Help other projects upgrade from iText 2.x to OpenPDF

[andreasrosdal]

This issue is about helping other open source projects migrating from iText 2.x to OpenPDF, so they can continue using the maintained LGPL/MPL version.

Atlassian Confluence: https://jira.atlassian.com/browse/CONFSERVER-55407

There are other projects here as well: https://mvnrepository.com/artifact/com.itextpdf/itextpdf

flyingsaucer project already has openpdf profile https://mvnrepository.com/artifact/org.xhtmlrenderer/flying-saucer-pdf-openpdf

https://github.com/nuxeo/nuxeo-signature already using openpdf

1. Binary is available in maven central: https://search.maven.org/search?q=g:com.github.librepdf%20AND%20a:openpdf&core=gav

2. Your 2nd question I don't understand - do you want to build your own binary? This is possible just download it via git and build it using the maven.

3. Just replace the jar and have a look where you get errors...

Hi, same problem with Eclipse here. I don't use Maven, I want to build it myself, but I don't get the main project imported. I.e., using Eclipse (2019-09), I try to import the project from the sources path, but only the pdf-swing and pdf-toolbox are imported properly, and Eclipse projects are created for them, but for openpdf not. An empty nuild configuration is created only. What is the reason?

[srbala]

you have to import project as existing maven project and select pom.xml in root folder

[srbala]

It's easier to get prebuilt jar from maven repository, unless you are planning on work on any issues. Master branch points upto date development. If you need stable sources, use release versions https://github.com/LibrePDF/OpenPDF/archive/1.3.11.zip for 1.3.11 release. Prior versions available at https://github.com/LibrePDF/OpenPDF/releases

It's simply strange. What is openpdf-parent? Eclipse it's not that friendly in referring projects. On one hand, importing as Maven, although seems successful, doesn't work for pdf-swing, pdf-toolbox, because claims those can't find openpdf build through Maven. I would have expected to be able to refer openpdf from the local build... Anyway, I probably don't need them, so removing them or ignoring the errors, would make my test project build. Here comes the total disappointment. Eclipse is able to build my test project only if I refer the openpdf project as module. But can't run it, it says it can't find openpdf module. I have worked with Eclipse years ago, now I feel like a total newbie. Or Eclipse is still unfinished here... and can't add the needed runtime params to vm?

[msdobrescu]

And to clarify why I have did like this: I need to debug openpdf just to start understanding it and know it better.

[srbala]

Looks like you are not familiar with maven and how to compile and build. Please google up, you may find some material. It might takes tedious step using debug in Maven; you may have to use the sources to import into regular java project and set the dependency manually.

This thread OR project issues is not meant to be how-to

[msdobrescu]

Indeed, but Maven is not my choice at all, I should not intall Maven related plugins just to disable/remove it from the project. For me, it's just like shooting flies with a canon, while I need just to build a plain java library.

Hi, I chose Maven, in the end, even in Eclipse. The reason is Eclipse is not that clever at importing OpenPDF. It can't properly import OpenPDF because the parent project is called "OpenPDF" and contains the core project, called "openpdf" , that name being in conflict (regardless the casing). So, it throws an error and import stops. At least under Windows. This might be one thing to take into account. As Maven project is plain simple, even in Eclipse.

Making xdoc-report(https://github.com/opensagres/xdocreport) compatible with OpenPDF with #333

@codecracker2014 Going backwards is not a good option, might be good to update xdoc-report

@andreasrosdal, @srbala there are around 160 open source projects listed on maven (https://mvnrepository.com/artifact/com.lowagie/itext) which are using itext 2, if we can keep backward compatibility it would be really easy for them to migrate. Regarding https://github.com/LibrePDF/OpenPDF/pull/333#issuecomment-580730527: Pull request for backward compatibility have been already merged with #210. Java 8 generics is not done yet fully, i would suggest to do it in future versions.

I also tried to do changes in xdoc-reports instead of OpenPDF, there are lot of changes needs to be done as compared to OpenPDF change. Also that will make OpenPDF compatible to just xdoc-report, lot of other projects will still be remaining.
