how to open and import files in Zeves within Java

[irou]

Hello,
this code let me execute Z\eves within java, but now, i want to open a file and to import an other one.

String[] cmd = {"C:\\Python23\\pythonw.exe", "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw"};                    File workingDir = new File("C:\\Program Files (x86)\\Z-EVES 2.3.1\\gui");try   {  Runtime r = Runtime.getRuntime();  Process p = r.exec(cmd, null, workingDir); }catch(Exception e1) {                       System.out.println("erreur d'execution " +  e1.toString());                   }

Please, how can i do that
thank you

You will need to provide more details: open the file for what? What do you mean with "import a file"?

Cheers,
Dian

I'm developping an application with java.
It's about transforming an XML schema to Z specification.
So,I have to generate a .tex file(after transformations done with XSLT.
In my editor, i have to execute Z/Eves and open this file(.tex): It means I have a button TRANSFORM(on click) Z/eves is executed and specification written in the file (.tex)is opened.

I wish that's clear now

With java.awt.robot you can navigate the mousecursor to click a button. A curious approach, but possible.

my problem here is how to complete this code to open my file .tex like when i want to open a file with notepad for exemple i do that

 Runtime.getRuntime().exec("C:\\Program Files (x86)\\Notepad++\\notepad++.exe "+file.path);

here, where should i insert the file path

String[] cmd = {"C:\\Python23\\pythonw.exe", "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw"};   
 File workingDir = new File("C:\\Program Files (x86)\\Z-EVES 2.3.1\\gui");
try   { 
 Runtime r = Runtime.getRuntime();  
Process p = r.exec(cmd, null, workingDir); 
}catch(Exception e1) {                      
 System.out.println("erreur d'execution " +  e1.toString());                   }

Have you read my response to your thread of the same problem?

I did not post it lightly. You need to wrapper the path to pyw file with quotes because the path contains spaces.

String[] cmd = {"C:\\Python23\\pythonw.exe", "[highlight]\"[/highlight]C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw[highlight]\"[/highlight]"};
[/tt]

@tsuj:
If you have a Program a.exe and want to pass as argument a file b.txt, maybe using an option "-x 3", and you put it into one, big String, then you have to take care to mask your blanks:

"c:/program files/a.exe -x 3 d:/my data/b.txt"

will not work.
But if you put every part in a separat Sting, it should work:

cmd = {"c:/program files/a.exe", "-x", "3", "d:/my data/b.txt"};

@irou: Your filepath shall be the 3rd string in cmd, as far as I can tell.

String[] cmd = {"C:\\Python23\\pythonw.exe", "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw", "Y:/our/file.path"};

Instead of two backslashes you may use single forward slashes.

this code is correct and it allows me to execute Z\eves

String[] cmd = {"C:\\Python23\\pythonw.exe", "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw"};    File workingDir = new File("C:\\Program Files (x86)\\Z-EVES 2.3.1\\gui");try   {  Runtime r = Runtime.getRuntime();  Process p = r.exec(cmd, null, workingDir); }catch(Exception e1) {                       System.out.println("erreur d'execution " +  e1.toString());                   }

Now,I want to open this file (.tex) when Z\eves is executed,where should i insert my file's path?

String cheminfichier=ExportVersXML.path+".tex";

 

[irou]

my file path is like this one:
C:\Users\irou\Desktop\exemple.tex

 

[tsuji]

@stefanwagner: But that is clearly intended to be the first argument being the full path pointing to a pyw file, and that is needed as far as the cmd window on windows os. Well, I pass and it needs only a simple test to establish the need.

 

[stefanwagner]

@irou: How could you start your program from the windows shell?

pythonw "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.py" "C:\Users\irou\Desktop\exemple.tex"

@tsuji: You mean that pythonw needs the masking? Maybe. On Linux I open the file in "Ubuntu One" simply like this:

String[] cmd = {"/usr/bin/gedit", "/home/stefan/Ubuntu One/triangles.txt"};   

File workingDir = new File ("/home/stefan/proj");
try   
{  
	Runtime r = Runtime.getRuntime ();  
	Process p = r.exec (cmd, null, workingDir); 
}
catch (Exception e1) 
{                       
	System.out.println ("erreur d'execution " +  e1.toString ());
}

If you use the shell to execute such a program, so that you have another layer of indirection, you will need the masking ('start -c "Co mand"').

String[] cmd = {"C:\\Python23\\pythonw.exe", "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw", "C:/Users/USER/Desktop/exemple.tex"};
				  
 File workingDir = new File("C:\\Program Files (x86)\\Z-EVES 2.3.1\\gui");
  try  {
	 Runtime r = Runtime.getRuntime();
					  
	r.exec(cmd,null , workingDir);
			         
 }catch(Exception e1) {
				     
System.out.println("erreur d'execution " +  e1.toString());
				   }

I try with this code, Z-eves is executed but there is no file, it means my file is not opened
My file should be there in cmd or no?
I don't understund what cmd shoud contain
I tried all possiblilities but My file is not opened

 

[stefanwagner]

Your file is constantly changing. Now in C:/Users/USER/Desktop, before in
C:\Users\irou\Desktop\exemple.tex - where is it?

As far as I understand

String[] cmd = {
  "C:\\Python23\\pythonw.exe", 
  "C:\\Program Files (x86)\\Z-Eves 2.3.1\\gui\\toplevel.pyw",

is correct so far?

In the windows menu, there is an entry 'Run command' or the like. If you insert cmd there, you get a shell.

Test String[] cmd = {
"C:\Python23\pythonw.exe"
"C:\Program Files (x86)\Z-Eves 2.3.1\gui\toplevel.pyw" "C:\Users\irou\Desktop\exemple.tex"
[/code]
there, or whatever the path to your tex-file is. Use single backslashes in the shell.

Does it work? If yes, translate the path of the texfile to java (double backslash or single slash forward). If not - what's the error? The error-message?

Report the exeption, if there is one.

@stefanwagner
My file path is C:\Users\USER\Desktop\exemple.tex

what shall i write exactly in shell :
I have this: C:\Users\USER>

 

[stefanwagner]

I'm sorry, the formatting was broken, and I didn't realize it.

You shall write your 3 strings, masked with ", the first being the full path of pythonw.exe, the second the python script toplevel.pyw and the third one the tex-file, where ether it is.

"C:\Python23\pythonw.exe" "C:\Program Files (x86)\Z-Eves 2.3.1\gui\toplevel.pyw" "C:\Users\USER\Desktop\exemple.tex"

Don't produce a manual linebreak - I didn't, it might be the weblayout.

I write this but nothing is executed or written.there is no error but nothing happens.

"C:\Python23\pythonw.exe" "C:\Program Files (x86)\Z-Eves 2.3.1\gui\toplevel.pyw" "C:\Users\USER\Desktop\exemple.tex"

I try all possibilities with slashes and backslashes and when Z-Eves opened there is no file.

 

[stefanwagner]

If there is no file, how should it be opened from java?
