Bonuses of EJB creating server that uses TCP/IP to read/write to hosts

I have created just Java application(not EJB) that uses Socket classes to communicate(read/write) via TCP/IP with connected clients.
I'm new in EJB technology. I have read about 150 pages of different EJB and AppServer manuals but haven't yet found any bonus of EJB for my task. What bonuses could I get if I will remake application as EJB? Please describe advantages in good explained examples.

You can make an empty server only with tpsvrinit that starts your client
listeners and a tpsrvdone that stops them. Be carefull with sharing ipcs
between processes, or your clients may get puzzled!!!
Another choice can be builting a custom WSL/WSH but I haven't done
this yet and I don't know exactly the troubles related with making them.

would have to be started seperately and would not take advantage
of the tuxedo restart facilities etc of a tuxedo service.

How to interface a tuxedo app with another application that uses tcp/ip socket messaging

How would you interface a tuxedo app with another application that
uses tcp/ip socket messaging? I have a vendor product that offers
a tcp/ip message interface, and would like to know how best to
integrate it into a tuxedo application. I could write a C application
that listens and accepts incoming request from the vendors application,
and then make a tuxedo client call to a service. But this doesn't

OEPE can't launch server that uses custom Security provider

I recently migrated a Weblogic 8.1 server that we had a custom security provider for, to 10.3.2. It works fine when started with the startWeblogic.cmd file but when I try to start it using OEPE in eclipse it starts fine and runs fine but OEPE reports that
"Unable to validate WebLogic domain.Please make sure the running WebLogic instance is an Administration Server"
When I look at the Error Log it appears that it thinks one of my custom security classes is not found. But the server is running fine, so it is fine, it's on the classpath via the use of the EXT_PREPEND_CLASSPATH environment variable.
I am running Weblogic 10.3.2 on Windows XP using eclipse Ganymede 3.5.2 and OEPE version 1.5.0.201003170852
Here's the Error Log:

I am also facing the same issue.
i am running my web service program on tomcat. the server is weblogic 9.1. I am trying to invoke the EJBs running on the server from the tomcat.
i am getting similar exception. anyone got a solution for this ?

Does anyone know what command-esc does in mavericks? Trying to create service that uses that shortcut but can't.

Created the service, tried to set command-esc as the shortcut but mavericks won't let me. I don't see anything else that uses it. command-option-esc is force quit, I know that. command-esc used to be to launch front row years ago. As far as I can tell it does nothing in mavericks yet I can't set it as a shortcut? *sigh* Anyone? Thanks.

Here is a list of keyboard shortcuts, but I don't see Cmd+Esc listed:
http://support.apple.com/kb/HT1343?viewlocale=en_US&locale=en_US
Also I found this on google, about Cmd+Esc being used to launch Front Row, but it is quite old information:

EJB-RMI server hang using IIOP

I have a java program that makes an EJB call using IIOP to an EJB hosted on a WebLogic server. The code is known to work in several environments, however when I deploy this to my production environment it hangs and appears to "lose" the reply from Weblogic.
Essentially, then the program makes an attempt to obtain the initial context, it sends a request to the Weblogic server, but then hangs.
Snooping the network shows that the request has reached weblogic and that weblogic has sent a sensible reply (which the client acknowledges).
From trussing the process I can see the program send the request (268 bytes of data written to a socket that matches with what I see in snoop), but the program then seems to be looping in ioctl and pollsys, I never see it read any data.
The last few lines of the stack trace show the process in an Object.wait (see code snippets).
The last call my code makes is to construct a javax/naming/InitialContext (see "context = new InitialContext(props);" in Code snippet)
Doing a "CTRL+\" does not show any deadlocked threads in the JVM.
Code Snippets:
The method in the code that it crashes in is:
* Helper method to obtain an initial context
private static void obtainInitialContext(boolean reload)
throws IOException
if (context == null || reload)
logger.info("Creating a new initial context as it either doesn't exist or needs reloading");
final String PROVIDER_URL_KEY = "props.orange.ProviderUrlKey";
final String CONTEXT_FACTORY_KEY = "props.orange.ContextFactoryKey";
try
String providerURL = ConfigurationManager.getConfigValue(PROVIDER_URL_KEY);
String contextFactory = ConfigurationManager.getConfigValue(CONTEXT_FACTORY_KEY);
if (providerURL == null)
logger.error("Could not find the property: " + PROVIDER_URL_KEY);
throw new IOException("Could not find the property: " + PROVIDER_URL_KEY);
if (contextFactory == null)
logger.error("Could not find the property: " + CONTEXT_FACTORY_KEY);
throw new IOException("Could not find the property: " + CONTEXT_FACTORY_KEY);
Hashtable props = new Hashtable();
props.put(Context.PROVIDER_URL, providerURL);
props.put(Context.INITIAL_CONTEXT_FACTORY, contextFactory);

P6 Web Access connection to MS SQL Server database using TCP Dynamic Ports

Hi,
I am attempting to install P6 Web Access. When I run the installation and do the database configuration I am required to input a port number into the Database Host Port field. I do this and no error is displayed graphically, but I get a connection refused error when I look in the web access log.
"com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect "
The dba is running the database on an sql server farm and does not want to apply a static tcp port to the Primavera database as this will interfere with his other databases.
The fact that it appears to be mandatory to input a host database port during database configuration, has me thinking that P6 Web Access requires that the database be set up with a static TCP port? Is this correct?
I searched the documentation about this but came away with nothing...
any help would be truly appreciated.
Andy

At my previous company we experienced a similar issue with P6 Web. Our P6 database was hosted on an Oracle RAC and when configuring the Web connection I was forced to point it to a single RAC server rather then allow it to utilize the cluster. If you have found a resolution to this I would be interested in hearing about it.

