CORBA using Java

I am trying to use java to connect to a CORBA Object and get an COMM_FAILURE Exception when I try to execute the follinwg line of code:
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
The object orb has been initialized with the following parameters:
props.put("org.omg.CORBA.ORBInitialPort", port);
props.put("org.omg.CORBA.ORBInitialHost", host);
orb = ORB.init(sArray, props);
The exception I get is:
Inside getMatchRef().
About to resolve reference.

Could not get reference
Unable to reference the Match Engine object.
The people whose CORBA object I am trying to reference tell me I am connecting to the correct server and port. although they said I need to pass in two ports, one being the Orbix port and one being the base port. What am i doing wrong??? Any help would be appreciated.

if your are using tnamesev, launch the tnameserver with "tnameserv -ORBInitialPort yourPort -ORBInitialHost yourHostName(not localhost)", and this might help

  • Book recomendations for CORBA using Java?

    I need to use CORBA communications between 3 different tools. Each tool should be written in Java. Each tool reside on different servers. Here is the communication flow of the tools:
    Tool A will pass data to and receive data from Tool B
    Tool B will pass data to and receive data from Tool A
    Tool B will pass data to and receive data from Tool C
    Tool C will pass data to and receive data from Tool B
    I did a search on "Java Corba" at some online book stores and there a many choices. Could someone recommend a book title that would work well here? Thanks.....

    Pure CORBA by Fintan Bolton (ISBN: 0-672-31812-1) is an outstanding reference, albeit very "heavy" as someone else said about another book previously in this thread. The book always gives C++ and Java examples; never one without the other (except for a chapter on memory management, but the topic is applicable only to C++). It can be difficult to use as a tutorial as it is very much written as a reference though.
    I don't have any recommendations for CORBA instruction-oriented books.

  • Problem with CORBA application deployed using Java Web Start 1_6_0.

    Java Web Start fans and experts:
    We have been using Java Web Start to deploy the client side of a CORBA-based application since the inception of Java Web Start ... including Java Web Start 1.0 right up through the present.
    With Java Web Start 1_6_0, we see evidence that Web Start is "tinkering with" the IOR that CORBA uses to communicate. In all previous versions of Java Web Start, independent of the JRE which the application uses, the stringified IOR have been the same size regardless of whether the application is deployed locally or via Java Web Start. With Java Web Start 1_6_0, the stringified IOR is much longer than the "real" IOR (again, regardless of the JRE used by the application itself). To me this smells like a bug in Java Web Start 1_6_0. Has anyone else observed this behavior?
    Here are some specifics .... I've run the same client application with various JREs both with and without Java Web Start as the deployment mechanism. The application was compiled and runs against servers that are running JDK 1_5_0_09.
    Here is the summary of my results from a Linux box running various JREs, various versions of Java Web Start, and also running as a non-JWS deployed application. I've listed the length of the stringified IOR in each case.
    JRE 1.5.0 non-JWS client: stringified IOR length = 344
    JRE 1.6.0 non-JWS client: stringified IOR length = 344 ... this, I think, excludes the JRE as the cause of these problems.
    Java WS 1.5.0, JRE 1.5.0 JWS client: stringified IOR length = 344
    Java WS 1.5.0, JRE 1.6.0 JWS client: stringified IOR length = 344
    Java WS 1.6.0, JRE 1.6.0 JWS client: stringified IOR length = 1568
    Java WS 1.6.0, JRE 1.5.0 JWS cleint: stringified IOR length = 1568
    In all cases, the stringified IOR length is determined by the service receiving the message and is always running JRE 1_5_9_09 and is
    always the same 344 characters in length UNLESS it was deployed
    using Java Web Start 1_6_0, in which case it in nearly 5 times as big!
    To me, it sure looks as if there is a problem with Java Web Start 1_6_0 to be adding so much to the stringified IOR. Note: it's hard to tell how different the underlying IOR is in the JWS 1_6_0 case because, unlike most other ORBs, the Sun ORB doesn't have a tool to extract the IOR into a human readable structure. However, I can think of no good reason why the identical application deployed using Java Web Start 1_6_0 should have a stringified IOR length that is different than that of the same application deployed in non-JWS form or should differ from the behavior seen in all previous releases of Java Web Start.
    Any clues or suggestions? Has anyone else observed this behavior?
    Thanks,
    John

    Hi.
    I got a different problem. My Corba application works in JRE 1.6, but doesn't works in JRE 1.5.X. I got an unexpected error and my console shows:
    getSubjectX500Principal NoSuchMethodError: java.lang NoSuchMethodError
    #### Java Web Start Error:
    #### null
    Can you help me?

