Installing JDK JRE + Dr.Java + Android SDK (Eclispe + SDK)

[jhehe]

I need to install jre/ jdk and dr.java as i am currently learning programming in java. also, i will need to install the android sdk package found on the google site (http://developer.android.com/sdk/index.html)

however, i have a few questions.

i'm using linux mint cinnamon and i already saw jre7 installed, but will that work for dr.java? or do i need to install the downloaded jre file?

also, dr.java is compressed/ archived. however, how do i make a short cut/ auto launch application? right now, i have to go in the command line terminal and type in the code in order to launch it:

Code: Select all

java -jre drjava.jar

after typing this, the programming platform launches. however, any way to do something as seen in windows where i can double click an icon to bring up this platform?

I'm not familiar with Dr.Java; you might need a jdk for the compiler. Eclipse has its own. Android will require jdk, and Eclipse is optional.

You might find Oracle jdk more suitable than openjdk. Installation instructions here.

right-click desktop -> Create Launcher

Note, your command should be

Code: Select all

java -jar drjava.jar

(not -jre)

yep, made a typo in my code.

ok, right now, after i create a launcher, i appears that i can't run it still for some reason. it says that the permission is denied. the launcher got created successfully. i went into properties and made sure that i hav read and write permissions and made the file executable.

so any ideas?

permission is denied

Let's see from a terminal:

Code: Select all

$ java -version
$ java -jar drjava.jar  # you said this works, right?
$ ls -l drjava.desktop  # or whatever your launcher is named

The launcher should have correct permissions by default, but I bet it needs an absolute path to the jarfile.

Code: Select all

java -jar /full/path/to/drjava.jar
# e.g., /home/jhehe/Desktop/drjava.jar

ty issue finally fixed, thanks all