How to create executable that uses mathscript? (LabVIEW 8.2)

Hello all, I have a rather lengthy algorithm developed in MATLAB that needs to be ported to LabVIEW 8.20, with the restraint of having to execute my code in under half a second. If I use the MathScript node/window, I can get the code to run in ~100ms by compiling it in the window and then running the VI. If I don't compile the code before running it, it takes approximately 16 seconds each time I run it, plus some hang up time after it finishes, as if it is closing something. However, it seems that I have to recompile every time I load the project or close/reopen the MathScript Window. My first question is if there is anyway around this, like saving the compiled code to be used if the program is closed and reopened. But in the end, the whole thing must go in an executable. I saw that in 8.20 MathScript code can be built into executables, but the executable that results still takes 48 seconds to run each time. Is this unavoidable? In the build specifications, I've checked the Enable MathScript Support box, and included the code file in the Dynamic VIs/Support Files category and have tried all the options under Additional Exclusions in the build spec window. By compiling the code in the MathScript Window and clicking Save All in the Project Window, there is an option to save a VI that the script seems to have created, which I have also tried to include in the build but received the same results. Any help at all would be greatly appreciated. Thanks in advance,
Chris

Hi Janell, thanks for responding.
The exe does not run any faster if I run it multiple times. I've only
ever run it three times in a row, however, before giving up on that
build.
I've attached a zip of the project folder that includes the m file and
the project/VI files. The exe is also in there in the folder 'Cueing'.
I did make a simple MathScript program that added two numbers and it
ran fine, both using a function call and the MathScript window and just
putting the code in the MathScript node. Both implementations had no
problems, neither did the exe's using either method.
Thanks,
Chris
Message Edited by ChrisReeves on 07-26-2007 01:41 PM - Well, I don't know if I will be able to attach the exe since the site is timing out on me when I try to upload it. It might just be too big.

ACE failing server out using TCP health probe

We have a mix of ACE20s and ACE30s currently and I am seeing the ACE in both HW platforms failing out our servers sporadically after a sucessful TCP handshake. Here is the configuration:
probe tcp TCP-25
   port 25
   interval 25
   faildetect 2
   passdetect interval 90
   open 10
When I do a show probe TCP-25 detail I see the default recv timeout is 10.
I captured a trace between the ACE and the server. When the health probes pass I see a good 3 way TCP handshake, then 50ms later the server sends a SMTP 220 then ace from ace, fin ack from ace and graceful TCP termination occurs. When the probe fails I see a sucessful TCP handshake but the ACE sends FIN ACK 47ms after it sends ACK for the TCP connection. Server then sends ACK and ACE sends RST.
Shouldn't ACE wait 10 seconds in this example for server to respond after TCP handshake?

TAC/Martin Nash was very helpful in explaining this. The TCP 3 way handshake was sucessful, but the ACE sent a FIN ACK as expected, but after the server sent an ACK the server did not send a FIN ACK so the ACE marked it down. The health check not only requires a 3 way handshake, but a clean teardown of the TCP session.

When i click on firefox it says "couldnt initialize security component"... "check that this directory has no read/write restrictions"..."If you continue to use this session, you might see incorrect application behaviour when accessing security features"

i had a problem with firefox before saying that it was corrupted, so i restored it, and it fixed that problem. the actual browser still loads up but i havent used it just in case.

See [[Could not initialize the browser security component]]
Rename (or delete) secmod.db (secmod.db.old) in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case there is a problem with the file.

Trash bin icon that used to appear after reading a text changed to reply icon

this is bothering me a bit. After the upgrade to the new 10.3, an icon appears after reading a text. The icon that appears momentarily used to be a trashbin icon so i can quickly delete the read message but for some reason unknown to me, the icon has now changed from a trashbin icon to a reply icon. I would very much prefer the trashbin icon as compared to the reply icon and is there away to change it?? Thanks for any assistance provided!

For the email section the instant action icon is normal and shows a trashbin but in the sms account, the instant action is a reply button. i have gone through all the settings and doesn't seem like i can change anything for the sms account instant action.
Are you not showing TWO choices for each?
For email - trashbin and ???
For SMS - Reply button and ???
Can you make certain that you don't have the setting for Instant Action 1 as "None"?

Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please ck that this directory has no read/write restrictions and your hard disk is not full or close to full.

This is an Alert when I open the browser. It isn't functioning at all. I've cleared ample space on my C drive, but I cannot find the application's profile directory to check the read/write restrictions.

