Hi,
the problem is the security-policy of the container I use for my
web-application. In this case it's the 'Sun Java System Application
Server Platform Edition 8.1'. As Thomas Down suggested, the Server
prohibits the creation of ClassLoaders, however they are needed by BioJava.
So I tried to customise the Server-configuration 'server.policy'-file by
adding a new line. Here is the code fraction:
grant {
permission java.lang.RuntimePermission "loadLibrary.*";
...
...
//new line:
permission java.lang.RuntimePermission "createClassLoader";
};
As some ClassLoader seems to have permission now, I think this was the
right starting point - and also the exception thrown changed. It's the
following:
org.biojava.bio.BioError: Unable to initialize DNATools

DNATools.java calls the following line in AlphabetManager.java:
InputStream alphabetStream =
ClassTools.getClassLoader(AlphabetManager.class).getResourceAsStream("org/biojava/bio/symbol/AlphabetManager.xml");
So I suppose that the change in the Server-Configuration-file is not
'globally enough' to affect all custom ClassLoader-calls.
Maybe someone has experienced something similar or knows something about
this specific Server?
Thanks,
Felix
