I have so far tried many times to make a program work at another location. Now I am totally lost for ideas. The program works at home but when I try it in a networked computer everything fails. I do not know why. I would be grateful if someone would look at my code and test it. Please reply to me here so that I could perhaps send the code. I would be eternally grateful. Thank you in advance. Here is the error, which I get only at the deployment location: Error: 500 Location: /myJSPs/jsp/portal-project/processviewfiles_dir.jsp Internal Servlet Error: javax.servlet.ServletException at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:460) at jsp.portal_0002dproject.processviewfiles_dir_4._jspService(processviewfiles_dir_4.java:163) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.tomcat.facade.ServletHandler.doService(ServletHandler.java:574) at org.apache.tomcat.core.Handler.invoke(Handler.java:322) at org.apache.tomcat.core.Handler.service(Handler.java:235) at org.apache.tomcat.facade.ServletHandler.service(ServletHandler.java:485) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:917) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:833) at org.apache.tomcat.modules.server.Http10Interceptor.processConnection(Http10Interceptor.java:176) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:494) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516) at java.lang.Thread.run(Thread.java:536) Root cause: java.lang.NullPointerException at jsp.portal_0002dproject.processviewfiles_dir_4._jspService(processviewfiles_dir_4.java:133) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.tomcat.facade.ServletHandler.doService(ServletHandler.java:574) at org.apache.tomcat.core.Handler.invoke(Handler.java:322) at org.apache.tomcat.core.Handler.service(Handler.java:235) at org.apache.tomcat.facade.ServletHandler.service(ServletHandler.java:485) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:917) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:833) at org.apache.tomcat.modules.server.Http10Interceptor.processConnection(Http10Interceptor.java:176) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:494) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516) at java.lang.Thread.run(Thread.java:536)
