HTML/JAVASCRIPT: Creating a window in Javascript

Some times its an useful job to create a window with a new requirement. But , when we are in development room/area , we always remember any search engine to fine the solutions for any type of problem. Even I , also  following some of the search engine. 

But, it is a fact that I am always try to avoid this type of habits. Be , traceable  for finding any solution. This article is one of the mail memory & also my teaching my myself , that don't guess any coding is normal and easy , so don't remember.


So, below the topic:- code line put inside script tag

window.open('','','left=0,top=0,width=1000,height=780,toolbar=0,scrollbars=0,status=0');orwondow.open();

All parameters are not mandatory  to put with values. If you don't need any scrollbar,toolbar,status bar then you can put 0 as the value here, either put 1.

How to set print area in JSP/HTML page for printer

This is one the interesting topic related to print the specific data from a jsp/html page. Directly to printer, without other browser data. I have done a quite obvious way in javascript for set the print area for printing. I faced this problem in my development team with me, for set a specific area for print.

Caution:-  Use of JavaScript may not be  always acceptable, due to client. If user/client disable the script setting in browser these may not work properly. But, every browsers are support script by default.  

As we know, window. Print() is used for print in JavaScript. There are so many ways to do a printing task in jsp/html page. Out of all I have mentioned 2 process below with advantage & disadvantage.  Put the below function in script area of your page:-

Procedure-1

function setDivPrint(val){
var printdata=document.getElementById('printarea').innerHTML;
var srcOriginalContent=document.body.innerHTML;
document.body.innerHTML=printdata;
window.print();
document.body.innerHTML=srcOrigionalContent;
}

Here ‘printarea ‘ is the id of printable div. It has some limitation, with getting the cancel button click event and some more. I am not mentioning all here. But in procedure-2 is so eminent than procedure-1.

Procedure-2

function setDivPrint(val){
var printdata=document.getElementById('printarea').innerHTML;
var printwindow=window.open('','','left=0,top=0,width=1000,height=780,toolbar=0,scrollbars=0,status=0');
printwindow.document.write(printdata);
printwindow.document.close();
printwindow.focus();
printwindow.print();
printwindow.close();
}

Here ‘printarea ‘ is the id of printable div. .This method is recommended to use. In this method no need to get the cancel or print button event. Suppose the user click on cancel, then the main original page should come, but it may not coming with the Procedure-1 . So, No need to face this problem in Procedure-2.

Happy Learning.

MYSQL:How to create MySql Dumps using batch file (WINDOWS)

Too much ,, really in MYSQL finding complete solution like oracle & sql server is too difficult. That I have faced so many times with my development team. One of my colleague asked about the dumps creation using batch file. Really I searches many sites on internet with unexpected   results. Taking dumps using command line I have already post on my blog , but in this case I need a batch file for execution. And finally when I prepare it for serve , I was really happy and now I am sharing this happiness with all my visitors .  Below the code inside the batch file :-

cd "c:\Program Files\MySQL\MySQL Server 5.0\bin\"
mysqldump -hyourIPaddress -uyour_user_name -pyour_password yourdbname > d:\output_backup.sql
exit


Now create a batch file and paste the code above with host,username, password,database name and output file name for store data.

Example 1:-
cd "c:\Program Files\MySQL\MySQL Server 5.0\bin\"
mysqldump -hlocalhost -uroot -proot manojdb > d:\mybackupdumps.sql
exit

If you want to take all database backup/dumps you can also do by following code :-

cd "c:\Program Files\MySQL\MySQL Server 5.0\bin\"
mysqldump -hlocalhost -umyuname -pmypassword --all-databases > d:\myalldatabasedumps.sql
exit


MYSQL Reference manual provides so many options for using with mysqldump . Some of the most useful are below :-


--add-locks  is used for    Surround each table dump with LOCK TABLES and UNLOCK TABLES statements.

 --all-databases  is used for Dump all tables in all databases.

  

 --comments  is used for Add comments to the dump file.

--compact is used for produce more compact out put .

--ignore-table=db_name.tbl_name is used for Do not dump the given table



You can also follow mysql reference manual for dumps creation  by Click Here. 



Hope it will help you.

