Re: [Orekit Users] Help with ZipJarCrawler

Hi all,


Hi Carlos,


I'm having problems with the ZipJarCrawler data provider. I have the
following code:

DataProvidersManager.getInstance().clearProviders();
DataProvidersManager.getInstance().addProvider(new
DirectoryCrawler(myDirectory));

where myDirectory is a File object to my data folder, and the program works
perfectly fine. I now insert my data folder into the project JAR file and
replace those two lines with:

DataProvidersManager.getInstance().clearProviders();
DataProvidersManager.getInstance().addProvider(new ZipJarCrawler(myJar));

where myJar is a File object with the path to the JAR file. In this case
the program throws an IO exception with the message "Stream closed", which
is captured by an Orekit exception with the following stack trace:

org.orekit.data.ZipJarCrawler.feed(ZipJarCrawler.java:167)
org.orekit.data.DataProvidersManager.feed(DataProvidersManager.java:332)
org.orekit.frames.RapidDataAndPredictionXMLLoader.fillHistory1980(RapidDataAndPredictionXMLLoader.java:110)
org.orekit.frames.FramesFactory.getEOP1980History(FramesFactory.java:284)
org.orekit.frames.GTODProvider.<init>(GTODProvider.java:72)
org.orekit.frames.FramesFactory.getGTOD(FramesFactory.java:916)
and my project files from here on.

The data files are definitely in the JAR file, under a subdirectory called
data/orekit. Since the documentation says that the search is recursive the
data provider should be able to find the data files. I'm using the Orekit
6.0 release. What am I doing wrong?
Do you also have the stacktrace for the initial IOExcetion -it should appear after a "caused by ..." line. What I would like to know is if the exception was thrown while executing line 147 of ZipJarCrawler (i.e. when opening the jar itself), or at some deeper level from the list of recursuive calls starting at line 156 of ZipJarCrawler (i.e. when parsing the jar and reading the contained files). Also did you check the read access properties of the jar file? 

best regards,
Luc



Best regards,
Carlos.
