Tomcat variable

Dear Friends,
Tried to start tomcat, environment variable needed to run this program.
Comments, please
C:\cat\jakarta-tomcat-4.1.29\bin>startup
The JAVA_HOME environment variable is not defined
This environment variable is needed to run this program
Using CATALINA_BASE: ..
Using CATALINA_HOME: ..
Using CATALINA_TMPDIR: ..\temp
Using JAVA_HOME:
The system cannot find the file -Dsun.io.useCanonCaches=false.
C:\cat\jakarta-tomcat-4.1.29\bin>

So? The error message tells you exactly what you need to do, isn't it? Set the JAVA_HOME environment variable.
Read the installation instructions of the Java SDK. You must set JAVA_HOME to point to the installation directory of the Java SDK (for example, C:\j2sdk1.4.1_01, or wherever you have installed it).

Reading a global variable from tomcat with JNDI. Example not working

Hi you can help me to make this example work?
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup("java:comp/env");
Object o = envCtx.lookup("testvariable");
<GlobalNamingResources>
<Environment name="testvariable" type="java.lang.Boolean" value="false"/>
Nice greetings Christian

I found out that in addition to having the JNDI lookup code, you have to
- have the environment variable declared in the app server configuration
- have a resource-env-ref entry in your webapp module
- have the application container bind your named variable with the global variable
I am using tomcat 5.5, and have done the following. with success.
the following example uses the default sample environment variable in the tomcat server.xml
in tomcat server.xml:
<GlobalNamingResources>
<Environment
name="simpleValue"
type="java.lang.Integer"
value="30"/>
</GlobalNamingResources>
in my application's web.xml:
<resource-env-ref>
<description>Test read resource environment variable</description>
<resource-env-ref-name>simpleValue</resource-env-ref-name>
<resource-env-ref-type>java.lang.Integer</resource-env-ref-type>
</resource-env-ref>
in my META-INF/context.xml (or otherwise, in tomcat's context deployment configuration)
<ResourceLink name="simpleValue" global="simpleValue"
type="java.lang.Integer"/>
Note: in theory, the named resource by your web app could be different from the global environment variable, but here they are the same 'simpleValue'
This is the really important step, that with out it, nothing works.,
the context.xml is known to work with tomcat when it exists in META-INF/context.xml inside the .war file (i use war files to deploy, but you should be able to create META-INF/context in an unpacked webapp directory too, and tomcat will find it.,
I can not say what it is like for other app servers, but this mapping step is the critical point that i discovered after A LOT of hair pulling.
then, make use of it, i created a jndiTest.jsp:
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.naming.InitialContext" %>
<%@ page import="javax.naming.NamingException" %>
<%
try {
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:/comp/env");
Object o = ctx.lookup("simpleValue");
%>
<%=o%><br>
<%
catch (NamingException ex) {
System.err.println(ex);
%>
since my server.xml defines the value for 'simpleValue' to be 30, this page displays 30

How to set new Tomcat Environment variable?

I have an imported class used by my servlet that is supposed to look for an environment variable like "xxx.app.logdir". I'm having trouble setting it in Tomcat. I have tried the following (stopping and starting Tomcat with each change):
1) In \conf\server.xml file, adding under <GlobalNamingResources> <Environment name="simpleValue" type="java.lang.Integer" value="30"/>
<Environment name="xxx.app.logdir" type="java.lang.String" value="C:\\Tomcat-4-1\\logs"/>2) In my app's web.xml file <env-entry>
<env-entry-name>xxx.app.logdir</env-entry-name>
<env-entry-value>C:\\Tomcat-4-1\\logs</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry> 3) In my \bin\startup.bat file
set xxx.app.logdir=C:\\Tomcat-4-1\\
4) On my PC's Environment variables.
Nothing has worked. In my code I have the lines
logMsg("System.getProperty('mmm.app.logdir')=" +
System.getProperty("xxx.app.logdir"));
logMsg("System.getProperty('simpleValue')=" +
System.getProperty("simpleValue")); with the output :System.getProperty('xxx.app.logdir')=null
System.getProperty('simpleValue')=null I've searched forums and the Tomcat docs, but no luck. Any ideas?

