Re: UTF-8 and Encoding Problems
Are you using Tomcat? If you do some searches, you'll probably turn up other postings on this topic. I can't remember all the ins & outs, but supposedly the browsers incorrectly supply encoding information in their requests to Tomcat (ours were POST requests), and Tomcat by default assumes ISO-8859-1 encoding for the submitted form data. This gives you garbage data for anything outside plain ASCII, if your browser sends it in UTF-8. I found some webapp filter class that works with Tomcat to coerce the character encoding (or Tomcat's perception of the encoding) for all requests to UTF-8, to match all of our pages and forms. I can send you our filter and the web.xml entries separately; if you want them, just e-mail me. There may be better solutions now with Tomcat 5, but we have just kept on using this old filter, and it seems to do the trick. (Now that I think about it, I think this filter is/was supplied with the Tomcat source distribution, maybe.

Re: dynamic query help
off the top of my head, start with this (easiest) to get it working. If it
performs well, you can leave it like this, but for better performance take
a look at http://cocoon.apache.org/2.1/userdocs/xsp/esql.html#Groups
which will let you use a single join query to accomplish your goal.

Hi list,
I have this ESQL query to my DB:
select id, area from ukareas order by area
This just returns the column rows "ID" and "AREA"
I also have this table which maps tables ukareas and county
create table navmap (
aid integer,
cid integer,
primary key (aid,cid),
foreign key (id) references ukareas(id),
foreign key (id) references county(id)
);
I then have this query:
select county from county, navmap where navmap.cid =
county.id and aid= 'X ' order by county
Where 'X' is the result of ukareas.id column, so essentially I'd like
to do something like
for (int i = 0; i < id.length; i++) {
//where id = ukareas.id
select county from county, navmap where navmap.cid
=
county.id and aid= 'id[i]' order by
county
}
essentially I'd be outputing something like:
South - East
Surrey, Kent, etc...
Anglia
Norfolk, Suffolk, etc...
I have a very, very rough idea of how I could do this but need some
pointers.
Many thanks all.

C2.1.5 - build.sh bug
There is a bug in the build.sh build script. Sorry if this has been covered before; this is my first build of a 2.1.x system. The build.sh uses /bin/sh, which on Solaris and other traditional *nix is typically Bourne shell. The build.sh is not compatible with Bourne shell, however. I didn't check it for all errors, but the line export ANT_HOME=tools breaks Bourne shell. The correct syntax is ANT_HOME=tools export ANT_HOME Perhaps the INSTALL.txt should mention this, and some workarounds? I simply changed the build.sh to use /bin/bash, which works on my system. -Christopher - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Extending ESQL - how (if at all)
There are a couple of ways I think are easier to extend ESQL. In particular, I think it is useful to have all of your extensions in a separate place, outside the jar file. Otherwise, it is easy to lose track of the changes you have made. So one option is to bring the esql.xsl outside the jar, and change cocoon.xconf to point to the new location (I assume that it still works this way in 2.1, I am still using 2.0.x). To take it one step better, create your own stylesheet that contains your single template, and use to import the esql.xsl. Again, change cocoon.xconf to use your stylesheet.
If you start getting a lot of these, you might consider creating a "wrapper" logicsheet. In essence you create a stylesheet with your own namespace, like "jeff.sql". The logicsheet defines or redefines templates as needed, and simply creates ESQL tags to re-use the esql functionality. You can have one template that merely passes forward to ESQL any tags that your logicsheet doesn't explicitly redefine. This has advantages and disadvantages; one disadvantage is that you have to copy over any named templates from ESQL that you need to make your custom templates work, e.g., "get-nested-string". In your case, you are using a couple of named templates, but I wonder if you could do a wrapper template like:
().getTime()
I don't have the esql.xsl right in front of me, so I don't know if this works or not. If not, maybe ((java.sql.Timestamp)()).getTime(). You have to get a bit creative
We have a logicsheet like this, that gives us various extended features. For instance, it handles all of the connection pool stuff, so that I don't have that explicitly in each of my XSP pages. I also used it to get a "short form" for update queries, e.g.,
update blah set blah = blah;
and it does other stuff, too. If you are interested in this, here's a skeleton:
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

Subject: Extending ESQL - how (if at all)
Hello all.
I'd like to use XSP/ESQL to retrieve a date from a database (might be Oracle or
MySQL) in "Unix epoch" format, i.e. milliseconds since 1/1/1970. Unfortunately,
that's not a format available in java.text.SimpleDateFormat, so it doesn't seem
possible to retrieve it using the tag.
I know that this could be done with a separate XSL transform, but for
performance reasons, I'd prefer not to have to convert back to a Date object and
then back to a String representation; I'd like to work with the Date object
(actually java.sql.Timestamp) retrieved from the database.
So I've tried adding this to esql.xsl:
returns the value of the given column as milliseconds since the
epoch.
="esql:row-results//esql:get-epoch|esql:call-results//esql:get-epoch">
.getTimestamp
().getTime()
And here's the part of my XSP that uses the new tag:
A few questions:
1. Apparently I'm missing a step somewhere, because I'm just getting the
tag passed straight through when the pipeline runs. (Yes,
everything else works.) I've restarted Tomcat, rebuilt the databases block, and
copied the new databases-block.jar into WEB-INF/lib, to no avail. What do I need
to do to get this change reflected in running code?
2. Am I doing this the hard way? Is there an easier solution that I'm missing?
(Remember that I really don't want to do it in a separate transform, for
performance reasons.)
3. If this actually is a worthwhile idea, how would I go about submitting it?
(Details: Cocoon 2.1.4, Tomcat 4.1.29, Sun Java 1.4.2-b28 on SuSE Linux 9.0,
kernel 2.4.21.)
Thanks in advance for any help.
Re: Dynamic connection to the database
What are you using: ESQL, SQLTransformer, ...? For ESQL at least, and I imagine for SQL Transformer, you don't have to use a pool connection. You can dynamically provide the jdbc connection parameters. The downside is that you make a new connection on every request (unlike a traditional client-server application where your login session is maintained from page to page). Also, you have to maintain db accounts for everyone who needs to log in. We had a similar need in our application. I did an extension to ESQL that uses a java SQL parser to take apart each query, and rewrite it to add in the auditing information (after looking to see if the tables in question have the auditing fields), using the web app login name instead of a separate Oracle account. That way we can continue to use the pool connection. This was the hard way, but it does the job. -Christopher |-+---> | | Yves Vindevogel | | | <[EMAIL PROTECTED]| | | lements.be> | | | | | | 05/05/2004 05:37 AM | | | Please respond to | | | users | | | | |-+---> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: Dynamic connection to the database | >--| Hi, I need to keep track of who changes records in my database (I use postgres).

