Re: microsoft sqlserver driver & struts

[Claire Wall]

ok i've manager to connect to the datasource! What I did was to move my jars
into common/lib.

Now I have another problem though. For some reason this driver does not like
my queries - more specifically it does not like table names used on their
own but only likes them when the database name and database user is inserted
before it like 'dbname.dbo.user_table'. Why is this? I cannot change all my
queries (and there are alot of them) so that they have this prefix as it
will cause many problems if the application has to be ported to another
database. Is this an SQL Server database setting, or something to do with
the driver itself?

I know I'm getting off the struts issue now but any help would be great! :)

Re: microsoft sqlserver driver & struts

[Claire Wall]

Ian,

This is the way I tried first as it seemed most logical to use the
SQLServerDataSource type from the mssqlserver.jar but this doesnt work for
me. The only one that made some progress was the
com.microsoft.jdbcx.base.BaseDataSource but then this threw some strange
error which said:

java.lang.NoClassDefFoundError: com/merant/jdbcspy/SpyLogger
 at com.microsoft.jdbcx.base.BaseDataSource.setLogWriter(Unknown Source)

I've had a look into this but I don't see why this error should be occuring.
Maybe there's something wrong I have done with where I've put the jars.. I
have three jars: mssqlserver.jar, msbase.jar and msutil.jar. the last two
look to be pretty similiar with regards to what they contain. I was
wondering whether this could be causing conflicts or something.

As I said, i can connect fine to the datasource from a test class but going
via struts is causing this Invalid DataSource problem.

Re: microsoft sqlserver driver & struts

[Claire Wall]

Mark,

My problem is that I'm switching JDBC drivers - before I was using
weblogic's JDBC driver for SQL Server and I've been using that for a long
time now and never had any problems. Now I'm trying to ditch the weblogic
driver and in its place use Microsoft's JDBC driver for SQLServer. Sorry,
should've mentioned that before. I'm not sure that showing the code for
getting the datasource is going to help because I'm assuming that this is
not the problem - the problem is surely to do with the type of datasource.

I had a similiarish problem trying to use an Oracle database - in the end
the type of datasource was the problem and not how I retrieved it in my
actions.

Have you used Microsoft's SQL Server 2000 JDBC driver with struts before,
and if so, what type of datasource do we use? Can't find anywhere that says
anything about it. Cant be too difficult..

Thanks
Claire

Re: microsoft sqlserver driver & struts

[Claire Wall]

It gets thrown when the application starts, but then more errors occur as
there are several servlets which load upon start-up - the data source is
null at this point (NullPointerException's are being thrown) and so the
errors are thrown when these classes try to access the database.

microsoft sqlserver driver & struts

[Claire Wall]

Hi,

I am trying to use microsoft's jdbc driver with my struts application, but to no 
avail. Here is my datasource definition:

  
   
   
   
   
   
   
   
   
   
   
   
  

I have the required jars located in the WEB-INF/lib of my application which is running 
on Tomcat 4.1.29. When i try to connect to the database using this driver from a test 
class, it connects no problem so i know that the url and driver class name are 
correct. So the problem must be the type of DataSource which I am to use. Does anybody 
know which datasource to use with Microsoft's sqlserver driver? I tried using the 
DataSource that is in the mssqlserver jar but this didnt work either.

The error that I get is an Invalid DataSource.

Any help would be really appreciated!

Thanks
Claire

if you use the nested tags rather than the logic and html tags then this

Re: Basic question on /lib/*.jar files

[Claire Wall]

we store them in the common/lib folder. Then all applications running on
that web server have access to the jars and negates the need for them to go
into the separate WEB-INF/lib folders for each application.

cw :)

Re: Tomcat error

[Claire Wall]

Just thought i'd add that this error might be something completey different

just i saw the error and put 2 and 2 together..

I'm guessing that this is because there are some non-serialized objects trying to be 
persisted in the session but its not allowing it because these objects are non 
serializable. Of course i could be completely wrong, which i probably am :-Þ

Anybody have an idea what this error could be? It's causing problems because the 
exception tomcat is throwing is saying that there is a LifeCycle exception and that 
the path '/ApplicationName' has already been started, even though it clearly is not 
running.

Re: Making the fields non editable dynamically using a form bean element

[Claire Wall]

Anant,

You can do the following:

set up a boolean flag at the top of the jsp page that will be used to
disable fields on your page like so:

<% boolean flag = false; %>

and then set this according to the value of the flag in your form using
logic tags:


<% flag = true; %>



<% flag = false; %>


and then in your  elements do this:




you have to make sure though that the boolean is set to the right value (so
that if you wish to disable something it is true - this got me caught out a
few times!)

