JDeveloper and CVS

Hi All,
Just for anybody getting started with JDeveloper and CVS. I've been using both during a while and my comments are:
-- If you are thinking to replace your old CVS System, you really must think about it, JDeveloper just incorporates a little subset of features any CVS System actually has (like eclipse).
-- If somebody have been working with the same code your are using, to know if the code have changed isn't as simple like to make a "check for changes or compare with". Because if you use "JDeveloper Compare With option", JDeveloper check correctly for changes, but for changes over your own last revision, so if somebody create a new revision, you will loose your changes.
well I think JDeveloper creators must make a lot of effort to incorporate CVS functionality, if not, better remove this option from it.
anybody has any comments???

I need to try to understand why you would want to erase a version controlled file in your sandbox from disk but not remove it from version control. I guess we do this automatically because it seems like the right thing to do... it should be noted that this is also the default behavior in Eclipse.
If you remove a file from your sandbox but do not schedule it for removal from CVS, you could basically make changes in your sandbox that will cause other developers to run into compilation errors after you commit and they update.
E.g. SomeClass.java depends on a class defined in AnotherClass.java. You remove SomeClass.java from disk but not from the sandbox. You then rename a method in AnotherClass.java that SomeClass.java had been using. You compile your project, it all seems fine. You commit your changes to the cvs repository. Then your collegue updates and the world is broken.
It seems like a bad way to work. I'd be interested to know what the usecase is for doing this and whether there is perhaps a better way of achieving it (e.g. using working sets or the project content filters).
I'm aware of the issues with the files you mention. They're not really issues with the CVS support as such, they're issues with the parts of the product which generate those files. I know that probably doesn't make much difference to you, but it is relevant in terms of how (quickly) things get fixed.
The xml mergeability of several IDE files (in particular projects) improved greatly in JDeveloper 10.1.3 preview. I've tried very hard to raise awareness in the teams that develop those other features (ADF and Struts) about issues they have with version control. It's sometimes hard to convince people that there's really a problem for some reason. I'm hoping things will eventually improve. You can help that a lot by reporting such issues to your Oracle Support representative so that your specific problems are being tracked as TARs.
Thanks,

Jheadstart, JDeveloper and CVS and TeamWork

Hi
We're four-developer team and we've been working with Jheadstart for some months. Now we want to work with team options that provide jdeveloper (CVS or SCM). But, we are a too much suprised with all the problems that other developers had with CVS, we read it in some jdeveloper forums (JDeveloper and CVS and TeamWork and JDeveloper and CVS
I get very worry about the problems that developers had with CVS and that at last they don't find a better solution than migrate to jdeveloper 10.1.3. All the forums recomend migrate to jdeveloper 10.1.3 for better support of team work, but I read (some time ago) that jdeveloper 10.1.3 still doesn't support ADF, then I assume we cannot use it with Jheadstart, Am I right? Is there a way to use Jheadstart with JDeveloper 10.1.3 Preview right now?
What do you recomend for team work with Jheadstart?
Thanks in advance
Liceth

Liceth,
As you problably know, the JHeadstart team consists of consultants and we face the exact same problems and share the exact same frustrations as you do on an every day basis at our customer projects. It is indeed not easy to use JDeveloper in a multi-developer environment. In all fairness much of this is a given when doing file-based development, and I have seen the exact same problems in situations where other IDE's such as Eclipse etc were used. But using advanced frameworks like ADF and BC4J makes matters more complex, because the declarative way of developing these applications using drag&drop and powerful wizards make you as a developer be less 'in touch' with the file or files that are actually created and updated, and also there tend to be more files in such an architecture that are changed simultaneously by many developers at once.
Merging is the only way out of this mess, and merge tools are not perfect, far from it. They get better and better but at some point you'll need to understand the semantics of the files that are to be merged to be able to merge them correctly, and merge tools will in all likelyhood never become that smart.
Until they do, the only thing one can do is to tackle the problem from the other side: if merge tools dont understand the files they merge, we should take into account the weaknesses of these merge tools, and set up our files so that changes CAN be automatically merged, or in most cases at least. Indeed, JDeveloper 10.1.3 is taking good steps in this direction for notoriously tricky files such as JPR files and such. But the problem will never completely go away.
As for using 10.1.3, well, as you said the preview does not contain ADF so JHeadstart will never run on it. We are developing JHeadstart 10.1.3 that will run on the production version of JDeveloper 10.1.3, but it will be a long time before that release will see the light. And although JDeveloper 10.1.3 is a kick-ass IDE (imho), it will not magically solve all multi-user issues. It will just be a bit more bearable.
Is there ever a real solution for it? I don't know. I have worked intensively with the Oracle Designer product before I switched to Java, and that tool, which uses a database rather than files to store its information, was almost perfect when dealing with multi-user development. It could do so because the level at which conflicts occur is VERY finegrained (so not at 'code line' level but sometimes as far as 'individual properties in a property inspector' level), plus the advantages of instantaneous locking in the database when modifying something. And, thinking of it, it could do so because it dealt with 'structured objects' rather than files, thereby having some 'semantic' information about the data. I have this feeling we can only 'get it right' if we will treat, for instance, a Java file not as a collection of lines of code, but of a structured object tree with members, constructors, methods, parameters etc. etc., and store it as such, instead of storing it as a flat OS file.
Just ranting here (this really should be a personal BLOG entry rather than a forum post, but oh well). As you can tell, its a subject that is very close to every developer's heart.
Kind regards,