Re: Better alternative to ESQL?
FWIW, that conversation did not include everyone using Cocoon and/or reading the list. It may be that the folks joining in the conversation were those with similar approaches. My attitude is the best tool for the job is the one that meets your needs. Since many of the tools recently mentioned were not available 1-2 years ago, we developed a lot of our own designs to tackle the same sorts of problems in our environment. We make heavy use of XSP, logicsheets, and ESQL. At this point our designs are pretty mature and, of course, are a custom fit for our needs. If you have established software that is working, you probably have a good idea where the most "pain" is - where the code is difficult to modify and extend, where you spend the most time, etc. Or you may be adding new features with very different requirements than before. In these cases, it is probably worth examining the new tools to see if they offer a solution to your particular problems. Otherwise, if it ain't broke In our case, I am interested in some of the tools that help with forms and form validation, which is an area we are very weak on, so I may examine these in the future. However, on site navigation, layouting, etc., I feel our designs are working very well, so I probably won't look for something else. Here's my vote for XSP: it is general-purpose, powerful, flexible, and extensible (with all of Java available to you). It doesn't solve a specific problem, but it can be used to solve almost any problem. -Christopher |-+> | | "Derek Hohls"| | | <[EMAIL PROTECTED]| | | a> | | || | | 05/03/2004 07:28 | | | AM | | | Please respond to| | | users| | || |-+> >--| | | | To: <[EMAIL PROTECTED]> | | cc: | | Subject: Better alternative to ESQL? | >--| There seems to be a very a strong "current of opinion" on the list at present (April 2004) saying that XSP is not really a suitable component of a "well archictectured" Cocoon application.

Re: document() in xsl:variable -> low performance
Ouch! I make heavy use of the document() function for aggregation.
Sitemap aggregation would be a pain to maintain, because the stuff I need
to aggregate comes rather late in the pipeline (layout information),
whereas the generation and early transformation steps can vary a lot.
XInclude/CInclude could work, but I like the cleanness and flexibility of
using the document() function.
Does it help any to take another variable on some subtree of the variable?
Does it make a difference if you use xsltc?

I'm guessing that I could do this with a logic sheet? Or should I move
this to woody / cforms?

Re: Deal with variable page content??????????????
I don't know which Cocoon technologies you are currently using, but this hsould be fairly straightforward in Java (using XSP). You can ask the request for a list of all parameters, and iterate through the list and take the appropriate actions.

Re: XSP and logicsheets namespaces inclusions
Olivier, we are using C2.0.3, and struggled with this problem for over a year. We have created many logicsheets, many of them using each other, and this problem was frequent and frustrating. The problem seems to be caused by some kind of race condition, and we learned we could reproduce it reliably by hitting the same (uncompiled) page twice quickly, i.e., the second request before the compilation is complete. The fix for us turned out to be a cocoon.xconf setting which was recently discussed on the list as buggy. :( The setting is the use-store setting for the xslt-processor. Apparently setting this to true improves performance, but is known to be buggy. Well, setting it to false fixed the bug for us. Please let me know if this works for you. - Christopher |-+> | | Olivier Billard | | | <[EMAIL PROTECTED]| | | r> | | | Sent by: news| | | <[EMAIL PROTECTED]| | | rg> | | || | || | | 04/20/2004 09:49 | | | AM | | | Please respond to| | | users| | || |-+> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: XSP and logicsheets namespaces inclusions | >--| Hi again, I have an XSP that includes some logicsheets.

Re: ESQl and Stored Procedures
Carlos,
just for background, can you do a simple select or update query using ESQL?
I ask only because you aren't getting a compile error, which you would
normally expect when an appropriate class isn't available. What this
reminds me of is what happens when the Oracle jdbc classes aren't loaded in
the web application. The JDBC stuff (through some sort of black magic I
don't know a lot about) figures out which class to load based on your db
url and then goes to load it. Maybe that is where the error is coming
from. If so, then you shouldn't be able to do a simple query either.
If that is the case, then you need this section in your web.xml file:
load-class
oracle.jdbc.driver.OracleDriver
I guess another possibility (which would also prevent simple queries) is if
your pool is not set up correctly, e.g., it has an incorrect db url.
If you are able to do simple queries, then it may be something more
specific to doing a stored procedure call, which unfortunately I have no
experience with (through ESQL, anyway).

Hi,
I'm trying to use a stored procedure for making an update in an Oracle
database.
Here is the xsp+esql code:
http://apache.org/xsp";
xmlns:xsp-request="http://apache.org/xsp/request/2.0";
xmlns:esql="http://apache.org/cocoon/SQL/v2";>

sca
String app_id = request.getParameter("app_id");
String user_id = request.getParameter("user_id");
if (app_id != null || user_id != null) {
{call bookmark.update_bookmark_list(\
user_id,\
\
app_id)}
}
else {
Parameters does not exists
}
I got the following result (in the web page):
XML document must have a top level element. Error processing

Could it be that the embedded in the block is the
culprit? I read somwhere that that is not a wise combination. (which is
logical as in an xsp:logic you don't need an xsp:expr).
Please note: I did not try this, and have never used the esql:call. But
it seems
that all tags are closed - so this might just be it.
You could in stead prepare all your calls in advance in a logic block
and call on
those strings when needed - outside of the logic block with .
Just my 0.02c (and that's not much).

Re: Including Fragments
In general, all the XML tools require well-formed XML, even for fragments. The only way around it is to work in java, concatenating strings, and then running the whole string through the XML parser, which is silly to do without a pretty specific need. It would be a lot easier to use XSLT for this, and keep your headers & footers together for well-formedness. There are a zillion different approaches.

Re: Sql type for request parameter with multiple values
I doubt it. If you are doing this using SQL actions or the like, you'll probably have to write your own action to do the conversion. Otherwise, consider using XSP+ESQL or XSP+SQL Transformer.

