Alternative of jrew for jre1.2.2_007

Question

The below given condition is tested on windows NT 4.0
In JDK 1.1.8 version we used jrew.exe to run our application to avoid the console window(command prompt window) which opens up when jre.exe is used. We currently have a requirement of running our application in JRE1.2.2_007 version. We have installed JRE1.2.2_007 by downloading "jre-1_2_2_007-win-i.exe" from www.sun.com/Download4 site, we however find that JRE1.2.2_007 does not have jrew.exe in it. Kindly let us know the alternative executable that can be used in place of jre.exe with 1.2.2_007 version of Java.
We have tried to the same using javaw.exe which comes with jre1.2.2_007 but in that case DOS prompt is displayed for a moment which we don't want.

Hi kausikdhar,
There are two ways you can run your Java application without bringing up the doc command window.
1. Create a shortcut for your application and provide target for this shortcut as:
javaw -cp C:"mypath" myclass. Then set the working directory to the directory your class file is in. If your Java environment is configured correctly your shortcut will automatically run the application.
2. Use jar tool.
For example, if the main method was in the file, myclass, create a manifest file, for example, mymanifest, with the following lines:
Manifest-Version: 1.0
Main-Class: myclass
The JAR file is created as follows:
jar cmf mymanifest myjar myclass.class
You can include other classes in the JAR file by adding them to the end of the command line. To execute this JAR file, called myjar, you can either double click on the myjar icon or use the command java -jar myjar.
Hope thsi helps.
