Our product intends to save you a significant amount of your time, and spare you the difficulties of a manual process. As explained in my previous post “How to create PDF files from XML with Apache-FOP”, XSL-FO and Apache-FOP provide a free and standard way to create PDF files in a language independent manner.
there are a number of disadvantages with that approach, e.g.:
- you have to learn XSL-FO (and therefore also XPath and XSL).
- even if you know XSL-FO you do not want to be writing FO templates using a text editor.
- there is some logic that cannot be easily defined using
XSL-FO. For example, grouping of data requires you to use the so
method , which isn't straightforward to understand.
In order to overcome these drawbacks, at J4L Components we have developed J4L FO Designer. The designer is a Visual (WYSIWYG) editor that will generate XSL-FO files for you. This makes the start into the XSL-FO world very easy, and it is also a useful tool for experienced developers since you can create and test XSL-FO files very quickly.
Este procedimiento sirve para cuando tenemos una cuenta de Gmail y queremos usar Gmail como servicio para gestionar otras cuentas que no son de Google, sin tener que decir a nuestros contactos que hemos cambiado de correo. Es decir para nuestros contactos no cambia nada: siguen usando nuestra dirección de correo que conocen. Para nosotros cambia que usamos el servicio de Gmail para gestionar este correo y, aunque sigue activo, ya no necesitamos usar el servicio del proveedor original.
Repitiendo este procedimiento se pueden integrar varias cuentas externas en una ÚNICA cuenta gratuita de Gmail. También se puede repetir usando varias cuentas independientes de Gmail gratuito. Si se desea un servicio unificado para la gestión de diversas cuentas de una organización con Gmail, deberá contratarse el servicio de pago "Google Apps".

Nowadays, XML is the native format of many applications, Oracle APEX for example, partly bases its reporting systen on XML. Middleware as Oracle BPEL, SAP PI, IBM Websphere and of course many Web services are also XML based. XML is also being used as exchange format in business to business transactions, for example for e-Invoicing. In these and many other environments there is often the need to create PDF files from XML.
In the past PDF files would be created using proprietary reporting tools that would use a database as data source. Additionally these tools are programming language specific. Later on the XSL-FO standard allowed for a better way to do it in many cases.
What is new about XSL-FO?
- it is programming language neutral.
- it is a standard so you are not tied to a vendor.
- it uses XML as data source.
Many free/open source products have a license model that puts strong restrictions on the way you may use the software. Not surprisingly there are software companies that do not allow the use in their code any open source software other than Apache Foundation one. So if you use Apache you know you are on the safe side.
