Since I have eclipse ee europa installed, I realized I needed to upgrade
my java from se 1.5 to the java ee 5 SDK, so I downloaded to
SDK with JDK .bin file from the sun site, and have made all the necessary
changes that I know of, but if I say 'which javac', it says /usr/bin/javac.
This is a real bugger of a problem, here's what I've done to try to
fix it:
I have java version "1.5.0_11", I cant compile servlets so I installed
this one, the SDK with JDK : java_ee_sdk-5_03-linux.bin, in /opt/SDK/jdk
Problem is, if I do javac, it only finds the 1.5 version, so I cant
compile servlets. I've reset $JAVA_HOME to /opt/SDK/jdk, doesnt help.
My other java and javac are in /opt/SDK/jdk/bin. Since I installed the
first
Java, the 1.5 one, using apt-get everything worked, so I thought maybe if I
tried to make a deb package out of the new Java, it might work.
So I did apt-get install java-package.
Here's what I did after that:
cuco@coat:~/Desktop$ fakeroot make-jpkg java_ee_sdk-5_03-linux.bin
Creating temporary directory: /tmp/make-jpkg.WOrlLt6874
Loading plugins: blackdown-j2re.sh blackdown-j2sdk.sh common.sh
ibm-j2re.sh ibm-j2sdk.sh j2re.sh j2sdk-doc.sh j2sdk.sh j2se.sh sun-j2re.sh
sun-j2sdk-doc.sh sun-j2sdk.sh
Detected Debian build architecture: i386
Detected Debian GNU type: i486-linux-gnu
No matching plugin was found.
Removing temporary directory: done
I'm about ready to give up at this point, any ideas on what to try ?
update-alterenatives doesnt find the right java either.
I dont know how to deal with the plugin issue. I posted a thread on the
ubuntu
forums and looked at similar threads there, but no answers.
I thought I'd try here, even though is only indirectly related to eclipse

Hi Adam. This is probably a dumb question, but... As you may know,
Eclipse doesn't care about the $JAVA_HOME and javac stuff (unless of
course that means that the correct JRE is not properly installed).
So, have you actually tried going into Eclipse and checking if the JRE
is visible there? (Window/Preferences/Java/Installed JRE's) A long shot,
to be sure, but worth checking. HTH. Mark

It was a bit hard for me to tell, but I think Adam's question was unrelated
to Eclipse... sounds to me like he's having trouble using javac at the
command line.
If the issue is happening within Eclipse, the right answer is probably to
specify the JRE explicitly on the Eclipse command line or .ini file; and to
add the JRE within Windows -> Preferences.

It's not clear what your problem actually is. Java EE is api on top of
Java SE. There isn't a separate compiler for Java EE. Could you be
more specific on what you are trying to do, what you are expecting, and
what you are actually seeing.

