Jakarta Poi and Adf

Hi All
I have a requirement to create a web application that interfaces with microsoft com.
I have searched through the forum and the Jakarta poi looks like a good option.
My question is, has anyone integrated jakarta poi with adf and deployed the app to the web application server.
I am using Jdeveloper 10.1.2.
Has anyone done a mail merge ?
Thank you

Jakarta poi and Jexcel

Hello techies,
I want read an Excel sheet using Java. I had gone through net and found two Api's.
One is Jakarta's POI and another one is JExcel.
Iam totally confused, which one i need to implement and is there any performance difference b/w these two api's.
Also can any body tell me from which url i have to download these two s/w and how to install them.

Jakarta POI and Java Excel API

I recently downloaded both these as I'm trying to create an application that reads information from an excel file. However, the problem I am having is that I just don't know where to start. When I download the files and unzip them, I haven't a clue where to put the files or how to call them from my java files. I've read the help files on both the websites but am no clearer on what to do. Any help would be much appreciated.

Download an IDE like Eclipse or JBuilder. Set-up the POI or JExcel JAR files on your new project's class path. Import the relevant packages into the class that will use them. Start typing, autocomplete will help give you a list of classes and methods that are available.
If the above is confusing, start over. Go back and re-read how to import external JAR's onto a classpath. Try to use another third-party API to get the hang of it. Then, do it with POI. Follow the examples, even copy-paste a class into your own source tree and try to compile. Gradually, build up your expertise. Now, go to the Javadocs. You should have the ability to use any class or method published in the API.

Jakarta POI Excel97-2000 (Excel 2003?)

Hi All
I need to read data from Excel 2003 spreadsheet using my java program.
I looked at Jakarta POI, and JDBC-ODBC bridge options.
POI says Excel97-2000
Creating system DSN does not show Excel 2003 options. It shows Excel97-2000, Excel 3.0 etc
My environment is Windows XP 2002.
Can I read Excel 2003 documents using POI?
If I deploy this program on a machine which has earlier versions of excel on it will it be able to read.
I just have plain text in excel spreadsheet.
Please let me know.
Thanks
bib

Hard to answer this question definitively because it very much depends upon exactly what is in the file. If you have saved a complex, formatted document that makes extensive use of features that were introduced into Excel for version 2003 then you will face problems. If the file contains simply plain text, then you should be fine. Most of the API authors base their product on an earlier version of the BIFF8 format to ensure compatibility with as wide a range of Excel versions as possible. That is why they all mention that the API will handle files that are based upon a specific version of Excel. Hopefully, you will be fine distributing the application onto machines that run earlier versions of Excel.
By the way, have you also considered JExcel? It handles a few things differently to HSSF (POI) and you may prefer the way it approaches parsing an Excel spreadsheet file and exposing it's contents.

How to read .doc files using jakarta POI api......

Hi all,
I've googled a lot on reading the file contents of an MS word file. I couldn't get a solution yet. Can you please give some sample codes for using the POI api for extracting only the text contents from an MS word file.
Thanks and Regards,

whenever i click the folders, it's taking
to the internal folders. but there's no
option to download the whole package.Thats because you're looking at a tool which displays the contents of an svn repository through a web site.
What you need is a subversion client (the repository is a subversion repository).
There are several easy to use clients available:
Here's two:
1) subclipse: If you use eclipse. Dammed great tool IMHO. http://subclipse.tigris.org/
2) tortoise svn http://tortoisesvn.tigris.org/
When you've got a client, you'll need to give it a repository URL from which to check out.
For the POI project, that URL is http://svn.apache.org/repos/asf/jakarta/poi/trunk/

