As you can see from the way that Struts itself uses the digester (for example,
when parsing struts-config.xml), you can see that the set properties rule is
quite common.  Would it be possible to run this in an environment with the JIT
turned off, so we can see what line number in SetPropertiesRule is throwing the
exception?  Also, could you post the logic you're using to initialize the
digester -- at least for the patterns that match when you get the exception?
(It might also be useful to call digester.setDebug(999) so you can see trace
output on System.out).

The most likely cause would be if there are no items on the object stack
(perhaps because you didn't call an object create rule on the same pattern
first), but the only way to know is to have a few more details.

If we have any XSLT gurus in our midst, this sounds like it is something that

The EJB analogue for this would be to add a finder method that implemented the

[scriptlets to execute JDBC inside a JSP]

>I'm working on adding metadata and other convenience methods now. I'll

>others might have found to handling JDBC queries within Struts.

The design I us works like this:
- for each logical item of data write a trivial class with all the
  get/set methods (the Entity class).
- for each such trivial data class write a likewise trivial class that
  does know how to map a ResultSet to the Entity class. Some SQL-Stmt
  merging code is added as well to tune the query (the Retriever class).
- for each logical query add a more or less trivial class that does the
  actual JDBC stuff (the Controller class).

For all of the above there exists base classes that make writing the
code very simple.

The Entity class can easily be exposed to Struts and used there.

Th Controller class is invoked from Action; if there is some initialization
to be done for a JSP create an action that's executed before the JSP is
actually displayed.


AFAICT the design outlined above does facilitate a better separation
between the underlying physical data model and the way this data is
represented to the user than can be achieved by using scriplets.

If anyone is interested I'd be willing to share the code (though I'd
have to check on copyright before).

Best,

Problem with Digester used "standalone"

[Martin Cooper]

I've been trying to use the Digester module on its own (i.e. no other Struts
code, no servlets, no JSP), and have been having problems. At first, I
thought it must be my application code, but then I tried copying the code
from the Struts example DatabaseServlet into my own Java application and
came across the same problem.

The problem happens when addSetProperties() is used. The call itself
succeeds, but later on, when Digester.parse() is called, I get the following
error and call stack:

java.lang.NullPointerException
at
org.apache.struts.digester.SetPropertiesRule.begin(SetPropertiesRule.java,
Compiled Code)
at org.apache.struts.digester.Digester.startElement(Digester.java,

at mfnc.TryDigester.TryDatabase(TryDigester.java:92)
at mfnc.TryDigester.main(TryDigester.java:18)
org.xml.sax.SAXException

If I comment out the calls to addSetProperties(), everything works just fine
(except that I don't have the property values I wanted :-) ).

Anyone have any ideas about what I might be doing wrong? I know this isn't
how the Digester is expected to be used, but, well, it just seemed like a
handy class for parsing simple XML files...

Thanks!

Submit tag fires when page first displays

I am using version 0.5 of Struts (release version)   I have a login form

Where would I look, read, etc to figure out how to make it only fire the

The Serializable implementation of MessageResources is in the current nightly
builds of Struts, and has been for at least a couple of weeks.

The Struts example application still has some non-Serializable context
attritutes, but as far as I know all of the components stored there by the
framework itself are now Serializable -- if I missed something, please report a
bug.

Ant provides a hierarchy of mechanisms by which properties can be defined.
Essentially, the following list is checked from top to bottom until an
appropriate definition is found:

* A command line setting (-Dservlet.jar=xx)
  passed to Ant

* A system property named "servlet.jar" passed to
  the JVM inside which Ant is running

* A  setting inside the build script itself.

In the case of Struts, the build script ("build.sh" or "build.bat") that you use
looks for an environment variable named SERVLETAPI_HOME, and uses that to
construct an appropriate value:

java ... -Dservlet.jar=$SERVLETAPI_HOME/lib/servlet.jar ...

See the comments at the top of build.sh or build.bat for more documentation on
the environment variables you can use to control where the build gets its files
from.  The Ant user's manual (which comes with the Ant distribution in file
"docs/index.html") is also very useful when trying to understand build.xml
files.

