Offline Schema and EJB

Is there a way to generate an CMP EJB form an Offline Schema.
Thanks,
Alley

Hi Alley,
I'm afraid there is no functionality available yet that will allow you to do this.

OC4J 9.0.3 and EJB 1.1 deployments???

I can not deploy my ejb1.1 beans on 9.0.3 container.
OC4J crashes with an XML parse error as a null pointer exception.
If I remove my O-R mappings from my orion-ejb-jar.xml file, the container starts up ok (app wont run as it needs the mappings)
9.0.3 docs claim I should be able to use my 1.1 ejb in this ejb 2.0 container.
Solaris release notes for 9.0.3 claim I must migrate to ejb2.0
Someone else posted this same question but got no replies.
Anyone else deployed ejb1.1 with OR mappings in 9.0.3 successfully yet?
thanks

I have tried migrating to an ejb2.0 set of beans and ejb-jar.xml file.
With no <query> tags installed for my finders I notice that a typical finder produces this:

This is vastly different from the 1.1 orion-ejb-jar.xml which would list ALL column names in the finder - hence how am I going to do a findAll? The currently generated sql is way off. Deployment of the "ormap" demo also shows a lack of column names in the generated SQL finder methods in orion-ejb-jar.xml.
Further, as soon as I introduce the query in the 2.0 version of ejb-jar.xml, the container dies with a null pointer exception. Removing this from the ejb-jar and bean deploys. Useless, cause theres no finders though.
Also, attempts to add to the <finder-method query=...> tag yield container crashes with null pointers too.
This is not very robust to say the least. Can you provide names of jar files that would cause such exceptions?
When NO query tag is inserted in the ejb-jar file, attempts to run a sample client using findByPrimaryKey return successfully but use of findAll causes timeouts similar to whats described in
"finders giving "timeout expired waiting for an instance" after 0, 1, or 2 calls" in this same forum.
Heres the query out of the ejb-jar.xml file...
<query>
<query-method>
<method-name>findAll</method-name>
<method-params></method-params>
</query-method>
<ejb-ql>
SELECT OBJECT(o) from IspTb o
</ejb-ql>
</query>
IspTb is the <abstract-schema-name> Tables exist in db.
The full error...which prevents deployment of the ejbs and hence no rewrite of the orion-ejb-jar file.

Create tables in different database schemas using EJB 3 Entity Persistent

Hi All,
I would like to find out how to get the following tasks done using EJB 3.0 Java Entity Persistent:
( i ) Create tables in different schemas such as STUDENT under EDUCATION schema and table PATIENT in HOSPITAL schema. We can then reference them in SQL as EDUCATION.STUDENT and HOSPITAL.PATIENT.
( ii ) Reference these tables uniquely once they are created.
There are no pre-existing tables or naming conventions that needs to be adhere to in this situation.
I have no problem creating tables on the current schema in EJB 3.0 Java Entity Persistent.
Any suggestions would be appreciated.
Thanks,
Jack

Use the schema attribute of the Table annotation:
package javax.persistence;
@Target({TYPE}) @Retention(RUNTIME)
public @interface Table
   String name( ) default "";
   String catalog( ) default "";
   String schema( ) default "";
   UniqueConstraint
uniqueConstraints( ) default {};
}

IFS and EJB

There are two ways to search by 'section' in XML documents.
First, if you define an iFS content type whose name and structure matches the schema of your XML document, the iFS SimpleXMLParser will automatically decompose the XML document and store each section as attributes on the iFS object. Refer to the Oracle iFS Developer's Guide for instructions on creating new content types and parsing XML instances.
Second, you can store XML documents in iFS without parsing the XML using the Web UI upload via browse interface. Oracle iFS 1.0 is configured so that it uses interMedia text to index the XML document. Subsequently, you'll be able to execute content searches for the document using section criteria (e.g. content contains 'interMedia' within 'Title').

