• RMI applet is making requests on random ports and blocked consequently

  - by Dan

  /// I have set up RMI system successfully on local ubuntu srver. Registry port 1099 and remote object export on 1100(fixed by calling super(1100)) Now I am trying to make it work on Ubuntu over internet with a public IP. I could bind service properly with public ip.But the client applet is trying to connect to ubuntu server at random ports. Below is the error thrown by client applet: // Exception network: Connecting public-ip:1100 with proxy=DIRECT network: Connecting public-ip/cgi-bin/java-rmi.cgi?forward=1099 with proxy=DIRECT network: Connecting public-ip:3733 with proxy=DIRECT network: Connecting public-ip:3721 with proxy=DIRECT // java.rmi.ConnectException: Connection refused to host: public-ip; nested exception is: java.net.ConnectException: Connection refused: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source)Source) at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source) ... // // I have only 2 ports open on server, i.e., 1099(registry) and 1100(export).

  I am in charge of a computer network in a small company (20..30 computers). Recently the need arose to control what kinds of programs our company is using i.e. to collect information that is available when one opens "Add or Remove Programs" in Windows.

• xerces-c: Xml parsing multiple files

  - by user459811

  I'm atempting to learn xerces-c and was following this tutorial online. http://www.yolinux.com/TUTORIALS/XML-Xerces-C.html I was able to get the tutorial to compile and run through a memory checker (valgrind) with no problems however when I made alterations to the program slightly, the memory checker returned some potential leak bytes. I only added a few extra lines to main to allow the program to read two files instead of one. int main() { string configFile="sample.xml"; // stat file. Get ambigious segfault otherwise. GetConfig appConfig; appConfig.readConfigFile(configFile); cout << "Application option A=" << appConfig.getOptionA() << endl; cout << "Application option B=" << appConfig.getOptionB() << endl; // Added code configFile = "sample1.xml"; appConfig.readConfigFile(configFile); cout << "Application option A=" << appConfig.getOptionA() << endl; cout << "Application option B=" << appConfig.getOptionB() << endl; return 0; } I was wondering why is it when I added the extra lines of code to read in another xml file, it would result in the following output? ==776== Using Valgrind-3.6.0 and LibVEX; rerun with -h for copyright info ==776== Command: ./a.out ==776== Application option A=10 Application option B=24 Application option A=30 Application option B=40 ==776== ==776== HEAP SUMMARY: ==776== in use at exit: 6 bytes in 2 blocks ==776== total heap usage: 4,031 allocs, 4,029 frees, 1,092,045 bytes allocated ==776== ==776== 3 bytes in 1 blocks are definitely lost in loss record 1 of 2 ==776== at 0x4C28B8C: operator new(unsigned long) (vg_replace_malloc.c:261) ==776== by 0x5225E9B: xercesc_3_1::MemoryManagerImpl::allocate(unsigned long) (MemoryManagerImpl.cpp:40) ==776== by 0x53006C8: xercesc_3_1::IconvGNULCPTranscoder::transcode(unsigned short const*, xercesc_3_1::MemoryManager*) (IconvGNUTransService.cpp:751) ==776== by 0x4038E7: GetConfig::readConfigFile(std::string&) (in /home/bonniehan/workspace/test/a.out) ==776== by 0x403B13: main (in /home/bonniehan/workspace/test/a.out) ==776== ==776== 3 bytes in 1 blocks are definitely lost in loss record 2 of 2 ==776== at 0x4C28B8C: operator new(unsigned long) (vg_replace_malloc.c:261) ==776== by 0x5225E9B: xercesc_3_1::MemoryManagerImpl::allocate(unsigned long) (MemoryManagerImpl.cpp:40) ==776== by 0x53006C8: xercesc_3_1::IconvGNULCPTranscoder::transcode(unsigned short const*, xercesc_3_1::MemoryManager*) (IconvGNUTransService.cpp:751) ==776== by 0x40393F: GetConfig::readConfigFile(std::string&) (in /home/bonniehan/workspace/test/a.out) ==776== by 0x403B13: main (in /home/bonniehan/workspace/test/a.out) ==776== ==776== LEAK SUMMARY: ==776== definitely lost: 6 bytes in 2 blocks ==776== indirectly lost: 0 bytes in 0 blocks ==776== possibly lost: 0 bytes in 0 blocks ==776== still reachable: 0 bytes in 0 blocks ==776== suppressed: 0 bytes in 0 blocks ==776== ==776== For counts of detected and suppressed errors, rerun with: -v ==776== ERROR SUMMARY: 2 errors from 2 contexts (suppressed: 2 from 2)

• Set item.selected in ASP.NET Menu Control

  - by BillB

  ASP.NET newbie here. When on a page I'd like to set the corresponding menu item to selected. My approach is this: On Home.aspx.cs: Menu menu = (Menu)Master.FindControl("Menu1"); if (menu.Items.Count > 0) { menu.FindItem("Home").Selected = true; } Trouble is, menu.item.count == 0. My menu is bound to a sitemap, if that matters. Thanks, Bill

• Redirect everything to index.php

  - by pixel

  I'm trying to do clean urls by exploding $_SERVER['REQUEST_URI'] and then switching between the results. However, once a user goes outside index.php, I'm assuming I need to redirect them back to index.php in order to process the URL they want to reach. How can I accomplish this? So for instance, user goes to www.domain.com/home/johndoe/... i'd like the index.php (domain.com/index.php) to be hit so that it can process the /home/johndoe/ via request_uri.
