public abstract Boolean isQuery()
Hi all Just trying to clarify my understanding. I had some code that looked like the following: @Persist public abstract Boolean isQuery(); The above code gives me an error, 'no implementation in class', and it took me a while but I finally figured the problem that the enhanced class was not identifying the Boolean. It took a while longer for me to realise it was because I didn't have a valid 'getter'. I had to change the above to: @Persist public abstract Boolean getQuery(); Suddenly everything started working! So, why doesn't the enhanced class identify these boolean style function names. I thought this was some standard that ALL property functions were fetched using get* and ALL boolean values fetched using is*. Question: 1. Should I code all of my booleans using get* in future? 2. How does OGNL now deal with a boolean value returned via a get*? Do I need to modify my OGNL conditions?

Re: Record locking
Wow - what a lot of responses. First a little more detail - use case (for example): Take a customer record, a basic record has previously been created and the customer has completed some forms so we are now wanting to complete all of the details about contact information, financial details, key assets, health information, etc, etc. The system relies on a number of classifications which need to be looked up, anyways, editing this record can take upto 20 minutes. The size of this record certainly justifies breaking it up into a number of smaller records stored in separate tables, however the same problem remains because the user wants to see all of this information on 1 (scrollable) web page, we are still holding a lock on the information for the duration of the request. Potentially there are maybe 700 people who could be editing this record for different reasons. Accuracy of the information is critical - we don't want personal details being sent to a neighbour. The nature of the application means that users will be reviewing a record each year, and if any changes are made they are often made to the same record around the same time of the year - increasing the possibility of two people wanting to edit the record at the same time. Besides all of the above, the user has asked for exclusive editing of a record - such that other users can still read the existing record but nobody else can update the record while it is locked. The user understands the concept of networks issues and broken connections and therefore accepts a timeout condition on the lock of say 20 minutes. Next, how I will do this: 1. To establish a lock: a. I need a LOCK table: foreign-key, timestamp, userid b. In my Session I need a collection of timestamps c. Create a timestamp value - add it to my collection of timestamps d. Add a record to the LOCK table using my timestamp value e. Select from the lock table by foreign-key - if mine is the only record then read the record and begin editing, the lock was successful 2. Release the lock: (PS This is the difficult bit) a. Retrieve the LOCK records by foreign-key and userid, hopefully there should only be one. b. Check the timestamp value against my Session collection of timestamp values c. If the timestamp is in my collection then save the edited record and delete my LOCK record d. If the timestamp is not in my collection then the save has failed - tell the user gently 3. Dealing with an existing lock: a. While trying to establish a lock I find 2 LOCK records b. The latest record is mine, ignore that and look at the earlier record c. Look at the timestamp on the earlier record, if older than 20 minutes then delete this record and continue as normal d. Look at the userid on the earlier record, if it is mine then delete it and continue as normal (assumes my browser died, rebooted my computer, whatever, it's very typical for people to go straight back to what they were doing when their system crashed) e. If the timestamp is less than 20 minutes old then delete my LOCK record and report to the user that the record is locked by another user 4. You may want a maintenance process that cleans up broken locks, automatically deleting locks with a timestamp older than 24 hours. You could schedule this nightly or weekly - it's not critical. Why the collection of timestamps? 1. It allows the user to use the back button on the browser, either during editing or after editing (if it didn't save correctly the first time). 2. They might need to edit a related record in a different table as part of updating the main record - by storing each timestamp in a session collection we don't need to maintain these timestamps on our forms. Why add the lock record first? To avoid sequence problems like: a: User 1 looks for lock on id=1 - none found b: User 2 looks for lock on id=1 - none found c: User 1 adds a lock record d: user 2 adds a lock record Now the worst possible outcome is: a: User 1 adds a lock record on id=1 b: User 2 adds a lock record on id=1 c: Both users read and find two records with short timestamps - they are both informed the record is in use and to try again later - both records are deleted. Finally - the weakness: 1. The lock this gives you is only guaranteed for 20 minutes. Once that time is up somebody else can overwrite your lock with their own. It is better to set this timeout higher rather than lower. 2. You can overwrite your own lock. A user could open two browsers and edit the same record in each, the latter save overwriting the first. Hmmm, I think this comes under 'user error'. I think that explains it fairly well. Cheers mc - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Record locking
James Carman james at carmanconsulting.com writes: You can use optimistic locking. When the user submits and they have outdated data, then you just merge the object's data with what is in the data store and show it back to the user for them to confirm it. In an application where the user can spend 20 minutes completing the information in a row, they are not going to be happy when they find out somebody else has been updating this same row and the information has all been merged. They then spend another 10 minutes cleaning up all of the duplicated changes. Even pessimistic locking is not sufficient. I need guaranteed write-exclusive locking for the duration of the request. ie when I read-for-update the record should be locked against all other read-for-update requests until I save my changes and release the lock.

