Difficulty in developing a Browser?

hi guys,
I am developing a web browser in java. I am able to display simple HTML page but when it comes to Applet and JavaScript it is not working. I am using JEditorPane for browser window for displaying pages. The browser is unable to display Applet, JavaScript, Flash and advanced HTML tags.
Can anyone help me regarding this? Does anyone have an idea as to how to make a browser to understand various plug-ins regarding the above types?

Please get me the solution of this problem.Sorry, I don't have a time machine to port you back in time long enough for you to create a full featured web browser in time for delivery next month, especially given the fact that I'd also need to ship a powerstation, a transformer, and everything needed to run that powerstation for a few million years.
And that's before starting on the youth drugs you'd need to be able to survive those millions of years and keep working.

hi, there is a java library called JDIC (Java Desktop Integration Component) that u can use to create such a browser.

JEditorPane really isn't up to the task on its own.
A quick search on Google for "java browser component" came up with three possibilities straight away. Perhaps you should try there first?
Hope this helps.

Problem using oai SDK to develop a browser class for iStudio

I was trying to develop a new browser class fo iStudio using the example Browser SDK Tutorial codes. The package name is defined as:
"oracle.oai.tools.iStudio.browsersdk.USIBrowser"
In iStudio's "browsers.init" I appended this line:
"FileBrowser;oracle.oai.tools.iStudio.browsersdk.USIBrowser;"
In "iStudio.bat"'s CLASSPATH I appended this entry:
"C:\oracle\OraIC\oai\tools\USIBrowser\USIBrowser.class;"
Why the hell iStudio cannot find the new class:
"menu: FileBrowser
class: oracle.oai.tools.iStudio.browsersdk.USIBrowser
java.lang.ClassNotFoundException: oracle.oai.tools.iStudio.browsersdk.USIBrowser
at java.net.URLClassLoader$1.run(URLClassLoader.java:199)
at java.awt.EventDispatchThread.run(EventDispatchThread.java:100)
Class Not Found: oracle.oai.tools.iStudio.browsersdk.USIBrowser"
Can somebody point me to the problem? Any help is appreciated.

Hi:Thanks for your response.The following code works fine in a standard VB.Net windows Application,It is just a send and receive instruction to a power meter over the GPIB bus.This code is behind a Button,and a label displays the result.I have a problem when I try to duplicate this simple code on an ASP.Net page using Server controls.When you click the button the code is supposed to execute on the server side and not the client side(browser).The code fails when it gets to the viOpenDefaultRM line,I get an error message as follows System.DllNotFoundException:Unable to Load Dll(VISA32.DLL).I have added a reference to the visa library from within the project.
'''''This is the code I am using'''''

SQL Developer Session Browser?

Does SQL Developer have any counterpart of TOAD's Session Browser (to see who else is hitting the database and with what queries)?

Thanks to both of you! This forum rocks! I am in the process of putting together a recommendation that we move from TOAD to SQL Developer; and tracking down some of the most-loved TOAD features in SQL Developer is sometimes difficult for a newbie like myself.
Again, many thanks!

To Develop a Browser using Java

Hi,
I want to know if it is possible to write a browser using java.If so where can i get more information regarding this.
Juz let me know the details.
Thanks in advance...

Dear Ramya,
You can use JEditorPane with setEditable(false) as the HTML rendering engine. For other components, you have to look elsewhere.

Newbie having difficulty centering images in browser using ActionScript 3.0

I'm a newbie using flex builder 3. I'm learning
ActionScript3.0. After running the AS code from the book, my images
are never in the center of the browser(IE7). After running the
following code (which is supposed to produce a yellow arrow, in the
center of the stage, that rotates to the mouse), I get all the
desired results except the arrow is positioned in the bottom right
corner of my browser and only part of the arrow is visible. if
anyone can suggest a solution it would be highly appreciated.
Please keep in mind that I am a COMPLETE newbie to ActionScript,
Flex Builder 3, and the Flash environments. Thanks in advance.

on mouseup or click, if the mouse is down, you can use:
stage.focus=outputText;
if the mouse isn't down, you can don't need a listener to trigger the above.

