X11 Windows System and Tomcat
This is maybe not a pure Tomcat question, but I am running a servlet on Tomcat which uses javax.swing, to resize jpeg images, but which does not, of course, want to display those images. This throws an exception, due to a bug in the JDK 1.4. The exception is: Exception in thread main java.lang.InternalError: Can't connect to X11 window server using ':0,0' as the value of the DISPLAY variable. at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) at sun.awt.X11GraphicsEnvironment.clinit(11GraphicsEnvironment.java:126) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:130) at java.awt.Toolkit#2.run(Toolket.java:712) at java.security.AccessController.doPrivileged(Native Method) at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:703) at javax.swing.ImageIcon.(init(ImageIcon.java:81) at javax.swing.ImageIcon.init(ImageIcon.java:107) ps aux reveals: /etc/X11/X -auth /var/lib/kdm/authfiles/A:0-0Dqymv Anyone know the command I need to use to solve this, if any? I would prefer not to use a virtual X11 system, or to build a substitute Toolkit for the JDK.

Re: ResultSet
If you want to compare String objects as literals, use the intern() method.

Hi,
For the brave, can anyone guess why with this rather unsociable code:
if ((res.getString(3) == null) || (res.getString(3) == )) {
out.println(tda href=takeDetails.jsp?timeSlot= +
res.getString(2) + myDate= + myDate + + res.getString(2) +
/a/td);
}
if ((res.getString(3) != null) || (res.getString(3) != )) {
out.println(td + res.getString(3)+ + res.getString(2) +
/td);
}
the first condition is NEVER satisfied, even though out.println of
res.getString(3) does not display anything! Ie res.getString(3) IS null,
empty or whatever, but the condition is never satisifed. Quickly again, this
is executed:
if ((res.getString(3) != null) || (res.getString(3) != )) {
out.println(td + res.getString(3)+ + res.getString(2) +
/td);
}
even though - out.println(td + res.getString(3)+ - shows it is
empty (no output)!
Thanks

Re: Development Documents
Hi, Gunnar. I think that this is what JSP itself does already, i.e. return HTML content. So, I am not sure what you are asking. If you don't want to use JSP pages, then don't. I am sure that is not what you wanted to say, so, again, I misunderstood what you are saying. Could you be more specific about what you want? You don' t have to use JSP pages with Tomcat, but then there would be no point in having Tomcat really. At 08:50 PM 2/5/02 +0100, you wrote: Hi!

Re: Multiple URLs/Single IP
Thank you, Bojan. I am going to try that, and will try to figure out a favor for you if it works. My father told me to always pay back ten times: ten times more for a good turn, and ten times more for a bad. Micael At 08:06 AM 2/5/02 +1100, you wrote: Now you have me totally confused :-( I'll tell you what I know, and if that helps you, good. If not, please disregard. The fact that www.aa.com and www.bb.com have the same IP address makes them name based virtual hosts. So, you're telling your TC 3.3.x to be ready to handle things for both www.aa.com and www.bb.com by creating virtual hosts withing it. If you have Tomcat running on the same box, it would usually be connected to Apache via mod_jk and listen to address 127.0.0.1 only. So, I'm not certain how the 'one IP' address plays here at all... Inside each virtual host, you define applications (contexts). So, you can have webapps/aa for www.aa.com and webapps/bb for www.bb.com. That's at least how I run my machines.

I have figured out how to get the different URLs into different Host tags, but so far they all encompass the same webapps or none. I have some further ideas on how to avoid that. We'll see tomorrow.

Multiple URLs/Single IP
How can I map multiple URLs, e.g. www.aa.com and www.bb.com, which are pointed to a single IP address, e.g. 210.34.247.21, to multiple web applications, e.g. webapps/aa and webapps/bb?

CS143
Hi, Greg, I am working late tonight, cannot sleep. So, I thought I would put together a little grading tool for CS143. If you like it, feel free to change it, use it, sell it, whatever. ;-) The way it works is you put the unzipped files in c:\jdk1.3\jre\classes\ and go there on the command line or any IDE tool that runs the java command and run "java cs143.test.Test". A screen will come up and, if you were a student, you would enter "cs143 harry harry" (course, name, password). This will tell the student, if their class implements the tag interface Testable whether or not they pass the test set for their class. You can give the test the class must test prior to them building the classes. The student can keep changing their classes until they get a pass. Each attempt is recording it a log file. I sent a copy to Erika, in case Mark Vanbeek might find it helpful. Hope he can join us Tuesday.

Re: Tomcat4, taglibs, and pageContext.include
I have to say that I personally think whomever made this decision made a
poor decision. I do not, of course, have all the facts and the reasons why
such a decision was made, but it would seem to be too drastic to be
justfied.
The use of templating in tag libraries centers around this sort of code. I
don't have a vote or anything, of course, but, if I did, I certainly would
vote against this. Doesn't this break Struts templating? I don't use
Struts, but do follow that sort of architectural premise.

The reason for this change is a statement in the Javadocs for
PageContext.include() that Tomcat 4 was not previously enforcing:
The current JspWriter out for this JSP is flushed as a
side effect of this call, prior to processing the include.
Ideally, that statement would have been removed from the Javadocs for JSP
1.2, but it wasn't ... and now we are stuck enforcing it. If you look at
the code that Jasper generates for jsp:include, you will see that it
indeed no longer uses the PageContext.include() method in its
implementation.
