The installation and configuration process can be broken down into the following steps:
1. Run the JDK software installer, if necessary
Check the file size - If you downloaded the JDK software file instead of running the installer from your browser, you should check to see that the complete file was downloaded:jdk-1_1_8_006-win.exe 8,798,480 bytesTo run the JDK software installer, double-click on the icon for this file. Follow the instructions the installer provides.
When done with the installation, you can delete the downloaded bundle to recover disk space.
Unbundle the JDK software bundle and the JDK documentation bundle in the same directory. (The docs are available for download from step 2 of the JDK software download page.) Unbundling them in the same directory ensures that HTML links between the bundles will work properly. You can download and install the software bundle and documentation bundle in either order.
Installed Directory Tree
The JDK software and documentation directories will have the following structure. The docs directory and its contents will not be installed until you download and unbundle the JDK software documentation.
jdk1.1.8 _________________________|________________ | | | | | | | | | | | README | | | bin lib | demo | docs | CHANGES | | | | include | src | | COPYRIGHT | | | | | LICENSE index.html
Included in the unbundled files is a file lib/classes.zip. DO NOT UNZIP THE CLASSES.ZIP FILE. This file contains all of the core class binaries, and must remain in its zipped form for the JDK software to use it.
It is possible for you to run the JDK software without modifying any system environment variables (such as PATH or CLASSPATH). However, you should test that CLASSPATH is not set, and most developers set PATH as a convenience.
Windows NT - Make the following environment variable changes in the Control Panel. Start the Control Panel, select System, then click the Environment tab.As a general rule, both PATH and CLASSPATH are defined as User Variables, although a system administrator may wish to define System Variables in some circumstances.
Windows 98 and Windows 95 - Make the environment variable changes to
PATH C:\WINDOWS; C:\WINDOWS\COMMAND; C:\;C:\DOS ; C:\JDK1.1.8\BIN
C:> setThis lists all of the environment variables. CLASSPATH will not appear if it is not set. If it is set, you can unset the current value by setting it to no value:
C:> set CLASSPATH=Also open your startup file (autoexec.bat) or script and remove the path to the JDK classes from the CLASSPATH environment variable, if you want the change to be permanent.
.;[bin]\..\classes;[bin]\..\lib\classes.zipwhere [bin] is substituted by the absolute path to the jdk1.1.8\bin directory. Therefore, if you keep the bin and lib directories at the same directory level (that is, if they have a common parent directory), the Java technology executables will find the classes. You need to set the CLASSPATH only if you move classes.zip or want to load a different library (such as one you develop).
Your computer system should now be configured and ready to use the Java Development Kit. You start a tool by typing its name into the DOS window with a filename as an argument. None of the Java tools are Microsoft Windows programs with GUI interfaces -- they are all run from the DOS command line. You cannot run any JDK software tool by double-clicking on its icon.
You can specify the path to a tool either by typing the path in front of the tool each time, or by adding the path to the system as in the previous step.
Documentation for all the JDK software tools can be found in your installed JDK documentation.
- Run the compiler on a source file.
For example, if the JDK software is installed at
C:\jdk1.1.8, to compile the source file
myfile.java, go to a DOS shell and execute this:C:> C:\jdk1.1.8\bin\javac myfile.javaor, if you have already added
C:\jdk1.1.8\binto your path:C:> javac myfile.java
Refer to the Troubleshooting section below if you have problems running the JDK software.
- Run an applet in AppletViewer.
The AppletViewer is a application for running and viewing applets in a window. You can start the AppletViewer by executing the following, assuming you have already set your path (as described above):
cdto change to a directory containing an html file that embeds an applet. JDK1.1.8 contains the TicTacToe applet in the demo directory:C:\> cd jdk1.1.8\demo\tictactoe
- Run the AppletViewer passing in the html file:C:\JDK118\DEMO\TICTACTOE> appletviewer example1.html
If you should ever want to uninstall the JDK software, go to the Start menu and select Settings, then select Control Panel. In the Control Panel, open the Add/Remove Programs utility. You will be presented with a list of software that you can uninstall. Simply choose the JDK software from the list and click the "Add/Remove..." button.
net.socketException: errno = 10047-or-
Unsupported version of Microsoft Windows Socket APIcheck which TCP/IP drivers you have installed. The AppletViewer supports only the Microsoft TCP/IP drivers included with Windows 95. If you are using third-party drivers (e.g., Trumpet Winsock), you'll need to change over to the native Microsoft TCP/IP drivers if you want to load applets over the network.
java -verbose sun.applet.AppletViewerThis lists the classes that are being loaded. From this output, you can determine which class the AppletViewer is trying to load and where it's trying to load it from. Check to make sure that the class exists and is not corrupted in some way.
C:\> set CLASSPATH=.;C:\jdk1.1.8\lib\classes.zipThis will ensure that you are using the correct classes for this release.
setThis will list all of the environment variables that are set. JAVA_HOME will not appear if it is not set. If a value is set for JAVA_HOME, unsetting it should allow you to run the JDK tools. You may want to make a note of the current JAVA_HOME setting before you unset it, in case you want to restore it later. You can unset the JAVA_HOME environment variable by setting it to no value, as follows:
set JAVA_HOME=If you still cannot run the JDK tools after unsetting JAVA_HOME, you can try setting JAVA_HOME to the absolute path of the jdk1.1.8 directory that was created when you installed the JDK software. For example, if the directory jdk1.1.8 has the path C:\java\jdk1.1.8, you can try setting JAVA_HOME as follows:
set JAVA_HOME=C:\java\jdk1.1.8As long as you have not disturbed the bin and lib directories that are immediately below the jdk1.1.8 directory, you should be able to run the JDK tools.
AppletViewer allows you to run one or more Java applets that are called by reference in a web page (HTML file) using the APPLET tag. The AppletViewer finds the APPLET tags in the HTML file and runs the applets (in separate windows) as specified by the tags.C:\> bin\appletviewer
AppletViewer is for viewing applets. It cannot display an entire web page that contains many HTML tags. It parses only the APPLET tag and no other HTML on the web page.
To run an applet with appletviewer, you go to a command line for your operating system and run appletviewer, passing in the filename or URL of the web page as its argument.
Here is an example of how to invoke AppletViewer on a file-based web page in Microsoft Windows. Go to a DOS prompt, change to the "jdk1.1.8" directory and then execute:C:\ bin\appletviewer demo\GraphLayout\example1.htmlHere is an example of how to invoke AppletViewer on a URL-based web page in Microsoft Windows.
