Using jndi.properties
How can I use a jndi.properties file for JBoss within JDev? I haven't deployed one before and I'm not sure where it should go within JDev. Thanks.
At home, this works for me:
c:\jboss-3.2.3\server\default\conf
and then add to your classpath

Using jndi.properties with weblogic 6.1
Apologies if this is a basic question - I am new to Weblogic.
I have successfully got a test EJB working with Weblogic 6.1 using a properties object to set up my JNDI InitialContext.
In the weblogic examples I've downloaded it says you can also use a jndi.properties file to do this. I have set up a jndi.properties file, which is in the classpath for my class calling the EJB. But when I do my jndi .lookup("ejbname") I get the error:
javax.naming.CommunicationException: Can't find SerialContextProvider
The weblogic documentation at:
http://e-docs.bea.com/wls/docs61///rmi_iiop/API_rmi_iiop.html
refers to using jndi.properties and says to look at:
http://edocs.bea.com/wls/docs61/jndi/jndi.html
But at this page there is no mention of the jndi.properties method.
I'd be grateful for any suggestions - in particular whether it is possible to use this method of configuring the JNDI setup.
I'm running wlserver6.1 on a Windows 2000 PC, using JDK 1.3.1
My jndi.properties file looks as follows:
java.naming.property.names=java.naming.factory.initial,java.naming.provider.url
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://localhost:7001It is not WebLogic-specific. See
http://java.sun.com/j2se/1.3/docs/api/javax/naming/InitialContext.html

Calling package from java using JNDI properties
Hi there,
I have created an interface to transfer data from oracle to JMS XML Queue. It is inside a package and have generated a scenario.
The scenario works well when executed from the ODI designer. When I execute it from java it throws an error. The error is
java.sql.SQLException: Cannot load connection class because of underlying exception: 'javax.jms.JMSException: Cannot create the initial JNDI context
Is there any ways to set the JNDI properties, (any set methods for ODIConnection object)
CheersAre you serious with that question? Did you try to build the web service client before? Because this is exactly the same. Try to find "building web service clients" instead "Calling BPEL from java". By default (probably) every BPEL process has both WSIF and SOAP end points, just use correct WSDL address.

Jndi.properties - javax.naming.NoInitialContextException
hi
i'm new to netbeans (5.5) and the Sun 9 appserver. I've been using JBoss & Eclipse to date.
I'm getting the javax.naming.NoInitialContextException and I believe it's because I'm not using jndi.properties like in jboss.
The problem is that I cannot seem to find where it should go and what it should look like.
Can someone please help ?
ThanksAll the documentation you need is here:

Hi All,
I am using OC4J application server 10.1.3.1.0.
my application is standalone application(thick client).
to get the lookup of remote application.
we are using jndi.properties as follows .
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=opmn:ormi://ipaddress:6005:group/application,opmn:ormi://ipaddress:6006:group/application
java.naming.security.principal=myusername
java.naming.security.credentials=password1
oracle.j2ee.rmi.loadBalance=lookup
Now i want one clarification that can i able to encrypt the username and password for security purpose because every client machine is able to see this properties.
if yes can u suggest the solutions ASAP.
thanks in advance

Jndi.properties for WAR trouble
Hi All.
To access a remote enterprise bean, I have to populate the required JNDI properties in my web-tier code, when creating the context.
Trouble how to do this using jndi.properties file ? When I append path of file to CLASSPATH obviously it works (tested using simple session client) but when I deploy my war – properties file is invisible for my delegate. So question : How to include jndi.properties file in classpath for that WAR, or where I have to place it ?InitialContext takes care of that already.
Do you use InitialContext to connect to your own components in the same container too? If so, specify the content of jndi.properties explicitely.

Passing a login and password while using JNDI for RT jobs
Why can we not pass a user name and password when using JNDI for Real Time jobs? Can it be passed in the URL line or somewhere else that I'm missing? This is frustrating as we actually have to connect using Anonymous with no password which opens up so many security holes that we simply can't go to production with this. Please advise.
you can set the login using the JNDI properties file and create the file in the classpath, but again the password will be in plain text
please file a case with Support I think this can be added to JMS adapter operation (user credentials) -

I need to connect to a database I have specified the driver class and url in a .properties file, I have placed this .properties file in the classes folder of WEB-INF
once i create the war file and sent it to the client, They need to change the url but since we are delivering a war file they cannot do it. How can i achieve this?Use a JNDI datasource so that your code doesn't make a connection to the database but uses JNDI to locate the datasource. Then the client only has to create the datasource at the server level and assign it to the JNDI name.

