microsoft sqlserver driver struts
Hi, I am trying to use microsoft's jdbc driver with my struts application, but to no avail. Here is my datasource definition: data-source key=DB type=org.apache.commons.dbcp.BasicDataSource set-property property=description value=My SqlServer pool/ set-property property=driverClassName value=com.microsoft.jdbc.sqlserver.SQLServerDriver/ set-property property=url value=jdbc:microsoft:sqlserver://SERVERNAME:1433;DatabaseName=DBNAME/ set-property property=username value=xxx/ set-property property=password value=xxx/ set-property property=maxActive value=20/ set-property property=maxCount value=20/ set-property property=minCount value=2/ set-property property=maxWait value=5000/ set-property property=defaultAutoCommit value=false/ set-property property=defaultReadOnly value=false/ /data-source 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
Re: microsoft sqlserver driver struts
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. - Original Message - From: Mark Lowe [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, February 27, 2004 11:29 AM Subject: Re: microsoft sqlserver driver struts Does the error get thrown when you attempt to access the data source or at startup?

Re: microsoft sqlserver driver struts
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..

Re: microsoft sqlserver driver struts
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
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! :) - Original Message - From: Claire Wall [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, February 27, 2004 3:19 PM Subject: Re: microsoft sqlserver driver struts 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.

Re: How do you submit a page and not change values
you can use the html:submit and html:cancel 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'...
html:form action=/saveDetails
html:text name=DetailsForm property=name/
html:submitSubmit/html:submit
html:cancelCancel/html:cancel
/html:form
in struts-config you define your actions and where you wish to forward to
depending on which button the user clicked on:
action input=/xxx.jsp name=DetailsForm path=/saveDetails
scope=request type=xxx.xxx.SaveDetailsAction validate=false
forward name=success path=/xxx.jsp /
forward name=cancel path=/yyy.jsp /
/action
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 :)

Subject: How do you submit a page and not change values
If you use either html:button, html:submit or html:cancel buttons they
generate input type=button html.
So how can you create a screen for example with 1 field and 2 buttons, a
submit and a do Not Submit button, both of which navigate the user to a
results screen?

Re: Getting the CheckBox Collection Value in FormBean Class
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:
html:checkbox name=FormName property=checkboxes value=???/
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: Getting the CheckBox Collection Value in FormBean Class
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).

Subject: RE: Getting the CheckBox Collection Value in FormBean Class
Yes Claire,
I am doing like that only.This is my jsp,contains the
code.
I am nested inside the iteration.
FORM BEAN
public String[] getDeletereqs() {
return this.deletereqs;
}
public void setDeletereqs(String[] deletereqs) {
this.deletereqs=deletereqs;
}
JSP
logic:iterate id=allrc name=allreqcand
tr align=left
td
html:checkbox name=allrc property=deletereqs
value=check
/
/td
/tr
/logic:iterate
Then in the action, i want to check what r all the check boxes checked.
How
can i do that one.
Shall i use the request.getParametervalues();
Any othet option u know, how to perform in action.
Mail your opinion.

Subject: Re: Getting the CheckBox Collection Value in FormBean Class
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:
html:checkbox name=FormName property=checkboxes value=???/
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: html:options and html:select
you can do the following:
html:select name=FormName property=xxx
logic:iterate id=product name=FormName property=ListName
option value=bean:write name=product
property=id/bean:write name=product property=name/
/logic:iterate
/html:select
'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 logic:iterate
tag. For every object in your list an option 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: Making the fields non editable dynamically using a form bean element
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: logic:equal name=FormName property=xxx value=true % flag = true; % /logic:equal logic:equal name=FormName property=xxx value=false % flag = false; % /logic:equal and then in your html:text elements do this: html:text property=xxx disabled=%= flag %/ 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!)

weird Tomcat prob
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: servlet servlet-namehasAttachments/servlet-name servlet-classHasAttachmentsServlet/servlet-class load-on-startup5/load-on-startup /servlet It loads up fine - the servlet is found as it is logging to the log file that it is loaded.

Re: weird Tomcat prob
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 :) claire - Original Message - From: Max Cooper [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, January 16, 2004 10:08 AM Subject: Re: weird Tomcat prob My guess is that it is finding and executing the servlet, but that something goes wrong while the servlet is being processed.

Re: Tomcat error with compiling JSPs
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: Tomcat error with compiling JSPs
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.

This seems telling:

It seems like some kind of path with a space in it is being passed to the

javac -classpath C:\Program Files\somelib\lib.jar ...

However, I would kind of expect the error to be invalid flag:
Files\somelib\lib.jar in that case, since the C:\Program part is before
the
space. Could you have some kind of funky classpath like C:\dir\lib.jar;
C:\Program Files\poop\stuff.jar (note the space after the ';'). Are you
setting the classpath for the server process yourself, perhaps by starting
Tomcat using your own script (rather than startup.bat)? Or do you have
some
strange classpath in your environment before you start Tomcat?

Re: Tomcat error with compiling JSPs
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
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.

