Has any one implemented converting a XML message to a PDF using Message Broker? Is it possible.
I am trying to do a POC. Any inputs will be greatly appreciated |

Not out of the box.
Perhaps you can look for some free pdf converter packages.
Regards. |

Apparently not. Which means we'll all be looking forward to hearing how you get on.
(I think it sounds really interesting!).

It's entirely possible to do in pure ESQL, I'm sure. PDF is just text, or should be.
It would be an excessive amount of work however.
Using an existing PDF creation library, it should be "as easy as" use a JCN to
- map from the message broker logical tree into native Java data types
- use a PDF java library, perhaps the one pointed to here to construct a new PDF document or load a "template"
- insert the message data
- tell the PDF library to serialize the document into a bitstream
- insert the bitstream into the Java equivalent of OutputRoot.BLOB.BLOB
And then use normal message broker nodes to output the PDF document however you want. |

But to answer the OP's basic question you've not actually done this?
Which in no way diminishes the value of your suggestion as a possible method of doing it.

do you suggest implementing it in Message Broker?

Thanks for the Suggestion. I was thinking in the same line too.
Any IBM guys comment on this... can it be done? |

I think this is generally true, unless they contain embedded images for example. Just a thought and happy to be corrected. |

Well, PDF is a dialect of PostScript and PostScript should in theory consist only of plain text - in much the same way that an SMTP message should consist of plain text.
I believe PDF has some structures that allow for the embedding of binary content, in a vague analogy to a CDATA structure in an XML Document (except CDATA *does not* let you embed binary content). But I also believe it's better practice to embed it in a transcoded form like base64.
But it's been a long time since I've played with the state of the art of these things, so that could all be decades out of date. |
