[opencms-dev] Installation issues - Incompatible compiler& JRE

[cherif]

hello Paul D and Ethan,

Sorry if i send 2 times and my english!!

Ethan, there is no silly question, no body can claim to know everything. So
you are rigth to post your problem.

The JDK is basically a JRE plus a compiler so you can compile and run java
programs yes ?
Because Tomcat needs a compiler to process JSP pages, you MUST download the
JDK, yes?

jsp = java server pages

basically opencms Installation issues (on unix system and my own experience,
don't know about  windows) is coming from:
----->bad PATH setting :java classes can't be found(e.g javac, even java) or
other needed resources.
----->bad combination of versions (jdk version, jsp specification
level(tomcat version),  mysql version ..)
keep on mind that tomcat version 4.x =  servlet 2.3 specification - jsp 1.2
specification
    tomcat version 5.x =servlet 2.4 specification - jsp 2.0 specification
etc....

Please try to be sure gatering and "combining" the rigth pieces

I think Paul is rigth you are having incompatibility problem

You have installed your JRE via RPM, then before installing the jdk, did you
remove your JRE RPM instal  ? (rpm -e .....)

Can i suggest : jdk-1.5_0_03-linux-i386.bin, jakarta-tomcat-5.5.9.tar.gz,
MYSQL-server-4.1.11-0.i386.rpm,MYSQL-client-4.1.11-0.i386.rpm,mysql-connecto
r-java-3.1.8a.tar.gz those what i am using on fedora core 3 (think should
work well on fc2)
generally i don't like spanding too much time in deburging, very stressing,
often trying to find the good combination as i describe is far more quiker..

I stay watching

Regards
