Questions[classpath](server)

I have installed tomcat 9 on CentOS 7, location is /opt/tomcat. It works. But when I wanted to shut it down and to start it again when I used shutdown.sh in my /opt/tomcat/bin folder, I got the error:

Cannot find /usr/local/tomcat/bin/setclasspath.sh

There is no tomcat folder there. when I use echo $CATALINA_HOME it points to the same /usr/local/tomcat. I've read somewhere that I should change CATALINA_HOME variable in my .bash_profile, should I do that? I can't find that file anywhere.

Do I need to set the environment variable of CATALINA_HOME and how I can do that in Centos?

I'm trying to run a jar that is located at /Library/Java/jack.jar, this works:

java -jar /Library/Java/jack.jar

However, I want to run it without the path, relying on the class path. The default class path includes /Library/Java, but this fails with "Unable to access jarfile":

java -jar jack.jar

Why? What's more, this also fails (same error):

java -cp /Library/Java -jar jack.jar

What's the problem/what am I doing wrong?
Thanks.

I've just been through a lot of grief installing activemq on Debian Wheezy. apt-get install activemq installed a lot of packages - openjdk-jre + a raft of libraries, all of which ended up in /usr/share/java as far as I can make out. With a completely basic config, activemq started up fine, but as soon as I added any authentication or authorization sections to my config, it barfed with a NoClassDefFound error for org.objectweb.asm.commons.EmptyVisitor. This class is definitely provided by /usr/share/java/asm3-all.jar, which is happily installed on my system presumably as a result of the dependencies specified in the activemq package.

So what gives? After a fair bit more digging, it turns out that most of the jars required to operate activemq are also installed directly in /usr/share/activemq/lib - including asm3.jar, but, crucially, not asm3-all.jar, which includes the offending class. As an experiment, I copied the jar from /usr/share/java/ to the activemq lib directory... and it all worked fine.

So my question is: why on earth did the activemq package install 150+MB of jars in /usr/share/java if it actually doesn't use any of them??? In my days as a Java programmer I would have assumed that an java app would just have to bundle all of its dependencies and be done with it, but the fact that activemq pulls in all these libraries as dependent packages seems to suggest that someone thinks otherwise... or is this just a balls up?

I am upgrading an old WLS8.1 app to 10.3 (11g) My ant build includes only the new weblogic.jar in the compile classpath and the build runs with no issues but when I include weblogic.jar as a libeary in the IDE (Intellij) i see many unresolved imports (for example: weblogic.xml.xpath.DOMXPath) when I check the weblogic.jar I see that the classes are indeed missing from it.

compiling with verbose revealed that by including weblogic.jar in the ant classpath, many other jars in the BEA_HOME/modules are loaded to the classpath as well (for example: com.bea.core.xml.weblogic.xpath_1.4.0.0.jar)

Can anyone explain what is going on?

How can I fix my IDE classpath - do I need to import all the module-jars?

Many of the module jars seems like they are there to support old deprecated weblogic 8 APIs (like: weblogic.xml.xpath.DOMXPath) how can I exclude these modules from my ant build? (I want to expose the APIs I need to upgrade)

Thanks,

We have set up Tomcat 6 with

• [TOMCAT_HOME]/lib - here is the standard tomcat release
• [TOMCAT_BASE]/lib - here we like to add non standard additional jar file

However somehow I don't manage to get [TOMCAT_BASE]/lib jar files to be picked up by Tomcat. It appears that all my jar files out side tomcat are ignored.

Before starting Tomcat I set the CLASSPATH=[TOMCAT_BASE]\lib

-------- Edit

JAVA_ENDORSED_DIRS can be used for adding an additional folder with jar files to be loaded by Tomcat
