Problem in submitting data while refresh in web application

Hi all,
I have problem in submitting data while refreshing the page.
In my application voucher number is generated automatically and as soon as number is genereated voucher detail is inserted in database for newly generated voucher number.
Both of these activity done on the same page as my client want so.
Now I have problem that while refreshing the page, the same data for incremented voucher number stored in database that should not be done.
If there is any solution for this situation other than 1) Generating number in one page and inserting on another 2) block refresh activity, then please reply me.
It's urgent. Your help will help me a lot.
regards,
Deepalee

  • A web developer problem while running a web application

    Hi all,
    I'm novice to J2EE.
    I've encountered a problem while accessing the deployed module in weblogic 8.1 server.
    I'm sure that the webapplication module is deployed as i saw my module in administration console & also the status said that it is deployed.
    when i access my web application by specifying the proper server and port no and context root it is showing
    either 505 - resource not found error(http://localhost:7001/Suresh-2/Suresh) or 404 - not found error.( http://localhost:7001/Suresh-2/Suresh)
    Now let me elaborate what i've done till now.
    My webapplication folder structure is : C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\classes\Sai\ServExamp.class
    My servlet is ServExamp.java
    I created a folder called "Suresh". In that folder created another folder called "WEB-INF". In WEB-INF created a folder called "Classes".
    Since my servlet is in package "Sai", the .class file reside in \Suresh\WEB-INF\Classes\Sai\ServExamp.class
    The source code is :
    package Sai;
    import javax.servlet.*;
    import javax.servlet.http.*;
    import java.io.*;
    public class ServExamp extends HttpServlet
    public void doPost(HttpServletRequest req,HttpServletResponse res)throws IOException
    PrintWriter out=res.getWriter();
    java.util.Date today=new java.util.Date();
    out.println("<html>"+"<body>"+
    "<h1 align=center>HF\'s Chapter1 Servlet </h1>"
    +"<br>"+today+"</body>"+"</html>");
    Now i'm almost done creating a web application. Next, I constructed a simple web.xml descriptor that gives a web friendly name for my servlet, and points to the servlet. I constructed web.xml descriptor file in the WEB-INF folder (C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\).
    The web.xml file source is :
    <!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">
    <web-app>
    <display-name>Hello World Web Application</display-name>
    <description>Test Servlet</description>
    <servlet>
    <servlet-name>ServExamp</servlet-name>
    <servlet-class>Sai.ServExamp</servlet-class>
    </servlet>
    <servlet-mapping>
    <servlet-name>ServExamp</servlet-name>
    <url-pattern>/Suresh</url-pattern>
    </servlet-mapping>
    </web-app>
    Now I have told Weblogic that the URI /Suresh corresponds to my servlet "Sai.ServExamp".
    My Web Application is ready to be deployed at this point. I logged onto Weblogic's admin console,
    1) clicked on deployments, then navigated to "Web Application Modules" .
    2) Clicked "Deploy new Web Application Module"
    3) Navigated to the location of your web application folder (Suresh). There was a radio button next to it indicating that I can select that folder as a valid web application.
    4) I Clicked that radio button and clicked "Target Module".
    5) It informed that my web application "Suresh" will be deployed to myServer.It asked a name for my web application deployment. By default it was "Suresh"
    I clicked Deploy.
    6) After deployment, my web application "Suresh" appeared in the "Web Application Modules" tree on the left.
    I Clicked on "Suresh"( my web application) then clicked the testing tab, then clicked the link shown there(http://localhost:7001/Suresh-2).
    It was not showing my servlet (showed a 403 error)
    Error - 403
    This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
    I think so it came b'coz I don't have an index.html or index.jsp page.
    7)Instead,I added my servlet on to the URL it provided.
    http://localhost:7001/Suresh-2/Suresh
    It is showing these error code: Http: 505 resource not allowed
    The page cannot be displayed
    The page you are looking for cannot be displayed because the address is incorrect.
    Please try the following:
    If you typed the page address in the Address bar, check that it is entered correctly.
    Open the localhost:7001 home page and then look for links to the information you want.
    Click Search to look for information on the Internet.
    when i just type : http://localhost:7001/ -> Error 404 not found error
    it's showing
    Error 404--Not Found
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
    10.4.5 404 Not Found
    The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
    If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
    I want to run my web application & any help would be appreciated.
    Thanks in advance.
    with regards,
    S.SayeeNarayanan.
    Note: I even deployed my war file, which i got by execution of (jar cv0f webapp.war . ) command from the root directory of my web application i.e. Suresh
    Then executed my webapplication it is showing
    error-505 resource not allowed.

