IIS (proxy) plug-in and gif images

I was wondering if anyone has run into the problem of not having the linked images load/show up that within a jsp going thru the iis proxy plug-in setup?

Hello,
 If the GIF images are located on the WebLogic Server, then you need to setup
 IIS to proxy .gif to WebLogic as well.
 It is recommended to place the GIf images on IIS as static content should be
 served by IIS for performance reasons.

How to decoding and encoding PNG and GIF images?

I could decode and encode JPEG images using following create functions which are in com.sun.image.codec.jpeg package.
JPEGImageDecoder decoder = JPEGCodec .createJPEGDecoder(inputStream);
JPEGImageEncoder encoder = JPEGCodec .createJPEGEncoder(outputStream);
But I dont know required package and functions to decode and encode PNG and GIF images. Please help me.

Is the API that hard to follow?
ImageIO.read( file/stream/url)
ImageIO.write( image, format (e.g. PNG, GIF(1), JPEG), file/stream what have you)
1) Not sure if Java supports GIF saving, it might if you install JAI, or Java 6.

Reverse Proxy plug in and Load Balancer Plug in

Hi,
Can anyone please provide me with an example obj.conf file showing how to combine the reverse proxy plug-in and Load Balancer plug-in.
I would like to use the reverse proxy plug in to detect when static content is requested and provide this from the web server. Requests for dynamic content would then be forwarded to an Application server via the Load balancer plug-in. I have found plenty of documentation on how to configure these plug-in separately but nothing on how to combine the two.

smiking
reverse proxy plugin - its job is to forward the requests to another server for a specific task. you can use the webserver 7 . it does forward and limited load balancing (using round robin ) based on the number of servers you provide in the configuration. i would say this is a poor man's setup.
load balancer plugin - some app servers like sun java system app server or web logic provide this plugin so that you can effectively use the back end app server
with both these setup, you can <if> constructs to determine which requests need to be forwarded to the back end server.
I wonder, why do you need both - if both of them is designed to do the same thing.

IIS proxy 5.1 and Weblogic 6.1 does not support sticky session

Dear Sir,
Our system is migrating from Weblogic 5.1 to Weblogic 6.1. After testing on
development environment, it is found that IIS proxy for 5.1 plug-in and Weblogic
6.1 server is perfect match for our case. Since our appliction system hit some
bugs of IIS proxy for 6.1. In development environment, one IIS match with one
Weblogic.
During production launch, another problem found. It seems that IIS proxy 5.1
plug-in with Weblogic 6.1 does not support the sticky load balancing. A sticky
service is one where a client sends its requests to the same instance and those
requests are not redirected to other instances. In production, two IIS match with
two Weblogic. Below is
#WebLogicHost=10.0.3.12
#WebLogicPort=8012
WebLogicCluster=10.0.3.12:8012,10.0.3.13:8012

Anyone have idea on out case?
Thanks,

My test was with 6.1 SP3.
The way to tell is by analyzing the cookie(JSESSIONID).
Perhaps the behaviour changed post SP1. I can't say for sure.

Is that entirely true concerning you don't need the persistence set to
replicated in the weblogic.xml to gain sticky load balancing?
The reason I ask was that in our situation sticky wouldn't work without
having the persistence set to replicated. This was with NSAPI and WLS 6.1
SP1. The weblogic servers were configured in a weblogic cluster. So..based
on this statement we should not have needed to set the persistence, but in
practice we did for it to work.

I just checked, and you are correct. You just need to have clustering
enabled in 6.1. You do not necessarily need to have persistence set to
replicated.
Of course, you won't get failover, but you will get the sticky load
balancing.

Why do we need to set session persistence to replicate in order to
perform
sticky load balancing ? There is no such requirement in WebLogic 5.1.
As
far
as I know, the IIS plugin simply interprets the value of the sessioncookie,
which should be embedded with the application server address, then
forward
the request to that particular application server.
We didn't use session replication in our environment because not allsession
variables are serializable.

The problem you mentionned in the other newsgroup post has been
fixed
and
will be in SP4. If you are in production or nearing production and
need
a
resolution now, then please open a case with support.
You should not need any other parameters to do the load balancing.
But
to
have the sticky load balancing, you must make sure you have session
persistence set to replicated for the webapp in question.
I'm not sure I am understanding your 3rd question.
In any case, my advice is to either wait for SP4 to bereleased(scheduled
sometime this month) or if you really need to go into production
soon,
contact support to obtain the latest IIS plugin.

Dear Eric,
Thanks very much for you kindly information, but we still have thefollowing issues
regarding the WL IIS proxy:
1. We have already tried the IIS proxy that comes with WL6.1 SP3.However, the
result from that version of IIS proxy is not satisfactory, as weexperienced cases
where the web page is not displayed correctly (as in
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.develo
per.interest.plug-in&item=994&utag=).
If there is any IIS proxy released after WL6.1 SP3, Could you
kindly
give
us
a pointer to the plugin?
2. In WL5.1 case, we are only required to have "WebLogicCluster"
parameter
set
to two weblogic servers in order use the load balancing features.
In
WL6.1, we
do not come across any additional settings required to support
load
balancing.
Is there any such settings required (e.g. in
config.xml,weblogic.xml,
application.xml,
etc?)
3. Does WL IIS proxy problem has anything to do with the version
of
the
IIS server/windows
versions that are using? we have already tried with IIS4 and IIS5
and
have
different
kinds of issues.
Thanks in advance for your kind assistance.

