Hi,
From code how can I set environment variable for apache tomact (Catalina_Home and Path variable)?
Till now I tried this(two ways), it setting the environment variable for tomcat but when I run startup.bat file of tomcat, giving error catalina_home not set. But when I restarted the PC it was working.
Below is my code, what is wrong or what I am missing?
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
static extern bool SendNotifyMessage(IntPtr hWnd, uint Msg,
UIntPtr wParam, string lParam);
private bool SetTomcatEnvironmentVariable()
{
try
{
/*
//Set CATALINA_HOME in User variable
string EnvCATALINA_HOME = System.Environment.GetEnvironmentVariable("CATALINA_HOME", EnvironmentVariableTarget.Machine) ?? string.Empty; //EnvironmentVariableTarget.User
if (!string.IsNullOrEmpty(EnvCATALINA_HOME) && !EnvCATALINA_HOME.EndsWith(";"))
EnvCATALINA_HOME = EnvCATALINA_HOME + ';';
EnvCATALINA_HOME = EnvCATALINA_HOME + @"C:\apache-tomcat-8.0.33";
Environment.SetEnvironmentVariable("CATALINA_HOME", EnvCATALINA_HOME, EnvironmentVariableTarget.Machine);
//Set Path in System variable
string EnvPath = System.Environment.GetEnvironmentVariable("Path", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath.EndsWith(";"))
EnvPath = EnvPath + ';';
EnvPath = EnvPath + @"%CATALINA_HOME%\bin";
Environment.SetEnvironmentVariable("Path", EnvPath, EnvironmentVariableTarget.Machine);
*/
const int HWND_BROADCAST = 0xffff;
const uint WM_SETTINGCHANGE = 0x001a;
using (var envKey = Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Control\Session Manager\Environment", true))
{
Contract.Assert(envKey != null, @"registry key is missing!");
string EnvCATALINA_HOME = System.Environment.GetEnvironmentVariable("CATALINA_HOME", EnvironmentVariableTarget.Machine) ?? string.Empty; //EnvironmentVariableTarget.User
if (string.IsNullOrEmpty(EnvCATALINA_HOME))
{ //EnvCATALINA_HOME = EnvCATALINA_HOME + ';';
EnvCATALINA_HOME = EnvCATALINA_HOME + @"C:\apache-tomcat-8.0.33";
envKey.SetValue("CATALINA_HOME", EnvCATALINA_HOME);
SendNotifyMessage((IntPtr)HWND_BROADCAST, WM_SETTINGCHANGE, (UIntPtr)0, "Environment");
}
string EnvPath = System.Environment.GetEnvironmentVariable("Path", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath.EndsWith(";"))
EnvPath = EnvPath + ';';
EnvPath = EnvPath + EnvCATALINA_HOME + @"\bin";//EnvPath + @"%CATALINA_HOME%\bin";
envKey.SetValue("Path", EnvPath);
SendNotifyMessage((IntPtr)HWND_BROADCAST, WM_SETTINGCHANGE, (UIntPtr)0, "Environment");
}
return true;
}
catch (Exception)
{
return false;
}
}
Please help.
Thanks.
