I am using below code to generate a UUID

TEXT(JEXIT("java.util.UUID","randomUUID"))

It is generating and output like- Ref.20305761 instaed of something like 322c2e7e-b8f3-43b5-9cfc-20c2b50d1fb7.

Could somebody help on how to go about achieving this?

Thanks!

It seems like your Java code is returning some sort of memory location reference.  Without posting your Java code, I'm not sure if we can help you.

I enclose a working example.

Thank-you.

By the way.  Great topic.

It really got me thinking, and I got to put my Java hat on for a change.

Thank-you.

Hi Paul,

Can you guide me how to make the JEXIT work in WTX design studio and launcher?

I have added jar in dtx.ini and CLASSPATH, but still not working.

Thanks

Hi Paul

I believe the direct JEXIT call is not able to achive the toString conversion.

Thanks much for a working solution!

I re-tested this example in Design Studio, Command Server and Launcher.  It worked in all environments.

Did you create a JAR file from the Test1.java example?  I enclose mine for convenience.

My dtx.ini file has:

[External Jar Files]
jar1=Y:\JavaProject1\testjexit.jar

Thank-you.

Yes, your example is working fine in my environment, but mine is not.

May I know which version you are using (JVM and WTX)?

I remembered last time I was having a Java version issue.

Thanks Paul.

I managed to make it work, but not sure what happened, maybe it's the version issue.

By the way, do you know how to pass more than 2 parameters to Java class in JEXIT?

Originally posted by: paul.brett

The JEXIT() examples with the product show:

=VALID(JEXIT("TestJExit", "Concat", "JExit ", "Example"), FAIL(LASTERRORMSG()))

Thank-you.

Hi Paul,

I am referring below the sample:

=VALID(JEXIT("JavaClass", "Function", "Param1 ", "Param2"), FAIL(LASTERRORMSG()))

How about if I need to pass more than 2 params to the function? (Param3, Param4,...)

It seems two is the maximum.

You could pass all of your parameters in 1, and then split inside the Java code:

=VALID(JEXIT("TestJExit", "Concat", "Param1|Param2|Param3|Param4 "), FAIL(LASTERRORMSG()))

Thank-you.

Hi ,

One example of parsing and splitting a parameter here ;

https://www.ibm.com/developerworks/community/forums/html/topic?id=e05068cc-997a-4204-8349-6f2eaddea76e&ps=25

=VALID(JEXIT("EJ.TestCases.CalculateTimeZone","getTimeZone",DATETOTEXT(CURRENTDATETIME("CCYYMMDDHH24MMSS+/-ZZ:ZZ")),"yyyyMMddHHmmssXXX!yyyy-MM-dd'T'HH:mm:ss.SSSXXX"),

 FAIL(LASTERRORMSG()+LASTERRORCODE())))

The second argument is delimited by a ! that we parse and split in the javacode .

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
public class CalculateTimeZone {
    public static String getTimeZone(String zone,String zone2) {
         //reset date
        Date date = null;
        String dateout =null;
                String part1 = null; 
                String part2 = null; 
          try {
                          String[] parts = zone2.split("!");
                part1 = parts[0]; 
                part2 = parts[1];
        DateFormat df = new SimpleDateFormat(part1);
        DateFormat dfout = new SimpleDateFormat(part2);
            date = df.parse(zone);
            dateout = dfout.format(date);
            return dateout;
       }
        catch (ParseException pe) {
            pe.printStackTrace();
        }
        return "Error parsing or formatting date.\r\nInput date given "+zone+"\r\nInput and output Format given : "+zone2+"\r\nParsed input format ="+part1+"\r\nParsed output format="+part2;
                
}
}

Hope this Help .
