Hi,

I am moving my project from Websphere to Tomcat server. But getting the following exceptions in the log. Can anyone help me to resolve this.

Resolved.

Hi,

I am new to Spring. Got the following issue. Please help to understand.

//TestBean.java ------------------------------------------------ package com.spring.aop.before; public class TestBean { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } } //Advice -------------------- package com.spring.aop.before; import java.lang.reflect.Method; import org.springframework.aop.MethodBeforeAdvice; public class TestBefore implements MethodBeforeAdvice { @Override public void before(Method arg0, Object[] arg1, Object arg2) throws Throwable { System.out.println("\n Method name::" + arg0 + "\n Argument List::" + arg1[0] + "\n Target::" + arg2); } } //Main Class package com.spring.aop.before; import org.springframework.aop.framework.ProxyFactory; public class TestBeforeAOP { public static void main(String args[]){ TestBean bean = new TestBean(); ProxyFactory factory = new ProxyFactory(); factory.addAdvice(new TestBefore()); factory.setTarget(bean); TestBean bean1 = (TestBean)factory.getProxy(); bean1.setName("ABCCDDE"); System.out.println(bean1.getName()); } }

On executing this, I am getting following exception:

Can anybody tell me the reason ?

Does anybody know about the api to use or the link giving details about writing java program to send sms.

Does anyone know how to include a dll file in a java webservice project.

Hi,

I am not able to transfer the data from txt to oracle table using sqlldr. If I execute the same command from cmd, it executes fine but does not work if I execute from java code.

Please find the code below
try { String[] cmd = new String[5]; Runtime rt = Runtime.getRuntime(); String osName = System.getProperty("os.name"); System.out.println("Operating System: " + osName); String sqlLoaderCommand = data.getProperty("command"); //sqlLoaderCommand=sqlLoaderCommand+" control="+controlFilePath; System.out.println("sqlLoaderCommand " + sqlLoaderCommand); if (osName.equals("Windows XP")) { cmd[0] = "cmd.exe"; cmd[1] = "/C"; cmd[2] = "set ORACLE_HOME = d:\\oracle\\ora92"; cmd[3] = "set PATH=d:\\oracle\\ora92\\bin"; cmd[4] = "sqlldr abc@dev\\x10 control='D:\\loader.ctl'"; } System.out.println("Before executing rt."); Process proc = rt.exec(cmd); // any error? int exitVal; exitVal = proc.waitFor(); System.out.println("ExitValue: " + exitVal); if (exitVal != 0) { System.out.println("The command line job did not execute successfully"); } else { System.out.println("The command line job executed successfully."+exitVal); } } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }



loader.ctl ----------------------- load data infile 'datafile.csv' into table emp fields terminated by "," optionally enclosed by '"' ( empno, empname, sal, deptno )

Please help to resolve it.

Hi,

I've an xml file containing all relevant info relate to class - like class name, methods, attributes. My question is how can I convert that into java file.

Thanks,

Hi,

I've got a good experience of 4 years in java and have been on bench for sometime due to lack of projects in our organization. I am planning to switch over to some other company but thinking of the recession prevents me from taking any concrete step.

Is it the right time to make a switch or should I wait for some time. I am working in India and there are few good openings going on but the current market scenario scares me.

Please advice.

Thanks,
Ritu

When I say get(index) method is better than iterators, I consider only Vector and ArrayList classes for n number of records. This does not includes LinkedList.

Suppose you have a List of 100 elements. Do you want to retrieve all 100 elements using index method...that is not true right.
So iterator will give you fast retrieving of data from List

Main reason is that when you use iterator,you never end up in any NoSuchElementException which usally arises when you use direct index to fetch a element which is not present.Its a safer way to retrive elements.

Well, I guess accessing by index is much faster than using Iterator and secondly, it does not throw NoSuchElementException. It throws IndexOutOfBoundsException. Please do not reply if you are confused.

My question still remains unanswered.

Why do we have iterators in subclasses of List interface(i.e ArrayList, Vector and LinkedList), when we can access the elements using index number?

We implement readObject(ObjectInputStream)/writeObject(ObjectOutputStream) in a class implementing Serializable interface to customize the serialization process. Now my question is:

1) Why are we supposed to provide implementation of these methods, when the Serializable interface is a marker interface. Where these methods come from ? Why the method signature should be like this.

2) When should we use serialization and Externalizable interface, when the customization of serialization can be achieved by either of them.

We have a clone() defined in Object class. If we try to execute a class overriding clone(), it throws CloneNotSupportedException. But if we implement Cloneable interface(which is a marker interface), everything goes fine. Now the question is, why do not we have a clone() in Cloneable interface rather then in Object class.

Is it in the Object only because we require a default implementation of a clone() and since Object is the superclass, so we cannot somehow implement that interface in Object class. But then Why do we require a Cloneable Interface at all. We can override its implementation in our subclass also.

Kindly help me to clarify my doubts
