i noticed this message while catching up on some mail backlog ... i don't know anything baout Oracle's app server, but some creative googling for the error message you cited suggests to me that "Failed in uploading archive. Invalid archive file:" is a common error message preamble anytime Oracle's app server hasa problem starting up a war .... the "Start of root element expected" part of the message might be the message from an exception from Solr relating to a config file -- or it might relate to anoracle specific config file ... i have no idea.
here's a similar error someone incountered where a very similar message refered to a problem with the "oracle-webservices.xml" file .... perhaps htat file is not welformed on your system... http://forums.oracle.com/forums/thread.jspa?messageID=1800964 ...i'm not sure that anyone in the solr community can provide you much help without some more detailed info about what kinds of errors you re getting from the actual messages logged by Solr. : I've tried to deploy the solr war file in Oracle 10G, but keep getting : the following error: : : " Failed in uploading archive. Invalid archive file: Start of root : element expected." -Hoss
