Automating -createPasswordFile in Windows
I'm currently trying to automate the set up of JBEs on Windows environments. I'm at the point of creating the password file using:
jbe.bat -createPasswordFile
jbe.bat -createPasswordFile
Which launches a Java process requesting user input. I would like to know if it's possible to redirect input to the process which is launched, auto-completing the request for a password. For reference purposes our solution in Linux is:
echo "${jazz_password}" | ./jbe.sh createPasswordFile
Accepted answer
Your problem is related more to Windows batch file restrictions than the command itself. By running the JBE launcher jar directly I was able to get this to work:
C:\tmp\IBM\jbe>set JAVA_HOME=C:\IBM\Rational\RTC\RTC-Eclipse\4.0.6\jazz\client\eclipse\jdk
C:\tmp\IBM\jbe>echo secret | %JAVA_HOME%\jre\bin\java -jar C:\IBM\Rational\RTC\toolkits\4.0.6\buildtoolkit\jazz\buildsystem\buildengine\eclipse\plugins\org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar -createPasswordFile tom
*** Warning: password will be printed to the screen.
password:
Password stored in file: "C:\tmp\IBM\jbe\tom"
*** Warning: The password is encrypted to prevent casual observation, but a determined attacker may discover the password. The password file should be protected with operating system file permissions.
This yielded the following password file (* substituted for ? and ! due to editor restrictions):
C:\tmp\IBM\jbe>type tom <*xml version="1.0" encoding="UTF-8"*> <*DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <comment>4.0</comment> <entry key="password">TW6nCXFrd+4=</entry> </properties>

FYI you can further refine this to prevent any output to the console by redirecting the output to the nul device:
C:\tmp\IBM\jbe>echo secret | %JAVA_HOME%\java -jar C:\IBM\Rational\RTC\toolkits\4.0.6\buildtoolkit\jazz\buildsystem\buildengine\eclipse\plugins\org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar -createPasswordFile tom > nul 2>&1
Alan, thanks for the quick and concise response, I really appreciate it!
