enctype set to multipart/form-data loses session

[Miriam Aguirre]

 Hi All, 

 I've come across a struts oddity.. in an struts form designed to upload a
file, i set the enctype="multipart/form-data". When a user does not use
cookies iplanet tacks on two parameters to all requests to keep track of the
session info. Like so (in the resulting html) :

 


 However, for some reason, when the request reaches the action, the session
is new (and therefore not authenticated). This is not happening with any of
our countless other struts forms.. only this one. Has anyone come across
this ?

 We are using struts 1.0.2 and iPlanet Application Server 6.5. Is there a
work-around ?


 Thanks!
 -Miriam

Subject: struts vs. JSP/Servlets


I want to use JSP and Servlets. Nothing else. 
What exactly does struts do for me that I can't do with Tomcat alone? 

I often hear struts/JSP. I also hear that struts allows us to build
applications in model 2 MVC form. But I also hear that about JSP and
Servlets. So then I started to think that struts is the framework that
allows us to use JSP/Servlet technology. But that must be wrong because I
installed Tomcat and it's running JSP/Servlets fine without installing
struts. So my question is still the one posed above. What does struts do for
me that I can't do with Tomcat alone (in the world of JSP/Servlets)?

RE: [OT] intermittent build and deploy Struts application to WLS problem

[Miriam Aguirre]

 iplanet has a whole slew of its own inadequacies.. for example, we can't
even get struts 1.1 to run unless we add the jar to its classpath (which is
not an option for us) - the class loader says it can't find the
PropertyMessageResourcesFactory even though its under the WEB-INF/lib
directory, so we're stuck with the older version of struts. Deployment is a
pain with iplanet, the deployment tool is really picky and inconsistent with
the command line deploy tool (which we prefer to use with ant, to make
'deploy' another target in the build file), sometimes it reports no errors,
but it doesn't deploy anything! To summarize, Iplanet sucks ( app server 6.0
SP4 and 6.5, still waiting for 7.0 enterprise edition).

I wondered if your post meant that you had similar problems with
build/deploy giving funny intermittent errors or if you were just fed up
with pricey app servers giving you headaches? 

For me changing app servers is not an option, but I would be fascinated to
know if you were having similar build/deploy intermittent errors - since you
apparently use iPlanet and I use WLS, that would lead me to think my problem
lies more with the ant/javac/jar tools or EAR structure than it does with
the WLS app server.  I really don't think it is the WLS app server, because
when an EAR file works it will continue to work over many deployments, and
when an EAR file fails it will always fail the same way over many deployment
attempts.

Did you really mean to say  name="foos" property="params.2"?  I tried it and

RE: html:link and array

 are you trying to create html links for all items in foos ? if so, you'll
need
  tags surrounding your html:link tags.
 And i think you mean name="foos" property="params.2"

It seemed to be related to something in this area of code:

// ModuleConfig config = (ModuleConfig)

// .getAttribute(org.apache.struts.Globals.MODULE_KEY);
//  try {

Hi All,

 while(enum.hasMoreElements())

  String att = (String)enum.nextElement();
 session.removeAttribute( att );
   }
 session.invalidate();

Subject: how to invoke the action servlet?



I have been referencing the book Struts in Action by Ted Husted as well as
the struts site. I cannot figure out what to point my browser to in order to
invoke struts. I have zero JSPs in my struts application -- I have no need
for them because I am utilizing Model X where I have one XSLT servlet that
represents my entire view layer. I thought I could just point my browser to
http://localhost:8080/ginsu (ginsu being the name of my web app). I realize
I have no index.html or index.jsp, but I'm just trying to go directly to the
action servlet from the browser. 

Is this not possible in struts? 


Here is my struts-config file: 


 
 
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";> 
 
 
 

 
 

 

 
 
 
 
 
 

 
 
 
 

 
 
 
 
 
 
 
 
 




And here is my web.xml file: 


 

http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";> 

 
 
 
action 
org.apache.struts.action.ActionServlet

/tags/struts-nested 
/WEB-INF/struts-nested.tld 
 

 
/tags/struts-tiles 
/WEB-INF/struts-logic.tld 
 

 
 


I noticed that there is an element: 


 
index.jsp 
 


Is this an absolutely necessary element in the web.xml file? I figure the
index.jsp would just contain a redirect to the action servlet. 


Any help is appreciated. Thanks!

last item in iterate loop

[Miriam Aguirre]

 Hi hi,

 Quick question, (I hope this is easy), is there any way to easily find
out if the current item in a  loop is the last item ?