PI 7.11 JMS adapter using JNDI weblogic server issue
Hi SAP experts,
I have a scenario to integrate to a application using JMS adapters. we use SAP PI 7.11 version.
We have deployed JMS drivers successfully and We face issue here to connect to weblogic server
We are using JMS adapter using JNDI to connect to weblogic server version 10.3.
Can anyone help with the exact format to be used in JMS properties table and additional parameters table in JMS communication channel. Your quick help will be appreciated.
A channel error occurred. The detailed error (if any) : com.sap.aii.adapter.jms.api.connector.ConnectorException: Error looking up destination: AccrualDetailsQueue for profile: ConnectionProfile of channel: CC_SND_JMS on node: 3010950 having object id: 673696a9fe8c39fdab32213f0930afb3: javax.naming.NameNotFoundException: Unable to resolve 'AccrualDetailsQueue'. Resolved ''<br> at com.sap.aii.adapter.jms.core.connector.JndiConnectorImpl.createDestination(JndiConnectorImpl.java:168)<brHi Padmini,
Refer to the following link:
http://help.sap.com/saphelp_nw04/helpdata/en/24/4cad3baabd4737bab64d0201bc0c6c/content.htm
It was very helpful to me, for configuring the additional parameters in the communication Channel JMS.
I leave you some screenshots of the settings that I did.
I seize the opportunity to ask you, where do I can get the drivers (.Jar) for Weblogic?
Regards.

AuthenticationFailedException when using JNDI and JavaMail with SMTP auth
Hi all - I've been banging my head on this one for awhile now - hopefully someone else has done this.
We are working in a servlet container (tomcat), and need obtain a mail session from JNDI. We do this as follows:
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
Session mailSession=(Session) envCtx.lookup("mailSession/trumpetinc");so far so good. The jndi entry for the mail session is configured in server.xml as follows:
<Resource name="mailSession/trumpetinc" scope="Shareable" type="javax.mail.Session"/>
<ResourceParams name="mailSession/trumpetinc">
<parameter>
<name>mail.smtp.host</name>
<value>mail.server.com</value>
</parameter>
<parameter>
<name>mail.smtp.password</name>
<value>ABCDEFG</value>
</parameter>
<parameter>
<name>mail.smtp.user</name>
<value>trumpet_kevin</value>
</parameter>
<parameter>
<name>mail.smtp.auth</name>
<value>true</value>
</parameter>
</ResourceParams>With the above, whenever we hit Transport.send(msg), we got an AuthenticationFailedException thrown. I have run into this before with SMTP authentication, so I decided to try using the transport.sendMessage() method instead.
So, I get the transport:
Transport trans = mailSession.getTransport("smtp");
trans.connect();Then I send my message using:
msg.saveChanges();
trans.sendMessage(msg, msg.getAllRecipients());and finally, I close the transport:
trans.close();Unfortunately, I'm still getting the exception. Is it possible that my connect() method is not picking up the JNDI properties set in the server.xml file (this seems likely)? If so, what's the best way for me to get those properties so I can set them explicitly in the connect() method?
Thanks in advance,
- KevinHi,
I have faced the same problem and after some googling and trying I have discovered what causes the AuthenticationFailedException exception. I just wanted to share the knowedge maybe it will be helpfull to others.
Here it is what the API says:
To use SMTP authentication you'll need to set the mail.smtp.auth property (see below) and provide the SMTP Transport with a username and password when connecting to the SMTP server. You can do this using one of the following approaches:
1.Provide an Authenticator object when creating your mail Session and provide the username and password information during the Authenticator callback.
Note that the mail.smtp.user property can be set to provide a default username for the callback, but the password will still need to be supplied explicitly.
This approach allows you to use the static Transport send method to send messages.
2.Call the Transport connect method explicitly with username and password arguments.
This approach requires you to explicitly manage a Transport object and use the Transport sendMessage method to send the message. The transport.java demo program demonstrates how to manage a Transport object. The following is roughly equivalent to the static Transport send method, but supplies the needed username and password:
Using the Transport.connect makes the JNDI not very helpfull for configuration.
It seems that using just the mail.smtp.user and mail.smtp.pass is not sufficient for the authentication.
so, the solution is :
just place these to lines in the JNDI configuration:
username="test"
password="test1"
so it should looks as follows:
<Resource name="mail/Session" auth="Container"
type="javax.mail.Session"
username="test"
password="test1"
mail.transport.protocol="smtp"
mail.smtp.auth="true"
mail.smtp.host="localhost"
mail.smtp.port="25"
mail.smtp.user="test"
mail.smtp.password="test1"
/>
where test and test1 are the user's credentials

