JAXB custom conversion using @XmlJavaTypeAdapter

To provide your own conversion implementation of a JAXB property, annotate the property in your JAXB class with javax.xml.bind.annotation.adapters.@XmlJavaTypeAdapter:

    @XmlJavaTypeAdapter(MyAdapter.class)
    public void setFrom(LocalDate from) {
        this.from = from;
    }
 
Then write your Adapter marshalling your LocalDate attribute to an XML value String and unmarshalling it:

    public class MyDateAdapter extends XmlAdapter<String, LocalDate> {
    public LocalDate unmarshal(String myString) throws Exception {
      return LocalDate.parse(myString);
    }

    public String marshal(LocalDate myDate) throws Exception {
      return myDate.toString();
    }
  }

Glassfish console log timestamps

By default glassfish does not add timestamps to console logging messages and that allways leaves me wondering wether I'm looking at an old message or a new one.
To add timestamps edit $GLASSFISH_INSTALL/glassfish/domains/domain1/config/logging.properties
Replace domain1 with the domain your domainin the above,  if you are not using the default domain.
change:
java.util.logging.ConsoleHandler.formatter=com.sun.enterprise.server.logging.UniformLogFormatter
to:
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

The default format is fine for me, but you can customize the format using:
java.util.logging.SimpleFormatter.format="your %format string"

The javadoc contains some format string examples.
Then (re)start the server.

Java EE component versions overview (updated)

The table below lists the components in latest versions of the Java Enterprise Edition.
Many of the Java EE projects live on github.
After Java EE8, Java EE is moving to the EE4J project (Eclipse Enterprise For Java) aka Jakarta.

• I put the most important changes in red.
• Components with a [version number] between brackets are  proposed for removal in a future release.
• An x indicates a technology is removed from the specification
• JSR's are shown as hyperlinked numbers.
• SE indicates that an API was moved to the standard edition 
• eventually followed with the version number
• Java SE version history is in a separate post 
• These API's will be removed from Java SE again with Java 11
• Web technologies are in a separate post
• EJB history is in a separate post
• I added some application servers at the bottom of the table.

Securely opening tabs to other sites from your webpage

You can use a link on your webpage to open a page from another site in another tab, using

<a ref="https://othersite/otherpage.html" target="_blank">
  to  other page
</a>

Your browser typically opens the other page in a new tab, but this page retains a relation with your webpage and can do some priviliged actions like redirecting the tab of your webpage to another URL.
To prevent this, break the opener and referer links the foreign page has to your webpage by using

<a ref="https://othersite/otherpage.html" target="_blank" rel ="noopener noreferer"> 
   to  other page 
</a>