Re: Business Logic Beanies

[Ted Husted]

I'm finishing up on a model for executing JDBC retrievals from a JSP,
using a scriptlet like 

<% 
  FruitSalesForm fruitSalesForm = (FruitSalesForm)
session.getAttribute("fruitSalesForm");
  fruitSalesForm.setPageContext(pageContext); 
%>

to execute pooled JDBC connetions, and transfer the results into
page-scope collections,  for use by the iterate or option tags. 

To get there, I 

Setup straight "data beans" to represent the rows of a table (or a form
option). 

Subclassed a "QueryFormBean" from ActionFormBean to encapsulate the
query string, execute the query given a GenericConnection, and to track
the last relative position in the result set.

Subclassed QueryFormBean to return an array of data beans from the
object's ResultSet (a RowSet would be better). This array is ultimately
inserted directly into the page context, for use by an iterate or
option tag.

Subclassed a "ActionDataForm" from ActionForm, and added methods to
expose key JSP and Struts resources via the page context, and a method
for obtaining a GenericConnection from the servlet. 

Implemented the ActionDataForm with the subclassed QueryFormBean as a
property. Overrode setPageContext to execute the QueryFormBean, and
insert the databean array into the page context. 

I'm working on adding metadata and other convenience methods now. I'll
post the working example soon. Just wondering what similar solutions
others might have found to handling JDBC queries within Struts.

The ActionErrors.get("username") method will return you an Iterator of all the
error messages recorded against the "username" property -- there could be more
than one.  The  tag currently doesn't have any support for this,
and I'm not sure there is a good generic solution that works in every
circumstance, although I'm open to suggestion.

Problem w/ example using Websphere

[Marilyn Bratis/Towers Perrin]

Hi,

I'm trying to run the struts example under Websphere 3.5.2 but I keep
getting the following error:

Message: Server caught unhandled exception from servlet [JSP 1.1
Processor]: com.ibm.servlet.engine.webapp.UncaughtServletException: Server
caught unhandled exception from servlet [JSP 1.1 Processor]: Missing
resources attribute org.apache.struts.action.MESSAGE

I saw this error addressed under the Orion install documentation and I
tried applying the same fix but had no luck.  Has anyone else tried to
implement struts under Websphere?  I did successfully deploy the struts
example using JRUN, but I don't know what to try next for Websphere.

Thanks!

Re: Form errors

[Johan Compagner]

Use my ErrorTag attached.
I copied almost from ErrorsTag but only generated it for the property that was set.

I hope this or another one just like it will be in the default struts lib.
(they can use mine attached)

The current implementation isn't used very much on the internet. Users want
to see what the did wrong and where to fix it. 
And that's why the ErrorTag is much handier then the ErrorsTag.

If multiply errors are set for one property it will be comma seperated.

RE: SilverStream 3.7 and Struts

[Ludwig, Pat]

Bill,
the non-serializable nature of MessageResources is a likely cause for your
problem. even if your app doesn't use MessageResources, Struts itself does.
if this is the cause of your problem, cycling the Silverstream server should
resolve it.

There was some mention a while back in a thread titled "Proposed Solution to

MessageResources in my web application, but I am encountering the following
when deploying a very simple struts web app to SilverStream:

SilverStream support indicated that this had something to do with the way

Is there an update (Struts or SilverStream) that addresses this problem?

errors.add("username",new ActionError("error.username.required"));

Now, in my .jsp, rather than having all the errors displayed with
, I want to put the
error.username.required error right next to the username field:

  


I don't want it to use errors.header or errors.footer either in this case.

Is that possible?
Thanks.

How do you have your environment setup? Where did you put the Struts.jar and 
your application classes?

SilverStream 3.7 and Struts

[Bill Pfeiffer]

There was some mention a while back in a thread titled "Proposed Solution to
Non-Serializable MessageResources Class" that described a problem that I am
encountering with SilverStream 3.7.  I am not actually using
MessageResources in my web application, but I am encountering the following
when deploying a very simple struts web app to SilverStream:

java.lang.LinkageError: Class org/apache/struts/action/ActionForm violates
loader constraints

SilverStream support indicated that this had something to do with the way
the MessageResources is not serializable.

Is there an update (Struts or SilverStream) that addresses this problem?

TIA,

Bill Pfeiffer