Struts and ADF in Portal

Hello. We have had a TAR going for some time regarding an issue with Struts and ADF in Portal. This is the summary of the TAR:
Customer followed the following document to create his Struts ADF application:
Developing an End-to-End Web Application Using the Default Technology Scope
at
http://www.oracle.com/technology/obe/obe9051jdev/ADFtoJSP/defaultendtoend.htm
After following the steps in the documentation, his application worked just fine.
- After this he decided to portletize his application using the following document:
OracleAS Portal Developer Kit (PDK)
How to create a Struts Portlet ?
at
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/pdkstruts/portletize-your-app.html
When adding his portlet to a page, he basically received a portlet without any data, while the same worked fine outsi
de of Portal.
These are examples from the JSP file that do not show up in the portlet:
<c:out value="${bindings.DepartmentsView1.labels['DepartmentId']}">
<c:out value="${bindings.DepartmentId.label}"/>
</c:out>
We figured out that if we add the following filter mapping then it works fine:
<filter-mapping>
<filter-name>ADFBindingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This filter mapping would mean that it maps all URLs to the ADFBindingFilter. I suppose this would not be necessary and we're concerned about the implications this might cause and we believe that there should be a better solution for this.
The final reply from support was that Portal is not yet supported with ADF technology. Does anyone have any comment on the above filter issue and other thoughts on using Struts and ADF in Portal? Another issue we found was that the PDK Struts tags do not support EL expressions. Have a look at this forum post:
Re: Struts and nested tags in parameters. Possible?

Very beginner POI and import question

I am reasearching/playing around with the Jakarta POI. My boss would like to load word docs/xls into the database in binary form - he then wants to display them Read Only to the end users. He suggested that I look into using the POI.
I've been reasearching the forums here and google but I havent found a great example implementing this. Everything I have found is way way over my head. Could someone point me to a very simple example of doing this? Or give me a very basic skeleton of what I would need to do to just open a word doc - I am trying to use this time to teach myself how to use/read the API(poi) - if that makes any sense...
Secondly - while I was reading on POI I ran across this: import java.io.*; // don't ever do this...done to save space I know it says it is to save space but is that because it imports all the classes under IO? I know its a stupid question but I have seen it in other examples and use it in other jsp's... I just copied and pasted so I didnt really know why or what I was doing...
Source of comment: http://www.onjava.com/pub/a/onjava/2003/01/22/poi.html - Appendix 1/ Example 1

Also wanted to add that my boss would like to store
the file as binary into database, extract the file
from database, change it back to native format in a
temporary directory and then use the POI to present it
as read only??
Is there any easier way? This still just seems like a
straight forward process being made harder then it
is...I thought i just told you how to do all of that?! You can only really store documents and files etc. as binary in a database column, unless the file is plain text (which these are not) and even then you would lose all of the formatting. So, don't worry about the binary aspect of it, as you will prob be storing the file as a BLOB anyway. You don't have to change the file back to its native format either, as if you have stored a file as binary, and you know the name (most importantly the extension), then when you write the binary to a file of that name, it IS in the original format. You can write a java webDAV client easily with the tools and libraries available in such packages as Jakarta Slide. In the past this API has been... lets just say, hard to grasp... due to documentation problems, delayed features etc. However, the traffic around the project seems to have increased dramatically since I last used it properly. Plus, you can extend this store to manage any kind of document or file.
Oh and by the way, I would suggest you try to do this on the web... basically because IE (as prob with other browsers) can view MS office docs in the browser window itself. Very helpful thing that!
Is this helping you or not?

Apache Jakarta POI in PL/SQL

Jakarta-poi-1.5.0-FINAL-20020506.jar

Where do I download jakarta-poi-1.5.0-FINAL-20020506.jar from ???
Can anybody help me ???

