startsWith and endsWith functions in Javascript

inside script tag,

var data = "Helloo Good Morning";
startsWith
String.prototype.startsWith = function(data)
{
return (this.match("^"+data)==data)
}

eg:
data.startsWith("Helloo");
returns true
-----------------------------------------------------------------------
endsWith
String.prototype.endsWith = function(data)
{
return (this.match(data+"$")==data)
}
eg:
data.endsWith("Helloo");
returns false;

----------------------------------------------------------
trim
String.prototype.trim = function()
{
return (this.replace(/^[\s\xA0]+/, "").replace(/[\s\xA0]+$/, ""))
}
eg:
var tm = data.trim();

Date showing wrong in JSF outputText or with dataTable

Some times in , h:outputText with dataTable or without , java.util.Date showing wrong, means one date before the actual date is showing.
We can solve this problem using Converter.
One example :

DateConverter.java

package com.converter;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
/**
* This class is is used to convert a date to dd-MMM-yyyy format
* @author jijo
*
*/
public class DateConverter implements Converter {
public String getAsString(FacesContext context, UIComponent c, Object object)
throws ConverterException {
if(object!=null && !object.toString().equals("")){
final Date date = (Date) object;
String dt=null;
if(date!=null){
SimpleDateFormat formatter=new SimpleDateFormat("dd-MMM-yyyy");
dt=formatter.format(date);
return dt;
}}
return null;
}
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2)
throws ConverterException {
return null;
}
}

In
faces-config.xml
<converter>
<converter-id>dateConvert<converter-id>
<converter-class>com.converter.DateConverter</converter-class>
</converter>



In your jsp page

<h:outputText value="#{item.onDate}" converter="dateConvert" />

Stream has already been closed; nested exception is java.sql.SQLException

Stream has already been closed; nested exception is java.sql.SQLException in Oracle.
Java - Oracle connectivity some times this exception will happen.
One of the reason of this exception is , the table contains a long(datatype) field.
eg: 'users' table contains a field 'age' long datatype.
To solve this problem , replace the 'long' field to 'number' datatype.

Check and Uncheck checkboxes using javascript

inside script tag

//this will mark all the checkboxes inside a form are checked.

//form1 is the form name
function checkAll() {

for(var i=0;i

if(document.forms['form1'].elements[i].type=='checkbox') {

document.forms['form1'].elements[i].checked=true; } } }
//this will mark all the checkboxes inside a form are unchecked.

//form1 is the form name

function uncheckAll() {

for(var i=0;i

if(document.forms['form1'].elements[i].type=='checkbox') {

document.forms['form1'].elements[i].checked=false; } } }
//form1 is the form name

----------------------------------------------------------------------
//this will mark the specified checkboxes inside a form are checked

//form1 -- formname

//checkboxname-- checkbox name

function selectAllFields()

{

var chk = document.form1.checkboxname;

for (i = 0; i < checked =" true">

var chk = document.form1.checkboxname;

for (i = 0; i

}

Deploy axis webservice in Jboss server

Download the axis.war from
http://ws.apache.org/axis/java/install.html
Put the axis.war in jboss\server\default\deploy folder.
Then deploy the webservice in the axis.war and deploy the webservice using the command,
java org.apache.axis.client.AdminClient ..\src\com\jijo\stubs\deploy.wsdd
then copy the server-config.wsdd file from axis.war/WEB-INF folder and put the file in your WEB-INF folder.

In short first deploy in axis.war and copy the server-config.wsdd file and put into your project/WEB-INF folder.

WebService using Apache axis

Download the following jar

axis.jar,axis-ant.jar,commons-discovery-0.2.jar,commons-logging-1.0.4.jar,jaxrpc.jar,
log4j-1.2.8.jar,saaj.jar,wsdl4j-1.5.1.jar.
Create one project eg: CalcTest and set classpath to theses jars.

Download the axis.war file from http://ws.apache.org/axis/java/install.html and put into your tomcat(webapps) or jboss(deploy) folder.

Create one interface

package com.jijo;
/**
* @author jijo
*
*/
public interface Calculator {
public int add(int x,int y);
public int subtract(int x, int y);
}

Create one class and implemet the Calculator interface
package com.jijo;
public class CalculatorImpl implements Calculator {
public int add(int x, int y) {
return x+y;
}
public int subtract(int x, int y) {
return x-y;
}
}
Compile the classes, and in command prompt:
java org.apache.axis.wsdl.Java2WSDL -o calculator.wsdl -n urn:com.jijo.Calculator -l http://localhost:8080/axis/services/calcservice com.jijo.Calculator
[This is for creating the WSDL(Java to WSDL)].

After this a wsdl file is created in you folder.
Then Create the Stubs based on this WSDL(WSDL to Java)
java org.apache.axis.wsdl.WSDL2Java -o ..\src -p com.jijo.stubs -s calculator.wsdl
Then the stubs is created .

Replace the
CalcserviceSoapBindingImpl.java to the following

/** * CalcserviceSoapBindingImpl.java * * This file was auto-generated from WSDL * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter. */
package com.jijo.stubs;
import com.jijo.CalculatorImpl;

public class CalcserviceSoapBindingImpl implements com.jijo.stubs.Calculator{ com.jijo.Calculator calculator = new CalculatorImpl(); public int add(int in0, int in1) throws java.rmi.RemoteException { return calculator.add(in0, in1); }
public int subtract(int in0, int in1) throws java.rmi.RemoteException { return calculator.subtract(in0, in1); }
}


create a jar eg: cal.jar based on the classes and put into axis.war/WEB-INF/lib folder
start the tomcat/jboss server.Then
Deploy into axis.war using ,
java org.apache.axis.client.AdminClient ..\src\com\jijo\stubs\deploy.wsdd

One server-config.wsdd file is created in the axis.war folder.
Then restart the server.
Check the wsdl file getting using,in browser
http://localhost:8080/axis/services/calcservice?wsdl

Create a client class

import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import com.jijo.stubs.CalculatorService;
import com.jijo.stubs.CalculatorServiceLocator;

public class CalcClient {
public static void main(String[] args) {
CalculatorService service = new CalculatorServiceLocator();
try {
int result = service.getcalcservice().add(10, 20);
System.out.println("Result :"+result);
result = service.getcalcservice().subtract(10, 20);
System.out.println("Result:"+result);
} catch (RemoteException e) {
e.printStackTrace();
} catch (ServiceException e) {
e.printStackTrace();
}
}
}

JBoss -- Memory configuration

In the jboss server , if out of memory exception ,then configure the following in
jboss/bin/run.conf file,

if [ "x$JAVA_OPTS" = "x" ]; then
JAVA_OPTS="-Xms512m -Xmx1024m -XX:PermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

Convert String to Blob

String data = "hello world";
java.sql.Blob blob = org.hibernate.Hibernate.createBlob(data.getBytes());

Convert Blob to String

byte[] bdata = blob.getBytes(1, (int)blob.length());
