JDBC issue when accessing an Entity Bean

Hi,
WLCS 3.1
WLS 5.1 sp6
Windows NT
Oracle 8.1.6
I am having problems with an Entity bean, I have originaly deployed and had it
running on cloudscape. I decided I need to deploy it to Oracle 8.1.6, on startup
of WLCS the bean was deployed to the connection pool correctly using Weblogic
JDriver.
The bit I cannot understand is when I try and do a FindByPrimaryKey on the Entity
Bean the following exception is thrown by oracle, which leads me to believe this
must be an Oracle/Jdbc problem.
Here you can see that the bean has been deployed on a valid connection pool.

ran my client which tried to invoke this bean with the above exception.

Hi Wayne,
I'd recommend you installing of latest SP for WL plus installing of Oracle
8.1.7 thing driver.

  • Issue when accessing standard LM transactions via ITS

    Hi,
    We are implementing WM using ITS Mobile.
    We have developed certain custom screens and also used standard transactions such as LM02 and LM04.We have created  a internet service for transaction LM01 and published all our custom and standard screens within the service.
    When testing the transactions in R/3 using LM01 transaction..there were no issue...
    But when testing the same in ITS....once we enter into a standard transaction like LM02(By clicking the corresponding menu entry) and click on Back button...it must bring me back to my menu( transaction LM01)...instead...my ITS session gets logged off...displaying message...'You have been logged off from SAP NetWeaver Application Server'.
    We are facing the same issue when we try to access standard LM transactions via ITS...
    I tried to analyze by debugging from ITS....but the flow of R/3 and ITS remains the same...
    These are my service parameters..
    ~THEME     99
    ~SINGLETRANSACTION     1
    ~ITSMOBILE     1
    ~TRANSACTION          LM01
    ~SOURCES     ZWM_MENU,itsmobile
    ~GENERATEDYNPRO     1

    Did any of you face a similar kind of issue when accessing standard LM transactions in ITS ?
    Kindly Suggest.
    Regards,
    Thyagu.

    Hello,
    I am also trying to implement WM using ISTMobile, but i have a little problem... when i am in my local network the service works and calls the page in the browser, but when i am in other network it gives me "Could not connect to remote server" (off course).
    I undertand that i can´t access my server through other networks...  but can anyone tell me if i it is possible to access SAP ITSMobile transactions through the internet?? Is the solution create a VPN network to my local network or something like that?
    Thanks a lot.

  • How to use same transaction when calling CMP entity beans and  DAO (JDBC)

    We are currently using Weblogic 8.1 SP2 with an Oracle 10g database (using XA thin and non-XA drivers).
    We have a session bean that invokes an entity bean and a DAO (data access object pattern) in order to add data in 2 separate tables (account and history). Rows are added to the first (account) table using a CMP Entity bean while inserts are done in the 2nd (history) table using a DAO. Here is some pseudo code:
    addHistorySessionBean (trans-attribute="Required")
    begin
    Step #1 - call addAccountEntityBean (trans- attribute="Required")
    Step #2 - call addHistoryDAO (get datasource, connection)
    end
    The 2nd table (history) has a foreign key constraint to ensure that the corresponding key exists in the first (account) table. Unfortunately, DAO inserts on the 2nd (history) table fail with a foreign key constraint violation (INTEGRITY CONSTRAINT VIOLATION - PARENT KEY NOT FOUND!) since they cannot see the row added to the 1st (account) table in step #1 by the CMP entity bean.
    How does one ensure that all this is done in a single transaction ? It appears that the app server creates two seperate transactions (one for the session bean facade and the entity bean and a 2nd transaction (when we retrieve a connection using the same data source JNDI name) for the DAO.
    A post on server side suggested using a "<resource-ref>" in the session bean to tie the two potentially separate transactions together, but that does not work for us. However, I am not sure if we are doing that correctly. After we define the resource ref in the session facade bean, do we use the resource ref "name" attribute to lookup the datasource or do we still lookup the datasource by JNDI name ? Do we need to define the resource-ref tag in the entity bean also ?
    Does Weblogic allow using a single transaction for this type of a scenario ? How does one specify within Weblogic that the same transaction should be utilized by the entity bean and any subsequent DAOs?
    People have also suggested that we defer constraint checking until the transaction(s) are committed but that sounds like a work acount without addressing this issue. Would postponing the constraint checking in Oracle cause any additional overhead ?
    Any suggestions with specific examples or documentation on how to address this issue will be gratefully appreciated.