  • Getting and MDX Error while refreshing a WEBI Report

    Hi,
    I have a problem in developing/refreshing my Webi Info view report.
    I have my report like this.
    It has 15 dimensions and 3 measures.
    Purpose of the report is to display the purchase order details for a particular state/or all in a Country for a particular year.
    In this scenario my database has two Calendar Years: 2011 and 2012.
    And states (in US) as New York, Rhone Island etc..
    Here comes the typical issue.
    I have developed the report and when i m trying to refresh the report giving 2011 as Year and New York as State for prompts and generating the report.
    Now i m getting the error of MDX query; Below is the error message:
    "Database error: The MDX query SELECT  {  (Measures).[35LYTRYAVWK4BUTF5WL7PC9AR] }  ON COLUMNS , NON EMPTY UNORDER( FILTER( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN(  {  (0PLANT__0REGION).[US NY] } ,  {  (ZIPO_ID__ZCALYEAR).[2011] }  ),  (0PLANT).[LEVEL01].MEMBERS ),  (ZIPO_ID).[LEVEL01].MEMBERS ),  (0PUR_GROUP).[LEVEL01].MEMBERS ),  (ZIVENDOR).[LEVEL01].MEMBERS ),  {  (ZIPO_ID__ZIPRICING).[TIME & MATERIAL] }  ),  {  (ZIPO_ID__ZISEGMNT).[ELECTRIC],  (ZIPO_ID__ZISEGMNT).[GAS & ELECTRIC],  (ZIPO_ID__ZISEGMNT).[GAS] }  ), EXCEPT(  {  (ZIPO_ID__ZICLASS).[LEVEL01].MEMBERS } , {  {  (ZIPO_ID__ZICLASS).[STOCK] }  } ) ),  (0CONTRSTART).[LEVEL01].MEMBERS ),  (0CONTREND).[LEVEL01].MEMBERS ),  (ZIPO_ID__0ENTRY_DATE).[LEVEL01].MEMBERS ),  (ZIPO_ID__ZIPOAPDAT).[LEVEL01].MEMBERS ),   (Measures).[35LYTRYAVWK4BUTF5WL7PC9AR] > 100000) )  DIMENSION PROPERTIES MEMBER_NAME, MEMBER_CAPTION,  (0CONTREND).[20CONTREND],  (0CONTRSTART).[20CONTRSTART],  (ZIPO_ID).[2ZIPO_ID],  (ZIPO_ID__ZIPRICING).[1ZIPO_ID__ZIPRICING],  (ZIPO_ID__ZIPRICING).[2ZIPO_ID__ZIPRICING],  (ZIVENDOR).[20NAME],  (ZIVENDOR).[2ZIVENDOR] ON ROWS FROM  (ZSC_MPDTD/ZSC_MPDTD_QU0099)  failed to execute with the error Please enter a valid value for characteristic 0PLANT__0REGION.. (IES 10901) (WIS 10901)"
    This error is coming only when i m selecting 2011 and New York as prompt values.
    When i m selecting any other value combinations, i dont get any error.
    I m not sure why this error is coming.
    Actually to say there is no data for the combination 2011 and New York. So ideally it has to display "No Data to Retrieve".
    But this is not the case with these conditions.
    Please suggset.
    Thanks,
    Prasad.