Re: Conditionnal esql-query ?
Because you can't :)
Keep in mind what is really happening here. The ESQL logicsheet is turning
all of this into java code. What kind of java code probably happens with
the esql:query tag? Well, it probably needs to obtain a String which it
can then pass into JDBC as the query, righ?. Now, try this in java:
String query = if (...) { ... } else { ... }
See the problem?
However, the problem suggests the solution. You CAN do it, but only if you
make your if/else into an expression, using the question mark operator,
e.g.,
(id_blog_news == null) ? ... : ...
Better, though is to just pull the entire query and if/else block outside
the esql code, e.g.,
String sql;
if (id_blog_news == null) {
sql = "SELECT .";
} else {
sql =
}
then you can do
sql
You can also put your if-else around the entire esql:execute-query block,
that is, you can have one esql:connection around all of your individual
queries, for what small savings in code that is.
Finally, though, keep in mind that your dynamic SQL code potentially
provides opportunities for hackers to modify your SQL in ways you did not
intend by what they supply in the request parameters. So you might be
better off going back to your first code that does an if/else around the
whole SQL block, and using instead of inlining SQL using
.

Re: ESQL INSERT
1. Check your logs, perhaps the error message in one of them. You might also try removing your element; perhaps it is masking an exception that you'd otherwise see. 2. Make sure your pool, xsp, and esql setup is correct; can you do a simple SELECT query successfully in place of the INSERT? 3. You say the query works by hand; are you logging in using the same account as your pool user? Otherwise you might have a permissions problem. 4. Is the code below copied from your source?

entering them on the form!), so the database is probably getting syntax
errors, which I think you should be seeing. You have two choices to fix
this:
Each place you have an expression like news_title
1. (potentially a security risk) change to
'news_title'
2. (much better) change to
news_title

RE: avoid setting the password in jdbc settings in cocoon.xconf
Here's some sample code of what I mean - with this code, you can pass in the dburl, username, and password from a form:
xmlns:xsp="http://apache.org/xsp"
xmlns:esql="http://apache.org/cocoon/SQL/v2"
>
request.getParameter("dburl")
request.getParameter("username")
request.getParameter("password")

I will try it, however it would be good to have an example of how you
define the connection for ESQL in an tag.

Re: how do you set up your version control?
We keep our entire webapp in CVS, including the jars. We work with the project under Eclipse, using the Tomcat plugin. Eclipse does a terrific job with CVS. The only stuff we don't currently keep in CVS (but we want to eventually) are the Tomcat conf files and supporting libraries directories (e.g., common/endorsed). The advantage to keeping the jars under version control is pretty obvious once you start dealing with upgrades to various components, such as jdbc driver jar files, etc., or if you ever tweak resources stored in the cocoon.jar (e.g., logicsheets). We also have a few java classes, and having the entire project in Eclipse, we can modify the source in WEB-INF/src and have it automatically compile to WEB-INF/classes. In this case, only the source gets stored in CVS, and Eclipse recompiles the code whenever you check out modified source from CVS. This would require a little extra work if we built our .war file directly from CVS, but we use the Sysdeo Tomcat plug-in to build the .war file from Eclipse, and it gets the compiled stuff just fine. -Christopher |-+> | | Dan | | | <[EMAIL PROTECTED]| | | drice.net> | | || | | 03/17/2004 02:07 | | | PM | | | Please respond to| | | users| | || |-+> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: how do you set up your version control? | >--| Hi, How are people setting up version control (CVS, SVN) for their projects?

Re: binding params in dynamic queries in ESQL
Well, for what it's worth, using Oracle's jdbc drivers and putting a second query in the esql:query block results in this error: java.sql.SQLException: ORA-00911: invalid character I separated the two queries using ";", which is presumably the invalid character Oracle is complaining about. I can't imagine any other way of separating the two queries. Any thoughts? I can't find anything in the java docs for java.sql.Connection.prepareStatement() that specifically forbids having multiple queries, so you may be right about it being driver dependent. Our app seems to be pretty safe from this particular attack, regardless. We actually run the query through another parser (too long to explain why) that results in only one query getting executed, regardless of what is in the query block (I had to work around this to get a good test and produce the exception noted above). I also looked hard (since I was looking) at every possible way I could mess with the query parameters to modify the way the SQL executes, but it appears that we do enough stuff to the request parameters (stripping quotes, parsing into integers, etc.) that there isn't much hacking possible. (Hopefully nobody will take this as a challenge, but notice I'm NOT listing any URLs for my app here!) Of course, all of our update/delete queries are using bound parameters! -Christopher Torsten Curdt <[EMAIL PROTECTED]> Sent by: news <[EMAIL PROTECTED]> 03/05/2004 09:15 PM Please respond to users To: [EMAIL PROTECTED] cc: Subject: Re: binding params in dynamic queries in ESQL > I thought that ESQL used JDBC prepared statements, regardless of whether > you have bound parameters; That's right > while it won't protect you fully, won't it throw > an exception if it receives two queries (which this attack results in)?

I thought that ESQL used JDBC prepared statements, regardless of whether you have bound parameters; while it won't protect you fully, won't it throw an exception if it receives two queries (which this attack results in)? Perhaps I'm wrong on this point. It isn't ideal, but if your dynamic SQL is only doing selects, and only against data that isn't sensitive, then the worst case scenario is perhaps an attack that slows your server down (and the attacker would have to know a good deal about your schema to do that).

Re: binding params in dynamic queries in ESQL
Rebecca, It might take some time to prove it, but I'm pretty sure you can't do what you are trying to do with ESQL. I've gotten pretty deep into the ESQL logicsheet, and it looks for specific tags in specific relationship to other tags, e.g., it will look for the esql:parameter tags as children of an esql:query tag. Since the logicsheet knows nothing of your java logic, it will generate parameter setting code for each esql:parameter tag, regardless of whether you manage to put logic around the tag to switch it on or off in the query itself. So whatever you do, you will get errors if you try to have a dynamic number of parameters in a single esql block, because the parameter setting code will not match the query. (The existence of the parameter tag creates java in more than one place, but your xsp:logic conditional java code will only be copied into the query area - assuming the logicsheet will even honor those blocks.) So, here are your choices as I see them: 1. Abandon parameter binding, and just build the SQL string dynamically (which is what we do with this situation) 2. Create a separate ESQL block for every possible combination of parameters, then choose which ESQL block to run via java logic 3. Extend/modify the ESQL logicsheet to meet your needs; you can get the esql.xsl out of your cocoon.jar file, modify it, then modify cocoon.xconf to point to your modified logicsheet 4. Don't use ESQL (would SQL transformer work for you?) Sorry I don't have an easy solution for you. -Christopher R Hunt <[EMAIL PROTECTED]To: [EMAIL PROTECTED] .edu>cc: Subject: binding params in dynamic queries in ESQL 03/05/2004 11:27 AM Please respond to users Thanks in advance for any help on this.

