Bug#807928: [plantuml] plantuml does not render to PDF

[Daniel Hornung]

Package: plantuml
Version: 8024-2
Severity: normal

--- Please enter the report below this line. ---

When trying to render to pdf (svg and png work fine), these are the Java
exceptions:

$ plantuml -tpdf test_uml.pu

org.apache.batik.apps.rasterizer.SVGConverter exists though in
/usr/share/java/batik-rasterizer.jar, which exists here and is provided by
libbatik-java (maybe this should become a dependency, by the way?). So maybe
this should be added to the class path at compile time? Sorry, I don't know
enough about java compilation for proper suggestions.

Hi,

it's the same whether I explicitly set the classpath to the local location
(shouldn't that be found automatically?) or a folder with the jars from your
site.

System jars:

$ java -jar /usr/share/plantuml/plantuml.jar -cp /usr/share/java/ -tpdf
data_model.plant_uml.pu
Exception in thread "main" java.lang.UnsupportedOperationException: PDF

Local jars, from the zip file:

$ java -jar /usr/share/plantuml/plantuml.jar -cp ./jars/ -tpdf
data_model.plant_uml.pu

The problem that the library can not be found goes away in both cases, but the
second exception remains.

I found one way to fix this manually:

In the plantuml.jar, add to the manifest (META-INF/MANIFEST.MF) the following
line:

Class-Path: /usr/share/java/batik-rasterizer.jar /usr/share/java/batik-
transcoder.jar /usr/share/java/fop.jar

With this line, export to pdf works for me without specifying the classpath
manually.

For the Debian build script, this should probably be included, either manually
or somewhere in the Ant building specifications.

Additionally, maybe the packages providing these jars should be added as
recommended dependencies:

libfop-java (provides /usr/share/java/fop.jar)
libbatik-java (provides batik-rasterizer.jar and batik-transcoder.jar, but is
already a dependency for libfop-java, so the former should be enough)

Daniel, thanks for your investigations.

I will have a look at this when I find time. This certainly is a thing
we should have enabled in PlantUML in Debian.
