CLASSPATH in TOMCAT

Hi guys!!!
WHat the CLASSPATH I must set, to use the servlets in tomcat container. I use the <JWSDP_HOME>\server\lib\*.jar but don't work!!!!
Thanks.
Giscard

You'll have to provide more information, such as what you're doing to install the servlets, the exact line in the config file you're using (or environment property perhaps?) to set the classpath, and define exactly what "don't work" means. Are there errors on tomcat startup? Errors when attempting to execute the servlet? If so, what are the error messages? If the latter, how are you executing the servlet? If it's not either of these things, then what is going wrong?

Configuring classpath in Tomcat 4.1.12

Hi,
I have an existing system which consists of JSP files and jars running on Tomcat 3.2.1 on Linux 6.1 platform. I have to upgrade it to Tomcat 4.1.12 on Red Hat Linux 8.0. However, now I am having problems in loading the jar files. Before the jars were under a different location than the Tomcat location as also the JSP files. and i used to simply run a script to load the jars on to the classpath, after i start the Tomcat server. However, now in the new system I am not being able to load the jars in the classpath. Tomcat simply won't find the jar files. How do I point Tomcat to the jar location? I would also like to mention here that I am being able to load the JSP files. In the context path, under server.xml, i am pointing the docbase to my application path. Is there any option to point to my classes also here?
I am using a similar context path as below:
<Host name="myapplication.com">
<Context path=""
debug="0"
docbase="/home/opt/myapplication/myfiles"
crossContext="true"
reloadable="true"
trusted="false"
>
Also I am not using WARs
If somebody can suggest any solution it will surely be a great help.
Thanking you in advance,
Regards,
Kaustuv Sharma

or even put links to the jar files in .../common/libhi,
so i put links to the jar files from common/lib in catalina.sh?
coz, i tried this option by editing the catalina.sh file. But I got the following exception: "Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException"
malcolmmc did u mean this?...or is there any other way where i put a link to my jar files in common/lib...?

Classpath in tomcat.bat for jdbc driver (jsp page)

Dear Friends,
I am able to run my java program with Microsoft JDBC driver from console (dos prompt).
But, when i am trying to run JSP program on browser using, the same driver, it is saying classNotFoundException().
do i need to set the classpath for Microsoft jdbc driver in my tomcat.bat ?
Please help me, what changes do i have to do in tomcat.bat to run the microsoft jdbc driver for jsp application.
If anyone having idea, please share ur valuable ideas.
thanks in advance.

If the driver is packed in a jar-file, you can just place the jar in the lib directory of Tomcat. If it's not, you can pack it in a jar and do the same thing:)

Urgent : How to include Win2K CLASSPATH to Tomcat 4.2

I am running a web application on Tomcat 4.1
Tomcat 4.1 uses CATALINA_HOME and JAVA_HOME
enviroment variables and from my knowledge of the settings
it does not utilise the Win2K CLASSPATH variable.
I use a number of *.properties files to access values and variables
so I need to set the startup program of Tomcat to include CLASSPATH.
Is this possible ?
Secondly is there any other way of making the web application recognise
these property files .
Based on some suggestions I tried including the files with classes
and adding a zip file.
It works fine with Tomcat 3.2.4 as it includes CLASSPATH on startup.
Could anyone suggest the solution for this as I searched the Tomcat websites and could not find a solution.
Thanks
manosham

I looked at the Tomcat 4 startup file and it looks like it overwrites CLASSPATH in the bin/setclasspath.bat file. You can get around that by modifying that file. Look for this line near the end:
set CLASSPATH=%JAVA_HOME%\lib\tools.jar... and change it to ...
set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%CLASSPATH%Hope that helps :)

How to edit CLASSPATH in TOMCAT?

Hello...
How can I access my classes in my JSP file if I use Tomcat?
I have put classes12.zip in my classpath (my java console
application recognized the classes). But my JSP (through
TOMCAT) cannot recognized the classes.
Please help.
Thank you.

Tomcat generally ignores the CLASSPATH environment variable. Typically shared classes are copied to TOMCATHOME/lib (ZIPs and JARs)
I've heard from many peer developers not to use zip but to rename them to JAR. Not sure why though; I've had success using both.

Setting classpath in Tomcat on AIX

Hi All
Can any one know how to set classpath for jsf application in tomcat on AIX.