Re: Passing values into an XSP logic sheet
Andrew, sorry I didn't reply to your previous mail - I got very busy yesterday. I looked at the files you sent, and I saw some things, but it looks like you've moved on. In your current posting, I think the problem is the order of execution. In your logicsheet, you are putting in code to look up the artist details in an xsp:logic block directly inside the xsp:page block. This puts all of that code at the class level, so it is executed when the page object is first instantiated. The code that provides the artistID for lookup, on the other hand, is inside the 'page' element, which means it is put in the generate() method of the page class, which gets called to generate the page. By the time it is called, though, all of your artist detail variables have already been set. Here's a rewrite/simplification that may help: 1. XSP Page (snippet) http://apache.org/xsp"; xmlns:artistDetails=" http://www.beyarecords.com/artistDetails/1.0"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:util="http://apache.org/xsp/util/2.0"; > int artistID = Integer.parseInt(); artistID ... 2.

Re: Re[2]: Very strange IE problem
Bastian,
here's the essence of the code, implemented in XSP. We have a sitemap
entry that generates from this XSP whenever the URL is of a pattern
"/pleasewait/*". We can then do a pleasewait before any page we want by
simply putting "/pleasewait" in front of the usual URL.
The key line is the one that adds a "refresh" header to the response, with
a timeout of zero. (This is the same mechanism that website use to
redirect you to a new URL, but usually with a timeout of 5-10 seconds.)
When this page loads (in every browser we've tried), it displays and then
immediately times out and calls the new URL. While it is waiting for a
response from the server, it is still displaying the Please Wait message,
usually along with a busy cursor. As soon as the new page is returned from
the server, it is displayed in the browser.

Re: Re[2]: Very strange IE problem
I'm sorry, I don't understand your question. If I change the serializer to html, we'd get garbage at best, since the input XML is FO code. We have another page in the application that takes a long time to load because it retrieves a large amount of information from a remote system.

Re: Re[2]: Very strange IE problem
I don't know if this is related, but we have a similar problem with a page
that generates PDFs. The generation take a while, so we have a "please
wait" page that displays and does a refresh to get the generated page when
it is ready. IE won't open the PDF, and gives a strange error message.
This definitely only started happening recently (last six months, maybe?),
and we believe it is due to some security patch or other. However,
changing the security settings for IE to the most permissive doesn't fix

Take a break,I think it probably security probelm for ie6
because of MS system open several property by default,like active-x...,so
it
is easy attacked by virus hacker..
so from ie6 and oe6,MS close lots of unsafety feature,users must open it by
themselves.
so pls try to set the safety of ie6 to lowest,and open all feature closed
by
dedault,then try again.

Re: Passing values into an XSP logic sheet
You can have your logicsheet code read it directly from the sitemap parameters, or for a more general solution pass it in through your template. I assume you are using ESQL? Then you need something like the following: logicsheet: select * from blah where id = XSP: int myID = [code to get parameter value here]; myID .

Re: ESQL update and select statements in the same map:match problem
I don't know anything about the internal workings of the map:aggregate, but I would guess it is not waiting for the first part to complete before opening a connection for the second part. This would make sense, for performance reasons, and there is no particular reason for cocoon to expect the parts to be dependent on each other. So I don't think it is necessarily a bug, nor a caching mechanism, just that map:aggregate doesn't imply sequential processing. Just curious, should the map:aggregate have an "element" attribute specifying the root element for the combined output? Also, what does "strip-root='yes'" do? I couldn't find it in the documentation (http://cocoon.apache.org/2.1/userdocs/concepts/sitemap.html#Aggregating). You could probably make things sequential (and still achieve aggregation) by using either a cinclude transformer, or even more simply by using an XSLT transform step with the document() function, e.g., ... ... with a sitemap like or some such. -Christopher |-+> | | [EMAIL PROTECTED]| | || | | 02/25/2004 01:56 | | | PM | | | Please respond to| | | users| | || |-+> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: ESQL update and select statements in the same map:match problem | >--| hi people i have the folow code : where i call 2 .xsp 1. update_point.xsp where i update a record in my database 2. get_point.xsp where i get the updated record the problem is that this aggregation update the database record (i have check the content) but generate output (get_point) with the before update values is this a caching mechanism case, is it possible to bypass this problem or it's just a bug? --stavros - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: reusing a result set with esql
Adrian, I'm not familiar with RDF, and I can't say I have a clear picture of what you are trying to do, but I think you might be able to do everything you need in XSLT, after the XSP stage. I do a lot of cross-referencing between lists, etc., in an XSLT transform step after generating the raw data from the database. If you want to generate two different bits of output from a single database result, that is even easier. XSLT is very powerful for this type of thing.

When I want to generate the RDF/XML for a list of Partners, the RDF contains : * as many as there are rows (Partners) in the ResultSet. * then an in order to predicate the fact that those entities are part of a list. Every item of the is a _reference_ to the defined entity. Now that you mentioned it I realize that it is possible to not use references but textually include the entities in the .

Re: [once again] best way to set http header encoding
Yes, I agree, the http header should be set, particularly when already providing the content type meta tag. The header is much easier for downstream filters to read and change, if necessary, anyway.

to 4.1.27, and are having no problems. Also, we've just started testing
with Tomcat 5, and it looks like we don't have the problem with it.

allright
If I find the time I'll provide a patch to this, because it is a very
serious problem atm. I was investigating problem and solution already
myself when you posted it to the maillist, because I can't work with the
Apache directive, I will explain why.
The default encoding in the header was added not 'that' long ago[1]. I'm
using Tomcat 4.1.29 now, and it *does* set a default encoding to
ISO-8859-1. So in a way you're lucky you're still using Tomcat 4.1.12,
because with 4.1.29, the apache directive has no effect when connecting
to Tomcat :-) This is why I'm looking for a good solution in Cocoon...
We see and will see this issue more and more, as Bruno mentioned, but
not only because of the browser implementation. In my opinion this is
caused by the changes in this default encoding behaviour when using
Tomcat. The very latest changes should change the behaviour again, so
the upcoming Tomcat 4.1.30 should behave different again. I don't know
what exactly the difference will be, this is wat the changelog for
4.1.30 says:
" Restore the ability to explicitly set the charset to iso-latin-1. Now,
you won't get the charset unless you ask for it (so no more
Content-Type: image/gif; charset=iso-8859-1). However, if you call
response.setCharacterEncoding("iso-9959-1"), you now get it in the
response."
So conclusion:
Somewhere between Tomcat 4.1.12 en 4.1.27 the default encoding behaviour
has changed (my guess is 4.1.17), and there's currently no way in Cocoon
to set the http header encoding so it matches the encoding of the
serializer (and meta tag). Anyone upgrading an old Tomcat will have this
problem, unless using ISO-8859-1. The upcoming Tomcat 4.1.30 should
change the behaviour again, but I'm not sure in what way.

