Question

I am trying to implement Office an PDF conversion system based on LibreOffice 4.0 and always get the ErrorCodeIOException(tried the file formats doc,docx,txt), my stacktrace is as follows:

com.sun.star.task.ErrorCodeIOException:

}
}

the exeption is generated in the line that says: 

xStorable.storeAsURL(sStoreUrl, propertyValues);

the code is based of the original examples of the libreofice api:

http://api.libreoffice.org/examples/java/DocumentHandling/DocumentConverter.java

thanks in advance if you can help

Was it helpful?

Solution

changing the line 

 xStorable.storeAsURL(sStoreUrl, propertyValues);

to 

 xStorable.storeToURL(sStoreUrl, propertyValues);

corrected the problem
