Hi, I am using Struts 1.02 and got the following Problem:
I need to create a JSP where u can select to create a pdf or excel file.
The problem is, I didn't programm the Action to create the file, a
colleague did.
So I need some way to call his Servlet. I tried to map directly to it,
that did not
Hi Sandra.
For each column header you need a link that gives the required
parameters to your Action.
You can add 1 static and one dynamic parameter.
If you need more dynamic parameters, you need to add a map.
Without map:
html:link page=/sortmyRecords.do?staticparameterName=columName
I don't understand why you cannot directly use the PDF-generator servlet, by
adding a dedicated mapping in your web.xml.
It needs to go through the request processor, to check if the user is
logged in
or not.
perform() method in any action MAY return an ActionForward, but CAN return
null if
I never set content-length when generating response (PDF or not). Perhaps
you have a mistake in length calculation and browser waits for EOF ? Try
without.
Nope. I know it works as it works without Struts.

Because then I wouldnt have a request processor.
The rest of the application is written in struts and uses the request
processor to
check wether the user is logged in or not.
If not, he gets forwarded to the login page instead of creating a pdf.

Use logic present or logic equal tags.

Got a question about ActionClass and ActionForm.

what happens if there already exists an instance of the ActionForm I am
creating ?
Will a new instance get created, or will the existing instance get used
?
If the same instance will
Well,
I have to admit, the more I learn about Struts,

Of course I pass an instance of the ActionForm into my execute method,
but I am simple using ActionForm form
How to fill an Actionform after using an ActionClass ?
Normally a user fills out a form on a jsp, then the Actionform gets
called and filled by the data the user entered.
Then the ActionClass gets started and uses the data from the ActionForm.
But I've got an Action that creates data, and it
hmmm.
Tried it this way:
AlaskaGroupsForm alaskaGroupsForm = (AlaskaGroupsForm)form;
alaskaGroupsForm.setGid(gid);
alaskaGroupsForm.setBeschreibung(beschreibung);
alaskaGroupsForm.setStiwo(stiwo);
alaskaGroupsForm.setMo(mo);
alaskaGroupsForm.setStiwoerg(stiwoerg);
I want to add data records using a jsp.
When the user entered the data, and hits submit, an actions adds the
data record to the database.
When this is done, it forwards to the same page again, so that the user
can add more data records.
The problem is that the form gets filled by the ActionForm

Do I just need to repeat paramName=myForm

What's better:
To have a bean let's say BookBean.java

and an Actionform that uses this BookBean,

Imho it's much faster and easier to have your properties in your

Use the link page like the others told you.
Just in case your logoff Action needs a dynamic parameter (like userid)
you can do this like this:

Well, of course you can put your image into the link instead of text,

I have to admit so far I never used an image link,

I guess you got just the same problem as I had.
1. I guess you misunderstood the way of ActionClass and ActionForm.
First of all, the ActionForm gets filled with the data the user types in
the input fields on your jsp. Then the action gets called.
So I bet putting your List into a Form won't
Nope, it's in session scope.
Imho I know what happens:
the parameter is in session scope, but when reloading my jsp,
there comes the form again, and the parameter gets reset.
