Alternative to latex / a way to typeset good looking documents from Java to PDF

I'm working on application in Java that will maintain database of song lyrics in plain text and print out some songbooks/chordbooks(that is create PDF file from selected songs). I was planing that the Java application will generate source code for pdflatex and after compiling this source user will get PDF file.

Lately I've run into a lot of problems because of latex limitation: fixed memory size (some pictures will also be drawn to PDF) - error when exceeded, no way to query end of line or and of page dynamically, it's very hard to override latex placement algorithm in a complex way,... see also some my other questions regarding latex. I come to conclusion that latex is not good option for automated PDF generation.

So I need replacement. I need to be able to typeset:

• Chords over lyrics when the lyrics are in variable char 开发者_JAVA百科width so I need to be able to measure text width
• Chord diagrams that means I'll have to draw quite complex pictures
• Each song on separate double page
• Different fonts etc.

Thanks for all answers

Here are some PDF open source APIs http://java-source.net/open-source/pdf-libraries

This has been asked many time, You might want to look at this post

IText is a free library which offers lots of capabilities for creating PDFs programmatically.

Rather than try to manage/calculate the complexities of the desired layout, you could try Docmosis. It will let you layout a document as a template using doc or odt formats. This means if you could make a doc or odt look like you want, you can turn it into a template and get Docmosis to render it as a PDF. Text and images can be placed inside or outside tables which makes layout fairly easy to manage.

ConTeXt is another TeX system, but it is easier to control the layout than with LaTeX. For drawing you could use PGF/TikZ or MetaPost. Support for both is available in ConTeXt. With ConTeXt's built in Lua scripting you could draw the chords automatically, assuming you have them stored in some sort of data structure.

why not just use lilypond with latex? it's meant for typesetting music.
