Why is JDK required for running Karaf?
Hi, I ran into an Error when I tried to run karaf on a Windows XP with Oracle JRE 7u5 installed. Error: missing `server' JVM at `C:\Programme\Java\jre7\bin\server\jvm.dll'. Please install or use the JRE or JDK that contains these missing components. I then discovered that the karaf-documentation states that a JDK is required to run karaf. I installed JDK 7u5 and everything went fine. But I have some difficulties explaining to certain customers that they need to install a Development Kit to run this thing. So my question is, why exactly is it required to install JDK? Is there no other way? Thanks. kind regards, christoph smime.p7s Description: S/MIME Cryptographic Signature

Could you try running without the -server flags maybe ? set JAVA_OPTS=-Xmx512M -Dcom.sun.management.jmxremote bin\karaf.bat On Tue, Jul 31, 2012 at 12:15 PM, Christoph Gritschenberger christoph.gritschenber...@gmail.com wrote: Hi, I ran into an Error when I tried to run karaf on a Windows XP with Oracle JRE 7u5 installed.

Re: Why is JDK required for running Karaf?
Hi, the java environment can be defined as server or client ( http://www.oracle.com/technetwork/java/hotspotfaq-138619.html#compiler_types ). Using a JRE under linux provide both server and client option. Using a JRE under windows provides only a client. (the server part is only provided with JDK) When using karaf, the option is set to server so when running under windows, you need the JDK. As users, we noticed that for previous versions. I don't know if current versions need more than this option.

Re: Why is JDK required for running Karaf?
btw, another option to workaround this problem is to provide a custom jre; we typically deliver a JDK with our container, BUT for windows we copy over the bin directory from the JDK over the JRE, this is all required to fix that problem. Just to offer an additional option.

argl.. sorry for the mistake; we provide a JRE copy over the bin dir from the JDK :-) so, no it's correct.

Re: Why is JDK required for running Karaf?
well, looking at [1] I don't think that there is any difference. Since karaf could run as a server BUT also as a client environment we maybe should a) make it possible to switch between those with a param and b) add a fallback solution for windows WDYT? kind regards, Andreas On Tue, Jul 31, 2012 at 1:02 PM, Christoph Gritschenberger christoph.gritschenber...@gmail.com wrote: Hi, With this, I get some syntax-error -Dcom.sun.management.jmxremote ist syntaktisch an dieser Stelle nicht verarbeitbar.

Re: Why is JDK required for running Karaf?
Yes, I think if the default windows JRE does not support server, we should not include this option by default on windows. Unless we can actually find if it's present or not, which would be even better.

any one recall why Karaf requires JDK at the first place?
