CSV handling in Java

These past days i've been trying to load CSV files in Java. Used opencsv with some degree with success, however some fields were still misinterpreted .
Next an old friend by name of FasterXML/jackson came to the rescue, however i was still having some issues.
Last but not least on stackoverflow.com (where else) i came across https://simpleflatmapper.org/ and with something like:

CsvParser.separator(';')

   .mapTo(MyClass.class)

   .headers("my","headers","list")

   .iterator(new File(filepath));

I was up and running .

Note : If you find MalformedInputException check if your input is UTF-8 , more info here  http://biercoff.com/malformedinputexception-input-length-1-exception-solution-for-scala-and-java/

JAVAMAIL: Cleaning temporary files used as attachments

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

private static void cleanAttachments(MimeMessage message) { try { if (message.getContent() != null) { MimeMultipart multi = (MimeMultipart) message.getContent(); for (int j = 0; j < multi.getCount(); j++) { BodyPart bodyPart = multi.getBodyPart(j); if (bodyPart.getDataHandler().getDataSource() instanceof FileDataSource) { FileDataSource f = (FileDataSource) bodyPart.getDataHandler().getDataSource(); f.getFile().delete(); } } } } catch (MessagingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }

For when you use File.createTempFile  to support the attachments of a mail message and cannot use deleteOnExit because the JVM will not exit.

Something i saw myself needing.

All the best.

Quartz Scheduler

Thanks to who had the work of making my life easier :)

Struts 2 and TLD issues.

According to TLD or attribute directive in tag file, attribute value does not accept any expressions

I have been rather plagued by this error on the last few days when using Struts2 till. By chance i came across https://almeidamike.wordpress.com/2010/03/12/struts-solving-according-to-tld-or-attribute-directive-in-tag-file-attribute-value-does-not-accept-any-expressions/ .
So if you are having some difficulties accessing parameters of the request or other values be sure to enable debug as specified in https://struts.apache.org/docs/debugging-struts.html and find the correct path to your value.

Examples:
${someField} becomes %{#attr.someField}. Acessing request parameters would be for instance  %{#parameters.someField}.

Before delving into Odoo i would like to share a project that has saved my life a couple of times - signtester .
If you need to sign (re-sign) several jar files take a look at it :)
