JDev 10.1.3 / Ant / element classes not defined in parent war
I tried to build a WAR file with Ant in JDeveloper 10.1.3 (Preview). The source of the build.xml:
<?xml version="1.0" encoding="windows-1252" ?>
<project name="MyApp" default="war" basedir=".">
<target name="init">
<tstamp/>
</target>
<!-- ... -->
<target name="war" depends="init">
<war destfile="../deploy/myApp.war" encoding="Cp1252" webxml="../public_html/WEB-INF/web.xml">
<classes dir="../classes"/>
<lib dir="../public_html/WEB-INF/lib"/>
<webinf dir="../public_html/WEB-INF"/>
<metainf dir="public_html/META-INF"/>
</war>
</target>
</project>
I got 3 error messages, which do not correspond to the Ant documentation:
- element classes not defined in parent war
- element lib not defined in parent war
- element webinf not defined in parent war
That's why I'm not able to build a war file for deployment.
Is there any chance to bypass/correct the errors?
This bug has been fixed for the Production Release. There is no workaround in the Preview Release. However, these errors should only appear while editing the Ant buildfile. They should not prevent you from running the buildfile.

Error message TD427 (A text element is not defined for form J_1IEWT_CERT)
Hello,
Q> I assign the SAP script form J_1IEWT_CERT to 'SPRO=>Withholding Tax Certificates for Vendor and Customers' and was trying to see the print preveiw. But once I press printpreview button error comes "ELEMENT TITLEDET WINDOW TITLEDET IS NOT DEFINED FOR FORM J_1IEWT_CERT" and i can't see the printprview.
Same thing I tried with the copy of J_1IEWT_CERT from 000 client to ZJ_1IEWT_CERT; but same error is coming.
If i try the printpreview through SE71 it shows without error.
Thank You."test printing" via SE71 only prints what exists in the form. Here your form is missing TITLEDET window and element.
The print program tries to print TITLEDET but it does not exist. Could you check SAP notes to get correct versions of print program and sapscript form. -
How to accept xml even when elements are not defined in its schema
Hi,
I got this requirement where i need to accept xmls even though its schema definition is not available note that i am storing the xmls into obejection-relational mode in oracle xmltype column table.
How can i register schamas which has a perticular element defined conditionally to refer to two schemas based on its elementname (pct:CompanyName and CompanyName), please go through the below given scenario for further clarity on the same
Oracle Version
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
*Sample XML
* <CabInfo>

</CabInfo>
Schema Definition
Cab.xsd
<xsd:All minOccur="0">

pct points to a commontype.xsd file

Now when a xml comes with both the tags pct:CabName and pct:CompanyName then its not an issue however i need to accept xmls which can come as pct:CabName and only CompanyName without the pct namespace referrence.
I was considering choice tags a method to acheive this but i read it cannot be used with ALL i cant remove ALL either from my schema.
Please suggest if this can be acheived.Hello,
You can use module pool to design the screen, all the fields will then remain fixed in the position defined.
CALL SCREEN 100. " 3 fields declared P_NAME p_ROL and P_SUBJECT

I have a class called SUS_WindowsComputerMP, that is an extension of the Microsoft class, Microsoft.Windows.Computer
I'm trying to import CSV data into this extended class and to the base class as well.

BadriHi,
I also tried the pcl.jar in the shared lib in server.xml however still it gives Callback class not found.
Also, I am using JDEV - 10.1.3.4.0 to deploy my BPEL process on the SOA - 10.1.3.1.
I get the following exception while deploying the process. Can this be a cause of the issue ?? Any hints ?

Class Not Found instantiating IP
[Portal 4.0 on WLS 6.1 on Win2K... ]
I'm getting 'Class Not Found' when instantiating my IP class. The only way I can
work around it is to put "WEB-INF/classes" in the startup classpath, which makes
it not re-deployable.
I've read newsgroups/docs extensively and believe that:
* IPs (as opposed to PCs) are scoped to the web app, not to the enterprise app
* For web apps, the WEB-INF/classes (for exploded files) and WEB-INF/lib (for
Jar'd files) should be 'auto-included' in the classpath, hence the classloader
that portal is using for IP instantiation should find my class...
But that's not what's happening... so where is my understanding faulty and, more
importantly, how can I make portal find my IP class and still have it be hot redeployable?
Thanks in advance,
MikeHi,
We actually use a third approach, which is: package your pipeline components
with a dummy EJB into a separate JAR (unless you programmed the actual EJBs
which you want to package with your PCs) and deploy as a separate component
to your enterprise app.
We include pipeline.jar and p13n_util.jar into the classpath in the ANT
script only. WLP starts without these jars in the class path with no
problems.
Just for a reference: we use WLS 6.1 sp2, WLP 4.0 sp2.
Best regards,
Michael Goldverg

