BIRT Viewer in Tomcat

BIRT Viewer in Tomcat

BIRT is a powerful and open source reporting tool in java and its easy and compatible.

To install BIRT viewer firstly we should have tomcat server, if you don’t have please download the tomcat from https://tomcat.apache.org/download-80.cgi and it’s better to use a binary distribution rather installer.

After configuring tomcat, we should download the birt viewer.

Go to http://download.eclipse.org/birt/downloads/build.php?build=R-R1-4.6.0-201606072112

And Download the file under “Report Engine OSGi Deployment” file named
birt-runtime-osgi-4.6.0-20160607.zip

After successful download of the file, Unzip the file and you can see all the files as below.

Steps to be down after downloading the file.

1.       Now the birt.war file should be copied into tomcat webapps.

2.       And copy the jar files into tomcat lib.

If you are using mysql database, you should put mysql-connector-java-5.1.30.jar

If you are using mongodb database so you should put mongodb-driver-3.3.0.jar

Finally, we should copy commons-logging-1.2.jar

3.       We should unzip the birt.war and place in a folder of the name you want. Here I placed in birt folder.

4.       For Mongo DB users We should go to apache-tomcat-7.0.42\webapps\birt\WEB-INF\platform\plugins and need to remove org.eclipse.birt.data.oda.mongodb_4.6.0.v201606072122.jar and need to update the new one with mongo-java-driver-2.13.1.jar

And that’s it the configuration has been done.

Now we need to check the birt in tomcat.

1.       Go to tomcat bin directory and start the tomcat by using startup batch file.

2.       And open the browser and type in http://localhost:8080/birt/

3.       You can see the page as below.

4.       So, birt has been installed in tomcat now.

5.       And we can check the sample report by clicking on the link View Example on the same page we can see

6.       Now we will check the report which we have made in eclipse. So, we should place our files in the tomcat/weapps/birt/test1.rptdesign

7.       Now, in browser http://localhost:8080/birt/frameset?__report=test1.rptdesign

Now you can see the report

8.       Now we can place as many reports as we want and see on the server also.

Happy Coding with BIRT… Enjoy!!

JAVA – How To Calculate An Age From A Date Of Birth (DOB)

The following code illustrates how to derive an age from a given DOB.

This example uses the DOB format YYYY-MM-DD.

This can be altered to any format by changing the substrings taken from the original DOB input.


=======================================================================

String dob = “1990-05-07″;

//TAKE SUBSTRINGS OF THE DOB SO SPLIT OUT YEAR, MONTH AND DAY
//INTO SEPERATE VARIABLES
int yearDOB = Integer.parseInt(dob.substring(0, 4));
int monthDOB = Integer.parseInt(dob.substring(5, 7));
int dayDOB = Integer.parseInt(dob.substring(8, 10));

//CALCULATE THE CURRENT YEAR, MONTH AND DAY
//INTO SEPERATE VARIABLES
DateFormat dateFormat = new SimpleDateFormat(“yyyy”);
java.util.Date date = new java.util.Date();
int thisYear = Integer.parseInt(dateFormat.format(date));

dateFormat = new SimpleDateFormat(“MM”);
date = new java.util.Date();
int thisMonth = Integer.parseInt(dateFormat.format(date));

dateFormat = new SimpleDateFormat(“dd”);
date = new java.util.Date();
int thisDay = Integer.parseInt(dateFormat.format(date));

//CREATE AN AGE VARIABLE TO HOLD THE CALCULATED AGE
//TO START WILL – SET THE AGE EQUEL TO THE CURRENT YEAR MINUS THE YEAR
//OF THE DOB
int age = thisYear – yearDOB;

//IF THE CURRENT MONTH IS LESS THAN THE DOB MONTH
//THEN REDUCE THE DOB BY 1 AS THEY HAVE NOT HAD THEIR
//BIRTHDAY YET THIS YEAR
if(thisMonth < monthDOB){
age = age – 1;
}

//IF THE MONTH IN THE DOB IS EQUEL TO THE CURRENT MONTH
//THEN CHECK THE DAY TO FIND OUT IF THEY HAVE HAD THEIR
//BIRTHDAY YET. IF THE CURRENT DAY IS LESS THAN THE DAY OF THE DOB
//THEN REDUCE THE DOB BY 1 AS THEY HAVE NOT HAD THEIR
//BIRTHDAY YET THIS YEAR
if(thisMonth == monthDOB && thisDay < dayDOB){
age = age – 1;
}

//THE AGE VARIBALE WILL NOW CONTAIN THE CORRECT AGE
//DERIVED FROMTHE GIVEN DOB
System.out.println(age);