Refer to the Tomcat's documentation regarding classpaths and classloading. The underlying operating system doesn't really matter.

Setting Classpath in TomCat 5.5 for Custom Application

I seem to have messed up my application. I cant access some of my java classes written and deployed in the WEB-INF/classes directory from a JSP Page stored in my app root.
However, the fun part of this is if I create a package in WEB-INF/classes, store my java/class files in it and access these from the JSP using import, it works pretty fine. I'm unable to debug the scenario.
I've given only the context path for the application in the server.xml. I suppose that would be sufficient for my application to be deployed, and need not specify any other classpaths anywhere.
Please help me and correct me if i'm wrong.
fun_one

As of Java 1.4, if any class is in a package, then it can no longer access or import classes from the default (non) package.
As of Tomcat 5.0, all TC classes, including the translated JSP pages, are in a package. That means that they can not access your classes that are not in a package.
Your only option is the best one you should always do anyway: put all the classes in a package.

How can I add classpath in tomcat 4.0.3

I am sorry to ask a newbie question but I am really dying to know the answer.
I have tomcat4.0.3 installed and working.
I have j2ee1.3.1 install and working.
I have jboss3.0.0RC installed and working.
now I want to use a EJB in tomcat application,
the source file compile correctly.
but I type http://192.168.100.24/tomcat/servlet/FirstServlet
a ServletException throwed,tomcat complain javax.ejb.EJBHome class
cannot be founded.
I think it is a problem about classpath.but the environment variable
classpath has included j2ee.jar and when I use j2ee to develop an
web application I have never met such case.later I found a article
says tomcat4.0.3 don't use system classpath.
then I found a file named setclasspath.bat in bin directory,
and I change the line 'set CLASSPATH=%CLASSPATH%' to
'set CLASSPATH=%CLASSPATH%;%J2EE_HOME%\lib\j2ee.jar'
but the tomcat cannot startup.
how should I do.
BTW,how to get the information about tomcat fail to startup

Throw your j2ee.jar into the WEB-INF\lib directory of your web app module. The servlet should pick it up there.

Setting classpath in Tomcat

I can compile a Servlet that imports javax.servlet.http package through the command prompt. But when I try to access this class through Tomcat I gives an error, saying that it could not find the javax.servlet.http package.
Doesn't Tomcat takes its classpath from the environment variable CLASSPATH, i.e., does it has it 's own classpath variable?

Of course it doesn't. Thanks for the semantic
correction, though. np! ;o)
What I meant is that Tomcat 4 does
not use the system classpath by default.No, you're right. I just checked my test-bed install and it has all the J2EE jar's it needs (inc. servlet.jar) in CATALINA_HOME/common/lib . I think that is the tomcat classloader's first port of call so it must load from there. OP, I think you have deployment issues. Try reinstalling tomcat, or possibly copying your J2EE jars to CATALINA_HOME/common/lib . I don't know if the copy will work, as I know that having things there that don't need to be there can cause big problems. Take your pick.

F.S

It seem the required class files are not set in the tomacat classpath.im not sure which version of tomcat u are using.add the corresponding javamail jar files (including activation framework)in ur machine and set classpath accordingly.
HTH.

Classpath and Tomcat 4.0

I need to add a jar to the classpath, and I don't know how to do that....I'm new to all this, so please be very detailed in guiding me.
I use Tomcat 4.0 on win2000.

To add a jar file to the classpath follow the following instructions
1. Windows system:
a. Go to Control Panel - System - Select the Advanced Tab.
b. Click on the Enviroment variables Button. This will throw up a window with a lot of predefined variables. The classpath varible must be one among these. If it is there select it and press edit other wise select add.
c. To add the jar file place a ";" at the end of the previously stored value and enter the full path to the jar file like this c:\dir1\dir2\Jarfile.jar
Alternately for the windows system you can add the following line to the autoexec.bat file in your c:\ drive or any .bat file which is to be run before your application
set classpath=c:\dir1\dir2\Jarfile.jar;%CLASSPATH%
2. For Unix System:
a. If you are using C shell look for the .cshrc file or .cshrc.user file to add the jar file to the classpath, similarly if it is k shell look for .kshrc or .kshrc.user file to add the path . Note that the entries in Unix are seperated by ":"
Keep me posted
Good Luck!