  • Strange Corba performance problem using java 1.6

    I have a java server talking to java and C++ clients using CORBA and moved from java 1.4.2 to 1.6.
    Using java 1.4.2 for a large block of data, the client consistently refreshes in about 28-32 seconds.
    Using Java 1.6 the times vary between 19 and 135 seconds.
    After restarting the server all clients consistently take a simlar amount of time (usually between 32-35 seconds). But sometimes when the server is started the clients see a time between 19-25 seconds, sometimes between 50-55 seconds, and very occassionally over we see times of over 100 seconds.
    Once started, the server seems to pick up some setting or behaviour that causes it to run at a fairly fixed rate.
    We have tried adjusting the GIOP fragment and block size, which can change the performance, but no mater what size we use, we still see this strange behaviour where the server sometime runs in "fast" mode and sometimes in "slow" mode.
    The server side cpu usage is higher when it is in "fast" mode. Client side cpu is higher in slow mode. Amount of data transfered does not appear to change.
    Server runing on Linux RedHat Ent 4u5 - client Linux RedHat 9, RedHat Ent 4u5.
    I see a similar behaviour even when I run the client and server on the same machine.
    Any thoughts on where I should look next anyone?
    Write a simple corba server/client that shows the problem.
    Investigate Other Corba networking settings
    measure the client server packet size and performance.
    Thanks

    3 forums is not enough to post this in, I mean, it is such a HUGE problem,
    you should post it in at least another 20 forums.

  • How can I change java.policy at runtim on client machines using java webst?

    Hi,
    I have to change java.policy to launch my application through webstart to provide one RuntimePermission "permission java.lang.RuntimePermission "getClassLoader";"
    Its because of a bug in java bug "_http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4809366_"
    So, my problem here is, how can I do this dynamically on each client machine's java.policy.
    I have spent time on this and found some alternatives
    1. Specifying an Additional Policy File at Runtime by launching application "java -Djava.security.manager -Djava.security.policy=someURL SomeApp"
    Please refer more on this "http://docs.oracle.com/javase/6/docs/technotes/guides/security/PolicyFiles.html"
    But, here the problem is, how can I do this using webstart (expert.jnlp) file even though I have the "java-vm-args" tag, its not supporting this argument.
    Please refer "http://docs.oracle.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#security";
    2. Implementing the Policy in code.
    But, not sure how to do this..
    How can I grant the runtime permission on every user's machine dynamycally?
    Here are some background details on this:
    I am using java6 and weblogic 10.3.3.
    Here is thing that I tried,
    My application downloads a few jars to the client machines using java webstart and then it will get the initial context using the t3 protocal. The jars include wlclient.jar and ojdbc6.jar initially.
    The problem here I was facing, when I tried request a bean, it is giving me the following exception in the client logs.It is requesting one state less session bean and I checked the server logs as well and the bean has returned the expected values properly.
    But here I observed one more thing, before this request, one session bean(state less) has been requested successfully.

    The same is working in some other machine which are in different network. So, I have replaced the wlclient.jar with the wlthint3client.jar.
    After replacing this jar I was getting the below exception in client logs while requesting a state less session bean.I also checked whether the request is reaching the server (bean) or not, but its not reaching the server.The problem is same at all the machines irrespective of the networks.

    I have tried one more thing, I have taken all the required jars to one of the client machines and executed the main class (by setting the required class path) from cmd using java instead of javaws. Surprisingly, its working fine with out any problem using the wlthint3client.jar.
    I also tried the same, by placing wlclient.jar using java in the same way(from cmd instead of javaws ), but I was facing the same exception while requesting the second session bean and found the same above exception in client logs.
    To resolve this, I come across the java bug that I have given earlier "_http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4809366_".
    In that page, I found a work around for this; suggested by bea to add the Runtime permission "permission java.lang.RuntimePermission "getClassLoader";" to the clients java.policy
    So, please suggest me a way to resolve this problem.
    Please suggest me if you have any other solutions for this problem.
    Thanks in advance :)

    I still think your problem is nothing to do with that ancient non-bug and that you should be looking elsewhere. You might be lucky and find someone here who can say "Ah, I know what that is" but I doubt it because since Oracle took over Sun this site has gone down hill big time.

    You must not have the complete IFS_BASE_CLASSPATH defined in your CLASSPATH environment variable. The easiest way to do this is to type ". ifsenv.sh" on Solaris (or run ifsenv.bat on NT). Then you can invoke java like this:
    java -classpath $CLASSPATH:$IFS_BASE_CLASSPATH ...
    (your standard JDK classes should already be in the CLASSPATH; append our classpath to it)

  • Using Java, How can I Update, Add, Delete nodes in XML Files.

    Hi,
    I want to store the student record (like Name, Age, school name, total mark etc.,) as nodes in the XMLfile. Also I should able to Update, Add, Delete any nodes (student record) in the XML file. How can I achieve this...using Java
    I am able to read the content of the xml file using xml-parser. But my problem is
    updating the xml file.
    pls suggest some solutions or links with " example source code"
    Thanks :-)

    There are 2 kinds of XML parsers : SAX and DOM. DOM seems to suit your need. You can use JAXP APIs to add, delete or change nodes or attributes.
    http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/TOC.html provides contents that would satisfy most of the needs.
    To save a DOM modified XML file use java IO APIs to write to the same file from which it was read using a Document object ( doc.getNodeValue() ).

  • ORA-04030: out of process memory when using Java Stored Procedures

    Hello,
    I have a problem using Java Stored Procedures in Oracle 10g.
    My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
    There is a scheduled job which calls the Java Stored Procedure every x minutes.
    No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
    ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
    ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
    The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
    java.net.ConnectException: Connection refused
         at java.net.PlainSocketImpl.socketConnect(Native Method)
         at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)

    Can be a problem with JVM threading under Oracle ?

