Serious Struts Compatibility issue

[Yogaraj Khanal]

Hi All,
I have been working with struts for quite a while but facing various versioning issues.
I used Struts 1.3.8 and 2.0.6 and with Tomcat.I have some applications built on Tomcat 4.X and Resin WServer and Struts 1.2.7.
I have hard time solving error like Cookie.Tie,JasperException due to deprecited methods.
I have been installing and uninstalling Tomcat for hunderd times and switching between 4,5,and 6 to solve the compatibility issues.Since the application running in one doesn't run after some time.I am able to run so many tutorials in one config and again the same doesn't work.I am replacing jars with the latest and the earliest versions of Struts too.
Is there any platform that works for all???
Anyone Struts experts can guide me how to resolve this issue

All Struts 1 versions should run on all versions of Tomcat. However, Struts 2 requires a J2EE 1.4 compatible container, and only Tomcat 5 and above meet that requirement.

I'd have to know a lot more about your applications than I do to advise you on what might be going wrong. I will say, though, that if you're putting Struts jars in Tomcat shared directories, that could be causing the problems. Each Struts application should contain all Struts related jar files in its own WEB-INF/lib directory.

Are you using Netbeans. NB has good handling features

hi Yogaraj,

Failed to load or instantiate TagExtraInfo class
orgapachestrutstaglibbeanCookieTie
Please suggest me what do I need to do to resolve it

When do you get this error, and which container are you using.

And please post the original errormessage (by copy/paste) and don't retype it yourself.

One of the things we find time and again causing problems when applications are upgraded to later versions of struts is not being thorough enough in removing old artifacts and replacing them with new ones. You may want to go through this list of things and see if you've done them all:

remove all struts-related jar files from your application and replace them with new ones that came from the download of Struts that you will be using. This includes Apache Commons Jar files

Replace DTD references in all xml files with a reference to the new DTD. Then make sure that the XML files themselves conform to the new DTD

In the case of migrating from any 1.2.x version to any 1.3.x version, change all URIs used in <%@ taglib> tags to the newer style that uses a namespace instead of an actual TLD file location. You can see examples of the URI required in any of the JSPs in the struts-examples-1.3.x.war file that comes with the download

This is the erroe I am getting with jdk 1.4 Tomcat 5.0 and Struts 1.2.7

I am able to run a struts application using Resin,Struts 1.3.8 and jdk 1.4.
I am migrating same applicaiton in same platform to tomcat 5.0 the index page opens all the other jsp pages are working.But as soon as click submit button I have no idea why this error is coming anyone got any clue
I checked in jar and there I can see both ActionError and ActionErrors Classes in the jar.I don't know what to do next?
The error is like this java.lang.NoClassDefFoundError: org/apache/struts/action/ActionError

ActionError is deprecated in Struts 1.3. The solution is to remove all references to it and replace them with ActionMessage.

But I didn't make use of that class ActionError anywhere in my code.

But I can see both classes in the jar Both ActionError and ActionErrors.
Shall i unzip the jar delete those classes zip and put it back?

According to the stack trace you did. The stack trace indicates that at line 29 in a class named ActionBean, you made a reference to ActionError. If this line does not reference ActionError directly, perhaps it references another class that has a dependency on ActionError, such as a subclass of ActionError.

I got your point but how do I find how are the ActionError and ActionMessage related and how do I repalce the deprecated methods in ActionError since I am not using any of those.I am sending you both my ActionBean and ActionFormBean code.
import javax.servlet.*;
import java.util.*;
import javax.servlet.http.*;

import org.apache.struts.action.*;

public class ActionFormBean extends ActionForm
{
private String uname,pword;

public void setUname(String uname)
{
this.uname=uname;
}
public String getUname()
{
return uname;
}

public void setPword(String pword)
{
this.pword=pword;
}
public String getPword()
{
return pword;
}






}



import org.apache.struts.action.*;
import org.apache.commons.beanutils.PropertyUtils;

import javax.servlet.*;
import java.io.*;
import javax.servlet.http.*;

public class ActionBean extends Action
{
public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest req,HttpServletResponse res)throws Exception
{
String uname=(String)PropertyUtils.getSimpleProperty(form,"uname");
String pword=(String)PropertyUtils.getSimpleProperty(form,"pword");


if(uname.equals("gates")&&pword.equals("tech"))
{

return (mapping.findForward("success"));
}
else
{


return (mapping.findForward("fail"));
}
}
}

[Yogaraj Khanal]

Also I don't have any ActionError Class in my org.apache.struts.action package inside
struts-core-1.3.8.jar

I have only ActionErrors class I don't think this is what I want to make it work.

[Merrill Higginson]

This is very strange. Is there a possibility that the compiled class file for ActionBean does not match the source? Try deleting all class files and recompiling the entire project, making sure that your compile-time classpath contains only Struts 1.3.8 jar files.
