Validating id and password against rdbms using struts1.1

hi
in our current project we r using struts1.1. in my action class i have to validate the login id and password against database, iam also using DAO pattern my DAO is a java bean.
so pls help me to validate loginid and password against database using DAO pattern.
thanks

Hi,
You can use OJB (http://db.apache.org/ojb/). We are using OJB with Structs and work perfectly, you can check it or look for other equivalents.
Of course, you can program your own DAO pattern, but I recommend you try this software.
Good luck,

And I implemented the following guide on oracle's website, but I faced with so much problem, please help me clearly on integration struts1 in weblogic portal, what's required? if can, please step by step.

Java Message Service (JMS) is a standard API for accessing enterprise messaging systems.
And WebLogic JMS is an enterprise-class messaging system that is tightly integrated into the WebLogic Server platform. It fully supports the JMS Specification.
Please refer to the following links to get more information on this and how to configure the jms resources:

Struts1 ear app is not invoked in weblogic10.3.4 same works in 10.3.0

Hi,
I have an exploded ear which is a a struts 1 application. I have deployed it on Weblogic 10.3.0. and same is deployed on Weblogic10.3.4 also.
Now when I try to invoke it on 10.3.4, I get "Error 404--Not Found", But the same can be invoked in 10.3.0 and I have made no changes in it.
I am using struts action as welcome page as :
<welcome-file-list>
<welcome-file>security/loginInit.do</welcome-file>
</welcome-file-list>
I think something is wrong with Weblogic 10.3.4 and struts1.
Please help.

Hi --
Thanks for the update, glad you have it working.
Just wanted to fill in some more information.
According to the Java EE 5 specification, if you have an empty context-root entry in application.xml the following applies:
>
Assign a context root for each web module included in the Java EE application. The context root is a relative name in the web namespace for the application. Each web module must be given a distinct and non- overlapping name for its context root. The web modules will be assigned a complete name in the namespace of the web server at deployment time. If there is only one web module in the Java EE application, the context root may be the empty string. If no deployment descriptor is included in the application package, the context root of the web module will be the name of the web module file relative to the root of the application package, with the .war extension removed. See the servlet specification for detailed requirements of context root naming.
>
So it should be possible to have <context-root></context-root> as you had.
I haven't tested it, but I presume if this is the case, then the actual context-root that is assigned will be the name of the web module war file, minus the .war extension. You have "Web" (no .war?) as the web-uri, so presumably the context-root for your application in this case would be "/Web".

That appears to be a bug in the console. You might try the command-line tool java weblogic.Deployer for deploying apps. java weblogic.Deployer -examples will give detailed usage info.

How to use ADF Faces with struts1.3.8

Hi
Can anybody guide us how to use ADF faces with Struts 1.3.8.
Your help will be appreciated.
Thanks
Chetan

Xpp,
Have a look at the ADF Developer's Guide for specific instructions on menus (the ADF Developer's Guide for Forms/4GL Developers has the information in section 19.2).
You can put javascript handlers on the components to get keyboard event handling.

Struts1.1 + tomcat 5.5 and jndi

Hi all,
I have made a web application using struts 1.1. In this I am using tomcat container security check for log in. For this I have REALM tag in META-INF/context.xml. Now I am thinking to use JNDI for connection pooling, so that I can avoid to put database userid and password in struts-config.xml (datasource). Before implementing jndi it was working perfectly and security check as well, but now it always decline to verify the login.
Here is my code for the the following files:
context.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/InformProject" docBase="InformProject">

Struts1.1(multi_app_modules) and JDev

Hi.
I am using JDev(903 & 10g) to develop a web app containing "multiple application modules" (a Struts 1.1 feature). However i met a problem to retrieve content from resource file defined in the struts-submodule-config.xml files. Here's the detail:
1> I defined two struts config files in the web.xml files, like
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>config/mod1</param-name>
<param-value>/WEB-INF/struts-config-mod1.xml</param-value>
</init-param>
2> All default module's jsp files were resided in /pages/ folder, and jsp files for mod1 were in /mod1/ folder.
3> I tried to switch from the default module to mod1 like this:
in /index.jsp page
<html:link forward="goToMod1">goToMod1</html:link>
in struts-config.xml file
<forward name="goToMod1" contextRelative="true" path="/mod1/index.do"/>
in struts-mod1-config.xml file
<action-mappings>
<action path="/index" forward="/index.jsp"/>
</action-mappings>
4> here's the content in /mod1/index.jsp
<bean:message key="index.heading"/>
<html:link forward="gotosomewhere">gotosomewhere</html:link>
in this page i tried to include a link to /mod1/somewhere.jsp and I defined also in struts-config-mod1.xml
<forward name="gotosomewhere" path="/somewhere.jsp" />
5> content in /mod1/somewhere.jsp
<bean:message key="msg" />
6> I created two resource files for both default and mod1 modules seperatly, defined them in the correct struts-config files and made sure that all required "key=value" paires are existed.
Now I run the program. I switched to /mod1/index.jsp file by clicking the "goToMod1" link from the /index.jsp page, and everything were correct so far.("index.heading" were retrieved from mod1's resource file correctly)
I clicked the "gotosomewhere" link in the /mod1/index.jsp page,and met the error page, said that [Missing message for key "msg"]. However, after i added a msg=abcdef in the resource file of the default module, it can work correctly, which proved that the /mod1/somewhere.jsp file incorrectly looked for "msg" in the default module's resource file, although /mod1/index.jsp file did the looking up correctly.
If i made something wrong, please help me to point it(them) out. thanks a lot.

