Java

I have just recently installed FC3 and am new to Linux. I cannot get java to work at all. Any pages that require the java plugin will not install the plugin. I have tried the manual install (I think I did it right) to no avail.

Any suggestions would be extremely helpful.

Which broswer are you referring to?

Do you have a java runtime or developement environment installed? If so, you can just create a symbolic link from the java plugin installation directory to the plugins directory in your browser's installation folder.

http://java.sun.com/j2se/1.4.2/download.html On this page you can download either J2SE SDK (the development, for compiling java) or J2SE JRE (runtime environment). They will install to /usr/java/j2sdk<version>/ (for SDK). Once it is installed, you would type the following

Code:

ln -s /usr/java/j2sdk<version>/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so /path/to/browser's/pluginfolder/

Note, that you do not copy the .so file to the plugin folder, as that will crash the browser (I am referring to Mozilla and Firefox). I do not know if there is just the plugin available, or if you need to download the whole thing. Though I would recommend that you download the JRE if you don't compile java, and link it as I have above, just make sure that you replace the <version> with the correct version (only one folder will be in /usr/java so just use that).

Let me know how it goes...

If you have the Java SDK, then you can add the following lines to your .bash_profile file which will enable you to compile and run Java applications:

Code:

PATH=/usr/java/j2sdk<version>/bin:$PATH
JAVA_HOME=/usr/java/j2sdk<version>

export PATH
export JAVA_HOME

Now you should be able to compile java programs using "javac" and run them using "java"

I hope this helps

Wait a sec.. were you asking how to make the java plugins in the browser to work, or how to be able to compile & run java programs, or both?

If you are using JRE 1.5.0 the plugin is located in the ns7 directory.

Same steps apply as posted above.