Forms pulling Multiple Records from an XML Schema and XML data files - Adobe LiveCycle Designer

I built a form in Adobe LiveCycle with an xml schema and data file. The problem is with how the form renders the xml data file.
I have a statement element that consists of about 6 fields (statementID, statementName, statementAddress, statementCountry, statementZip, statementDate, etc) of data in the schema that allows for multiple iterations - so one xml data file can contain multiple statements. These fields allow for null values.
But here's the problem: When any of the statements - say statement 2 of 6 - has a null value in one of the fields, if the xml data file doesn't have a placeholder
(example of placeholder: <statementName type="String"/> )in the xml for that field, my form pulls the field value from the NEXT statement.
This corrupts all the rest of the statement records, as this field is shifted up for all the rest.
I know that in the past I haven't needed a placeholder when a field was null. But I'm wondering if when the data allows for multiple records the xml data file needs to generate the placeholder. And where is the problem? In the Schema? The xml data file? My form? And the 64-thousand-dollar question: How to fix it?

If your <statement> element is the one that repeats, it should be bound to a subform with the binding string of something like $.statement[*]. Then in that subform should be your fields and they should have bindings of $.statementID, $.statementName, $.statementAddress, etc.

JDBC, JMS and EJB transactions - possible problem?

Hello,
          I am using Oracle 9, Weblogic 8.1 SP 4, MyEclipse and
          XDoclet.
          In my current project I have the following piece of code
          in one of my message driven beans (code cited as pseudocode
          without unnecessary details):
          * @ejb.bean name="MyMessageProcessor"
          * display-name="Display name for a MyMessageProcessor"
          * jndi-name="ejb/MyMessageProcessor"
          * description="Bean MyMessageProcessor"
          * destination-type="javax.jms.Queue"
          * transaction-type="Container"
          * acknowledge-mode="Auto-acknowledge"
          * subscription-durability="Durable"
          * generate="false"
          * @ejb.transaction type="Required"
          public class MyMessageProcessor implements MessageDrivenBean, MessageListener {
          public void onMessage(Message msg) {
               try {
                    //obtaining connections to two different databases via JNDi
                    java.sql.Connection connOne =
                    ((DataSource)ctx.lookup("DataSourceOne")).getConnection();
                    java.sql.Connection connTwo =
                         ((DataSource)ctx.lookup("DataSourceTwo")).getConnection();
                    // performing some UPDATEs and INSERTs on connOne and connTwo
                    // calling some other methods of this bean
                    //creating the reply JMS message and sending it to another JMS queue
                    Message msgTwo = this.createReplyMessage(msg)
                    this.queueSender.send(msgTwo);
                    //commiting everything
                    this.queueSession.commit();
               } catch (Exception ex) {
               try {
                    if (this.queueSession!=null) this.queueSession.rollback();
               } catch (JMSException JMSEx) {};
               this.context.setRollbackOnly();
          Some days ago (before the final remarks from my client) there used to be only one DataSource configurated on the basis of the
          connection pool with non-XA jdbc driver. Everything worked fine
          including the transactions (if anything wrong happend not only wasn't the replymessage sent, but also no changes were written
          to database and the incomming message was thrown back to the my bean's
          queue).
          When I deployed the second DataSource I was informed by an error message, that only one non-transactional resource may
          participate in a global transaction. When I changed both datasources
          to depend on underlying datasources with transatcional (XA) jdbc drivers, everything stopped working. Even if
          EJB transaction was theoretically successfully rolledbacked, the changed were written to the database
          and the JMS message wasn't resent to the JMS queue.
          So here are my questions:
               1. How to configure connection pools to work in such situations? What JDBC drivers should I choose?
               Are there any global server configurations, which may influence this situation?
               2. Which jdbc drivers should I choose so that the container was able to rollback the database transactions
               (of course, if necessary)?
               3. Are there any JMS Queue settings, which would disable the container to send message back to the
               queue in case of setRollbackOnly()? How should be the Queue configurated?
          As I am new to the topic and the deadline for the project seems to be too close I would be grateful
          for any help.
          This message was sent to EJB list and JDBC list.