    The server prcess failed to allocate more memory for large objects ( in Oldspace).
    If you Google ORA-04030, you will see several recommendations to work around this.
    The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

  • Using Java Access bridge (Accessibility) with oracle forms 6.0 client

    I'm trying to use JAB (java Access bridge ) to capture events in oracle forms 6.0 client .
    I've a Jinitiator 1.1.8 and JRE version 1.4x
    I've configured JAB as per the installation guide . However the events don't surface in Java Monkey .
    Has anybody encountered similar issue ? what is the solution for the issue ??
    Also on one of the forums I read Jinitiator 1.3x and above is automatically recognised by Java Access bridge .
    For jinitiator version less than 1.3 manual configuration is required . however I haven;'t been able to find any on the oracle forms KB
    Also here is the excerpt from the link http://www.oracle.com/us/corporate/accessibility/faqs/index.html
    Q: Are there special steps for using Java-based applications with assistive technology?
    A: If the Oracle application is written in Java, such as JDeveloper or Oracle Forms (runtime), customers must first install the latest version of Sun's Java Access Bridge. The Java Access Bridge provides the integration with screen readers such as JAWS or SuperNova that support Java. You just download the Access Bridge and install it. Sun's AccessBridge 2.0x recognizes Oracle's JInitiator 1.3x and above so no manual configuration steps are necessary. The Access Bridge is available from: http://java.sun.com/products/accessbridge. At the time this document was written, Access Bridge 2.0.1 is the most current publicly available production release; Oracle recommends upgrading to this version. Sun's AccessBridge is bundled with Oracle Universal Installer (OUI) and can be found in the Java Runtime Engine (JRE). More information for configuring such products is in the respective product documentation, or on http://www.oracle.com/us/corporate/accessibility/products/index.html.

  • Unable to run my application using java web start

    i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
    -jsdk1.4.2
    -windows 2000 professional 5.00.2195 service pack 3
    -pentium III 870 Mhz
    -x86-based PC
    -RAM 256 Mhz
    Anyone knows why, plz help me with this puzzle

    Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
    A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

  • How to get comparable Oracle JDBC performance using Java 1.4 vs 1.1.7?

    Our application makes extensive use of JDBC to access an Oracle database. We wrote it a number of years ago using java 1.1.7 and we have been unable to move to new versions of java because of the performance degradation.
    I traced the problem to JDBC calls. I can reproduce the problem using a simple program that simply connects to the database, executes a simple query and then reads the data. The same program running under java 1.4 is about 60% slower than under java 1.1.7. The query is about 80% slower and getting the data is about 150% slower!
    The program is attached below. Note, I run the steps twice as the first time the times are much larger which I attribute to java doing some initializations. So the second set of values I think are more representative of the actual performance in our application where there are numerous accesses to the database. Specifically, I focus on step 4 which is the execute query command and step 5 which is the data retrieval step. The table being read has 4 columns with 170 tuples in it.
    Here are the timings I get when I run this on a Sparc Ultra 5 running
    SunOs 5.8 using an Oracle database running 8.1.7:
                     java 1.1.7  java 1.4
            overall:    2.1s         3.5s
            step 1:     30           200
            step 2:    886          2009
            step 3:      2             2
            step 4:      9            17
            step 5:    122           187
            step 6:      1             1
            step 1:      0             0
            step 2:    203           161
            step 3:      0             1
            step 4:      8            15   <-   87% slower
            step 5:     48           117   <-  143% slower
            step 6:      1             2I find the same poor performance from java versions 1.2 and 1.3.
    I tried using DataDirect's type 4 JDBC driver which gives a little better performance but overall it is still much slower than using java 1.1.7.
    Why do the newer versions of java have such poor performance when using JDBC?
    What can be done so that we can have performance similar to java 1.1.7
    using java 1.4?

    }

    If I run my sample program with the -server option, it
    takes a lot longer (6.8s vs 3.5s).Which has to be expected, as the -server option optimizes for long running programs - so it shoudl go with my second suggestion, more below...
    I am not certain what you mean by "just let the jvm
    running". Our users issue a command (in Unix) which
    invokes one of our java programs to access or update
    data in a database. I think what you are suggesting
    would require that I rewrite our application to have a
    java program always running on the users workstation
    and to also rewrite our
    commands (over a hundred) to some how pass data and
    receive data with this new server java program. That
    does not seem a very reasonable just to move to a new
    version of java. Or are you suggesting something
    else?No I was just suggestion what you descript. But if this is not an option, then maybe you should merge your java-programs to C or another native language. Or you could try the IBM-JDK with the -faststart (or similar) option. If thew Unix you mention is AIX, then there would be the option of a resetable-vm. But I cannot say if this VM would solve your problem. Java is definitly not good for applications which only issue some unqiue commands because the hotspot-compiler can not be efficiently used there. You can only try to get 1.1.7 performance by experimenting with vm-parameters (execute java -X).
