RE: Deploying an XSLT filter in Tomcat 4.0
My current web.xml looks like (excluding prolog) It's pretty cool that tomcat's web.xml lets you code in prolog, although I think that will fail the sun standards test :-) -Original Message- From: Martin Coxall [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 21, 2001 10:56 PM To: [EMAIL PROTECTED] Subject: Deploying an XSLT filter in Tomcat 4.0 Does anybody know the current level of support for filters in Tomcat 4.0? I have written a small filter to take the XML output from one of our servlets, and then dependent on a parameter in the ServletRequest, use Xalan to transform the XML to HTML, WML or VoxML as appropriate. Unfortunately, I am completely unable to make Tomcat 4.0 chain the filter to the Servlet, so all I am getting is raw XML rather than HTML etc. My current web.xml looks like (excluding prolog) web-app servlet servlet-nameEchoServlet/servlet-name servlet-classuk.co.itouch.EchoServlet/servlet-class /servlet filter filter-nameEchoFilter/filter-name filter-classuk.co.itouch.EchoFilter/filter-class /filter filter-mapping servlet-nameEchoServlet/servlet-name filter-nameEchoFilter/filter-name /filter-mapping /web-app What am I doing wrong? How do I make Tomcat chain the filter to a servlet? Do I have to invoke the servlet in a special way? Thanks Martin
forward() question
I have some code that looks something like this;
RequestDispatcher rd =
_req.getRequestDispatcher(/invalid.jsp);
try {
rd.forward(_req, _resp);
} catch ( ServletException e ) {
} catch ( java.io.IOException e ) {
}
The question is does control ever continue after the forward() method call?
It would seem sensible that it didn't
if you viewed forward as, I no longer wan't this page, but another one
instead.
My problem is that the above code is in a bean, which does an isValid user
check and forwards to a page if they are not. After the bean access I have
regular pages which are only mean to be displayed if the user is valid.
Like this;
jsp:useBean id=userChk class=package.UserValid/
jsp:setProperty name=userChk property=UserName value=auser/
jsp:setProperty name=userChk property=UserPass value=apass/
% userChk.setPageInfo(request, response); %
jsp:getProperty name=userChk property=IsValid/
body bgcolor=#7080D0 link=#00FF00 alink=#00 vlink=#00
font size=+1 color=#D0F0F0
p
Show this if user is valid
/p
/body
What actually happens is the invalid page is shown, with the additional
Show if user is valid html appended to the end.
What can I do? I'd really like the forward to actually forward, not act like
include.

As the InputStream has no concept of file paths there is no easy way to
determine where
in the CLASSPATH it was loaded from. CLASSPATH search order is actually
undefined allthough it tends to left to right. The only way I can think of

If we try to re-submit the request just few seconds after, clicking the same submit button ... it will work. Sometimes it will work first time too. Actually it will reject request maybe one out of three times, the slower the connection (I think) the more likely rejection is. Ok, these are the details. The application is a shopping cart and when user is submitting items to the cart, there is no problems. In this case we submit to regular http (not secure), and in the request there is only couple of values. After that, there is a page with the credit card and order information with about 20 or so fields, now this is https protocol we submit to. This is when the problem occurs, this page with 20 or so values, and using https will reject randomly. If you try to submit again once you were rejected, it will go through... This does not happen with netscape at ALL, but with Internet Explorer only. The .jsp that request is submitted to reads those 20 properties into the bean, using property * Also, if we run tomcat only, locally (without apache), so if we submit to localhost:8080, this will not happen. This happens only when we submit over the net using apache, but then again we do not use https when using localhost.

Its one of those things that is, and isn't, very easy. In its most simplistic form, running a CGI is as easy as calling exec. Passing parameters specificed by GET are set as enviornment parameters, which exec supports passing. Pasing POST data is as easy as connecting the CGI's input stream to the servlet's input stream. The HTML output is also just as simple. The real difficulty comes in when the CGI expects to have all of the regular machine's environment variables set (i.e. PATH, CLASSPATH, LD_LIBRARY_PATH, USER, etc). Setting them isn't the problem, getting them is, as Java has no way to read these.

