It is a bug for the EJB container to respond with an NPE.
(It's been fixed in v9 Beta, and it might be fixed in an 8.1 service pack but I can't recall off the top of my head). At any rate, I'm pretty sure that an EJB QL query with an empty WHERE clause will cause this. I would look for a query that ends in ' WHERE'.

  • Question about weblogic-cmp-rdbms-jar.xml

    WinNT 4.0 SP6, Weblogic 5.10
    In the online documents, it says:
    ---- digest from the online documents ----
    The following example finds all the EJBs in a table. It uses the
    sample finder method signature:
    public Enumeration findAllAccounts()
    throws FinderException, RemoteException
    The sample <finder> stanza uses an empty WLQL string:
    <finder>
    <method-name>findAllAccounts</method-name>
    <finder-query></finder-query>
    </finder>
    ---- End of digest ----
    However I implement it in my sample EJB, call findAllAccounts in the
    client JSP file, get a SQLException about "null after where".
    How can i solve this problem?
    Thanks in advance,

    Are you trying to make an EJB 1.1 CMP bean or an EJB 2.0 CMP bean.
    It looks like you have an EJB 1.1 ejb-jar.xml, but have requested an EJB 2.0 cmp descriptor.
    Take a look at examples/ejb/basic/containerManaged and ejb20/basic/containerManaged for the 2 examples.

  • Why weblogic-cmp-rdbms-jar.xml.old gets created in Weblogic 7?

    Hi all,
    I use the build.bat file for creating the jar file
    build.bat
    ==========
    mkdir build build\META-INF
    copy *.xml build\META-INF
    @REM Compile EJB classes into the build directory (jar preparation)
    javac -d build *.java
    @REM Make a EJB jar file, including XML deployment descriptors
    cd build
    jar cv0f std_ejb_accountcmp.jar META-INF ejb
    cd ..
    @REM Run EJBC on jar file
    java -classpath %WL_HOME%/lib/weblogic.jar weblogic.ejbc -convertDDs -verbose -keepgenerated -compiler javac build\std_ejb_accountcmp.jar d:\ejb_accountcmp.jar
    =============================================================
    Any ideas why when u unjar the jar file created for deployment in Weblogic 7.0, it creates an old copy of the xml files used
    For example :
    weblogic-ejb-jar.xml has weblogic-ejb-jar.xml.old
    ejb-jar.xml has ejb-jar.xml.old
    Why does it replace the weblogic-cmp-rdbms-jar.xml to weblogic-cmp-rdbms-jar.xml.old?
    Rgds,
    Seetesh

    Hi Indra,
    Thanks for ur post.
    I have now renamed the weblogic-cmp-rdbms-jar.xml to weblogic-cmp20-rdbms-jar.xml and made the changes in the weblogic-ejb-jar.xml file in the type-storage parameter.
    Now after executing the foll cmd
    java ..... weblogic.ejbc old.jar new.jar
    The new.jar file contains the generated stub/skeleton along with the additional old files for the 2 xml's ejb-jar.xml and weblogic-ejb-jar.xml.
    Using the Weblogic builder utility, while opening the new.jar file, it discards the old xml deployment descriptors and creates new ones in its place.
    Cld u give me some hints on using the Deployment tool? I use it to deploy the new.jar file.
    Rgds,
    Seetesh

  • Tools for generating weblogic-cmp-rdbms-jar.xml files

    Hi All:
    I am using Weblogic 8.1 sp6 and MyEclipse 5.1.
    Does anybody knows if weblogic 8.1 provides a wizard or tool or some product that will help you generate the
    weblogic-cmp-rdbms-jar.xml and webloigc-ejb-jar.xml files if given the ejb-jar.xml, the home, remote and bean classes and the database server information.
    The reason, I am asking this is because if you're using Hibernate, there is a hibernate tool that will generate the hbm.xml and persistence classes given a particular database information.
    I was wondering if there is the same thing in ejb development with weblogic 8.1 sp6?
    Yours,
    Desperate

    I think u r some confusion with productID and SuppliedID . primary key of one column( productId ) can be a foreign key of other table colum( SuppliedID). but foreign key( SuppliedID) can not be a primary key of second table .u declared SuppliedId as primary key . so ur mapping is incorrect.

  • Creating weblogic-cmp-rdbms-jar.xml from JDeveloper 10g

    Hi
    is any one aware if I can create the weblogic-cmp-rdbms-jar.xml from the Jdeveloper 10g. I know that it definitely does not have this deployment discriptor in the list.
    Is there any other way of creating this via JDeveloper.
    if not would it be a good feature to have?

    A schema for weblogic-cmp-rdbms-jar.xml may be registered and an XML document based on the schema generated.

