Created attachment 144576 [details] Suggested patch for problem 1 and 2 Netbeans platform applications doesn't work correctly with security changes in new JRE versions. I haven't made a detailed tests on all versions but the problems I report occurs in update 45 and 51. Problems: +1+ main="true" is not specified in <jar href="startup.jar"/> and main class isn't found +2+ Property netbeans.user isn't correctly received by netbeans because neither the jnlp is signed and it's not a security property. I've seen that there is an open bug to make jnlp signed but I think that also secure properties had to be used because some times signing jnlp can be a problem. +3+ When 1 and 2 is solved application starts but com.sun.jnlp.JNLPClassLoader.getPermissions(Unknown Source) are throw. Possibly due to missing Codebase attributes in jars manifest (https://community.oracle.com/thread/2552412) I think that a complete revision has to be made to ensure webstart applications work with newer versions. I attach a suggested patch for +1+ and +2+
Please what environment do you use? Problem +3+ with codebase and permissions attributes should be fixed in https://hg.netbeans.org/core-main/rev/61635a07cdc7.
(In reply to Martin Kozeny from comment #1) > Please what environment do you use? Problem +3+ with codebase and > permissions attributes should be fixed in > https://hg.netbeans.org/core-main/rev/61635a07cdc7. I've tested in several windows (windows 7, windows XP) and with JRE7U45 and JRE7U51. To invoke application I've tested from browser and using javaws command.
I had mainly in mind what version of NetBeans do you use. I'm using: Product Version: NetBeans IDE Dev (Build 201401270001) Updates: Updates available Java: 1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08 Runtime: Java(TM) SE Runtime Environment 1.7.0_45-b18 System: Linux version 3.5.0-37-generic running on amd64; UTF-8; en_US (nb) and it works fine for both 7u45 and not for 7u51. With your patch it is working also for 7u51. Problems with codebase and permissions attributes should be fixed in issue #238098.