A further evidence which let believe that the spec 2.2 and 2.3 are fully HTTP 1.1 compliant is the following statement found in the introduction of the text: The following Internet Specifications provide relevant information to the development and implementation of the Servlet API and engines which support the Servlet API: · RFC 1630 Uniform Resource Identifiers (URI) · RFC 1738 Uniform Resource Locators (URL) · RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax · RFC 1808 Relative Uniform Resource Locators · RFC 1945 Hypertext Transfer Protocol (HTTP/1.0) · RFC 2045 MIME Part One: Format of Internet Message Bodies · RFC 2046 MIME Part Two: Media Types · RFC 2047 MIME Part Three: Message Header Extensions for non-ASCII text · RFC 2048 MIME Part Four: Registration Procedures · RFC 2049 MIME Part Five: Conformance Criteria and Examples · RFC 2109 HTTP State Management Mechanism · RFC 2145 Use and Interpretation of HTTP Version Numbers · RFC 2324 Hypertext Coffee Pot Control Protocol (HTCPCP/1.0)1 · RFC 2616 Hypertext Transfer Protocol (HTTP/1.1) · RFC 2617 HTTP Authentication: Basic and Digest Authentication As you certainly know, RFC 2616 relies upon RFC 1867 for FORM handling even though RFC 1867 is still in "Experimental" status. I strongly advice either to modify the servlet spec and make support for RFC 2616 and RFC 1867 complete, or to write more clearly that this is not the case. Ideally, it would be very useful if deviations of the spec from those RFC be described in detail. I stumbled across this problem when trying to submit a POST with enctype="multipart-form/data" to Tomcat 3.1 and Tomcat 3.2.1 and got always nulls. Then I looked in the source and found that the javax... returns NULL in case that the submitted POST contains data but the content type not be= "application-xxx-www-form-urlencoded". According to the specs, "If any of the getParameter family of methods is not called, or not all of the above conditions are met, the post data must remain available for the servlet to read via the request#8217;s input stream." but unfortunately that is not the case since the javax.. implementation returns null as result of the doPost with the enctype="multipart-form/data" The only way to handle that problem (and still remain "pure Java") is currently to extend the HttpServlet with a doPost which supports also enctype="multipart-form/data" such as done by Jason in his classes (http://www.servlets.com/resources/com.oreilly.servlet/index.html) however one would normally expect such functionality to be provided by *any* servlet implementation and for sure by the "servlet standard" ! As myself, several hundreds of other developers are hampered by this fact as one can easily find by searching in the archives of the mailing lists for example at technet.oracle.com in the XML discussion group, or in tomcat mailing lists.

RE: Hi Ho - Problem with ServletOutputStream in Tomcat
This is true, I wrote a multipart/form-data parser and the only character
set which preserved
binary data was ISO-8859-1. Conversions between bytes and characters only
work with this encType, your input and output should both use this if you
use characters to store binary data.
Output streams are supposed to output bytes, the print in the
ServletOutputStream method converts a char to a byte array, you'd be better
off using the write(byte[] b) method of the base OutputStream class.

RE: Need help! :( (XALAN CONFIG )
Hi
This question comes up alot on this list. The fix is to put your xml parser
before the tomcat one in the CLASSPATH. ie xalan.jar;xerces.jar;xml.jar
This will avoid the less functional classes in xml.jar being used when you
really want the newer classes. You can make the change in tomcat.[sh|bat]
for tomcat 4.0 In 4.0 I think the WEB-INF/lib is
automatcally searched b4 the system classpath, so no problems like this.
If you want more detail search the list archive.

