Help to find the correct technology

Dear all,
first of all excuse me for my bad english. I've to develop a monitoring system for our instrumentation.
What I want to do is:
an user starts to use an instrument controlled by a PC (Linux or Windows), set an experiment ad runs an agent giving it some information. The agent starts in background and when receive a request from a server, collects some information in XML format and return its to the server. The server write this information in a db. The server ask for information in regularly interval of time. The user can use a browser to connect to the server, authenticate himself and see the experiment status.
When the experiment is finished, the server send a kill signal to the agent and the agent kill itself.
I've an agent for each instrument.
Instrument <------> PC Linux/Windows (agent) <------ xml ------> Server (Java EE) <--- jsf/restful----> Client
I want to use Java EE for the server part, but I haven't idea how to write the agent or which technology I've to use to realize the agent and how create the communication server <-> agent.
Thanks a lot for your help.

That is going to take weeks at least and will probably require you to buy and study several books. But you can learn while doing, JEE is not one big thing, it is a collection of little things which can be used and learned separately. So you could focus on the RESTful side of it first for example.
Thanks a lot for your help.What help? You didn't even ask a question, you just made a statement that you need to do stuff. If you want help you'll have to make a start yourself first, which will be orienting yourself on what is available. If you are stuck choosing between different technologies, THEN it is time to ask for help.

  • Can someone please help me find the correct driver for my audio ca

    Hello, it's famke again...Still trying to find drivers.. My sound card is apparently also missing drivers... I've tried many drivers from different sites matching the information i've taken off the card...but for some reason i always get a big red slash through my audigy sound control panel after trying to install the driver and reboot my system... I'm convinced i haven't been able to find the correct driver... The information off the card is...Soundblaster Audigy 2ZS M:SB0350... If anyone can help out i would greatly appreciate this...Famke.

    I'm new to this, but I also had trouble for a while in finding and installing the right drivers. Eventually I got it to work with the link below. Follow the steps and select everything it suggests (I did and it worked for me). You might want to try it and see if it works for you too.

  • Need help to find the correct .MIB-file

    Hi.
    We are using some Nexus 7009 chassis on my work and a program called "SNMPc" that receives traps from our Nexus devices.
    The program do not have the new Nexus 7000 MIBs so we are only getting "pure text" from Nexus.
    We need to download the right type of MIB file so we can get a better understanding of what is happening on the Nexus.
    We can ONLY use ".mib" extensions but Cisco currently only offering ".traps", ".my" and ".oid" files what I can find.
    This is an example message we get:
    ciscoMgmt.706.0.1 [1] ifName.437260288 (DisplayString): Ethernet3/2 [2] ciscoMgmt.706.1.1.0 (Integer): 5 [3] ciscoMgmt.706.1.2.0 (Integer): 5 [4] ciscoMgmt.706.1.3.0 (Integer): 5 [5] ciscoMgmt.706.1.4.0 (Integer): 5 [6] ciscoMgmt.706.1.5.0 (Integer): 5 [7] ciscoMgmt.706.1.6.0 (Integer): 5 [8] ciscoMgmt.706.1.7.0 (Integer): 5 [9] ciscoMgmt.706.1.8.0 (Integer): 4 [10] ciscoMgmt.706.1.9.0 (Integer): 5 [11] ciscoMgmt.706.1.10.0 (Integer): 5 [12] ciscoMgmt.706.1.11.0 (Integer): 5 [13] snmpTrapEnterprise.0 (ObjectID): ciscoMgmt.706
    We can see that the trap name is: 1.3.6.1.4.1.56.12.1.1.0.1
    Can someone help me get the right MIB?

    Silly question but have your tried changing the file extension of the .my files to .mib  ?  I typically have to do something like that for net-snmp with Cisco MIB files...

  • Help me find the correct document please!

    (This is a repost - not sure if I posted it in the correct forum before)
    I'm just starting out with Java, on the J2ME platform.
    I've been reading about threads, such as this:
    http://developers.sun.com/techtopics/mobility/midp/articles/threading2/
    where it says:
    The Java runtime associates each live thread with an instance of java.lang.Thread.
    But on my API docs, which I downloaded (can't find them online) the Thread class isn't a HTML link, suggesting it's not part of J2ME. But all the example source code I've seen has it supporting "start", "run" etc.
    The docs I have were downloaded from the Sun site, and are in the same format as the regular J2SE 1.5 does (html files with 3 panes).
    Am i missing something? Where (possibly on a Sun webpage) do I get documentation about Runnable, Thread etc, related to the MIDP2.0 release.