Re: [once again] best way to set http header encoding
there may be no "best way". You can probably fix this issue at several different levels; Cocoon; Tomcat; Apache (if using it), etc. In Cocoon, the easiest would probably be an Action. It can be dirt simple. If you want to use an xsp-action, it could be something like this:
xmlns:xsp="http://apache.org/xsp"
xmlns:action="">"http://apache.org/cocoon/action/1.0">
response.setHeader("Content-Type", "text/html; charset=UTF-8");
sitemap entry (put in the pipeline for each matcher you want to set the encoding for):
type="serverpages" src="">"path-to-action.xml">
It could work.

Subject: [once again] best way to set http header encoding
[SORRY, ONCE AGAIN MY QUESTION, BECAUSE THERE WAS NO ANSWER]
hi there
i wonder that cocoons serializer just writes a meta-tag with the
encoding in the html-page. it doesn't do this in the http-header.
therefore apache set the http-header to his standard-encoding and
"destroys" the correct encoding of the response, because most browsers
ignore the meta-tag if the http-header-encoding is set.
so i need to set the http-header-encoding with cocoon and ask you all,
whats the best way to do this. are there any actions, logicsheets or
something else?
thanks and greetings

Re: Cocoon XSP Documentation : Access to servlet object and core logicsheets
1. The request, context, and I believe the response object are declared and initialized for you, and can be used from any xsp:logic block. The request object is "request", etc. The session object is available from the request (request.getSession()), or is declared as "session" if you use the xsp-session logicsheet. These objects are Cocoon implementations, not the HttpServletRequest, etc. objects (look for Request, Session, etc. in the Cocoon API docs: http://cocoon.apache.org/2.1/apidocs/index.html You can learn a lot about the environment of an XSP program by looking at the class all XSP programs inherit from: XSPGenerator (again, see the API docs). You can also learn a lot by looking at the java source generated from your XSP pages (location varies depending on your servlet engine). I'm not sure where there might be good documentation on these kinds of basics, but perhaps one of the books available on Cocoon would help - just search Amazon for "Cocoon". 2. Some logicsheets are documented on the Cocoon documentation website (http://cocoon.apache.org/2.1/userdocs/xsp/index.html), but many are not. As with so many open source projects, documentation lags until volunteers make up the gap. (I wrote a couple - it was a good way to learn more about XSP and logicsheets.) For logicsheets not documented, your best bet is the source code. In this case, you want to look in your cocoon.jar file for the file "util.xsl", which is just an XSLT stylesheet that defines the elements you can use in your xsp program. Again, there may be better docs somewhere else, such as in a book or on the Cocoon wiki, which I am not so familiar with. Good luck! -Christopher I'm new to Cocoon, I browsed all the documentation distributed with Cocoon but I coundn't find how to access servlet object in XSP page. Question 1 -- how I cae access the various "request", "response", "session", "context" objects in an XSP logic? I couldn't find any official reference and I tried a lot as : ServletContext app = getServletContext(); Question 2 -- Someone knows if there is a documentation to the cocoon included logicsheet library (such as the 'util' used in the examples?, I means a complete API documentation or something like it). thank you in advance, Matteo -- people fall into 10 categories, who knows the binary and who doesn't - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problems with custom taglib
As to your second question, you can't pass parameters dynamically from your xsp program (at runtime), if that's what you're hoping. You are creating an xml structure that your logicsheet can transform into XSP program code. You have all the power of XSLT to work with, but only *before* compilation. Within that, of course, you can create extremely parameterized code; for examples, look at the various cocoon built-in logicsheets. They have a number of standard templates for capturing various "parameters" from the XSP code. -Christopher - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problems with custom taglib
To do a logicsheet, you need to keep in mind that what you are doing is
creating an XSLT stylesheet to transform your code into valid XSP code.
Your template certainly won't do that, because you are mixing class level
logic (function definition) with method level logic (bare call to function)
in the same template. If you use this template inside your page element,
you'll have a function definition inside the generate() method of the final
java code, which obviously won't compile. If you use the template outside
your page element, you'll have a call to "getStr()" at the class level,
outside any function, which obviously won't compile. What you want is a
stylesheet that will put your function in at the class level (e.g., inside
xsp:page, but outside any non-xsp elements), and your call to the function
inside the method. So, try this instead:
http://www.w3.org/1999/XSL/Transform";
xmlns:xsp="http://apache.org/xsp";
xmlns:byteConvert="http://www.beyarecords.com/conversion/byteConvert";
version="1.0">
private static String getStr()
{
String msg = "testing.";
return msg;
}
getStr()
If you want to create the getStr() method only when the
byteConvert:convertByteArrayToImage template is used, then you can wrap the
xsp:logic block in an xsl:if block:

Re: XSP, "for" loop, XSP logicsheets
Are you saying that you want your logicsheet "my-logicsheet:do-with-i" to generate different XSP code depending on the value of i? That isn't possible, to my knowledge. If you just want to have a for-loop calling a template in a logicsheet, that's fine, but the logicsheet's XSLT templates cannot depend on the value of i (that value doesn't exist yet). You can create Java code to do a case statement or a bunch of if-else statements to vary the behavior based on the value of i. -Christopher "Hubert Trzewik \(Prosystel\)" <[EMAIL PROTECTED]> 01/26/2004 01:22 PM Please respond to users To: <[EMAIL PROTECTED]> cc: Subject: XSP, "for" loop, XSP logicsheets Is it possible to do something like this? for (int i=0; i i } The problem is, that I have working logicsheet and I need prepare a fragment tree to be processed by this logicsheet.

