Re: trouble with Font objects in Tomcat
Look at this link:
http://java.sun.com/j2se/1.4.2/docs/guide/awt/AWTChanges.html#headless
This option is being used when you are operating on a machine without
graphics support (usually in a server configuration). You will use the
option for example when you want to do some AWT/Swing operation on the
server side (image manipulation). You want to check and see if you have
graphics support on your server (on unix/linux run something like xcalc
on the server).
Based on your information, it is your class that has problem and has
nothing to do with graphics.

What exactly is its purpose? Thanks in advance.

Hello,
I have a web application that uses java.awt.Font objects to render
images. The application will run in tomcat and that is where I have
done development. When I first tried to run the application on a
Linux box with Tomcat 5.0.25 I got the following error:
java.lang.NoClassDefFoundError
at com.words2walls.customquote.CustomQuote.getQuoteFontName(Unknown
Source)
at com.words2walls.webapp.filters.SessionQuoteFilter.doFilter(Unknown
Source)
Here is the code call that throws the error:
public String getQuoteFontName() {
return QuoteFontType.getInstance(this.quoteFontCode).toString();
}
And the class that is being called:
/*

}
/** Creates a new instance of QuoteFontType */
private QuoteFontType(int code, String fontName, String filename) {
// create a font from the font file
try {
File fontFile = new File (pathToWebapp+pathToPackage+filename);
FileInputStream fis = new FileInputStream(fontFile);
font = Font.createFont(Font.TRUETYPE_FONT, fis);
} catch (Exception e) {
throw new FontNotFoundException(e);
}
// set member variables
this.font = font;
this.fontCode = code;
this.fontName = fontName;
}
public String toString() {
return fontName;
}
public Integer toInteger() {
return new Integer(fontCode);
}
public static QuoteFontType getInstance(int code) {
return (QuoteFontType) INSTANCES.get(new Integer(code));
}
public Font getFont() {
return font;
}
}
After some googling I found that if I set an environment variable
JAVA_OPTS=-Djava.awt.headless=true that this error would go away.
I'm not sure why this is the case, but it worked.
I am now trying to test the application on a windows machine with
Tomcat 5.0.30 and I get the same error. I have set a Windows XP
environment variable the same as mentioned above. I have also added
the option to the Java tab of the Tomcat monitor under Java Options:.
What is the cause of this error? Is there some way that I can make it
work on both Windows and Linux? Thanks in advance.

Re: All threads (250) are currently busy
I don't know what kind of application you are running, but most likely you have a resource leak; Do a thread dump and see what your threads are waiting for. Most likely they are just in wait state and no CPU usage. It could be cause by lots of things. One problem could be using jdbc and not closing your connection or returning it to your pool. For testing reduce your resource limit, don't increase it (reduce Max thread, and connection pool). This would cause system hangs faster. Send a SIGQUIT signal to VM and look at state of your threads and its location (don't post your thread dump!)

Increase maxThreads (250) or check the servlet status We are running tomcat 5.5.7 on jdk1.5.0_02 under Redhat Linux Fedora Core 2 against an Oracle9 DB. I have seen various posts to this with suggestions including setting Linux threads with LD_ASSUME_KERNEL (tried but problem still exists) and setting connection timeout in server.xml from 0 to 6 (but ours is set at 2 already). And we have already upgraded to latest Tomcat and JRE to no avail. Despite reviewing the mailing list over the past 18 to 24 months, i am none the wiser. The problem started around the time we deployed the code onto a new server running a later Linux version but this could be a red herring and I suspect it is a database connection issue. Has anyone got any ideas? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: All threads (250) are currently busy
It doesn't matter what platform your running on. On linux you can use kill -s SIGQUIT pid on window box if you have cygwin you can do the same and if you do not just do a google search and there are lots of C code that does that, you can look at signal.h or sites like http://www.csl.mtu.edu/cs4411.ck/www/NOTES/signal/kill.html has actual code for you. I haven't tried their code, but I used to have one myself. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat memory alert (UNCLASSIFIED)
You can add these two options to your VM and monitor /tmp/gcOutput log file -verbose:gc -Xloggc:/tmp/gcOutput , or you can add a timer MBean to your server to ping your VM. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
