byte serving PDF with Tomcat 5.0.27
Hello all, I'm running Tomcat 5.0.27 on Linux, and need to know if this version of Tomcat supports byte serving and how to determine if it's working. If anyone can provide any help, I'd greatly appreciate it! Thank you, Shawn Maceno - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: byte serving PDF with Tomcat 5.0.27
Thanks for the quick reply. I think I need a little more hand-holding on this one, not being the Tomcat genius... Can you provide some kind of example that shows where the content-type setting is and what it needs to be?

RE: Servlet gateway to legacy cgi application
Steve, I've developed servlet-based webapps for several years, I've written servlet filters and implemented many various types of authentication mechanisms, and I've also done request forwarding within an application. I was hoping to implement something similar to request forwarding, but according to Sun, Requests may be forwarded only to components within the same application context root, never between applications. I have to think however that there must be a way to accomplish this. This need has never arisen for me either, so I would not be surprised to find there may be something within the servlet API or within the Tomcat container itself which with I am not familiar. Any thoughts? Thanks, Shawn Quoting Steve Kirk [EMAIL PROTECTED]: I'm not personally aware of anything already built in to TC that specifically handles request, although having said that I haven't really ever had the need for it.

RE: Servlet gateway to legacy cgi application
I initially looked at CGIServlet, but I run the Apache http server, rather than using Tomcat's implementation. I also need to implement my own functionality (primarily for user authentication). But yes, this is close to what I'm after. I'm sure I can roll my own, but it would be nice to find an existing solution. I just googled cgiservlet, and this may yield something useful.

ENCTYPE + SetCharacterEncodingFilter = no go joe for Tomcat 5.0.28
Hello, When using ENCTYPE=multipart/form-data in a form on a jsp page, text sent ignores the SetCharacterEncodingFilter which is calling request.setCharacterEncoding(UTF-8); I thought about getting parameter values by using String field = request.getParameter(whatever); field=new String(field.getBytes (UTF-8)); Does this seem a reasonable approach or is should the SetCharacterEncodingFilter *really* be setting the charEncoding? I don't want to be creating a new string for every parameter unless necessary. When ENCTYPE is not set, all works as expected. This problem is seen on Tomcat 5.0.28, but not 4.x versions. I understand something changed around 5.0.27 for UTF-8 handeling but am not sure if that is realated. -- Shawn [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

mod_jk hangs
Just yesterday we started running into problems requesting pages on our production website through mod_jk. Previously everything had been working fine for months. Essentially what happens is when you request the page for the first time (doesn't seem to matter what browser you're using) the browser just sits and spins. Then after hitting refresh (Ctrl+R) a couple times it finally comes up. Subsequent visits to the same page continue to work for me in Mozilla but after closing IE and reopening it after a couple more requests it hangs again. In case it helps, the site in question is http://www.atmreports.com. I simply cannot figure out what is going on. I do see many errors in the mod_jk.log, but these had been there before when everything worked fine too: [Wed May 05 09:27:46 2004] [jk_ajp_common.c (1137)]: Error reading reply from tomcat.

This seems to be the most probable cause simply because it happened around the same time, but I just can't understand why or how. 3. Yesterday we rebooted the box to see if that would help. It did. We didn't have any more problems at all that day until this morning we see the problems again.

Re: mod_jk hangs
Looks like the maximum for everyting in my config was 150 so I'll try setting maxSpareThreads for Tomcat to 150 as well. If this is indeed the cause of the problem, any idea why it would just start happening yesterday after months without problem? My only guess is that perhaps we just happened to reach some threshold of traffic yesterday that we never did before. Actually, that may indeed be the case since we usually get a surge of traffic during the beginning of a month.