Application specific key-value pairs in jndi.properties
Hello,
Can I specify my application specific key-value pair in jndi.properties?
I tried something like this
java.naming.factory.initial=.jndi.WLInitialContextFactory
java.naming.provider.url=t3://localhost:7001
myVar=myVal
When i tried looking up "myVar" from my client program, I got an error.
The other parameters like weblogic.jndi.WLInitialContextFactory are picked up.
Anyhelp will be appreciated
VasimWe have a similar problem.
We would like to configure our PROVIDER_URL for a specific web application - not
for the entire server. Since the URL should be different in development, test
and production environments, we would prefer to just set it in the deployment
descriptor. And we have a lot of code that just uses
ctx = new InitialContext();
when looking up EJBs, queues etc.
Actually, to take the problem one step further, it should be expected that later
we will have EJB's deployed on different machines/clusters - so we will actually
need specific urls for each EJB.
Is there a good way to do this? Or will we have to custom-develop our own jndi
configuration standard using application parameters to set which JNDI provider
each EJB should be looked up with?
Alternativaely, can we "import" the JNDI trees of the app server in the JNDI tree
of the web servers?
So, how should we go about this?

Hi Robert,
You are right. But The object "myVar" which I am trying to look upis not in
the JNDI tree nor am I interesed in binding it . But my requirementis that
I have one application specific variable which I am trying to lookup and I
dont want to have a separare config file for this..and hence the question..So, put the properties you want in the jndi.properties file and load
the properties
file from your code by doing something like this:
Properties props = new Properties();
ClassLoader cl = Thread.currentThread().getContextClassLoader();
if (cl == null)
cl = System.getSystemClassLoader();
InputStream is = cl.getResourceAsStream("jndi.properties");
props.load(is);
Personally, I would not use this file and would create an application-specific
file
or, as Daniel suggested, define your properties as a System property
and use
System.getProperty("myVar").
btw, is jndi.properties only for those objects which are bound to jnditree?
jndi.properties is only used for creating the JNDI InitialContext. The
whole idea
of this file is that in remote client code (without the jndi.properties
file), you
need to do something like this to tell the JNDI classes how to connect
to the JNDI
provider:
Properties props = new Properties();
props.put(Context.PROVIDER_URL, "t3://myservername:7001");
props.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
InitialContext ctx = new InitialContext(props);
but inside the server, you only need to do this because the server is
the provider
and already knows how to connect to itself:
InitialContext ctx = new InitialContext();
Therefore, the jndi.properties file allows you to externalize this property-setting
code that sets up the properties to be passed to the InitialContext constructor
so
that the remote client code can now look exactly like the code inside
the server.
The InitialContext constructor will look for this jndi.properties file
in your
classpath and load it to get the necessary configuration information
to determine
how to connect to the JNDI provider.
Hope this helps,

