Tomcat 4 as a service in Windows and Classpath Question
I've recently installed Tomcat 4.1 as a service in a Windows 2000 environment. In Linux, if I ever need to extend the CLASSPATH variable, I can do that easily in the scripts provided. However, I'm not clear how to do this in Windows when Tomcat was installed as a service. What is the correct way to extend CLASSPATH, and if the service needs to be reinstalled, what would be the command in order not to loose the default settings, plus the extra paths? Thanks in Advance.
RE: Tomcat 4 as a service in Windows and Classpath Question
What I've figured out is that you can hack the registry and modify the java.class.path parameter. Alternatively, there is a syntax for installing the service where you can specify the classpath when you install the service (or you could uninstall and re-install). How to hack the registry: use regedit to edit key HKLM\SYSTEM\CurrentControlSet\Services\Apache Tomcat 4.1\Parameters\JVM Option Number 0 (assuming your service is called Apache Tomcat 4.1 and that your JVM Option Number 0 parameter data begins with -Djava.class.path...) Double-click the parameter and edit the classpath at will. How to install a new service: open a command prompt and use syntax %CATALINA_HOME%\bin\tomcat.exe -install Apache Tomcat 4.1 %JAVA_HOME%\jre\bin\client\jvm.dll -Xmx512m -Xms256m -Djava.class.path=%CATALINA_HOME%\bin\bootstrap.jar -Dcatalina.home=%CATALINA_HOME% -start org.apache.catalina.startup.BootstrapService -params start -stop org.apache.catalina.startup.BootstrapService -params stop -err %CATALINA_HOME%\logs\stderr.log (all on one line, and obviously modifying the -Djava.class.path to whatever you need but not losing the bootstrap.jar) If you install multiple Tomcats on one box as services, you will need a different server.xml file for each to specify different ports. I *believe* the syntax for this is to edit the service in the Services control panel, and add an Additional Parameter of the form -config conf\server.xml Hope that helps. If anyone else has more good information, please add.

Classpath Question
Hi, I am using tomcat version 4 as a web service provider. I have 10 web services for my application and they all seem to compile properly. the issue is when I go to run the application I get a java.rmi.ServerException error with a missing port. I am nearly 95% sure that it is a problem with the CLASSPATH in that I dont declare where the class paths are for each application. How do I do this: An example of where the java classes are is C:\tops\classes. I cant move the classes as it is an application in itself and is connected to an oracle database. Please I need the following information? 1 Can this be done at all? Or is my boss nuts? 2 How do I do it?

Re: Classpath Question
I ran against the same problem and found a solution I'm more or less happy with (perhaps someone with more experience can correct me if my solution is crazy.) If you ABSOLUTELY cannot move your classes into %TOMCAT_HOME% \common\classes directory, there is another option: In your %TOMCAT_HOME%\bin\setclasspath.bat file, you can redefine the CLASSPATH variable to include all the important tomcat .jar files plus your classpath. This bypasses the bootstrapper. I.e.: . . set TOMCAT_HOME=c:\tomcat set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%TOMCAT_HOME% \common\lib\activation.jar;%TOMCAT_HOME%\common\lib\mail.jar; %TOMCAT_HOME%\common\lib\ant.jar;%TOMCAT_HOME% \common\lib\commons-collections.jar;%TOMCAT_HOME% \common\lib\commons-dbcp.jar;%TOMCAT_HOME% \common\lib\commons-logging-api.jar;%TOMCAT_HOME% \common\lib\commons-pool.jar;%TOMCAT_HOME% \common\lib\jasper-compiler.jar;%TOMCAT_HOME% \common\lib\jasper-runtime.jar;%TOMCAT_HOME% \common\lib\jdbc2_0-stdext.jar;%TOMCAT_HOME% \common\lib\jndi.jar;%TOMCAT_HOME%\common\lib\jta.jar;%TOMCAT_HOME% \common\lib\mail.jar;%TOMCAT_HOME% \common\lib\naming-common.jar;%TOMCAT_HOME% \common\lib\naming-factory.jar;%TOMCAT_HOME% \common\lib\naming-resources.jar;%TOMCAT_HOME% \common\lib\servlet.jar;%YOUR_CLASSPATH% .

Re: Classpath Question
A problem with the classpath should indicate a classpath related exception, which essentially is an inability to find a class. Why do you think that hte java.rmi.ServerException fits into this pattern? If you don't declare where the class paths [sic] are for each application how do you expect the JVM to find the classes? You sure that is what you mean? At 04:54 PM 3/20/03 +, you wrote: Hi, I am using tomcat version 4 as a web service provider.

