PJA Toolkit forum

bird

We were running PJA tool kit fine under JDK 1.4. Now we need to upgrade to JDK 1.5 for a few different reasons. After the upgrade I am getting this problem:


ava.lang.AbstractMethodError: sun.java2d.SunGraphicsEnvironment.createFontConfiguration()Lsun/awt/FontConfiguration;

Has anyone had a similar problem and can provide some insight?

Thanks.

hi, I got the same problem, have u find any approach to solve it?

JDK 1.5 now has a concept of "font configuration" (as opposed to just "font properties" in JDK 1.4.x). In java.awt.SunGraphicsEnvironment, they've added two new overrides of abstract methods:

protected abstract FontConfiguration createFontConfiguration();
public abstract FontConfiguration createFontConfiguration(boolean, boolean);

and dropped:

protected sun.awt.FontProperties createFontProperties();

The last drop of the PJA implements the latter method in PJAGraphicsEnvironment.

The JDK 1.5 now has FontProperties as being an inner class of PropertiesHandler which is itself a static inner class of the new FontConfiguration class.

To sum up, looks like PJAGraphicsEnvironment will need the implementations of the new methods (createFontConfiguration). There might be a lot more of this kind of problem (I only researched this specific issue since I've been seeing this problem as well).

I also noticed that Sun added a createFontConfiguration() method in sun.java2d.SunGraphicsEnvironment class. Before making any change to PJA Toolkit classes, I discovered that JDK 1.5 finally works correctly on headless systems installed with or without X11 libs.
Thus, I don't think I'll modify PJA Toolkit because I don't see why people should need it with JDK 1.5.
The only remaining case would be for backward compatibility of programs that use only PJA classes for graphics, but these kind of programs don't require GraphicsEnvironment and still work.
Please read http://www.eteks.com/pja/en/forum/viewSubject.jsp?subjectId=481#612 for more information.

I tried most of the options suggested in this forum to resolve issues concerning JDK 1.5 upgrade. Unfortunately, nothing to fixes the issue.
We are using pja 2.5.

The jvm options look like this:

-Dsun.io.unicode.encoding=UTF-8
-Dfile.encoding=UTF-8
-Xbootclasspath/a:pja.jar
-Dawt.toolkit=com.eteks.awt.PJAToolkit
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment
-Djava2d.font.usePlatformFont=false
-Djava.awt.fonts="C:/Program Files/Java/jre1.5.0_06/lib/fonts"

If I run using these options I got the following error:

java.lang.AbstractMethodError: sun.java2d.SunGraphicsEnvironment.createFontConfiguration()Lsun/awt/FontConfiguration;

If I remove all pja related options and add set java.awt.headless=true, then I get Headless Exception.

Has anyone successfully use headless mode in JDK 1.5?

Did anyone get pja 2.5 to work under JDK 1.5???