JDeveloper and CVS and TeamWork

Hi,
we have a small team with 4 members and are developing in JDeveloper 10.1.2 with CVS plug-in (struts, toplink, jsp).
We are beginners and are frustrated now: every commit/update causes problems.
Always are problems with
- project.jpr files (synchronization among developers)
- sessions.xml (we cannot really add this file to cvs)
- state of offline tables (and digrams) are sometimes wrong show: restart of JDeveloper is necessary
- many JDevelopers files are unvisible, but must be added to cvs
- and more and more
Please - are somebody using JDeveloper & CVS in team with satisfaction? Are our problems beginner-problems or is this way wrong?
Thanks for your experience.
Jara

My biggests issues with JDeveloper and CVS are as follows:
1. Oracle puts out an article that talks about Version controllable XML and the biggest culprits of violators of this rule are the Oracle project files: StrutsPAgeFlow.oxd_struts, ViewController.jpr, and Model.jpr. Not nice when you can no longer open your Struts-config.xml file due to all the <==== lines in the file! In almost all instances, since we've built most of the files and aren't adding/removing much from the project as a whole, we can easily correct these problems then commit again, or just issue a clean update on them, and disregard (especially when it appears to be an ordering issue)
2. Also, we've seen model.jpr files switch contents (areas look like they are swapped around) in between versions. Why? The files are identical except the position of the nodes.
3. I really want to know my OUT-OF-SYNC files BEFORE I do an update. Kind of like the Uncommitted files window, I'd like: Hey, how out of sync am I?
4. The COMPARE utility is very nice, however, once CVS takes over and does the automatic MERGE, you're really left with a mess (at times). Any time we get a "failure to update" message, we issue a compare against the current reposistory version verses version on disk and see what the differences are. Then we search for whether our stuff was merged properly.
5. The only docs I've seen on Jdeveloper and CVS are "introductory" type documentation. Don't put out a document that talks about issues that are "out-of-scope" when these are the very issues that people need to deal with every day, and are looking for answers. The "oracle jdeveloper 10g" handbook is no better, offering about 4 pages of an "overview of CVS".
6. People have asked before about CVS, even on Metalink and an answer from Oracle is to look at an OTN post. I'm sorry, but that really doesn't cut it, especially when your support bill is over $500K/year.
enough rambling...
CVS and Jdeveloper 10.1.2 are working at our shop with 3-4 developers on the project, but it can be paintful during the "conflicts during merge" times.

Best practice: team based development with JDeveloper and CVS?

Hi all!
I was wondering of what is the best way to work with Jdev 9i and cvs on a same project with 5 developers whereas
all developers use the same JPRs and JWS?
Which of the files should be checked in to the central CVS repository, which should be remained on the local machine of each developer?
I assume, all java and xml files might be stored in the cvs repository. But how can we make sure that new files written by a member of the team will be added to my project?
If we also check in the JPR and CFG files the merge of concurrent JPRs will fail and our project will be shreddered ;-)
My question: what is your best experience with simultanous development on same projects?
Any idea?
Many thanks,
Stefan

