    Error Loading Jsp Page

    in Questions

    Posted

    Sorry for my late answering, but I was out.

     

    The problems happens on loading almost every page of the site. The first one looks for a session variable: if it is not present, the output is redirected on a login page; otherwise (i.e., the user is just logged in) the index.jsp page is shown, with the complete menu.

     

    I don't think this can overload by itself the server; could perhaps the concurrency with other requests of other applications produce this error?

     

    Thanks

     

    Error Loading Jsp Page

    in Questions

    Posted

    Hi, I'm softlab on Johnny, my site is infopar.heliohost.org/webCat. I have a problem when I try to load the site: very often I get this message:

     

     

    Proxy Error

     

    The proxy server received an invalid response from an upstream server.

    The proxy server could not handle the request GET /webCat/.

     

    Reason: Error reading from remote server

     

     

    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

     

     

    If I try to reload the site, after several attempts finally the site loads; but, every button I click on the site, the same problem happens, and only after several other attemps I succeed. And so on.

     

    In the error log in my cPanel there is no more information, only a reference to a 404 error as said in the error message.

     

    Can you help me?

     

    Thank you

    With catechesi.war there is some other problems, because it should show a login page with a struts form, but shows only the header of the page and nothing else.

     

    I would like to make a try with the previous version of the application, without struts.

     

    Please, deploy webCat.war.

     

    Thanks

    [Solved] Error Starting Struts Application

    About the error you said is thrown at the startup of my catechesi application:

     

    FAIL - Application at context path /infopar_catechesi could not be started

    FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [standardEngine[Catalina].StandardHost[localhost].StandardContext[/infopar_catechesi]]

     

    Is there anything more in some tomcat logs (i.e. catalina.log) that shows more information about the error?

     

    Thanks

    I googled a little, finding that the problem could be generated by an incorrect servlet mapping. I made some modifications to struts-config to remove references to the "logic:notPresent" instructions I deleted in the last deploy.

     

    Please, deploy catechesi.war, new version.

    Thanks

    Problem With Struts

    in Questions

    I can't understand where is the problem.

     

    When a couple of days ago I requested a deploy, Krydos replied "I've tried deploying this servlet for you three of four times now over the last couple days. I have no idea what the problem is but tomcat just hangs trying to load it. It can just sit there for an hour trying to deploy it and it never works". The change I'd done was to remove the "logic:notPresent" tag, substituting it with a forward conditioned by a java "if" in index.jsp, testing the presence in the session of a variable; I can't imagine that this change can make Tomcat crash. Do you see anything in the logs that can help in understanding where the problem could be?

     

    Thank you

    I retried now, but same error.

     

    The stack says "The full stack trace of the root cause is available in the Apache Tomcat/7.0.32 logs". Could you see anything related to it now (11/06/2013 12:01 GMT+1)?

     

    Thank you

    I tried to remove a "logic:notPresent" struts tag, and now it does not get an error (now it just seems not to load the css file).

     

    I just wonder which could be the problem with that struts tag... I'll try something else.