I suggest rebuilding tomcat with 1.5 beta if you want to run servlets compiled using 1.5 beta. I'm not even sure my suggestion will work, as I haven't tried it myself. There has not been a tomcat release declared to support JDK 1.5 yet, although you're welcome to do building and testing for us ;) The problem I had, I think, is that my method used an Enumeration and under 1.5 enum is a new keyword but jakarta-tomcat-jasper/jasper2/src/share/org/apache/jasper used enum many places as an identifier, as do some classes in org.apache.tomcat.util.compat -- Shawn Happily using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Riaan Oberholzer wrote: This is not a Tomcat issue, but I've tried desperately and could find no answer elsewhere... can someone please tell me how to get Tomcat working with ZoneAlarm (free version) as firewall? In general, it is very advisable to know what a firewall does and how it works before installing one. In general, ZoneAlarm is a (rather simple) packet filter, i.e. a piece of software that examines network packets as they arrive at or depart from the machine and decides on a set of rules to allow or deny them. If you want a so protected machine to run tomcat and access it from beyond the firewall, you need to add a rule that allows requests from external sources directed at port 80 (or whatever you set your tomcat to listen on) on the local machine and also to allow the responses from tomcat to any external host. If you want to use SSL, you will have to allow those request/response-pairs as well. You should, however concider wether you really need a firewall, if your machine is a pure server that does not serve other purposes. In that case, you should just close all ports you don't need. A closed port is no risk and if the listening software has flaws, a firewall wouldn't protect you either.

RE: Regarding Tomcat Start
Vishal: go through the batch file (.bat) and add PAUSE followed by and enter after the tomcat or java command to see their responces. Batch filesare just a series of DOS command made to run in order. It has a GOTO statments and enviorment vars for varibles. The %1 %2 %3 represent the first command line argument, the soncond, and the third. It has if statments. Just follow it throug and add some pauses, that'll cuase it to wiat for you to press a key alowing you to see the error messages. The second command prompt window is called through the first batch fil through the CMD command. Look for the CMD or other betch files and add pauses to those files. It's calling another command prompt to free the one you in when Tomcat starts. This second command prompt is probably giving an error like Port already in use or something else.

Shawn,
I ran into this problem as well when switching from 4.0 to 4.1. I think it
has something to do with 4.1 pooling and re-using tag objects. What I did
in all of my doStartTag(), doAfterBody(), etc... methods was manually call
release() to reset the data in the tags like so:
public int doStartTag() throws JspException
{
try
{
...
}
catch (Exception exception)
{
throw new JspException(exception);
}
finally
{
release();
}
return SKIP_BODY;

Subject: Custom Tag Lib
Tomcat Users:
I've been fighting with some version differences in tom cat wondering why my
app acts severly different on Tomcat 4.1.27 then 4.0.6. It appears that
4.1.27 is not working from my perspective, and have been fighting with it
since monday. None of the books I have touch this subject or ellude to the
problem, and I've seached high and low for solutions.
I'm having a problem working with my custom tag library. The stange part to
this is it appears to work on tomcat 4.0.6 but not on 4.1.27. The library
has a tage called site that extends a base tag, and those tags use other
classes in my data namespace to hit a database.
The tags are returning the proper data in both versions, but in 4.1.27, I
have to reload the contect in the manager for it to register the changes
from the database. I have added some printlns to std out to track what's
going on. In tomcat 4.0.6 they are going through all the code as I would
exspect it to. I have included each of the class files that are called. I
have also included the printouts from both versions of tomcat to clierify
how each version is handling the calls.
The object hiarchey goes as follows:
jPublish.Tags site extends inc_tag.
jPublish.Data.site_manager extends jPublish.Data.manager, managers contain,
load, and fill datas.
jPublish.Data.site_data extends jPublish.Data.data, used for storing data
and tracking updates.