Nothing else catches my eye. Here's a couple of things to try: 1) Touch the source XSP (main.xsp) - sometimes logicsheet changes don't get picked up by Cocoon the way they are supposed to after just changing the logicsheet 2) Simplify the problem - strip the code down to the bare minimum to debug, for instance: a) modify your sitemap entry to serialize to XML after doing the server-pages generator step (strip out the XSLT step) b) strip your main.xsp to something like http://apache.org/xsp"; xmlns:abc="http://samspublishing.com/abc/1.0";> 3) look at the generated java source for your XSP page - under your Tomcat work directory good luck! -Christopher |-+> | | "Tommy Smith"| | | <[EMAIL PROTECTED]| | | .com>| | || | | 01/21/2004 10:28 | | | AM | | | Please respond to| | | users| | || |-+> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: Re: Logicsheet not working, anyone help? | >--| Thanks for the reply.

I believe the problem is in your "catch-all" template in your logicsheet: because this is AFTER your template matching abc:datetime, and not at a lower priority, it gets applied instead of your abc:datetime template.

Re: I'm searching for good tutorial about creating XSP logicsheets
Are you familiar with XSLT? (If not, you will not get far making logicsheets!) Just think of an XSLT expression that transforms your XSP to create the XSP code you need. In your example, for instance (assuming foo-value and bar-variable are Java expressions): Result of doing something is Result of doing something else is is a very simple possibility. Result of doing something is Result of doing something else is is better. It's very simple; a logicsheet replaces the logicsheet tags with XSP code. In other words, every logicsheet is an XSLT that transforms an XSP program into another XSP program. Or put yet another way, in each step you are adding more and more xsp namespace code, while removing code in the namespace of the logicsheet. If you get stuck, put your XSP program and your logicsheet through a XSLT transform step (e.g., in XML Spy, or through Xalan), and look at the output. The output should be a correct XSP program. If not, you have a bug. -Christopher |-+--> | | "Hubert Trzewik| | | \(Prosystel\)" | | | <[EMAIL PROTECTED]| | | tel.com.pl>| | | | | | 01/14/2004 12:21 PM| | | Please respond to users| | | | |-+--> >--| | | | To: <[EMAIL PROTECTED]> | | cc: | | Subject: Re: I'm searching for good tutorial about creating XSP logicsheets | >--| I know this tutorial, but it's not enough.

Re: dynamic setting of encoding on serializer?
Thanks - that's a big help, although I may just take the path of least resistance and hand-configure for now :) -Christopher The fact that serializers don't accept parameters and don't have access to the objecmodel has come up before here and is indeed a pain. Can you maybe add a node to the xml using a stylesheet transformer (they do accept parameters), and then filter out this node in the serializer and remove it from the xml before you serialize to the client. Ofcourse for this to work you would need to override at least startdocument, enddocument, startelement and endelement to buffer the xml buildup before you modify it. Admitted, it's a Big Bodge(tm), but it works. Alternatively, there is a patch waiting for the 2.1x branch that is supposed to add parameters for the SVG serializer. Maybe you can have a look how it's done and generalize it to the 2.0.x branch for any serializer.

dynamic setting of encoding on serializer?
Is there any way to dynamically set the encoding of output on a serializer, specifically the XML serializer? I have a customer who is having trouble handing UTF-8 output from my application (he is using Lotus Notes), and would like me to supply a different encoding. I can just create a different serializer with the encoding he wants, but he might need to try more than one to get the desired result, and I don't want to create a thousand serializer entries in my sitemap just so I can handle every possible encoding (okay, I'm exaggerating). I looked at the source (C2.0.x) to see if I could create my own serializer to do this, but there appears to be no easy way; the serializer don't implement SitemapModelComponent, and thus don't get access to any of the usual objects (e.g., parameters, objectModel).

seems like it maybe should be using getNodeValue() instead of

The obvious workaround would seem to be
org.w3c.dom.DocumentFragment fragment =

Thanks a lot, that was the solution, however now I have another problem.
returns not the whole string, I put in the authentication context, but only
the first 7 chars, or so .
For example, when I put "Stephanie Zohner" in the context, only "Stephan"
is
returned.
I looked into the generated Java Code. This is the code fragment, that is
generated out of the Tag.
XSPSessionFwHelper.getXML(this.manager,
String.valueOf("authentication"),
String.valueOf("/authentication/data/name"))).getFirstChild().getNodeValue())
);
It takes only the first child node of the returned XML Fragment. However
"Stephanie Zohner" is shared among 3 child nodes.Taking only the first node
results in extracting only the first of three parts of my name.
This happens when I use the "as= 'string'". If I use "as= 'object'" I would
get the entire string, but then again I get an eeption (as you have
predicted), because a String is expected by the my method and not an
DocumentFragment.
Is it a bug, that only the first node is taken when using the attribute
''as
= 'string''?
Are there any work arounds?
Thanks in advance,
Stephanie

try instead. That should copy the into the output, where it will later get turned into some kind of java expression (hopefully!) by the xsp-session-fw logicsheet.

Re: FW: Escaping in XSP Logic
I am not a Java expert! My guess, it looks like an encoding problem, perhaps due to your XML editor, or some oddity within the Cocoon pipeline. I tried this in my environment (C2.1, Tomcat, using Eclipse+Sunbow for coding) and it worked fine when I set the XSP source encoding to iso-8859-1. When I used UTF-8 encoding and the entity reference ç it worked fine. When I used UTF-8 encoding and put the ç directly in the code, I got a Cocoon processing exception (java.io.UTFDataFormatException): "Invalid byte 2 of 3-byte UTF-8 sequence". So my guess is that the Sunbow editor saved the code wrong for the encoding my XML is supposed to be using. Probably your best bet is to change your source file encoding to UTF-8, and use the entity reference. -Christopher |-+---> | | "Yves Vindevogel" | | | <[EMAIL PROTECTED]| | | lements.be> | | | | | | 12/04/2003 04:30 PM | | | Please respond to | | | users | | | | |-+---> >--| | | | To: <[EMAIL PROTECTED]> | | cc: | | Subject: FW: Escaping in XSP Logic | >--| nobody ? -Original Message- From: Yves Vindevogel [mailto:[EMAIL PROTECTED] Sent: woensdag 3 december 2003 19:21 To: [EMAIL PROTECTED] Subject: Escaping in XSP Logic Hi, I have this syntax ...