Record locking
Hi all Many years ago I wrote a web application that utilitised a proprietary database. The database supported record locking however it was not suitable for a web application. So, I wrote a facility I called 'Long Locks'. It required a timestamp field be added to each table. When a web user wanted to edit a record they would check if the timestamp field was null, if so they wrote a timestamp into the record and sent this along with the data to the user (the timestamp was not visible by the user). After they had completed updating the details (which could take upto 20 minutes) they could then save the record, the timestamp would be compared with the entry on the record and if they matched the update would be committed. This enabled a number of key features: 1. I was able to guarantee write access for a user when they requested a record for update. (If the record was already long-locked I would inform the user the record was locked by another user). 2. I was always able to read the record 3. If a user abandoned a long-locked record the lock would eventually expire (we set this to 20 minutes for our application) I have been reading through a number of record-locking strategies but it seems most of them are optimistic in that they hope nobody else has updated the record since it was read, and in the event that it was all of your changes are lost. This is very frustrating for the user has just spent 20 minutes entering data! I'm happy to write my own locking system again. I was just wondering if anybody knew of a better way - something to save me writing my own system again?

Re: Example tapestry 4.1 with ajax style calls
Hi guys
Great responses - both were exactly right.
However both lacked any reference to a simple example to get Ajax calls working
in Tapestry 4.1. If anybody has one I'd be keen to see it?
I have watched this list long enough to know it is possible yet as much as I try
I'm still not getting the page portion updating - and worse, there are no
obvious errors happening either.
I'm using Firefox/Firebug which is really helpful:
I'm sending:
GET http://localhost:8080/cabs/order/Main,$DirectLink_1.sdirect?
sp=S3updateParts=orderareabeventtarget.id=DirectLink_1
beventname=onClickdojo.preventCache=1171662192656
And being returned is:
ajax-response/ajax-response
As background, this is supposedly creating a tab style page, and when a tab is
clicked the area inside div id='orderarea'the tabs area included in here along
with the main tab area/div should be updated.
So, I'm going to assume my html is correct, however just for the record:
div id='orderarea'
...
a jwcid=@DirectLink listener=listener:changeTab
parameters=4 async='true' class=tab
span jwcid='@Insert' value='ognl:getTabtext(4)'Dates/span
/a
...
/div
Most of the action happens in the java file associated with this page:
public abstract class Main {
private static final String tabtext[] = {
Customer,
Style,
Components,
Dates };
public String getTabtext(Integer ix) {
return tabtext[ix.intValue()-1];
}
public void changeTab(IRequestCycle cycle) {
Object[] parameters = cycle.getListenerParameters();
Integer iix = new Integer((String) parameters[0]);
setCurrentTab(iix);
System.err.println(Set tab to + iix.intValue());
cycle.getResponseBuilder().updateComponent(orderarea);
System.err.println(Requested update to 'orderarea');
}
public abstract Integer getCurrentTab();
public abstract void setCurrentTab(Integer ct);
// Plus some other stuff which is irrelevant
}
Is there something I'm missing here? All of the log messages appear as expected
when I click the tab, so I know it's running, there's just no content coming
back in the response.
Cheers