    Thanks for your suggestion. Unfortunately, this does not work since it appears that there are 2 separate transactions going on here. One, the original one initiated by the session bean and used by the entity bean and the other initiated by the DAO. Any other ideas appreciated.
    Hi,
    Try setting the delay-database-inserts tag to
    ejbCreate in RDBMS descriptor file.

  • Client Program accessing J2EE entity Bean

    I have trouble find my Course J2EE bean from a client. (The client
    runs on the same computer but a different VM from the bean.)
    In Glassfish (Sun Application Server Nine), I set up a simple
    Container-Managed Entity Bean. I tried to access it from an external
    client as described in the glassfish EJB
    FAQ https://glassfish.dev.java.net/javaee5/ejb/EJB-FAQ.html
    Here is the client program:

    }Here is the error message:

    in the forum started "Error When running the Client Program" by sree_devi,
    I checked
    the following. I went to "Jndi Tree Browsing" from the Administrative Console
    and I found a "RS.CourseHome" entry under "ejb" I found RS.CourseHome there
    but did not see the "Course" tghat I expected to see
    Thus, I tried the version above:
    package RS;
       --- imports deleted for conciseness
    import Debug.*;
    public class Client {

    catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
    catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
    }When I run it, I get the following Naming Exception: Course not found
    I confirmed at the administrative console, that I have "Course" listed
    under Enterprise Applications:
    As per the ejb FAQ, I set up my $CLASSPATH so it starts as follows:

    /opt/j2ee/SUNWappserver/lib/javaee.jar:I also verifed in my domain.xml that the orb-listener-1, the default

    hi s-mcgowan,
    "some other processing" comprises of printing of debug lines and publishing to the message queue using JMS. I added more debug lines so that i could see whats really happening... here is the result
    myTableHome.create(...); <----------- no exception was thrown and it returned LocalMyTable object
    print out "Insert successful"
    print out "publishing message"
    ... publish message to message queue using JMS...
    print out "Publish done"
    ... after few milliseconds...
    java.sql.BatchUpdateException: Data exception -- row already exist in index PK_MYTABLE on table MYTABLE.
    From the exception it seems like its doing a batch insert. So that seems to explain why the java.sql.BatchUpdateException is thrown few milliseconds after my call to myTableHome.create(...);
    Is it possible to disable batch update / insert? how?
    thanks in advance,
    leigh

    Hi,
    This seems to be the Hello world EJB application with a small
    modification(probably an addition of test directory or a java file). I would
    recomend you to go through every line of the document on deploying this
    application. There is another posting regarding the same issue in this forum.

  • Database access using Entity Beans

    How does it work? In the examples I've seen, there is no SQL statement
    being generated, and I no code establishing the JDBC bridge...
    What am I missing? How do I look up a record in a database using an
    entity bean?
    Thanks!!!
    -Dan

    The Entity Bean remote interface methods access the database.
    InitialContext ic=new InitialContext();
    EntityBHome eh = (EntityBHome)ic.lookup("com.ejb.EntityBHome");
    EntityB entityB=eh.findByPrimaryKey(primarykey pk);

  • Ejbc outofmemory error in weblogic 8.1 sp2 when compiling cmp entity beans

    I have a set of entity beans which compiled [ejbc step]fine under weblogic7.0 sp4. But when i try to to the same thing under weblogic 8.1 i get an outofmemory error. Any pointers

    I am using 81 sp4

  • Recurring CacheFullException when creating new Entity Bean

    Normally I can create new instances of my Entity Bean just fine. However, at some point (whether it's after a rollback or not, I don't yet know), I get a CacheFullException when trying to create a new Entity Bean.
    The CacheFullException exception shows a size that increments by one each time this error occurs. The reported size in the exception continually increases way past the max-beans-in-cache amount of 1000. Yet, the Administrator console reports the "Cached beans current count" as zero. So, the cache appears empty, yet every attempt to create a new entity bean fails with a CacheFullException!
    I am using Weblogic Server 8.1 SP3, database concurrency strategy, BMP, and Oracle 9i. The Entity Bean's primary key class was generated by EJBGen (primary key is a java long).
    Stopping and restarting the Weblogic server fixes the problem temporarily.
    Any help would be greatly appreciated.
    Jim