RE: Custom Tag Lib
Mr. Mezick:
From what I'm gathering, the release should not be implimented to reset the
data and classes used by a tag, but only for things like closing files and
db connections? Just to make sure I'm thinking about this properly, the
doStartTag should be treated like the constructor: make sure my data is
setup properly there. The doEndTag should be used for normal completion
without errors.
Does Tomcat impliment object pooling beyon the tags? Are my supporting
classes for the tag pooled?
Thanks to all who have helped me.
Shawn

It would be best if you went a rewrote your tags not to require release
to be called. That change will also bring you in-line with the jsp

Shawn,
I ran into this problem as well when switching from 4.0 to
4.1. I think it
has something to do with 4.1 pooling and re-using tag
objects. What I did
in all of my doStartTag(), doAfterBody(), etc... methods was
manually call
release() to reset the data in the tags like so:
public int doStartTag() throws JspException
{
try
{
...
}
catch (Exception exception)
{
throw new JspException(exception);
}
finally
{
release();
}
return SKIP_BODY;
}
Have a nice day ...

I've been fighting with some version differences in tom cat
wondering why my
app acts severly different on Tomcat 4.1.27 then 4.0.6. It
appears that
4.1.27 is not working from my perspective, and have been
fighting with it
since monday. None of the books I have touch this subject or
ellude to the
problem, and I've seached high and low for solutions.
I'm having a problem working with my custom tag library. The
stange part to
this is it appears to work on tomcat 4.0.6 but not on 4.1.27.
The library
has a tage called site that extends a base tag, and those
tags use other
classes in my data namespace to hit a database.
The tags are returning the proper data in both versions, but
in 4.1.27, I
have to reload the contect in the manager for it to
register the changes
from the database. I have added some printlns to std out to
track what's
going on. In tomcat 4.0.6 they are going through all the
code as I would
exspect it to. I have included each of the class files that
are called. I
have also included the printouts from both versions of tomcat
to clierify
how each version is handling the calls.

jPublish.Data.site_manager extends jPublish.Data.manager,

Hi Shawn,
Actually, I wasn't aware that there was an option to disable it. When I
figured out what was happening, I went ahead and handled it in my code. No
telling how other application servers might handle it. If you're only going
to be deploying on Tomcat, disabling pooling would probably save you some
time, but you still might want to handle it in your code to get better
performance.

DBCP leak ?
As noted in Tomcat docs, A web application has to explicetely close ResultSet's, Statement's, and Connection's. I am using a web app that opens a ResultSet locally (in a method) but it never gets closed (gc'd sometime I presume). Under Oracle, a user is hitting the maximum number of Oracle process and I presume it is a leak. Three questions. 1) must a local ResultSet be explicitely closed to avoid a leak 2) if I use, parameter namelogAbandoned/name valuetrue/value /parameter to log the stack trace, where is that log? Under logs in the usual place for that context. I have to tell someone else where to find the log otherwise would just look for it myself (ie I'm not running Oracle). 3) If only Oracle shows this behavior what could account for that? Diff jvm?

Some JDBC drivers will close the ResultSet for you if you close the
associated Statement, but it sounds like you're probably not doing that
either.
In most places yes. Might drivers also close the ResultSet when using a
preparedStatement.
The ps and connection is always closed. The ResultSet is closed in
most places (and I'll correct where it's not).
I wonder if the Oracle driver wasn't closing it (not that it should be
expected to) and GC wasn't doing it either, hence the leak.
Anyway, thanks for the help.
Will clean up the few rough spots.

Re: JNDI jdbc resources
What about server.xml?
try{
Context ctx2 = new InitialContext();
out.print(Connecting1 : );
Context envCtx2 = (Context)
ctx2.lookup(java:/comp/env/);
out.print(Connecting2 : );
DataSource ds = (DataSource)
envCtx2.lookup(jdbc/DBmultileague);
out.print(Connecting3 : );
if (ds != null) {
out.print(Query1 : );
Connection conn = ds.getConnection();
out.print(Query2 : );
That part worked for me too. Is there an advantage to breaking your
Context into two pieces. Anyway, I tried it like that with no problem.