Re: My crap development environment
Hi all Does anybody else find this hellishly confusing? It makes me want to throw everything out and go back to a nice simple DOS system and a Turbo C compiler! How much simpler it was back then... Okay, I downloaded the latest Eclipse system, copied my project into a fresh workspace. Saving a file was back to a sub-second response. Actually I tried saving a second file to make sure it wasn't a fluke the first time. There was definitely a problem somewhere and it has now gone away. Okay, now the second part of the problem. Tomcat or Jetty??? I don't want to package every time I make a small change to a config file or HTML, so I want the servlet engine to use my files from my development area. My previous frustrations with restarting tomcat have encouraged me down the Jetty track - I downloaded Jetty 6 yesterday and the test system was working in about 5 minutes, pretty good. I then added a context.xml for my application and now when I start Jetty it simple crashes and refuses to start the application. I get an error like: 'No class for Servlet or Filter' I haven't been able to find any help on this error. I did find information on a Jetty-Maven-Plugin but form my reading this is all about packaging the application - I don't want to go there. I also found a number of recent comments about Maven2 saying it was still quite buggy. Do I press ahead trying to solve the Jetty stuff or do I revert back to a Tomcat system??? I'm developing in a Windows XP environment so this may limit me from some of the options suggested here.

Tapestry 4.1 startup errors

I'm getting really frustrated with Eclipse. I started by adding a user library called Tapestry411 and placing all of the JARs in this user library. Eclipse would say that it was publishing the application but the user library was never copied over. So, I moved all of the jars to the WEB-INF/lib folder in my development area, however Eclipse doesn't recognise the WEB-INF/lib folder as a library of jars and so it reports all of these errors that it can't find classes. So I left all of the jars in the WEB-INF/lib folder in my dev area and created a user library that located the jars in the WEB-INF/lib folder (I feel like I'm jumping through hoops because Eclipse isn't working like it should). Finally I publish the application and everything gets copied except for the jars. I start tearing my hair out at this point. In utter frustration I then manually copy all of the jars into the WEB-INF/lib folder of the server. The server now starts up without any obvious errors. When I try to use the application the above error occurs (before the first screen is displayed).

My crap development environment
Hi all I have suffered long and hard under Eclipse and Tomcat. Is it really necessary for me to wait so long while a file is saved or an application is published??? Saving a .java file: 15 seconds Saving a .html file: 15 seconds Saving a .jwc file: 28 seconds Stopping the tomcat server: 2 seconds (acceptable) Publishing to the tomcat server: 45 seconds Starting the tomcat server: 54 seconds (it insists on publishing first) Does everybody else experience these delays or is it just me? It was suggested that I use maven2 - however I looked through the maven2 flash presentation and it didn't mention anything about making my development work in Eclipse faster - it was more focused on pulling dependencies and easing the build process.

Example tapestry 4.1 with ajax style calls
Hi all
I hunted for ages and haven't been able to find any simple examples of how to
use the Ajax features of Tapestry 4.1. Sorry guys, it's just not obvious from
the documentation how it works.
You would think a basic @DirectLink with updateComponents and async=true would
do it - nah, didn't work for me:
a jwcid=@DirectLink listener=listener:changeTab
parameters=2
updateComponents=orderarea
async='true'
class=tab
Text/a
public void changeTab(IRequestCycle cycle) {
Object[] parameters = cycle.getListenerParameters();
Integer iix = (Integer) parameters[0];
setCurrentTab(iix);
System.err.println(Set tab to + iix.intValue());
}
The page displays but when I click the above link it disappears and I see part
of an exception output display.
If somebody can point me at a simple Ajax enabled app using Tap 4.1 would
probably help me greatly.