    check the statement in transactions MDXTEST,
    check [US NY] in 0REGION as the stament is using (0PLANT__0REGION).[US NY]

  • Getting error while refreshing the Webi report

    Hi Guys,
    I am getting error, while refreshing Webi reports. Error like:
    A database error occured. The database error text is: Error in MDDataSetBW.GetCellData. Time limit exceeded.. (WIS 10901)
    Could anyone please reply.
    Regards,

    Hi,
    If it's not the universe limits, then I think you've hit the "MDX result contains too many cells" (more than 1million) problem.
    So, I suspect a long running query, no filters/variable restrictions, and You've probably got a dump in ST22.
    I don't know what BW you have, but if it is BW 7, do you have Enhancement Pack 01 and SP05<->10  ?
    You should check out all the latest corrections from component BW-BEX-OT-MDX
    the final proof of the pudding would be to enable MDA / SOFA log , capture the MDX SELECT statement and test it in BW MDXTEST - i bet you get the same error there.

  • Error (IES10901) (WIS 10901) while refreshing the Webi report

    Hi Gurus,
    We have created webi reports using Universe design tool on top of BEX Query based on 0SD_C03 cube and now we are facing Database error: A runtime exception has occured. (Error loading cube 0sd_c03 (catalog : % 3).

    When I run the the query in rsrt its working absolutely fine.
    Note that we are using BOBJ 4.0 SP7 and this issue has come recently.
    Any idea or help on this would be appreciated.
    Regards,

    Hello Monali,
    are you getting this error constantly or sometimes?
    what type of connection are you using for your Webi report
    Is it Specified user name/password OLAP connection or SSO Olap connection
    If your are using Specified user name/password OLAP then try with SSO connection because SAp recommendation is not to use  Specified user name/password OLAP connections..to resolve this kind of issues please restart DSL bridge..

    Hi all,
    I created WebI report based on universe that is connected to Excel data. Through DSN I m accesing Excel Data . I created same DSN in server also. If I refresh the webI Report in BO server it tells the following error.

  • Design considerations while accessing data of a different web application

    I am database developer for a web application (*WebApp1*) which supports around *6 million* merchant data across various tables in database (*DB1*).
    The users for the above mentioned application are less, around *50* who monitor the 6 million merchant data.
    Now a proposal has come up to develop a second web application for the merchants themselves.
    Thus the user base for this web application (*WebApp2*) is in millions.
    Now the requirement for WebApp2 is :
    On each login of individual merchants, they need to see their individual data (mostly read-only) which is stored in (*DB1*)
    along with other data which is stored in its own database (*DB2*). WebApp2 will have other functionalities too but those
    are independent of WebApp1.
    Now I can think of three approaches how to display DB1 data in WebApp2 :
    1. Creating a stored procedure and accessing DB1 data through dblink. (*Cons* - have seen access through dblink is slower as it serializes access).
    2. Replicate DB1 data to DB2 through batch jobs running every night. (*Cons* - Will store the same data in 2 places and will have the headache of data sync.)
    3. WebApp1 will expose webservice using DB2 data, so that on each login, WebApp2 users use the webservice to display DB1 data through webservice.
    (Please answer if there are any cons. beacuse of high user base ?)
    Need your suggestion and views. Also if there are any other way please let me know.
    Will it depend on any other factor ? Let me know if you need any further information.
    Cheers !!!

