PJA Toolkit forum

Hi,

I want use PJA 2.4 on AIX 4.3.3.11 with IBM JDK 1.3.1

My launch command is
/usr/java131/bin/java -Xbootclasspath/a:./rdfax11/pja.jar \
-Dawt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-Djava2d.font.usePlatformFont=false \
-Djava.awt.fonts=/usr/java131/jre/lib/fonts \
-Duser.home=. \
-classpath ./rdfax11/pjatools.jar:./rdfax11/rfax.jar:. \
rdfax11.FaxTest3


Could you explain me this error message
I think this is problem with DISPLAY because there is no X server on my AIX.
It seems me PJA don't need X server ???

Other informations
* I haven't added any new Font on my server.
* My AIX server has some X11 library like X11.base.lib, X11.base.rte, X11.motif.lib, X11.motif.mwm .
* I have also /usr/java131/jre/bin/libawt.a and /usr/java131/jre/bin/libawt_g.a .
* echo $LD_LIBRARY_PATH is empty
* Java instruction line is Font textFont=new Font("Serif",Font.PLAIN,12);

Where is my mistake ??
Best regards

Please, note that it looks like font support doesn't work correctly in PJA Toolkit on AIX from the many messages about this subject on this forum.
Just one thing : do you have any True type fonts files in /usr/java131/jre/lib/fonts directory ?

Hi,

I think that philfr89's config is good. I think it's a problem with ibm's jvms. I can mak pja work under linux with sun's jvm, but I can't make the ibm jvm 1.3.x work with pja:
sun.awt.X11GraphicsEnvironment.initDisplay

Have you heard about ibm / pja problems ?

blav

I phil, have you solved your pb ? I have the same pb under linux with *IBM* jvms. Let me know if you find a solution.

blav

I finally found the solution :
1. copy the arial.ttf font from windows to your $FONTDIR dir
2. if you're using the 1.3.1 ibm jvm, add the -Dos.name=fake to your java cmdline. you don't need this with a 1.3.0 ib jvm

atool

I tried similar approached with 1.3.1 IBM JVM on AIX 5.1 but it didn't work.
Can you highlight little bit that Why do we need -Dos.name=fake ?
and How come copying arial.ttf solved your problem.
Are you using just arial font?
Did you try to copy any other fonts ?
I am using "Times roman" and bunch of other fonts.
Any advice ?

Hi,

I just come from Holiday, i have only realise one test with theses parameters
/usr/java131/bin/java -Xbootclasspath/a:./rdfax11/pja.jar \
-Dawt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-Djava2d.font.usePlatformFont=true \
-Djava.awt.fonts=/u/phi/myclasses/rdfax11/fonts \
-Duser.home=. \
-Dos.name=fake \
-classpath ./rdfax11/pjatools.jar:./rdfax11/rfax.jar:. \
rdfax11.FaxTest3


All my PC Font has been copy to server by FTP .
(http://java.quest.com/support/search/JclServerChart/fq/jcl_serverchart_fq_13.html )


Arial TTF file are :
<e30>phi$ ls A*
AdobeFnt.lst AMAZR___.TTF ANTQUAI.TTF ARIALNB.TTF
AMAZB___.TTF ANTQUABI.TTF ARBLI___.TTF ARIALNI.TTF
AMAZI___.TTF ANTQUAB.TTF ARIALNBI.TTF ARIALN.TTF

<e30>phi$ ls a*
app775.fon app852.fon app857.fon arialbd.ttf ariali.ttf ariblk.ttf
app850.fon app855.fon app866.fon arialbi.ttf arial.ttf



I haven't modify copy or change file font.properties .


I haven't previous error message, but i have null error message on.
follwing instruction

public Font textFont=new Font("Serif",Font.PLAIN,12);
java.awt.Image pageImage=new BufferedImage(800,550,BufferedImage.TYPE_INT_RGB);
Graphics g=pageImage.getGraphics();
g.setFont(this.textFont);
int lineH=g.getFontMetrics().getHeight(); // Null error Message Here



So i think my Font is not find or use in fact. I need perhaps another configuration file for using fonts ???

Could you confirm me that usePlatformFont and awt.fonts parameters are good ?

What is "fake" for os.name parameter ?, i don't find it in documentation ?

Thanks very much.

Unfortunately - at least with the build we have in house, which is "J2RE 1.3.1 IBM AIX build ca131-20031105", and running on AIX 4.3 - the SunGraphicsEnvironment class tries to load the sun.awt.X11GraphicsEnvironment class if the "os.name" system property is "Linux", "AIX", "z/OS", or "OS/390". The code catches ClassNotException and NoClassDefError but not InternalError, which is thrown by the X11GraphicsEnvironment class, when a display is not available to connect to.

This is the reason, why the os.name fix works. Copying the font file is - in my opinion - not really needed.

I'm not sure, whether just setting the os.name property to an other value is a stable solution as the application may make use of it ....

I copied all arial fonts from windows to java/jre/fonts directory in linux and added the argument -Dos.name=false but still I can not see the text fonts on graphics. The bar chart graphic shows but it has no label. There were no erro messages either. Any idea? I have ibm jvm 1.3.1 on limux system. The application is a browser app that get the graphics data using cewolf from linux server and displaying the graph on local system browser - IE and Firefox. PJA is 2.5.

As soon as I change the 2d font value from false to true it started working
(-Djava2d.font.usePlatformFont=true ). I did not even add line -Dos.name=fake.

Thanks for all the forum help.