Subject: Need help! :( (XALAN CONFIG )
Hello
We are trying to configure Tomcat to work with Xalan (the XSLT engine).
We have set up the servlet (XSLT.class) in the webapps directory ie
D:\tomcat\webapps\faisal\WEB-INF\Classes\XSLT.class
we have also configured the 'web.xml' in
D:\tomcat\webapps\faisal\WEB-INF
this file looks like :
- web.xml
?xml version="1.0" encoding="ISO-8859-1"?
!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2.2.dtd"

We can run simple example servlets however, when using the
XALAN API, we keep getting the following errors:

The servlet compiles ok and the all the Xalan jars are placed in the correct
directories,
however, there seems to be a problem with Tomcat finding the above Xalan API
method call.
We've tried doing many things already and are urgently needing some help.
Here's the simple servlet that we've been working on :

StreamSource(xslFile));
transformer.transform(new StreamSource(xmlFile), new
StreamResult(new File("result.out")))
}

RE: Hi Ho - Problem with ServletOutputStream in Tomcat
You will probably find it's bytes 127dec that are getting mucked up. In the
char/byte conversion the
sign bit seems to do some funny stuff when converted. As a quick test create
a binary file with low value ( 127 ) bytes and see if it transfers ok. You
will need to make sure your reader is using
ISO-8859-1 to fix the problem, or even better dont use character readers at
all.

Betreff: RE: Hi Ho - Problem with ServletOutputStream in Tomcat
This is true, I wrote a multipart/form-data parser and the only character
set which preserved
binary data was ISO-8859-1. Conversions between bytes and characters only
work with this encType, your input and output should both use this if you
use characters to store binary data.
Output streams are supposed to output bytes, the print in the
ServletOutputStream method converts a char to a byte array, you'd be better
off using the write(byte[] b) method of the base OutputStream class.

RE: IllegalAccessError?
Is your Building class and constructor public? I know it sounds basic but
its important to the servlet container.

Subject: IllegalAccessError?
This is most likely a newbie question, so please bear with me.
I have a class of my own, ("Building") which is compiled and placed in my
WEB-INF directory.
Whenever I try to instantiate this class, I receive a IllegalAccessError
error. According to the Java 1.2.2 API docs:
"Thrown if an application attempts to access or modify a field, or to call a
method that it does not have access to.
Normally, this error is caught by the compiler; this error can only occur at
run time if the definition of a class has incompatibly changed."
Which makes sense, but the JSP will die with just this:
Building b = new Building();
When I go into the generated servlet, I can see that it dies on this same
line every time. If I run it like this:
Building b;
b = new Building();
... it will die on the second line.
To see if there's a problem in my Building class I wrote a simple
application which simply takes a dozen Building objects, tosses them into a
LinkedList object, and then prints them out one at a time. It works great as
an application, but this servlet is giving me fits.
Am I doing something wrong? I'm at a loss.

RE: Using a servlet superclass
Well no simple solutions will do exactly what you want. There is nothing
special about the init method in java. It might be nice if the servlet
container promised to walk up the class hierachy calling each init as it
goes but thats not how it works.
But you could;
1.Use the java debugging interface to detect when the method init is being
called in you derived class and call the base class method.
2.Create your own Method object ( bytecode ) and replace the derived classes
init method bytecode ( is this even possible? ) giving
newinit = function() {
call super.init
call oldinit
}
oldinit = derived.init
derived.init = newinit
Okay, these are a bit tounge in cheek :-) Depends how much you don't want to
call super.init() I guess...

Subject: Using a servlet superclass
I have a number of servlets in my application that need to
perform common initialisation, etc. So I was thinking of
creating a superclass that has an init method that does all
of the common work, eg.,
public class SuperServlet extends HttpServlet {
public void init() {
// do common initialisation stuff in here
} // init
} // SuperServlet
Then all the workers servlets would extend SuperServlet
rather than HttpServlet, eg.,
public class WorkerServlet extends SuperServlet {
...
} // WorkerServlet
This seems to be OK, until I implement init in the
WorkerServlet, as the init method in the SuperServlet
does not then get invoked. While I can call super.init()
in the WorkServlet, I want this to be handled automatically
as I can bet on someone forgetting this step, eg.,
public class WorkerServlet extends SuperServlet {
public void init() {
// don't want to have to make this call == super.init();
} // init
...
} // WorkerServlet
Is there any way to implement this ?