Newbie classpath question
Hey, I am using tomcat 4.1. I have placed my jar files in the shared directory as it is required by more than one webapp. Unfortunately, I have two jar files which have the same class files but with different versions. Is there any way to specify which jar file to load the class from without having to write class loaders? Obviously I can remove the class files from the other jar file. But don't want to do that as we might want to move to using the class files in the other file sometime pretty soon. Any help would be greatly appreciated. Thanks, Shiva. __ Do you Yahoo!? Yahoo!

RE: Newbie classpath question
Hi, Basically, no ;) It's your responsibility as a developer to ensure no class file conflicts between your apps and your chosen server. You could do a number of things to reach this: - Modify apps so they use the same version of shared jars - Deploy multiple copies of the jar, all in the WEB-INF/lib directories and not in the shared directories. - Other options exist, but the above are probably the quickest...

En réponse à Shiva P [EMAIL PROTECTED]: The version of the class in the first .jar in the classpath order must be used when tomcat is running.

newbie Catalina and JBoss classpath question!
I'm a student trying to debug a servlet under Catalina (Tomcat 4.0.1) that calls a session bean under JBoss 2.4.3. My servlet dies horribly unable to load (NoClassDefFoundError) javax/ejb/EJBHome which I believe is in jboss-j2ee.jar. The appropriate directory is in my classpath. However by checking the classpath while my servlet executes I note that Tomcat has completely replaced it with its own that has none of my directories or the JBoss jars in it. I can run standalone code that calls the session bean with no problem. What's the appropriate approach to this? Can anybody give me some pointers on this? -- Carl W. Schwarcz
Order of libraries in CLASSPATH question?
We are having random problems with some of our application libraries when we deploy them in their separate contexts. The question I have is what is the default behavior for Tomcat to load class libraries into its CLASSPATH. Do libraries from the $TOMCAT_HOME/lib directory get added to the CLASSPATH before libraries for a particular web application (e.g. webapps/someapp/WEB-INF/lib/*) or viceversa. I have also seen problems where my web application can't find a particular library when it is added to the webapps/someapp/WEB-INF/lib but it can find it when it is added to the $TOMCAT_HOME/lib directory. This particular problem occurred when I tried to use Oracle's jdbc drivers (i.e. classes12.zip). I would get class not found errors when the classes12.zip file was located in the WEB-INF/lib directory, but the errors went away when I used the $TOMCAT_HOME/lib directory. What is the recommended place for putting class libraries in the classpath for Tomcat? Any suggestions would be greatly appreciated. Thanks in advance, Brett

Subject: Order of libraries in CLASSPATH question?
We are having random problems with some of our application
libraries when we
deploy them in their separate contexts. The question I have
is what is the
default behavior for Tomcat to load class libraries into its
CLASSPATH. Do
libraries from the $TOMCAT_HOME/lib directory get added to
the CLASSPATH
before libraries for a particular web application (e.g.
webapps/someapp/WEB-INF/lib/*) or viceversa.
If you look in your %TOMCAT_HOME%/logs/jasper.log file, it will show you the
classpath it is using for each request. In general the effective classpath
for a webapp will be:
WEB-INF/classes/
WEB-INF/lib/*.jar (in aplpabetical order I believe)
%TOMCAT_HOME%/classes (only if using Unix's tomcat.sh)
%TOMCAT_HOME%/lib/*.jar (in alphabetical order, only if using Windows's
tomcat.bat)
%TOMCAT_HOME%/lib/* (in alphabetical order, only if using Unix's tomcat.sh)
System Classpath (in orginial order)
Remember that the classpath is searched from first to last.
I have also seen problems where my web application can't find
a particular
library when it is added to the webapps/someapp/WEB-INF/lib
but it can
find it when it is added to the $TOMCAT_HOME/lib directory.
This particular
problem occurred when I tried to use Oracle's jdbc drivers (i.e.
classes12.zip). I would get class not found errors when the
classes12.zip
file was located in the WEB-INF/lib directory, but the errors
went away when
I used the $TOMCAT_HOME/lib directory.
The automatic loading for the WEB-INF/lib directory only includes .jar files
- its implied from the Spec that other behavior is non-compliant. The
tomcat/lib directory depends on your startup script
What is the recommended place for putting class libraries in
the classpath
for Tomcat? Any suggestions would be greatly appreciated.
You shouldn't edit your classpath for Tomcat - you should put your classes
into the WEB-INF{/lib/*.jar|/classes/} (preferred) or %TOMCAT_HOME%/lib.
Many people will argue that if the classes are common across webapps then
you should use the second one, but I would caution against this as it makes
it hard to upgrade one webapp at a time to new versions of libraries.
Thanks in advance,
Brett

