Java method call to encrypt data field (type is string)

SrinivasaRao

Hi,

I have a java method which will encrypt the given string. Please refer below

public static String encrypt(String stringToEncrypt) throws Exception
{
//Here it will do some encrypt operation
return encryptedHexString;
}
i need to call this method for each detail row in my birt report.
Ex:- I should display the employee no is in encrypted

Now i am in confusion how to call the above method on create of datafield.

Can anybody please help me. I have very urgent requirement to do this.

Any help would be mostly appreciated.

FYI: i am using birt 2.5.1

Thanks,
Srinivas

There are actually a couple of ways to do this.

I am assuming you have a JAR file with this method. In which caase, you put this JAR file in your classpath, then you call it with using the Packages.<packageName>.encrypt(String) method. So, lets say your class is called EncyptClass, in pacakge. com.birt.encrypt. You would call it in your expression like so:

////////////////////////////////////////////////////////////
var encrypt = new Packages.com.birt.encrypt.EncryptClass();

var returnstring = encrypt.encrypt(row["employeeNumber"]);

returnstring;
////////////////////////////////////////////////////////////

Another way you can do this is to create a BIRT user function extenstion plugin. Then, when you run BIRT, this method will appear in the Javascript functions at the bottom of the Expression Editor, just like the BIRTComp, date, and Javascript functions do.