Please see the cut'n'pastes below. I draw you attention to the fact
that the connection looks good right up to the point where it's used -
like the DataSource object is good (because ds != null is true), yet
the getConnection method throws the often seen Cannot load JDBC driver
class 'null' error.
I know this is very close...what's missing?
I'm sure my jars are in the right place, as a regular forClass approach
in the same webapp works with no problems?

System Monitor accuracy
Is it just me or is the System Monitor unreliable. It shows my cpu at 100% locked there and my system is responding slowly but viewing it bye the process listing (all, my and/or active) gives me nothing using the cpu other than the system monitor and netscape at like 1%). Under windows at least I could find and shut the culprit down.

Re: Require a secure connection
According to http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Security5.html another way would be to specify it in web.xml. ... If you specify CONFIDENTIAL or INTEGRAL as a security constraint, that type of security constraint applies to all requests that match the URL patterns in the Web resource collection, not just to the login dialog. Specify CONFIDENTIAL when the application requires that data be transmitted so as to prevent other entities from observing the contents of the transmission. Specify INTEGRAL when the application requires that the data be sent between client and server in such a way that it cannot be changed in transit. The following example code from a web.xml file shows this setting in context: !-- SECURITY CONSTRAINT -- security-constraint web-resource-collection web-resource-nameWRCollection/web-resource-name url-pattern/index.jsp/url-pattern http-methodGET/http-method /web-resource-collection auth-constraint role-nameuser/role-name /auth-constraint user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint Shawn On Fri, 2003-01-17 at 07:09, neal wrote: Does anyone know how to *require* that a page be accessed only via a secure connection?

Re: Cannot load JDBC driver class 'null'
I had that error too. In my case it had to do with how I configured web.xml and server.xml. I was able to get the example from the docs working but when switching to /root context got mixed up. You aren't using the root context are you? In any case, I would double check again server.xml and web.xml and compare them to the examples. That's where my driver class 'null' problem arose.

I put the source jar instead of the driver binary. Other than that DBCP worked as described in the tomcat documents. Cannot load JDBC driver class null usually means that it couldn't find the jdbc driver that you specified in the server.xml . that is strange cause I have it in $CATALINA_HOME/common/lib And it is exactly the same class that I used when I was using JDBC non-jndi. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Cannot load JDBC driver class 'null'
I had that error too and just reproduced it again to be sure of how I
resolved it.
Let's say the following is a correct entry in server.xml:
Context path=/DBTest docBase=DBTest
debug=5 reloadable=true crossContext=true
but I make a mistake and use
Context path=/dBTest docBase=DBTest
debug=5 reloadable=true crossContext=true
**Notice the D vs d in the context path**
Then I get a Cannot load JDBC driver class 'null' error message
With the root context, where I had my problem, it was confusing because
I needed path=/root and not path=/. Also, the error message is
seemingly unrelated to the actual problem
Anyway, whether or not this is the origin of your error I do not know,
but only know that I got the same message when my context path was
incorrect.

Re: session id's really unique?
Just to confirm, If I send use RequestDispatcher.forward(request, response) and send it to another context, that session will be newly managed under the new context (or by the original context) and therefore there is no risk of duplicate id's. The other issue is to be patched. Shawn Sorry to be paranoid. Can't help it though. On Mon, 2002-12-30 at 23:58, Glenn Olander wrote: You run the risk of getting duplicate session id's. However, across contexts you'll have separate Managers, and therefore different sets of sessions. So, you don't run the risk of one context gaining access to another context's sessions. The risk is the one discussed in the other session id thread where if you get duplicate session id's in the same context.