What's with the library directory structure?
Hi all
I'm in the midst of upgrading from Tap 4.0 to 4.1.
I downloaded the Tapestry 4.1 binaries, however what I found was a directory
called 'modules' with subdirectories for a whole bunch of things like,
'backport-util-concurrent', 'commons-beanutils', 'hivemind', 'hivemind-lib', etc
etc. I'm sure you know what I'm talking about. Every Jar is in a different
sub-directory.
My question is, why is the distribution split up this way? Aren't we all simply
copying them into a single directory ('WEB-INF/lib')? Is there some purpose to
this directory structure that I'm not aware of???

IPropertySelectionModel - what they don't write in the documentation
Hello tapestry experts
The API documentation for IPropertySelectionModel is lacking key information.
In particular how the initial value is defined.
What it should say is stuff like:
To set the initial value of the HTML select element you need to bind a value to
this control. The type of value bound is important [This is where somebody
else needs to take over.]
I have spent all day trying to initialise a value in my HTML select element. I
had searched through the lists and the web but I didn't find anything like what
I was experiencing. Check out this:
I had a static list of security levels:
private static final String[] textOptions = new String[]{
(none),
Quoting,
Ordering,
Shop manager,
Manages all shops,
Office staff,
Administrator
};
and some standard functions in my selection model:
public int getOptionCount() {
return textOptions.length;
}
public Object getOption(int index) {
return new Integer(index);
}
public String getLabel(int index) {
return textOptions[index];
}
public String getValue(int index) {
return String.valueOf(index);
}
public Object translateValue(String value){
return Integer.parseInt(value);
}
and very normal stuff in my .page file:
component id=securityField type=PropertySelection
binding name=model value=bean:securitySelectionModel/
binding name=value value=user.security/
/component
bean name=securitySelectionModel class=SecuritySelectionModel/
All of this I had done before and everywhere else it was working fine. But
suddenly this one didn't work. Then it occured to me, maybe the value from
user.security wasn't being passed correctly.
public void setSecurity(short security) {
this.security = security;
}
public short getSecurity() {
return security;
}
It's a short! Okay, so how does that affect setting the initial value for my
select. I read through the documentation over and again, search the lists,
absolutely nothing. It shouldn't affect it. My other examples were of type
'int' and my guess is that Tapestry would cope with translating a short to an
int - not a chance. I tried adapting the translateValue() function to return
Short.parseShort(value) but this still didn't work. What else am I supposed to
change???
It appears that IPropertySelectionModel only works with integer values! I
finally made a work around that looks like this:
binding name=value value=user.securityint/
and
public int getSecurityint() {
return (int) security;
}
public void setSecurityint(int sec) {
this.security = (short) sec;
}
How sad is that!
Okay, what should I have done?
Cheers

Re: Contrib:Table problems with layout
This sounds like an HTML issue. Tapestry components are added into standard HTML, they do not generate any different HTML than you have already specified. For example, you say the contribTable appears at the right of the page, perhaps you are specifying widths on your static tables - maybe you need to add the width parameter to your contribTable.

RE: Streaming files from Tapestry
Hi Ezra I did look at doing this as a work around, however it has one major flaw - it doesn't provide any security. In a CRM system, for example, if the document download link is http://webserver/MyOtherWebContext/images/01.doc then it's not going to take somebody long to realise they can type in other numbers and retrieve documents that they may not have access to. With a servlet running inside my application I can check the users security immediately before I stream the document. The other benefit of keeping the servlet as part of my application is that I can store the external directory name in one location rather than two. A small benefit. My final argument is that the faq should be providing the recommended solution. Obviously lots of people have already asked for this (that's why it's in a faq) so I'm not alone out here... I have written a small servlet to do what I want. It has limited functionality but it serves my immediate purpose. I am still hopeful that somebody will deliver a servlet or library that does serve this purpose in a better and generic method, I am happy to be the first to test and implement it. Cheers mc On 28 Jul 2006 at 9:53, Epstein, Ezra wrote: I'm not sure I really followed, but your option c doesn't seem to have anything to do with a web framework (tapestry or otherwise). Rather you're just dynamically generating some text a la: img src=/MyOtherWebContext/images/my-dynamically-named-image.gif / Or whatever. The only part of that which is dynamic is the image name. And Any tag can give you this no sweat. Maybe the name of the other web context is a config param and so is dynamic too. Again, no sweat. As for the serving of the static files themselves (the name of a given file is dynamic in that if you're showing the details of a CD then the image name may depend on the product, but the image itself is in a web servers file system) any web server will do. Apache, Tomcat, JBoss, etc. I think the problem is with the word stream. Stream implies dynamically feeding data into the response. I think your question is about serving images. If so, it's a snap. For example, I serve my Tapestry javascript files (same applies to images) simply as: script type=text/javascript src=/MyTapestryAppName/js/myJavaScriptFile.js/script Works great.