Jpeg and gif images are not fuzzy

How can I import jpeg and gif files so that they are crisp and not fuzzy? I have Lifecycle Designer 7.0

Look at the bottom of this page as well [http://carlback.blogspot.com/2007/12/apex-and-3rd-party-js-libraries.html]
Patrick Wolf
Carl,
the only drawback with #WORKSPACE_IMAGES# and #APP_IMAGES# is that it doesn't get cached by the browser. So each page request will transmit the hole file again. A caching option for the "Static Files" in the Shared Components would be nice :-)
About lazy loading with the #WORKSPACE_IMAGES#. I could think about a mod_rewrite rule which translates the additional file request of the JS library into a valid request for APEX.
Carl Backstrom
In 3.1 we emit a last modified header now for uploaded files so that should help with browser caching.
I wonder if anything's changed since then.

Firefox lags with youtube and .gif images

Everytime I try to watch a video on YouTube or even on other sites FireFox lags aprox every 10 seconds. Is annoying. The same thing happens with .gif images.
How can I fix this?
== This happened ==
Every time Firefox opened
== Always

This can be a problem with session restore.
Firefox stores session data every 10 seconds to make it possible to restore a crashed session.
If you have (security) software that interferes with that or have many tabs open then that cause cause a delay.
Some have reported that increasing the session store saving interval worked for them.

Proxy plug-in and WAP

Hello
I hava an IIS 5 with WLS proxy plugin configured on a win2000 server.
This machine has a real IP address to be accesed through the internet.
It proxies to a WLS 7 sp3 linux with no problem at all.
But, it does not proxy WAP content (wml). I mean, my webapp JSPs that
write the wml content.
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN"
"http://www.wapforum.org/DTD/wml13.dtd">
<%@ page contentType="text/vnd.wap.wml" %>
<wml>
</wml>
I have a simple menu on a wml page hosted on IIS. I can browse this menu
with no problem at all on my Nokia 3320..
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"

</card>
</wml>
When I choose the option that references to WLS (proxing by path /wls),
I get the error "Unknown file format" on my cel phone. This does not
happen with Nokia Toolkit Software.
I have full debug log configured and nothing gets registered. Seems like
the proxy plugin is not even reached.

WebLogicPort=7001
WlForwardPath=/wls

WLLogFile=C:\beaproxytest\proxy.log
ConnectTimeoutSecs=5
ConnectRetrySecs=2
If I access an html page on the WLS webapp, proxy plugin works fine. The
IIS and WLS web.xml have all MIME Types correctly set.
Can this be a proxy plugin issue?
Please help
Ricardo

The answer is that yes, in general you can use the same Web Server plug-ins across WLS versions. To answer specific questions, you should refer to our supported configurations documentation, such as:
http://e-docs.bea.com/platform/suppconfigs/configs103/103_over/add-ons.html
Note that over time new versions of Web Servers are released with older versions desupported. As a result newer versions of WebLogic Server may no longer support old Web Servers that were supported in older versions of WebLogic Server. But if you are using a current Web Server plug-in, on a Web server that is supported across your WebLogic Server versions, then yes you should be able to use the same plug-in across the WebLogic Server versions.

Effects Plug ins and Sample Image expression

Hello guys,
I have a small problem with the sample Image expression and effects affinity.
I build an effect similar to the autolevels effect. It scales up the gray levels of a picture. Really simple effect.
Then I try to get the color at some point of my layer.
So i add a Point effect, a color effect from expression control.
Then I put an expression to update my color parameter :
sampleImage(effect(Point));
this does work sometimes and not other times. I move the point and the value becomes incorrect... emptying the cache sometimes clear the problem but not all the time.
I have some random values sometimes too.
If I precomp my layer, then no problem, I get the right result.
It seems there is a synchonization problem between my effect and the expression evaluation. It seems to be evaluated before my effect computation is finished. Maybe i m not sending the right out flags or something like this?
I tried with the standard autolevels and the color is correctly updated....
If someone has any ideas that could help me.
thank you for your help in advance.

Dear Shachar,
Sorry again for mispelling your name so many times.
I m back to the question of sample image.
In prerender, i do like in the samples (Shifter, SDK Noise). I
realized that the behavior of the samples in the sdk is also
erroneous.
The color returned by sampleImage is randomly the color
before the effect application, and sometimes after the effect application.
It seems that SmartyPants sample is doing it correctly, so i have to check it out.