Hi ppl,


I have a situation where I do not want the user to edit the fields if
the history record flag in the form bean is true.
Can you suggest me how to go about it. Can I use a form bean element
(java.lang.Boolean/String) to disable a  dynamically

If yes then how can I do it?

Re: html:options and html:select

[Claire Wall]

you can do the following:



">




'property' of the select box should be the name of the property in your
FormBean that you wish to store the selected value in.
You then iterate through the list in your form by using the 
tag. For every object in your list an  tag is written, where the
value is the property 'id' of the current CProduct and the name displayed in
the select box is the name of this CProduc object. This may not work as it
stands due to using an Integer object - i'm not certain that you can set the
value of a select box option to an Integer object. You'd have to try it and
see, and perhaps somebody can clarify this further, but I've never tried
this myself.

Re: Getting the CheckBox Collection Value in FormBean Class

[Claire Wall]

What is 'allreqcand'? I'm assuming that this is the name of your form bean.

When the form is submitted, whatever is the value of the check box will be
stored in the array (and only the checked ones will be submitted). So in the
example you gave, the values that will be stored in the array will be the
string 'check', which isnt very helpful. You should be able to determine
which boxes were checked by iterating through the array in your action like
so:

for(int i = 0; i < myform.getDeletereqs().length; i++)
{
//log the values of the checkboxes so you can see if its working.
}

the most important thing first is to check that something is being submitted
to the array when boxes are selected. If you log the values to the log file
by looping through the array in your action then you can see what's going
on. The next step is to get something useful to be submitted to the array
(values of the checkboxes).

Re: Getting the CheckBox Collection Value in FormBean Class

[Claire Wall]

Do you mean that you want to store checkbox values in a form bean? if so...


You can set up an empty String array in your form bean like this:
String[] checkboxes = new String[]{};


and then in your jsp page you can set the property of a checkbox to this
array, like:




when the page is submitted, the checked box values are stored in the array -
you can then use them how you wish in your action. Note though that you have
to set the value of the checkbox if you are going to have anything submitted
to the array in the form.

Re: How do you submit a page and not change values

[Claire Wall]

you can use the  and  buttons from within a form.
They will both actually submit the form to an action, but it is possible to
capture the 'cancel' event in your action and therefore forward the user to
different places depending upon which one they clicked on.

so, for example, say you had a form with one field called 'name' and two
buttons- one 'cancel' and one 'submit'...





Submit
Cancel



in struts-config you define your actions and where you wish to forward to
depending on which button the user clicked on:

  
   

  


and, finally, in your action you can catch the cancel event and forward to
the other place like so:

if(isCancelled(request))
{
return mapping.findForward("cancel");
}

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



I hope that this answers your question - if not then sorry if i am just
repeating stuff that you already know! :)

regards,
Claire :)

Re: Using "bean:write" as a tag's value atrribute

[Claire Wall]

This is fine as long as the tag you're using the  is not
another custom tag e.g.  or  etc. It is done like
this:

" /> - make sure you include '/' at the end of the bean
tag.


If you want to use this in a custom tag you're going to have to define a
bean first and then use a jsp expression so you can set the value like so:

Assuming that your Bean class contains simple data types you can do the
following:





So, for example, if you had a Bean with two fields, 'name' and 'phone' in
it, your form was called 'PeopleForm' in struts-config and your vector of
bean objects was called 'people', you could output the bean details to the
screen for each bean in the vector list like so:







hope this helps.

Re: problem with nested tags

[Claire Wall]

You cannot have custom tags within custom tags. As you say you want a
 tag within an  tag, then this will not work as
they are both custom tags. You could get around this by using 
and then using the value of this in your html:button tag like so:





or indeed you could do something like this:

 if you want to use the
 for the name of the button.

I'm not certain as to how you are trying to use  in your
 tag as I dont see an example of it in your code, unless I'm
being completely dopey... :)

Re: weird Tomcat prob

[Claire Wall]

i've just this minute fixed the problem - the servlet mapping for servlets
(/servlet/) was commented out in the web.xml file in the Tomcat conf folder
for some reason - this must be what it is like when Tomcat is first
installed - knew it would be something small and annoying.

cheers :)

weird Tomcat prob

[Claire Wall]

Hi,

I have a struts application which i am deploying to another server which is running 
Tomcat 4.1.29 via a WAR file. The application works fine except for one problem:

I have a servlet which loads on start-up via the following declaration in web.xml:

  
hasAttachments
HasAttachmentsServlet
5
  


It loads up fine - the servlet is found as it is logging to the log file that it is 
loaded. However, when I try to access this servlet it does not find the servlet at 
all. The servlet has a doGet() method which just passes back some text to be 
outputted. I call it like this: http://localhost:8080/CRM/servlet/hasAttachments. I 
get the following error message:


org.apache.jasper.JasperException: Exception reading resource 
http://localhost:8080/CRM/servlet/hasAttachments;jsessionid=B0636FAB02DF85F4E4980AF8092618AF?context=12&upload=false:

Re: Tomcat error with compiling JSPs

[Claire Wall]

we are using 4.1.24 and are pretty certain that what you say is exactly what
is happening. The path that the app was installed in was quite long + then
there's the package names on top of that and they are pretty lengthy too -
up to 7 folders in depth.

