Release Notes

Changes:

For Macintosh: A problem that if you select "Check Remote Code" or "Check All Code" for Byte-code verification option in Internet Explorer, a security exception may be thrown is fixed.

For Macintosh: A problem that when you show some pages using JSparrow in Internet Explorer 5 continuously, Internet Explorer may crush is fixed.

For IRIX: MIPS n32 ABI version of JSparrow native library and o32 version of that are released. Please use n32 version for JDK and o32 version for Netscape. See Tips and known problems.

For Linux: A problem that JSparrow doesn't run with Netscape is fixed.

For Linux: One known problem is added. See Tips and known problems.

A sample program "HenoHeno" is changed.

Tips and known problems:

Windows

There are some restrictions to run with Internet Explorer.
You cannot use java.awt.Graphics to draw something on OpenGL enabled components (OGLCanvas, OGLPanel etc.). And you cannot add java.awt.Component to those.
Example:

    public class MyOGLPanel extends OGLPanel {
        ...
        public void paint(Graphics g) {
            super.paint(g);
            g.drawString("This message doesn't appear.", 0, 10);
            ...
        }
        public void addButton() {
        	this.add(new Button("This button doesn't apper."));
        }
    }

Tips:

Using appletviewer of Java 2


Copy 'jsparrow.zip' to 'jdk1.2.2\jre\lib\ext' directory.
Add RuntimePermission "loadLibrary.jsparrow" by policytool.

Solaris

Current version (0.944b) of JSparrow has a probrem with the combination of JDK 1.2.2 and Mesa. If you want to run JSparrow with JDK 1.2.2, please use Sun OpenGL instead of Mesa.


Tips:

Using appletviewer of Java 2


Copy jsparrow.zip to jdk1.2.2/jre/lib/ext directory.

Linux

Netscape's Java for Linux has a problem with JNI. Native method cannot returns some objects to Java in standard way. Then currently gluErrorString() and gluGetString() are not supported. But we will fix this problem and release the fixed version in near future.

Tips:

Using appletviewer of Java 2


Copy jsparrow.zip to jdk1.2/jre/lib/ext directory.

IRIX

There are some restrictions for IRIX.
You cannot use java.awt.Graphics to draw something on OpenGL enabled components (OGLCanvas, OGLPanel etc.).
Example:

    public class MyOGLCanvas extends OGLCanvas {
        ...
        public void paint(Graphics g) {
            super.paint(g);
            g.drawString("This message doesn't appear.", 0, 10);
            ...
        }
    }

Tips:

Using appletviewer of Java 2


Copy jsparrow.zip to java/lib/ext directory.

JDK and Netscape

If you want to use JSparrow with both JDK and Netscape, you should consider the path of native library (LD_LIBRARY_PATH). JDK uses n32 ABI version of JSparrow native library and Netscape uses o32 ABI version of that. To avoid resetting of LD_LIBRARY_PATH, we recommend the following setting:
Move n32 version of library to /usr/lib32 and o32 version of it to /usr/lib.
Set LD_LIBRARY_PATH which is NOT include the path of these libraries, /usr/lib32 and /usr/lib.