What needs to be in my jndi.properties file to get oracle accessed by a jndi client
I am trying to write a connection pool class that use jndi
to locate the data base. I use "bindds" bind my OracleDataSource
object with the name of 'test/jdbc/test'. I should then be able to do a lookup like: OracleDataSource ods =
(OracleDataSource) ctx.lookup (test/jdbc/test)
All Oracle code examples use (Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
Is this correct? And what other things should be in my jndi.properties file to access the naming service with comes with
Oracle (Jserver)? For example to I need to include a Context.PROVIDER_URL value. I would think Oracle would have some
standard way of accessing its own Naming service. Thanks DavidThis implies that ODP.NET does NOT need to be installed on a client. However, I cannot find OraOPs9.dll on a machine with Client Release 9.2 installed. Should OraOps?.dll automatically come with a Client installation of 9.2 or higher?
ODP.NET needs to be installed on the client. OraOps9.dll is part of ODP.NET, not the Oracle Client.
Also, if an application is built with the 10g ODP.NET, can it be run from a machine with OraOps9.dll?
If an application is built with 10g ODP.NET, it can be run with 9.2 ODP.NET as long as you do not use any 10g APIs. The new features in 10g ODP.NET are included in the doc and the ODP.NET FAQ for your reference. -
Hi I have installed the Logical Host of JCAPS .Also I can explore the different
MBeans of it using JConsole.
If I want to access those MBeans programmatically what would be the
JNDI properties ?
For examplke if I want to access JBoss 3.2.5 MBeans My sample code would be something like ....
InitialContext ctx = null;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
env.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
ctx = new InitialContext(env);
So what would be my INITIAL_CONTEXT_FACTORY,PROVIDER_URL,URL_PKG_PREFIXES etc
in this case ?
If somebody has any idea please reply . When I was working with JBoss 3.2.5, I got all the related information from JBoss Administration Guide .
Does JCAPS has any specific doc which can help me in this regard ?
Regards,
AyanI use the following properties to connect to the jndi tree.
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");

I don't see any of my jcd's when I walk this tree.
Can anyone tell me why? I'm expecting to see a list of jcds.
When I look into the sun-ejb-jar.xml file, I see that I should be able to lookup the deployed service with the following name;
ic.lookup("java:comp/env/ejb/local/stc/testHarness3Deployment1/deployedServices/CMap1_Collaboration_11")Are my assumptions correct, or is my jndi knowledge faulty? -
Servlet with Issues writing to MySQL Database using JNDI