How to config the CLASSPATH for Tomcat 4.0???

I use a JavaBean in a JSP file. And I use this JavaBean to connect to Oracle. Database username and password is stored in a file named "db.properties". When I browse this JSP page, It report : Cant not find db.properties file!!!
So I want know is where can I put this "db.properties"??Do I need config CLASSPATH or other para??
need your help!!
Thanks in advance!!!

did you try to put it into the /lib/ directory of your webapplication ?
I would solve this differently, I would create a servlet that takes initial parameters and puts them into the servlet context. then I would use that to put these information into the servletcontext.
Then you would not have to load a properties file everytime u access the jsp pages that does the database related procedure.
Maybe there is some place for system properties files, but this place I have not seen or how to work with it.
I place my configuration files all under web-inf/config/ and then I mapp paths to it and read as the web application starts.
hope it helps.

Set up the classpath for tomcat 5.0 to compile servlet

I am totally confused how do you set up the class path, i use this command:
c:\set CLASSPATH=.;C:\tomcat5.0\common\lib\servlet-api.jar;%CLASSPATH%
and I compile my file which i put in j2sdk1.4.2_10\bin
here is the command line:
c:\j2sdk1.4.2_10\bin\servletexercise1.java
and it gives me the error message to say that it can't find the servelt, javax.servlet.
Please help! thanks in advance!

I am totally confused how do you set up the class
path, i use this command:
c:\set
CLASSPATH=.;C:\tomcat5.0\common\lib\servlet-api.jar;%C
LASSPATH%I don't have a CLASSPATH environment variable on any machine that I work with.
and I compile my file which i put in j2sdk1.4.2_10\binThat's a pretty stoopid place to put a Java source file. You shouldn't be putting any files in that directory.
The right thing to do is to add the Java /bin directory to your PATH environment variable. When you do, make sure there are no spaces in the path name. (e.g., don't install Java to the "Program Files" directory) OR replace it with its 8-char DOS equivalent (e.g., c:\Progra~1).
here is the command line:
c:\j2sdk1.4.2_10\bin\servletexercise1.javaSorry, I don't see where you execute javac.exe.
and it gives me the error message to say that it
can't find the servelt, javax.servlet.
Please help! thanks in advance!What is this telling you? That the javac.exe totally ignores the CLASSPATH that you set? (Hint: Right answer.)
The correct way to do it is to use the -classpath option on javac.exe.

Tomcat Installation and setting Java Classpath

Please help me in setting up Java classpath for Tomcat Server. I am unable to start the Server itself.

try this it worked for me..install Tomcat and Ant in 2 seperate directories, if you are win98 or less edit your autoexec.bat file and set the class paths as follows
set PATH=C:\jdk1.3\bin;%PATH%
set ANT_HOME=C:\Ant
set TOMCAT_HOME=C:\Tomcat
set JAVA_HOME=C:\jdk1.3
If you are using windows 2000 or NT you have to goto control panel --> system --> advanced and click environment variables
for name type in say TOMCAT_HOME and for value type in c:\Tomcat
restart your computer.
Then goto tomcat\bin and type startup....in a browser type in http://localhost:8080 and you are in
hope this helps

Setting .jrxml in tomcat classpath

Hi,
I am using Jasper reports to build a HTML document. In my code i dont want to specify the absolute path of the .jrxml file for the tomcat server to recognize.
Hence, in my code i want to use "contact.jrxml" instead of "c://contact.jrxml", simillarly for the generated .html as well where i should not specify the destination of .html with absoulte path. When i am using the absolute path tomcat is picking it up and generating the html. But when i give only the filename like "contact.jrxml" it is unable to find that, i have set the .jrxml file directory in Tomcat class path in eclipse. But still it is not able to pick it up. What may be the problem? Please do mention how to place the .jrxml and .html in classpath of tomcat? So that the server can pick it up with throwing an error. I tried copying the files in "webapps" and "bin" directory of tomcat but it didn't work as well. Hence, please do provide a solution for this.
Thanks,
Rithu

Generally, in web technology,
create a folder for user friendly in side yourwebapp/jrxml folder
store all your .jrxml file there
try with relative path,
or
keep path in the .properties file
and while your webapp load, keep loading this configuration file and store in a property and use it where ever you need.
