Java mapping for Remove and Add of DOCTYPE Tag

HI All,
i have one issue while the Java mapping for Remove and Add of DOCTYPE Tag in Operation Mapping .
it says that , while am testing in Configuration Test " Problem while determining receivers using interface mapping: Error while determining root tag of XML"
Receiver Determination...
error in SXMB MOni

<SAP:P1>Problem while determining receivers using interface mapping: Error while determining root tag of XML: '<!--' or '<![CDATA[' expected</SAP:P1>
plz provide solutions
Thanks in advance.

Hi Mahesh,
I understand, you are using extended Receiver Determination using Operational Mapping (which has Java Mapping). And, there is an error message u201CError while determining root tag of XMLu201D, when you are doing configuration test.
Can you please test, the Operational Mapping (which has Java Mapping) separately in ESR, with payload which is coming now. It should produce a XML something like this [Link1|http://help.sap.com/saphelp_nwpi711/helpdata/en/48/ce53aea0d7154ee10000000a421937/frameset.htm]

If it is not (I Think it will not), then there is some problem in Java Mapping coding. Please correct it. Last option, if your Java code is small in length; you may paste it here, so that we can have a look at the cause of issue.

InterMedia Java Classes for Servlets and JSPs and Netscape

I am using the interMedia Java Classes for Servlets and JSPs to upload and retrieve multimedia data. I have found that it is much more performant in Internet Explorer (5.5) than in Netscape Communicator (4.7). In fact, I cannot upload images larger than 10K at all using netscape. However, the same image can be uploaded into the same application using IE. Is this a known issue?
Thanks in advance.

Hi,
We have successfully uploaded multimedia data in the giga-byte range (Quicktime and AVI files) at the same speed with both the Netscape (4.7n) and MS IE (4.n and 5.n) browsers. One thing we have noticed is that its very important to set the manual proxy settings correctly if you have an environment with a proxy server. If you don't, then uploads can go via the proxy server and, for some reason, that seems to take considerably longer. For example, suppose you are in the www.xyzco.com domain and are connecting to a host named webserver.www.xyzco.com, then specify webserver and webserver.www.xyzco.com (to cover both cases) in the "Do not use proxy servers for..." box in the manual proxy server configuration screen. Also, if you're using a tool such as JDeveloper that uses the host IP address in the debugger environment, then you also need to add the numeric-based (nnn.nnn.nnn.nnn) IP address to this list.
Hope this helps.
In order to better understand the variety of ways in which our customers are using interMedia, we'd be very interested in knowing a little more about your application, the interMedia functionality that you are using, and how you are developing and deploying your application. If you are able to help us, please send a short email message with some information about your application, together with any comments you may have, to the Oracle interMedia Product Manager, Joe Mauro, at [email protected] Thank you!

Why we have separate azure java SDK for linux and windows

I saw different links for downloading azure java SDK for linux and windows.
What difference does it actually have when java is platform independent? Or both are same jars?

Hi,
Thank you for your post.
It contains the same jar files.

[Java]Java Library for CVS and SVN

Hi!
I need Java libraries for my application. I want to manage repository CVS and SVN directly form Java code and not with a graphic interface.
I've found some SVN library(for example SVNKit) but I don't found any CVS library.
Can you help me?
Thanks,
Stefano.

Keep googlin'! They're out there! It's worth grabbing the source code for Eclipse or NetBeans or something, and digging about in there. If they're not using a third-party library to handle CVS, they've probably at least written their own. Nothing to stop you, for instance, grabbing part of the Eclipse Team bundle and using it yourself.
Question is: Why do you want to do this? If it's some wacky "self-checking in code", forget it.

Java applet for Facebook and similar

Hi there,
I have downloaded the latest version of Java available for my OS 10.4.8, it seems to be running ok (if a bit slow) when I try to upload batches of pictures, but after some time it says the upload failed.
the same happens when I try to use similar Java uploaders for other website, which is a real pain as I then have to upload my pics one by one!
Has anybody got any heads-up on this?
thanks

Ok,
I have done both verifications, and a longish list of permissions seem to differ from the original. Here's an example:
Verify permissions for “ Dani's HD”
Determining correct file permissions.
User differs on ./Applications/.localized, should be 0, owner is 501
User differs on ./Applications/Address Book.app/Contents/MacOS, should be 0, owner is 501
Permissions differ on ./System/Library/CoreServices/Dock.app/Contents/Resources/Widgets.wdgt/Images/s crollbartop.png, should be -rwxr-xr-x , they are -rw-r--r--
User differs on ./Users/Shared/SC Info, should be 0, owner is 501
Group differs on ./private/etc/authorization, should be 80, group is 0
Permissions differ on ./private/var/log/secure.log, should be -rw------- , they are -rw-r-----
Permissions verification complete
The privileges have been verified or repaired on the selected volume
Shall I repair the volume now?

JAVA Stack for consuming and providing Services with ABAP?

