RE: Problem with Tomcat on iSeries -- JAVA400-L

What you have done is just about right.

I hadn't read these two articles. They are both very good. Don Denoncourt's is dated 2005 when I was first installing Tomcat 5.028, though he says to install Tomcat 5.5 with Java 1.4. Personeni's article isn't dated, but he is also talking about 5.028 and Java 1.4.

Denoncourt errs a little. Tomcat 5.5 will run with Java 1.4 but is designed for Java 1.5 (Java 5.0 is another name for Java 1.5). Some of the JSP functions will fail using Tomcat 5.5 with Java 1.4. I found this out the hard way.

Tomcat 5.028 is the last release of Tomcat designed to run with any Java earlier than Java 1.5.

The version of Tomcat you are trying to install, Tomcat 6.037, is a very current release. It will start up under Java 1.4 but isn't going to work fully. At Java 1.5 many of the servlet container functions moved to the JVM. So if you try to run a container (Tomcat is a container) built for Java 5.0 with Java 1.4, many of the packages are duplicated in the classpath and some of those packages changed dramatically between the versions. It doesn't all "play nice".

I believe all you need to do is change the value of JAVA_HOME export in your script to /QOpenSys/QIBM/ProdData/Java#VM/jdk50/32bit and remove the -Djava.version setting from your java command line.

Ignore any messages about TTY function. That's a spurious message from QSH and I seem to remember is was fixed with a PTF on V5R4.

Make these changes, try it, and look at the QPRINT file that contains the stdout messages. If it still doesn't work, post those messages here and I'll help more.

I see JHHL has posted that Tomcat may not work under V5R4. That is incorrect. I ran it very successfully at V5R4 for several of my RJS customers.

Hi
Many thanks for your reply, be patient but this are my first steps on
application server so many concepts are unknowed . I tried to install Tomcat
on iSeries following two links :
http://iprodeveloper.com/rpg-programming/day-life-ifs-java-programmer
http://www.compomentis.com/papers/iSeriesTomcat.html
so i olny read this documents and tried to do what I have understand, then as
tomcat don't work I search in google and I have done many tests that don't
give me any result.

So, if possible, I would like to know how to modify the catalina.sh file : what I
have to add and or modify.
Thanks in advance for your help

Pick one JVM, you can't use all three (four) in one invocation. For Tomcat
6.0.37 that has to be Java 5.0 at a minimum. This gives you the choice of
option 7 or 8. The 32 bit version (j9) runs better on V5R4 in most cases. On
v5r4 there are many ways to set the version; and the version stated in the
java command line itself takes precedence over anything set in JAVA_HOME
or java.properties files. In your command line, you specify Java 6 (-
Djava.version=1.6). You don't have Java 6 on your machine. The QSH java
command works its way down through the selection precedence until it finds
a JVM, the one it finds is the last one you specified in JAVA_HOME. The 32 bit
version of Java 5.0 should be fine for Tomcat.

Most of the startup logging for Java and Tomcat goes to stdout. Stdout is an
abstract file that is directed by the OS to an actual file. File in this case is in the
unix sense, not the IBMi sense. QSH sets up stdout to go to a spool file
(QPRINT) attached to the QSH job. (The job created when you first call QSH
from the QCMD command line.) QSH handles translation from ASCII output
to stdout into EBCDIC spool file content. Just display the QPRINT spool file to
see your primary log.

As Tomcat starts to fire up, it creates catalina.out and begins to log there. This
is another ascii stream file. Open it with Windows Notepad so you can read
the ascii. EDTF should translate it for display if the code page is set properly. (I
believe it is F15 that allows you to change the code page.)

I've never used the startup.sh script to start Tomcat; I've always called
catalina.sh directly with the "start" option.

Subject: Problem with Tomcat on iSeries

Hi

i'm trying to install TOMCAT on iSeries but i have problems;

my scenario is :

* iSeries with V5R4 and

* 5722JV1 *BASE IBM Developer Kit per Java
5722JV1 5 Java Developer Kit 1.3
5722JV1 6 Java Developer Kit 1.4
5722JV1 7 Java Developer Kit 5.0
5722JV1 8 J2SE 5.0 32 bit

* Tomcat : apache-tomcat-6.0.37

i have installed Tomcat in a folder called TOMCAT and unzipped the
file apache-tomcat-6.0.37.zip in it; then i have modified catalina.sh
adding this
lines:

export -s JAVA_HOME=/QIBM/ProdData/Java400/jdk14
export -s JAVA_HOME=/QOpenSys/QIBM/ProdData/Java#VM/jdk50/32bit
export -s JAVA_OPTS="-Dos400.awt.native=true -Djava.awt.headless=true
-
Djava.version=1.6 -Xms256m -Xmx512m"

and changed the row "os400=true"

now if i run from QSH the startup.sh i receive this:

startup.sh
/tomcat/bin/catalina.sh: 001-0019 Error found searching for command
tty. No such path or directory.
Using CATALINA_BASE: /tomcat
Using CATALINA_HOME: /tomcat
Using CATALINA_TMPDIR: /tomcat/temp
Using JRE_HOME: /QOpenSys/QIBM/ProdData/Java#VM/jdk50/32bit
Using CLASSPATH: /tomcat/bin/bootstrap.jar

where could be the problem ? can some help me or suggest some link

that

could help to solve this ?

thanks in advance

p.s. if i open the catalina.out i see strange charatters like ""-@aØÖ-
…•â¨¢aØÉÂÔa×™-"Ä£aÑ¥±åÔa'"'õðaóò'‰£a'‰•a'¥@•-•@£™-

¥£-

K%a£-"ƒ" is normal !!

this is the content of catalinaxxx.log

29-Gen-2014 11.32.52 org.apache.coyote.http11.Http11Protocol pause
INFORMAZIONI: Pausing Coyote HTTP/1.1 on http-8080