  • Transaction Isolation Levels in weblogic-cmp-rdbms-jar.xml

    Hi All,

  • Ejb-jar.xml中的EJB QL和weblogic-cmp-rdbms-jar.xml中的WLQL

    我想问一下,在ejb-jar.xml文件中用EJB QL查询语言定义了相应的EJB QL查询语句后,在weblogic-cmp-rdbms-jar.xml文件中还需不需要用wlql语言来定义相应的查询语句呀?

    在Weblogic6.0中,如果你需要利用EJB2.0的EJBQL语言所不提供的
    ORDERBY排序功能,那么这时候可以在weblogic-cmp-rdbms-jar.xml中用WLQL覆盖它,一般情况下,在ejb-jar.xml中声明一个EJBQL方法就可以了,WLQL可有可无。

  • Column-map in weblogic-cmp-rdbms-jar.xml

    Hi,
    How to specify column-map for the following database tables:
    Table1: id,col2,col3. Primary key - id.
    Table2: m_id,description,col4,col5. Primay key - (m_id,col4).
    The relationship I specified is table1-has-many-table2. This is a 1 to m relation
    and
    Table1.id = Table2.m_id.
    I specified the following column-map
    <column-map>
    <foreign-key-column>m_id</foreign-key-column>
    <key-column>id</key-column>
    </column-map>
    But the server is throwing an exception that all the columns in table2 should
    me mapped.
    But in this case, I can join the tables with just id only. What should I specify
    for col4 map?.
    I can just reverse the mapping, but I am trying to test the boundaries of weblogic
    server.
    Is this case handled in weblogic server implementation?.
    I am testing relationship-role-map for ejb2.0 on weblogic server8.1 beta version.

  • Weblogic-cmp-jar.xml vs weblogic-cmp-rdbms-jar.xml

    We've recently upgraded from WLS 6.1 to 8.1.
    Can anyone clarify the difference between <b>weblogic-cmp-jar.xml</b> and <b>weblogic-cmp-rdbms-jar.xml</b>?
    The weblogic-cmp-rdbms-jar.xml format we've been using is essentially just a list of data base elements, but we may have been under-utilizing it.
    The weblogic-cmp-jar.xml seems more complex and useful.
    Thanks.

    You can reference the edoc at:

  • Entity Finder mothod takes run time String. How can I specify in CDATA of the weblogic-cmp-ejb-jar.xml

    Hi everyone,
    I have an CMP bean which has findByName(String). During deployment of the ejb
    I tell the bean use the WLQL such as
    (like string%), but I would like to pass the name when the user enter in the text
    box of the .html page then the user click on search, the servlet is called and
    process using ejb technique. If I specified (like Fre%) in the ejb despcriptor
    for one particular case( such as looking for all Fred's), it will not work for
    the user enters smith.
    for example: user enter: Fre in the text box.
    I would like to have the bean do the query for me like:
    --> select * from user where lastName like Fre%
    If I cannot tell in the CDATA field, does that mean I have to use BMP to write
    query that takes the name.
    Please help,
    Thanks in advance.

    Thanks Jim,
    I did exactly like in the example (like Name $0) Name is my cmp field, but this
    time it always returns one entity (same entity )regardless what I entered to search
    by name. So that means it did not take the parameter that defined in <find-param>
    of the weblogic-cmp-rdbm-jar.xml. Do you have any suggestion or idea to overcome
    this problem.
    Thanks Jim,

    Do i have to mention the connection Pool name anywhere .. My connection Pool name
    is sql7Pool and my datasource name which i have mentioned is sqlTx. I am using
    Sql server 7. I am deploying a jar file(not a war file) and accessng the EJB through
    a Servlet. Please any help would definitely be appreciated.
    Cheers

    I thought you were getting a class cast exception but the stack trace shows
    a NullPointerException on line 38 of your servlet code. I am not sure if the
    code that you have attached is the complete code or just snippets of your
    complete code. Anyways, counting 38 lines in the code you attached points to
    the line "mr =
    mh.create(request.getParameter("login"),request.getParameter("name"));"
    which could be because "mh" is null. Can you verify "mh" is not null and
    also "objRef" is not null.
    Attaching the stack trace for ClassCastException would be useful.

    Hope this info helps in solving my problem. Do i have to mention theconnection
    Pool name anywhere in the xml descriptor or am i missing anything here. iguess
    Connection Pool name is not required since we are mentioning the JNDI namein
    the xml descriptor. Bye for now.Awaiting your reply.
    Cheers
    Ashish.

    It is unlikely that your xml descriptors can cause class cast exceptions.
    How did you install the servlet? Can you attach the servlet code that
    might
    help. Also complete stack trace of the exceptions would be helpful.