    Ah - this is a much bigger question! And may be outside the scope of this forum to answer. I will have a go though.
    The question really isn't can the database support 6,000,000 users. It is how many of the users will be making database requests at the same time, what is the average elapsed time of each request, and what do your users regard as an acceptable response time to each request?
    To use a (very) simple analogy, my company employs 30,000 people but the IT Service Desk that they call if they have a problem with their PC is only staffed by 30 people. This is because the Service Desk Manager has estimated that at any one time only 1% of all employees will need to call the Service Desk. On average each call takes 6 minutes to resolve and the response time agreed with the business to a call is 1 hour. So within an hour one Service Desk technician can answer 10 calls in an hour, so 30 technician can answer 300 calls an hour.
    Now you can apply this analogy to a computer system. The scalability of database systems is generally limited by the amount of available CPU. If we determine that the average database call uses 10ms of CPU, and the user will accept a response time of 1s, then each CPU can service 100 database calls within that response time. Multiply that by the number of available CPUs and you have a (very rough) idea of how far the database will scale. An server with 8 cores could support 800 concurrent requests. A cluster with 4 servers each with 8 cores could support 3200 concurrent requests.
    I would stress that this is very crude. Much more information would be required to determine what the limits of database scalability were. My example does not take account of other source of potential latency, such as the network or the storage subsystem if requests involve significant physical I/O. Or indeed the latency in the application itself.
    So, you need to answer these questions:
    - How many concurrent database requests need to be supported
    - What is the average amount of database CPU that each database request will consume
    - What is the maximum acceptable elapsed time for each database request
    On a more practical note, your application must use some form of connection pooling to limit the number of database connections required to service all the required database activity. You can scale the database horizontally using RAC and in extreme cases you can offload read activity entirely from the database using a middle-tier caching solution such a Coherence, GigaSpaces or GemFire.
    That's probably enough for now. Any more and you'll probably need to get some consultancy!

    Does anyone knows this ..

    In your deploy message it says that it can't initialize your servlet because it is missing a java class from the logging framework that is used by hibernate. It might also be possible that that logging framework ([SL4J|http://www.slf4j.org/]) is configured to use a logger that is not available in your Netweaver 7.3 installation. Maybe check the documentation of sl4j for details. There is also a [document|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/bf0d57db-0c01-0010-6fa3-83503981eed4] about Hibernate on Netweaver but that was back when Hibernate did not use sl4j. Probably you just need to add the sl4j library to your libs.

    By defining this element, means that every manager will be changed.
    So when running a cluster, only make sure that you have webapps in there
    that need to be clustered and remove the other ones.
    A cluster has the following parameters:
    className = the fully qualified name of the cluster class
    name = a descriptive name for your cluster, can be anything
    mcastAddr = the multicast address, has to be the same for all the nodes
    mcastPort = the multicast port, has to be the same for all the nodes
    mcastBindAddr = bind the multicast socket to a specific address
    mcastTTL = the multicast TTL if you want to limit your broadcast
    mcastSoTimeout = the multicast readtimeout
    mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
    mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
    tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
    tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
    in case of multiple ethernet cards.
    auto means that address becomes
    InetAddress.getLocalHost().getHostAddress()
    tcpListenPort = the tcp listen port
    tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
    has a wakup bug in java.nio. Set to 0 for no timeout
    printToScreen = true means that managers will also print to std.out
    expireSessionsOnShutdown = true means that
    useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
    false means to replicate the session after each request.
    false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
    <%
    HashMap map = (HashMap)session.getAttribute("map");
    map.put("key","value");
    %>
    replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
    * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
    * Synchronous means that the thread that executes the request, is also the
    thread the replicates the data to the other nodes, and will not return until all
    nodes have received the information.
    * Asynchronous means that there is a specific 'sender' thread for each cluster node,
    so the request thread will queue the replication request into a "smart" queue,
    and then return to the client.
    The "smart" queue is a queue where when a session is added to the queue, and the same session
    already exists in the queue from a previous request, that session will be replaced
    in the queue instead of replicating two requests. This almost never happens, unless there is a
    large network delay.
    -->
    <!--
    When configuring for clustering, you also add in a valve to catch all the requests
    coming in, at the end of the request, the session may or may not be replicated.
    A session is replicated if and only if all the conditions are met:
    1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
    2. a session exists (has been created)
    3. the request is not trapped by the "filter" attribute
    The filter attribute is to filter out requests that could not modify the session,
    hence we don't replicate the session after the end of this request.
    The filter is negative, ie, anything you put in the filter, you mean to filter out,
    ie, no replication will be done on requests that match one of the filters.
    The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
    filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
    ending with .gif and .js are intercepted.
    The deployer element can be used to deploy apps cluster wide.
    Currently the deployment only deploys/undeploys to working members in the cluster
    so no WARs are copied upons startup of a broken node.
    The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
    When a new war file is added the war gets deployed to the local instance,
    and then deployed to the other instances in the cluster.
    When a war file is deleted from the watchDir the war is undeployed locally
    and cluster wide

