How to execute linux scripts in installanywhere

For more information about how to run linux scripts on installanywhere-general Linux technology-Linux technology and application information, see the following. Another major problem encountered when I learned installanywhere today: executing linux scripts.
I tried a lot of methods and there was no result.
Execute command for the first time
/Bin/sh. sh
It seems that a row is running, or cp;

Execute target File is used for the second time.
No effect.

The third time is execute costom code
I just got in touch with java, but it is not easy to write !!!
Import com. zerog. ia. api. pub .*;
Import java.net .*;
Import java. io .*;
Public class ExecuteTargetFile extends CustomCodeAction
{
Public void install (InstallerProxy ip) throws InstallException
{
Try
{
String fileToExecute = "/bin/sh shsh. sh ";
Process r = runtime.getruntime(cmd.exe c (fileToExecute );
System. out. println (fileToExecute );
} Catch (IOException e)
{
System. out. println ("failed ");
}
}

Public void uninstall (UninstallerProxy up) throws InstallException
{
}

Public String getInstallStatusMessage ()
{
Return "Execute Target File ";
}

Public String getUninstallStatusMessage ()
{
Return "Execute Target File ";
}

}
Still ineffective!
Thank you! Thank you!
