通过Web Start启动JNLP后在哪里下载JAR文件

Question

Where are the JAR files downloaded after launching a JNLP through Web Start?

I have searched in my home directory in appdata/local... , but it is showing .jnlp file instead of .jar .

Answer 1

just run the below command and then select resources in the tool

javaws -viewer

Answer 2

Since you mentioned "appdata" I assume you are running webstart on windows - on an other OS things obviously are different.

The location of the downloaded JARs has changed some versions ago, but current versions use C:\\Users\\<your userid>\\AppData\\LocalLow\\Sun\\Java\\Deployment\\cache (at least on my Windows 7 machine, but I think it should be the same for newer Windows versions).

Note that under the cache -directory there is an additional folder structure and also note that the JAR-files are not saved under the same name that they are stored on the server but using some computed value - and not even using the .jar -extension (eg one of our JAR-files is stored as 6cb5c740-6bb35453-1.0- ).