I will try to be more specific about my problems.
I am trying to set up eclipse > tomcat > mysql development on my ubuntu
laptop
to java enterprise web development. I am a noob at doing this kind of
stuff, so
please forgive me if I say or do some dumb things.
When I try to start tomcat from eclipse, I get some error msg like
'Failed to publish ... configuration may be corrupt'.
It lists the directory in eclipse as Servers/apache-tomcat-6.0.14, on my
machine its actually in /usr/local/tomcat/apache-tomcat-6.0.14., not sure
if that matters. Whether I have previously started tomcat from a terminal
window or not,
it doesnt seem to matter as far as getting it to work in eclipse.
I did add apache-tomcat to my Servers (in eclipse), it shows up as
apache-tomcat-6.0.14.
As far as my Java issues go, I just now tried the suggestion of going to
Windows > Preferences in eclipse to see if I could find the new JRE I
installed
from there. I tried to add it by navigating (in that window that comes up)
to /opt/SDK/JDK/jre and hit add. It says there's jre found there !
I was initially confused about what to install from Sun's Java download
site.
As I said, I had a while back installed the sun-java-1.5 package using
apt-get.
When I looked at the Java 1.5 API docs, I didnt see any class definition
for
HttpServlet, so I figured I needed the Java ee 5 SDK edition. I first
downloaded the .bin that didnt include the JDK (since I already had a JDK),
nothing worked, so I removed my SDK directory and all the files in it, and
then downloaded the .bin with the JDK to /opt/SDK. So now I have
java ee 5 SDK (with JDK included) installed in /opt/SDK. There's a jre
directory in there, so I'm assuming everything I need Java wise should be
in /opt/SDK.
I have reset my $JAVA_HOME in my .bashrc (and in my /etc/bash.bashrc, this
is
ubuntu,so I did it there too, dont know if I needed to) to
/opt/SDK/jdk. (I'm wondering if I should have set it to /opt/SDK/jdk/bin or
something. )
I have a very simple HelloServlet.java located in
/usr/local/tomcat/apache-tomcat-6.0.14/webapps/ROOT/WEB-INF
When I do javac HelloServlet.java, I get the error message
'package javax.servlet.http does not exist'.
If I do a 'which java' or 'which javac' I get /usr/bin/java or
/usr/bin/javac.
I have a javac and a java for the new version I just installed in the
bin directory off /opt/SDK/jdk, so the new javac and java for the
java ee 5 SDK with the jdk are there, itlooks like there's a whole jre off
that /opt/SDK/jdk, but for some reason, only the jre that I originally
installed
in /usr/lib/jvm gets found. I havent found a jvm directory off of
/opt/SDK/jdk,
but I think all the same stuff is probably in there, just in different
directories.
By the way, if I go to localhost:8080, I get the tomcat home page, so its
set up correctly. When I start tomcat, I get this :
root@coati:/usr/local/tomcat/apache-tomcat-6.0.14/bin# ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.14
Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.14
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.14/temp
Using JRE_HOME: /opt/SDK/jdk
Not sure what to make of this problem. Any ideas on what to do about this
would be awesome, I'm about at my wits end. Sorry for the long post.

Here's what happens when I try to run update-alternatives for java and
javac:
root@coati:~# update-alternatives --config java
There are 2 alternatives which provide `java'.
Selection Alternative
-----------------------------------------------
1 /usr/bin/gij-wrapper-4.1
*+ 2 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
Press enter to keep the default[*], or type selection number:
root@coati:~# update-alternatives --config javac
There is only 1 program which provides javac
(/usr/lib/jvm/java-1.5.0-sun/bin/javac). Nothing to configure.
root@coati:~#
As you can see, only the one comes up.
As a hack, I briefly thought about trying to edit this file:
root@coati:~# cat /var/lib/dpkg/alternatives/javac
auto
/usr/bin/javac
javac.1.gz
/usr/share/man/man1/javac.1.gz
/usr/lib/jvm/java-1.5.0-sun/bin/javac
53
/usr/lib/jvm/java-1.5.0-sun/man/man1/javac.1.gz
but without knowing what I'm doing, I thought it would be foolish to try
something like that. (I think this is one of the places
update-alternatives looks)
The other hack I thought of was making a symlink from the one to points to
now
to the one I wanted. The problem with that idea is that the directory
structure is a bit different in the version I have in /opt/SDK/jdk, that
also
seems risky if there are other things that the system depend on to find
the right files that aren't changed also. Thats why creating the deb
package seemed the way to go, then I could have ubuntu do the configuring
for me.

java-1.5.0-sun is itself a symlink to java-1.5.0-sun-1.5.0.11, the actual
location. That'a why I was thinking of changing the java-1.5.0-sun symlink
to point to somewhere like /opt/SDK/jdk. I'm not sure if you can change
the value
of a symlink to a new value, maybe that would be a solution if I knew
everyplace
I needed to do it.
What file would I edit to change the config for eclipse ?
(Right now I cant even run tomcat from eclipse, but changing eclipse to
use the Java I want would be a start) Thanks for the help, by the way.
I'm amazed at how difficult it is to find any good docs on any of this.

I think your getting to hung up on which VM you are running. There is only
one Java 1.5 VM. JSE and JEE refer to the jar files that are included in
each version. JSE is the base version of Java. JEE adds additional jar
files to provide the EE functions. You need to get the EE jar files on a
classpath before you can compile anything against the EE api.
Have you tried to go through some basic servlet tutorials? This might help
you get things figured out. Sun has an extensive EE tutorial at
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html.
One of the chapters has a tutorial for servlets.

