FC5 and Sun's Java

[mastahnke]

In an attempt to get some tomcat applications working, I installed sun's jvm. I used the tar.gz as the documentation indicates from Fedora that using the RPM could break during yum updates due to the "provides" methods of the Sun's RPM.

Step 1. install Sun's JRE
Step 2. Place it in /opt/jre1.5
Step 3. Mess with the hell that is attempting to start tomcat5, configure tomcat5, figure out how to use the alternatives command, use it, google a bunch and still get errors.

Here's the startup error.
[

root@xxx ~]# service tomcat5 start
Starting tomcat5: /usr/bin/rebuild-jar-repository: error: Could not find jdbc-stdext Java extension for this JVM
/usr/bin/rebuild-jar-repository: error: Could not find jndi Java extension for this JVM

                                                           [  OK  ]

Lots of googling and forum reading led me to believe I was close. Certainly, I could rip everything out and use jpackage.org's documentation and packaging methods, but I actually wanted a Fedora system, just with Sun's Java. I wouldn't think that is too hard.

I am kind of a Java administration noob, so please be gentle!

Here is my alternatives list.

I can't find a jre_exports in /opt/jre1.5.


I hope it's something obvious.

Mike, I know NOTHING about Java programming, but Stan Finley's instructions here: http://stanton-finley.net/fedora_cor...otes.html#Java have Sun Java working for Firefox and other programs on my system. Might want to compare notes.

You'll have to initialize the slave references. In a console, type (with root rights):

# JRE=/opt/jdk1.5
# /usr/sbin/alternatives  \
        --install /usr/bin/java                   java          $JRE/bin/java          15004 \
        --slave /usr/bin/rmiregistry              rmiregistry   $JRE/bin/rmiregistry         \
        --slave /usr/share/man/man1/java.1        java.1        $JRE/man/man1/java.1         \
        --slave /usr/share/man/man1/rmiregistry.1 rmiregistry.1 $JRE/man/man1/rmiregistry.1  \
        --slave /usr/lib/jvm/jre                  jre           $JRE/jre                     \
        --slave /usr/lib/jvm-exports/jre          jre_exports   $JRE/jre/lib

This document is written in french but may be a help for you (just read the examples ...).

The base Sun jre package does not include jndi or jdbc, you have to download and install them separately. Also, I'd recommend using the rpm release from Sun.

[mastahnke]

I still haven't got it working. I tried to switch to the SDK, instead of the just the JRE to see if that would help. No luck thus far. I can't believe I am the only one who has had this problem.

Also, is the jdbc stuff a separate package from Sun? I looked for it briefly, but didn't come up with much. Also, the tomcat error logs are not all that helpful to me, but I could attach them.

here's my current alternatives list.

[root@xxx ~]# alternatives --display java

 slave rmiregistry.1: /opt/jre1.5/man/man1/rmiregistry.1
Current `best' version is /usr/lib/jvm/jre-1.4.2-gcj/bin/java.

I also have set the Java option for the second set of alternatives.

Ok, after more fiddleing, I found this: http://fedoraproject.org/wiki/JavaFAQ

This certainly made the JVM part easier. I then deployed my app (I guess anyway, I cp'ed a .war file) to the webapps directory. I can run the jar file from the command line fine, so I think all the java works.

Now I am getting tomcat specific errors (I think). Any suggestions? This is the cataline.out log file. (a snip)

JDBC is provided by the database provider, look for it on the database provider's website.

Here is how I install tomcat: http://www.csfalcon.com/wiki/csfalcon/TomcatServer

did you set the JAVA_HOME environment variable?

[mastahnke]

I think I got it. I guess by default tomcat has no applications deployed. Not even a welcome screen, at least under FC5 defaults. I went to my specific directory and I got data back. I guess that's good.