session id's really unique?
If I use RequestDispatcher.forward(request, response) to another context am I running the risk of session id conflicts? I mean if a session Id is given in one context, another context is restarted and the java.security.SecureRandom is re-initialized for that webapp, then it would seem possible that newly generated sessions in the second context could match the previosly generated session id that was transferred from the first context. I doubt I know as much as many on this list, but that is something that I wondered about. Shawn PS I'm relying on potentially outdated info from a list that was posted in response to this topic. Tomcat 4 uses an instance of java.security.SecureRandom to generate session identifiers for a particular session. The instance is initialized the first time (after Tomcat is started, or after a webapp is restarted) that a session identifier is requested. More seriously, it is *you* as the application developer that is deciding whether or not to execute the RequestDispatcher.include() or RequestDispatcher.forward() call -- it's not the container. It is totally up to *you* to decide whether or not this is allowed, because *you* wrote the app. yes I did but will the sessions tranfer uniquely? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Newbie: Java Mail Problem
David, A troubleshooting idea. I'd isolate this problem by ensuring you can communicate directly via javamail. Try a simple test such as this (in a JSP will work fine)... String host = smtp.verizon.net; String from = [EMAIL PROTECTED]; String to = [EMAIL PROTECTED]; // Get system properties Properties props = System.getProperties(); // Setup mail server props.put(mail.smtp.host, host); // Get session Session mailsession = Session.getDefaultInstance(props, null); // Define message MimeMessage message = new MimeMessage(mailsession); // Set the from address message.setFrom(new InternetAddress(from)); // Set the to address message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Set the subject message.setSubject(Test message); // Set the content message.setText(Testing); // Send message Transport.send(message); If this works.. then I'd suspect something in TC or your config. If it doesn't.. you might want to post this info. to the javamail list. Lots of helpful people over there. Good luck, Shawn. yes, I stopped and restarted the Tomcat service.

OK Re: ClassCastException Conn=dataSource.getConnection();
I see now. Thanks. My confusion was this in server.xml !-- Tomcat Root Context -- !-- Context path= docBase=ROOT debug=0/ -- so I had Context path= docBase=root debug=5 reloadable=true crossContext=true... instead of Context path=/root docBase=root debug=5 reloadable=true crossContext=true... and DataSource dataSource2=(DataSource)ctx.lookup(java:comp/env/jdbc/); instead of DataSource dataSource2=(DataSource)ctx.lookup(java:comp/env/jdbc/root); It's because jdbc is not a datasource, it's a container (or something similar. I have not the time to look it up). In your server.xml/web.xml files you should have a resource that's probably named jdbc/myConnection. Your code should read dataSource2=(DataSource)ctx.lookup( java:comp/env/jdbc/myConnection ); This of course is a guess. Without your config file, it's hard to tell.

DBCP trouble in 4.12
Hello,
Not at all sure if this is my own problem or a bigger issue but I moved
from 4.06 to 4.12 recently and...
The example DBCP given for mysql works fine for me with
mysql-connector-java-2.0.14-bin.jar Thanks for the nice docs!
However, when I move the code to an app I'm trying to move, I get a
Cannot load JDBC driver class 'null' error message. It stems from
Connection conn=dataSource.getConnection(); (see complete snippet
below)
The code was originally in a servlet (and the ds got passed to a bean)
but I moved everything to the bean with the same results.
Connection conn;
// Get the user info from the database
try {
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception(Boom - No Context);
DataSource
dataSource2=(DataSource)ctx.lookup(java:comp/env/jdbc/TestDB);
if(dataSource2 == null )
throw new Exception(Boom - No dataSource);
conn = dataSource2.getConnection();
}
catch (Exception e){throw new SQLException(couldn't get conn
from dataSource2 in employeeBean+e.toString());}
Yes, I recompiled everything after the move and have the driver in the
Catalina_Home/common/lib dir.
TIA,
Shawn

Why would that be?

PS the ds =null error I had earlier was due to not setting up my root

Re: Admin Webapp Problems (WAS: MBean server?)
Okay, this was just dumb on my part. When I installed Tomcat I installed the tomcat-noexamples and tomcat-admin RPM's. However, I noticed that installing Tomcat on a different machine (with examples), the first section in the server.xml file having to do with (believe it or not!) MBean server was not commented out like it was in the noexamples server.xml file. So basically that's all the problem was... if I had looked at server.xml more closely sooner I could have saved myself lots of frustration!