1. Put everything that your project needs under CVS control:
- buildscripts
- BC4J jarfiles
- BC4J generated files (java, xml, xcfg, jpx, cpx)
- .properties, package.html, gif, ...
- docu
- install scripts
- starter batch or exec, ...
2. Each developer should have a own JPR and JWS file. In a seperate location those files could be checked in frequently to easy allow the setup of a new Developer workstation
3. Use a sourcecode formatter (e.g. jalopy) on the BC4J generated java files to reduce merge conflicts because of empty lines generated by JDev dialogs
4. Adding new files is no problem:
- if you add new BC4J objects (AM, VO, ASC, EO, VL) also checkin the bc4j package XML so new files will be added.
- set in project settings common / input paths - "Scan source path ..."
5. Deleting BC4J files is a problem, because JDev does not automatically remove them from the project. So if someone deletes BC4J objects, you should close the project and delete it manually from the jpr file
6. Close the project before making a CVS update wih external tool like Tortoise because of JDev caches

It asks on JDeveloper and CVS

Like forming it so that several developers can work at the same time, in such a way that there are not conflicts in the project that they are developing?

Alberto,
It is often the case that if you check in the entire Jdev project you will create conflicts any time a developer checks in the project. This will happen almost evertime in a pre 10.1.3 release. This occurs less often in 10.1.3 since each file with a project is not mapped in the project file. There are two approaches to take here either lock the project file under CVS and have an admin update the file, or use source control on all files with the exception of your jdev project files.

Jdeveloper and CVS server

I have connected to my CVS server fine. I am having a problem commiting files. Each time I commit the files I have to manuall increase the version number.
Has anyone worked through this problem before.

- Could you tell us which CVS client you are using?
GNU CVSNT 2.0.8 I downloaded it from www.cvsnt.org
- When you say that you have to manually increase the version number, how are you doing this? Are you editing the CVS/Entries file at all?
I right click on the file in my project. I click commit the Commit to CVS dialog box appears and I have to click on the common options tab. I then click on the Use Revision Number or Tag: and manually enter a revision number.
- Am I right in understanding that your CVS client is not assigning the correct incremental version number to committed files (ie. the version number stays the same after a file is committed)?
I can only do this manually so the version number is incremental so to speak.
- Does the CVS output in the log window show that these files were indeed committed?
Yes. I also can check the files on the server and see that they have been committed.
Thanks,
Sam

Jdeveloper vs CVS (Unable to load taghandler class: /WEB-INF/fns.tld)

I am new for Jdeveloper and CVS.
I migrated a project to JDeveloper. After I compile the project, I can run it. Then I imported the project into CVS. The import is successful. Now I can not even compile the project in Jdeveloper any more. I get errors for all the JSP files.
Error(2): Unable to load taghandler class: /WEB-INF/fns.tld (and other tld files). All the tld files do reside under /WEB-INF
I tried to add tld files as library and additional class paths. Nothing works.
Any idea?
Thanks in advance

Is the JAR file for the taglib in the WEB-INF/lib directory?

JDeveloper assumptions and CVS integration

It looks to me when I'm in Jdeveloper using CVS and I say 'Commit Project folders' or 'Update Project Folders' that Jdeveloper is selecting only the folders that are below the folder the .jpr is in not the folders that are actually in the project. Frankly, we do not want to store the .jprs in cvs overtop of the source tree. We have a single source tree and use cvs to split it up for particular projects see certain sections the whole thing is not under JDevelopers .jpr. How can I make JDeveloper CVS integration recognize that there are other folders that are peers to the folder the jpr is in? It looks to me like I have to now select all files in the System Navigator and do the update or commit or do it outside JDev.
ANy ideas?

Wouldn't this be a question to ask on a ADE forum (if there is one)?
Or you give more info about what you are talking about. Google tells me that ADE is 'Amsterdam Dance Event (ADE)' but I guess this is not what you meant.

Struts Diagram and CVS Problems

We're having a difficult time with the StrutsPageFlow.oxd_struts and CVS. Anytime a developer makes a change to the Struts diagram and commits the struts-config.xml file, the StrutsPageFlow.oxd_struts file also gets committed. When a different developer updates the struts-config.xml file the StrutsPageFlow.oxd_struts file has a conflict on just about every item. We're also encountering this on our *.jpr and bc4j.xcfg files.
JDeveloper 10g is stealing a lot of our time as we're having to manually work around a lot of CVS conflicts on files that are not shown in the project but associated with project files like the struts-config.
Anyone else having CVS issues with these "behind-the-scene" files?

