用于TRY的java托管bean：
public class TRY extends AbstractPageBean{
private String nomeClasse = this.getClass().getSimpleName();
private String distrib = getUserBean().getCurrentDatasource();
private String username = getUserBean().getUser();
private Date startDate;
private Date endDate;
private DropDown dropDown1;
private Logger logger;
public TRY() {
logger = Logger.getLogger(getClass());
logger.debug("Class TRY....");
}
@Override
public void init() {

}
TRY2的java托管bean：
public class TRY2 extends AbstractPageBean{
private String nomeClasse = this.getClass().getSimpleName();
private String distrib = getUserBean().getCurrentDatasource();
private String username = getUserBean().getUser();
private Logger logger;
public TRY2() {
logger = Logger.getLogger(getClass());
logger.debug("Class TRY2....");
}
@Override
public void init() {
super.init();
try {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, LogMessages.INIT_OK), null);
} catch (Exception e) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, "KO: " + e.getMessage()), null);
throw e instanceof FacesException ? (FacesException) e : new FacesException(e);
}
}
@Override
public void preprocess() {
try {
getUserBean().navigationStatus();
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.PREPROCESS, "OK"), null);
} catch (IOException e) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.PREPROCESS, "KO: " + e.getMessage()), null);
}
}
@Override
public void prerender() {
try {
logger.debug("Class TRY2....PRERENDER");
getUserBean().navigationStatus();
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.PRERENDER, "OK"), null);
} catch (Exception e) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.PRERENDER, "KO: " + e.getMessage()), null);
}
ALGUISessionBean session = getALGUISessionBean();
if (session.isError()) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.PRERENDER, LogMessages.PRERENDER_VAL_ER), null);
session.setError(false);
} else {
resetOwnSessionVars();
}
}
@Override
public void destroy() {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.DESTROY, LogMessages.DESTROYED), null);
}
/* -------------------
* - GETTER & SETTER -

protected ALGUISessionBean getALGUISessionBean() {
return (ALGUISessionBean) getBean("ALGUISessionBean");
}
protected UserBean getUserBean() {
return (UserBean) getBean("UserBean");
}
}
}
和face-config.xml中的naviagion规则
<navigation-rule>
<from-view-id>/TRY.jsp</from-view-id>
<navigation-case>
<from-outcome>TRY2</from-outcome>
<to-view-id>/TRY2.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<managed-bean>
<managed-bean-name>TRY</managed-bean-name>
<managed-bean-class>web.TRY</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>TRY2</managed-bean-name>
<managed-bean-class>web.TRY2</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
记录器告诉我：
logger.debug("Class TRY....button1_action ");
logger.debug("Class TRY....button1_action return ");
所以这意味着它进入方法button_click
我看到它记录：
logger.debug("Class TRY2....");
logger.debug("Class TRY2....PRERENDER");
所以这意味着它进入了bean TRY2
但是在我看不到页面TRY2之后为什么？
我看到javascript说：
<script type="text/javascript">new webui.suntheme4_2.body('/TRY2.jsp', '/sam-fe-web/faces/TRY2.jsp',null,null,'com_sun_webui_util_FocusManager_focusElementId',true);</script></body></html>
Uncaught TypeError: undefined is not a function
任何帮助？
没有人真的非常感谢你......
解决方案是添加
private void _init() throws Exception {
}
private Page page1 = new Page();
public Page getPage1() {
return page1;
}
public void setPage1(Page p) {
this.page1 = p;
}
private Html html1 = new Html();
public Html getHtml1() {
return html1;
}
public void setHtml1(Html h) {
this.html1 = h;
}
private Head head1 = new Head();
public Head getHead1() {
return head1;
}
public void setHead1(Head h) {
this.head1 = h;
}
private Link link1 = new Link();
public Link getLink1() {
return link1;
}
public void setLink1(Link l) {
this.link1 = l;
}
private Body body1 = new Body();
public Body getBody1() {
return body1;
}
public void setBody1(Body b) {
this.body1 = b;
}
private Form form1 = new Form();
public Form getForm1() {
return form1;
}
public void setForm1(Form f) {
this.form1 = f;
}
private Link link2 = new Link();
public Link getLink2() {
return link2;
}
public void setLink2(Link l) {
this.link2 = l;
}
和
public void init() {
super.init();
logger.debug("Classe di prova....INIT");
try {
_init();
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, LogMessages.INIT_OK), null);
} catch (Exception e) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, "KO: " + e.getMessage()), null);
throw e instanceof FacesException ? (FacesException) e : new FacesException(e);
}
}
答案 0 :(得分：0)
add this into the TRY2.java class
private void _init() throws Exception {
}
private Page page1 = new Page();
public Page getPage1() {
return page1;
}
public void setPage1(Page p) {
this.page1 = p;
}
private Html html1 = new Html();
public Html getHtml1() {
return html1;
}
public void setHtml1(Html h) {
this.html1 = h;
}
private Head head1 = new Head();
public Head getHead1() {
return head1;
}
public void setHead1(Head h) {
this.head1 = h;
}
private Link link1 = new Link();
public Link getLink1() {
return link1;
}
public void setLink1(Link l) {
this.link1 = l;
}
private Body body1 = new Body();
public Body getBody1() {
return body1;
}
public void setBody1(Body b) {
this.body1 = b;
}
private Form form1 = new Form();
public Form getForm1() {
return form1;
}
public void setForm1(Form f) {
this.form1 = f;
}
private Link link2 = new Link();
public Link getLink2() {
return link2;
}
public void setLink2(Link l) {
this.link2 = l;
}
以这种方式编辑init（）：
public void init() {
super.init();
logger.debug("Classe di prova....INIT");
try {
_init();
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, LogMessages.INIT_OK), null);
} catch (Exception e) {
log(LogMessages.getLogString(username, distrib, nomeClasse, LogMessages.INIT, "KO: " + e.getMessage()), null);
throw e instanceof FacesException ? (FacesException) e : new FacesException(e);
}
}