Hi all,
I'm making a little project in cocoon and I have been cornered now (nothing
unusal :)). I need to implement
a permission control of user's actions (it means, that for example some
users
can create something, another users can just read somehing etc.). All is
ok,
but I don't know, how to
check user's permissions in XSP. My idea is to write something as:
if ( == true) {
... then do something, what are you allowed to (some XSP, calling another
logicsheets etc.)...
}
or something like that:
... then do anything, what are you able to...
The namespace "permission" is defined by a logicsheet, for example
template "check" will look into SQL databaese, if the appropriate user has
appropriate permission "user_can_write".
I think, that it is relatively usual stuff and many of you have to write it
almost every day... But when I tried to make it, following problems
encountered:
In the first case is a problem, that if template looks
into
db thru ESQL, it creates tons of java code, so it is no possible to compare
with value as a normal variable, of course.
In the second example I solve a problem, how to copy the inner content of
template without changes to be consequently correctly evaluate by another
logicsheets (my own other logicsheets, xsp logicsheet etc.) and virtual
machine.
Another possibility is to write a pure java class, it will look into db and
will be return corresponding information. But how to use a connection pool
of
cocoon (and if possible without settings of concrete connection parameters,
that are stored in the cocoon configuration file)? Don't you know a link to
concrete examples? In user docs are just very general and non-concrete
informations.
What am I doing wrong, please? Or do you have another idea, how to solve my
problem or some existing solution? Thanks a lot!

You can't do String equality this way in Java. Try this instead:

The = for Strings is an Object identity test, not a value comparison test.

XSP with multiple logicsheet compilation errors
Sorry for the cross-posting; I wasn't sure who would best be able to
answer. We are using C2.0.3 on Tomcat 4.1. If it is relevant, the problem
most frequently happens on our servers which are Solaris 8, Apache 1.3.x,
mod_jk.
We keep having a problem occasionally in which logicsheets are not properly
applied to our XSP's, resulting in uncompilable code. We so far cannot
reproduce the problem reliably. It usually happens at the worst possible
time (e.g., when we have just deployed new software to production, or
during a demo). Sometimes the problem can be fixed by stopping and
restarting the web application. Sometimes the problem can be fixed by
mucking with the XSP source code, although I haven't found any reliable way
to fix it.
We make heavy use of logicsheets, and our logicsheets use other
logicsheets, and so forth so that there is often quite a long chain of
logicsheets that must be applied to generate our source, and I'm sure that
contributes to the problem. However, the intermittent nature of the
problem leads me to believe that it is a "bug" or at least shortcoming in
the XSP generation code. A typical symptom of the problem is that some
page will not compile, and when we go to look at the source code, the
source has not transformed tags for one or more logicsheets (often ESQL).
Instead, java code is generated that attempts to output the logicsheet
tags. So, for instance, if you have code like:
if ( == -1) { }
it turns into:
if (
this.contentHandler.startElement(
"",
"esql:get-int",
"esql:get-int",
xspAttr
);
...
)
or something like that, and you can see why it wouldn't compile!
Note that these pages do compile most times, so it isn't due to missing
namespace declarations or anything like that. The problem doesn't appear
to be due to any problems with our code - the same webapp code that
compiled and ran fine on our workstation or on a test server will suddenly
compile wrong on the production server, then fix itself as soon as we
restart tomcat. Also, we have seen this happen both with the built-in esql
logicsheet as well as our own logicsheets.
Our best theory at this point (and it is only a theory - we don't know
where in the code to even begin looking for this) is that when an
uncompiled page is called twice quickly (as might happen on a production
server), the two calls interfere with some shared queue or some such which
informs the XSP generator which logicsheets to apply, and in which order.
In other words, some shared structure which is not properly protected for a
multi-threaded environment. The best evidence in favor of this theory, I
think, is the fact that the bug doesn't happen regularly (say 1 time in 10
deployments), even on the exact same code.
Anyway, does anyone have any ideas about this? I searched the archives and
found nothing, but is this perhaps a known issue? Is it fixed in a newer
version of Cocoon? (We do plan to move to C2.1, but have higher priorities
right now; and since we can't reproduce the problem reliably, we can't
quickly test "just to see" right now.) Can someone who has worked on the
XSP generation code contact me and perhaps suggest some classes to look at,
which control the application of logicsheets to the XSP source? Any help
greatly appreciated.

Re: XSP and looping elements
This should work fine, although you may need to put around your

You could also put the for loop around your node.

Ok, this works, but, What if I want to loop ESQL-commands?
x
for (int i = 0; i < 10; i++) {
SELECT NEXTVAL('list_id_seq') as id
}
Will make:
http://apache.org/cocoon/XSPDoc/v1";
xmlns:esql="http://apache.org/cocoon/SQL/v2";
xmlns:xsp="http://apache.org/xsp";>
x
for (int i = 0; i < 10; i++) {
And no SELECT-clauses to SQL-server..
So, howto loop SELECT-clause?

Re: Dynamic parameter for logicsheet
My previous answer was lacking in several respects. Here is a better one: you are expecting your query to end up with "id = 5", but that won't happen because your logicsheet is applied *before* the XSP is even turned into Java code. So there is no possible way that your logicsheet could obtain the value "5" from the java variable and do the substitution as you are expecting.

Re: Recursive reading from database
No, your functions must be defined within an xsp:logic block, which will protect them from being the top user element in xsp:page. The output won't occur until you call the function, which will be within your top user element. So you should be able to get the output you are expecting. I have had problems in the past doing output from user functions, due to some xspAttr variable or some such not being available. It seems to me that it was easy enough to fix, by passing the missing variable into the function call. If that won't work, you can always fall back on building a list in Java via recursion, and returning that from your function. Loop on the list in your main body to output. But you should be able to do output from your functions, with a little work. -Christopher Otmar Vobejda <[EMAIL PROTECTED]>To: [EMAIL PROTECTED] cc: 11/05/2003 03:48 Subject: Re: Recursive reading from database PM Please respond to users Thanx for your answer.

