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”
SQLCODE -204 is "object does not exist".
I was getting this error while executing a query, this was happening because I was using the SCHEMA name of Q7 database and executing the query inside Q0 db.
means not able to find table with given user id.
When I corrected the db name it works fine.
This error also appear when you are not using schema name in query.
The HttpSessionBindingListener interface is implemented when an object needs to be notified if it's being bound to a session or unbound from a session.
Objects implement this interface so that they can be notified when they are being bound or unbound from a HttpSession. When a binding occurs (using HttpSession.setAttribute()) HttpSessionBindingEvent communicates the event and identifies the session into which the object is bound. Similarly, when an unbinding occurs (using HttpSession.removeAttribute()) HttpSessionBindingEvent communicates the event and identifies the session from which the object is unbound.
This interface has two methods, that are notified when the status of the object has changed:
Note, this listener will not be declared in the deployment descriptor as the same as HttpSessionActivationListener interface. The container at runtime will introspect this object to see if it implements the HttpSessionActivationListener and/or HttpSessionBindingListener and fires appropriate events to the object.
These methods have a HttpSessionBindingEvent parameter that can be used to retrieve the session that the object was bound to and the name it was given in the session.
Events of this type are either sent to an object that implements HttpSessionBindingListener when it is bound or unbound from a session, or to a HttpSessionAttributeListener that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.
The session binds the object by a call to HttpSession.setAttribute and unbinds the object by a call to HttpSession.removeAttribute.
The methods of this object that are used to get the name that's assigned to the object, the session it's bound to, and the actual object:
