How to use external microphone? L420

Hi,
I had a R61 before and it was easy to use an external mic in that as there were two ports,one for headphones and the other for mic. In the L420 however, it seems that there is only one port with a headset engraved on it. I suppose that means it's a combi port, both for headphones and mic. So i connected the mic,but all I could hear in my recording was whatever the "INBUILT LAPTOP" microphone could record,which was mainly noise. My connected microphone could not be recorded. Any help?
Thanks.

Hi arx
I also used to fight with L420 mic, but the external mic plugin never gave me a problem.
First I tried a normal mic (3.5 mm / mini stereo) (http://en.wikipedia.org/wiki/File:Audio-TRS-Mini-Plug.jpg) and did not work.
If I use my earphones with mic that has a 4 section plug the mic works without problem.
Maybe you need this kind of adapter.

How to use external microphone in combo jack?

Hello,
My notebook Pavillion 14-V042tx have this combo jack (input/output in one jack).
How can i use my external microphone with this combo jack?
When i inserting the microphone it won't recognize the device, but when the headphone / external speakers are inserted, it's doing fine.
Do i need cable audio splitter like this?
Or are there any settings to enable the external microphone?
Thx before.

exlinko,
If the hardware is working the 8.1 software should detect that the jack was inserted and allow you to listen to (audio -out) on one of the jacks and allow you to input (audio-in) on the other. Also the software should mute the internal mic and speakers. Good luck with M$ 8.1 software.

How to use external Microphone in Logic pro 8?

I am trying to use a condenser mic with interface (blue iclcle USB) and all I am getting is the internal mic. Does anyone know how to change this?
Thanks L

Hi Leza2unes,
Have you selected the device (blue ice USB) from within Logic itself?
Here are a few ideas to get you going. This is assuming that you have installed any drivers needed for the USB device you are using.
Logic Preferences> Audio> devices tab then, "core audio" tab make sure "Core Audio" is selected in the check box and that you see the "Blue Ice" (or something that relates to the name of your device)in the drop down menu next to the word "device".
Hope that helps,

How to use external Java API in Java Embedd inside BPEL

How to use external classes inside the BPEL in Java Embed Activity ? Any sample code availble ? Like i want to use log4j API inside BPEL.

No you dont have to change your startManagedServer.cmd/.sh everytime you need to have a Java Embedding activity. You only need it in case of using Log4J. As log4j requires a configuration xml viz log4j.debug.xml and log4j.dtd you need to let the soa managed server know about it. The best way to load this configuration files is using the JAVA_OPTIONS command during server startup.
Hope the explanation helps.

How to use external jars in NW2004

Hello Experts,
can i use the same approach mentioned in the below Weblog for using the external jars in NW2004.
/people/bertram.ganz/blog/2008/11/24/how-to-use-external-jar-files-in-web-dynpro-development-components
and if not then what will be the best way to achieve it in NW2004.
Please provide your inputs on above.
Regards,
Siddharth

Hi Sidharth,
If you are using web dynpro DC perspective then you need to follow the following points to use the external jar files in it.
1. Create a external library project.
2. copy the external jars in the library folder os the projects.
3.) Select all the jars from the u201CLibrariesu201D folder, Right click and then select Development Component and click on Add to Public Part
4.Select the first Radio Button (Provides an API)and give some nameto it.
5. Repeat the step no 3 but now select the second radio button other than as selected in step no 4.
6. Now build your lirary DC.
7. Now create a j2ee DC project.
8. ) Expand the node DC Definition and Right Click on Used DC. Select Add Used DC.
9. Select the External Library DC with build time dependency.
10.Right click on the J2EE DC and then select Development Component followed by Build
11. Right click on the J2EE DC and then select Development Component followed by Deploy
now you can use both the libary DC and the j2ee DC in your web dynpro DC as used DC.
But if you have created a web dynpro project only(but not DC) than you can directly add the external jars in java build path
hope this will help
regards
Narendra

How to use External Tables

Hi, I want to know how to use external tables? The procedure i follow for SQL*Loader in my shell script is:
Call the sqlldr
Check return code
If return code = 2. get count of records from bad file and exit.
If return code != 0 and != 2 then exit as fatal error
If return code = 0 then continue.
But i don't understand how to use external table as it is not invoked and does not have a return code.