Hi Friends,
I'm also on the same track. I download the jw-0332-poi from Resources of http://www.javaworld.com/javaworld/jw-03-2004/jw-0322-poi.html
I compile CreateXL.java & ReadXL.java files & got compilation errors like:
"cannot resoleve symbol class HSSFWorkbook
"Cannot reslove symbol class HSSFSheet"
and more error for HSSF package from org.apache.poi
To solve this I download "poi-bin-3.0-Final-20070503.zip" from http://www.apache.org/dist/jakarta/poi/release/bin/
and poi-src-3.0.1-FINAL-20070705.zip files fromApache download mirrors. i put it in classpath & then compile but still I got the same error.
I didn't find jakarta-poi-1.5.0-FINAL-20020506.jar on http://www.apache.org/dist/jakarta/poi/release/bin/
From where should I get the jakarta-poi-1.5.0-FINAL-20020506.jar ?
I would appreciate your help for this topic.

Jakarta taglibs and iWS4.1

Is it possible to use the Jakarta custom tag libraries with iWS4.1 SP11?
I am able to make the custom tag samples work (http://docs.sun.com/source/816-5680-10/2-examp.htm#21044). But I can't figure out how to plug in the pre-built custom tag libraries from Jakarta.
My goal is to use XSLT to dynamically display XML documents. It runs on Tomcat, but it needs to run on iWS4.1
Any input is greatly appreciated.
Thanks

This is not an Apache site. It is not even the Oracle JSP forum.
I suggest you try the JDeveloper site, which you will find JDeveloper and ADF, where at least they all speak Java. There is also the J2EE forum, although that seems somewhat less OC4J. And of course there is a designated Java Server Pages (JSP).
Cheers, APC

ADF table and ADF form on the same view object

Hi,
As per the ADF demos available on ADF site, I created a jsf page with 2 panels. One panel is an ADF table based on a view object. And the other panel is and ADF form based on the same view object. My requirement is that as I scroll through the records in the ADF table, the ADF Form should dynamically display the details of the record in the ADF table. My understanding is that this should be automatic. However, its not working as expected. What have I missed?

Hi,
Apply PPR for form that displays details.
Like :
<af:table id="t3">
</af:table>
<af:panelFormLayout id="pfl2" partialTriggers="t3">
</af:panelFormLayout >

JDev and ADF is difficult

As a new user to ADF I am finding ADF and JDev a little discouraging and hard to use. I did a search on how to improve jdev's performance and found a lot of useful tips and tricks to use, but I pose the question. Shouldn't it just work out of the box? Coming from a web 2.0 background developing EE applications using Spring, JPA/Hibernate, Extjs, and netbeans I keep thinking to myself wow how in the world should I have known that changing this or that table attribute causes this or that to behave differently. For example I read a thread on multi-selecting table rows and in this article multiselect selectedRowKeys must be removed for multi select to perform correctly. Now I realize this is a simple example, but I find myself asking the same types of questions about dragging and dropping views into jdev or mapping bindings to pages so that I can gain access to data. I can relate to some angry posts by some about how difficult it is to develop anything useful in JDev and ADF because of a series of random problems (things like running OOM, or mapping bindings to a page which then for some reason map incorrectly or they think they are mapped to another page, etc...) Now I can already hear the first response... you are new to this world (yes) and you just need time. What if I told you I've been reading so much documentation over the past month that my eyes are bleeding. I've been through countless tutorials on how to use JDev and ADF. I've successfully created "Sample applications" generating useless tables of data. I've read several books on ADF and how to button click my way to creating EE applications, but I find the memorization of button clicking to be exhausting. I keep telling my boss I want to go back to writing code not dragging and dropping items on a page so that JDev can generate/modify .xml files for me.
Now that said I know I am new to this world and I'm trying to find some common ground as my job requires me to develop EE applications in ADF, and I must learn this technology. So I ask all of you ADF and JDev advocates prove me wrong here and point me to the documentation that all of you use to navigate this world of yours.
Thanks for your understand,