In that version, you will see the following files in common/endorsed: xercesImpl.jar xmlParserAPIs.jar What Bill says it correct, though.

You can either do as he says and go back to using 2.1.0 version or move to the latest jars which contain the fix: http://gump.covalent.net/jars/latest/xml-xerces2/ Otherwise, you could also check the xml commons to grab a xml-commons-api's jar that contains an earlier version of the xerces packages equivalent to the 2.1.0 release. http://xml.apache.org/commons/ Jake Tuesday, November 26, 2002, 10:05:27 AM, you wrote: SW Hi Bill, SW Thanks for the info.

Re: Unable to use getGeneratedKeys() through dbpc
Thanks for the help Steve, here is the code that works...
try {
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds =
(javax.sql.DataSource)ctx.lookup(java:comp/env/jdbc/testDB);
Connection conn = ds.getConnection();
/
BEGIN WORKAROUND
org.apache.commons.dbcp.DelegatingStatement dste =
(org.apache.commons.dbcp.DelegatingStatement)conn.createStatement();
Statement ste = dste.getDelegate();
/
END WORKAROUND
ste.execute(INSERT INTO test (name) VALUES ('test name') );
ResultSet rs = ste.getGeneratedKeys();
rs.next();
out.print(rs.getInt(GENERATED_KEY));
}
catch ( Exception e ) {
out.print(e.getMessage());
e.printStackTrace();
}
The root cause is that dbpc's org.apache.commons.dbcp.DelegatingStatement has a
passthru method for every Statement method as defined by the jdbc2 version of the
Statement Interface.
The DelegatingStatement then simply calls the corresponding Statement method i.e.
public int executeUpdate(String sql) throws SQLException { checkOpen(); return
_stmt.executeUpdate(sql);}
What is needed is the following
public ResultsSet getGeneratedKeys() throws SQLException { checkOpen(); return
_stmt.getGeneratedKeys();}
Of course the more appropriate way of doing it would be to implement the entire jdbc3
version of the Statement interface (as well as the other APIs in jdbc).
Perhaps if I get time I will give it a shot
On Monday 21 October 2002 12:36 pm, [EMAIL PROTECTED] wrote:
Hmmm,
Thats an interesting one, as DelegatingStatement is just a wrapper class
round a regular Statement...And according to the javadocs it inherits the
getGeneratedKeys() from the Statement!
You can get access to the wrapped Statement class with
((DelegatingStatement)ste).getDelegate() - You could maybe try calling the
getGeneratedKeys() on that and see what happens! Its a bit kludgey as you
really shouldnt have to cast the Statement - but javac/jasper will choke if
you dont I think!
Without having a JDBC 3.0 driver to try it out myself thats the best I can
say - hope that helps!

Thanks for the input Steve,
I agree that it SHOULDN'T be dbpc, but it looks as if it is.
Actually the driver does support it quite nicely. Everything works great

Things only break if I retrieve the connection from jndi ( and thus dbpc ).

option ) or create a workaround through sql ( decreased performance
through through additional queries ).

Subject: Unable to use getGeneratedKeys() through dbpc
Hi folks,
It seems to me that dbpc does not support getGeneratedKeys(). If I
understand correctly this is a jdbc v3 call and it is possible that dbpc
will not yet support jdbc3.
I would appreciate any suggestions on alternative pooling mechanisms
that could support this (Or any corrections if I am just being dumb).

after the insert.