As mentioned in the title, I'm using JNDI for connection pooling, via META-INF/context.xml.
I'm also using JDBC Realm with a form, and that's working just fine, so I'm sure my issue isn't context.xml, as it seems to be overriding Tomcat's context file just fine, at least for authentication.
Below is the code from the servlet, to include the annotations:
package projectEgress.web.blog;
import java.io.*;
import java.text.*;
import java.sql.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.*;
public final class blogInput {
/* bean properties */
private String blogHeader;
private String blogSubheader;
private String blogBody;
private String externalLinks;
Connection conn;
Statement stmt;
/* getters & setters */
public String getBlogHeader() {
return blogHeader;
public void setBlogHeader(String blogHeader) {
this.blogHeader = blogHeader;
public String getBlogSubheader() {
return blogSubheader;
public void setBlogSubheader(String blogSubheader) {
this.blogSubheader = blogSubheader;
public String getBlogBody() {
return blogBody;
public void setBlogBody(String blogBody) {
this.blogBody = blogBody;
public String getExternalLinks() {
return externalLinks;
public void setExternalLinks(String externalLinks) {
this.externalLinks = externalLinks;
/* like it says, a void which writes to the database */
public void writeToDatabase() {
/* create the query string to fill the table */
String query = "insert into blogEntry (blogHeader, blogSubheader, blogBody, externalLinks) values (\"" + this.blogHeader + "\", \"" + this.blogSubheader + "\", \"" + this.blogBody + "\", \"" + this.externalLinks + "\")";
try {
/*establish the datasource and make the connection */
Context ctxt = new InitialContext();
DataSource dsrc = (DataSource)ctxt.lookup("java:comp/env/jdbc/projectEgress");
conn = dsrc.getConnection();
stmt = conn.createStatement();
/* Add data to table 'blogEntry' in our database */
int input = stmt.executeUpdate(query);
/* close the connections */
stmt.close();
conn.close();
/* check for exceptions, ensure connections are closed */
} catch (SQLException sqlx) {
sqlx.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (stmt != null) {
try {
stmt.close();
} catch (SQLException sqlx) {}
if (conn != null) {
try {
conn.close();
} catch (SQLException sqlx) {}
Here are the settings I have in META-INF/context.xml (sans Realm stuff, which works):
<Context debug="1" reloadable="true">
<Resource name="jdbc/projectEgress"
auth="Container"
type="javax.sql.DataSource"
username="********"
password="********"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/projectEgress?autoReconnect=true"
validationQuery="select 1"
maxActive="15"
maxIdle="8"
removeAbandoned="true"
removeAbandonedTimeout="120" />
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<WatchedResource>META-INF/context.xml</WatchedResource>
</Context>And, finally, the code I'm using in the JSP which calls the method (the form action is directed to this file's URL):
<jsp:useBean id="blogInput" class="projectEgress.web.blog.blogInput">
<jsp:setProperty name="blogInput" property="*" />
<jsp:scriptlet>blogInput.writeToDatabase();</jsp:scriptlet>
</jsp:useBean>
-YES, I know I'm using a scriptlet in a JSP... I really don't want to create a custom tag to call the method, at least not until I'm far along enough in the project to justify creating a library... let's make it all work, first! :o)
FINALLY, the form:
<form action="/projectEgress/area51/blogInput" method="post" id="adminForm" enctype="application/x-www-form-urlencoded">
<div>
<span class="inputheader">Blog Header</span><br />
<input type="text" name="blogHeader" size="35" class="form" /><br />
<span class="inputheader">Blog SubHeader</span><br />
<input type="text" name="blogSubheader" size="45" class="form" /><br />
<span class="inputheader">Blog Body</span><br />
<textarea class="content" name="blogBody" rows="9" cols="60"></textarea><br />
<span class="inputheader">External Links</span><br />
<input type="text" name="externalLinks" size="45" class="form" /><br />
<input type="submit" value="Post!" class="submit" />
</div>
</form>As far as I can tell, it should work, and it doesn't throw any errors (in fact it shows the success message rather than the configured error page), but when I check the blogEntry table from the MySQL prompt, it responds with "Empty set".
I've double checked to ensure that the table columns are present in MySQL and all the naming conventions line up and they do, so I figure it's my servlet that's broken.
Advice? Ideas?
Thanks in advance.
Edited by: -Antonio on Apr 25, 2008 8:03 PM with additional infoOkay, I changed a few things in the servlet code.
For one, I'm trying a PreparedStatement in place of Statement. Don't ask me what made me think it would work any better, it just stores the sql query in cache, but I thought I'd just try something else.
One thing this is allowing me to do is make the connection and statement (now PreparedStatement pStmt) objects local variables. It wouldn't allow me to do so before without giving me compile errors.

public void setBlogHeader(String blogHeader) {
this.blogHeader = blogHeader;
public String getBlogSubheader() {
return blogSubheader;
public void setBlogSubheader(String blogSubheader) {
this.blogSubheader = blogSubheader;
public String getBlogBody() {
return blogBody;
public void setBlogBody(String blogBody) {
this.blogBody = blogBody;
public String getExternalLinks() {
return externalLinks;
public void setExternalLinks(String externalLinks) {
this.externalLinks = externalLinks;
/* like it says, a void which writes to the database */
public synchronized void writeToDatabase() {
Connection conn = null;
PreparedStatement pStmt = null;
/* create the query string to fill the table */
String Query = "INSERT INTO blogEntry (blogHeader, blogSubheader, blogBody, externalLinks) VALUES (\"" + this.blogHeader + "\", \"" + this.blogSubheader + "\", \"" + this.blogBody + "\", \"" + this.externalLinks + "\")";
try {
/*establish the datasource and make the connection */
Context ctxt = new InitialContext();
DataSource dsrc = (DataSource)ctxt.lookup("java:comp/env/jdbc/projectEgress");
conn = dsrc.getConnection();
pStmt = conn.prepareStatement(Query);
/* Add data to table 'blogEntry' in our database */
pStmt.executeUpdate();
pStmt.clearParameters();
/* close the connections */
pStmt.close();
conn.close();
/* check for exceptions, ensure connections are closed */
} catch (SQLException sqlx) {
sqlx.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (pStmt != null) {
try {
pStmt.close();
} catch (SQLException sqlx) {}
if (conn != null) {
try {
conn.close();
} catch (SQLException sqlx) {}
}Someone out there has to have a thought on this.
Even if it's just something they think probably won't work, so long as it gives me another angle to see this from.
