There is no way to perform a true switch on a String in Java. With the arrival of JDK 5.0 and its implementation of enum, a reasonably close approximation of this can be done using the following code.
Create an enum :
public enum Months{ JAN, FEB, MAR, APRIL;}

I was testing my web application on FireFox5 , I faced “not enough arguments” issue. During investigation what I found is while opening the page we are hitting actual issues inside ‘addEventListener’ function. I searched web around behavior of ‘addEventListener’ in firefox and found that it expect third argument as well so I replaced below code locally and it worked for me =)
addEventListener(“load”, function(event) {
_init();
);
Today I was doing some code in which I need to update the TextArea text onclick of a list option. I noticed It was working fine in IE all the time but inside Firefox and Chrome it works for first time but next time don’t update the content.
I was using below code
function callMe(){
var optionValue=$(‘#serviceNm :selected’).attr(‘nits’);
$(“#serviceRqstNm”).text(”);
$(“#serviceRqstNm”).text(optionValue);
}

From couple of weeks in my brother’s machine he was getting Blue Dump screen with message “DRIVER_IRQL_NOT_LESS_OR_EQUAL”. Today to investigate I asked him to pass me the minidump files. Minidump are file that windows write for debugging purpose at below location:
%SystemRoot%\Minidump
in the above folder you will find files with ext .dmp
if you open this file with notepad or any other editor you will not be able to read it’s content.

I was coding last night and I have to get some information from Manifest file in filters. In order to read the Manifest I need the ServletContext. Using below code you can get the ServletContext inside Filter.
public class SomeFilter implements Filter {
FilterConfig config;public void setFilterConfig(FilterConfig config) {
this.config = config;
}public FilterConfig getFilterConfig() {
return config;
}public void init(FilterConfig config) throws ServletException {
setFilterConfig(config);
}// doFilter and destroy methods…
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {ServletContext context = getFilterConfig().getServletContext();
Manifest mManifest=new Manifest();
System.out.println(“Manifest “+mManifest.getBuildInfo(context));}
}
I was sending date “06-14-2011” in XML request, during it’s processing i got this parse error
Cannot parse date 06-14-2011 com.thoughtworks.xstream.converters.basic.DateConverter.fromString(DateConverter.java:97)
this is because Xstream by default don’t handle MM-dd-yyyy format. So we need to add one in order to make our format working.
String[] formats ={“MM-dd-yyyy”}; XStream xstream = new XStream(); xstream.registerConverter(new DateConverter(“MM-dd-yyyy”,formats)); Object obj=xstream.fromXML(inputXML)
This will resolve the issue. =)
I was writing a code to access DB2 in CICS where I encountered this error. This error encounters when you are trying to access a secured Db with default options. In order to get this working, you have to specify ‘securityMechanism’ property in your connection string with value as supported by server, see below:
jdbc:db2://SERVERNAME:3700/DB:securityMechanism=7;

I was trying to access Mainframe () DB2 using standalone application with “com.ibm.db2.jcc.DB2Driver” driver where I encountered the below error
java.lang.NoClassDefFoundError: com/ibm/crypto/provider/IBMJCE
Problem was that ibmjceprovider.jar was missing from my classpath and java.security file I added the jar file and then added below line in security file..it works.
security.provider.10=com.ibm.crypto.provider.IBMJCE
Today I faced a situation where I need to verify something though Java class in database . My problem was I have to do this inside unix shell script. I created the below solution to achieve that, I am posting here sample working code:
JAVA CLASS
public class Sample
{
public static void main(String args[])
{
//Do the complete logic and print the result using system out
System.out.println(“Sample Testing”);
}
}
Shell Script
#!/bin/sh
#
# Purpose: Demonstrate how to send an email from UNIX using mailx.
############################################################
# Example 1 – Simple:
echo “This is the body.”| mailx -s “mailx Test1” sample@sample.com
# Example 2 – Using Variables:
SUBJECT=”mailx Test2″
EMAIL_ADDRESS=”sample@sample.com“
BODY=”This is the body of the message.”
echo “$BODY” | mailx -s “$SUBJECT” “$EMAIL_ADDRESS”