    Yes, but if objects are equal they should have same
    hashCode. If it is not happening, you have a problem.Yes, and equal objects do have the same hash code. Please see below for primary key class implementation as generated by EJBGen 2.16.
    There can be a bug in reporting number of beans.OK, are you saying there is a bug that sometimes shows 0 beans in the cache when the cache is actually full? And even if the cache were full, all the beans would have to be involved in transactions for there not to be room for one more new bean in the cache. And I know that there are no other transactions going on, because this is an isolated system that only I am using. Again, Weblogic Server 8.1 SP3.
    It is possible if your PKs don't implement
    equals/hashCode correctly.They look correct to me. Here is the primary key class implementation as generated by EJBGen 2.16. The primary key is a java long, and I am using CMP (not BMP as I mistakenly reported earlier).
    public class StatusPK implements Serializable {
    public long statusID;
    public StatusPK() {}
    public StatusPK(long statusID) {
    this.statusID = statusID;
    private int m_hashCode = 0;
    public int hashCode() {
    if(0==m_hashCode) {
    m_hashCode = ((int) statusID);
    return m_hashCode;
    public boolean equals(Object other) {
    if(other==this) return true;
    if(null==other) return false;
    if(other.hashCode() != hashCode()) return false;
    try {
    StatusPK other2 = (StatusPK) other;
    return (this.statusID==other2.statusID)
    catch(ClassCastException ex) {
    return false;
    The only problem I see with this class is if the default constructor (no args) would be called, then the primary key and hashCode would always be zero. However, I'm assuming here that EJBGen knows what it is doing and that the default constructor is never actually used. In addition, I know that all of the beans in the database have valid primary keys, and they were created the same way that eventually continually fails later on.
    Thanks...

  • Issue when inserting Child Entity (Notes) with Contact

    Hi,
    I am getting the following error message when inserting Contacts with a child entity i.e. Notes which is quite misleading
    SOAP fault from Item: OnDemandServicesObjMgr_eng_44477.log(SBL-DAT-00542)Method 'SetFieldValue' of business component 'Contact Note' (integration component 'Contact_Contact Note') returned the following error: "Access denied.(SBL-DAT-00542)"(SBL-EAI-04376
    As suggested in earlier post I have tried providing values for fields NotesID and ContactID as well and even though it gives this error message.
    Thanks
    Arif

    Hi, From the error message it looks like the access profile settings for the WS user doesn't have required privileges to create a note for contact. You make have to check access profile settings first and then try it

    In an application we receive sign and verify files(ordinary information files) as seperate processes. When signing files we do a check on the CRL of the signing certificate. Below are the steps in which the check is done:
    1- Receive a file. Get its signing certificate from a repository.
    2-save/cache the CRL file in a directory(we do check if the file already exists when creating). We have configured a time out period with which the CRL will be updated in case of modifications.
    File file = new File(cacheDirSystem.getProperty("file.separator")+crlUrl(url));+
    fs = new FileOutputStream(file);
    X509CRL crl.writeTo(fs);
    3-Get the CRL Distribution Point from the signing certificate and load the file that was saved to check with the Certificate Revocation Lists.
    String as[] = getDistributionPointNameURIs((GeneralNames)dpName);
    File file = new File(cacheDirSystem.getProperty("file.separator")+modifyUrl(as));+
    lastModified=file.lastModified();
    fstream = new FileInputStream(file);
    crlObject.crl=new X509CRL(fstream);
    When running signing processes with more than 150 files(the file size can go upto 2MB) over a period of time, the CRL is sometimes not found and InvalidCRLException is thrown. I think its some problem with accessing the CRL file concurrently since it could also be updated at some point.
    Im trying to figure out if a file lock or some other way would help to reslove this. I need help/suggestions on this.
    Thanks in advance

    I think its some problem with accessing the CRL file concurrentlyUndoubtedly. You should write the new data to a new file and do a delete/rename operation. All clients should cope with not finding the CRL file by retrying a couple of times in case they tried between the delete and the rename.
    This is a file handling question, or concurrency question, not really a security question.

  • Authentification issue when accessing by web

    hi,
    i am trying to publish by planning folder on BSP interface
    after having generated the pages, i tried to see my page and i get the following message : "please activate single sign on service"
    could someone tell me hot to activate this service ?
    thanks,

    Hi,
    Activate Single Sign On (SSO) with the following profile parameters: (On (SSO) with following profile parameters necessary)
    - login/accept_sso2_ticket=1
    - login/create_sso2_ticket=1 or 2
    - icm/server_port_...=PROT=HTTPS ...
    To change these profile parameters, you need to reboot the server.
    Also refer OSS note 817529 and check out the link https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sapportals.km.docs/documents/a1-8-4/sso overview.pdf

