Re: please help!!! basic problem with tomcat 3.2.3 / win98
Hi, Am a new user in this mailing list. This is what I am doing : Storing data in Servlet Context and Page Context seperately. Issues: 1. Can I access page context from inside Servlets. 2. If i go for clustering of ServletEngine on a Single WebServer. WIll I have mutiple copies of Servlet Context or a Single Copy shared by all. And the same for PageContext. 3. If I go clustering on different WebServers then what will be the case for point 2 problem. As I do to store data in a common place so that it can be accessed by All Servlets as well JSP in case of MultipleInstances of ServletEngine or if it is a SingleInstance. Thanks Pawan

RE: Konqueror
Yes, I've found the same thing in konqueror - it seems to have an odd way of dealing with cookies, flaky at best, but I havn't looked into it in any detail. I also find that when I redirect back to page showing the results of a db update I need to refresh the page before I can see the updates, which isn't necessary with IE or netscrape. I'm not entirely sure what you're after, but have you looked at the getServletContext() method?

Sharing Authorization Between TC4 + Apache
I am currently working on a project where users log into a Tomcat servlet-based system, which does numerous wonderful things :) However, one additional thing I would like to implement is to allow users authorized through the servlets (using sessions etc.) to be also authorized for various apache secure pages. There are numerous reasons why those pages must remain on Apache and I haven't got TC4 and Apache linked as yet (not sure if it's widely done as yet). Is there any way of passing htpasswd authorization from a servlet to Apache or any clever way of doing it? Essentially, I would like the htpasswd dialogs to be transparent if the correct person is logged into the servlet system. Any ideas please? Dave

Hi everybody, I would like to know how to configure TomCat 4B7 to see all the debug message on console and especially the request/response received and send by TomCat. It will be usefull for me to understand how HTTP protocol work. Thanks Stephane

Where do you have the jdbc2_0-stdext.jar file? I'm betting that it needs
to be in $CATALINA_HOME/common/lib only for this to work -- because JAR
files here are on the class loading path for both Catalina internal
classes and web application classes.

Hello all,
I read the great message Craig McClanahan posted in the archives (from
Aug 4) about how to setup and use a tomcat 4 datasource. All
has seemed
to go pretty well, but I'm having a funny problem, which I'm
not sure is a
Tyrex problem, a Tomcat 4 problem or a Java education problem
on my part
:). (I'm using Tomcat 4 beta 7)
When I try to get a DataSource from JNDI, I can retrieve a
reference just
fine. The problem is that I am having trouble casting it to a
javax.sql.DataSource. It returns an instance of
tyrex.jdbc.xa.EnabledDataSource. If I try to cast to
javax.sql.DataSource, I get a ClassCastException from the server. I
looked up this class in the Tyrex API docs, and it does in fact
implement
javax.sql.DataSource -- I think I should be able to cast to it
because of
that. If I work with the tyrex implementation directly, all is
ok (i.e.,
calling tyrex.jdbc.xa.EnabledDataSource.getConnection()), but I
obviously
won't want to care about the particular implementation in this case.
If it helps, here is the code I'm trying to use:
--
ctx = new InitialContext();
ds = (DataSource)ctx.lookup(java:comp/env/jdbc/lis_ds);
--
That failed, so I added this for debugging:
--
Object o = ctx.lookup(java:comp/env/jdbc/lis_ds);
if (o == null) {
System.out.println(looked up a null object);
} else {
System.out.println(o is of type: + o.getClass().getName()); //--
prints tyrex.jdbc.xa.EnabledDataSource
}
--
The exceptions I get are like this:
--
java.lang.ClassCastException: tyrex.jdbc.xa.EnabledDataSource

