Re: Configuring Tomcat 5.5 and IIS 6
Glenn, Thanks for this - it looks like a very comprehensive guide. I'll have another go at setting it up later on today and report back.

Hi All
Anyone knows how to deal with null values in JDBC ResultSet??
I am trying to render a table in jsp page that read its value from the
database, sometimes, the database returns null values, and so, the whole
table couldn't be rendered. Is there any way to deal with null values.
The correct way to detect nulls in a JDBC ResultSet is rather different
from
the replies you've had so far. You should detect the presence of nulls in
a
given result set row by using the ResultSet.isNull() method.
So, let's say that we have a result set called 'rs' (you will probably
have
used a Statement or PreparedStatement or some other technique to get your
result set from the database):
Statement stmt = ; //an arbitrary Statement object
ResultSet rs = stmt.executeQuery(select employee_number, last_name,
first_name, middle_initial from employee_table);
Now, on to the matter of nulls. Let's say that you are working your way
through your ResultSet. As you know, you get the rows of the ResultSet one
row at a time, using the next() method, as follows:
while (rs.next()) { //as long as there are rows in the result set
//handle one row of the result set
}
Within the while loop, each iteration of the loop will handle one complete
row of the result set.
Let's assume you don't know which columns of the result set are null and
you
want to display the values in each column of the result set exactly as
they
appear in the result set, except that when the value is null, you want to
display the word unknown. Here's what you would need to do:
String empno = null;
String lastname = null;
String firstname = null;
String midinit = null;
while (rs.next()) {
empno = rs.getString(employee_number); //get the employee number
from this row of the result set
if (rs.wasNull()) { //if the employee number is null
System.out.println(Employee Number is unknown);
}
else {
System.out.println(Employee Number is + empno);
}
lastname = rs.getString(last_name); //get the last name from this
row of the result set
if (rs.wasNull()) { //if the last name is null
System.out.println(Last Name is unknown);
}
else {
System.out.println(Last Name is + lastname);
}
firstname = rs.getString(first_name); //get the first name from
this row of the result set
if (rs.wasNull()) { //if the first name is null
System.out.println(First Name is unknown);
}
else {
System.out.println(First Name is + firstname);
}
midinit = rs.getString(middle_initial); //get the middle initial
from this row of the result set
if (rs.wasNull()) { //if the middle initial is null
System.out.println(Middle Initial is unknown);
}
else {
System.out.println(Middle Initial is + midinit);
}
}
Although this example uses only result set columns that are being stored
in
Strings, the technique differs very little for non-text data. Let's say
that
we had a column called annual_salary in our result set, where the
annual_salary was an integer containing the number of dollars that the
person earned per year. Let's assume that some people are still
negotiating
their salaries so that the salary is stored as null for those people until
the salary has been fully agreed.. The technique to handle the salary
would
look like this:
int salary = null;
while (rs.next()) {
salary = getInt(annual_salary); //get the salary from this row of
the result set
if (rs.isNull()) { //if the salary is null
System.out.println(Annual Salary is unknown);
}
else {
System.out.println(Annual Salary is + salary);
}
I hope this helps you with your null handling!

Re: Fw: [nbusers] GlassFish VERSES Tomcat
glassfishes uses a fork of tomcat 5.0.25, which they are developing on their own. Its actually the same as JBoss, the tomcat which comes with JBoss isn't the tomcat you get from tomcat.apache.org. The same applies probably to any application server out there, they all come with their servlet containers, own products or a customized version of another product. But as long as they are all compatible to the JSR (or at least mainly compatible) it shouldn't be a problem or a big problem to migrate from one to another. As long as you don't use tomcat specific things, like valves, in which case you're damned, but its your own fault then. regards Leon On 6/24/07, Johnny Kewl [EMAIL PROTECTED] wrote: - Original Message - From: Johnny Kewl To: [EMAIL PROTECTED] Sent: Sunday, June 24, 2007 1:41 PM Subject: [nbusers] GlassFish VERSES Tomcat Guys, this is bothering me...

Re: Null
If you check the Java API, wasNull() _is_ a method of the interface
ResultSet. (Sorry, I mistakenly referred to it as isNull() before I started
giving you the example.) If your program contains:
import java.sql.ResultSet;
you should be able to see the wasNull() method without any difficulties.
The example I gave was adapted from a program that I created a while back as
a JDBC example for use in database courses. I've run the program
successfully many times. If your rs.next() compiles, I see no reason why
rs.wasNull() would fail to compile.