Browser Plug-in development with Java

Hiya!
My company wants me to develop a plug-in for different browsers (e.g. Internet Explorer, Mozilla, etc.) running on different platforms (e.g. Windows, Linux, etc). My first thought was that I should develop that plug-in in Java.
But how to develop a browser specific plug-in in Java? Can I use the Java plug-in provided by Sun for Internet Explorer? Do you think a browser specific plug-in developed in Java meets performance issues. Does anybody have a good idea to avoid long downloading time of JRE if not installed?
Did someone developed a browser specific plug-in in Java?
Or is it the better way to step back to C/C++ and develop an ActiveX component, ...
Please help me out ...
Best regards
Gerhard

Sun provides java plugin support for major OS's and Browsers. They also provide a helpful utility (HTMLConverter) which converts current HTML documents with <APPLET> tags to the corresponding TAGs the plugin utilizes (<OBJECT> for IE and <EMBED> for Netscape).
Do you think a browser specific plug-in developed in Java meets performance issues?
The main bottleneck occurs when the applet requires a plugin to be loaded. If loaded over the Internet on a dialup line, this can be substantial. I am testing on an intranet and it takes about 20 seconds to load the jre.
Here is a link to get started with:
http://java.sun.com/products/plugin/index-1.4.html
Pete,
PS I happen to be using the java plugin myself for the firt time and have run into a problem with installing it for Netscape on Linux. If you have successfully done this I would appreciate any advice. Below is a link to my post regarding the problem.

Safari browser is not good

I think that my question is very clear
I will repeat the question again
I and my family are facing difficulty in intensive Safari browser was very slow and I now use another browser because the browser Safari is very bad I hope you can help
Because Safari already needs to be developed
I'm sorry I do not like Safari browser
For your information I use a very high speed Internet

This thread is a follow-on to this thread.
Whether clear or not, a performance question is often not a simple question.
If a browser other than Safari meets your requirements, then by all means use it.
It would not be typical for the Safari web browser to be significantly slower than another recent web browser.
While there may be an issue with the OS X system or with the network, that would usually effect all web browsers equally; the network and DNS speeds would usually effect all systems.
There's unfortunately not much that can be done or determined here in the forums; not without more information on the configuration and the network.
Make sure the OS X system has sufficient free memory and free disk space available.
Disable any Safari extensions as a test, and use the Safari menu to select both Empty Caches... and (if that doesn't improve performance) then Reset Safari...
As a more advanced test to profile page load performance, Safari includes developer tools, and these can be enabled and used to profile what's taking time within a particular connection.
Safari > Preferences > Advanced > check Show Develop in menu bar
This might tell you what is loading more slowly.

SQL Developer High Memory Consumption 3.2.20.09.87

Hello,
I have been using SQL developer for quite some time and had initially had problems in the past with high memory consuption when I use this tool.
I have received and applied advice from this forum and while it had helped a little, the majority of the high memory consuption remained an issue.
I finally got more time to dig around and try to specifically isolate where the problem seems to be coming from and here is what I found.
*1)* I have removed the Check for Updates feature
*2)* I have turned off many of the extensions except for DBA Navigator, Real Time SQL Monitoring, SearchBar and Snippet.
*3)* When I start a fresh SQL Developer Session and initiate a Oracle Connection the application consumes roughly 148 meg fo RAM
*4)* When I open my Windows Task Manager and watch the memory allocated to SQL Developer I notice it goes up when I move my mouse over the SQL Developer tool and When I run through menus at roughly 5k a second or so and the memory is never released back to the system.
*5)* When I run a Large SQL to the grid the memory jumps by about 100 meg or so and will continue to do so every time I repeat the SQL until SQL Developer consumes roughly 748 meg of RAM.
*6)* 748 Meg of RAM seems to be the number when SQL Developer (with one Oracle connection) no longer continues to consume more and then not return the memory to the system.
Is there a way to have SQL Developer automatically clear up it's active memory usage without closing it down and restarting it?
Why does SQL Developer continue to consume more and more memory just from moving your mouse over it and/or by navigating menus?
Here is my About Detail;

Aces!!! You nailed it Gary...
Thank you.
I applied fixed noted in Re: Reduce SQLDeveloper memory footprint with JDK 1.7
For others, to summarize my changes.
product\11.2.0\client_3\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf
AddVMOption -XX:+UnlockExperimentalVMOptions
AddVMOption -XX:+UseG1GC
AddVMOption -XX:MaxGCPauseMillis=50
AddVMOption -XX:GCPauseIntervalMillis=200
AddVMOption -XX:MaxPermSize=128M
AddVMOption -Xms50M
AddVMOption -Xmx384M
AddVMOption -XX:MinHeapFreeRatio=10
AddVMOption -XX:MaxHeapFreeRatio=10
product\11.2.0\client_3\sqldeveloper\ide\bin\ide.conf
comment the following two lines as shown below
#AddVMOption -Xmx640M
#AddVMOption -Xms128M
Now SQL Developer runs at roughly 500 meg.
I guess the only thing I have left to ask others reviewing this would be if there is a way to get these memory values down without having much adverse impacts on SQL Developer based on newer JVM switches/functionalities.
The posts that drove these changes are old from a technologoical perspective :) 2010.