RE: How do I pass value

[Miriam Aguirre]

 I'm sure there's many ways to do it, my (lazy) way of doing is to simply
append the parameter to forward name, such as:

 return new ActionForward(actionMapping.findForward(Success).getPath()
+"?parameterName="+ someName;

Subject: How do I pass value


I am new to struts and currently trying to test the following scenario.

After submitting a form, a image has to be displayed to the user. The image
is dynamically generated.The image file name is generated by the business
tier.As a part of the submission process, I have an action bean , action and
business logic class. I also have a forward for success.

  

  





In other words after the image.jsp is processed, I want to invoke the
showimage.jsp. This jsp file displays the image using .

The problem I have is how do I pass the filename generated by the
business(model) tier
to showimage.jsp.

Any help will be appreciated.

Thanks in advance

RE: BeanUtils.populate exception

 unfortunately, that's the only exception in the log :
 i;m going to try to change all the field/method names to all capitals.. not
sure
 if that will help, but i guess it can't hurt to try.

Do you know what the root exception is? It's usually included in the stack
trace of the servlet exception (called nested exception or something like
that). I think that would give a hint at what's really wrong.

RE: BeanUtils.populate exception

[Miriam Aguirre]

 
 ok.. since i haven't gotten anywhere in the past 3 hours, i'll repost
this..
 (i even looked through the source code, RequestUtils.java:774 is a throw
exception,
 ha ha).

 anyway, to further clarify my exasperation i have the following in a jsp:

   
   TRNG
     
   MB30


 which is rendered as follows :

     
   TRNG
     
   MB30


 and in the form bean i have :
 
  public boolean getTrng() {
if(getRecord() != null) {
if(getRecord().getMedsAccessInfo().getTrng().intValue() ==
Constants.TRUE)
return true;
}
return false;
}

public boolean getMb30() {
if(getRecord() != null) {
if(getRecord().getMedsAccessInfo().getMb30().intValue() ==
Constants.TRUE)
return true;
}
return false;
}

public void setTrng(boolean _trng) {
getRecord().getMedsAccessInfo().setTrng(new
Integer(Constants.TRUE));
}

public void setMb30(boolean _mb30) {
getRecord().getMedsAccessInfo().setMb30(new
Integer(Constants.TRUE));
}


 when displaying the page with a record, all the getters work fine.
 if trng is checked, and the form is submitted, it works.
 if trng is checked, and any other box(es) is/are checked, and the form is
submitted, it works.
 if trng is unchecked, and the form is submitted, it does not work.

 i'm not sure what the BeanUtils is complaining about.. i searched through
the archives, and it looks like these bean util exceptions occur with
indexed properties, but in my case, they're not indexed. does anyone see the
problem here?

 thanks,
 -Miriam

 I'm having a weird problem with a form ---
   the form has some basic html:text, html:select and html:checkbox ,
   fields are available to the user depending on the level of access they
have.
   the weird part happens with a  bunch of checkbox fields, for some users,
they all work great,
   for other users, if i unselect a specific box i get :

 this is really bizzare, because if all the boxes are checked, it works
fine. so it isn't some Action form/ jsp field naming discrepancy...

 anyone have any ideas ? or seen anything like it?

 i'm using struts-1.0.2 with iplanet 6.0 sp 4 on both win2000 and solaris

 thanks.

bean define problems

[Miriam Aguirre]

 Ok, after spending over a day on what seems to be a trivial task, I finally
have to ask!
 bean define is not "defining" variables in the page scope the way i thought
it should

 i have this in my jsp :

 

then somewhere further along :

 <%=fooBar.getColumnDisplayName(columnName)%>

 I get this error :
 [14/Mar/2002 11:27:24:5] error: Exception: SERVLET-compile_failed: Failed
in compiling template: /NASApp/webapp/reportTemplate.jsp, javac error:
c:\iplanet\ias6\ias\APPS\modules\webapp\WEB-INF\compiled_jsp\jsp\APPS\webapp
\reportTemplate.java:480: Undefined variable or class name: fooBar
  out.print(fooBar.getColumnDisplayName(columnName));

 
 ReportActionForm is the type of ActionForm i use for the jsp :



 
  


 
 I also tried adding 'toScope="page"' and that seems to make struts barf
[basically the java file is never completely generated from the jsp]:

2002-03-14 11:49:29 - ERROR-the file '\reportTemplate.jsp' generated the
following general exception: java.lang.NullPointerException
[14/Mar/2002 11:49:30:5] error: Exception: SERVLET-compile_failed: Failed in

 by the way, i'm using iplanet & struts 1.0.2 . What the hell is my
problem??

 Thanks.