Thanks for your help!

I'm going to try it out at home where I have 4.1.29 installed and see if
this solves the problem, but I'm fairly sure that you're spot on.

:)

Subject: RE: Tomcat error with compiling JSPs


This is a known problem in some versions of Tomcat, due to a known
problem in some versions of ANT, due to a known problem with
command-line length on windows.

It relates to the path length that is used by ANT when compiling your
JSP.

If the path is longer than the max, then the initial '"' is there but
the final one is chopped. So if you have spaces in the path it will fail
as you say.  We hit this bug too.

My guess is you are using 4.1.24? (maybe 21/27 too, but it broke in 24
for me).  Try 4.1.29 - that seems better (embeds a newer version of
ANT), although I think theoretically its not entirely fixed. (I think
they put quotes around each element, but that could still mean the path
is chopped.  Not sure on this though.)

Your other apps worked because the their paths (e.g. package names) are
shorter, or they depend on fewer 3rd party JARs.


Hope this helps.

Re: Tomcat error with compiling JSPs

[Claire Wall]

sorry, i lied before - the JAVA_HOME variable is pointing to the bin folder
of the JDK.

we have just reinstalled Tomcat (4.1.2) again to a path that has no spaces
and it now works. However, this doesnt solve the problem because as stated
before, we cannot dictate what path our client has their tomcat installed
in.

Re: Tomcat error with compiling JSPs

[Claire Wall]

the classpath of the server only points to the bin folder of the JDK.

It still doesn't explain why this application isnt working and all of the
rest are, since all our applications are installed via a WAR file and I do
not change or set a class path for each application - I only change the
paths that need to be changed in web.xml and struts-config.xml for the
application. We have been developing this application on Tomcat on another
server and it works fine.

What reasons are there for the java compiler to not be able to compile JSP
files for a particular application as this appears to be the problem.

Re: Tomcat error with compiling JSPs

[Claire Wall]

i see what you're saying, but I've got about 6 applications running on
Tomcat on this server and they all work fine with no problems. This is the
first time that this has occured so I'd really like to understand what could
be causing this to happen. I'm assuming that it can't be anything coded into
my servlets/classes as these are already complied and shouldn't be compiled
by Tomcat when it's run, should they? I am using the getRealPath() method in
my servlets but this is also true of my other applications. i cannot change
the path of Tomcat because this application may well need to be installed on
a server where we can't dictate the install path of Tomcat so this is not a
solution.

Re: setting Form values from JSP for an object

[Claire Wall]

yeah i'm pretty familiar with nested tags having used them in situations
where I have objects nested within objects within my form e.g. to render a
tree structure. I thought it was a replacement for logic tags in these sort
of situations and have never considered using them elsewhere.

this works now thanks Matthias!

quick one though: what is the difference between nested & logic tags and
nested & html tags and in which situations would you choose to use nested
not the others?


cheers

setting Form values from JSP for an object

[Claire Wall]

Hi,

In have an ActionForm which contains an object called 'Details' like so:


public class DetailsForm extends ActionForm
{
private Details details = new Details();
   
public void setDetails(Details details)
{
this.details = details;
}

public Details getDetails()
{
return details;
}
}

 and the Details class contains two strings: name and reference, plus the getters and 
setters.


Now the problem i have is that in my JSP i can render these values fine in text boxes. 
I want the user to be able to change the values, submit the form and then save the 
changes. However, I cannot find the way that will call the setters of the Details 
object. Is this possible and how is it done? I have tried the following ways in my JSP:

Firstly, defined a bean and then used this bean definition to render my text boxes:









Secondly, didnt define the bean using  but instead did this:






This didnt work either, I'm assuming because only the setters are being called, and 
not get().set() like I want..


Is there any way to call the setters for a class within my ActionForm?? Any help would 
be appreciated.

determining the database driver in actions

hi,

is there a way to find out the database driver that is being used in my struts action 
classes?

the reason for wanting to be able to do this is that i would like to structure my 
class so that, depending upon the driver being used (or alternatively, type of 
DataSource) i could either write a Blob to the database (Oracle) or a BinaryStream 
(SQLServer or MySQL). 

is it possible to find out the DataSource's property's?

converting a FormFile to a Blob object

[Claire Wall]

hi,

I have a jsp page which uploads a file to a database. I have no problems storing the 
file in an SQLServer or MySQL database by using the setBinaryStream() method of a 
PreparedStatement. The file gets upload no problem.