    I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
    My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
    in a browser. Here I accept a username and password from the user and then do the validation in
    a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
    accordingly. However when I enter the username and password and click Go in the homepage, nothing is
    displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
    WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
    WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
    IS IT POSSIBLE?WHY WILL THIS HAPPEN?
    I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
    Is there any other thing that I need to set in classpath? Should I have my project as a
    WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?

    I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
    to connect to the database. I have placed my project folder called
    tdm under the webapps folder in Tomcat. This 'tdm' folder consists of
    a collection of html pages,jsp pages and images of my project. Also I created a
    WEB-INF folderand in that I have lib folder which contains catalina-root.jar
    , classes12.jar and nls_charset.jar files. And also in the WEB-INF folder I have the web.xml
    file which looks like this

    mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
    mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
    tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
    tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
    in case of multiple ethernet cards.
    auto means that address becomes
    InetAddress.getLocalHost().getHostAddress()
    tcpListenPort = the tcp listen port
    tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
    has a wakup bug in java.nio. Set to 0 for no timeout
    printToScreen = true means that managers will also print to std.out
    expireSessionsOnShutdown = true means that
    useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
    false means to replicate the session after each request.
    false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
    <%
    HashMap map = (HashMap)session.getAttribute("map");
    map.put("key","value");
    %>
    replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
    * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
    * Synchronous means that the thread that executes the request, is also the
    thread the replicates the data to the other nodes, and will not return until all
    nodes have received the information.
    * Asynchronous means that there is a specific 'sender' thread for each cluster node,
    so the request thread will queue the replication request into a "smart" queue,
    and then return to the client.
    The "smart" queue is a queue where when a session is added to the queue, and the same session
    already exists in the queue from a previous request, that session will be replaced
    in the queue instead of replicating two requests. This almost never happens, unless there is a
    large network delay.
    -->
    <!--
    When configuring for clustering, you also add in a valve to catch all the requests
    coming in, at the end of the request, the session may or may not be replicated.
    A session is replicated if and only if all the conditions are met:
    1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
    2. a session exists (has been created)
    3. the request is not trapped by the "filter" attribute
    The filter attribute is to filter out requests that could not modify the session,
    hence we don't replicate the session after the end of this request.
    The filter is negative, ie, anything you put in the filter, you mean to filter out,
    ie, no replication will be done on requests that match one of the filters.
    The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
    filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
    ending with .gif and .js are intercepted.
    The deployer element can be used to deploy apps cluster wide.
    Currently the deployment only deploys/undeploys to working members in the cluster
    so no WARs are copied upons startup of a broken node.
    The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
    When a new war file is added the war gets deployed to the local instance,
    and then deployed to the other instances in the cluster.
    When a war file is deleted from the watchDir the war is undeployed locally
    and cluster wide

    My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
    in a browser. Here I accept a username and password from the user and then do the validation in
    a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
    accordingly. However when I enter the username and password and click Go in the homepage, nothing is
    displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
    WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
    WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
    IS IT POSSIBLE?WHY WILL THIS HAPPEN?
    I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
    Is there any other thing that I need to set in classpath? Should I have my project as a
    WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?