The example that follows works for a 'Document' type which is fine, however the 'disowner' at the bottom of the answer indicates that this is not the way this should be done. Also, recently in the forum when somebody tried this they found it only worked if you were sending this document as the only result (not as an image or other object type in the midst of a page). So, can somebody please document the answer to this question how it should be done? And of course - update the faq.

Also, recently in the forum when somebody tried this they found it only worked if you were sending this document as the only result (not as an image or other object type in the midst of a page). So, can somebody please document the answer to this question how it should be done? And of course - update the faq.

RE: Overriding the maximum file upload size
Hi Ben The change made to the documentation: From: implementation service-id=tapestry.multipart.MultipartDecoder To: implementation service-id=tapestry.multipart.ServletMultipartDecoder solves the problem. Specifying MultipartDecoder was generating some initialisation error - Tapestry simply wouldn't load. I'm glad the limit is 10mb - that seems very reasonable as a default.

Overriding the maximum file upload size
Hi all I am using Tapestry 4.0.2 In the documentation on the 'Upload' component it mentions a default upload size of 10,000,000 (10 million) and in brackets 10kb. I'm not sure how that works. Which is correct? Assuming all my worst nightmares are coming true and that the limit is 10kb (although I would much prefer a 10mb default limit) I went blindly ahead and added the multipartdecoder stuff to my hivemodule.xml file. Alas it fails miserably. All is not lost though as I found a bug had been reported and fixed as documented here... http://issues.apache.org/jira/browse/TAPESTRY-995?page=all Well, the bug is fixed for Tapestry 4.1 but there is little detail about what the problem was and whether it can be avoided in 4.0.2. While I am new to Tapestry I am not new to the huge number of issues that can result in trying to upgrade one library in an application. 1. Is there a way of avoiding this bug in 4.0.2? 2. Is the default limit 10kb or 10mb? PS Can the documentation be corrected for this please?

Generic application wide formats
Hi all I'm a little new to Tapestry so I may be missing something, happy for anybody to point me in the right direction. I'm currently running Tapestry 4.0.2 I want to standardise my date format for the entire application to dd/MM/. I decided that the best place to do this while allowing for internationalisation is to add it to my app.properties file. I added a few other formats while I was there, so I had something like the following: # Generic formats format_date=dd/MM/ format_time=HH:mm format_pct0=##0% format_pct2=##0.##% format_currency=$#,###,##0.00 Then I found that in order to display a date in this format I was writing 7 lines of java code for each page where a date was displayed (most of them)...along with 1 more line in the .page file for each date to be displayed. When I wanted to edit a date again using this format I had 4 lines per page and 1 line per field. This only provides the most basic of editing (I haven't allowed for any error processing yet) and while the number of lines is not large it did seem to me that there were different methods being employed to format the date for display and others for edit and validation. As I began, I may have missed something but it does seem a little messy at the moment. Does anybody have a better method of achieving this generic formating?

Dump Krysalis and use JS Cook Menu. It is much easier to customise and also allows better integration with your java code for generation.

RE: Re: Generic application wide formats
What you have suggested is in fact what I am already doing for the date entry /
update. I'm
also having to use a special method in my .java file to retrieve the format
whenever I want to
display a date in this format.
My problem is that this is a significant amount of coding required on each page
for something
that should be generic across my app. Do you agree?

