Client side paging with jstl or xslt
Is there any way to provide client side paging with jstl or xslt/xpath. I have a jsp page with a limited amount of data, say less than 30 rows of data. I want to display 10 rows at a time. The data is returned to the page in xml format and I am currently using xslt to display the data (currently displays all rows on the page). I am looking for a way to update my xpath variables so I can provide paging capabilities. Is there any way to get the information from the request from the jsp to the xpath variables? Or does anyone have any other suggestions for implementing client side paging using either xslst - xpath or jstl? Thanks Vic.
I am loading the entire xml stream in the client and formatting using xslt. I only want to initially display 10 rows. I would like to implement client side paging. Is there any way to communicate with the xpath variables? Javascript?

Problem in creating client side PDF with image using flex and AlivePD
I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
AtishayI am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing? -

How to implement a client side map with ObjectImage control?
We need to implement a client side map with an ADF Faces ObjectImage control. In the code below, the JSF Faces GraphicImage contol does support a client side image map using the usemap property. However, it appears that the ADF Faces ObjectImage control does not support a client side map. Is there someway of implementing this functionality in an ObjectImage control?
<h:graphicImage url="/images/map-usa.gif"
usemap="#m_mapusa"
binding="#{backing_map.graphicImage2}"
id="graphicImage2"
style="border-style:none;"/>
<af:objectImage source="/images/map-usa.gif"
binding="#{backing_map.objectImage2}"
id="objectImage2" />
We could use the Graphic Image control except we have a problem by mixing a JSF GraphicImage control in the same table with a variety of ADF Faces controls in that when a user clicks on the GraphicImage, then the browser windows scrolls down to center the GraphicImage control. A user then needs to scroll back up to see the rest of the page. If an ObjectImage control is used with an onClick action, then the page does not scroll, which is what we want. So if we can figure out how to add a client side map to an ObjectImage control we would get the desired results.
An alternative might be to use a server side map with the ObjectImage control. But our question here is how to implement the existing client side image map in a backing bean. As the following map code shows, not all image map areas are rectangles - some are polygons.
<area id="_state_05" href="#"
shape="rect"
coords="681,38,702,50"
target="_self" value="VT" alt="Vermont"
onclick="javascript:getDtl(this);"/>
<area id="_state_06" href="#"
shape="poly"
coords="221,442,209,436,209,418,191,403,155,382,116,367,101,370,98,364,
122,355,158,367,203,388,212,394,242,427"
target="_self" value="HI" alt="Hawaii"
onclick="javascript:getDtl(this);"/>Hi,
Any news about that issue, we are also interested in any solution.

Client side playlist with dynamicaly streamed items possible?
Hey,
is there a way to define a client side playlist like this:
ns.play( "stream1", 0, 30 );
ns.play( "stream2", 10, -1, false );
ns.play( " stream3", 0, -1, false );
ns.play( "stream4", 30, 120, false );
but instead of a single videofiles for each playlistentry use dynamic streaming?
I know how the DynamicStream class is working and how to set it up but i can't find any information if it is possible to combined those two techniques.
Thanks for any suggestions.Yes upto a certain extent you can achieve it, see below approach if it suits you. You can have playlist as xml file and each video tag will represent single item in playlist. So suppose you have xml file with video tags as below:
<videoList vodurl="rtmp://localhost/myapp">
<video>
<label>flv:stream</label>
<data>stream1,stream2,stream3</data>
<bitrate>100,200,350</bitrate>
</video>
<video>
<label>mp4:stream</label>
<data>mp4:stream1.mp4,mp4:stream2.mp4,mp4:stream3.mp4</data>
<bitrate>100,200,350</bitrate>
</video>
</videoList>
Then you need to create dynamic stream item("dsi") as below for each video tag and create array of "dsi".
var dsi:DynamicStreamItem = new DynamicStreamItem();
dsi.addStream( "mp4:stream1.mp4", 100);
dsi.addStream( "mp4:stream2.mp4", 200 );
dsi.addStream( "mp4:stream3.mp4", 350 );
ds.startPlay( dsi );
Then iterate each item of array, while you are playing first item of array then based on netstatus messages like "NetStream.Play.Complete" you can decide to move on to next item in array. So in this way you can create client side playlist.

Hi everyone. I'm new at the forum, a begginer programmer and I'm apologize for my english cuz is not very good ;). I'm making a project using only JSTL, I can't use the JSP embedded code, only JSTL, and a postgreSQL DB. Writing the paging I made the next code using only the JSTL and submit buttons which works very good.

