Dependency error in jasper-reports from itext

Then I can access any property of … Read more

How do I bundle a JRE into an EXE for a Java Application? Launch4j says “runtime is missing or corrupted.”

by

The only way I could bundle a JRE was to use Launch4J and Inno Setup Compiler. First, create a jre6 folder (for example) in the same directory as your output file (.exe). Then copy the JRE from your system into your jre6 folder. Then you open Launch4J and set the Bundled JRE path – just … Read more

JAR – extracting specific files

From the source: To extract only certain files from a jar file, supply their filenames: C:\Java> jar xf myFile.jar foo bar Using wildcards is a shell thing, and you should not expect it to work when extracting from a JAR file (which, as you’ve realized, is the case). What you can do, is supply a … Read more