I tried that as well, but maybe I didn't define my DefaultContect correctly. Do I need any other parameters? Couldn't find it in the Tomcat docs. <DefaultContext>
<Environment name="matt" type="java.lang.String" value="value1" />
</DefaultContext>My new code (I simplified the variable name for testing):
System.out.println("System.getProperty('matt')=" + System.getProperty("matt"));
System.out.println("System.getProperty('MATT')=" + System.getProperty("MATT"));Results:
System.getProperty('matt')=null
System.getProperty('MATT')=null

How to set environment variables for Tomcat on mac osx 10.8.5

How do I set up my environment variables - JAVA_HOME and CATALINA_HOME on my iMac running mac osx 10.8.5?

You need to create a setenv.sh script in the tomcat bin directory. The link is an example that you will need adjust- http://www.unidata.ucar.edu/software/thredds/current/tds/tds4.2/tutorial/Getting Started.html

Are there application context variables on WebAS like in tomcat?

Hello @ all,
can anyone tell me if there is a possibility to store variables in an application context on WebAS like in tomcat.
I need this possibility to implement a connection pooling on a server wide basis. Where i thought of implementing a singleton to do the connection pooling and i wanted to store this in the application context of WebAS if there is one.
Any hint or link to documentation would be very welcome.
Thanks
Tobi

Hi,
Since you are in the portal forum, I assume you have a portal installed.
You can then create a portal service, which will function as a singleton for the application server. Note however that if you run a cluster of many application servers, each of them will have an instance of it.

Any Help you can give would be greatly appreciated, what I need to do is cycle through code01, code02....code15
and use the string to do it, but use a counter integer to create the string, ie..'code0' + i and then use the sting to access
on of the member properties in the been...(Code01, Code02) ertc.
If I simply do a
<jsp:getProperty name='Input property='code02'/>
everything works great.
when I try to replace the property='code02' with a variable, so that I can run through a loop, I run into the problems
Any ideas would be of great help as I am pounding my head against the brick wall

How to Authenticate a J2EE application running on Tomcat & Apache with OAM

Hi All,
Can somebody point me to docs which states how to integrate a J2EE software deployed on Tomcat(AppServer) & Apache(WebServer).
I have Oracle Access Manager installed I need to enable SSO for that software.
Thanks,
RK

HI ,
Apart from the installation webgate and protection of the resource through OAM policies, you also need to modify your Java based application.
As a part of integration what OAM do is, it weill pass the user information(eg user id etc) to the Java application as the header variables. And now you have to modify this application so that it will accept the user information send by OAM, also login page if any of the application is disabled.
Also if you are going for cookie based approach, your landing jsp of java application should be capable of reading and validating obssocookie set by OAM.
Hope this will help you.
Thanks,
Ankit

Streaming CSV via Apache/ Tomcat with Mod Proxy

I have Apache hooked up to Tomcat using mod_proxy and attempts to stream a CSV file from a Struts action via tomcat fails.
Using the tomcat port localhost:8080/testappp the streaming works fine but for some reason it does not work via the apache url
Build is Red Hat Enterprise Linux AS release 4 on Apache 2.0.52-25 and Tomcat 5.5
Below are pastes of the apache conf file and tomcat server.xml
Thanks
# httpd.conf
# Based upon the NCSA server configuration files originally by Rob McCool.
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about
# the directives.
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do not begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "/etc/httpd" will be interpreted by the
# server as "/etc/httpd/logs/foo.log".
### Section 1: Global Environment
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
# Don't give away too much information about all the subcomponents
# we are running. Comment out this line if you don't mind remote sites
# finding out what major optional modules you are running
ServerTokens OS
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation
# (available at <URL:http://httpd.apache.org/docs-2.0/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
# Do NOT add a slash at the end of the directory path.
ServerRoot "/etc/httpd"
# PidFile: The file in which the server should record its process
# identification number when it starts.
PidFile run/httpd.pid
# Timeout: The number of seconds before receives and sends time out.

# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.

How do I set miminum # of connections for pool with Oracle and Tomcat?

Hi,
I can't seem to find any attribute to initialize the number of connections for my connection pool. Here is my current context.xml file under my /App1 directory:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1" />
</Context>
I've been googling and reading forums, but haven't found a way to establish the minimum number of connections. I've tried all sorts of parameters like InitialLimit, MinLimit, MinActive, etc, with no success.
Here is some sample code that I am testing:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xxx");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
rst = stmt.executeQuery("SELECT username, server from v$session where username is not null");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; Server: " + rst.getString(2);
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
I'm using a utility to repeatedly call a JSP page that uses this class and displays the message variable. This utility allows me to specify the number of concurrent web requests and an overall number of requests to try. While that is running, I look at V$SESSION in Oracle and occassionaly, I will see a brief entry for app1 or adavey depending on the timing of my query and how far along the code has processed in this example. So it seems that I am only using one connection at a time and not a true connection pool.
Is it possible that I need to use the oci driver instead of the thin driver? I've looked at the javadoc for oci and the OCIConnectionPool has a setPoolConfig method to set initial, min and max connections. However, it appears that this can only be set via Java code and not as a parameter in my context.xml resource file. If I have to set it each time I get a database connection, it seems like it sort of defeats the purpose of having Tomcat maintain the connection pool for me and that I need to implement my own connection pool. I'm a newbie to this technology so I really don't want to go this route.
Any advice on setting up a proper connection pool that works with Tomcat and Oracle proxy sessions would be greatly appreciated.
Thanks,
Alan

Well I did some more experiments and I am able to at least create a connection pool within my example code:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
boolean cache_enabled = ds.getConnectionCachingEnabled();
if (!cache_enabled){
ds.setConnectionCachingEnabled(true);
Properties cacheProps = new Properties();
cacheProps.put("InitialLimit","5");
     cacheProps.put("MinLimit","5");
cacheProps.put("MaxLimit","10");
ds.setConnectionCacheProperties(cacheProps);
          conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xyz");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
//rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
rst = stmt.executeQuery("SELECT user, SYS_CONTEXT ('USERENV', 'SESSION_USER') from dual");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; sys_context: " + rst.getString(2);
message += "; Was cache enabled?: " + cache_enabled;
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(OracleConnection.PROXY_SESSION); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
In my context.xml file, I tried to specify the same Connection Cache Properties as attributes, but no luck:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1"
ConnectionCachingEnabled="1" MinLimit="5" MaxLimit="20"/>
</Context>
These attributes seemed to have no effect:
ConnectionCachingEnabled="1" ; also tried "true"
MinLimit="5"
MaxLimit="20"
So basically if I could find some way to get these attributes set within the context.xml file instead of my code, I would be a happy developer :-)
Oh well, it's almost Miller time here on the east coast. Maybe a few beers will help me find the solution I'm looking for.

Problem with jsp and tomcat

Hi ,

but i already set up the java compiler though i m getting this error. please help me.

You say you have set up the environment variables, but it is not working. You may have them set to the wrong thing. One common mistake is to point JAVA_HOME at the java/bin directory rather than just the /java directory.
Another set of eyes finds small mistakes in the variables that you might not spot yourself.
So please, post:
The values of these environment variables
The path to where the products are installed on your system (ie is it c:\java or c:\j2se1_4_2 or c:\program files?
I would take another close look at that JAVA_HOME variable to make sure of it :-)
Good luck,

JNI and Tomcat

I am trying to use a JNI library on Tomcat. I have created a class with a JNI API. I have tested its use being calling it from a Java application. It works. When I try to invoke it from my app server (Tomcat), I get a java.lang.UnsatisfiedLinkError exception. I must find a way to specify where the library is located, but haven't found how to do this. I have tried to add a -Djava.library.path=... option in the JAVAOPT environment variable in the shell where I run the catalina.sh script, but this didn't help.
Any advice?

If you are using tomcat over UNIX, you shold put the LD_LIBRARY_PATH pointing the path of your native library.
