"Migrating Applications from Tomcat 6 to Jboss AS 5.1" To view the discussion, visit: http://community.jboss.org/message/628617#628617 -------------------------------------------------------------- Hi, I have been assigned the task of migrating some applications that have been successfully running in Tomcat 6 to run inside the Jboss AS 5.1 container. I have had some success but I am not sure if I am going about it in the right way. The first challenge was with the classloaders which I was able to solve using the jboss-classloading.xml file in my application's war file under the WEB_INF dir. The contents of this file is discussed in the article by Joel Tosi(4/4/2011) entitled "Classloaders and You" which I have attached. The next challenge has been updating the tag library definitions. I keep running into errors like this: ERROR [ https://clairmail.jira.com/wiki/display/REG/cmmobile cmmobile] Servlet.service() for servlet cmmobile threw exception org.apache.jasper.JasperException: The absolute uri: http://tiles.apache.org/tags-tiles http://tiles.apache.org/tags-tiles cannot be resolved in either web.xml or the jar files deployed with this application. I was albe to resolve this for the jstl libs by includign this in my web.xml file: <taglib> <taglib-uri> http://java.sun.com/jstl/core http://java.sun.com/jstl/core</taglib-uri> <taglib-location>/WEB-INF/tld/c.tld</taglib-location> </taglib> and by downloading a c.tld file. None of this was neccessary for the the application to run under Tomcat 6. I am now running into the error described above. I manually changed web.xml to refrerence http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd where in the previous Tomcat version it was pointing to http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd. Similarly I manually changed the references in the tld files to " http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee web-jsptaglibrary_2_1.xsd from " http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd. Jboss seemed to complain about any references to j2ee. So that leads me to my question of should I have to be manually edittting these references? How can I resolve the above issue? All neccessary .jar files are present in the WEB-INF/lib dir however Jboss seems to ignore them in some cases. Any help in moving this forward would be greatly appreciated.