The question I have is what is the default behavior for Tomcat to load class libraries into its CLASSPATH. Do libraries from the $TOMCAT_HOME/lib directory get added to the CLASSPATH before libraries for a particular web application (e.g. webapps/someapp/WEB-INF/lib/*) or viceversa. I believe that the order is: system classes including installed extensions. .zips/.jars in $TOMCAT_HOME/lib WEB-INF/classes WEB-INF/lib/*.jar I have also seen problems where my web application can't find a particular library when it is added to the webapps/someapp/WEB-INF/lib but it can find it when it is added to the $TOMCAT_HOME/lib directory. This particular problem occurred when I tried to use Oracle's jdbc drivers (i.e. classes12.zip). I would get class not found errors when the classes12.zip file was located in the WEB-INF/lib directory, but the errors went away when I used the $TOMCAT_HOME/lib directory. if they were still named *.zip, the classloader ignores them. We just have Ant rename them to *.jar before deploying to webapps/ourapp/WEB-INF/lib, and they work fine. What is the recommended place for putting class libraries in the classpath for Tomcat? Any suggestions would be greatly appreciated. If there is any chance that the Tomcat installation will be hosting more than one webapp, I strongly suggest that you put the libraries for each webapp in its own WEB-INF/lib. Clashing jars do not make pretty sounds.

Classpath Question
I have a question about how the dynamic class path is set based upon the .war file. I know that whatever classpath is set prior to tomcat startup is appended to the classpath in the startup.bat. Furthermore, whatever .jar files that reside in tomcat_home\lib are also dynamically added to the classpath and tomcat_home\classes is also put on the classpath. I have verifed this by call a System.getProperty(java.class.path) from a servlet. What I don't fully understand is how the contents of the .war files \lib path are seen by tomcat since they don't appear when I call System.getProperty(java.class.path). I would really appreicate a bit of clarity on this. TIA, Keith
RE: Classpath Question
the call: System.getProperty(java.class.path) only returns your System class path - the jars in /lib and the classes in /classes are dynamically loaded by a ClassLoader in Tomcat - they do not become a part of your System class path.

Tomcat has its own ClassLoader implementations (in 3.2, org.apache.tomcat.loader.*) which can pull the classes from the webapps directory.

classpath question
[System: Linux, Tomcat 3.2.1, Apache 1.3.19, mod_jk] I have a web app that uses several jar files. I have these in a lib directory that has a symlink in my WEB-INF dir.

classpath question
I have placed a prop.properties file in the WEB_INF/lib directory of my tomcat context. The servlet keep throwing an Exception saying that it cannot find the ResourceBundle. Where should I place this file? From what I have read, the prop.properties file should go into the WEB-INF/lib directory. Where exactly should this file go?? thanks for the help in advance

context related classpath question -ASAP
Title: context related classpath question -ASAP Tomcat documentation says that all the jars under the WEB-INF/lib directory in a context are automatically added to the CLASSPATH. I am finding this not to be true. I have to add them explicitly to the CLASSPATH. Am i missing something ???
Re: context related classpath question -ASAP
I think the startup scripts actually add the .jar files to the CLASSPATH variable. Are you using the normal startup scripts to start Tomcat?

Craig, Thanks for the clarification. I have a servlet to be loaded on startup which is looking for another class.

If so, the best way to get it resolved is to report a bug in the bug tracking system: http://nagoya.apache.org/bugzilla/ and add our test case in the details. The reason I ask for this is that many people do things like what you describe without difficulty -- so there must be something specific about how you are doing this that is different and therefore causes the problem.

RE: ClassPath question?
As far as classpaths are concerned, you can think of a jar file as a directory (not a file). That is, unlike files (.class files especially) you must explicitly specify the jar file on the class path. That is, to pick up the servlet jar file, specify the following path. You will have to do a similar thing for each of the other jar files too. /usr/local/tomcat/lib/servlet.jar - Ck Brainbench MVP Java2. -Original Message- From: Jian Zhang [mailto:[EMAIL PROTECTED]] Sent: 02 February 2001 11:23 To: '[EMAIL PROTECTED]' Subject: ClassPath question?

RE: ClassPath question?
_Normally_ the core java libraries are inserted onto the classpath for you, hence you may not always have to setup a classpath. javax.* is not part of the core libraries, its name actually stands for 'java extensions'. Over time some of these extensions, such as swing (javax. swing) have made it into the normal distribution but others such as servlets have not. If you want to see what is or is not in the core distribution, go into the libs directory of the JVM installation of the JRE and open up rt.jar.. in there you will find java.io, java.util etc etc. - CK Brainbench MVP Java2. -Original Message- From: Jian Zhang [mailto:[EMAIL PROTECTED]] Sent: 02 February 2001 11:51 To: '[EMAIL PROTECTED]' Subject: RE: ClassPath question?
