GWT external jars on client side

Is it possible to use external jars on the client side? For example
I'm trying to create a project that call BIRT jars on the client side,
but I get the typical error: Unable to find 'org/eclipse/birt/report/
engine/api/iReportEngine.gwt.xml' on your classpath; could be a typo,
or maybe you forgot to include a classpath entry for source? Since the
iReportEngine doesn't have a .gwt.xml, I figure from what I've read is
that i won't be able to use it on the client side. Is my only
workaround to put all the BIRT code on the client side?
