Success on Tomcat but Error on Jbpm Server
Hi all.
I have this code:
1. JSP file(DataTableTest.jsp):
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<f:view>
<h:form id="dataTableForm">
<h:dataTable border="1" id="dataTableTest" value="#{dataTableTest.data}" var="item">
<h:column>
<h:outputLabel value="#{item.label}"/>
<h:inputText value="#{item.text}" />
</h:column>
<h:column>
<h:commandButton action="#{dataTableTest.update}" value="Update" />
</h:column>
</h:dataTable>
<h:commandButton value="Preview" action="#{dataTableTest.previewMe}" />
</h:form>
</f:view>
2. Java1(DataTableTest.java):
package org.jbpm.webapp.bean;
import java.util.ArrayList;
import java.util.List;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
public class DataTableTest {
private DataModel myData=null;
private List listData=null;
public DataModel getData(){
if (myData==null){
myData=new ListDataModel();
}
if (listData==null){
listData=new ArrayList();
MyObject myObject=new MyObject();
myObject.setLabel("line1");
myObject.setText("Line 1");
listData.add(myObject);
myObject=new MyObject();
myObject.setLabel("line2");
myObject.setText("Line 2");
listData.add(myObject);
}
myData.setWrappedData(listData);
return myData;
}
public String previewMe(){
int origin=myData.getRowIndex();
System.out.println("1.Debug from Data table ===========");
for (int i=0; i<myData.getRowCount(); i++){
myData.setRowIndex(i);
System.out.println("line "+i+" : "+((MyObject)myData.getRowData()).getText());
}
System.out.println("2.Debug from Data table ===========");
myData.setRowIndex(origin);
return "home";
}
public String update(){
int originIndex=myData.getRowIndex();
if (originIndex>=0){
String item=((MyObject)myData.getRowData()).getText();
String label=((MyObject)myData.getRowData()).getLabel();
MyObject myObject=new MyObject();
myObject.setLabel(label);
myObject.setText(item);
listData.set(originIndex, myObject);
System.out.println("Index: " + originIndex + " data: " + myObject.getText());
}
return "home";
}
}
3. Java2(MyObject.java):
package org.jbpm.webapp.bean;
public class MyObject {
private String label;
private String text;
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
}Do not worry about faces-config.xml.
Here is my PROBLEM.
When i run this code on Tomcat Server, the Result as i want. But when i run this code with JBPM WEB APP(i insert my code into jbpm.war) on Jbpm Server, i have this error at start time of DataTableTest.jsp page.