  • Problems accessing fields in a CMP entity bean from a session bean

    Hello everybody,
    I'm getting the next problem: when I try to access a field in a CMP entity bean that I have instantiated from a session bean (trhoug entitybean.getNameOfField), I get the error "the entity bean does not exist in the database".
    This entity bean is accessing a table in an external database (not the DB of the WAS), but I know that it's getting the correct data from the table, since  I check the entitybean.size() and the entitybean.findByPrimaryKey(), and I get the right information. For some reason, the only thing that it doesn't work in the entity bean are the getter/setter methods (I created them automatically after having created the entity fields).
    I access the entity bean through its local interface...
    I know it's really difficult to give an answer with so few details, but... does anybody think I forgot something important to configure??
    Thank very much in advance!!
    Isidro

    getter and setter methods for cmp-fields are abstract.
    getter and setter methods for cmr-fields are abstract.

    Hi:
    Which method in a CMP Entity bean should be abstract? just only SetXXX
    and
    GetXXX?
    Thanks!

  • How to specify JDBC Oracle url using deployment tool - Entity Bean

    Hello I'am new to EJB.
    When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
    and password to establish a connection object, how does one specify that in the deployment
    tool?
    Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
    private String dbName = "java:comp/env/jdbc/AccountDB";
    private void makeConnection() throws NamingException, SQLException {
    InitialContext ic = new InitialContext();
    DataSource ds = (DataSource) ic.lookup(dbName);
    con = ds.getConnection();
    Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
    ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
    what would my dbName be at the top?
    Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
    In the Resource Factories Reference Code I've add a reference of
    Coded Name: jdbc/dev
    Type: javax.sql.DataSource
    Authentication: Container
    and down the bottom of the I've put JNDI Name: MyAccount
    according to the AccountClient code of:
    Context initial = new InitialContext();
    Object objref = initial.lookup("MyAccount");
    and put User Name of "system" and Password of "manager"
    I'am sure in the source code I have to put
    Class.forName("oracle.jdbc.driver.OracleDriver")
    else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
    What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
    Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
    Please help
    Thanks
    Abraham Khalil

    When running the client after successful deployment with jdbc, I'am getting

    One thing I don't like about EJB is that everything is transparent which is good! But its much
    harder to debug! :( Tried to see if I can figure it out. Hope someone has seen this problem before?

  • Problems accessing tables in oracle database with ejb entity bean

    I have created a simple server application that uses an entity bean (version 2.0) for an existing table in oracle database, and a session bean that is used as an outside interface for performing operations on that table.
    after deploying the server and client application the client attempts to perform an operation with the session bean remote interface it obtained.
    The session bean uses a locale interface to communicate with the entity bean, but when it tries to use its methods (create, findByXXX) it always get the following Exception: java.sql.SQLException: ORA-00942: table or view does not exist.
    the table of course exists, and the username password I'm using has all the permissions needed for this table.
    note - I'm using the Forte enterprise edition 4.0 as developer tool.
    I'll be glad to get some help.
    Here is the full stack trace of the exception:

    Well it seems like the problems has a simple explanation. The Forte assigns a default table name (<entityName>EJBTable) when creating an entity bean from an existsing table in DB (which is not the same as the one it was created from !!!). Also, for reason unknown, when you deploy these entity beans, it doesn't even create the new table under its new name (even if instructed to).
    So using the Forte we managed to use successfuly only entity beans that were created "from scretch" (when deployed their tables are created).
    Does anyone know how to change the default name the Forte uses, and make it work properly with entity beans created from an existsing table (without going over the xml's) ?

  • Problems accessing ejb 3.0 entity bean from project

    I have written some code using ejb 3.0 and was previously accessing the entity bean without problem when both ejbs and the accessing code were in the same project. However I have moved the accessing code into a different project within the same application and now when the code tries to accessing the entity bean I get the following error:

    Now, of course I could move the code back into the same project, but as I understand it that is just the point of ejbs. I'm looking up the entity bean thus:
    final Context context = InitialContext();
    ingestionSessionEJB =
    (IngestionSessionEJB)context.lookup("IngestionSessionEJB");
    It may be true that I don't understand the way lookup works, but to be honest I can't find the docs that explain what I've got wrong.
    Please help.

    hi
    Double Click on the project which is goin to use the project which contains bean from the Application Navigator window. The project properties window will open. Choose the "Dependencies" item from left panel. click on the radio "User Project Settings" and select another project which contain ejb which you're goin to access...
    Best Of Luck