First off thank you for the response Shay!
>
Getting used to the way you build applications with JDev and ADF takes time, but think how much time did it took you to learn Spring, JPA, ExtJS etc to a level where you knew every little setting you needed to manually code in a spring XML file, or JPQL query syntax in your JPA or a javascript in ExtJS - My guess was that getting to a situation where you know everything in those technology wasn't exactly a problem less experience.
>
It is true it took some time to learn the technologies listed above. I guess If I were arguing for them I would say they were easier to use and learn due to most of them being open source and very popular because of this (i.e tons of examples, books, and documentation). Not sure if ADF is there yet?
>
I do like the fact that I can get from 0 to a fully functional page with a few clicks here and there, and then fine tune the results with some property settings in various places.
And then if I need even further customization I can go to the code level when needed.
>
I agree it takes very little time to create something that is at least visually usable. I'm not familiar enough ADF yet to determine now hard it is to actually create a fully functioning application that does more than display data. For example, how would I create a visualization that updates every 10 seconds and allows users to post feedback in a similar manner to this forum?
>
The question of whether the declarative and visual development experience is a good thing or not is to some degree a matter of personal preferences.
I wonder how long would it have taken someone to build something like this: http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/ADF112/ADF112.html
with the stack you mentioned above. How many lines of code would they have needed to write, how many syntax errors while coding, and would the result be as functional so fast.

Agree I'm not hear to argue which type of development experience is better or worse. I would point out however that as a JDev/ADF developer in order to develop in the technology it seems you must do most of your development within the JDev environment or have extensive experience in JSF (i.e know which xml files to edit and why I believe there is a reason JSF and JSP are seldom used IMHO because they are difficult. I understand JDev/ADF try to solve this problem) were as in other technologies you as the developer can choose the IDE etc. Another thing I noticed while watching the link you listed was the developer went from place to place to place within jdev making changes. As a newbie it seems that in order to develop ADF in JDev you must just "know things" (ie. for example he pulled in a method in to the task flow so he could invoke some validation or prereq check. As a developer how am I to know how and where and why I can/must do these things? ADF seems to be process based in order to achieve some goal, but the JDev framework gives no clues as to what you should/need to do next. As well as that I needed to create that method within my Application Module in order to do this, which by the way was not mentioned within this video.).

We often see the reaction of "I don't get what all those XML files that JDev generate are doing" reaction from people who just start up with JDev and ADF.
But we do try and explain how everything is working in places like the ADF Insider Advanced seminars:
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfinsider-093342.html
I think the fact that there is a lot of documentation for ADF, and a lot of blog entries, how-to's etc on the web is actually a good thing.
I often find that if I run into an issue with ADF - a simple google search will show me how someone else solved that issue - and I like this too.

I guess my biggest gripe here would be yes there is tons of JDev/ADF documentation on OTN and other places, but none of it is complete, and I would also argue that the organization on OTN is half hazard, and makes learning ADF difficult as well. I find myself drilling down through layers and layers of links only to not be able to get back to were I came from to look at another topic/tutorial I was interested in(maybe we need a ADF train to be added to the documentation wikis).
I would also argue when developing in other frameworks writing the xml is a big part to understanding how your application is tied together. For example, Spring servlet mapping or Spring injection mapping. When JDev does the mapping for me I feel that I know less and less about how my application works and I bet all the advanced ADF developers out there know quite a bit about how ADF xml mapping occurs and why, and I bet they make changes to these xml files manually quite often to get things to work as they desire?
I want to be clear here I am not trying to flaming here, just trying to make a difference for other developers like myself who come along and need to learn ADF to complete some task. Looking at the OTN site I believe creating documentation for ADF development appears to be a top priority, but due to the complexity of the framework there is just so much and it seems to be everywhere. My suggestion would be to include why we are doing such and such with in jdev approach instead of a drag this here to do this approach. For example, I'd like to see a tutorial where it explains when you drag this item in to the content window it creates this xml bind which is the same as what you would normally do in JSF like this (if anyone knows of such a tutorial plz link).
Again thanks for the reply, and I encourage others to give feedback and suggestions on how I too can become a better JDev/ADF developer.