As far as I can tell (I'm working on a similar problem at the moment): o the loader for the jvm examines the C locale and sets file.encoding o on solaris 2.6, in the C locale (LANG unset), the file encoding is latin 1 (ISO8859-1). o on solaris 2.7, in the C locale, the file encoding is ascii (646), but in the en_US (LANG=en_US) the file encoding is ISO8859-1. or at least those are the results I get on the 1.2 jvm's I have loaded. If I had to guess, the story is something like a C locale implies an encoding, a Java locale does not (makes sense everything is UCS-16 anyway), you can spec an encoding for Java to use when transcoding external multi-byte to widechar (look at InputStreamReader) but it defaults based on the external C locale (ie how it expects your files to work). Figuring out the default encoding difference will at least explain the difference between the boxes (assuming that's what it is). That still leaves figuring out how it comes into play. But it's a start. you gave me the right hint. After I defined LANG=en_US in tomcat.sh all works fine. Strange enough, I had a similar problem regarding the representation of amounts of money on Solaris 8 with JVM 1.3.0_02. There the definition of LC_MONETARY in tomcat.sh didn't work but an additional -Duser.language=de to the JVM command line did it. Thanks a lot. Frank

RE: Possible to return multiple responses/pages for a request?
This is an unproven browser side solution which involves JavaScript and framesets... 1. The page that submits to the long running servlet should consists of a frame set. The one frame is visible and displays the page that allows the user to input the data. The second frame is invisible and contains a form containing duplicate form variables. 2. The submit button on the user input page does the following: 1. Copies the contents of its form variables to the hidden frame's form variables. 2. Redirects the current frame to your Processing your request, please wait...page. 3. Your Processing your request, please wait... contains an onload function which calls a JavaScript function in the hidden frame telling the hidden frame to submit itself to your servlet, targeting either the visible frame or top to replace the frameset completely. I have not tried this, but I think it should work. If you try it, please let me know if it works. Jim Urban Product Manager Netsteps Inc. Suite 505E 1 Pierce Pl.

Re: Graphics with jsp
Hi, One of the solutions (though not very elegant) is to create the graph dynamically by dynamically generating html in a jsp/servlet after fetching the data from the database. You create the requisite no. of html tags (td and tr)and fill then up with colour. Of course this wouldnt help in case of complex graphs, and if you feel that your or the programmers time can be utilized doing something else more productive. The advantage is that it is useful for simple graphs and is free. Regards Nitin Goyal Webrizon eSolutions Pvt.

suppressing white space in jsps
Is there any way to suppress the whitespace that is output by jsp's in Tomcat/Catalina? I have a simple jsp that generates a .csv, and sets the HTTP headers so that it opens in Excel (intranet app). Even with cramming all the jsp intro stuff on one line, I still end up with one blank line as the first line of output. (actually, one newline code). I know that jasper must be converting every newline in the source .jsp to something like println(\n) in the servlet --- that's what I'd like to turn off (selectively) Is this possible? -jason

AW: starting tomcat from tcl
the solution of the problem (in case anybody is interested): CLASSPATH contained jsdk.jar which contained an old version of the ServletException class.

Re: behaviour of getRequestDispatcher for bogus URLs
What should the behaviour be if I call forward() on a RequestDispatcher that (I know) doesn't exist? (Ya, ya, I get the same behaviour as if I didn't know it doesn't exist :-) For example: getServletContext(). getRequestDispatcher(/I_know_this_page_doesnt_exist.html). forward(request, response); I would expect a NullPointerException but that is not what I get. Instead, I see the following output in my browser window (Mozilla 0.92): htmlbody/body/html Or The document contains no data from Netscape 4.7. And, if I use lwp-request I get a 404 error which is reasonable. What should I get? The javadoc for ServletContext says: This method returns null if the ServletContext cannot return a RequestDispatcher for any reason. But I'm not sure what that reason might be given that a bogus URL doesn't seem to do it. Also, the spec doesn't say anything about bad URLs. I *like* the interesting questions :-). The answer depends on a precise understanding of what the spec says. It says that you get a RequestDispatcher for the servlet that will handle the request URI you specify. Ok, in the Dispatching Requests chapter (8) in Sevlet Spec v2.3 PFD 2, it says If no servlet can be resolved based on the given path, a RequestDispatcher is provided that returns the content for that path. and that content is a 404 error. In Tomcat, there is an implicit mapping like this: servlet-mapping servlet-name default /servlet-name url-pattern / url-pattern /servlet-mapping which says, in effect, the 'default' servlet handles *all* requests that are not mapped to anything else. Thus, there will never be a URL for which you cannot return a RequestDispatcher. So that is an implementation detail. I.E. that is how catalina implements the spec. Why does the spec allow for getRequestDispatcher to return null? Now that I've asked that, I don't actually remember seeing in the spec that is can return null. Oh yeah, in the Duke Bookstore example from Sun, they say in the source code that getRequestDispatcher() can return null. When you actually try to RequestDispatcher.forward() to this, you will get a 404 error, just as if you'd asked for it directly. Thanks, Kevin. Craig Kevin. Do You Yahoo!?