Java : Get Last inserted ID (Auto Increment) from Database Query

Really I faced lot of questions & problems related to this topic , basically when we are using mysql as the backend. But its quite obvious & simple for find the last inserted record id (Auto increment ) and primary key also from an insert query ( Not from a procedure). I am not using callable statement for achieve this task. Simple directly by query :-

You can retrive value by using:-

1. select last_insert_id()
2. RETURN_GENERATED_KEYS


Follow the example below:-


String query="insert into m_time_list(vchTime,vchGMT,createdDate) values('"+form.getTxtTime()+"','"+form.getRdbgmt()+"',curdate())";
            pstmt=connection.prepareStatement(query,Statement.RETURN_GENERATED_KEYS);
            sts=pstmt.executeUpdate();   
            rs=pstmt.getGeneratedKeys();
            int sid=0;
            while(rs.next()){
                sid=rs.getInt(1);
            }

Now , Sid contains the return inserted ID.



Hope it will help you.

Java : Causes of An Out Of Memory Error (Server Side )

Out Of Memory Error (OOME) can be solve.But what is actually it is !!!



The literal cause of an Out Of Memory Error is simple: a given Tomcat instance uses up all of the heap memory allocated to it, causing an application or server crash.

Thus, the errors themselves are not particularly puzzling. The reason why OOMEs have become such a persistent topic of discussion in the Apache Tomcat community is that they are difficult to trace to their root cause.

A stack trace will not show the cause, as the problem usually lies not with Tomcat, but the web application.

Meanwhile, the 'incorrect' web app code causing Tomcat to run out of memory is usually technically correct. That is to say, in any context other than a container managed environment, the code would be considered standard. It is easy to see why a developer might have trouble determining which 'correct' section of their code was incorrect.

Here are some of the most common root causes of an OOME:

• a simple case of the heap size being too small
• running out of file descriptors
• more open threads than the host OS allows
• code with high amounts of recursion
• code that loads a very large file into memory
• code that retaining references to objects or classloaders
• a large number of web apps and a small PermGen

Error: error java.lang.OutOfMemoryError: PermGen space..

Error: error java.lang.OutOfMemoryError: PermGen space..

In the area of J2EE development this error is one of the prominent & frequent which is not detected by any memory tool, so its interesting to avoid .PermGen space or heap size (outof memory) error can be avoided by following solutions.............

Solution-1
export CATALINA_OPTS=”-Xms512m -Xmx512m” (ksh/bash)
setenv CATALINA_OPTS “-Xms512m -Xmx512m” (tcsh/csh)

Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example,

set CATALINA_OPTS=”-Xms512m -Xmx512m” (Windows)

In catalina.bat or catallina.sh, you may have noticed CATALINA_OPTS, JAVA_OPTS, or both can be used to specify Tomcat JVM options. What is the difference between CATALINA_OPTS and JAVA_OPTS? The name CATALINA_OPTS is specific for Tomcat servlet container, whereas JAVA_OPTS may be used by other java applications (e.g., JBoss). Since environment variables are shared by all applications, we don’t want Tomcat to inadvertently pick up the JVM options intended for other apps. I prefer to use CATALINA_OPTS.

Solution-2

Change the Catalina.bat file in Tomcat/bin with following code.

Edit catalina.bat.If you do not have catalina.bat , contact me.

If you have the .bat file, open and search for CATALINA_OPTS

If the parameter is set to no value, set it to -Xms256m -Xmx512m -XX:MaxPermSize=256m and move it to the top of the file.

If the above doesn’t work revoke the changes did in the previous step, go to the last lines of the catalina.bat. Look out for %_EXECJAVA% %JAVA_OPTS%. It will be in a few lines.

Insert the parameter in those lines. Like the one below.

%_EXECJAVA% %JAVA_OPTS% -Xms256m -Xmx512m -XX:MaxPermSize=256m %DEBUG_OPTS% -Djava.endorsed.dirs=”%JAVA_ENDORSED_DIRS%” -classpath “%CLASSPATH%” -Dcatalina.base=”%CATALINA_BASE%” -Dcatalina.home=”%CATALINA_HOME%” -Djava.io.tmpdir=”%CATALINA_TMPDIR%” %MAINCLASS% %CMD_LINE_ARGS% %ACTION%

Here i have removed %CATALINA_OPTS% from them, to avoid setting parameters more than once.

It will really help you.I was in trouble with my team mates.

But now you can Enjoy...................