Hardware Load Balancers and Cluster WebLogic Proxy Plug-in setting

Documentation states that we need to enable the Cluster WebLogic Proxy Plug-in setting when there is a proxy plugin or HttpClusterServlet configured.
We used to have Weblogic Proxy plugin and the setting is still there, also the proxy was replaced by the hardware loadbalancer. Everything works normally and no one complained, but I would assume that WebLogic Proxy Plug-in setting should not be applicable any longer.
Is it possibly harmful to have that setting there? Does it mean that the loadbalancer emulates WebLogic Proxy Plug-in and also need this set?
Thank you

The Weblogic Proxy Plug-in Enabled flag only affects the behavior of a WL proxy module (such as if you were using Apache to proxy to WL via the mod_wl.so module). The value controls what IP address is returned when you call request.getRemoteAddr() from your application. If not enabled, you will get the IP address of the web server that proxied the request. If enabled, you will get the remote client IP address (instead of the proxy IP address) facilitated by the WL-Proxy-Client-IP header. If you are no longer using a plug-in module, the setting will have no affect. Hope this helps...

Color issues w/ .png and .gif files in CS5.5 Live view

Hi All,
I am having a bunch of trouble with my .png and .gif image files in Dreamweaver CS5.5. In Dreamweaver's design view everything looks fine but when I preview my pages in Live View or in a browser the colors in my .png and .gif files are way off. All my images are designed in RGB.
Any info anyone has to offer will be greatly appreciated. Thanks!

GIFS contain a maximum of 216 colors (web safe palette)
PNG and JPG can contain 16 million colors (true color palette),
When you say the colors are "way off" we don't know what you mean.
Can you post a link to your web page?

Efficiency of decoding and displaying image files?

BRIEF SUMMARY
My question is this: can Flash Player download JPG and GIF
files from a server and rapidly open/decode them, ready for
display, efficiently and
entirely 'in memory'?
Would Flex be a good choice of language for developing a RIA
that needs to continually download lots of JPG and GIF images
on-the-fly from the server and render them on the screen? I *don't*
want my application to thrash the hard disc.
BACKGROUND
I am designing a 'rich' web app, and I'm investigating
whether Flex is the right tool for the job.
Although Flash's animation features are an obvious selling
point for implementing my user interface, I also need to do some
server-side rendering. What I want to do is perhaps a little
unorthodox: I will be generating lots of GIF and JPG files on the
fly and these will be streamed to the client (along with other
application data, e.g. in XML format) to update different parts of
the on-screen document. In need this to happen very quickly (in
some cases, creating the effect of animation).
It happens that JPGs and 16-colour GIFs will be, by far, the
most efficient formats for streaming the images, because of the
nature of the application. I could of course send the images in
some proprietary format, geared for my application, but presumably
decoding the images would be slow as I would have to implement this
myself in ActionScript, and so I would be limited by the speed of
Flex 'bytecode'. (I realise Flash is a lot more optimised than it
once was, but I am hoping to see a gain from using image formats
that Flash natively understands!)
Naturally the internet bandwidth should (in principle) be the
bottleneck. However, assuming I can get my image files to the
client on time, want I want to know is:
how efficient is Flash at loading such files?
Bearing in mind that I'm not just displaying the occasional
image -- I will be doing this continuously. Most of the images
won't be huge, but there will be several separate images per
second.
The image files will be a mixture of normal colour JPGs and
4-bit colour GIFs (LZW-compressed). I know that Flash natively
supports these formats, but depending on how Adobe have implemented
their LZW/Huffman decoding and so on, and how much overhead there
is in opening/processing downloaded image files before they are
ready to 'blit' to the screen, I imagine this could be pretty fast
or pretty slow!
If my client only has a modest PC, I don't want the JPG/GIF
decoding alone to be thrashing his CPU (or indeed the disc) before
I've even got started on 'Flashy' vector stuff.
I'm new to Flash, so are there any 'gotchas' I need to know
about?
E.g. Would it be fair to assume Flash Player will do the
decoding of the downloaded image entirely 'in memory' without
trying to do anything clever like caching the file to disc, or
calling any libraries which might slow down the whole process? It
would be no good at all if the images were first written to the
client's hard disc before being ready to display, for example.
Further, if I'm doing something a little out-of-the-ordinary,
and there is no 'guarantee' that images will be loaded quickly,
what I'm doing might be a bad idea if a later version of Flash
Player may (for example) suddenly start doing some disc access in
the process of opening a newly downloaded image. So, while I could
just 'try it and see', what I really need is some assurance that
what I'm doing is sensible and is likely to carry on working in
future.
Finally, I imagine JPG/GIF decoding could be something that
would vary from platform to platform (e.g. for the sake of
argument, Flash Player for Windows could use a highly-optimised
library, but other versions could be very inefficient).
This could be the 'make or break' of my application, so all
advice is welcome! :) Thanks in advance.

You need a servlet/jsf component to render the image in the response.

Links in JPG & GIF images.

Hello board,
I'm making some JPGs & animated GIFs for my website, and my CMS allows images to link to only a single link; e.g. it
links the whole image. Is it possible to embed multiple links in a single image THEN upload to one's CMS? If so, how?

Marian Driscoll wrote:
JPG and GIF image files cannot contain even a single link. Links are only made through HTML.
You can slice the image (see Photoshop help on 'slicing') and then apply unique links to each slice in the CMS' WYSIWYG editor.
You can also manually enter a HTML image map for a single image file if your CMS allows raw HTML and does not filter that type of input.
Or you can use Dreamweaver.