Tomcat 4.1.12 unpackWARs
I found some hint of this in past archives, and am wondering if this is a bug or if I am missing something. The following will not unpack a .war file existing in the appBase directory. Tomcat processes will start and then quickly die because according to the log messages generated, the docBase directory doesn't (yet) exist, which is true since the .war didn't first expand: Engine className=org.apache.catalina.connector.warp.WarpEngine defaultHost=localhost name=Tomcat-Apache Engine debug=0 Host name=localhost debug=9 appBase=webapps autoDeploy=true unpackWARs=true Realm className=org.apache.catalina.realm.MemoryRealm / Context path=/testapp docBase=testapp reloadable=true privileged=true debug=1 / /Host /Engine It will unpack correctly if no context is specified, and it will work as shown above if the docBase directory is already unpacked. This will also work if I set unpackWARs to false, and the docBase to the war file, but I really need the war to be expanded in this case. Is there a work-around for this behavior, other than manually unpacking?

Migration from 3.3a to 4.0.4
I am new to Tomcat 4, and I am trying to move an existing webapp from 3.3a to 4.0.4. I am using Apache as the web server, but I am not quite clear on which portions of Tomcat relate specifically to the stand-alone web server configuration versus general webapp serving through a connector (Warp or AJP). For example, the Host container is used to define virtual hosts, but is this necessary if Apache is handling the virtual hosting? Any general comparison or migration steps of Tomcat 3.3 to Tomcat 4 would be helpful. Currently I have multiple Apache virtual hosts served by multiple Tomcat instances (with multiple server.xml, etc.) and everything works fine (in 3.3a). Thanks, Shawn
Announcement: JSP Standard Tag Library (JSTL)
Tomcat users, You might have heard about the JSP Standard Tag Library (JSTL), which is a new standard under the Java Community Process. JSTL 1.0 was finalized at the end of May 2002, and its reference implementation was released as part of Sun's Web Services Developer Pack (WDSP) earlier this month. The goal of JSTL 1.0 is to simplify the development of JSP pages by standardizing tags for the following tasks: - control flow (iteration, conditional logic, and error handling) - URL management (session encoding, cross-context imports, etc.) - text formatting and internationalization (i18n) - XML manipulation (with XPath) - database access (via JDBC) JSTL also offers an expression language for accessing scoped attributes, request parameters, and other data. (This expression language is planned to be the basis of a core addition to JSP 2.0.) Using JSTL tags and the new expression language, you can often avoid scripting elements (scriptlets and scripting expressions) in your pages. JSTL works with a number of different models for web development. Users of a model 2 approach will probably appreciate JSTL's expression language and core tags for control flow; prototypers and developers of small applications may appreciate its SQL tags. Personally, I find JSTL's XML tags to offer a convenient, powerful alternative to XSLT for many common XML-manipulation tasks. And JSTL also offers an API for programmers who wish to configure JSTL and expose data for their JSP pages. I'm sending this message to announce that Jakarta Taglibs has just released version 1.0 of its Standard Taglib, an implementation of JSTL. (The implementation at Jakarta Taglibs is also the basis for Sun's reference implementation of JSTL.) You can download the 1.0 release of the Standard Taglib at http://jakarta.apache.org/builds/jakarta-taglibs/releases/standard/ The Standard Taglib requires JSP 1.2; it has been tested with Tomcat 4.0.4. (Earlier versions of Tomcat may have trouble loading the JAXP 1.2 classes included with our distribution, so I recommend using Tomcat 4.0.4. A set of older XML files is available from the URL above if you want to use an older version of Tomcat.) I'm happy to answer questions that you have about JSTL; for detailed discussion, you might be interested in joining the 'taglibs-user' mailing list at Jakarta; see http://jakarta.apache.org/site/mail.html for instructions on how to do so. For general information about JSTL, as well as a link to the formal specification, pointers to upcoming books on JSTL, and current articles, see http://java.sun.com/products/jsp/jstl/ If you have any comments for future versions of JSTL, you can submit them to our expert group by mailing [EMAIL PROTECTED] Enjoy, -- Shawn Bayern JSTL reference implementation lead Author, JSTL in Action http://www.manning.com/bayern (July 2002) -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Help Preventing VM Tomcat Crash
Looks like you are using the JDBC-ODBC bridge (maybe to an MS Access or MS
SQL Server database?), which is not thread-safe and is not intended for use
in production environments. My guess is that one thread (the current thread
servicing the Thumbnail servlet) has a db connection open, and the next
request (the user clicking the thumbnail) opens another db connection. This
guess is based on these lines in your exception:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : unknown exception code occurred at PC=0x77fb16cc
Function name=RtlTraceDatabaseEnumerate
Library=C:\WINNT\System32\ntdll.dll
If this is the case, try finding a pure Java (type 4) JDBC driver for your
database.