JSP - postService() or aequivalent ?
Hi,
Our Application architecture requires that we enclose method calls (in a
JSP-File) with
// create Environment tied to the current Thread
Environment.createNewEnvironment();
try {
... do work ...
} catch {
// Removes Environment
Environment.cleanup();
}
The environment is a object with manages e.g. the db-connection and
information about the current user. It is tied to the thread (using the
current thread as key in an hashtable).
We don't want to burden this on the developer (very error prone!), so
we're looking for a chance to do it transparent for him. Maybe this
could be done with an RequestInterceptor, but that is a tomcat-specific
solution, isn't it?
Any ideas ?

Re: Graphics with jsp
At 02:54 PM 22/08/01, you wrote:
Hi,
One of the solutions (though not very elegant) is to create the graph
dynamically by dynamically generating html in a jsp/servlet after fetching the
data from the database. You create the requisite no. of html tags (td and
tr)and fill then up with colour. Of course this wouldnt help in case of
complex
graphs, and if you feel that your or the programmers time can be utilized
doing
something else more productive. The advantage is that it is useful for simple
graphs and is free.
Which interestingly was in the JDC Tech Tips I received yesterday... the
relevant bit is cut 'n pasted below. I've included the archive links in
case you're interested:
DELIVERING DYNAMIC IMAGES FROM JAVASERVER PAGES (JSP) TECHNOLOGY
Have you ever wanted to deliver dynamically-generated images from
your JSP pages (or servlets)? This tip shows you how. To run the
code in this tip, you need Tomcat or another JSP 1.1-enabled web
server. You can download Tomcat from the Jakarta Project page at
http://jakarta.apache.org/tomcat.
When a web page is delivered with a MIME type of image/jpeg (or
one of the other image formats), your browser treats the response
as an image. The browser then displays the image, either as part
of a larger web page or on its own. To set up the MIME type for
your JSP pages, you need to set the contentType attribute of the
page directive in the .jsp file for the specific page:
%@ page contentType=image/jpeg ... %
Then you need to create a BufferedImage to draw on for your
dynamic image:
BufferedImage image = new BufferedImage(width,
height, BufferedImage.TYPE_INT_RGB);
After you create the BufferedImage, you need to get a graphics
context to draw with, either a Graphics or Graphics2D object will
do:
Graphics g = image.getGraphics();
// or
Graphics2d g2d = image.createGraphics();
From here, you can draw the image content. Drawing to the
graphics context draws to the BufferedImage. Initially, the
entire image is black, so it's a good idea to fill the image with
the desired background color. Then, when you are finished drawing,
you need to dispose of the context:
g.dispose();
// or
g2d.dispose();
Once the image is completely drawn, you send the image back in
the response. You can use the JPEGImageEncoder class of the
non-standard com.sun.image.codec.jpeg package to encode the
image. Or, if you use the Java 2 SDK, Standard Edition, v 1.4
Beta, you can use the standard ImageIO class. There is one tricky
part of using the JPEGImageEncoder. You must fetch the
ServletOutputStream from the ServletResponse (response object),
and not use the implicit JSP output variable out.
ServletOutputStream sos = response.getOutputStream();
JPEGImageEncoder encoder =
JPEGCodec.createJPEGEncoder(sos);
encoder.encode(image);
// or
ImageIO.write(image, JPEG, out);
Here's a complete example that picks one option from all the
choices (for example, g.dispose(); versus g2d.dispose();).
The example uses the Graphics object to draw a random
polygon. The image is drawn back through the JPEGImageEncoder.
Feel free to play with the number of points in the polygon to get
more complex shapes, in other words, shapes with more points and
edges.
To run this example, place the JSP code from %@ to the
last % in a file named image.jsp. Place the image.jsp file in
a directory that your web server can find. In the case of Tomcat,
this is the ROOT directory, under the webapps directory, beneath
the Tomcat installation directory. To start Tomcat, you need to
run the startup script (startup.bat or startup.sh depending upon
your platform) in the bin directory under the Tomcat installation
directory. Make sure you have the JAVA_HOME environment variable
set to the root level of your Java 2 SDK installation, for
example, C:\jdk1.2.2. Once the file is in the appropriate
directory and Tomcat is running, you can load the dynamic image
generating JSP file with http://localhost:8080/image.jsp.
%@ page contentType=image/jpeg
import=java.awt.*,java.awt.image.*,
com.sun.image.codec.jpeg.*,java.util.*
%
%
// Create image
int width=200, height=200;
BufferedImage image = new BufferedImage(width,
height, BufferedImage.TYPE_INT_RGB);
// Get drawing context
Graphics g = image.getGraphics();
// Fill background
g.setColor(Color.white);
g.fillRect(0, 0, width, height);
// Create random polygon

