2.0 Alpha 3 Release Notes

READ THIS Before You Build and Install

We have a source and binary releases now, and they are only known to work on win32

`

Webclient 2.0 Alpha 3 depends on Mozilla 1.7. If you build webclient from source, you must first build Mozilla. For instructions on building Mozilla 1.7 please visit http://www.mozilla.org/build/.

Installing the 2.0 Release

Win32

This section explains how to install and run webclient using the win32 binary distribution.

  1. Un-install any existing webclient installations.

  2. Install JDK 1.4.2 from http://java.sun.com/j2se/1.4.2/download.html. Older JDKs may work but you're on your own for support.

  3. Set the system environment variable JDKHOME to be the location where you installed the JRE. Note!!!, if you installed the JRE into a directory like C:\Program Files\jdk1.4.2\JRE, which contains spaces, you must use the funky ~1 convention for long filenames. That is, 

    JDKHOME=C:\PROGRA~1\jdk1.4.2\JRE

  4. Install Mozilla 1.7, from http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.7/mozilla-win32-1.7.zip. It's important to use the zip installer because the other installers put dependent libraries in places where webclient can't find them.

  5. Run the browser installed in the previous step and configure any proxy settings you may need to operate the browser. Exit the browser.

  6. Install Jakarta Apache Ant 1.6.1. If you don't know what ant is, you have no hope of building an application on top of webclient. Go learn about ant at http://ant.apache.org/ and come back when you do. Previous versions of ant had a problem with the javah target under JDK 1.4, so you must use 1.6.1 or later.

  7. Download the binary at http://www.mozilla.org/projects/blackwood/webclient/bin/win32/webclient_2_0_a3_win32.zip. Unpack it into the same directory as your mozilla.exe from mozilla 1.7.

  8. cd to the directory in which you unpacked the zip. Run the command ant. This will run the test browser. To get started developing, look at the source code for the test browser at http://lxr.mozilla.org/mozilla/source/java/webclient/test/manual/src/classes/org/mozilla/webclient/test/TestBrowser.java.

Building the 2.0 Alpha 3 Release

Build Instructions -- Cross Platform

This section explains the steps one has to perform before building 2.0 Alpha 3 on any platform.

  1. Get the mozilla 1.7 source tarball.

  2. Build Mozilla 1.7 WITH DEBUG ENABLED. For instructions on how to do that, go to http://www.mozilla.org/build/. Let's assume you built it into directory $MOZILLA.

  3. Once Mozilla 1.7 is successfully built, you must run it to create a profile, then you must configure the proxy settings, if you are behind a firewall. If mozilla can't see external web pages, neither can webclient.

  4. Install JDK 1.4.2 from http://java.sun.com/. We have made an effort to not have any Java2 specific usage in the webclient code, but we haven't tested webclient with older JDKs. It's likely that webclient will work with older JDKs, but some small tweaking may have to be done. There is a bug on this. See the Known Bugs section of this document.

  5. Install Jakarta Apache Ant 1.6.1. If you don't know what ant is, you have no hope of building webclient from source. Go learn about ant at http://ant.apache.org/ and come back when you do. Previous versions of ant had a problem with the javah target under JDK 1.4, so you must use 1.6.1 or later.

  6. Install JUnit 3.8.1. If you don't know what junit is, you have no hope of running the webclient unit tests, which one must run as a precondition to checkin. Learn about JUnit from http://www.junit.org/.

  7. Obtain the source. You can use a source tarball, or check it out from CVS.

    1. Unpack the webclient source, from http://www.mozilla.org/projects/blackwood/webclient/src/webclient-src-2_0_a3.zip into $MOZILLA.

    2. Check out the webclient source from CVS. Follow the instructions at http://www.mozilla.org/catalog/development/compiling/cvs-sourcecode.html then checkout the CVS module called Webclient .

      This will give you the following directory hierarchy

      $MOZILLA
  java/
   build.xml
   config/
   dom/
   external/
   util/
   webclient/

  8. In addition to the environment variables required for building mozilla, make sure the following environment variables are defined:

    JDKHOME, MOZ_JDKHOME, JAVA_HOME,
    all of the above must be set to the absolute path to your JDK installation. For example, C:\jdk1.3

    MOZILLA_FIVE_HOME
    the mozilla bin directory. For example, D:\Projects\mozilla\dist\win32_d.obj\bin

    ANT_HOME
    the ant install directory. For example, D:\Files_2k\apache-ant-1.6.1

    BUILD_WEBCLIENT_ONLY
    1

    MOZ_SRC
    Set to the parent directory of your top level mozilla directory, for example D:\Projects\mozilla\MOZILLA_1_6

    XPCOM_DEBUG_BREAK
    warn

    NSPR_LOG_MODULES
    webclient:4,webclientstub:4

    NSPR_LOG_FILE
    logfile.txt

  9. Make it so the native makefiles are generated.

    1. prepend the contents of $MOZILLA/java/makefiles to the add_makefiles entry in the file $MOZILLA/allmakefiles.sh.

    2. cd to $MOZILLA and re-run ./configure. When this is done, you should have the following makefiles generated. If you don't, please post to the newsgroup. 

      $MOZILLA
  java/
    dom/jni/Makefile
    dom/src/Makefile
    webclient/src_moz/gtk/Makefile
    webclient/src_moz/Makefile
    webclient/src_ie/Makefile
    webclient/src_share/Makefile

  10. create a $MOZILLA/java/build.properties file that contains the following contents: 

    # if this were unix, you'd have build.unix.classes=true
build.win32.classes=true
# this is where the .class files will end up
build.home=D:\\Projects\\mozilla\\MOZILLA_1_4\\mozilla\\mozilla/dist/classes
compile.debug=true
junit.jar=D:\\Files_2k\\junit3.8.1\\junit.jar
#native.waitForDebugger=true
#debug.jvm.args=-Xdebug -Xrunjdwp:transport=dt_shmem,address=jdbconn,server=y,suspend=y

Build Instructions -- Win32

  1. set MOZ_DEBUG=1 in your environment

  2. set PATH so that it contains %JDKHOME%\bin, %JDKHOME%\jre\bin, %MOZ_TOOLS\bin, %MOZILLA_FIVE_HOME% and %MOZILLA_FIVE_HOME%/components.

  3. Follow the instructions in Build Instructions -- Cross Platform

  4. cd $MOZILLA\java

  5. run the command ant

    This will build the mozilla util classes, the javaDOM, and webclient.

  6. Make sure mozilla is not running on your machine. cd $MOZILLA\java\webclient

  7. run ant test . This will run the automated JUnit tests. If these all run successfully, you're in good shape.

  8. Still without mozilla running, run ant run.test.browser this will run a simple test browser, taken from the JDIC project.

Uninstalling the 2.0 Alpha 3 Build

Uninstalling if you're using the binary install

  1. Stop any running mozilla or webclient instances

  2. cd $MOZILLA_FIVE_HOME

  3. rm -rf javadev

Known Issues

Browser and General Issues

  • Webclient hasn't yet been stress tested, so there are probably lots of issues that will come up with a little use.

Printing

Printing is not yet implemented.

Plugins

You can run plugins inside webclient, but on win32, the Java plugin will not work. You must remove the java plugin. Please see the section on installing the win32 binary in this file.

Bookmarks and History

Both the Bookmarks and History interfaces are incompletely implemented.

Profiles

If webclient is acting funny, it may be due to conflicting mozilla registry file. Follow the steps in the mozilla 1.7 release notes to remove the registry, then re-run mozilla 1.7 to generate a new registry.
