in_memory_json

[RobertPrediger]

I have a report definition with 'in_memory_json'.
After calling, I get this error:

error: Error creating class
portal-dev-0 (err): net.sf.jasperreports.engine.JRException: 
com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 middle byte 0x74

What can I do to avoid this behaviour?
If you need more info, tell me. ;)

Thanks

Hello Robert,

Seems data in your json has non utf-8 characters.

You should convert it manually to utf-8 or use iconv to do it, before you use it with node-jasper.

Hope it helps.

But this happens only, if I put a data: {} inside.

This is fine (but creating an empty pdf-file):

    var report  = jasper.pdf( {
        report:     repName,
        dataset:    data
    } );

This one is producing this error:

   var report  = jasper.pdf( {
        report:     repName,
        data:       {},
        dataset:    data
    } );

Now I have it.
You have problems with converting data to Java.

If you take your example and put a German umlaut inside (in utf-8 format, example "ä"), than you'll get this error.

How can ve avoid this?

Hi Robert, that's weird... could you give me a full example so I can run it
and see what's wrong?

Thanks.

Hi,

just simply add an "ä" in one of the strings in data in your example.
This should produce this error.

Thanks!

Best regards
Robert

Just use this:

[{ 
    name: 'Gonzalo',
    lastname: 'Vinasä'   // here is an umlaut
}, {
    name: 'Agustin',
    lastname: 'Moyano'
}]

Hi,

I think the problem continues when using ToJsonDataSource method, cause you changed just the processConn method but not toJsonDataSource method, which is using the old code and giving the same error with UTF-8.

I would really appreciate if you can change this. Really thanks in advance for the plugin !!! :)

BR.

Hi,

This works! (commented the old part and using the same as processConn)

I cannot pull the project in order to do a Pull Request because from my Git Client I just can pull organization projects... :( Sorry.

Thanks in advance !!