Hi Experts,
I would like to know if I need to have a Java Stack when I want to build a Web Application with Web Dynpro Abap and consume Enterprise Services from the Enterprise Service Repository. Additional own created services in ABAP should be provided. Is a Java stack necessary for that? Or is an ABAP Stack enough?
Thanks a lot for your answers?
Best regards,
Ingmar

Hi Ingmar,
You do not need a Java stack to build or run Web Dynpro ABAP application. Web Dynpro ABAP runs on ABAP stack.
Just to consume a web or enterprise service from Web Dynpro ABAP application, or any ABAP application for that matter, you do not need Java stack, either. NetWeaver Application Server contains a component called ICM (Internet Communication Manager) that enables the AS to play both as a service provider as well as a consumer.
The part about consuming Enterprise Services from the ES Repository is more complicated, though.
ES Repository is only a modeling tool. Services are actually implemented in the respective backend systems and then registered in central Services Registry. So, if the Enterprise Service you want to consume comes from an application that runs on Java stack, although I do not have any example of that handy, then obviously - Java stack is needed. This is irrelevant, however, if your question only pertains to the consumer part.
I hope this helps.

Java plugin for Firefox and Chromium just not working

Hi Arch Users
I have been suffering with the IcedTea-Web for a while now. My banking service (in their stroke of genius) use java on there online service. So a problamatic plugin means that I am not able to use the website while on Linux.
The issue is not specific to the bank's website. Doing the following is also problematic:
1. Go to www.java.com
2. Click on "Do I have Java?"
3. Click on Verify Java Version
4. Chromium does nothing after setp 3, Firefox has a small notification (bottom corner) saying Applet Started but nothign really happens (waited for 20min).
Searching the Forums, showed people with similar problems with an older plugin. An idea I did get was to use the latest branch and compile it. So I changed the PKGBUILD to download the latest using:
hg clone http://icedtea.classpath.org/hg/icedtea-web
./autogen.sh
./configure --prefix=${_jvmdir} \
--datarootdir=/usr/share \
--with-jdk-home=${_jvmdir} \
--with-firefox=/usr/bin/firefox \
--with-chromium=/usr/bin/chromium
So currentely my FireFox reports the IcedTeaWeb as: IcedTea-Web Plugin (using IcedTea-Web 1.4pre+r6e622e87010e). Unfortunately the issue remains.
Please can anyone suggest me a way to overcome this issue. Currentely I have to use VirtualBox to run a browser in Windows (very very painful)!
A while back I did contact the bank, informing them of the issue was met with a simple "We dont support Linux".
Cheers!
J

Java API for webcams and Electrical Engineering

Hi,
Does anyone know of and API's that allow access to:
- Webcams, so that you are able to monitor a webcam and access the images etc etc
- Electronic circuit boards, e.g. monitor hardware, such as a processing plant whereby you can monitor output, input etc
Basically a java interface to hardware, i looked at the javacomm api, but this only allows basic functionality as far as i am aware.
Essentially, i need to monitor production faciltiies interfacing to a java environment so that hardware can be controlled and monitored.
Any suggestions people ?
Thanks

The Java Twain API from http://www.gnome.sk is designed to connect to a camera (or scanner) directly from the java application. You can comunicate with the camera, snap images, save them, ...
If you just want to see how Java Twain works:
- java (1.2 or higher) has to be installed on your computer
- a scanner or camera has to be installed on your computer
- download the trial package from http://www.gnome.sk
- unzipp it
- go to the examples directory of the unzipped package
- doubleclick the runExampleShow.bat (for Windows) or runExampleShow.sh (for MacOS) file
This will pop up the Twain Source Selection user interface. There, all your scanners and cameras which do have a twain driver should be listed. Select one of them. The user interface of the selected scanner (camera) will appear. Confirm the scanning (you can set the scanning parameters first). The scanned image will be displayed in a separate window. To end the application, close that window.
Running different examples, you can test scanning with hidden UI, saving the scanned image, using ADF, ...
If there are any problems, inquire at the technical support [email protected], I am a member :)

Java Card for GSM and PKI

Hi,
I am researching the feasibility of a project that is basically a SIM card the will also do cashless payments and will be able to digitally sign transactions and/or documents.
Basically a Java card that has the following:
1. GSM functionality (i.e. compliant to GSM standards 1111, 1114 and so on)
2. Has hardware for PKI support (elliptic curve, for the shorter keys)
3. Supports PKCS, so PC-based interface can talk to the card (somehow) and ask it to sign documents
Is there a card on the market that can do this?
Unfortunately I could not dig much information what is on offer by manufactures.

Contact the sales departments of the manufacturers (Giesecke&Devrient (G&D) and Oberthur, and maybe also NXP). They will refer you to the distributor/reseller for your area, through whom you can establish an NDA with the manufacturer and get access to the specification documents.

Fonts in java apps for win and linux

Hi everyone.
i need to build an application mult-plataform, to run in windows and linux...
but i don�t know waht font i must use...the default font that java takes doesn�t exist in linux (dialog)...
waht font should i use in my app??
thanx

For going multi-platform it is easiest to stick to the logical fonts: Fonts named "Serif", "SansSerif", "Monospaced", "Dialog", and "DialogInput".
These fonts are guaranteed to exist on any platform, although their implementations may be different. If you use others then you'll have to figure out how to deal with cross platform issues.

Any idea?
