  • using virtual machine like mySql server

    - by ffmm
    i'm developing a java program and i need a database. Now i'm using MAMP and it's pretty easy but i would have a virtual machine (ubuntu server) and i need to connect my java program with this virtual machine using vitualBox. the situation: I installed VirtualBox on my mac and I installed an ubuntu-server machine set "bridge adapter" in the network settings of VB I installed mysql on ubuntu-server and i created a simple database (all work well by ubuntu) doing ifconfig by ubuntu I get the ip: 192.168.1.217 so in the java program i made this function: public static Connection connect(String host, int port, String dbName, String user, String passwd) { Connection dbConnection = null; try { String dbString = null; Class.forName("com.mysql.jdbc.Driver").newInstance(); dbString = "jdbc:mysql://" + host + ":" + port + "/" + dbName; dbConnection = DriverManager.getConnection(dbString, user, passwd); } catch (Exception e) { System.err.println("Failed to connect with the DB"); e.printStackTrace(); } return dbConnection; } and in the main() i use: Connection con = connect(1, "192.168.1.217", 3306, "Ciao", "root", "cocacola"); 3306 was a default value. I don't know if is correct, it works on mamp, but…. how I can find the correct port that I have to use with VB? when I ran the program I get the catch excepion… what's wrong? ps: i have to install apache o something else?

  • Implement two functions with the same name but different, non-covariant return types due to multiple abstract base classes

    - by user1508167
    If I have two abstract classes defining a pure virtual function with the same name, but different, non-covariant return types, how can I derive from these and define an implementation for both their functions? #include <iostream> class ITestA { public: virtual ~ITestA() {}; virtual float test() =0; }; class ITestB { public: virtual ~ITestB() {}; virtual bool test() =0; }; class C : public ITestA, public ITestB { public: /* Somehow implement ITestA::test and ITestB::test */ }; int main() { ITestA *a = new C(); std::cout << a->test() << std::endl; // should print a float, like "3.14" ITestB *b = dynamic_cast<ITestB *>(a); if (b) { std::cout << b->test() << std::endl; // should print "1" or "0" } delete(a); return 0; } As long as I don't call C::test() directly there's nothing ambiguous, so I think that it should work somehow and I guess I just didn't find the right notation yet. Or is this impossible, if so: Why?

  • VM's, virtual networks and my home network.

    - by Jason Taylor
    I want to create a small lab of VM's to test out networking with. I have two PC's running VMWare and I need the VM's on these two PC's to be connected to their own LAN. I am planning on bridging the VM's into my home network. My home network and PC's are in the 192.168.0.0 range, but I want my VM's to be in 10.1.0.0. If I do it this way (Bridging the VM's on both hosts into the network) will the VM's be able to communicate? Will my home router freak out seeing two different subnets? Is there another, easier way to connect the virtual lan's on two vmware workstations together?

  • Android's EditText is hidden when the virtual keyboard is shown and a SurfaceView is involved

    - by Jan
    I have a simple user interface: an EditText should be located below a SurfaceView. I use a RelativeLayout to arrange these two views. Now, when I tap on the EditText to open the virtual keyboard the SurfaceView slides up but the EditText is hidden and does not show the typed string. To reproduce, use the following layout XML code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent"> <SurfaceView android:id="@+id/SurfaceView01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </SurfaceView> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" android:selectAllOnFocus="true" android:textStyle="normal" android:singleLine="true"> </EditText> </RelativeLayout> The main Activity class only needs to show the layout. When I start the program and tap the EditText, the virtual keyboard appears but the EditText field is gone. Maybe the RelativeLayout is causing the problems, but I don't know how to reproduce the same layout with another Layout class. Any suggestions are welcome, I really appreciate your help. Thanks. Edit: Here are two screenshots, one showing the EditText at the bottom without virtual keyboard, one with virtual keyboard but with no EditText. It is interesting to note that the SurfaceView and the EditText actually shift upward, the EditText just disappears. BTW this also happens to a button if it is next to the EditText. EditText below a SurfaceView (left); EditText is gone (right)

  • How does virtual inheritance solve the diamond problem?

    - by cambr
    class A { public: void eat(){ cout<<"A";} }; class B: virtual public A { public: void eat(){ cout<<"B";} }; class C: virtual public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I understand the diamond problem, and above piece of code does not have that problem. How exatly does virtual inheritance solve the problem? What I understand: When I say A *a = new D();, the compiler wants to know if an object of type D can be assigned to a pointer of type A, but it has two paths that it can follow, but cannot decide by itself. So, how does virtual inheritance resolve the issue (help compiler take the decision)?