  • ERRORS WHILE ACCESSING A WEB APPLICATION BASED ON BIBEANS BIB-14657

    My goal was to build a web application based on BIBeans. I developed it in JDeveloper 10g. It was tested on my own computer in the JDeveloper environment
    (Windows XP, PIII 866MHz, RAM 512MB) as well as on my local server (Windows 2000, PIII 1GHz, RAM 1GB) in the JDeveloper and OAS10g environment. Everything worked fine. When I deployed the application on my (let's call it) production server (Windows 2003 Server Enterprise Edition Service Pack 1, 2 x Dual Xenon 3.2GHz, 64-bit, RAM 4GB, L2 1MB) on OAS10g, while accesing the application via
    internet explorer (MS IE, Mozilla Firefox) I got errors (launching the application in JDeveloper failed even sooner as OC4J (embedded) was no able to
    start).
    I would like to mark that on every machine I uset the same version of JDeveloper and the same version of OAS10g.
    Other applications deployed on the OAS10g on the production server operate.
    Unfortunately in application and OAS10g logs there is nothing interesting.
    While deploying I followed instructions from:
    http://www.oracle.com/technology/products/bib/htdocs/904/tech_notes/oc4j/new_oc4j_unix.html
    I get it in my internet explorer:
    javax.servlet.jsp.JspException: BIB-14122: Nie udało się utworzyć podanego obiektu StorageManager.

    I used the same version of BIBeans (bibeans1012.zip - 25 833 300 Bytes) to create BIBeans Catalog in the database as well as to upgrade my JDeveloper where I build my WAR applications. In adition to this, as I mentioned before, my application (the same WAR file, the same database) works fine when deployed on diffrent computer. Besides there is such a difference that my database where is my BIBeans catalog installed resides on the same computer (production machine) where the OAS10g (this one which generates the error BIB-14657). The database and the OAS10g has different ORACLE_HOME.

    Can you please log a TAR with Oracle Support using Metalink to resolve this issue. They can help you collect all the log and trace files to determine the why this problem is occuring.

    Hi there,
    Many thanks for your answer. I am fine but I am sure I will be even more fine
    when I solve this technical issue.
    I checked the weblogic.xml file as you suggested and it is OK.
    I even tried to access the URL "http://www.bea.com/servers/wls610/dtd/weblogic-web-jar.dtd"
    with IE5. I had some doubt regarding our corportate proxy. But it worked fine.
    I can access successfully the dtd with a browser. I really don't see what is going
    wrong. I attached in case of the weblogic.xml file for your examination.

  • Problem in JSF with Swing in a web application

    hi
    i am using jsf for my online projects.my problem is that when i use Swing concept ,the server is closed automatically when i click the swing dialog option 'OK', how can i protect server being closed automatically when user click the the options of Swing dialog box.it is so tedious because my application is going to integrate

    Swing is GUI library for use in desktop applications.
    JSF is a web application framework which runs on an application server and is accessed by clients via web browsers.
    To fully understand what you have done, try accessing your application from a different machine than the server.
    To answer your question, don't invoke System.exit() if you would like the process to continue. But that is the least of your problems.

  • Bobj is undefined error while debugging a web application

    Hello, I am developing an asp.net web application in which I display a report, and testing it by using a sample (dummy) report that's saved on the computer's hard drive.  In design mode, the report displays properly, when when I try to debug the site on my machine (the server in this case, but it should work on any computer, since debugging is done on localhost), the site crashes and returns a Microsoft JScript error 'bobj is undefined'.  I have already tried moving the CrystalReportsViewer folder to be a sub-directory of the application (physical and virtual), as well as adding a script tag to refer to the location of the .js files in that directory, but nothing seems to fix the error.
    I recently tried installing the fix-packs and service packs for crystal reports, but the problem persists.
    I"m running Windows 7, VS 2008, Crystal Reports 2008, and IIS 7.  Thank you in advance.

    Hi;
    Compiling as 32 bit is only available for a Windows based application, not a Web one. You need to configure IIS to run either 32 or 64 bit.
    As for the bobj undefined error, try these kbases:
