Hello,

I'm new to JSF. Could someone please point me in the right direction in how I may create a grid or table, which for a particular cell could have multiple items created dynamically, like buttons or links.
I see that there are tables, gridpanels and CSS Style sheets. If anyone could recommend a general approach, example or tutorial, it would be extremely helpful and greatly appreciated!

Thank you,

Ken

Hi Deepak,

"Meaning the variables do not appear under the "variables" view ? Is eclipse aware of the source files to the .class that you are debugging ?"

Eclipse is aware of my source and lets me step through it in debug mode.

The variables appear under the variable (expressions) view, but eclipse is indicating that a String like bio (shown below in code) cannot be resolved to a variable even though I executed the line.

I can see values for some variables like like 'this' and 'arg0'.

I built the code outside of Eclipse and imported the .war file into a project to debug.

Thanks,
Ken

Hello,

I'm trying to debug a simple servlet on Eclipse running under Tomcat. I can get the Servlet to run and stop at the breakpoints, ( can see code) but I can't
see any of the program variable values.
javascript:emoticon('');

Eclipse is Java EE IDE for Web Developers Build id: 20100917-0705. Tomcat is 6.0.30.

I started Tomcat with the following file as recommended by a tutorial:http://www.wikijava.org/wiki/Debugging_a_servlet_with_tomcat_and_Eclipse_tutorial

set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket
catalina.bat jpda start

The application is launched as http://localhost:8080/formexample/formServlet

The debug session is remote debug with connection type of standard socket attach and connection properties are localhost 8000.

If anyone can tell me why I can't see the variable values, I would be greatly appreciative!!

Thanks,
Ken

Hello,

I am setting up my Tomcat JNDI realm as:

<Realm className="org.apache.catalina.realm.JNDIRealm"
connectionURL="ldap://Au-dc1:389"
connectionName="CN=Ken Rubin,OU=Development,OU=Corporate,DC=mycompany,DC=com"
connectionPassword="mallory1"
userBase="OU=Development,OU=Corporate,DC=mycompany,DC=com"
userSearch="(sAMAccountName={0})"
userSubtree="true"
userRoleName="cn"
/>

I am only able to log onto Tomcat Manager if I set
userRoleName="cn", when as an attribute = "Ken Rubin". In web.xml for the Tomcat manager, I had to
set my name as a role. ie.

web.xml
<auth-constraint>
<role-name>Ken Rubin</role-name>
</auth-constraint>
</security-constraint>

<security-role>
<role-name>Ken Rubin</role-name>
</security-role>

My directory in LDAP is at "CN=Ken Rubin,OU=Development,OU=Corporate,DC=mycompany,DC=com".

I had wished to set userRoleName="memberOf" and return the roles for me, one these roles would be in my web.xml
instead of Ken Rubin. But I have been unable to do this.

One thing I noticed is that none of our company roles have any attributes listed under them.

Also I don't know how to get the logger to give me more possible information about why I am failing.

Any help would be greatly appreciated!

Thank you,
Ken

Hello,



Has anyone else had trouble starting Glass Fish in Netbeans 6.5.1? I got this when I initially tried to deploy HW for Webservices.



I get a message:

Authentication for GlassFish v2 failed with message Invalid user or password



It says that if the username or password is incorrect, you can change them via Tools|Servers. I have the admin user id and have tried to change the password many times, but still get the same message.



Any ideas?

Hello,

Can I call mysql_query() construct from a java program or something like it? (I want to use a LOAD INFILE ... from a text file to database and run it from java).

Thanks,

Thanks Ulf, now I know how to attack the problem.

Thank you for responding so quickly!

When I do the following command

C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap\classes>java -classpath "C:\ebay
JavaSDK\SDKInstallDir\externalLib\axis-1_1;C:\ebayJavaSDK\SDKInstallDir\lib" com
.ebay.migration.CallJsdk

I get the exception for the CallJsdk:
Exception in thread "main" java.lang.NoClassDefFoundError: com/ebay/migration/CallJsdk

Not sure why.

Hello,

Asking about this topic is a bit embarassing

I'm try to run an executable with the following conditions:

My top level directory is C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap

The source code is one file at C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap\com\ebay\migration\CallJsdk.java. It has a package of com.ebay.migration.

The class file is at C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap\classes\com\ebay\migration.

When I try to run the code at the C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap\classes> directory by typing

java com.ebay.migration.CallJsdk, I get Exception in thread "main" java.lang.NoClassDefFoundError: com/ebay/sdk/SdkException.

or

java -classpath "C:\ebayJavaSDK\SDKInstallDir\samples\JSDKToSoap\classes" com.ebay.migration.CallJsdk - I get the same thing.

Can someone please give some assistance? I should know this.

Thanks,

Ken

Thanks for the response.

It took me some time to realize that I had a redundant class directory hierarchy where I was putting my changes, which wasn't
under WEB-INF, so any changes I made did not take. It's ok now.

Thanks again,

Ken

</Context>

My classpath for the JDBC driver is:
C:\mysql-connector-java-5.0.7\mysql-connector-java-5.0.7-bin.jar

I can get data from the database using non Servlet programs.
Any insight would be greatly appreciated!

Thank you,

Ken
