Are you running your Tomcat server with a 1.5.0 JRE? See Window >
Preferences > Server > Installed Runtimes > (select Apache Tomcat 5.5) >
Edit > (what's selected in the JRE field?)
If you don't have a 1.5 JRE (yet), it's possible to run Tomcat 5.5 with
a 1.4 JRE, but you'll have to install the JDK1.4 compatibility package
for Tomcat
<
http://tomcat.apache.org/tomcat-5.5-doc/RUNNING.txt>
<
http://tomcat.apache.org/download-55.cgi>
If you run Tomcat with JRE 1.4, you'll probably have to adjust the
version of the Java facet (I've never done it, so I'm not sure). In
Eclipse, edit your projects properties: menu Project > Properties >
Project Facets > (select Java) > Add/Remove Project Facets > (select 5.0
in the row with Java) > (select 1.4 in the dropdown list). [It's not
quite obvious, but the Version column in the project facet wizard is
editable if three dots "..." follow the version number.]
Thanx!!
I have done what u asked, and now the facet problem is gone however
im have a prob with an Enviroment Variable specifically JAVA_HOME
""
root cause
Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK
""
I have been searching the web for the correct path and checking
different forums,
http://forum.java.sun.com/thread.jspa?threadID=556816&start=0
for example, I noticed that there are perhaps to ways to resolve this
1) Create an enviroment var Java_Home,
although I cant find the correct path to my 1.4.2_12
(as in the forum it states to point to the sdk rather than the jre)
2)Copy the tools.jar file into another folder
I found the tools.jar, but unsure what folder to place it into
FYI thank you very much for you quick and speedy reply!!!
Much Appreicated
Reguards CoolT
Where's the error message coming from? When you start Tomcat? When ant
is used? ... Does it appear inside Eclipse on the console?
Probably its the easiest to define the JAVA_HOME environment variable if
you are on Windows. You found tools.jar. Let's say you found it in
C:\Program Files\Java\jdk1.4.2_12\lib
Then JAVA_HOME should be set to
C:\Program Files\Java\jdk1.4.2_12
i.e. the directory above the lib directory where tools.jar resides.
Depending on which Windows you are running follow either 1) or 2)
1) To define JAVA_HOME on Microsoft Windows NT, 2000, and XP
Choose Start, Settings, Control Panel, and double-click System. On
Microsoft Windows NT, select the Environment tab; on Microsoft Windows
2000/XP select the Advanced tab and then Environment Variables. Look if
there's already a User Variables named JAVA_HOME. If not, press button
New and type JAVA_HOME as its name and the directory you established
just before as its value.
2) On Microsoft Windows 98 - To define JAVA_HOME, open the AUTOEXEC.BAT
file and add or change it as follows:
2a) Start the system editor. Choose "Start", "Run" and enter sysedit,
then click OK. The system editor starts up with several windows showing.
Go to the window that is displaying AUTOEXEC.BAT
2b) Look for a line with JAVA_HOME. If you don't have one, add one the
following line
set JAVA_HOME=C:\Program Files\Java\jdk1.4.2_12
where the part following the = should match the directory you
established above.
2c) Use menu File > Save of the system config editor to save the
modified file. Then File > Exit
3) If you're lucky, the JAVA_HOME environment variable is available
immediately. If not, you could try to do the following
a) restart Eclipse
b) logoff and then logon again
c) restart your computer
4) To verify that JAVA_HOME is set, open the command prompt: Start > Run
> and type "command.com" (Win98) or "cmd.exe" (NT/2000/XP) without
quotes. In the command window, type
echo %JAVA_HOME%
The value set in step 1 or 2 should be displayed.