How do I allow users to create folders in a shared folder where we all then have read/write access to those new folders?

I have three users who need to access a particular folder on one of our other Macs. The folder resides on the desktop of that particular Mac and it is set as "shared" with all of our accounts set to access the folder. When a user creates a new subfolder in that shared folder, the permissions are instantly set to allow the creator read/write access but the other users are only allowed read-only access. Is there a way to set the permissions so that any new folder created in that shared folder automatically gives read/write access to all accounts who are authorized access to that shared folder?

You should be able to take the permissions you have set and "apply to enclosed items." I am trying to attach a picture of what this looks like so my apologies if it does not work.
Highlight your folder you want and go to File>Get Info or command+I and at the bottom where it has Sharing and Permissions, click the lock button to authenticate. Click the gear and click "apply to enclosed items". See if that works.

Failure When Deploying EJB Project That Uses Library Onto Glassfish

Hi,
I have a multi project application that I am developing and I am having issues testing it. I have set up a EAR, WAR, EJB, and two library JARs. The EJB contains classes that use components from the library JARs or implement abstract classes from the library JARs. I have added the library JARs to the compile-time libraries of the EJB. I then also added the library JARs to the libraries of the EAR. However when I then go to deploy the EAR onto the Glassfish server I get this error, displayed in the Glassfish log:

I am using these technologies:
NetBeans IDE 7.0 for Java EE
Glassfish 3.1
I did read that putting the libraries in this directory: <glassfish_home>/domains/domain1/lib may resolve the problem, however there must be a better way.
Any help would be greatly appreciated!

First of all, use a normal font when posting a question. This is just terrible to read.
You have multiple failures here. Did you actually read and try to understand the error?
java.lang.NoClassDefFoundError: com/foo/sdk/core/AbstractClassJava is not going to lie, this class is not on the classpath of the application. Either the jar is missing, the class is missing from the jar or you put the jar in the wrong place. Open up the ear using your favorite zip tool and check out its structure. What is the path to the jar inside it?
Also, open up the META-INF/manifest.mf file inside the EJB jar. Is there a class-path line in there? There shouldn't be!
A valid ejb jar requires at least one session, entity (1.x/2.x style), or message-driven bean. Apparently your EJB jar contains not a single EJB or MDB class. Did you forget some annotations perhaps?
Seems to me that your application compiles, but other than that it is very much broken.

Changing Application that uses FTP port 21

We have a Windows server that uses an OCR software that allows our printers to scan documents to our Mountain Lion server to a document management application (at least thats what we are trying to do). The problem is that the OCR software is sending it to an FTP share but will not let you specify the FTP port number. By default Mac uses port 21 and I know how to change that port to something else. I just need to know if there is a way to let another application take control of port 21?

Sure. Shut off the ftp server on the target system.
At most there can be one application listening to a particular TCP port. If you don't want that to be ftp, shut it off.
But I'd tend to doubt that'll help, here.
I'd be interested in learning a little more about how this OCR tool works and how this file transfer supposedly happens, as ftp is a paragon of insecurity and also largely incompatible with modern network security and firewalls, but this particular request for a changed-port seems quite unexpected.
The identity of the OCR software might help, as a look at the documentation would be interesting, too.

SAP ECC Interface w/ IDOC-XML using TCP/IP, HTTP, or FTP to 3rd-Party Syst.

I am trying to understand if the following interface options can occur (without the use of SAP PI or any other middleware):
Option 1A: Can I process an SAP ECC outbound IDoc in XML using TCP/IP to a non-SAP 3rd party system? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?
Option 1B: Can I process an SAP ECC inbound XML-IDOC from a non-SAP calling system that used TCP/IP? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?
Option 2A: Can I process an SAP ECC outbound IDOC in XML using HTTP to a non-SAP 3rd-party system? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?
Option 2B: Can I process an SAP ECC inbound XML-IDOC from a non-SAP calling system that used HTTP? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?
Option 3A: Can I process an SAP ECC outbound IDOC in XML using FTP to a non-SAP 3rd-party system? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?
Option 3B: Can I process an SAP ECC inbound XML-IDOC from a non-SAP calling system that used FTP? Can you please explain the reason for why I can or can NOT do this. If possible, please provide supporting documentation on how-to do this?

Hello Kirk ,
The answers for your question are:
Option 1A: Yes you can .you can use TCP/IP but you must have a middleware component for that such as BC/JCO .
Please see the link : [http://help.sap.com/saphelp_nw04/helpdata/EN/09/c88442a07b0e53e10000000a155106/frameset.htm]
Option 1B: See the link above.
Option 2A: You can use ABAP code :
[http://help.sap.com/saphelp_nw04/helpdata/EN/e5/4d3514c11411d4ad310000e83539c3/frameset.htm]
Option 2B: [http://help.sap.com/saphelp_nw04/helpdata/EN/90/4f3c2ec3c511d6b2b400508b6b8a93/frameset.htm]
Option 3A: Only with ABAP code :[Reg: FTP Connection;
Option 3B: See the link of Option 3A.
Good Luck,
Boaz
