovered, and accessed across a network using open standards and which is supported by SAP NetWeaver. Web services cover services provision for integration within an enterprise as well as cross enterprises on top of any communication technology stack, whether asynchronous or synchronous, in any format.
Web Services in the NetWeaver framework play an important role in facilitating the integration of disparate applications from various departments or trading partners and thus increasing business productivity. This benefit allows small and medium businesses also to integrate their business applications with larger trading partners. The benefit derived from this seamless integration introduces security concerns when all the business logic is now being exposed through a standard interface that is a catalyst for security vulnerabilities. SAP Security Managers must use automated diagnostics tools to ensure that the security vulnerabilities are caught in pre-production and in post-production phase.

Enterprise Service
Enterprise Service-Oriented Architecture (Enterprise SOA)
Enterprise SOA is a blueprint for an adaptable, flexible, and open IT architecture for developing services-based, enterprise-scale business solutions. With SAP NetWeaver as a technical foundation, enterprise SOA moves IT architectures to higher levels of adaptability and moves companies closer to the vision of real-time enterprises by elevating Web services to an enterprise level.
An enterprise service is typically a series of Web services combined with business logic that can be accessed and used repeatedly to support a particular business process. Aggregating Web services into business-level enterprise services provides a more meaningful foundation for the task of automating enterprise-scale business scenarios.

Java Web Start and Policy File

Hi,
I've a problem for Java Web Start (JWS) in working with Policy File.
I like to apply a policy file for a JWS application to fine tune the secuirty setting instead of granting permission in JWS.
For an applet environment, I can apply policy file like this:
appletviewer -J"-Djava.security.policy=all.policy" writeFile.html
However, in JWS environment, I try to apply in JNLP file as below but fail:

There are two problems with what you are trying to do.
First, setting a property PROP=VALUE in the jnlp file does not mean that java will be launched -DPROP=VALUE, instead, javawebstart will call System.setProperty(PROP,VALUE) before your apps main() is called. The difference is, the property will not be set at the time the VM is initialized.
Second, the javaws security policy will not allow you to set arbitrary properties in an unsigned application. Only properties begining with "jnlp." or "javaws." (and possibly a few other specific props known to the native javaws code) can be set in an application unless <all-permissions> is specified and the app is signed.

Java Web Start and hsqldb

How can I set hsqldb standalone database to use within a Java Web Start compliant Application?

Yes, this shouldn't create any problems, you can run hsqldb as standalone:
From the documentation (http://hsqldb.sourceforge.net/web/hsqlModes.html)
The In-Process mode is also referred to as Standalone. In this context, Standalone means use within a standalone application as opposed to a client application accessing a database server. The database is running in the same Java Virtual Machine as the application. It acts as an embedded code library used by the application program. The application and the database engine communicate through normal JDBC calls but these calls are handled internally without a network connection.
In this mode, only one application can access a database at a time. To access the same database at the same time from multiple JVM or computers the Client/Server mode must be used.
The JDBC URL for the In-process (Standalone) mode is:
jdbc:hsqldb:test
where test is the database file name. Another example (Windows) is:
jdbc:hsqldb:c:\db\test
This means that you can refer to a file eg. in the JAR which contains the database.
If you want to store between client sessions, you need to retrieve the file from the JAR and store it on the user's hard drive (f.eks. in the user's home directory) and then check if it exists when your application is started. If it does, open the hsqld file on the user's hard drive, it if doesn't retrieve it from the JAR which you are running app from.
Hope this was understandable :)
