Running the JavaFX 1.0 SDK on Linux
The JavaFX 1.0 SDK was released today. I’ve played with the preview SDK, so I was pretty excited to try out the 1.0 SDK. Inexplicably, and this was the case with the preview SDK as well, Sun hasn’t released a version of the SDK for Linux. However, this wasn’t a problem because it was possible to run the Mac version of the Preview SDK on Linux. The preview SDK came in the form of a zip, but the 1.0 SDK comes in the form of a dmg, so I was initially stumped. But I’ve figured out how to get the Mac version of the SDK to work on Linux. It’s a little more complicated than getting the preview SDK to work, but it works!
The thing about dmg files is that you can easily mount them on Linux since they are essentially stored in the HFS Plus filesystem format. So I immediately set about trying to mount it:
[email protected] ~ $ mkdir javafx [email protected] ~ $ sudo mount -o loop -t hfsplus javafx_sdk-1_0-macosx-universal.dmg javafx [sudo] password for vivin: mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Hmm… ok, that wasn’t what I expected, so I tried to see what type of file it was:
[email protected] ~ $; file javafx_sdk-1_0-macosx-universal.dmg javafx_sdk-1_0-macosx-universal.dmg: bzip2 compressed data, block size = 100k
Ok, so it look’s like it’s a bzipped file. All we need to do then, is bunzip it and mount it:
[email protected] ~ $ bunzip2 javafx_sdk-1_0-macosx-universal.dmg bunzip2: Can't guess original name for javafx_sdk-1_0-macosx-universal.dmg -- using javafx_sdk-1_0-macosx-universal.dmg.out bunzip2: javafx_sdk-1_0-macosx-universal.dmg: trailing garbage after EOF ignored [email protected] ~ $ sudo mount -o loop -t hfsplus javafx_sdk-1_0-macosx-universal.dmg.out javafx [email protected] ~ $ ls javafx javafx_sdk-1_0.mpkg
Awesome! So we were able to get the dmg mounted. Now all we need to do is find were the SDK lives. After going through the dmg, I found out that the SDK is stored in a compressed (gzipped) file. You can find it at <mountpoint>/javafx_sdk-1_0.mpkg/Contents/Packages/javafxsdk.pkg/Contents/Archive.pax.gz. Copy this file into another working directory (or wherever you want your SDK to reside. I put mine in /usr/local):
[email protected] ~/working $ cp ~/javafx/javafx_sdk-1_0.mpkg/Contents/Packages/javafxsdk.pkg/Contents/Archive.pax.gz . [email protected] ~/working $ gunzip Archive.pax.gz [email protected] ~/working $ file Archive.pax Archive.pax: ASCII cpio archive (pre-SVR4 or odc)
When I gunzipped the file, I got Archive.pax, and I wasn’t sure what to do with it. So I ran file on it and discovered that it was a cpio file. Some quick Googling and man-page perusal later:
[email protected] ~/working $ cpio -i <Archive.pax 65687 blocks [email protected] ~/working $ ls Archive.pax COPYRIGHT.html lib profiles samples src.zip timestamp bin docs LICENSE.txt README.html servicetag THIRDPARTYLICENSEREADME.txt [email protected] ~/working $ bin/javafx Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -d32 use a 32-bit data model if available -d64 use a 64-bit data model if available -client to select the "client" VM -server to select the "server" VM -hotspot is a synonym for the "client" VM [deprecated] The default VM is server, because you are running on a server-class machine. -cp <class search path of directories and zip/jar files> -classpath <class search path of directories and zip/jar files> A : separated list of directories, JAR archives, and ZIP archives to search for class files. -D<name>=<value> set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version:<value> require the specified version to run -showversion print product version and continue -jre-restrict-search | -jre-no-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] enable assertions -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] disable assertions -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:<libname>[=<options>] load native agent library <libname>, e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:<pathname>[=<options>] load native agent library by full pathname -javaagent:<jarpath>[=<options>] load Java programming language agent, see java.lang.instrument
As you can see, you now have a working JavaFX 1.0 SDK on your Linux box!