The troubles you are having is exactly the reason why system-wide
classpath and JVM settings are to be avoided at almost any cost, IMO.
Each app should be told explicitly what JVM to run under.
Anyway, there are lots of examples of eclipse.ini in the archives of
these newsgroups - Google can find them for you.
Here is a page that talks in detail about the eclipse.ini file,
including the -vm option that you are most interested in.
http://www.eclipse.org/swt/launcher.html
Hope this helps,
Eric

Hi Adam. I think the JRE (Java Runtime Environment) includes the JVM. I
find this very confusing, even after just trying to read the Wikipedia
definitions of both. If I'm reading correctly, the JVM is just the
program that actually runs the .class files for that hardware platform
(e.g., java.exe on Windows), and the JRE includes both this and the
bundled class libraries that come with the Java language (i.e., the
rt.jar and other .jar files included with the JRE).
So there is no separate JVM download that one would normally use. HTH. Mark

Yes, you are right. For ex., the path /opt/SDK/jdk/demo/jvmti has the same
files as /usr/lib/jvm/java-1.5.0-sun-1.5.0.11/demo/jvmti.
I changed the version in eclipse.ini to 1.6 which is the one that is
included in the SDK that I downloaded.
After reading that link posted by Eric, I thought I would try launching
eclipse from the command line, using the -vm option to pass in the right
VM that I wanted. I'm not sure how to refer to the VM, though. I've tried
various things
like root@coati:/opt/eclipse# ./eclipse -vm javaVM1.6. Seg fault there.
I've also tried using the entire path,ie
root@coati:/opt/eclipse# ./eclipse -vm /opt/SDK/jdk/jre/bin/java_vm.
Evidently you cant launch it from the comand line without getting a
segfault,
maybe it has to do with an X11 display var not being set. Here's what it
says:

I have no idea what java_vm is, but I'm pretty sure the java executable
for the Sun JDKs and JREs is just named 'java'
So you'd need to specify -vm /path/to/where/java/is/installed/bin/java
The value of the -vm option must be the full path to the java executable.
I honestly don't understand why you're having so much trouble -
thousands of people run Eclipse on Linux every day. I would recommend
installing the Sun JDK into a new location and then editing eclipse.ini
to point to its java executable. On one Red Hat system I use, that is
/usr/java/jdk1.5.0_07/bin/java
Hope this helps,
Eric

I was thinking maybe it would be better to put it in the /usr dir.
I just tried starting the application server:
/opt/SDK/jdk/bin/asadmin start-domain domain1
Which I was able to start with the other install, but not now. The asadmin
program is not even there. it seems like the documentation that Sun gives
you
might not even be correct for the version you've downloaded.
Is the Sun application server even something I need to worry about ?
I want to delete everything I've downloaded and start from scratch.
Any advice on which version to download ?
http://java.sun.com/javaee/downloads/?intcmp=1282
Sun's site is confusing about what you need. If I could get away with
using J2SE 1.6 I could just use apt-get and everything would be fine.
But I dont see any class definition for HttpServlet in the API docs,
so I'm assuming I need j2ee 5.
One option would be to just keep the j2se 1.5 that I have now and just
download the ee 5 SDK, but I'm not sure where to put the download package
to
make sure files will be found by 1.5 compiler.
Here's what my current directory structure looks like for the 1.5 version
that I installed using apt-get:
root@coati:/usr/lib/jvm/java-1.5.0-sun-1.5.0.11# ls
bin docs jre man src.zip
COPYRIGHT ext lib README.html THIRDPARTYLICENSEREADME.txt
demo include LICENSE sample
Downloading the .bin file from the Sun site and running it extracts
everything
into a directory called SDK. Any idea where I should put that directory ?
What's weird is all the stuff having to do with jdk is in
/usr/share/doc/sun-java5-jdk, they're all documentation files. (This is
for the
1.5 version, I did an apt-get for the docs)
Anyway, what I recently downloaded and installed in /opt was from this
download: java_ee_sdk-5_03-linux.bin (update 3) This seems like it should
should be the right one.
Maybe the easiest question to ask would be, for those of you that manually
downloaded and installed some version of java ee on Linux, (with the tomcat
container), how did you get it working so you could compile and run simple
servlets on it ? I think if I get that working it will be easier to focus
on the eclipse configuration knowing that at least the Java part works.