Re: ldap authentication with tomcat
I think JNDIRealm will do this. However, it seems to be a pretty newly added feature and as far as I can tell, it isn't documented very well. I've been wondering the same thing. If you figure it out, please let me know. You might want to do a search of the mail list archives. I saw a few messages about it in there. However, it looked like it was about a 3rd party add-on that did it. I'm pretty sure the functionality now exists in it natively. I think it's configured similar to JDBCRealm in server.xml. So, I've been thinking that I might try to figure that out first, since, it seems to be better documented.

Re:RE: tomcat 4 datasource Oracle help
I asked the question twice on this list and received no responses. I assume this
means noone has been successful doing this correctly. Since I couldn't wait any
longer, I wrote a temporary solution that reads the properties directly and
allocates connections explicitly using the DriverManager.
Here's the code I ended up using to retrieve the DataSource properties. You can
use it as a temporary solution until someone responds to the correct way to
successfully instantiate the Oracle DataSource. I didn't include the
DBServletDataSourceSpec class here since it is not important to understanding
the implementation workaround.

multiple tomcats one config - hi load
Hi everybody, i have a question regarding multiple tomcats. We are using HPUX 11 apache 1.3.20 and tomcat 3.2.3 We have 4 tomcats running using each his own server.xml all other config files are the same. To achive this I added three new workers in worker.properties and am using them in httpd.conf to direct requests to the different tomcats/jvms This works. The problem is that I have a very high load on the machine without anyone accessing the servlets. I understand that there is a high overhead (threadwise) compared to just one tomcat (additionally we are using connection pools for oracle access). Is this the reason or am I overlooking something important (like resources for four tomcats are used by every single tomcat because of several workers ...) Please advice Thanks a lot gruss stefan

Overriding jar files in /tomcat/lib
Hi all, I'm running Tomcat 3.2.1 on Suse Linux 7.0 with JDK 1.3. I have an application that runs with xalan-j_2_0_1 and Xerces-J-1.4.0 which support namespaces, and the only way I can get tomcat to pick them up seems to be by removing jaxp.jar and parser.jar and putting the new xalan and xerces jar files (as well as the xalanj1compat.jar) in the /tomcat/lib/.. directory in their place. I have tried putting them in my applications /lib directory as per the spec, but tomcat only seems to pick up the other jars (jdbc drivers etc...) and I always get an exception from tomcat saying that namespaces are not supported etc... I have also tried adding them to my custom worker.properties file classpath _before_ the standard includes, but that has not brought success either. Am I missing something simple here, or is there an elegant way to do this? cheers Stu