Re: Table foreach component - Flashing row
What's the problem? You can test your condition at the beginning of the row, when writing the tr component, so that you generate something like tr style=background-color: red; or tr class=rowinerror I'm sure you've got past this. You mention when certain text is received, does this mean from user input in the midst of the table row or from the database? Are you able to test the condition at the beginning of the row. If you can't test at the beginning you could get JS to modify the background colour of the row, all you need is to assign an 'id' to the row and then retrieve the row in your JS and start changing properties. Maybe you've tries this too... One last thing, are you setting background colours in each cell? If you do these will overwrite the background colour of the row in which case you may need to use JS to obtain control over each cell and set the background colour property manually in each.

And I'm not going to say HTH as I know it will.

PS I'm sure there is another way to do this using a bean but the above does
make sense in
Tapestry and you not only get the even/odd thing, you also get a row counter.
PPS The other bit I did was to move the content of the getRowStyle() method to
an
application class, I'm going to use this on lots of pages and if I change the
names of the
even/odd styles I want to do this in one place and not 50. So it became:
public String getRowStyle() {
return SomeApplicationClass.getRowStyle(rowIndex);
}

Re: alternate row colours in foreach
HI Peter The HTML needs to be almost identical to mineyou will notice in my span there is a parameter called: element=tr this is the trick that adds the style stuff to the 'tr' tag during rendering. Sounds like you need to remove your 'tr' tag and live with my 'span' tag. Also, if it's still not working, post your html file.

Re: Running the Tapestry Tutorial
Hi folks I have updated the INFO.txt file that is downloaded with the tapestry-tutorial - would somebody like to review and update this back into the zip file, it may help somebody else following me... Cheers mc-- Murray CollingwoodFocus Computingp +61 415 24 26 24http://www.focus-computing.com.au tapestry-libraries.tar.gz Ccontains just the Tapestry libraries, including all the current dependencies. tapestry-tutorials.tar.gz Contains the libraries as well as all of the Tapestry QuickStart tutorials. The QuickStart Tutorials are distributed as a set of Eclipse workspaces (though Ant build files are supplied as well). They depend on an Eclipse User Library to locate the libraries. You can create a User Library as follows: - Select Window - Preferences... from the menu - Navigate to Java / Build Path / User Libraries - Click New - Name the library Tapestry Libraries - Click Add Jars ... - Add all the JAR files in the tapestry-libraries/lib/web folder To build the tutorials you needs ensure you are running JDK v5.0 (comes after v1.4). Extract the downloaded files to a new directory, eg C:\TapestryTutorials. Don't extract it into your existing workspace. From Eclipse select File | Import... 'Existing projects into workspace', click the 'Browse' button to select a root directory, select the directory you extracted your download to. In my case above I selected C:\TapestryTutorials. The import projects dialog should display all of the projects that can be imported, these include 'directlink', 'forms', and 'helloworld' (depending on the version of the tutorials you have downloaded). To build the projects you have imported you should find a 'build.xml' file inside each project. Right mouse on the 'build.xml' and select 'Run As' | 'Ant Build'. Problems: The most likely problem is an issue compiling the project due to errors with the annotations, eg @Persist. If this is the problem then you need to find why your system is not using the JDK v5.0 libraries. It may still be referencing an older version somewhere. Check through the Windows | Preferences, the project properties (right mouse on the project), and the Ant build properties (right mouse on the 'build.xml' and select Run As | Ant Build...). tapestry-examples-xxx.tar.gz A prebuilt JBoss distribution, containing the Tapestry Workbench and Virtual Library applications. Unpack the distribution, change the bin directory, and use the run.bat or run.sh script to start up JBoss and the examples.