Re: URI handling bug in Tomcat 6.0.13?
Thanks, so if I got it right - due to some security reasons: Directory traversal vulnerability in Apache HTTP Server and Tomcat 5.x before 5.5.22 and 6.x before 6.0.10, when using certain proxy modules (mod_proxy, mod_rewrite, mod_jk), allows remote attackers to read arbitrary files via a .. (dot dot) sequence with combinations of (1) / (slash), (2) \ (backslash), and (3) URL-encoded backslash (% 5C) characters in the URL, which are valid separators in Tomcat but not in Apache. ... I cannot use sequence of .. (dot dot), /, \ and %5C Yes, but, it is strange since I do have neither (dot dot) nor %5C nor \ [we cannot ban / completely, right?], Tomcat seems to be reacting strange on %2F, which have to be URLEncoded, since this is a URI I am passing to an internal procedure, if this URI is not URL encoded - than my regexp defined REST services endpoints will freak out and consider only all they will see till / as a parameter. As I said before - it seems that Tomcat is sensitive to a %2F in my URI, which is not on the list above. http://localhost:8080/jeromedl/mbb/filter/marcont:hasDomain/http%3A%2F %2Fdmoz.org%2FTop Can you, please, explain what is wrong with this URI?

RE: Is ThreadLocal safe to use in servlets
To conserve resources when multiple Connector elements are configured.
No point in having a multitude of idle threads when some Connectors
are only lightly used or the usage pattern varies with time.
Is it safe to assume that this is the way to go, or are there ever, ever any
times when it would be less desirable to go this route than the default
thread-pool-per-connector element? (I ask in terms of performance or other
production characteristics, rather than the initial extra few minutes to
configure that element and figure out how to correctly use it...?)
Also, using this method can threads only be shared between Connectors
associated with a single Engine (because Executor is a child of Service, not
Server), rather than being shared between every request to all web
applications on this instance of Tomcat?
I have another question about using ThreadLocal as an instance variable in a
threadsafe Singleton. If the Singleton has 5 instance methods, each of which
requires use of the value stored in the ThreadLocal, I see one option:
- Start each method with a call to a private method that returns the value
in the ThreadLocal
void method1of5() {
String myString = getStringFromThreadLocal();
myString.doStuff();
}
Is there another alternative, which would reduce the duplication of that
first line for each of the five methods? One thing I thought of (though it's
not possible, but maybe you can suggest other alternatives) is to somehow
have an instance variable that stores the value of that call, that each
method could use directly?
String myString = getStringFromThreadLocal();
void method1of5() {
myString.doStuff();
}
Of course this isn't possible the way I've shown, because the myString
instance variable is only initialized once, and shared between all users of
the Singleton. (Though it does simplify each of the 5 methods, making them
oblivious to the fact that they're dealing with ThreadLocals, and that's
what I'm hoping you might be able to suggest a way of doing...)

RE: Port-based virtual hosting
From: lightbulb432 [mailto:[EMAIL PROTECTED] Subject: Port-based virtual hosting Is there any functional difference between the two options - if they're both even possible? Which would you go with? - 1 Service element with 5 HTTP connectors (each on a different port) and one Engine with 5 Hosts (Host name=application.com:8080, Host name=application.com:8081, etc...) - 5 Service elements, each with 1 HTTP connector and one Engine with only 1 Host Not sure I understand your requirements. Are you trying to implement multiple virtual hosts that are segregated by port number rather than DNS name? Your first option is not likely to work, since the port number is stripped off before comparison with the Host name is done. (Also, since the Host name is used as a directory name in the underlying file system, the colon won't be allowed on many platforms.) The first option would use less resources than the second one, but I think it would require that you write a Valve to forward each request to the proper Host. I think the second one will work without any additional coding (but I haven't tried it). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

