Before deploying latest apex images in web logic server, you must create a Web archive (WAR) file to contain the Oracle APEX image files.
Using the Java Archive (jar) command, enter the following command to create a Web archive file named images.war:
jar –cvf0 <temp directory>images.war –C <apex directory>images .
■ <temp directory> is the directory location of the unzipped Oracle Application
Express Listener file.
■ <apex directory> is the directory location of Oracle Application Express.
Thanks to Oracle