Re: Recursive reading from database
ESQL elements don't have to be inside the top user element, at least in
C2.0. We use ESQL in user-defined functions all the time. This wasn't the
case in C1, as it used local variables in the generate() method, but now
all its variables are declared at the object level, and just initialized in
the generate() method.
I take it you are using a database other than Oracle? Oracle provides
support for this kind of tree relationship in SQL (using the CONNECT BY
clause).

Hi, i'm a beginner in the Cocoon domain and first problem, what I'd like
to solve, is recursive reading from database. For example you have a
table test(id int, parent int, name varchar), where parent attribute
points to id attribute of parent rows and you need to read all the rows
to the tree.
for example something like this (excuse the syntax :):
// recursive function
public void readData (int parent) {
select id, name from test where parent= $parent;
for each result {
print ($name);
readData($id);
}
// start recursion:
readData(null);
But how to write in XSP, when methods need to be in root
element and esql tags must be inside top user element (or how it is
termed).
Thank a lot for each your outline!

Re: XSP/ESQL escaping
Yes, it is a pain, isn't it? XML just doesn't care to know about or deal with whitespace, and that really is a pain when whitespace IS content!
To answer your question, it depends. If you just have a string (no XML markup in the database), then something like this is the easiest:
String instring = ;
java.util.StringTokenizer st = new java.util.StringTokenizer(instring, "\n", true);
while (st.hasMoreTokens()) {
String token = st.nextToken();
if ("\n".equals(token)) {
} else {
token
}
}
If what is in your database contains XML markup, you'll need to do something more like this (mostly lifted from the ESQL logicsheet):
String instring = ;
instring.replaceAll("\n", ">br/>");
org.apache.cocoon.components.parser.Parser newParser = null;
try {
newParser = (org.apache.cocoon.components.parser.Parser)
this.manager.lookup(org.apache.cocoon.components.parser.Parser.ROLE);
InputSource __is = new InputSource(new StringReader(rawXML));
XSPUtil.include(__is, this.contentHandler, newParser);
} catch (Exception e) {
getLogger().error("Could not include page", e);
} finally {
if (newParser != null) this.manager.release((Component) newParser);
}

Re: XSP/ESQL escaping
Yes, you cannot use tags inside java strings in this fashion. When XSP
sees this tag, it tries to insert a whole block of code to output the tag
into the SAX output, which should give you a compilation error.
I'm actually not certain how it is you are able to pass the results of
esql:get-xml into a function call without getting compilation errors. The
get-xml tag also turns into a whole block of code, not an expression which
can be passed to a function. What version of Cocoon are you using? In
C2.0.3, which I am using, you would be unable to do this, and you would be
unable to do substitutions inside the returned XML. Instead, you'd have to
get the results using get-string, do your substitutions (using < in
place of <), then run the resulting String through an XML parser to get it
into the SAX stream. (A good example of this is the code that implements
get-xml in the ESQL logicsheet, which is in your cocoon jar file.)
HTH.

Thanks for your time
The formatMessage is implemented above the problem in the xsp logic
section, and it (currently) only does this :
public string formatMessage(String message)
{
return instring.replaceAll("\n", ")
}
the problem area in the xsp, like I said looks like this
formatMessage()
The problem occurs when the xsp:expr contains tags (i.e. if I do the
replace "\n" ---> "foo" , then all is well, but "\n" ---> "" will
not work. )

Re: XSP/ESQL escaping
Where and how is formatMessage() implemented? That is the code we really need to see, I think. We also use eclipse+tomcat 4+cocoon 2.0.x. For some classes of error (I'm not sure which ones), Eclipse suspends the thread for debugging, which might be causing the timeout you are experiencing. If you don't get a response in the expected time, go to the debug perspective and continue and suspended threads. That will produce the normal Cocoon error message page in your browser. (There might be a way of telling eclipse to ignore those exceptions, I haven't explored it.) -Christopher |-+> | | Anders Forsgren | | | <[EMAIL PROTECTED]| | | rmers.com> | | || | | 11/04/2003 02:41 | | | PM | | | Please respond to| | | users| | || |-+> >--| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: XSP/ESQL escaping | >--| Hi I have a problem with escaping when retrieving database data in an xsp page.

Re: ESQL problem
Your code looks correct to me, I can't imagine why there'd be a problem.
I've never used (or even heard of) a pervasive database, but if you can
write JDBC code that works against it, it ought to work in ESQL.
Is your pool set up correctly? Do you log in with the same user as in your
separate JDBC test? Can you tell from the generated java source if it is
following the same steps you do in your own JDBC?
If you put code in an block after the
block, does that execute?
Just out of curiosity, what does the
pervasive line do?

I have encountered something strange concerning ESQL. I am using Pervasive
database. This is a ESQL code snippet:
symfonia
pervasive
select * from xt where kod like '%ń%'
String test = ;
getLogger().error( test );
If you have a strange character in select statement - that's OK - it's a
polish letter.
The problem is: the query does not output any data.
The same written in JDBC (off cocoon):
PreparedStatement stmt = conn.prepareStatement("select * from xt where kod
like '%ń%'");
stmt.execute();
ResultSet rs = stmt.getResultSet();
while ( rs.next() ) {
System.out.println( rs.getString( "kod" ) );
}
works just fine.
I have checked the xsp java generated source - the polish letter is
encoding
using the same byte value so I do not get it what makes the difference.
Comments anyone ?

Re: Weird logicsheet problem
well, now that I look at it, I would expect this to fail. Again, look at
where you are putting this code: at the class level. The String array
filelist is being created at object instantiation time. The contextualize
function is almost certainly not being called until *after* the filelist
variable is created and initialized. Are you very familiar with java?
Looking at the generated source code should help you with this kind of
problem.
Instead of creating a variable to hold on to your file list, why not
instead create a function that you can then call whenever you need the
filelist. That will avoid your timing issues, I think.
String [] getFilelist() { return uploadDir.list(); }

Hi.
this piece posted works almost fine:
org.apache.cocoon.components.language.markup.xsp.XSPUtil
org.apache.avalon.framework.context.ContextException
public void contextualize(Context
context) throws ContextException (
uploadDir = (File)
context.get(Contstants.CONTEXT_UPLOAD_DIR);
}
String[] filelist =
uploadDir.list();
The only problem: It always gives a nullpointer-exception, because the
"uploadDir.list()" is empty (for some stupid reason).
In my xsp's this code works fine. It gets all the names of the
files(+directories) of the upload-directory I specified in the web.xml file
(and in my case this directory isn't empty).
