Precompiled JSP and Servlets on a Weblogic server (UNIX)

Question

We have a web application hosted on this webLogic server on a UNIX machine. Its primarily a JSP/Servlet based app. Whenever we do a modification/enhancemment to any one of those JSps or servlets, I precompile them on my local and deploy them on the UNIX system. For example, if there is a file called GetIdServlet.class, we usually rename the existing file to say GetIdServlet.class1 and then put in the new file as GetIdServlet.class. This is just to be able to revert back to the original file in case they are needed. However, I notice very strange behaviour. The application loses some functionality whenever we stop and start the server. The functionality may be back on the next or a few restarts after that. For example, a submit button that is supposed to direct it to the next page just stops working. It may start working after a few restart.

However on my local(Eclipse + webLogic) there is absolutely no issue. Everything works fine. Any ideas on what's going wrong?

Answer 1

You are using Unix Environment and i assume that the local desk setup used is windows OS or MAC. thus, when you copy the class files you are using some tool like WinSCP.

in case so, then please set the copy settings of such tool to use binary method of copying the files.

Example in WinSCP. go to Options->Preferences->Select Transfer in the Side Menu->under the Transfer Mode section, Select Binary option as the Transfer Mode. This will ensure that the binary replica is created on the Unix environment and that no data is lost in the transfer.
