How to invoke different WAD Applications from external URLS

Hi
We have developed different applications (app1, app2) in WAD using templates and we'd like the following behavior :
app1 being called from http://www.aaa.com as app1 real url is http://hostname:port/sap/bw/BEx?sap-language=EN&CMD=LDOC&TEMPLATE_ID=XXXX
app2 being called from http://www.bbb.com as app2 real url is http://hostname:port/sap/bw/BEx?sap-language=EN&CMD=LDOC&TEMPLATE_ID=YYYY
www.aaa.com and www.bbb.com point of course to the same IP address in the DNS (same host)
Is there a way to properly configure the ABAP Web App Server to deal with this like Apache does through Virtual Hosts ?
Thanks a lot for your help.

In other words, how to develop several applications (BSP, WAD, ...) on the same app server ?
Each app should have its own URL without a "forward slash something" as follow :
app1 => http://www.aaa.com
app2 => http://www.bbb.com
appn => http://www.zzz.com
Apache permits it via name-based virtual hosts. It then allows multiple web sites to share on box and one IP address.
Thanks for your help.

How to invoke ADF custom application from existing R12 EBS application

Hi Guru's,
We have a requirement to invoke ADF custom application from existing EBS R12.1.3 application.
Is there any documentation provided by ORACLE or any online help on how to integrate/invoke ADF pages from existing EBS application?
And can we pass any EBS session level parameters like(user info, language, operating unit etc) to ADF layer while invoking the ADF application?
I have thoroughly searched the forums and got some info related to JAAS security links and all. but i am looking for exact integration specific steps.
Any help in this regard is a great help!!
Thanks alot for your help!!

Invoke one java application from another?

Hello,
Can anyone tell me how to Invoke one java application from another?
Suppose I have a small java application say, Hello.java which has its own main() method and
I also have another java application, say World.java which has its own main() method too.
What I want to do is invoke or startup World.java from Hello.java.
If possible kindly give code examples?

main is just a normal method so Hello can invoke the main method of World just as it would invoke any other method.

After a Lion clean install, how do I retrieve my data from external back-up? Following Apple advice for use of Migration Assistant did not work creating similar issues leading to clean install.

After a Lion clean install, how do I retrieve my data from external hard drive?
Following Apple advice I used Migration Assistant which crashed new system twice which is why I had to clean install Lion in the first place.
Is there a sure way of doing it?
I have only a few programs that I will have to install myself and that should not be a problem.
I just want my data, music and photos back where I can use them.

Time machine backups. I went to migration assistant a few hours ago and limited my selection to "users", no need for applications, settings and other files. Stuff started moving over at a fast pace but has now seemed to stall.
I will let it run overnight as there are lots of songs and photos as well as a few movies.
If that does not work, then I will go into TM and try restore. I have restored some things in the past such a mail files and it has worked well.
The Apple fellow at the store told me to go right into TM, he may have had a point. I'll get it eventually.

Re: How do I keep an application from being started morethan once?

Here are some quick ideas. None of them should be too hard to implement,
although each has some drawbacks.
1. Have a login server track who is logged on, and if there is already a
logon for a given user or a given machine, then deny the application
startup. The nice thing about this is that a user will not be able to have
multiple logins even by going to another machine. Then again, this may not
be so nice, and you also get a possible single point of failure on the
login server for which you will have to prepare.
2. Drop to the operating system, and get a list of processes for the client
machine. If the name of one of them matches the name of application that
is being run, then deny startup. This avoids a network hit, but requires
some OS specific code. Also, a clever user could change the name of an
executable to get around this. Note that a user could have another login
on another machine.
3. Write to a file on the local machine. You can hide the file in some
suitable place, and can also scramble some information so that a user
cannot get around having this file present by reading from the file at
startup and then writing to it. Based on the state of your application,
the file will have some scrambled information indicating if an instance of
an application can be started. If you retain the write lock (i.e. do not
close) the file for the duration of the application, you increase your
security at the risk of a confused user if the application gets terminated
without releasing the lock. Depending on the OS where the client will run,
this could be an issue. If you like this option, perform some experiments
first on all configurations of an example client machine to determine the
behavior. Again, this only works to prevent an extra login on a single
machine, not system wide.
If you are not concerned about your users hacking around too much and don't
care about a login on another machine, I would opt for some version of
number 3. Otherwise, I would venture number 1.

