I've been looking for a solution and on the following posting a sugestion is posted however during compilation it brakes. http://www.jboss.org/index.html?module=bb&op=viewtopic&t=54267 It breaks as Jboss generates a line: anonymous wrote : pk = new java.lang.Object(this.getId()); Which can't be compiled under java 5.0 or is simply wring .. Could anybody please provide me how to get CMR working here?

Hi,
thanks again. Now the Bean works. Here is the summary (XDoclet):
Bean-Xdoclet-Descriptor
|
| /**
| * @ejb.bean name="Kunde" display-name="Name for KundeBean"
| * description="Description for KundeBean" jndi-name="ejb/Kunde"
| * type="CMP" cmp-version="2.x" view-type="local"
| *
| * @ejb.pk class = "java.lang.Object" generate = "false" ejb.value-object
match =
| * "*" name = "KUNDE"
| *
| * @ejb.value-object match = "*" name = "Kunde"
| *
| * @jboss.persistence table-name = "KUNDE" read-only = "false" create-table
=
| *"false" remove-table = "false"
| *
| * @jboss.entity-command name="postgresql-fetch-seq"
| *
class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCPostgreSQLCreateCommand"
| *
| * @jboss.unknown-pk auto-increment = "true" column-name = "KUNDE_ID"
jdbc-type =
| * "BIGINT" sql-type = "INT8" class = "java.lang.Object"
| *
| */
Entity Bean Methods
|
| /**
| * @ejb.create-method view-type = "local"
| *
| * @throws CreateException
| */
| public java.lang.Object ejbCreate(String firmenname, String strasse,
| String plz, String ort, String telefon, String fax,
| String webSeiteURL, String email) throws
CreateException {
| //
| return null;
| }
|
| // Important: NO Setter/Getter/Xdoclet stuff for the primary-field !
|
Using Session Bean creating the entity bean
| /**
| * @ejb.interface-method view-type = "both"
| */
| public java.lang.Object createKunde(String firmenname, String strasse,
| String plz, String ort, String telefon, String fax,
| String webSeiteURL, String email) throws
ECannotCreateException {
|
| KundeLocal myKundeLocal = null;
|
| try {
| Logger.log("KundeMgrBean.createKunde()");
| myKundeLocal = this.myKundeLocalHome.create(firmenname,
strasse,
| plz, ort, telefon, fax, webSeiteURL,
email);
|
| Logger.log("Neue Kundenid: " +
myKundeLocal.getPrimaryKey());
| return myKundeLocal.getPrimaryKey();
|
| } catch (CreateException e) {
| throw new ECannotCreateException("Cannot create 'Kunde'
"
| + firmenname, e);
| }
| }

take a look at my other posting on the Informix/auto-increment http://www.jboss.com/index.html?module=bb&op=viewtopic&t=61244 You don't have to return anything in ejbCreate(), just return null lets say you are creating your entity bean from a session bean using blaHome.create() which returns blaLocal. you can always get the primary key on that object.

Hi Based on my search in the forum I gathered the following - On the entity level you need to specify the following tag @jboss.entity-command * name="informix-serial" * class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCInformixCreateCommand" in your case name = postgresql-fetch-seq and the class would be org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCPostgreSQLCreateCommand an on you getId() method you need to specify the following tag @jboss.persistance auto-increment ="true" you can see the result of these two steps in your jbosscmp-jdbc.xml on the entity you will get and on the field you will get the I did all of that for my entity and I mange to deploy it successfully BUT whenevr I try to create an new enity.. I get the following exception 22:17:50,126 ERROR [MyEntity] Could not create entity java.sql.SQLException: Primary key on table (mytable) has a field with a null key value. at com.informix.jdbc.IfxSqli.addException(IfxSqli.java:3082) at com.informix.jdbc.IfxSqli.receiveError(IfxSqli.java:3396) at com.informix.jdbc.IfxSqli.dispatchMsg(IfxSqli.java:2259) at com.informix.jdbc.IfxSqli.receiveMessage(IfxSqli.java:2179) at com.informix.jdbc.IfxSqli.executeCommand(IfxSqli.java:721) at com.informix.jdbc.IfxResultSet.executeUpdate(IfxResultSet.java:305) at com.informix.jdbc.IfxStatement.executeUpdateImpl(IfxStatement.java:882) >From the postings I feel that these two steps are enough (give it a try it >might work for you) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3869316#3869316 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3869316 --- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
