The application element indicates that the JNLP file is launching an application (as opposed to an applet). .. Arguments can be specified to the application by including one or more nested argument

I know java webstart is running under a secure sandbox. Is it possible to include a .dll/.exe in the jar (or have the webstart download it to the local machine) and then execute it (using Runtime.exec or process,etc) Please Advise. Any suggestion/comment is welcome! Yes. You have to wrap the .dll in a .jar file, and reference it in your .jnlp file using <nativelib> See here for a more detailed description. If you want to run an executable, then your best bet is to package it up in your .jar as a resource, explode it to (say) a temporary directory, and then run it using the normal Process

Some of our customers cannot run our Java Web Start client anymore since Java 8 Update 111. They get: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required Looks like it has to do with this change : Now, proxies requiring Basic authentication when setting up a tunnel for HTTPS will no longer succeed by default. If required, this authentication scheme can be reactivated by removing Basic from the jdk.http.auth.tunneling.disabledSchemes networking property, or by setting a system property of the same name to "" ( empty ) on the command

I am launching a Java Web Start application which shuts down abruptly. Does anybody know how to access the logs for Java Web Start. Are there any known reasons for it to shut down abruptly? assylias You should enable detailed trace logging as explained on this page .

Your cert does NOT have to be signed, but unsigned certs will prompt the client with a trust message that they can ignore. See the below answer for more details We have an internal application which we have been using for many years now. In order to make maintenance easier for this application we have not provided an installable version of the application to our employees, we simply give them a link to a .jnlp and use JWS to launch it on their box.