Re: Solaris Problem
Roy, I am mixed success with Tomcat and Solaris. In all cases, we're running Solaris 2.7 (properly patched), JDK 1.3.1, and Tomcat 3.2.3 with mod_jk. We've two applications. Fortunately, our web product (a thin-client document imaging and workflow application) runs like a top. My other application--a smaller, custom job--tends to hang on Solaris with Tomcat and I'm not sure why (works fine on Linux with Tomcat and on Solaris with WebLogic).

multiple context paths pointing to the same doc base?
Hi there, May be somebody can give me a quick answer with regards to T3.2.2.

How to flush apache response buffer?
Hello - We created a chat webapplication using Servlets and JSP. Under Tomcat as stand alone (via port 8080) the method ServletResponse.flushBuffer(); works fine. So we can react directly to incoming messages and internal events by putting the output to the response on this way. But now we have to set up the application on an apache websever (via port 80) using the connector to tomcat. The problem is that apache buffers its output by itself. So the simple flushing of the ServletResponse isn't enough. Can someone help us, how to flush the response buffer of apache? - Is there any setting in the configuration files? (like httpd.conf, server.xml, etc.) Thanks for all help. Matthias
Re: behaviour of getRequestDispatcher for bogus URLs
See embedded answers below. On Wed, 22 Aug 2001, Kevin HaleBoyes wrote: What should the behaviour be if I call forward() on a RequestDispatcher that (I know) doesn't exist? (Ya, ya, I get the same behaviour as if I didn't know it doesn't exist :-) For example: getServletContext(). getRequestDispatcher(/I_know_this_page_doesnt_exist.html). forward(request, response); I would expect a NullPointerException but that is not what I get. Instead, I see the following output in my browser window (Mozilla 0.92): htmlbody/body/html Or The document contains no data from Netscape 4.7. And, if I use lwp-request I get a 404 error which is reasonable. What should I get? The javadoc for ServletContext says: This method returns null if the ServletContext cannot return a RequestDispatcher for any reason. But I'm not sure what that reason might be given that a bogus URL doesn't seem to do it. Also, the spec doesn't say anything about bad URLs. I *like* the interesting questions :-). The answer depends on a precise understanding of what the spec says. It says that you get a RequestDispatcher for the servlet that will handle the request URI you specify. Ok, in the Dispatching Requests chapter (8) in Sevlet Spec v2.3 PFD 2, it says If no servlet can be resolved based on the given path, a RequestDispatcher is provided that returns the content for that path. and that content is a 404 error. In Tomcat, there is an implicit mapping like this: servlet-mapping servlet-name default /servlet-name url-pattern / url-pattern /servlet-mapping which says, in effect, the 'default' servlet handles *all* requests that are not mapped to anything else. Thus, there will never be a URL for which you cannot return a RequestDispatcher. So that is an implementation detail. I.E. that is how catalina implements the spec. Why does the spec allow for getRequestDispatcher to return null? Because not every servlet container uses this technique for serving static content. In fact, serving static content is *not* required by the spec at all :-). So, even serving HTML files is a feature of Tomcat -- which you can turn off, if you wish, by removing the servlet mapping for the default servlet. Then, Tomcat will indeed return null. Now that I've asked that, I don't actually remember seeing in the spec that is can return null. Oh yeah, in the Duke Bookstore example from Sun, they say in the source code that getRequestDispatcher() can return null. It's in the Javadocs for ServletContext.getRequestDispatcher(). In 2.3, the Javadocs are part of the spec document itself, so they are just as official as the rest of the text. You can get the spec at: http://java.sun.com/products/servlet/download.html When you actually try to RequestDispatcher.forward() to this, you will get a 404 error, just as if you'd asked for it directly. Thanks, Kevin. Craig Kevin. Craig
Re: Sharing Authorization Between TC4 + Apache
On Wed, 22 Aug 2001, David Molloy wrote: I am currently working on a project where users log into a Tomcat servlet-based system, which does numerous wonderful things :) However, one additional thing I would like to implement is to allow users authorized through the servlets (using sessions etc.) to be also authorized for various apache secure pages. There are numerous reasons why those pages must remain on Apache and I haven't got TC4 and Apache linked as yet (not sure if it's widely done as yet). Is there any way of passing htpasswd authorization from a servlet to Apache or any clever way of doing it? Essentially, I would like the htpasswd dialogs to be transparent if the correct person is logged into the servlet system. Any ideas please? To physically share the databases of username information, you would have to write a TC$ Realm implementation that read the corresponding password files (.htpasswd or whatever) that Apache is reading. However, you would still need to set up your security constraints with URL patterns that map how Apache applies protections hierarchically. I will let Pier talk about the technology issues of sharing authentication information at runtime between Tomcat and Apache, but here's one completely stand alone approach that should work: * Use BASIC authentication in both Apache and Tomcat * Use the same Realm Name strings in both Apache and Tomcat * Make sure that the username, password, and group (for servlets, this is the same as role) information is identical in both user databases. The reason this works is that the username and password are sent (by the browser) along with every request that has a matching realm name on the same host. Thus, the user will authenticate themselves the first time that they run into a protected resource on either side, and the other side will automatically recognize it. Dave Craig