  • X300 - Need help finding the correct internal DVD Burner

    I want to buy and install an internal DVD burner, which I am unable to identify on the Lenovo website.  The only internal Ultrathin DVD burners I find fit the x200 series, but nothing for the x300 series.  Frustrating.
    Mine is a Thinkpad x300, Type 6477, and S/N L3-xxxxx.
    Anyone able to help me identify the correct part number?
    Thanks!
    Moderator Note; s/n edited for members own protection

    . . . thanks for the part IDs, lead_org. . . . took your advice and searched ebay for both, but nothing surfaced. . . . so, I entered the parts numbers into Lenovo's Websales site and was unable to find any such part listings for sale anywhere . . . nothing. . . . then, I emailed Lenovo Websales about it . . . they promptly replied that the parts were not in stock, and that I could try purchasing from www.cdw.com . . . I can understand if Lenovo did not have them in stock, but that they would not even LIST the parts was weird. . . . this is a 1-1/2 year old machine . . . are the lifecycles for laptops these days so short that they are unsupported even this fast? . . . I did see a few other sites selling the replacement DVD as new (presumably) for US$300, but none were in stock. . . . if I have no other alternatives, is a DVD the sort of part that is durable enough to reliably purchase used? Thanks!

    I have checked the file "initDEV.ora" and spfile.In them the positions of control file are  "/origlogA/cntrl","/origlogB/cntrl" and "/sapdata1/cntrl".
    So I donot know why the process of DB13 cannot find the correct control file and search the file CTL1DEV.ORA.
    Because the correct control file could not been backuped,I can not restore and recover the database.
    What causes it?

    Anyone can help me?
    Thanks!

    Praveen,
    I had the same problem as Ryan and Gary on a new XI \ Oracle 10g installation and your suggestion did solve this.  It seems that when you run the first BRTOOLS based backup, Oracle tries to create a PFILE from the automatically generated SPFILE, but the DB user doesn't have rights to delete the SAP.ORA file.  Once you assign SAP_<SAPSID>_GOBALADMIN full rights to the Oracle folder, an updated INIT<SID>.ORA is generated and the default SAP.ORA is deleted on the next BRTOOLS backup run.
    Thanks for the tip.
    Rgds,
    Andrew

  • Adding/Deleting T codes to roles. Finding the correct roles to add/delete T

    Hi Folks
    I would like solutions to 3 questions.
    1) How do you Add/Delete transaction codes to roles (ECC6)
    2) How do you find the correct roles to Add/Delete these T codes
    3) Has anyone any documentation and or screenshots on Versa, the Compliance Calibrator.
    We are using single roles within composite roles.
    Useful answers will be rewarded.
    Thank you very much
    Mark W

    Hi Mark,
    Typically the functional team or organisational design team will specify the roles required and the transaction assignment to those roles.  By working with them, you can understand what part of the business processes the roles represent and get an idea about which transactions go in what roles.  They will also be able to advise if a new role is required id a transaction is missing.
    The allocation of tx to roles should only be approved by role owners or appropriate responsible resource, and they should stipulate exactly which roles those tcodes go into.  If you have not been involved in the role design then it is not appropriate for them to expect you to make those kind of decisions.
    All of the recent compliance calibrator docs are on the service marketplace, I'm sure that the basis team on your current project will either give you their OSS ID to let you download them, or alternatively will download the docs for you if they have concerns about sharing the ID.  From memory, if you have security certification, you should be able to get an individual OSS ID from SAP.
    There is some high level info available from www.sap.com/grc and a brief overview of an install of CC5.1 here: http://www.*********************/sox_sod/sox_sod.htm
    Hope that helps

    Not sure which "Name" you are looking for, but you'll find all of them here: http://www.alvestrand.no/cgi-bin/hta/oidwordsearch?text=Name&prefix=top. The most common one is, obviously, commonName (OID 2.5.4.3) at http://www.alvestrand.no/objectid/2.5.4.3.html. Hope that helps.