Subject: Re: Tomcat error with compiling JSPs
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.

setting Form values from JSP for an object
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:
bean:define id=detail name=DetailsForm property=details/
html:text name=detail property=name style=width:150px/
html:text name=detail property=reference style=width:150px/
html:submitbean:message key=button.save//html:submit
Secondly, didnt define the bean using bean:define but instead did this:
html:text name=DetailsForm property=details.name style=width:150px/
html:text name=DetailsForm property=details.reference style=width:150px/
html:submitbean:message key=button.save//html:submit
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.
Claire :)
Re: setting Form values from JSP for an object
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

Hi Claire
have you tried the nested-tag?
like this?
nested:form action=/nested
nested:nest property=details
name: nested:text property=name/br/
ref: nested:text property=reference/br/
/nested:nest
html:submit/
/nested:form
your formBean (detailsForm) is associated action-path /nested

Subject: RE: converting a FormFile to a Blob object
You have to insert the record using an empty LOB, then select the record
for
update and write the byte stream to the LOB.
Here's an example insert method from my DAO that I used for the same
purpose
recently.
Might not be the most efficient or prettiest code out there, but it works
like a champ. We've tested it with image files, Word, Excel, PDF, etc. The
VO being passed in has a FormFile field DataFile, and a bunch of other
fields for name, type, etc.
I had to turn autocommit off to get this to work. On another project I did
something similar for CLOBS, but the transaction was handled through
session
bean, so in that case take those lines out.
public int insert(StatsDocumentsVo vo) throws CapException,
SQLException
{
long docId = getNextDocId();
Connection conn = null;
PreparedStatement ps = null;
ResultSet rs = null;
BLOB binLgObj = null;
OutputStream out = null;
int rc = -1;
int ii = 1;
try
{
conn = getConnection();
conn.setAutoCommit(false); // to avoid ORA-01002: fetch out
of
sequence
/*
* Insert the record with a blank holding spot for LOB
*/
ps = conn.prepareStatement(SQL_EXT_INSERT);
ps.setLong(ii++,docId );
ps.setString(ii++,vo.getDescr());
ps.setString(ii++, vo.getMimeType());
ps.setString(ii++,vo.getLastUpdUser());
ps.setString(ii++,vo.getDocumentName());
ps.setString(ii++,vo.getOsoNumber());
ps.setBlob(ii++, oracle.sql.BLOB.empty_lob());
log.debug(Ready to execute the insert statement (empty
BLOB).);
rc = ps.executeUpdate();
/*
* Get the record back from the database
*/
ps.close();
ps = conn.prepareStatement(SQL_GET_BY_PK);
ps.setLong(1, docId);
log.debug(Ready to execute the select statement to get ref to
the empty blob.);
rs = ps.executeQuery();
rs.next();
// get empty blob pointer out of result set
log.debug(Ready to get empty blob out of result set.);
binLgObj = ((OracleResultSet)rs).getBLOB(DATA_FILE);
// open up the output stream to write into blob
out = binLgObj.getBinaryOutputStream();
// write file byte[] into the blob
log.debug(Ready to actually write the file's byte[] array
into
the blob.);
out.write( ((FormFile)vo.getDataFile()).getFileData());
log.debug(Closing output stream.);
out.close();
// commit the xaction
log.debug(Commit the xaction to the DB);
conn.commit();
log.debug(Closing result set, prepared statement.);
rs.close();

Re: Wht does load-on-startup tag in web.xml means ??
The load-on-startup 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: servlet servlet-namemyServlet1/servlet-name servlet-classpackage1.myServlet1/servlet-class init-param.../init-param load-on-startup1/load-on-startup /servlet servlet servlet-namemyServlet2/servlet-name servlet-classpackage1.myServlet2/servlet-class init-param.../init-param load-on-startup2/load-on-startup /servlet 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 ?
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 - Original Message - From: Antony Paul [EMAIL PROTECTED] To: struts [EMAIL PROTECTED] Sent: Monday, December 01, 2003 1:28 PM Subject: forward vs redirect ?

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.

Re: validation : the select field and checkbox field origin value lost...
Ricky, it is possible to do what you wish to do by doing the following (example taken from a similiar thing that i did): logic:iterate id=user name=myForm property=users bean:define id=id property=id name=user/ html:option value=%= (String)id %bean:write name=user property=username//html:option /logic:iterate 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 bean:define.. you can then use a JSP expression to set the value of the html:option using the id of the bean:define. So in your case it will be something like: logic:iterate name=authors id=author bean:define id=an_author property=author_id name=author/ html:option value=%= (String)an_author % bean:write name=author property=author_name / /html:option /logic:iterate hope this helps claire - Original Message - From: Ricky [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, November 28, 2003 4:37 PM Subject: Re: validation : the select field and checkbox field origin value lost... thanks for helping me.. and then i search a question like this at achieve mailing and it told me use html:option, and i test it, the solution is ok, but, what a pity, i can't use html:option , because.. if i use it...it will show me the exception :equal symbol expected in the jsp page , i use a logic:iterate to add my option element, and can't nested a html:option in it. just like this. logic:iterate name=authors id=author html:option value=bean:write name=author property=author_id /bean:write name=author property=author_name //html:option /logic:iterate if i use that code above , it shows me the exception... so i have to abandon the html:option tag, what a pity... :( i can only use common html syntax option, so my first problem you replied me come out.. and could anyone have a better solution about my case? or i can change the login:iterate to java script as java.util.List to use a loop to get my select option...in fact, i don't want insert a java script in my page, all of my page are using taglib, none java script within my jsp page and what about nested tag... any other better way? - Original Message - From: Janice [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, November 29, 2003 12:15 AM Subject: re: validatation : the select field and checkbox field origin value lost... Hi Ricky, After validation, struts will display whatever you specified in the input parameter of your action mapping. If you specify an action (like displayForm.do), then all of the processing that is done in that action will be performed before the page is shown. I suspect this is why the values on the form that were changed have gone back to their defaults. What you probably want to do instead is specify the .jsp page that you would normally forward to upon success (like myForm.jsp). hth, Janice - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