In-Process Tomcat
I read a few things that explained the difference (in configurations where you must front Tomcat with Apache HTTPD) between in-process Tomcat and out-of-process Tomcat, and have a couple of questions. It said that in-process Tomcat will reduce latency (which I understand) but decrease both stability and scalability - why will it decrease both of these things? How can you set up an in-process Tomcat? I couldn't find anything related at http://tomcat.apache.org/connectors-doc/ or by doing a web search. Do both options make use of the mod_jk connector to HTTPD, and it's just a matter of configuring it appropriately, or does Tomcat somehow have to be compiled into Apache, or something else? In general, what conflicts arise from an integrated Tomcat and HTTPD setup, whether in-process or not? Both Tomcat and HTTPD have configuration related to URL rewriting, authorization/authentication, logging, etc. In general terms, what's the most reasonable way to configure your integrated setup so that the resulting installation doesn't leave security holes, or break due to URL rewriting, or any other results? An strategies or best practices here? -- View this message in context: http://www.nabble.com/In-Process-Tomcat-tf3972772.html#a11276703 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: In-Process Tomcat
In-process Tomcat is to have Tomcat running in the same process space as Apache HTTPD, IIS, or other web server. Since most of the web servers are implemented in C/C++, you will have to use JNI to integrate with Java-based Tomcat, and create a mod_tomcat like module for Httpd. Definitely the in-process setup improves performance, since communication between Tomcat and web server occurs via memory-based data exchange. It will be less stable since if something went wrong with the Tomcat, it would affect the web server directly. It will also be less scalable, since this setup won't support high-availability and clustering of Tomcat servers. Out-process Tomcat, on the other hand, is running as an independent server in a different process space or on a different machine as the HTTPD server. It may lack the performance as the in-process set up, since the communication between Tomcat and HTTPD occurs via network. But it is definitely more stable and more scalable than in-process Tomcat. I don't think that in-process Tomcat is much used nowadays, since it is hard to configure and very error-prone. The common way of using Tomcat with a front end HTTPD is the out-process one, since it is more flexibly and easy to configure. The common architecture is to have the front-end HTTPD running in a DMZ, serving static pages, while one or more Tomcat servers hosting the dynamic application running behind the firewall. In this case, the out-process Tomcat is the only option. Hope this helps. ND -Original Message- From: lightbulb432 [mailto:[EMAIL PROTECTED] Sent: Sunday, June 24, 2007 1:33 PM To: users@tomcat.apache.org Subject: In-Process Tomcat I read a few things that explained the difference (in configurations where you must front Tomcat with Apache HTTPD) between in-process Tomcat and out-of-process Tomcat, and have a couple of questions. It said that in-process Tomcat will reduce latency (which I understand) but decrease both stability and scalability - why will it decrease both of these things? How can you set up an in-process Tomcat? I couldn't find anything related at http://tomcat.apache.org/connectors-doc/ or by doing a web search. Do both options make use of the mod_jk connector to HTTPD, and it's just a matter of configuring it appropriately, or does Tomcat somehow have to be compiled into Apache, or something else? In general, what conflicts arise from an integrated Tomcat and HTTPD setup, whether in-process or not? Both Tomcat and HTTPD have configuration related to URL rewriting, authorization/authentication, logging, etc. In general terms, what's the most reasonable way to configure your integrated setup so that the resulting installation doesn't leave security holes, or break due to URL rewriting, or any other results? An strategies or best practices here? -- View this message in context: http://www.nabble.com/In-Process-Tomcat-tf3972772.html#a11276703 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Java Axis and R
Hi all, I've been asked to develop a Java Axis web service to call R program (http://www.r-project.org/). There is a Java/R interface (http://www.rforge.net/rJava/) has been developed and allows to call methods and access R object from Java. So my application is running fine as a normal Java application. However, it fails to run the R program when it is running as web service. Well from my experience, I guess the only reason to cause it was because Tomcat doesn't allow its own web applications to consume other programs that are not inside Tomcat. Similar situation happen before when I was trying to use System.getenv(CATALINA_HOME). It was running fine as a normal Java application, but doesn't work when it is running inside Tomcat. So does anyone know how to configure Tomcat to use other programs that are not inside Tomcat? By the way, the version of my tomcat is 5.5.23. Thanks in advance Kind Regards Eric Jiang
Re: Java Axis and R
Hi there, Check out CGIwithR package. http://www.omegahat.org/CGIwithR/ I have been using it for a while. You can execute R scripts and post the output to using RHTML package or using simple print. hope it helps, Kaustubh On 6/24/07, Yifan (Eric) Jiang [EMAIL PROTECTED] wrote: Hi all, I've been asked to develop a Java Axis web service to call R program (http://www.r-project.org/).

