[basex-talk] problem: accessing inner java class methods with bases java bindings

[Florian Eckey]

Hi,

I use basex java bindings in my project. It works fine but when I try to access 
inner java classes i cant find a way to get it work.
I will use the SimpleJavaMail libs and there is a class called 
“MailerRegularBuilder” which is an inner class of “MailerBuilder”, especially 
with the method “buildMailer()”.

Here is a sample snippet of the based java class source code:
public class MailerBuilder {

        ...


       private MailerBuilder() {

        }



        public static class MailerRegularBuilder extends 
MailerGenericBuilder<MailerRegularBuilder> {



        ...



               public Mailer buildMailer() {

                       return new Mailer(this);

                }



        ...



        }

}

In java I can easily access this method in the inner class with the following 
code (in red):


MailerRegularBuilder mailRegularBuilder = 
MailerBuilder.withSMTPServer("smtp.gmail.com", 465, "username1", "password1");

mailRegularBuilder = 
mailRegularBuilder.withProperty("mail.smtp.starttls.enable", "true");

mailRegularBuilder = 
mailRegularBuilder.withProperty("mail.smtp.socketFactory.class", 
"javax.net.ssl.SSLSocketFactory");



Mailer inhouseMailer = mailRegularBuilder.buildMailer();



inhouseMailer.sendMail(email);



That works fine (remember it is only a snipped).

With XQuery I always get a class not found exception or a unknown method 
exception with the following code:



declare namespace Email = "java:org.simplejavamail.email.Email";

declare namespace EmailBuilder = "java:org.simplejavamail.email.EmailBuilder";

declare namespace Mailer = "java:org.simplejavamail.mailer.Mailer";

declare namespace MailerBuilder = 
"java:org.simplejavamail.mailer.MailerBuilder";

declare namespace EmailPopulatingBuilder = 
"java:org.simplejavamail.email.EmailPopulatingBuilder";

declare namespace MailerRegularBuilder = 
"java:org.simplejavamail.mailer.MailerBuilder.MailerRegularBuilder";

declare namespace MailerGenericBuilder = 
"java:org.simplejavamail.mailer.MailerGenericBuilder";



declare variable $local:fromName := "Florian Eckey";

declare variable $local:fromEmailAdress := "a...@gmail.com";

declare variable $local:username := "username1"

declare variable $local:password := "password1";

declare variable $local:smtpServer := "smtp.gmail.com";

declare variable $local:smtpPort := 465;



declare function local:sendMail($toName, $toEmailAdress, $subject, $plainText, 
$attachementName, $attachement, $attachementType) {

  let $emailPopulatingBuilder := EmailBuilder:starting-blank()

  let $emailPopulatingBuilder := 
EmailPopulatingBuilder:from($emailPopulatingBuilder,$local:fromName, 
$local:fromEmailAdress)

  let $emailPopulatingBuilder := 
EmailPopulatingBuilder:to($emailPopulatingBuilder,$toName, $toEmailAdress)

  let $emailPopulatingBuilder := 
EmailPopulatingBuilder:withSubject($emailPopulatingBuilder,$subject)

  let $emailPopulatingBuilder := if($attachement) then 
EmailPopulatingBuilder:withAttachment($attachementName, $attachement, 
$attachementType) else $emailPopulatingBuilder

  let $emailPopulatingBuilder := 
EmailPopulatingBuilder:withPlainText($emailPopulatingBuilder,$plainText)



  let $email := EmailPopulatingBuilder:buildEmail($emailPopulatingBuilder)



  let $mailerRegularBuilder := MailerBuilder:withSMTPServer($local:smtpServer, 
xs:int($local:smtpPort), $local:username, $local:password)

  let $mailerRegularBuilder := 
MailerGenericBuilder:withProperty($mailerRegularBuilder,"mail.smtp.starttls.enable",
 "true")

  let $mailerRegularBuilder := 
MailerGenericBuilder:withProperty($mailerRegularBuilder,"mail.smtp.socketFactory.class",
 "javax.net.ssl.SSLSocketFactory")



  let $mailer := MailerRegularBuilder:buildMailer($mailerRegularBuilder)



  return (Mailer:sendMail($mailer,$email),"email send")

};



The red line will always throw the error: [XPST0017] Unknown class: 
org.simplejavamail.mailer.MailerBuilder.MailerRegularBuilder.

Beside: I copied all the used java libs into the lib folder of my basex 
instance. All other classes were found.

Does anyone have an idea how to access this inner class methods? Or is it not 
possible and I have to implement a custom java lib which masks the code in one 
static method?

Best regards,
Florian

PS: Sorry for the unhighlighted code, but it was just copied from the basex gui.
