Re: how to read uploaded FormFile InputStream multiple times?

[Vikram Goyal]

You are better off using FileUpload from the Commons package. Using
DiskFileUpload, you can set a threshold on the size of your files. If the
threshold is breached, the files will be saved in a temp location on your
hard disk from where you can access them as many times as you want. So you
could first save them to the database and then do whatever else you want.
You could even enhance the FileUploadBase to do exactly as you want, i.e,
write to the database and then still give you a handle on a perhaps new
input stream.

Re: html base element

[Vikram Goyal]

Hi Ashwani,

html:base is used to let the the browser know the location of the document
currently being seen by the user. This is important in the case of web pages
where there is an internal mapping between what a browser submits an action
to and what the user ends up seeing. These two may be different and ususally
are for web pages created with Struts.

For e.g., your app1/mystruts/logon.do may actually be referring to a page in
lets say app1/mystruts/dir1/welcome.jsp. Now, if you had images in this page
and they were mapped with relative paths in a directory as
../images/image1.gif, this would imply to the browser that image1.gif needs
to be retrieved from the directory app1/images (because the browser sees the
URL as app1/mystruts/logon.do and not app1/mystruts/dir1/welcome.jsp), when
you actually mean that it should be retrieved from app1/mystruts/images.

If you specify html:base, it makes an entry in the head section which is
used by all the relative urls in your page. So for example, if you did put
an html:base in the welcome.jsp as above, it would tell the browser that the
base url for all relative urls in this page is app1/mystruts/dir1 and not
app1/mystruts.

URL Rewriting

[Vikram Goyal]

Hello all,

A curious, but not totally unexpected, thing happens when I try to access my
Apache httpd-Tomcat (4.1.24) site for the first time via mod_jk2 connector.
Since Tomcat/Struts resorts to a URL rewrite of every link (because it
doesn't know that the browser is going to accept a cookie the first time),
all the static data is also appended with the URL rewrite since I am using
the Struts  and  tags. Somehow, the browser is not
able to resolve these URL rewritten links. Does anyone know why this would
be the case? If I do a refresh of the page, the images and other data is
retrieved successfully. If I run the site directly, i.e., on port 8080 on
which Tomcat is running, the data is retrieved without any problem even in
the first go.

If I remove the  tag and replace it with  tag and in essence
take out URL rewritting from the static data, that also works fine.

Any help, pointers appreciated.

Regards,
Vikram

Stackoverflow after DB inactivity

[Vikram Goyal]

Hello all,

I am getting a Stackoverflow error in Tomcat 4.1+ after a period of database
inactivity, typically (3+ hours). I am using Struts for the front end and
while the non DB access pages work fine, as soon as access to a page is
requested where data is to be fetched from the database, I get the
StackOverflow. This is not random and I can replicate the error. The error
goes away however, when I try to access the same page twice or thrice and
everything works fine after that.

This error is appearing on both windows and linux, i.e., Tomcat is on these
machines, although the database, MySQL 4 is running on linux 9. The DB
access is through a connection pool I set up in Struts config for my
application using org.apache.commons.dbcp.BasicDataSource.

The stack trace follows:

Re: StackOverflow error?

[Vikram Goyal]

I get the same error when I try to execute a DB query via a form. I am using
Struts1.1rc1, Tomcat 4.1.24 and MySQL. I initially thought that the error
was because the connection was lost to the DB server and therefore I had put
autoReconnect=true in the DB URL. But that did not stop the problem.

I get the error only once when the server has been inactive overnight and if
I retry, it works fine.
Maybe thats why I have not tried to debug it too much. :)

Justifying Tag Libraries - Slightly long

[Vikram Goyal]

Hi all,

After failing to convince my boss otherwise about his fear of slowing down the 
performance of an internationalizated web application by the use of Struts tags, I 
decided to set up a stress test environment to prove that tags do not have that high a 
performance issue. However, much to my dismay and surprise, I found that my boss was 
correct! Tags, do indeed, affect performance, and we are not talking about nanoseconds 
of difference. Here is my test environement and how I went about doing so:

Single Client Machine: Windows XP Pro - with 512 MB RAM, Pentium 4 (1.7Mhz),  IE 5.5.
Server: Windows XP Pro running Weblogic 7.1 with 512 MB RAM, Pentium 4 (1.7 Mhz)

Stress Test Tool: Microsoft Web Application Stress Tool

Struts Version: Struts 1.1b2.