Hi Jason,
Unfortunately, this is a known issue. The only workaround we can suggest for struts at the moment is using an exclusive editing mode. Whenever a developer needs to modify the struts diagram, he should issue a cvs edit. Other developers should use the "List Editors" functionality in JDev to check whether someone is currently editing the file.
We're working on resolving these team development issues in the 10.1.3 release.
Thanks,
Brian

Cannot test portlet using JDeveloper and built-in OC4J

Hi everybody,
I'm not trying to sound stupid but my problem seems to be very basic but i cannot solve it. I'm new to Jdeveloper. Here's my problem.
I'm using Jdeveloper 10.1.2.1.0 (build 1913) to develope a portlet. I deployed it to the built-in Standalone OC4J of Jdeveloper and got the following messages:

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>

</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

10g BPEL process upgrade to 11g hangs in Jdeveloper and Ant script

I have successfully upgraded several 10g (10.1.3.4) BPEL processes and ESB services using Jdeveloper 11g (11.1.1.6.0) migration wizard and deployed them to an 11g environment. Both 10g and 11g environments are up and running.
However, my 11g jdeveloper hangs when migrating the next BPEL process. It hangs at the message box with the title: "Migration Status". I tried the Ant script and it hangs too. It hangs after printing out:
"CompositeRefs
[upgrade] WARNING: UPGBPEL-02009: No Binding setup for : "soapCheckPrivileges"
. This will cause compilation of the upgraded project to fail. Check SOA Upgrade
documentation on manual steps necessary to bind this composite reference. If ne
cessary, upgrade and deploy any dependencies. If planning to retain 1013x nodes
in this projects dependency tree, check earlier part of this log for 1013x WSDL
URLs that can be used."
I guess it makes sense since Jdeveloper and Ant script use the same code base for migration.
One other observation is that if I kill the hanging jdeveloper process and reopen it and go through the migration wizard again, it will be successful without hanging. However, when I fix all the wsdl reference and do a build and deploy to sar. The resulting sar is defective and cannot be deployed to Weblogic even if both build and deploy to sar report success. The defective sar contains only scac.log and scac-log.xml, not even composite.xml.
One difference between this BPEL process and others I have successfully upgraded is that it depends on an ESB service (this esb service has been upgraded and deployed to 11g).
Any ideas?
Thanks,

I will answer my question. I killed the migrating Java process and the migrating wizard will report failure of migrating the .jpr file. Actually, the only thing missing in the migrated .jpr file is deployment profile which I can generate from deployment menu. And I can deploy the migrated process. This works as a workaround.

JDeveloper and JSP

I am a new person to JDeveloper technology.
I wanted to know that if I create JSP using JDeveloper 3.0, and then upload the JSP pages on a UNIX server, will I need application server.
What is JServer ?

Anny,
You can developer Java Server Pages using JDeveloper and deploy them to any platform.
If your deployment platform is UNIX, you will need an application server that supports the Servlet API. Apache plus Tomcat is a good option. You can learn more about it at www.apache.org.
JServer is the VM that runs inside the Oracle8i database. You can learn more about it on the Oracle8i page of OTN.

Oracle's XML Publisher in JDeveloper and XSQL Servlet

A While ago, in this thread JDeveloper 10g, XSQL and FOP , was mentioned an ongoing effort for the "integration of Oracle's XML Publisher in JDeveloper and XSQL Servlet", Is this still happening ?, will this be something will be able to use without having to be an Oracle Apps shop? Any additional info would be appreciated.

Hi,
is there any progress about XML publisher integration with JDeveloper. I'm right now examining XML publisher but there is no explicit directions and explanations of using XML publisher with jdeveloper.
any news !?

JDeveloper and ADF 11g Release 2(11.1.2.0.x) compatible WebCenter Version

We are looking to upgrade ADF to 11.1.2.0 and looking for WebCenter compatibility.
Could you please let me know WebCenter compatible version for JDeveloper and ADF 11g Release 2 (11.1.2.0.x) ?
Thanks
JP

Looking at 11.1.2.0.0 note on
http://www.oracle.com/technetwork/developer-tools/jdev/downloads/index.html
and seeing, "This version of JDeveloper doesn't include the SOA and WebCenter pieces - to use these components you'll need to download Oracle JDeveloper 11.1.1.5.0."
Does that mean, 11.1.2.0.0 can't be used with WebCenter?