Popup in a Browser Air?

Hello everyone!
I develop a browser in AIR with Adobe Flash CS4! Everything is perfect, but I can not open the popup of the pages. How do I do this?
my code:
var html:HTMLLoader = new HTMLLoader();
var urlReq:URLRequest = new URLRequest("http://page");
html.width = 1024;
html.height = 600;
html.load(urlReq);
web_mc.addChild(html);
Thanks,

You can look Kidoz a AIR browser app that targets children. You'll
probably make a custom browser to target an specific audience.
Sincerely,
Michael

Why not simply use navigateToURL function ?

Best way to develop flash games for desktop + mobile, today

Hi
It has been a nice run of about 7 or 8 years now that we have developed Flash browser based games for the web exclusively. Of course with the ubiquity of mobile devices, things have changed. Clients are starting to demand, almost assume, that games will work in the browser - on the desktop and on their tablets.
Putting aside the whole discussion of using an HTML5/JS solution instead, we're sticking with Flash for the next project and need to figure out the best way to get it to run on the desktop browser and on the iPad, while maximizing code re-use.
Given the current state of technologies today, what is the best path? This game will be a 2D side-scroller type game, and development will be done mainly with bitmap graphics (as opposed to vector) and spritesheets :
Option 1: Develop the game targeting the 'standard' flash player for web, then port to an iOS AIR 3.2 app, doing appropriate optimizations.
Option 2: Use Starling/Stage3D for desktop, and then port to an iPad app. Just wondering if starling is ready for primetime making production quality games for mobile + desktop. Does Stage3D still work well enough in software mode on older machines?
Option 3: The new feature in CS6 that lets us publish to HTML5. Is this even close to mature enough to publish a full game? The benefit of this solution is that it could run in the browser on the iPad instead of being a separate app.
Thianks so much for any guidance.. I'm also wondering about pitfalls, and optimization techniques involved in any of these.

Well I don't know if I can give you 'guidance' without knowing the details of you and your project and all that, but here's my personal opinions:
Option 1: I would go for developing for iOS and Android first and then "in-brower" over the other way around. But I would actually develop for all targets at once so that I know I am not using a solution that breaks another platform/formactor that has to be redone later. iOS has allot more guidelines and things you have to consider than the the 'browser' where there is no approval proccess. So if you can get it approved on iOS then it should be able to go to Android and the browser without so much trouble, but the other way around you could really create allot of stuff that needs to be redone -- Apple is very strict on making sure that the users are not stuck with bad UI or a bad user experience(as is defined by their user interface guidelines). I have some projects that were made for in-browser flash first, and it has been hell porting them over to iOS/Android. The whole way they interact with the user has to be rethought for mobile/small screens/touch screens. If I had made them originally with mobile in mind, then it may not have been as much of an ordeal.
Option 2: I am not familiar with 'starling' or Stage3D, so I can't be helpful here.
Option 3: I was under the impression that the 'publish to HTML5' feature was just for animations, not ActionScript -- Maybe someone else can answer this for sure. Even if it could do ActionScript, there still may be no way to access some of the stuff an app could (saving levels/data/whatever to the device hard-drive, etc).
Anyhow, curious why you would want to avoid vectors? With so many screen resolutions, and the potential that they may get higher in the future (like they did with retina display on iOS), vector would make your project better suited to work on future devices without having to redo things and add higher resolution bitmaps later. If you have something that absolutely demands insane perfomance, then the bitmap/spritesheet stuff might be needed I guess... (or if it is some '8-bit retro' type of thing)

Web Browser with website filter

Hi all, I am new to here.
I'm doing my final project, which I have to develop a web browser, with some website unaccessable, like porn site.
I have totally no idea on how to do this on my browser (somemore my browser is not running properly). Got people told me that I can store those banned website's URL in a text file, then read from there and compare to the Address bar, if same then block that website.
Is there anyone here expert in develop a web browser with some specified website banned like I mentioned? If yes please please please teach me how to do this, or if have any good example for similiar porblem, please let me know. It's very important to me, THANKS !!!

Hi all, I am new to here.
I'm doing my final project, which I have to develop a
web browser, with some website unaccessable, like
porn site.You need to develop a browser? Isn't that a bit too much work for 1 person?
I have totally no idea on how to do this on my
browser (somemore my browser is not running
properly).Uh, you finished your browser already? Well then the hard part is done.
Got people told me that I can store those
banned website's URL in a text file, then read from
there and compare to the Address bar, if same then
block that website.That would be quite a bit of work. An easier approach would be to block addresses based on words appearing in them.