Deploying single .war file for use by multiple contexts - how do i override web.xml
Hi all,The problem is we have 4 different sub companies which we want to deploy a particular web app for.What we want to do is stick a single .war file onto the server which all companies point to,and set up different context.xml files for each (since they have different context data).The problem is we also want different data (particularly the security role data) in the different web.xml files but these are stuck in the .war file.So the question is:Can we use the context file to alter the security role data (or more accurately override it) in the web.xml file depending on which company is using the web app.Thanx in advance RegardsSteven Probetts Ph 9309 0555 Fax 9409 6828 Mb 040 968 487724 Mosey Street LANDSDALE WA 6065This email message is for the intended recipient(s) only and may contain confidential or privileged information.

RE: Deploying single .war file for use by multiple contexts - how do i override web.xml
From: Steven Probetts [mailto:[EMAIL PROTECTED] Subject: Deploying single .war file for use by multiple contexts - how do i override web.xml Can we use the context file to alter the security role data (or more accurately override it) in the web.xml http://web.xml/ file depending on which company is using the web app. Perhaps. You can't override the web.xml settings, since that information is defined by the servlet spec, and things in Context are outside of the spec. However, you could specify a different Realm inside each Context, and that might suffice. You could also use a Filter to implement the necessary security, possibly in conjunction with the web.xml settings. I seem to recall that there are some open-source security Filters already available that have been mentioned in other threads. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Run multiple instances of tomcat on windows

Re: Run multiple instances of tomcat on windows
I think that you are installing tomcat with the windows installer thats is not a good idea. I ever install tomcat with the file ziped; there, in the bin directory you find a service.bat, with this bat you can install tomcat as a windows service... and... you must install the services that you want. May be you wana modify the service.bat and add the TOMCAT_BASE environment variable.

RE: In-Process Tomcat
Thanks for your detailed response. See questions below. In-process Tomcat is to have Tomcat running in the same process space as Apache HTTPD, IIS, or other web server. Since most of the web servers are implemented in C/C++, you will have to use JNI to integrate with Java-based Tomcat, and create a mod_tomcat like module for Httpd. So there's no standard prepackaged installation of the two combined, or no standard connector plugin or something that's distributed with either Tomcat or HTTPD, which is why I'd have to create it myself? Is the in-process approach that uncommon? Definitely the in-process setup improves performance, since communication between Tomcat and web server occurs via memory-based data exchange. It will be less stable since if something went wrong with the Tomcat, it would affect the web server directly. It will also be less scalable, since this setup won't support high-availability and clustering of Tomcat servers. Why does the in-process approach render high-availability and clustering impossible? From a technical/implementation perspective, what is it about the in-process approach that causes this specific functionality to not be possible? In any case, if clustering features don't work then it's definitely no surprise that any web application that needs to scale wouldn't use this approach...unless it is being used in some way by such web applications in production - anybody know? -- View this message in context: http://www.nabble.com/In-Process-Tomcat-tf3972772.html#a11281236 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Port-based virtual hosting
The question's more of a general one to help me understand some elements in server.xml. Maybe I'll start with this question first, though: If you somehow have multiple contexts (within the same Host or Service, or within different ones in your Tomcat instance) that point to the same WAR file or docBase, are there multiple instances of that web application running, or are the multiple entry points to that application (based on it being specified in multiple hosts) really pointing to the same instance of that webapp? If this doesn't make sense, I can clarify. Thanks. Caldarale, Charles R wrote: From: lightbulb432 [mailto:[EMAIL PROTECTED] Subject: Port-based virtual hosting Is there any functional difference between the two options - if they're both even possible? Which would you go with? - 1 Service element with 5 HTTP connectors (each on a different port) and one Engine with 5 Hosts (Host name=application.com:8080, Host name=application.com:8081, etc...) - 5 Service elements, each with 1 HTTP connector and one Engine with only 1 Host Not sure I understand your requirements. Are you trying to implement multiple virtual hosts that are segregated by port number rather than DNS name? Your first option is not likely to work, since the port number is stripped off before comparison with the Host name is done. (Also, since the Host name is used as a directory name in the underlying file system, the colon won't be allowed on many platforms.) The first option would use less resources than the second one, but I think it would require that you write a Valve to forward each request to the proper Host. I think the second one will work without any additional coding (but I haven't tried it). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