We don't want to burden this on the developer (very error prone!), so
we're looking for a chance to do it transparent for him. Maybe this
could be done with an RequestInterceptor, but that is a tomcat-specific
solution, isn't it?
Yes, it is.
Any ideas ?
In JSP 1.2, there is a new variant of custom tags that can implement an
interface called TryCatchFinally (no, we couldn't ever think of a better
name for it :-). Given this, you can ensure that the finally clause
*always* gets executed, even if the application code throws an exception.
To use this, you could write a custom tag that implemented
TryCatchFinally, and enclose the do work part in the body:
mytags:environment
... do work ...
/mytags:environment
Essentially, you would embed the Envorinment.createNewEnvironment()
stuff in the doStart() method of this tag, and the Environment.cleanup()
thing in the doFinally() method.
Of course, IMHO, you would be *substantially* better off to dispense with
performing business logic inside JSP pages in the first place, and use an
MVC architecture like Struts http://jakarta.apache.org/struts, but that
is a completely separate discussion.

I'm receiving this error often: $2001-08-21 15:56:29 - ContextManager: SocketException reading request, ignored - java.net.SocketException: Connection refused: Connection refused at java.net.SocketInputStream.socketRead(Native Method) at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at org.apache.tomcat.service.http.HttpRequestAdapter.doRead(HttpRequestAdapter. java:115) at org.apache.tomcat.core.BufferedServletInputStream.doRead(BufferedServletInpu tStream.java:106) at org.apache.tomcat.core.BufferedServletInputStream.read(BufferedServletInputS tream.java:128) at javax.servlet.ServletInputStream.readLine(ServletInputStream.java:138) at org.apache.tomcat.service.http.HttpRequestAdapter.readNextRequest(HttpReques tAdapter.java:129) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpC onnectionHandler.java:198) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:501) at java.lang.Thread.run(Unknown Source) 2. When I try to shutdown Tomcat with tomcat.sh it never dies and I end up having to use the kill command. Here is the environment: HP-UX 11.00 JDK 1.3 Tomcat 3.2.3 Any and all replies are welcomed Thanks in advance, Dan

Although it is possible to use mod_jk with Tomcat 4, you might also investigate using mod_webapp instead. With that, you can totally dispense with auto-generated files, because deploying individual web applications comes down to adding a single line to httpd.conf. All the rest of the configuration information is read from the web.xml file, and automatically used to configure Apache. Precompiled versions of mod_webapp are available for several platforms in the same directory where you downloaded Tomcat 4.0-beta-7 from: http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0-b7/ Sources are available as well, if you need to build it for your platform. thank you !
