[jboss-user] [JBoss Seam] - Help: get exception when using EL to reference a EJB member
Hi,
I am new to Seam. I am playing with the hotel example. I modified main.xhtml to use my
own search bean.
| ....
| <h:form id="searchCriteria">
| <fieldset>
| <h:inputText id="searchString"
| value="#{edaSearch.searchString}"
| style="width: 165px;">
| <a:support event="onkeyup"
actionListener="#{edaSearch.find}" reRender="searchResults" />
| </h:inputText>
| </fieldset>
| .....
|
I got the follwoing exception:
| /main.xhtml @23,92 value="#{edaSearch.searchString}": Exception getting
value of property searchString of base of type :
org.javassist.tmp.java.lang.Object_$$_javassist_117
|
The follwoings are the my classes. They are very similar to HotelSearching.java and
HotelSearchingAction.java
Searching.java
| package com.ericsson.ems;
|
| import javax.ejb.Local;
|
| @Local
| public interface Searching {
| public int getPageSize();
| public void setPageSize(int pageSize);
|
| public String getSearchString();
| public void setSearchString(String searchString);
|
| public String getSearchPattern();
|
| public void find();
| public void nextPage();
| public boolean isNextPageAvailable();
|
| public void destroy();
| }
|
EdaSearchingAction.java
| @Stateful
| @Name("edaSearch")
| @Scope(ScopeType.SESSION)
| @Restrict("#{identity.loggedIn}")
| public class EdaSearchingAction implements Searching {
|
| @PersistenceContext
| private EntityManager em;
|
| private String searchString;
| private int pageSize = 10;
| private int page;
|
| @In
| Eda eda;
|
| @DataModel("searchList")
| private List<Eda> list;
| @DataModelSelection
| private Eda selObj;
|
| @Logger
| private Log log;
|
| public void find() {
| page = 0;
| queryEdas();
| }
|
| public void nextPage() {
| page++;
| queryEdas();
| }
|
| private void queryEdas() {
| list = em.createQuery("select e from Eda e where lower(e.name) like
#{pattern} or lower(e.ipAddr) like #{pattern}")
| .setMaxResults(pageSize)
| .setFirstResult( page * pageSize )
| .getResultList();
| }
|
| public boolean isNextPageAvailable() {
| return list!=null && list.size() == pageSize;
| }
|
| public int getPageSize() {
| return pageSize;
| }
|
| public void setPageSize(int pageSize) {
| this.pageSize = pageSize;
| }
|
| @Factory(value="pattern", scope=ScopeType.EVENT)
| public String getSearchPattern() {
| return searchString==null ?
| "%" : '%' +
searchString.toLowerCase().replace('*', '%') + '%';
| }
|
| public String getSearchString() {
| return this.searchString;
| }
|
| public void setSearchString(String searchString) {
| this.searchString = searchString;
| }
|
| @Destroy @Remove
| public void destroy() {}
| }
|
Am I missing something?
Thanks in advance for your help.
