A problem with redirect on Windows command line

I'm using CMD under Windows XP to get a command line.  From there, I am issuing a java command with a number of arguments, and trying to redirect the output to a log file.  Problem is (... and I seem to remember something like this many moons ago in my DOS days...) when the command executes, it inserts an additional "1" character before the redirect character ">" and as a result the redirect does not work.

Here's the command in the .BAT file:
  "%JAVA_HOME%\bin\java" -Xms256M -Xmx512M -Duser.language=en -jar ofbiz.jar -install > framework\logs\console.log

.. and here are the results in the cmd window:

C:\>"C:\Program Files\Java\jdk1.5.0_11\bin \java" -Xms256M -Xmx512M -Duser.language=en -jar ofbiz.jar -install  1>framework\logs\console.log

Where is this "1" coming from, and what do I do to avoid it?

Thanks.

One is the desination for standard output. 2 is standard error.

You could do this:

@"%JAVA_HOME%\bin\java" -Xms256M -Xmx512M -Duser.language=en -jar ofbiz.jar -install > framework\logs\console.log

or

@("%JAVA_HOME%\bin\java" -Xms256M -Xmx512M -Duser.language=en -jar ofbiz.jar -install)> framework\logs\console.log

Good Luck,
Steve

I tried the first segment you sent, and I got no output at the command line, so not sure if it worked or not.  (Does the "@" turn echo off?).

The second segment, with the "@" once again stopped any further output to the command line window, so I tried it without "@" and got a similar problem/outcome:  
C:\>("C:\Program Files\Java\jdk1.5.0_11\bin\java" -Xms256M -Xmx512M -Duser.language=en -jar ofbiz.jar -install ) 1>framework\logs\console.log

So, to clarify, I want a way to redirect the output to the logfile, but I also need to see output in the command line window to see what is/is-not executing, and correctly or not.

Thanks.

@ suppresses echo

If you want to see everything then you're going to see the 1. Just know that it mean redirect to standard output. It's the default when you used >.

You could really always give out grade of 'A'.

In my opinion the grading system in EE is worthless. To ask a person who knows nothing about the solution other than what you've given them to grade a question that affects the overall points given to the expert is disturbing... At least to me :)

No back to the question:
