Installing and runing JBoss without JDK

[arun_9033]

Hi All,

I am newbie here. Just would like to clear my head on this:-

Is it possible to install and run JBoss4.03 without JDK (valid version)?

I understand that JBoss4.0.3 has an embedded tomcat that uses JDK for compliing JSP and servlets.

JBoss won't start if don't have JAVA_HOME pointing a JDK on the machine.

Any pointer to previous discussion or link appreciated.

Hi.

JBoss needs a JDK to run. The startups script is infact a jar.

Thanks for the confirmation - this just came up after I read the Book JBOSS Developer Note Book where the author mentions

" As of version 4.0.2, Tomcat ships with its own complier, so JBoss only requires a JRE Install."

Does that mean JBoss shall use inbuilt Tomcat and it's jDK?

I guess someone will arrest me if I'm spreading wrong information here.. :P

I don't really know if you need a JDK on second look. I guess you just need a java VM.. so a JRE should be sufficient.

after some googling I found this product sheet.. It clearly states that one of the minimum requirements is a JDK

You do not need a JDK, only a JRE. It tried it, its works. My setup was Windows XP, JRE 1.4.2_11 and JBoss 4.0.4GA. I set JAVA_HOME to my JRE, cleaned out the temp and work directories under server/default, launched the server, and accessed my JSPs just fine.

Took me all of 2 minutes to verify that this was possible.

Thanks

This does work when using JBoss 4.0.4, how about the previous version of 4.0.2 where the tmp and work directories don't exist?

[arun_9033]

Actually I am mistaken, JAVA_HOME was pointing to the JDK directroy when it worked. When I change JAVA_HOME to point to the JRE directory, it doesn't work.

The run.bat file thats starts up JBoss requires the tools.jar file which is currently found in the JDK directory...

Can you please send me the batch file that your using... or the directory you have set JAVA_HOME to point to.

Thanks

Um, the tmp and work directories exist in 4.0.2 (and 4.0.3 and 3.2.6 and 3.2.7 and ...).

Here is how I set JAVA_HOME:

set JAVA_HOME=C:\Program Files\Java\j2re1.4.2_11

This is the default location where the JRE is installed.

The batch file is used is the run.bat that came with JBoss, no modifications. Here is the console output (abbreviated) for JBoss 4.0.2:

[d:\apps\jboss-4.0.2\bin]
>run -c servlets
Could not locate C:\Program Files\Java\j2re1.4.2_11\lib\tools.jar. Unexpected re
sults may occur.
Make sure that JAVA_HOME points to a JDK and not a JRE.

Opened a browser and accessed my application just fine. I did start with a fresh installation of JBoss with no tmp or work directories for the 'servlets' configuration, so the JSPs had to be compiled.

Jboss4.4 & Tomcat5.5 compiles jsp using Eclipse JDT compiler as the default. So you don't need Sun jdk unless you choose to use javac to compile your jsp by uncommenting:

<init-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.5</param-value>
</init-param>
