based on my previous message I want to have multiple-selects named off
of a hashmap.
I have found and read all the documentation of "Mapped Properties" I
could find under Google.
I know my form bean is 100% correct based on the documentation, so that
is a not a worry there.
I have a:
HashMap mapValues = null;
setMapValues(HashMap mapValues);     returns HashMap with getMapValues()
setMapValue(String key, Object value)   and finally  
getMapValue(String key)

I created the HashMap in my preActionClass:
HashMap testMap = new HashMap();
testMap.put("a","value of a");
testMap.put("b","value of b");
testMap.put("c","value of c");

I tested this out in the jsp by using: <bean:write name="myFormBean"
property="getMapValue(b)" />
This does return "value of b" correctly.
I can even use a logic:iterate to loop through these three items and get
their key and values correctly!!!

Ultimately, I want three selects:
<select name="mapValues(a)"></select>
<select name="mapValues(b)"></select>
<select name="mapValues(b)"></select>

So ... now I created manually three selects on my jsp page.
<html:select name="myFormBean" property="mapValue(a)" value="not sure
yet"></html:select>
<html:select name="myFormBean" property="mapValue(b)" value="not sure
yet"></html:select>
<html:select name="myFormBean" property="mapValue(c)" value="not sure
yet"></html:select>

I just wanted to see if I could get my HashMap back to the post Action
and it constantly comes back null.

Can anyone help me deal with mapped properties, I am just not having any
luck and I've spent way too much time on this already.

Thanks!

I don't think Struts 1 will create the HashMap for you; you need to
instantiate it yourself (in your form bean's constructor or reset
method, for example). Assuming the map has already been instantiated,
Struts should be able to store form inputs into it OK.

What I was doing was instantiating the HashMap in the preAction class so
the logic:iterate worked on the JSP page.
But the information wasn't passing to the post Action class.  

Thanks for the information again. That kind of information I couldn't
find anywhere.  I will try it out ....
BTW ... I'm still trying to create:
<html:select name="myFormBean" property="mapValue(a)" value="not sure
yet"></html:select>
<html:select name="myFormBean" property="mapValue(b)" value="not sure
yet"></html:select>
<html:select name="myFormBean" property="mapValue(c)" value="not sure
yet"></html:select>
When I loop through the HashMap ... for some reason anything in the
property quotes is taken for a literal.
I can't seem to make it work with some form of variable.

Thanks again.

No shooting down, just a reminder that this is what the "css_xhtml" theme
attempts to do, sometimes successfully.

The action has to get strings out of the request, work out which file they are
from and call the appropriate managers, with the corresponding string as a
request. There's logic in the action that basically has nothing to do with how
the container handles it (I hope).

Didn't see that. I might use it. But I don't actually know quite what the
MultipartRequestHandler does, so I'm not sure how to mock it :)

I figured the ServletUnit framework would teach me.

You're saying it's reading the file and deciding what to do based on file
contents?

Well, either way, I'd still test that completely separately from any
container/request stuff, but without your understanding of how it's working
I'm mostly just babbling ;)

I see the multipart http request as a weak point in the servlet spec. Or the
http spec. But I want to test it for my own piece of mind, and when I have the
test finished, I guess I can work out if it's really necessary.

You want to test multipart HTTP requests? Well, okay; enjoy!

Dave

Just remembered struts2 isn't a servlet. I just wanted a quick and easy way of
giving my action a real multipart request wrapper to run against. So tomorrow I
guess I'll have to check out the MockMultipartRequestWrapper.

Hello,

I am writing an application using Struts (2.0.11), Spring (2.5.1), and
Hibernate (3.2.6), running on Tomcat (6.0.13). We have a legacy webapp
running on Tomcat that outputs some important information to the default
Tomcat logs. We aren't really in a position to change that application, so
we're trying to update our new webapp to put all messages in a different log
file. I'm trying to do this using log4j (1.2.15).

So far, I can add messages to the new log in my java code. I am also
getting freemarker.cache debug messages in the new log. However, all other
messages are still being put in the default Tomcat logs. For example, if
the database I'm trying to access closes its connection and I don't catch
the exception that is thrown, it gets printed to the screen, and put in the
catalina log. I would like that exception to go in the new log file instead
(and yes, eventually I will catch the exception and have struts display a
nicer error message for the user).

Below are the relevant parts of my web.xml, and my log4j.properties file.
Any help would be greatly appreciated!

Thanks!

Kelly

Your action mapping has class="mainpage", but your Spring configuration
has id="mainpageAction". These should be the same. I'm not quite sure
how you're getting the error you are, though, based on that
configuration. And I don't see how introducing an @Result annotation
would effect it. I suspect you have some out-of-date config files
deployed or something, since the error is inconsistent with what you
show here.

Try doing a clean build/deploy and check that the deployed configuration
is what you think it is. One other point to check: do you have the
struts2-spring plugin deployed? You need that to allow your actions to
be managed by Spring.

That's somewhat nebulous.

It would be more helpful if you could describe what specific issues you're
having or what you're trying to accomplish.

Hi all,

I've configured a data source at struts-config.xml. This data source use oracle thin jdbc driver. And I've already included the ojdbc.jar. Also, the oracle database I'm trying to connect is OK.

What version of struts?
Data-source got deprecated at some point. I forget the version.

Please Chen, the next time you post a question, say that you are using
Struts 1.1 *always*.
See the answers below.

I think this is the problem: specify a value for "minCount" and "maxCount".
And remember to close the connection once you used it!
Notice that, for default, a commons-dbcp datasource will be used,
while I suggest to use the Oracle datasource.
And, BTW, as Vinny said, the datasource support in Struts is
deprecated, I suggest you to use JNDI and configure the datasource in
your container.

Thanks.

I've tried to specify minCount=2 and maxCount=4. But I've encountered a new exception: The Network Adapter could not establish the connection. Is that mean something wrong with my network connection?

I'm using Struts 1.1

Here's the whole stacktrace. Note: the language version of my Tomcat 5.5 is Chinese. So I replaced some non-English text with translated English.

Can I see the complete stacktrace?

Antonio

Thanks Antonio

Now I can make it connected.

By the way, can I say that, if I use <data-source> in my struts application, then the struts servlet manages the connection? That is, when the application is deployed, the struts servlet will automaticly create connections of numbers specified by "minCount". And the application just fetch the connection created to use?

It seems that you cannot reach the Oracle server... can you ping it? Are you
able to see it through a sql client?

It's not Struts source, it's XWork source.

2.x != 2.0.11.1

http://struts.apache.org/2.0.11.1/struts2-core/dependencies.html

The appropriate version is available from either the XWork site, the XWork
repo in the /tags directory, or a source build of S2 under
/core/target/xwork-sources. (I don't recall if you have to do the build to
get this there or not.)
