[jboss-user] [EJB/JBoss] - throws javax.ejb.RemoveException, javax.ejb.EJBException, cau
Hi,
I am getting the following error when trying to use composite primary key for deletion of
a record.
2008-06-10 12:29:36,176 DEBUG
[org.jboss.ejb.plugins.cmp.jdbc.JDBCLoadEntityCommand.RCVlanLoopDetectedTableHome]
Executing SQL: SELECT rcVlanLoopDetectedVlanId, rcVlanLoopDetectedPortIndex,
rcVlanLoopDetectedValue FROM rcVlanLoopDetectedTable WHERE ()
2008-06-10 12:29:36,176 ERROR [org.jboss.ejb.plugins.LogInterceptor] EJBException in
method: public abstract void javax.ejb.EJBLocalObject.remove() throws
javax.ejb.RemoveException,javax.ejb.EJBException, causedBy:
java.sql.SQLException: Syntax error or access violation, message from server: "You
have an error in your SQL syntax; check the manual that corresponds to your MySQL server
version for the right syntax to use near ')' at line 1"
The code that I have written is:
primary key class
| public class RCVlanMacTablePK implements Serializable {
|
| Long rcVlanMacVlanId;
| String rcVlanMacAddr;
|
| public RCVlanMacTablePK() {
|
| this.rcVlanMacVlanId = null;
| this.rcVlanMacAddr = null;
|
| }
|
| public RCVlanMacTablePK(HashMap<String, Object> values) {
|
| this.rcVlanMacVlanId = Long.parseLong(values.get("rcVlanMacVlanId")
| .toString());
| this.rcVlanMacAddr = values.get("rcVlanMacAddr").toString();
|
| }
| }
In the session facade calling delete method for deleting the record in a table:
| public String delete(HashMap<String, Object> values) {
|
| try {
| RCVlanMacTablePK pk = pkLoader(values);
| home.remove(pk);
| } catch (RemoveException e) {
| log.info("RCVlan: Exception in deleted method " + e);
| } catch (EJBException e) {
| log.info("RCVlan: Exception in deleted method " + e);
| } catch (NumberFormatException e) {
| log.info("RCVlan: Exception in deleted method " + e);
| }
| return str;
| }
|
|
above pkLoader(values) is the method to load the primark key class and passing that
primary key class variable to the remove method and calling remove(Object primarykey)
method of EJBLocalHome Interface. ie home.remove(pk);
In the ejb-jar.xml:
| <entity>
| <ejb-name>RCVlanMacTableHome</ejb-name>
|
<local-home>com.sasken.sasems.server.beens.RCVlanMacTableHome</local-home>
|
<local>com.sasken.sasems.server.beens.RCVlanMacTableRemote</local>
|
<ejb-class>com.sasken.sasems.server.beens.RCVlanMacTableBean</ejb-class>
| <persistence-type>Container</persistence-type>
| <cmp-version>2.x</cmp-version>
| <abstract-schema-name>rcVlanMacTable</abstract-schema-name>
|
<prim-key-class>com.sasken.sasems.server.beens.RCVlanMacTablePK</prim-key-class>
| <reentrant>False</reentrant>
| <cmp-field>
| <field-name>rcVlanMacVlanId</field-name>
| </cmp-field>
| <cmp-field>
| <field-name>rcVlanMacAddr</field-name>
| </cmp-field>
| <cmp-field>
| <field-name>rcVlanMacRowStatus</field-name>
| </cmp-field>
| </entity>
|
I am getting the above error when executing the same. Please let me what needs to be done
for a composite primary key.
Thank you,
Mallikarjun.
