[Clustering/JBoss] - Re: Communication between nodes
by bstansberry＠jboss.com
No, you can't get access to the JChannel, and if you did that send() call wouldn't work. HAServiceMBeanSupport provides a callMethodOnPartition method that lets you invoke an RPC on the group; you could pass the target node as a param.
If you can use AS 5.1 (now in CR1 release) HAPartition also exposes methods for making RPCs solely on target nodes:
/**
* Calls method synchronously on target node only.
* @param serviceName Name of the target service name on which calls are de-multiplexed
* @param methodName name of the Java method to be called on remote services
* @param args array of Java Object representing the set of parameters to be
* given to the remote method
* @param types The types of the parameters
* node of the partition or only on remote nodes
* @param targetNode is the target of the call
* @return the value returned by the target method
* @throws Exception Throws if a communication exception occurs
*/
public Object callMethodOnNode(String serviceName, String methodName,
Object[] args, Class[] types, long methodTimeout, ClusterNode targetNode) throws Throwable;
/**
* Calls method on target node only.
* @param serviceName Name of the target service name on which calls are de-multiplexed
* @param methodName name of the Java method to be called on remote services
* @param args array of Java Object representing the set of parameters to be
* given to the remote method
* @param types The types of the parameters
* node of the partition or only on remote nodes
* @param targetNode is the target of the call
*
* @throws Exception Throws if a communication exception occurs
*/
public void callAsyncMethodOnNode(String serviceName, String methodName,
Object[] args, Class[] types, long methodTimeout, ClusterNode targetNode) throws Throwable;
There's no convenience method to expose that via HAServiceMBeanSupport, but that's not hard for you to implement.

[Persistence, JBoss/CMP, Hibernate, Database] - Trying to cascade a delete operation
by lsToronto2009
I have a Company class:
| public class Company implements Serializable {
|
| ....
|
| @OneToMany (mappedBy="company", cascade=CascadeType.ALL)
| @JoinColumn(name="COMPANY_ID")
| private List<Address> addresses = new ArrayList<Address>();
| ...
| }
|
The intention is a company can have one to many addresses.
Here is the Address:
| public class Address implements Serializable {
| ....
|
| @ManyToOne
| private Company company;
|
| ...
| }
|
The behavior I want is if a Company is deleted, all the associated Addresses should be removed as well.
However when I delete a Company I get a constraint violation:
| com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`db`.`address`, CONSTRAINT `FK1ED033D44C674D5C` FOREIGN KEY (`company_id`) REFERENCES `company` (`id`))
|
I thought the cascade=CascadeType.ALL in the Company class would give me this.
What am I doing wrong?

[JBossWS] - Issue using XmlMixed, XmlRefrences, XmlRefrence annotations
by kyle.bober
I am having an issue with the XmlMixed, XmlRefrences, XmlRefrence annotations... Or so that is what I think is causing the issue.
I have a base class called CriteriaSO
| @XmlRootElement(name="Criteria")
| @XmlType(propOrder = {"sortType"})
| @XmlSeeAlso({IdCriteriaSO.class})
| public abstract class CriteriaSO {
|
| protected SortType theSortType;
|
| public CriteriaSO() {
| super();
| this.theSortType = KeywordAnalysisSortType.ASCENDING;
| }
|
| @XmlElement(name="SortType", required=true, nillable=false)
| public SortType getSortType() {
| return theSortType;
| }
|
| public void setSortType(SortType aSortType) {
| theSortType = aSortType;
| }
|
| }
|
I have a two classes that extend the CriteriaSO class ::
| @XmlRootElement(name="IdCriteria")
| @XmlType(propOrder = {"Ids"})
| public class IdCriteriaSO extends CriteriaSO {
|
| private static final long serialVersionUID = 20090430001L;
|
| private List<Integer> theIds;
|
| public IdCriteriaSO() {
| super(SortType.ASCENDING);
| this.theKeywordAnalysisIds = new ArrayList<Integer>();
| }
|
|
| @XmlElementWrapper(name = "Ids", nillable=false, required=true)
| @XmlElement(name = "Id", required = true, nillable = false)
| public List<Integer> getIds() {
| return theIds;
| }
|
| public void setIds(List<Integer> aIds) {
| theIds = aIds;
| }
| }
|
|
| @XmlRootElement(name="UserIdCriteria")
| @XmlType(propOrder = {"userIds"})
| public class UserIdCriteriaSO extends CriteriaSO {
|
| private static final long serialVersionUID = 20090430001L;
|
| private List<Integer> theUserIds;
|
| public UserIdCriteriaSO() {
| super(KeywordAnalysisSortType.ASCENDING);
| this.theUserIds = new ArrayList<Integer>();
| }
|
|
| @XmlElementWrapper(name = "userIds", nillable=false, required=true)
| @XmlElement(name = "userId", required = true, nillable = false)
| public List<Integer> getUserIds() {
| return theUserIds;
| }
|
| public void setUserIds(List<Integer> anUserIds) {
| theUserIds = anUserIds;
| }
| }
|
I then created a List wrapper to contain the CriteriaSO object instances like so ::
| @XmlRootElement(name="CriteriaList")
| @XmlSeeAlso({IdCriteriaSO.class, UserIdCriteriaSO.class})
| public class CriteriaListSO {
|
| private static final long serialVersionUID = 20090424001L;
|
| private List<CriteriaSO> theCriteria;
|
| public CriteriaListSO() {
| super();
| this.theCriteria = new ArrayList<KeywordAnalysisCriteriaSO>();
| }
|
|
| @XmlMixed
| @XmlElementRefs( {
| @XmlElementRef(name = "IdCriteria", type = IdCriteriaSO.class),
| @XmlElementRef(name = "UserIdCriteria", type = UserIdCriteriaSO.class) })
| public List<CriteriaSO> getCriteria() {
| return theCriteria;
| }
|
| public void setCriteria(List<sCriteriaSO> anCriteria) {
| theCriteria = anCriteria;
| }
| }
|
I have a web service method that takes a CriteriaListSO object as a parameter.
| @WebService(name="testService", serviceName="testService")
| @SOAPBinding(style=SOAPBinding.Style.DOCUMENT, use=SOAPBinding.Use.LITERAL, parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
| public class TestService {
|
|
| @WebMethod(operationName = "echoCriteria")
| @WebResult(name = "CriteriaList")
| @RequestWrapper(localName="echoCriteriaRequest")
| @ResponseWrapper(localName="echoCriteriaResponse")
| public CriteriaListSO echoCriteria(@WebParam(name = "CriteriaList")CriteriaListSO criteriaListSO) throws RemoteException {
|
| return criteriaListSO;
| }
| }
|
My issue is everytime I send a web service request to the echoCriteria web method with some CriteriaSO objects it doesn't set them in the CriteriaList object.
What I do see is one of the CriteriaList - ArrayList element's is being set to an object of type java.lang.String. And the contents of the String is the following
"\n" For each CriteriaSO object I add to the SOAP request it will add an additional \n to the string contents.
I am using JBoss 4.2.1
Any help or guidance would be appreciated. I have spent a few hours now on diffrent annotation configurations trying to figure this out.
