-write seqfiles to hdfs from a java app without "hadoop jar" command

Hey there, I need to write seqfiles to an hdfs cluster using a normal java
app but can't use "hadoop jar".
I have access to the installation of a hadoop node.
I've reached the goal launching my app with java -jar and manually changing
de configuration in the code:
Configuration hadoopConf = new Configuration();
sfw = SequenceFile.createWriter(FileSystem.get(hadoopConf), hadoopConf,
** /opt/hadoop/install/conf/core-site.xml and
/opt/hadoop/install/conf/hdfs-site.xml are the conf files of the cluster.
This works but I would like to know if there's a more elegant way to do
that. Specifying hadoop env vars to the java classpath or something like
Thanks in advance.
