Run a .exe file using Spring

[ramyareddy]

Hi,
i have a .exe, which i need to execute from my java code(using spring frame work).

I have two cases:
1) .exe file is in local system.
2) .exe file is in remote

Are there any API's available in spring framework to do this.

Thanks for any help.

Ramya.

I would do a general search on the net for running executing exe's from Java.

Hi,
Thanks for that, is there any package provided by the spring for that.
i Need to call the exe file which is located in the remote system.
I am using java's Runtime

Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("C:\\software\\npp.4.0.2.Installer.exe");
int exitVal = proc.exitValue();
System.out.println("Process exitValue: " + exitVal);


Is there any thing specific that i have to do to execute a remote file.
I heard about socket programming, to how extent it will be useful to me.

Thanks for any help.

Ramya.

This isn't really a Spring issue but...

What exactly do you mean by executing a remote file? There's no inherent way to execute a file on a remote system, but there are a few options...

a) Map it to the local computer so that it appears to be a local file. This will run on your system but be stored remotely.

b) Run a server on the remote system that calls Runtime.exec() there. You can do this using the ServerSocket interface or any other language, but it's kind of hacky.

c) Run a remote service using RMI that does the same. Slightly less hacky, but requires Java and some additional constraints.

d) Run a service through some other server container, using some form of CGI or something, possibly calling it via JNDI. I suppose if you really wanted to, you could develop a Spring servlet on the remote computer and have your local servlet post HTTP to it...

e) Make it a web service and call it with SOAP. This is probably the most elegant and buzzword-compliant option.

Without knowing more about the situation, I really can't suggest anything else. It depends on how much control you have over the remote system, how many resources you want to occupy, how much effort you want to put into it and how strong/secure/etc you want it to be.

I'm with the other poster here, I'm confused about what you are actually trying to do. Executing remote files using sockets? Any chance you can explain a little more about what you're trying to do?

Hi,
sorry for the late reply.
What i am trying to say is, there is an executable file say for example addmember.exe(adds a member to a database and some other stuff...) in a remote system. From my java code i need to invoke the exe file so that it is executed in the remote system and adds a member to a database.

For example:
Process p = Runtime.getRuntime().exec("C:\member\addmember.exe ");

I can use java api like this to run the exe file.Still i need to find out how to run if this file is there on a remote system.

Is there any spring specific ways of doing this, with out using the usual java API.

Thanks for any help.

Thanks,
Ramya.

No. This is not in the Spring remit.

The remoting side of this is fine, there are lots of non-Spring and Spring ways of doing this. As for the actual call what's wrong with what you have?

addmember.exe requires two input parameters, which i used to pass through command prompt.With java Runtime(Process p = Runtime.getRuntime().exec("C:\member\addmember.exe ) i didn't have a chance to pass input parameters to the exe.

Is there any other way to pass parameters to the exe.

Thanks,
Ramya.

Would you like first look into the Javadoc for Runtime class, and only then ask questions?

This class contains a horde of different versions of the exec() method which allow for passing parameters, specifying environment variables and working directory.

For example
Process exec(String[] cmdarray)
Executes the specified command and arguments in a separate process.