Yet another quick and dirty solution is to use local ExternalConnections.
This is a single instance per machine solution.
Example is attached.

Martin,
there are two ways to read your question
(a) no more than one instance of an application per machine
(b) no more than one instance of an application per "user"
now if a user has only one machine, and your system has "userids" and you
only want
one active "session" per "user" then the distinction is irrelevant.
However, many systems
let people share logins, so a token based thing enforcing one login will be
problematic.
The downside of #1 approach suggested by Curtis happens when a machine gets
hosed without "logging" the user off the security system, then they can't
get in until their ticket expires or a sysadmin gets involved. Should be
manageable, however. But this enforces one application
instance per user, unless you check both for the presence of an active
token for that user as well as the presence of a token tied to that
particular node name. Otherwise there is nothing to prevent the same user
from launching the app again and logging in as a different user. This is
definitely the best approach of the bunch, and can be adapted for either
(a) or (b).
Suggestion # 2 won't work unless the application is built as a compiled
client,
since the process name will be 'ftexec' and not the "name" of the
application. And it doesn't
prevent a user from launching the app from a different machine (or people
sharing logins). So again it depends on what you are trying to achieve.
#3 also only prevents multiple instances per machine, not necessarily by
user. Of course
most people don't have multiple machines. The point is that you may be
trying to
prevent your users from sharing logins. In which case the file thing won't
do it.
Some other ideas:
1. You could, however, enforce one application per machine using the
installed partition agent's ExecutingPartition instrument name. As long as
the user doesn't run the app in a different environment, you can have the
app check at startup time if there is another
ActivePartition running under the same InstalledPartition name.
(ActivePartitions are child agents
of InstalledPartitions).
2. use the ObjectLocationManager and bind a simple object into the naming
system using a naming scheme such as
/MyApplication/MyNode or
/MyApplication/MyUserId
the presence of either one would indicate that another instance of that
application is running on either that machine or that user. Of course
these have to be cleaned out, and subject to similar downside as
alternative #1. So you'd essentially be using the forte naming system as a
distributed lock manager (ouch).
3. Have the application remove the shortcut to launch it upon startup, and
recreate it when it is finished, or move it to a hidden place. There it
is - the worst idea I've ever come up with. Don't
do this!

John

If the applications were originally drag and drop installations you can simply drag them to the trash and empty. If they were installed by an installer there should be an uninstaller included. If you're not sure you should check with the software developer for instructions. In this case Google can be your friend.

There's Setup Assistant and Migration Assistant. The cleanest way to do it is Setup Assistant, but you only get that option once when you fire up a fresh install of OSX. If you're past that, you could reinstall OSX by booting with Command-R, or you could use Migration Assistant.

E51 - How to move pre-installed application from m...

Hi all,
I just purchased my E51 some days ago. The phone packaged with Advanced Call Manager pre-installed in microSD card. Now I want to use my 2gb microSD instead of 512mb from Nokia but I will lose the application if I take out the microSD card. How can I move that application from card to phone memory since I could not find the *.sis of that application.
Thanks in advance.

A new phone just includes the installers - you can choose whether to install on the phone or memory card.
However, you can still transfer the app to the newer memory card. Use a card reader, or connect your phone in "Data Transfer Mode", and copy ALL the content of the 512mb card to your computer - make sure that you include the hidden files too. Then copy over these files to your new memory card, again take care to copy the hidden files. That way, you will have the pre-installed software on your new memory card.