  • question regarding templatization of virtual function

    - by jan
    Hi, I am new to this forum and sorry If I am repeating this question. I know that you cannot templatize the virtual function and I do understand the concept behind it. But I still need a way to get across some errors I am getting it. I am able to make my stuff work but it doesn't look to me. Here's the deal, I have class called System, #include "Vector.h" class System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const = 0; }; class UnresolvedSystem : public System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const { //do something } }; In Vector.h tenplate<typename T> class Vector { //some functions }; See now I want to templatize VectorToLocal in system.h to take just Vector, but I cannot do it as it is a virtual function. I want a work around. I know I can have VectorToLocal take Vector, Vector etc as arguments. But I do not want to do it. Any help would be really appreciated. Thanks in advance, Jan

  • IHttpModule not being applied to virtual directory

    - by arthurdent510
    I have a network folder that is mapped to my iis app as a virtual directory and I'm trying to do some authentication for files that are located there with an ihttpmodule. I've verified that the ihttpmodule is firing properly for anything else in my app, just not the files located in virtual directory. Most of what I've found is that the directory can't be listed as an application (which it isn't), and everything should work. The other solution that I found was to add the the module tag to the tag, but that didn't seem to help either. Everything that I've found talks about stopping this from happening. So my question is what could be set that is causing this to not work? Is there a certain execute permission that needs to be set? Any other iis settings that could cause this? It is an mvc app, and this is how my directory structure is laid out: server/app <- my application folder server/app/content/downloads <- downloads is the virtual directory Do I have to add the virtual directory directly under my app directory? Is that part of the problem? I don't have direct control of the server my code is running on, so testing things out is a bit of a pain... so I was looking for some more thoughts before starting to send emails off to my operations people. Thanks!

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.

  • Questions regarding detouring by modifying the virtual table

    - by Elliott Darfink
    I've been practicing detours using the same approach as Microsoft Detours (replace the first five bytes with a jmp and an address). More recently I've been reading about detouring by modifying the virtual table. I would appreciate if someone could shed some light on the subject by mentioning a few pros and cons with this method compared to the one previously mentioned! I'd also like to ask about patched vtables and objects on the stack. Consider the following situation: // Class definition struct Foo { virtual void Call(void) { std::cout << "FooCall\n"; } }; // If it's GCC, 'this' is passed as the first parameter void MyCall(Foo * object) { std::cout << "MyCall\n"; } // In some function Foo * foo = new Foo; // Allocated on the heap Foo foo2; // Created on the stack // Arguments: void ** vtable, uint offset, void * replacement PatchVTable(*reinterpret_cast<void***>(foo), 0, MyCall); // Call the methods foo->Call(); // Outputs: 'MyCall' foo2.Call(); // Outputs: 'FooCall' In this case foo->Call() would end up calling MyCall(Foo * object) whilst foo2.Call() call the original function (i.e Foo::Call(void) method). This is because the compiler will try to decide any virtual calls during compile time if possible (correct me if I'm wrong). Does that mean it does not matter if you patch the virtual table or not, as long as you use objects on the stack (not heap allocated)?

  • IIS redirect url for virtual directory

    - by Jouni
    Hello, How i can set redirect url for virtual directory in iis 7.0.I have installed lates url rewrite module 2. ? I could explain my problem with exsample. I have website on my iis 7.0 server: www.mysite.com I desided to create virtual directory sales under my site which is pointing to website root directory.Now I need create redirect url for the vdir. The vdir is pointing same virtual root directory as my site root is The big idea is that i can write on browser www.mysite/sales and i will automaticly redirect to url www.mysite.com?productid=200. I tried to make redirect with rewite url for vdir(not website), but I always get this error message : cannot add duplicate colletion entry of type 'rule' with unique key key attribute 'name' set to "test".This happens when i am pointing for virtual vdir and try to add rule. I can add rules to website level,but rules doesn work. I mean url www.mysite/sales gives me follwing error. I know that key is unique I checked it from web.config. This kind of feature was really easy use in IIS 6.0, just point vdir with your mouse and set properties--a redirect to url. Please some one explain what is right way to do it in IIS 7.0

  • How to rearm Microsoft Office in 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1)

    - by John Assymptoth
    I'm doing some tests in a 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1). However, after a few days (maybe ~180), Office is now saying that it needs to be activated. I've tried rearming with OSPPREARM.EXE, but I get the following error: "The security processor reported that the maximum allowed number of re-arms has been exceeded. You must re-install the OS before trying to re-arm again." How can I circumvent this, without losing all the data I have in the VM?

  • Partitioning recommendations for a Proxmox VM Server (OpenVZ)

    - by luison
    We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?

  • How does a hard drive compare to Flash memory working as a hard drive in terms of speed?