When the application gets stuck - is there any error reported in the Weblogic log window?
In your IE - do you have XMLHttpRequest enabled?

Struts1.1b2 and websphere 4.00 problem !

Anyone here tried using the above two combination ?
I am getting this error
I SRVE0092I: [Servlet LOG]: Error Page Exception: : com.ibm.servlet.engine.webapp.WebAppErrorReport: Cannot find message resources under key org.apache.struts.action.MESSAGE
Any help would be appreciated.
Thanks

Struts is trying to find a property somewhere, and the key it's using to find it can't be found. Assuming you are using some sort of ApplicationResources properties file, it's probably just a typo.

Struts1.3 Application migration to webcenter

Hi,
I have struts 1.3 application, Tiles used running on weblogic Server . Now I need to migrate to Webcenter what is the best way I can do . So my plan is create Webcenter portal Application and create task flow ,portlet for exited code .Is that the right way or any sujjestion please If u have any sujestion or do im dooing wrong , do i need to recoding everything any sujestion

You have varius alternatives:
- Register your Struts + Tiles in WebCenter External Applications and you can execute your application without migrating code.
- Creating a Portlet to be consumed by WSRP protocol is the easiest way to migrate a struts applications.
- On the other hand you can build Custom Task Flow. Probably if you haven't good skills at ADF you can lost more time with this way.
You have the last decision.
PD: You have a Sample of register External Application in WebCenter (including SSO) in Andrejus Blog: http://andrejusb.blogspot.com/2011/03/automated-single-sign-on-through.html
Kind regards.

Hi,
Does anybody know where to find examples of using this jakarta dbcp in tomcat servlet?
I looked at http://jakarta.apache.org/commons/dbcp/ examples but they are all about run the Java class at command line. Where to config the tomcat with JDBC pooling?
Thanks in advance!

Got a problem with my Chatting-Room program, please help me if you can.

There is one bug in the code (should be just one), but I couldn't find it, I even recoded the whole thing, after I recoded the code, the same problem seems still there. I just can't find where the problem is. So I hope someone here can help me, thank you very much.
First, I made a Server and a Client. Server has 5 classes, and Client has 2 classes. My intention is that all the clients(running on other computers) will connect to the server (which is my laptop), and then they can communicate with each other. For example, if person A typed "Hello", person B and person C's computers will receive this message and display it.
The problem is that several clients can connect to the server (My laptop), but if one person type something, other people won't receive the message, it's blank on their screens. Maybe there is a problem when server receiving the message. So this is the problem I want to solve.
I have the code down there, here is a brife description what each class mainly does.
First class of Server is for connecting client, this class is named Server. Everytime a client is connected, the Server class calls the second class to store the client's information (which is its IP address), the second class is named People.
Third class is named Receiver, it is for receiving the massage from any one of the clients, then stores the message to a static field variable in Fourth class, fourth class is named Saying.
Fifth class of Server is named Sender, it is for sending the massage to the client, that message is the one that stored in Saying.
The First class of client is named Client, it prints any message that the server send to it.
The Second class of client is named SendFromClient, it wait for user to type something, and then send the message to the server, so server's Receiver class hopefully will get it and store it to the field variable in the Saying class.
Here is all the codes:
Server Class:

Hi pgeuens ,
I tried it ...but it didn't work for me.
I changed my .jsp like this
<%@ page language="java" %>
<%@ taglib uri="/tags/struts-html" prefix="html"%>
<html:form action="Registration.do">
UserName:<html:text property="username"/><br>
enter password:<htnl:password property="password1"/><br>
re-enter password:<html:password property="password2"/><br>
<html:submit value="Register"/>
</html:form>And i changed that web.xml like..
<taglib>
    <taglib-uri>/tags/struts-html</taglib-uri>
    <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>Now I am getting an error like ......."File "/WEB-INF/struts-html.tld"not found.
Hi Ashish
I didn't find struts-form.tld in WEB-INF folder.But all the remaining file all there.
Again I downloaded that struts1.2.9 ...in that also i couldn't find struts-form.tld file(except this remaining are there).
Please tell me, if there any other ways....
Thanks,
kona.

Log 4 j error in struts 1.2.8

I am using struts1.2.8 with hibernate 3.
I am getting below error.
Is there any solution for this problem ?
private DailyRollingFileAppender cAeroAppender;
     java.util.Calendar cal=java.util.Calendar.getInstance(); // getting calendar instance
                    logger = Logger.getLogger(cal.getTime()+"");
strLogLevel=CAeroConstants.getProperty(CAeroConstants.PROPTYPE_CONFIG,CAeroConstants.CONFIGPROP_LOG_LEVEL);
                         logger.setLevel(Level.DEBUG);
                    else if ( strLogLevel.equalsIgnoreCase("DEBUG") ) {
                         logger.setLevel(Level.DEBUG);
                    else if ( strLogLevel.equalsIgnoreCase("ERROR") ) {
                         logger.setLevel(Level.ERROR);
                    cAeroAppender = new DailyRollingFileAppender(new SimpleLayout(),strLogPath+".log","'_'MM-dd-yyyy");
                    logger.addAppender(cAeroAppender);

s).
06/04/18 20:50:01 log4j:WARN Please initialize the log4j system properly.
Raghu

It's not an error; it is merely a warning saying that the system is unable to find any log4j configuration. Create a log4j.properties and add it to the server classpath.