However, when I try to upload this file to an oracle database (BLOB column) it does 
not work. I'm sure that i have to use the setBlob() method of the PreparedStatement, 
however, my dilemma is that I cannot find a way to convert my file from FormFile 
format to sql Blob format. Does anybody know how to do this as I've looked everywhere 
and haven't come up with a solution.

Any help would be much appreciated 


thanks

Re: simple question

[Claire Wall]

in the JSP you need to do:

<%
String hulp = (String)request.getAttribute("hulp");
%>

then you can use:

<%= hulp %>


often i do this (instead of the one above) to make sure u get the parameter:

<%
String hulp = (String)request.getParameter("hulp");
if(hulp==null) hulp = (String)request.getAttribute("hulp");
%>

datasources and oracle 9i

[Claire Wall]

hi,

i am using Oracle 9i as my datasource and have declared it in my struts-config as 
follows:


   


 









however, when i come to use this datasource in my struts actions, it gives me the 
following error:


Invalid Oracle URL specified: OracleDataSource.makeURL


im accessing the datasource in my actions like so (i use the same thing with an 
SQLServer datasource and it works fine):

DataSource dataSource = (DataSource)servlet.getServletContext().getAttribute("DB");


also, i have my oracle driver jar in the commons folder in tomcat - could this be the 
cause


Any help would be much appreciated!

Re: getServletContext() throws null pointer

[Claire Wall]

as i understand it, in order to retrieve the servlet context, you need to
use the ServletConfig to retrieve it like so:

config.getServletContext()


this sounds similar to a problem that i had where i was trying to log
something from a servlet, just used the log() method and it through an
exception pretty much like the one you are experiencing. however, by putting
config.getServletContext().log() it threw no exceptions...

Re: Wht does tag in web.xml means ??

[Claire Wall]

The  tag determines the order in which the specified
classes are run when the application first starts. so for example, say i had
two servlets which i wanted to start up immediately when the application
starts, i would do the following:


  myServlet1
  package1.myServlet1
  ...
  1



  myServlet2
  package1.myServlet2
  ...
  2


this means that myServlet1 would start up (run) first and then myServlet2
would start up after myServlet1. Often the ordering does not matter but if
you had a class which depended upon another to be up and running first, you
would need to order them correctly otherwise your application may not run as
expected and may well throw exceptions.

Re: forward vs redirect ?

[Claire Wall]

Hi Antony,

As a rule i always use just forward unless there is a specific need to
redirect to the page you're forwarding to.

For example, say i had an action which saved some details from a form to a
database. if the page is not redirected then if the user were to refresh the
page, the action would be called again and the data saved again. This
obviously i would not want the user to do so in this case i redirect the
page, so that if the user were to refresh the page, the save action would
not be called again.

The times when I would advise against using redirecting is when you're
storing objects on the request object in your action. If you redirect then
this information is lost. There are ways around this (like putting the
objects on the session rather than on the request object) but i try to cut
down on the amount of information being stored in the session.

There are probably some better defined uses of the redirect attribute and
when/where to use it, but the above is the general rules i go by, having run
into problems with both redirecting and not redirecting in the past.

hope this helps

Claire

Re: validation : the select field and checkbox field origin value lost...

[Claire Wall]

Ricky,

it is possible to do what you wish to do by doing the following (example
taken from a similiar thing that i did):

  
  
   
  

here i am iterating through a list of User objects in my form (my User
object is basically a class with the fields 'id' and 'username'). By using
 you can then use a JSP expression to set the value of the
 using the id of the . So in your case it will be
something like:


  
  





hope this helps

RE: request.setAttribute

[Claire Wall]

Hi Sporak,

The name which you have given your object is "myObejct" so when you try to retrieve 
this object off of the request, you need to do:

MyObject o2 = (MyObject)request.getAttribute("myObejct");

and not:

MyObject o2 = (MyObject)request.getAttribute("o");

Doing it this way (the way you have done it) would try to retrieve an object that has 
been given the key "o" but you have no object on the request with that name, so o2 
will be null. This is why you're getting the NullPointer exception.

Hope that helps

Claire :)

Subject: request.setAttribute



Hi there,

I have small problem with adding some objects to the request. I need to

store quite huge object into request variable

MyObject o = new MyObject();

o.setObjectName("name");

request.setAttribute("myObejct", o);

These are correct steps how to make it, aren't they? But the object MyObject

is really huge. Is it possible, tak the huge objects are not store into

request variable? Because when I store there object that surely exists, and

then I call

MyObject o2 = (MyObject)request.getAttribute("o");

if (o2 == null) System.out.println("NULL");

else System.out.println(o.getObjectName());

I always get NULL on output.

Can be there problem with the size of such object?

Thanks

Sporak
