Java in a batch file being run via a VB program.

[msimmons]

I know nothing of Java I asked a fellow programmer about this problem I have been messing with and he suggested I try in the Java area (I origonaly posted in the VB area). Please check this out and see if you have any ideas:

the gist of it is as follows

I'm not to sure how this batch file works (basicly it is contacting another co's server and transfering files) but I believe it is through java. I control it via the command window. Will it be hard or even possible to convert to vb?


code:--------------------------------------------------------------------------------
echo off
rem set JDK_BIN=D:\jdk\bin\
SET CLASSPATH=D:\blahxf\java;D:\Blahxf\lib\email.jar;D:\Blahxf\lib\jnet.jar;D:\Blahxf\lib\foo.jar
SET CLASSPATH=%CLASSPATH%;D:\Blahxf\lib\jsse.jar;D:\Blahxf\lib\jcert.jar
JAVA -Xms8M com.Blah.interfaces.pms1way.BlahClient -S Y

Recently I came across a nice VB Class module that executes a DOS command and captures the output to any control (textbox / label) that you like. The good thing about it is that it uses the API to execute the DOS command and therefore you don't get the DOS window - the whole process is invisible.

I use it to read the EXIF data from digital camera files, because the program I have to extract the data is a command line program only.

If you want it let me know and I will post it for you.

the batch file is in a directory on d: and has to be there (I may be able to fix it if I have to but wont be fun ) and I believe the exe has to be in the root of c:. easy right just do this:
d:
cd theDirectory
theBatch.bat

but the d: (and anything but "help" or the batch name) gives the error:


quote:
--------------------------------------------------------------------------------

File or command not found.

--------------------------------------------------------------------------------
I tried (to first switch to the d: directory):


visual basic code:--------------------------------------------------------------------------------
objDOS.CommandLine = "d:"
objDOS.ExecuteCommand
--------------------------------------------------------------------------------

and

visual basic code:--------------------------------------------------------------------------------
temp = "d:"
objDOS.CommandLine = """" & temp & """" 'txtCommand.Text
objDOS.ExecuteCommand
--------------------------------------------------------------------------------

both gave that same error

I can go to the batch file directly like so:


code:--------------------------------------------------------------------------------
d:\theDirectory\Thebatch.bat
--------------------------------------------------------------------------------

and it will run but it has its own error cos it cannot find the files it needs (I may have to just edit it but won't be fun)
OR
I wote a batch file containg this:

code:--------------------------------------------------------------------------------
d:
cd theDirectory
theBatch.bat
--------------------------------------------------------------------------------

now if I run that batch file from the command window it works perfectly but in the program I have the problem where the exe will show up in the task manager but not really run.

any ideas?

I just ran the batch with the full path again and this is the error I get:

I don't know about the batch problem, but the error of the Java app is a NumberFormatException, this means it comes from trying to convert a String that does not contain a number to a number.

That is probably because of it not finding the 'settings' file...