Benefits of Client Side Monitoring with SCOM 2012R2?
I'm working on the architecture for adding SCOM 2012R2 to our Windows network. Right now we use SCCM 2012R2 and SCEP. I'm trying to determine whether I should include our workstation computers as part of this or only servers. We won't
be doing Application Performance Monitoring (APM). So what would be the benefit of putting the SCOM agent on the workstations?
# When I wrote this script only God and I knew what I was doing. # Now, only God Knows!Hi,
As it was mentioned by Yan Li_ first thing to do is the proper planning and comparing all pros and cons of SCOM client monitoring, depending on numbers of agent\agentless servers\workstations to be monitored. With a large number of agentless monitored
clients, it makes sense to have a separate SCOM infrastructure.
As well, please look at this links:

Client side validation with submit button in another region
Hi,
I have two regions, one containing a form with input texts for the user to fill in, and another region with a command button. A few of the input fields use the ADF "required" validator.
My problem is that when I click the submit button, and it does some logic to commit the form to a data base, even if the validator triggers and says that one of the required fields is empty, all the other fields get committed, except the ones that are empty. They get the last valid value.
What I want is the button to trigger the ADF message that doesn't allow the user to continue with the update. This doesn't happen though.
Anyone have any ideas? If you need a more thorough explanation, please let me know.Regions work as indipendent pages.
Yet if submit buttons are partialSubmit="false" then both regions (pages are submited).
Still there is a bug when commiting data:

Having problem with client side Authentication.
Hi,
I am haveing a problem enabling client side authentication with SSL on
weblogic 5.1.
I have set up the .properties files as explained, however it appears
my client is not sending a certificate back to the server. The same
client however works perfectly (using the same keystore file) with a
sample ClassFileSErver webserver from the jsse distribution. (the
client is a very slightly modified version of
SSLSocketClientWithClientAuth sample that comes with Jsse)
Below I've included a section of the debug dump from the interactions.
The only other difference I can see is the cipher suites offered by
the servers.
Weblogic offers type 0 or 9, and agrees on type 9
(SSL_RSA_WITH_DES_CBC_SHA), whereas ClassFileServer offer type 0 or 5
and settles on type 5 (SSL_RSA_WITH_RC4_128_SHA).
I am using the same keystore for both examples. Both servers request
an RSA client cert.... I'm out of ideas.
Any help would be greatfully received.
Cheers,
Keith

Did you read this article:
https://wiki.sdn.sap.com/wiki/display/BSP/Using%20Proxies
This explains how to properly setup the HTTPURLLOC table.
In your case you should have entries that look something like this:
40 HTTP * <internal host name> <https port>
50 HTTPS * <external host name> <https port>
In addition you need to run the report to determine if the proxy configuration is setup properly. The URL should be run with the

Hi all,
I have an RMI server and a number of clients that run on different machines. What I need to do is, implement the "observer" pattern. i.e.
in my case, not only the clients call the server, but also the server
must notify the registered clients when its state changes.
For that purpose, I suppose, that my clients must also be RMI servers.
My first question is, is that true what I suppose? Is there any other
way to implement asynchron client side callbacks with RMI?
My second question is, if it must be done so (clients are also RMI servers), how can I implement this? Server needs client interface jar
file, ans client needs server interface jar file at compile time.
(Important: I do not use any HTTP server from which I can load _Stub
classes at runtime)
I don't like this architecture at all and therefore think that there
may be better solutions. One solution may be to poll the state of the
server from the clients periodically, so that there is no need for
callbacks. But that is also not the perfect solution for me.
Can someone suggest anything else?
Any idea will be greatly appreciated!
Thank youHello guvener
Some time ago, I did exactly what you are thinking about. Here was the strategy.
1. There was a server program, sitting (obviously) on the server machine, where rmiserver was running. The server class had only a single public method for the calling routines to call.
2. That public method took, as a parameter, a transaction request. One possible transaction was, "Here is a message for another client." Another possible transaction was, "Listen out for a message for me." For example, a client would call the server with the "listen" transaction or with a "here's a message" transaction.
3. When the calling method requested a "listen" transaction, the server would enter a "wait" state until it received a message for that particular client.
4. To prevent blocking, there were three specific strategies:
(a) The client would call the server with a "listen" transaction in a separate thread.
(b) There was a "cancel" transaction that would allow a client to cancel its "listen" transaction with the server.
(c) There was a "close-down" transaction that would allow the server to tell the clients their "listen" transactions had been cancelled, as it was closing down.
This requires thorough and careful planning. However, once the classes are correctly planned, this strategy is elegant and simple and leads to only a small amount of coding. It's also flexible, without any restrictions on how many transactions a client could request at a time.
Do be careful to synchronize where applicable!
I hope this helps. -
What is Sharepoint client side object model ?
What is Sharepoint client side object model ?
The client-side object model (CSOM) provides client-side applications with access to a subset of the SharePoint Foundation server object model, including core objects such as site collections, sites, lists, and list items. As described in Data Access for
Client Applications, the CSOM actually consists of three distinct APIs—the ECMAScript object model, the Silverlight client object model, and the .NET managed client object model—that target distinct client platforms. The ECMAScript object model and the Silverlight
client object model provide a smaller subset of functionality. This is designed to enhance the user experience, because it minimize the time it takes Silverlight applications or JavaScript functions running in a Web page to load the files required for operation.
The .NET managed client object model provides a larger subset of functionality for standalone client applications. However, these APIs provide a broadly similar developer experience and work in a similar way.
You can write both managed client object model code and JavaScript Client Object model code in Visual Studio. As an example, you can create a console application having managed client object model code. Similarly, you may create a Visual Web Part and have
JavaScript client object model code in it. The JavaScript client object model code can also be directly written inside the SharePoint Designer as well.