Hi,
          I found these information extremely useful and helpful.
          The seperate transaction for sending messages was, of course, unintentional. Thanks a lot.
          Anyway, I still have some problems. I have made some changes to the
          code cited in my previous mail. These changes included changing QueueSessions
          to non-transactional. I also set the "Honorate global transactions" to true.
          I am using XA JDBC driver. After setting "Enable local transactions" to false
          (I did it, because I assume that JDBC transactions should be part on the global
          EJB transaction) I got the following error:
          java.sql.SQLException: SQL operations are not allowed with no global transaction by default for XA drivers. If the XA
          driver supports performing SQL operations with no global transaction, explicitly allow it by setting
          "SupportsLocalTransaction" JDBC connection pool property to true. In this case, also remember to complete the local
          transaction before using the connection again for global transaction, else a XAER_OUTSIDE XAException may result. To
          complete a local transaction, you can either set auto commit to true or call Connection.commit() or Connection.rollback().
          I have also inspected the calls of methods of bean inside of onMessage() method just to check, whether
          the transactions are correctly initialized (using the weblogic.transaction.Transaction class).
          My questions are as follows:
          1. Any suggestions how to solve it? I have gone through the google answers on that problem and only
          thing I managed to realize that JDBC must start its own transaction. Is there any way to prohibit it
          from doing that? Can using setAutocommit(true/false) change the situation for better?
          2. How to encourage the JDBC driver to be a part of EJB transaction?
          3. As I have noticed each of ejb method has its own transactions (transactions have different
          Xid). Each method of the bean has "required" transaction attribute. Shouldn't it work in such
          way that if already started transaction exists it is used by the called method?
          4. The DataSources are obtained in my application via JNDI and in the destination environment I will have slight
          impact on the configuration of WebLogic. What is least problematic and most common WebLogic configuration which would
          enable JDBC driver to participate in the EJB transaction? Is it the WebLogic configuration problem or can it be
          solved programmically?
          Currently my module works quite fine when "enable local transactions" for DataSources is set to true, but this way
          I am loosing the ability to perform all actions in one transaction.
          Any suggestions / hints are more than welcomed. This message was posted to jdbc list and ejb list.

Get error message "firefox is in offline mode, uncheck the work offline menu and try again " when trying to open firefox after downloading latest version of firefox

after downloading the latest version of firefox, when trying to open it I recieved the message, "Firefox is in offline mode. cannot browse web. Uncheck the work offline menu and try again".

Create XML dynamically from schema and Java bean

Hi,
I'm looking for suggestions on the best approach to create an XML file programatically from a schema and Java bean.
The schema used is not fixed and may vary with each request so a dynamic way to create the XML is required.
Is there an API available that allows me to achieve this easily? Any help would be appreciated to point me in the right direction.
Thanks.

XMLBeans or JAXB should work for you.

Can't i use xml schema and oledb data connection at the same time?

Hello to all and thanks in advance.I use xml schema and oledb data connection at the same time and the problem is that when I try to export the xml, the outcome is not what i expect.Without the oledb connection everything is ok (just the schema) and the xml complies with the schema.
Can't i have both schema and oledb and the exported xml be as i want it?

You can use both at the same time, but not gor Internet access if that's what you're asking.
Now there is a thing called Link Aggregation, which combines a number of interfaces for speed/redundancy, but it really only works locally, and then only with ALL special equipment in the route, and most likely OSX Server involved.
Sorry.

Looks okay to me. But then I have no idea of what those "problems" are that you mentioned. Was there a particular reason you didn't tell us what they are?

Just installed 4.0.1 and now "offline" appears and I can't connect at all

When I click on Firefox, the dialog box says:
Offline mode/
Firefox is currently in offline mode and can't browse the Web.
Uncheck the "Work Offline" menu item, then try again.
I am sending this on Safari, the only browser working on my computer now.
