Java Forum / General / March 2006I cannot start TomCat
Dear All, I am using Linux. I have installed J2EE SDK 1.4 at /opt/SUNWappserver. And I have installed Tomcat at /opt/tomcat In root mode, I added following lines to /root/.bashrc export JAVA_HOME=/opt/SUNWappserver export CATALINA_HOME=/opt/tomcat export PATH=$PATH:/usr/local/genesis:$JAVA_HOME export CLASSPATH=$CATALINA_HOME/bin/bootstrap.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/common/lib/servlet.jar:/usr/local/pgsql/share/java/postgresql.jar:../lib/struts.jar:. When I try to fire up TomCat: [root@cng1 tomcat]# ./bin/startup.sh Using CATALINA_BASE: /opt/tomcat Using CATALINA_HOME: /opt/tomcat Using CATALINA_TMPDIR: /opt/tomcat/temp Using JRE_HOME: /opt/SUNWappserver [root@cng1 tomcat]# Open a web browser in http://localhost:8080. No! TomCat is not running. What are my problems? Thank you very much. > Dear All, > [quoted text clipped - 9 lines] > export > CLASSPATH=$CATALINA_HOME/bin/bootstrap.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/common/lib/servlet.jar:/usr/local/pgsql/share/java/postgresql.jar:../lib/struts.jar:. it can be a bit confusing to specify the current and the parent directory when you are defining the classpath in the bashrc. I'm not sure the struts.jar will be found > What are my problems? Thank you very much. Did you check the log file? I believe you will find your answer there > Did you check the log file? I believe you will find your answer there Thank you very much. The log file contains repeated following line: /opt/tomcat/bin/catalina.sh: /opt/SUNWappserver/bin/java: No such file or directory In fact, this is Java part I am not clear: I have installed Java a couple years ago. It is located in: /usr/JAVA/j2sdk1.4.2/bin/javac I just installed J2EE 1.4 SDK yesterday. Taking default locations, it is located in: /opt/SUNWappserver [root@cng1 opt]# echo $JAVA_HOME /opt/SUNWappserver Shoule I set JAVA_HOME = /usr/JAVA/j2sdk1.4.2 ? Is that bad practice to put javac and J2EE in different folders? How should I clean up? Many, many thanks! Thank you all! I got my TomCat running now! I think my fix is adding following line in /root/bashrc file: export $JAVA_HOME = /opt/SUNWappserver/jdk (I don't know why, somebody's tutorial set $JAVA_HOME = /opt/SUNWappserver/, which makes TomCat cannot find java) I will think out running Tomant not as root, later. Thanks! > Is that bad practice to put javac and J2EE in different folders? How > should I clean up? javac comes with the JDK, which is diffferent from the J2EE SDK. You can also download a bundle J2EE/JDK, but I have personally never done it. I prefer to use a separate JDK, to be a bit more flexible, for example when I have to download an update. Actually, I usually don't even download J2EE directly, I prefer to use the jars that come with the server I use (usually JBoss). Anyway, keep in mind that you might need JDK 5 to run Tomcat, depending on the version you have, so your 1.4.2 might be not enough. If you have a version of Tomcat that runs with 1.4 then setting JAVA_HOME to /usr/JAVA/j2sdk1.4.2 is enough. Otherwise you will have to use a new version of the JDK, either downloaded separately or the one that comes with the J2EE SDK (I don't know how). > Many, many thanks! you are welcome Leo <xxx@nospam.com> said: >> Did you check the log file?

Taking default locations, it is >located in: >/opt/SUNWappserver Ok, do you really need this? Do you really need this now? If not, just throw it away and take smaller steps. Tomcat doesn't need it. >Shoule I set JAVA_HOME = /usr/JAVA/j2sdk1.4.2 ? Yes. >Is that bad practice to put javac and J2EE in different folders? How >should I clean up? No, that's how they should be - if you need the J2EE in the first place. Take small steps, read tutorials and documentation. And log files. Btw, why do you run all that as root? It's an unnecessary security risk. Both in the sense of outsider threats, but also working as root you yourself have much better possibilities to have a simple mistake turn into a disaster.