Testing method:
1. Ran 1000 threads on a simple JSP page, which used bean tags to render the content 
of the page. This is a simple page, which contains a lot of text, all of which is read 
from ApplicationResources.  This page was ideal for the test as it had the most tags 
(40+).
2. Ran 1000 threads on the same page. However, this page, is static, meaning, that the 
page accessed was pre generated using an internationlation mechanism that simply 
generates static html pages for different languages and puts them in respective i18ned 
directories. So a user who understands spanish would go to the document root for 
spanish and so on.

Well, the results:
Without boring you with all the figures, let me just put get into the result analysis. 
Overall, I found that for the first case, the difference between the time taken to get 
the first byte(ttfb) of the page and time taken to get the last byte(ttlb) of the 
page, was vast. In the second case, this difference was miniscual. This meant, that in 
the first case, the pages were received faster, but took longer to finish downloading. 
In the second case, the pages took slightly longer to come through, but finished 
downloading much much faster than the first case (150 times faster than first case).

I ran the tests three times for 25, 100 and 1000 clients and all the tests results 
gave the same analysis.

With these figures in hand, I had no answer to my boss's snide remarks about uh, hmm 
... well never mind, except to say that I had no answer.  What I am hoping from the 
list is if someone can help me understand why this would happen, would this be as 
expected and well, how do you still justify the usage of tags.

Best Regards,
Vikram Goyal

 at _web_22dinf._jsp._mycraft__jsp._jspService(/WEB-INF/jsp/mycraft.jsp:26)

I understand that while using a TreeMap, the values returned are part of the
Inner class Entry. But why should this give me an error here?

My logic iterate looks like:



   

 
  



where user is the bean that contains a TreeMap property of bookmarks.

Any help appreciated.

Regards,
Vikram

Re: Dynamic Value for logic equal

[Vikram Goyal]

Thanks David/Edgar,

I have actually done it in a scriptlet, but it is departing from the idea of
keeping JSP's scriptlet free. I am surprised that there is no generic way of
handling this in Struts. I always assumed that it would be till I actually
had to do it !!

The EL approach seems better but how was this tackled before Struts-EL came
into picture? I am guessing the scriptlet way?

Regards,
Vikram

Dynamic Value for logic equal

[Vikram Goyal]

Hello All,

I have searched the list for some time now and could not find a conclusive
answer for my problem. I am hoping someone else has come across this and can
help me.

When displaying information about a User, I need to display the Label for a
Country Code. This should be simple enough. However, the User bean contains
only the country code. To get the Country label, I need to iterate over the
Country Data static collection, which stores information about each country
as a LabelValueBean. This collection is stored in session scope.

However, the problem is that while inside the logic:iterate tag, the
logic:equal tag does not accept dynamic value for the 'value' attribute. The
processing should be like this:







The USER.GETCOUNTRYCODE is the problem part. I have tried value=''. This does not work, as it seems that it
is parsed as is by the compiler. I also tried using bean:define for the
country code and then passing that in but that fails as well.

I ended up writing a scriptlet around it to solve the problem, but am not
convinced that it is the best way to go about it.

Any help would be greatly appreciated.

Regards,
Vikram

Re: Reroute to login page

[Vikram Goyal]

You could also use the inbuilt ForwardAction.

Details are in the javadocs of Struts.

Resource temporarily unavailable

[Vikram Goyal]

All,

This is probably off topic and if so I apologize.

I shifted my hosts from a non JSP one to a JSP one short time ago.  The deal
was 500 MB disk space, 15GB transfer, and private JVM and Resin for 235 USD
a year. Too good to be true? Probably is??

Anyways, this is the problem:

I deployed my Struts specific test war file ( which opens up 10 connections
to the database ) on the server and as soon as I restarted Resin, I started
getting these messages on the screen whenever I tried running a command:

[: =: unary operator expected
bash: fork: Resource temporarily unavailable

Tech support tells me that it is because I have over stepped my allocated
processes (30). Now my question is, would Struts start something behind the
scenes that could make these processes? I have been taking the high stand
and saying that it is not possible that Struts would do such a thing but I
dont know for sure. Tech support just refuses to believe that and think that
is my code.

On a side note, does anybody know of a decent host that would give you a
private JVM for a decent price and good tech support and runs Struts without
problems?

Thanks for any help on this.

Regards,
Vikram
