How to read messages longer than network buffer size
The logic of my application is:
the client sends a request to the server and wait, in blocking mode, for its response.
The server can responde with strings longer than 64KB (size of their sending and receiving buffer size), so under the hood, can also execs more than one socketChannel.write
Nothing in the message says where it finish, nevertheless the client needs to assemble all in one big
string.
How can the client deal with this ? I'd like keep it as simple as possible (without using a selector)
any thoughts ?
thanks in advance
Your above post suggests that it can send more than one packet (even ignoring the 64k limit.)
In that case the data of the message must contain sufficient information. If not then the solution is not determinate.
Ideally what you should received is a message and not just data. The message defines it contents. So you know how long it is and maybe even when it ends.
Alternatively the data might contain something. For example if you are recieving well formatted XML then you can create a simple parser that just looks for the end tag. If it isn't well formatted, or at least you can not rely on that then it is much harder.

Spam_scan: not wasting time on SA, message longer than
So this is a bit strange... well to me it is.
The size of the spam emails seems to be getting bigger, so I increased $samail_body_sizelimit first to 512 and then 1024 (which I thought was 1Meg)
$samail_body_sizelimit = 1024*1024;
However, I'm still seeing this, which seems odd - to me:

How do I print more than one custom-size photo on a page in PSE 10?
I recently upgraded from Photoshop Elements 6 to Photoshop Elements 10. I make greeting cards, and on PSE 6 I was able to print two custom-size (6-1/2” x 5”) cards on each 8-1/2” x 11” sheet of photo paper. The option to print more than one custom-size card on a single sheet of paper is not available in PSE 10. I want to know how I can print more than one custom-size card (or photo) on a page in PSE 10?

How to send video longer than 1 minute?
I'd like to send some video to youtube that is longer than a minute. As far as I can tell, this is impossible...?
OR, if this cannot be done, can I edit my video down?
(sorry, I briefly searched this topic and didn't see anything right away).
Thanks!This is more than likely a carrier restriction. Carriers set their own limits and most set the limits at 300kb or 600kb. You could enquire about your carriers limit. With a fixed limit, the higher the resolution, the shorter a file you can send. I presume the iphone has a lower resolution option.

How do you determine ip and op buffer size on a 3550-12G
I have a Cisco 3550-12G switch and I want to check to see if the input buffers and the output buffers for port gi0/12 are the same size. Is there a simple way to do this, I tried using the show buffers command but I couldn't seem to find what I was looking for. Help!
Hi,
"The 3550 switch uses central buffering. This means that there are no fixed buffer sizes per port. However, there is a fixed number of packets on a Gigabit port that can be queued. This fixed number is 4096. By default, each queue in a Gigabit port can have up to 1024 packets, regardless of the packet size."

How to read messages in message pool from a java file
Hi All,
I want to read a message that is defined in a message pool of a webdynpro component.
This reading should be done from a java file present in the "src" folder.
How can I get the handle to the IWDComponent?
Or is there any other way?
Or is there any way of reading localized messages in a java file of a webdynpro component?
Can you kindly guide me out of this issue?
Thanks and regards
RBHello,
my approach is more simple: how can I read within component A the message pool of another webdynpro component B ? Component A has a usage relation to component B .
I tried this within component A:
<b>this.wdThis.wdGetBInterface().wdGetAPI().getComponent().getTextAccessor().getText("ANY_TEXT");</b>
I got the exeption:
<b>java.lang.UnsupportedOperationException: Embedded Components are black boxes. You should not access parts which are not in their interface</b>.
Is there any way to share message pools ?
Thanks

How to Read Message from JMS Queue using Business Service(ALSB3.0)
Hi,
My Project Set up is as follows(using ALSB3.0).
1>One Proxy Service with transport as HTTP.
2>The Proxy service is calling another Business Service.
3>The Business Service has transport layer as JMS.
So here the business service is posting Request Message into the JMS queue.
I want at the same time it(The Business Service) should listen to another queue and from there it should read Response Message and forward back to the caller proxy service.
Can any one help me regarding this...
Thanks in advance...

How to read message from Active MQ using OSB
Hi All
I want to read from Active MQ ( situated on another server) using OSB (11g). My condition is
Active MQ---> OSB---> DB Tables
I know how to use BPEL to do this but I need to use OSB to do this. Client which puts data to Active MQ also puts data ( like eventtype)to its header and on basis of header(eventtype) I need to route the message to proper tables. Please let me know how can I do this and if any step by step info is available for this ( I checked on many blogs but couldn't find any).
Thanks very much
Regards

How to embed URL (Longer than 60 Chars) into CRM-Web UI
Hello
i would like to have a textfield with an URL embeded into the Incident UI
So far i managed to create the Char-Field and fill it with the URL
Unfortunately the generated Fields are limited to 60 Chars, but i need 100 for the URL with all parameters to work.
At the Moment the URL is truncated to 60 chars which leaves the link unfunctional
Any Ideas would be appreciated.
Kind regards
RolfHi Rolf,
I build a simple URL shortener in our system similar to ABAP URL shortener
The concept is quite easy. You store the source URL in a table and use a unique short-id instead. In my case I use function GENERAL_GET_RANDOM_PWD to generate the id for a given length (e.g. aBcD3). In addition, I created an ICF node 'ID' with a handler class that passes the short URL (e.g. http://mycompany/id/aBcD3) to the corresponding long URL, which can be internal or external.
The other option is to split the URL path into string_table and store the last entry, like:
lv_path = server->request->get_header_field( '~path_translated' ).
IF NOT lv_path IS INITIAL.
SPLIT lv_path AT '=' INTO TABLE lt_path.
DESCRIBE TABLE lt_path LINES lv_lines.
READ TABLE lt_path INTO ls_path INDEX lv_lines.
lv_guid = ls_path.
ENDIF.

How to read messages from mqseries continuously by java?
Hi,
I'm sending messages to the queue of MQSeries.
Here my requirement is i have to write a java/jms program that should run at the back side and check the queue for every 5 minutes for messages.If any message exists in the queue the java/jms program should read the message and display it on the console.
If anybody has idea please reply it.
thanks in advanceHi!
You have many ways. You could define a cron on a UNIX box to make sure a simple command line app connects to the queue every 5 min and uses JMS API to read the queue and do whatever you need with the messages.
http://java.sun.com/products/jms/javadoc-102a/index.html
On the other hand, unless its critical to recover messages just every 5 min., you could create an MDB. Actually this is the best solution: a Message Driven Enterprise Java Bean is just a listener over the queue reacting instantly to every message received. The way to create and configure them depends strongly on your appserver and development process: an IDE as WSAD or something like that creates them very easily. The actual problem with these ones is to properly configure them on your appserver. However, all appservers will allow you to define a 'Foreign JMS Provider' or something like that pointing to the actual MQ implementation you have and define an activation specification on which to sit your MDB.