BPM and ADF integration - some questions

Hi,
I have a few questions about comunication between BPM 11.1.1.5 and Human Task based Task Flow:
1) What is the best way to pass data (task id, proces id, proces data) from BPM workspace to Human Task Task Flow (and get them as TF params).
2) Where can I find a description, how ADF app comunicates with BPM process.
3) Where can I find a description of all data controls created by JDeveloper (BPM Suite) when HT Task Flow is created.
3) Where can I find a description (and their functionality) of managed beans created by JDeveloper (BPM Suite) when HT Task Flow is created.

Hi,
Sory, but I'm still not sure, how ADF comunicates with BPM (I know that it uses EJB services and hwtaskflow.xml). But a still don't have an answers for follwowing questions:
1) I know ADF quite good. Having method in data controls (in our case getTaskDetails()) we need to invoke it somehow. I don't see anywher invokation of this method.
2) In generated task flow there is some managed beans and params - what is role of them ? Having over 50 task flows , do I need it in all of them. Where can I find description of those beans and params
3) In our approach we use BPM , ADF RC for UI and Business Components to persist data into database. Only data from payload we need is ID of master-level row. My question is - do I have to generate data controls for all human task ?. In my my opinion it should be only one communication point between BPM and ADF but not the same for all pair human task --> task flow.
All infomation I need from BPM is:
- task ID
- task flow name (to open apriopriate tab in my application)
- available outcomes
- to know is BPM operation is enabled

Trinidad and ADF Rich Faces components::

Hi!
Does someone know about any problem while using Trinidad and ADF Rich Faces, or just the Trinidad components in JDev11g ?
Thanx.
Endy

Endy,
ADF Faces RC isn't supported in IE6, so that certainly wasn't the issue. I have inadvertently mixed Trinidad and ADF Faces RC components on a page and didn't run into issues, but I did correct that issue based upon comments from Frank/Shay on the forum. Bottom line is that while they may work (or appear to work) together, it's not a supported combination.
Best,
John

HELP: include another page in with JDeveloper and ADF

Hi all,
I am trying to make a layout page with JDeveloper and ADF. But I just can't make things work. I have the pre-coded header and footer html pages and want to include them in a jspx somehow. I tried panelPage too, but the rendering style is away from our pre-coded header and footer.
1. Use jsp:include.
header works fine but footer is rendered before the page content, even if the footer is placed after the page content. Is there a way to customize the position?
<f:facet name="footerFacet">
<f:subview id="footerView"
binding="#{backing_welcomePage.footerView}">
<jsp:include page="/footer.jspf"/>
</f:subview>
</f:facet>
2. Use frameBorderLayout.
I followed the doc and use the document tag. But the frame page is rendered but none of included pages are rendered. So I got a blank page.

<f:view>
<afh:html>
<afh:head title="my frame page">
<meta http-equiv="Content-Type"
content="text/html; charset=windows-1252"/>
</afh:head>
<afh:body>
<afh:frameBorderLayout height="100%" width="100%">
<f:facet name="center">
<afh:frame source="topPage.jspx" name="topPage3"/>
</f:facet>
<f:facet name="top">
<afh:frame source="topPage.jspx" height="200" name="topPage2"/>
</f:facet>
<f:facet name="bottom">
<afh:frame source="topPage.jspx" height="200" name="topPage1"/>
</f:facet>
</afh:frameBorderLayout>
</afh:body>
</afh:html>
</f:view>

<f:view>
<af:document title="FrameBorderLayout Demo">
<af:form>
<af:panelGroup layout="vertical">
<f:facet name="separator">
<af:objectSeparator />
</f:facet>
<af:outputFormatted styleUsage="instruction" value="<b>A frameBorderLayout</b>"/>
</af:panelGroup>
</af:form>
</af:document>
</f:view>

for #1 have you tried throwing a verbatim tag around your includes like:
<f:verbatim>
<jsp:directive.include file="/includes/footer.jsp"/>
</f:verbatim>
it's how we got around intermixing html and jsf