Where are the Australian supporters?
Hi all I looked through Tapestry Support Network page but couldn't find anybody in Australia (preferably Brisbane). I'm just starting out on my first Tapestry project and need to ensure I'm making some educated choices about how it is structured and also getting my environment setup correctly. Is there anybody on this list from Brisbane that would like to give me some one-on-one training? Cheers mc -- Murray Collingwood Focus Computing p +61 415 24 26 24 http://www.focus-computing.com.au
HTML DTD for Tapestry
Hi again I loaded an Eclipse plugin, HTMLEditor from Amateras, and now when I try editing an HTML file it issues warnings about the 'jwcid' parameters. I can try switching the warnings off, although I can't find anywhere I can do this, or I can supply a new DTD that defines Tapestry's HTML syntax correctly. My preference was for help finding errors in my HTML and hence I'm looking for the HTML DTD for Tapestry. I'm assuming there is one, perhaps it should be an extension of the W3C HTML DTD, whatever, if you've got one I think I can load it and it may solve the problem. I checked in http://jakarta.apache.org/tapestry/dtd/ however there were only DTDs for Tapestry and Script. The Tapestry one I have loaded although I think this only reflects the app.application XML file content.

Re: Running the Tapestry Tutorial
Thanks Jesse - I have now been able to load the tutorials. I found the best method was to extract the downloads to some location (not my workspace) and then within Eclipse do the Windows | Preference setting to identify the Tapestry Libraries, followed by File | Import an existing project, browse to the place I extract the downloads and they should all appear in the selection dialog. I'm having one more problem... Syntax error, annotations are only available if source level is 5.0 The line being referenced is in Home.java and reads... @Persist I have loaded J2SE 1.5.0_07 yet still this problem remains. Is there something I've forgotten or missed Cheers mc -- Murray Collingwood Focus Computing p +61 415 24 26 24 http://www.focus-computing.com.au
Re: Running the Tapestry Tutorial
Hi, managed to fix this on my own. In Eclipse there is a setting in Windows | Preferences... under Java | Compiler indicating the compiler compliance level, mine was set to 1.4 and is now changed to 5.0 - this seems to have resolved the problem with the @Persist. I then right mouse on the project's build.xml and run this. The output from my build creates further errors: Buildfile: *C:\TapestryTutorial\directlink\build.xml compile*: [*mkdir*] Created dir: C:\TapestryTutorial\directlink\target\classes [*javac*] Compiling 1 source file to C:\TapestryTutorial\directlink\target\classes [*javac*] * C:\TapestryTutorial\directlink\src\java\tutorials\directlink\pages\Home.java *:8: illegal character: \64 [*javac*] @Persist [*javac*] ^ [*javac*] * C:\TapestryTutorial\directlink\src\java\tutorials\directlink\pages\Home.java *:9: identifier expected [*javac*] public abstract int getCounter(); [*javac*] ^ [*javac*] 2 errors BUILD FAILED It looks as though my ant build isn't picking up the annotations. (I haven't used annotations before so I'm not sure what to do apart from check the compiler compliance for the buildhow do I do that?) Anybodyhhhllp...

Re: Running the Tapestry Tutorial
Brilliant! I looked through the 'Ant Build...' dialog and found there was a 'tools.jar' file being referenced from a v1.4 installation on my computer. There was no 'tools.jar' in my 5.0 library...hmmm? I went hunting on my machine (good on Google Desktop) and found a tools.jar v5.0 in my Program Files directory, copied all of the libs from this area into my v5.0 j2se library and it now compiles perfectly. Now I can start the tutorial properly... Cheers mc -- Murray Collingwood Focus Computing p +61 415 24 26 24 http://www.focus-computing.com.au
Running the Tapestry Tutorial
Hi folks Sorry, this is a real newby question - how do you run the Tapestry Tutorial in Eclipse? I have installed Eclipse 3.1 (C:\Eclipse) and downloaded the Tapestry Tutorial zip. I extracted the Tutorial files into a folder - C:\TapestryTutorial I found a file called INFO.txt and tried to follow the instructions here but they didn't help me find anything to work with. The contents of the Tapestry Tutorial zip look nothing like the directory layouts described on the Tapestry Quickstart page. http://jakarta.apache.org/tapestry/QuickStart/index.html#Pre-requisistes I must be missing something basic - somebody please help.