RE: Help Preventing VM Tomcat Crash
So much for that theory.
However, your guess is pretty close. I found something which you might find
interesting. This is a known bug, which you can check out here:
http://developer.java.sun.com/developer/bugParade/bugs/4502892.html
The problem occurs when the socket is prematurely closed. The workaround is
to buffer the output via ByteArrayOutputStream, isolating the native method
from stream disconnections.
The evaluation of the bug I will include here for convenience:
***
The JPEG library is not MT-safe. In particular, there is a definition of
a global variable struct error_mgr ek_err which is used by all threads
for error handling -- including a setjmp buffer. Consequently, when an
error does occur while more than one thread is executing in the native
library, it is common for that thread to longjmp to another thread's state.
It then uses the wrong JNIEnv pointer and trashes the VM.
x@x 2001-10-09
This bug has indeed been fixed in merlin-rc1, but its associated regression
test
(JPEGMultithread.java) is confusing and potentially misleading. This is
addressed by another bug (4546112 - Reg-test JPEGMultithread.java Failing).
The regression test currently throws exceptions endlessly if bug 4502892 is
not
present, and hangs or crashes the VM if bug 4502892 is present. This is bad
behavior for a regression test, so it will be updated in accordance with
4546112.

Hope this helps more,
Shawn

Hi Shawn,
Many thanks for the note the suggestion! I am using MySQL as my Db and
MM.MySQL is my driver (mm.mysql-2.0.11-bin.jar). Given that this is a Type
4 driver, I don't think I should be getting a native code crash involving
database access, right?
I could be missing something, but it seems that the
sun.awt.image.codec.JPEGImageEncoderImpl.writeJPEGStream() method (which is
native code) is trying to write to my output stream and running into
trouble. I assume this is because the user has clicked on an image serving
as a link to another web page and now Tomcat is off trying to handle the
new page. My best guess is that in the process of doing so, the output
streams used by writeJPEGStream() are being torn down, but the native code
doesn't know this and it's causing the VM to puke. Does anyone think my
logic makes sense? Better yet, does anyone know a way to prevent it? :-)

Working: mod_webapp -- NT4, Tomcat 4.0.7, Apache 1.3.20, JDK 1.3.1
Sorry if it seems as if I reposted it, I was having trouble with the office machine, so I sent it out under a new subject, since it was different than the one I posted before... when I ran Apache from the command line with the webapp modified conf here is what I get. D:\webserver\ApacheApache Syntax error on line 176 of d:/webserver/apache/conf/httpd.conf: Cannot add module via name 'mod_webapp.c': not in list of loaded modules took that line out and it works... I can see webapp-info and IT WORKS ... INSTALL.txt [..] *- Another note for Windows: copy also the libapr.dll file with the module, or your Apache 1.3 web server will refuse to start reporting that the WebApp module cannot be loaded. Once you have done that, edit your httpd.conf configuration file and add a few lines to load that module at startup (Windows users, read above, you have to replace libexec with modules - I'm paranoid, sorry): LoadModule webapp_module libexec/mod_webapp.so and AddModule mod_webapp.c [ DO NOT ADD THIS TO WINDOWS ] -* Thanks for the help Shawn - Original Message - From: Pier P.