Hello,
What do you mean alogrithim, do you mean to invoke external table as you invoke sqlldr? You can generate external table script from sqlldr and use it to load data but you might have to modify the table name and datafile name . You can see if any bad file generated from sqlldr and if yes then you can generate external table (using sqlldr) or based on your bad file. May be if you can list what exactly you want in bullet points, then it will be easier to suggest you.

Using external microphones with zen ne

How do I plug in an external microphone into my zen neeon? I plan to use bi-naural microphones. Can I use a preamp and an adapter? Is this even possible with my model?
Thanks
Nora

I'm sorry, but that's not really my area of expertise. If you are planning to use this for simple voice-recording you could try the Griffin iMic device which helps provide both pre-amplification and impedance matching between a mini-plug mic and a USB port for sound input. I've used it recording music from a boom-box to a MacBook.
The tech specs state that the audio line-level in port is:
Input impedance greater than 20,000 ohms
Input level: Max 2 V rms (+8.2 dbµ)
I would look for a mic that meets those specifications. MacSpeech.com has several microphone/headset recommendations for use with their Dictate and iListen voice recognition software. I would think that their suggestions would be useful.

How to use external libraries jar files in the composite application?

Can anyone help?
Thanks.

Hi,
My jar files consists only java classes and a manifest.mf. The files are compiled using jdk 1.4.2-b28. Will this be any issue?
It seems that if I ignore the error and continue step 7 which is to do deployment of the ear, the error given is
Cannot update it.
Caused by: com.sap.engine.library.bytecode.cf.CFException: Invalid constant pool tag, 60 at index 41.
Does anyone know what that mean?
Is there any sample that teach how to deploy external libraries as bundled library?
Thanks.

How to use external table - creating NFS mount -the details involved

Hi,
We are using Oracle 10.2.0.3 on Solaris 10. I want to use external tables to load huge csv data into the database. This concept was tested and also found to be working fine. But my doubt that : since ours is a J2EE application, the csv files have to come from the front end- from the app server. So in this case how to move them to the db server?
For my testing I just used putty to transfer the file to db server, than ran the dos2unix command to strip off the control character at the end of file. but since this is to be done from the app server, putty can not be used. In this case how can this be done? Are there any risks or security issues involved in this process?
Regards

Why would it not work?
As for getting the files from the app server to the db server. There are a number of options.
You can look at it from an o/s replication level. The command rdist is common on most (if not all) Unix/Linux flavours and used for remote distribution and sync'ing of files and directories. It also supports scp as the underlying protocol (instead of the older rcp protocol).
You can use file sharing - the typical Unix approach would be to use NFS. Samba is also an option if NTLM (Windows) is already used in the organisation and you want to hook this into your existing security infrastructure (e.g. using Microsoft's Active Directory).
You can use a cluster file system - a file system that resides on shared storage and can be used by by both app and db servers as a mounted/cooked file system. Cluster file systems like ACFS, OCFS2 and GFS exist for Linux.
You can go for a pull method - where the db server on client instruction (that provides the file details), connects to the app server (using scp/sftp/ftp), copy that file from the app server, and then proceed to load it. You can even add a compression feature to this - so that the db server copies a zipped file from the app server and then unzip it for loading.
Security issues. Well, if the internals is not exposed then security will not be a problem. For example, defining a trusted connection between app server ad db server - so the client instruction does not have to contain any authentication data. Letting the client instruction only specify the filename and have the internal code use a standard and fixed directory structure. That way the client cannot instruct something like +/etc/shadow+ be copied from the app server and loaded into the db sever as a data file. Etc.
