String Tokenizer

[raphy]

Hello,

I would like to tokenize my string separated by ";".

Is it possible to use StringTokenizer with iReport?

Thanks for your reply

Maybe if you explain a bit what your plans are we could answer.

 

As a first guess it's possible using custom coding...

Hello,

I am using a custom data source and using a field named "person". This field containing firstname, lastname, phone etc.. as string and each values separated by ";".

 

My own datasource class containing getFildValue() returns a person's value as a string correctly.

 

The question:

How can I tokenize the person's string value to retrieve all separate data. (firstname, lastname, phone etc.. )

 

Thanks for your reply

An idea could be to write a java class (i.e. MyUtilities) with a static method (i.e. getToken()) working as follows:

 

getToken( String str, int tokenNum)

 

then you can use this class in your expressions:

 

MyUtilities.getToken($P{PersonField}, 1)

 

(this expression will take the first token from your person string).

Hello,

Thanks for your prompt reply.

I do as you mentioned in your reply. But when I compiling with iReport there is no error and when run my application there is an error message as follows:

 

Errors were encountered when compiling report expressions class file:

Tools cannot be resolved

value = (java.lang.String)(Tools.getName());

 

The method implemented in my Tools.class is:

public static final String getName ()

{

return "raphy" ;

}

 

Thanks for your help.

be sure Tools is in the classpath: I suggest you to put it in the same directory as your report, or in the classes directory of iReport.

In this second case you risk to have to restart iReport each time you modify the class in order to force the use of the new one.

Hello,

I have my tools class as follows:

 

 

public class Tools

{

public static final String Name = "Raphy" ;

 

public static final String getName ()

{

return Name ;

}

}

 

Code:

public class Tools
{
  public static final String Name = "Raphy" ;
  
  public static final String getName ()
  {
    return Name ;
  }
}

 

When I set the textfield expression for the textfield as "Tools.Name" and executing the report gave me the results "Raphy". This is correct.

 

But when I set the textfield expression for the same textfield as "Tools.getName()" and when executing the report I got the error message as follows:

java.lang.NoClassDefFoundError:Âtest/Tools

 

The tools class and the report are in the same directory & and classpath set correctly.

 

Please help me

Best regards