    - by Jian Lin
    Some experiment I did with hard drive read/write speed was 10MB/s write and 40MB/s read, and with a USB Flash drive, it can be 5MB/s write and 10MB/s read. Also, if I put a virtual hard drive .vhd file in a hard drive or in a USB Flash drive and try a Virtual Machine using it, the one using the hard drive is quite fast, while the one using the USB Flash drive is close to not usable. So I wonder some early netbooks use 4GB or 8GB flash memory as the hard drive, and even the Apple Mac Air has an option of using flash memory instead of a hard drive. But in those situation, will the speed be slower than using a hard drive, like in the case of a USB Flash drive?

  • Windows 7 XP mode missing driver virtual pc integration device

    - by Charlie Wu
    I have XP Mode installed fine, but the shipped Windows XP installation is too heavy. I tried to install a light XP using my ASUS Eee PC. After installation, I have to install a few missing drivers and everything worked OK except I can't copy and paste between host and guest operating system. I checked Device Manager and found the Virtual PC Integration Device is not installed correctly. I can't find any driver for that. How can I fix this problem?

  • What is the equivalent of Cisco's 'ip virtual-reassembly' for a Juniper ISG 2000

    - by 2xyo
    I tested my dns servers with the oarc test and my size limit is at least 1403 bytes. I performed the same test before my Juniper ISG 2000 and the result is 2047 bytes. According to the chapter IP "Fragments Filtered" and this article, I think I have a fragmentation problem. This article talks about ip virtual-reassembly for cisco but I can't find the equivalent for Juniper. I prefer to find the good option in JunOS before I talk about this with my net admin :-) Thanks

  • Linux Mint 13 64bit Cinnamon and Oracle Virtualbox: 3d acceleration crash

    - by Stephen Swensen
    I've recently got an interest in Linux. After some research, it looks like Linux Mint 13 cinnamon is hot and I thought I'd try it out... I'm running Windows 7 64bit and have experience with Oracle Virtual Box. So I thought it would be a good idea to try out Linux Mint inside Virtual Box. I download Linux Mint 13 64bit Cinnamon and set it up in my VM player... Nothing special about my settings. Except Linux Mint 13 Cinnamon requires 3d acceleration, and when I enable that, it crashes whenever I open the Menu in the bottom left corner of the guest OS (and some other times too)... I've seen other mentions of this problem on the web, but no solutions. Is there a solution? If not, any suggestions short of installing the OS on a partition for trying out this OS (I'm not interested in the LIve mode either - I'd really like to get the full feel for it)?

  • Gateway on a virtual network interface used by LXC guests

    - by linkdd
    I'm currently having some problems with configuring a gateway for a virtual network interface. Here is what I've done : I created a virtual network interface : # brctl addbr lxc0 # brctl setfd lxc0 0 # ifconfig lxc0 192.168.0.1 promisc up # route add -net default gw 192.168.0.1 lxc0 The output of ifconfig gave me what I wanted : lxc0 Link encap:Ethernet HWaddr 22:4f:e4:40:89:bb inet adr:192.168.0.1 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::88cf:d4ff:fe47:3b6b/64 Scope:Lien UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:623 errors:0 dropped:0 overruns:0 frame:0 TX packets:7412 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 RX bytes:50329 (49.1 KiB) TX bytes:335738 (327.8 KiB) I configured dnsmasq to provide a DNS server (using the default : 192.168.1.1) and a DHCP server. Then, my LXC guest is configured like this : lxc.network.type=veth lxc.network.link=lxc0 lxc.network.flags=up Every thing is working perfectly, my containers have an IP (192.168.0.57 and 192.168.0.98). I can ping the host and the containers from the containers and from the host : (host)# ping -c 3 192.168.0.114 PING 192.168.0.114 (192.168.0.114) 56(84) bytes of data. 64 bytes from 192.168.0.114: icmp_req=1 ttl=64 time=0.044 ms 64 bytes from 192.168.0.114: icmp_req=2 ttl=64 time=0.038 ms 64 bytes from 192.168.0.114: icmp_req=3 ttl=64 time=0.043 ms --- 192.168.0.114 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1998ms rtt min/avg/max/mdev = 0.038/0.041/0.044/0.007 ms (guest)# ping -c 3 192.168.0.1 PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_req=1 ttl=64 time=0.048 ms 64 bytes from 192.168.0.1: icmp_req=2 ttl=64 time=0.042 ms 64 bytes from 192.168.0.1: icmp_req=3 ttl=64 time=0.042 ms --- 192.168.0.1 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.042/0.044/0.048/0.003 ms Now, it's time to configure the host as a gateway for the network 192.168.0.0/24 : #!/bin/sh # Clear rules iptables -F iptables -t nat -F iptables -t mangle -F iptables -X iptables -A FORWARD -i lxc0 -o eth0 -j ACCEPT iptables -A FORWARD -i eth0 -o lxc0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward The final test failed completely, ping the outside : (guest)# ping -c 3 google.fr PING google.fr (173.194.67.94) 56(84) bytes of data.
