Accessing Manifest file

The manifest file contains a description of package related data contained within a Jar archive. Strings stored in MANIFEST.MF can include version and company information, the name of the main method in executable jar files and secure-digest information. Here is a simple example that illustrates the technique for accessing the data contained in MANIFEST.MF
Given the following Manfiest.mf file in the META-INF directory of a jar file:Manifest-version: 1.0 Name: com/mycompany/ourstuff/Implementation-Title: com.mycompany.ourstuffImplementation-Version: 21Implementation-Vendor: My Company
You can access the information contained within the Manifest using the following:Package versionInfo = Package.getPackage("com.rkcole.mystuff");String revision = versionInfo.getImplementationVersion();String vendor = versionInfo.getImplementationVendor();String title = versionInfo.getImplementationTitle()

Trick to make netbeans fast

Hi,

There is a file named 'netbeans.conf' which can be found in \etc\ which you can edit to increase the amount of memory that NetBeans runs with. Edit the property named 'netbeans_default_options'. Increasing the -Xms and -Xmx options will increase the amount of RAM avialable to the JVM that NetBeans will be running inside of.
Example:
netbeans_default_options="-J-Xms384m -J-Xmx512m -J-XX:PermSize=32m -J-XX:MaxPermSize=96m -J-Xverify:none"

This example will allow NetBeans to run with a minimum of 384 megabytes of RAM and a maximum of 512 megabytes of RAM.

Cheers!
