    Hi everyone,

    i'm experiencing deployment problems dealing with classloading issues. Tomcat can't seem to detect my jar file:Servlet-api.jar inisde common/lib folder. This is the following error message:

  2. its not Tomcat Problem[ Go to top ]

    hi
    Its not Tomcat problem.if the Servlet-api.jar is not there then tomcat will not start as per my knowledge.
    This problem may be while deplying the webservice you will be getting this problem.

    1)check the All jar Files in your Context.


    Thank you
  3. Servlet-api.jar is present[ Go to top ]

    hi narayana,

    thanks for replying. the thing is this jar file is present and was placed in common/lib folder. so what do you think is the problem? really can't figure out.
  4. problem with web. xml[ Go to top ]

    check these files web.xml in WEB-INF and server.xml in config folder.
  5. I am also getting same exception and i am not able to use Axis webservice API.

    We are trying to insert the AXIS libraries into an existing web application. the axis web application (which comes with the Axis api) is working fine, where as when we try to customize Axis API to our web application its not working.

    Please advice.

    here is my exception log.

  6. Check the Class Loading Order[ Go to top ]

    You should check the class loading order and avoid any duplicate jar files, for example if the jboss common/lib has a utility jar like log4j.jar or the serlet api servlet-api.jar, you should avoid a repeat of similar jar file in your web-app (therefore remove duplicates from lower in the order) JBoss class load ordering is as follows (as given at http://www.jboss.org): Bootstrap | System | Common / \ Webapp1 Webapp2 ... Let only those libraries be there in your web-app that are specific to that web-app. This should fix the problem - if it still persists pls post the details again in the forum. Cheers, Rommel Sharma.
  7. Please let me know what you did to fix this issue. We are having this same problem.
