Hello Jean-Claude,
I don't use the Eclipse IDE. I do all my developments with the NetBeans IDE.
But anyway, the IDE does not matter since Tomcat is running separately in an productive environment under Linux with Apache, mod_jk and Java 1.5_02
Tomcat 5.5 just uses Eclipse JDT compiler classes to compile JSPs. But it should be possible to change the config, so that Tomcat uses another compiler. At least, the releasenotes say so.
But there is no useful howto at the tomcat web site or anywhere else. (at least I didn't find one)
The problem is:
1. Tomcat 5.5 (without compatibility packages) runs only with Java 1.5 (JRE!)
2. The built in Java compiler to compile JSPs (and only JSPs) is the Eclipse JDT Compiler !!! JAVA 1.4 !!!
==> So Servlets using Java 1.5 features are runnig without problems because they are already compiled
==> JSPs with Java 1.5 features cannot be compiled (within tomcat) because the tomcat built-in compiler only knows Java 1.4

Hello
Lutz is right : you may define your JRE under Eclipse Under (sorry for my mistakes : i use a french version and try to translate in english) Window -> Preferences -> Installed JRE you may use an other JRE that the one installed under Eclipse Hope this will help you

Do you integrate the Tomcat 5.5.9 into your Eclipse IDE or do you run it seperately?Hello,
I installed Tomcat 5.5.9 and want to use Java 1.5 in my JSPs. Since Tomcat 5.5 uses the Eclipse JDT Compiler (Java 1.4), it cannot compile my JSPs. So I want the tomcat to compile the JSP's with the Sun JDK 1.5 compiler. I searched the web, but I did not find any instructions how to configure the tomcat to do so.
Can anyone help me?
If you run Tomcat integrated into Eclipse, perhaps you can tell Eclipse which installed Tomcat and which installed JDK to use for your project. This is the way, I can do it with NetBeans IDE.
Else, if you run Tomcat independently of the IDE, you must only set the environment variable for the JDK correctly before starting the server. I am running Tomcat 5.5.7 with JDK 1.5.0_02 and have to set the environment variable JRE_HOME so that Tomcat uses the right one of the installed JDKs. I set the JRE_HOME manually before starting Tomcat:
export JRE_HOME=/usr/java/jre1.5.0_02/ (you must change the path to the path you use on your system)
The environment variable JAVA_HOME could also play a role, although not in my case. :-)
I hope, this information does help a little.
Best wishes
Lutz
