[EJB 3.0] - Insert value to a coloum mapped to primary table with many t
by kaviarasu
hi im using thre tables table 1 which is a primary table which has two secondry tables table 2 and table 3
i want to insert the values to the secondry table table3 which colom is mapped to primary table using manyto one annotation
Table structure
Table1
1)Productid
2)ReviewId-primary key
table3
1)Commentid---primarykey
2)reviewid--mapped with primary table
3)comments
table2
1)userentryid------primarykey
2)2)reviewid--mapped with primary table
i want to insert value in table3 only where the commentid is autogenerated
and userid is get from the session
but i cant able to set review id because it is mapped as oblect
how to insert the value
the example code is
@Table(name="TBL_REVIEWS")
| public class TblReviews implements Serializable {
| @Id
| @GeneratedValue(generator="SeqID")
| @SequenceGenerator(name="SeqID",sequenceName="TBL_REVIEWS_SEQ",allocationSize=1)
| @Column(name="REVIEW_ENTRY_ID")
| private Long reviewEntryId;
|
| @OneToMany(mappedBy="reviewEntryId",fetch=FetchType.EAGER,cascade={CascadeType.ALL})
| private Set<TblComments> tblCommentsCollection;
|
|
| public Set<TblComments> getTblCommentsCollection() {
| return this.tblCommentsCollection;
| }
|
| public void setTblCommentsCollection(Set<TblComments> tblCommentsCollection) {
| this.tblCommentsCollection = tblCommentsCollection;
| }
| //other getters and setters
|
|
@Table(name="TBL_COMMENTS")
| @Name("tblcomm")
| public class TblComments implements Serializable {
| @Id
| @GeneratedValue(generator="SeqID")
| @SequenceGenerator(name="SeqID",sequenceName="TBL_COMMENTS_SEQ",allocationSize=1)
| @Column(name="COMMENTS_ID")
| private Long commentsId;
|
| private String comments;
| @ManyToOne
| @JoinColumn(name="REVIEW_ENTRY_ID")
| private TblReviews reviewEntryId;
| //other getters and setters
|
| public TblReviews getReviewEntryId() {
| return this.reviewEntryId;
| }
|
| public void setReviewEntryId(TblReviews wEntrreviewEntryIdyId) {
| this.reviewEntryId = wEntrreviewEntryIdyId;
| }
when i try the code like this
@In(required=false)
| TblReviews tr=new TblReviews();
|
| @In(required=false)
| TblComments tblcomm;
| @Out(required=false)
| @RequestParameter
| Long rid4comm; (review entry id value)
|
| public void writeComment() {
| tr.setReviewEntryId(rid4comm);
| tblcomm.setReviewEntryId(tr);
| em.persist(tblcomm);
| }
it inserting the other values except reviewentryid in secondry table
how to achive it
thank u regards

[JBossWS] - Re: Accessing a Java JBossWS WebService from VBScript not wo
by gbc＠gmx.de
Yeah, got it done!
1. .Net doesn't have VBA or VBScript support as I read somewhere
2. MS Soap Toolkit is crap, at least in my opinion
3. I discovered a little (even for commercial concerns) usefull library for SoapIssues with VBScript, VB6.0, C++, eVB, eVC and C#: PocketSoap (See http://www.pocketsoap.com/pocketsoap/)
4. I needed to play around awhile, but finaly:
My WebService class:
| @Stateless
| @WebService
| @WebContext(contextRoot="/SimpleWebServices")
| public class SimpleWeb implements SimpleWebInterface {
|
| @WebMethod
| public boolean isAlive() {
| System.out.println("SimpleWeb.isAlive()");
| return true;
| }
|
| @WebMethod
| public String hello(@WebParam(name="name") String name) {
| System.out.println("SimpleWeb.helloWorld(): " + name);
| return "Hello " + name + "!";
| }
|
| }
|
Called by a Testscript PocketSimpleWeb.vbs:
| Option Explicit
|
| Dim service, ns
|
| service = "http://localhost:8080/SimpleWebServices/SimpleWeb?wsdl"
| ns = "http://webservice.simple/"
|
| WScript.Echo "isAlive(): " & isAlive(service, ns)
| WScript.Echo "hello('World'): " & hello("World", service, ns)
|
| ' Should return true
| function isAlive(wsdl, namespace)
| Dim f, p
| Set f = CreateObject("pocketsoap.Factory")
| Set p = f.CreateProxy(wsdl, namespace)
| isAlive = p.isAlive
| end function
|
| ' should return "Hello " & name & "!"
| function hello(name, wsdl, namespace)
| dim e, t
| set e = CreateObject("PocketSOAP.Envelope.2")
|
| e.setMethod "hello", namespace
| e.parameters.create "name", name
|
| set t = CreateObject("PocketSOAP.HTTPTransport.2")
| t.SOAPAction = ""
| t.Send wsdl, e.serialize
|
| e.parse t
| hello = e.parameters.item(0).value
| end function
|
Gives me what I want, even without @SOAPBinding(style = SOAPBinding.Style.RPC):
| C:\Data\Tests>cscript PocketWebService.vbs
| Microsoft (R) Windows Script Host Version 5.6
| Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.
|
| isAlive(): true
| hello('World'): Hello World!
|
Thanks for your help, the pieces of infos really helped me getting along.
I hope this example is usefull for others around here,

[JBoss jBPM] - Re: java.lang.OutOfMemoryError
by tinico
I don't know... But I've a bad news !!
In fact, the problem isn't solved... I think he problem come from JbpmConfiguration... In my portlet, I've this :
|
| public class Portlet extends GenericPortlet {
|
| static public JbpmConfiguration jbpmconf = null;
|
| public Portlet() {
| }
|
| public void init(PortletConfig config) throws PortletException {
| super.init(config);
| jbpmconf = JbpmConfiguration.getInstance();
| }
|
| public void processAction(ActionRequest request, ActionResponse response) throws PortletException, IOException
| {
| PortletMode mode = request.getPortletMode();
| if(mode.equals(PortletMode.VIEW))
| doViewAction(request,response);
| }
|
| public void doViewAction (ActionRequest request, ActionResponse response) throws PortletException, IOException
| {
| JbpmContext jbpmContext = jbpmconf.createJbpmContext();
|
| try {
| ... my code ...
|
| finally {
| jbpmContext.close();
| }
| }
|
| public void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
|
| JbpmContext jbpmContext = jbpmconf.createJbpmContext();
|
| try {
| ... my code ...
| }
| finally {
| jbpmContext.close();
| }
| }
|
| public void destroy() {
| jbpmconf.close();
| }
| }
|
When I change code of my portlet, the portlet container rebuild the portlet and reload jbmpConfiguration... But I don't undersatnd, the old jbpmconfig is staying in mémory...
So, if I put the jbpm lib in the server classpath, all is ok, beacause it always keep the jbpmConfiguration in mémory.
SomeOne has any idea to keep the jbpm lib in my WEB-INF lib without outOfMemory error ?? thanks !

Plain queries as "SELECT c FROM Category c" run trouble-free.
My setup:
JBoss AS 4.2.1
Seam 1.2.1
MySQL 5.0 DBMS
mysql-connector-java-5.0.7-bin.jar
Thanks for any help!