Mike,
"The set-environment.bat had been modified to include the WEB-INF/classesunder
the 'sandbox dir' in the classpath. I'm confident removing theseclasspath elements
is the right thing to do; I no longer get the 'class ... can not bedeployed'
messages, which was my original problem."
Yes, putting anything in the enterprise application or the web applicationin
the system classpath is not a good idea.
"So, the (very cool & useful) diag tool"
Glad you like it! I wrote that a year ago, and it has helped me onnumerous occasions.
Whenever you have a classloader problem, this thing works magic.
" 'You need to either put your PC in pipeline.jar or reference your ownJAR from
the pipeline.jar's classpath entry in its manifest.' I'm not sure Iunderstand
this. Are we really expected to modify BEA supplied JAR files?"
Regretably, yes. There have been several ideas on a better solution, butit hasn't
found its way into the product yet. Until that happens, the secondapproach (changing
the manifest classpath entry) is the preferred approach.
"Thank you *very* much for your help!"
I'm happy to help!

Ant deploy from Jdev works fine - same ant deploy from command line fails
Hi
I'm using Jdev 10.1.3 and OAS 10.1.3 and created some web services. I can deploy using the Wizard in JDev - works fine, created a build.xml file using the <oracle:deploy> ant task. Also work fine from JDeveloper.

I have studied the web for suggestion also http://download-east.oracle.com/docs/cd/B25221_04/web.1013/b14431/anttasks.htm#sthref164 but nothing seems to work. Tried copying oracle jars to my ant directory (ant version 1.6.5) but still no success (above error message disappered but other came instead).
Why must this process be so complex. Can anyone help?Hi,
You need to have the following jars in your classpath before firing the ant deploy task.
${Oracle_Home}\j2ee\utilities\ant-oracle-classes.jar;
${Oracle_Home}\j2ee\home\lib\adminclient.jar;
${Oracle_Home}\2ee\home\lib\oc4j-internal.jar;
${Oracle_Home}\j2ee\home\lib\javax77.jar;
${Oracle_Home}\j2ee\home\lib\javax88.jar;
${Oracle_Home}\j2ee\home\lib\jmxri.jar;
${Oracle_Home}\OracleAS_1\webservices\lib\wsa.jar;
Please check your classpath and add the above jars, if not present and try ant deploy task now.
I suppose it should work fine.
Hope its helpful.

Class not Found when accessing Proxy class from backing bean in VC.
Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks

Oracle 10g (10.1.3.1.0) ant-oracle-classes.jar
Hi,
I dint find Ant Task for stopping/starting/restarting the Oracle Application Server, but the http://download-uk.oracle.com/docs/cd/B31017_01/web.1013/b28951/anttasks.htm#BEIHFIIC specifies that you can do so with the Ant Tasks. I went through "ant-lib.xml" present in the ant-oracle-classes.jar, even it does not have these tasks.
Is it by any chance that Oracle shipped a wrong library of "ant-oracle-classes.jar" in Oracle 10g (10.1.3.1.0) is with that of Oracle 10g Release 3 (10.1.3), since this Release 3 does not support the stopping and starting of the server with the Ant tasks.
If any one has any idea, please let me know.
Whom should I report/ask?
Can anyone give some pointers for the same. I would be very very thankful.
Rgds,
Prashanth Babu.Thanks a lot Mike.
But then, the problems donot stop there.
I went though the decompiled code of JSR88StartServer.java and JSR88ShutdownServer.java and found that doStartServer() of JSR88StartServer and doShutdownServer() of JSR88ShutdownServer, both call only one method ie deploymentManager.shutdown(), which is present in J2EEDeploymentManager class.
Ideally, JSR88StartServer should start the server by invoking deploymentManager.restart(). But then, looks like there is a problem here too, since both these methods simply call shutdown only.
And also, whenever I tried restarting the App Server from EnterpriseManager Console, it never restarts. It simply stops and does not do anything apart from that.
Iam in a project where our applications have to be up and running on OAS 10g through automation of deployment ie either thru Ant Tasks or the J2EE Deployment API provided by Oracle. But, both the ways, it looks like there are one-too-many hurdles.
Any inputs to the same would be of great help.
I would just like to know, if any one has done the above. Please let me know.
Rgds,

Class Not Found Exception - applet won't run anywhere outside of IDE
I have an applet that runs perfectly in the netbeans IDE, but won't run from command prompt (I'm using windows) or from a browser. I've been banging my head against the wall for a few days on this one. Here's the HTML I'm using:
<applet width="400" height="525" code="musicapplet.class" archive="crypticgraffiti.jar">
<param name="bgcolor" value="ffffff"> <param name="fontcolor" value="000000">
</param> </param> Your browser is not Java enabled. </applet>
Here is the structure of the jar file's contents:
META-INF/
META-INF/MANIFEST.MF
com/
com/crypticgraffiti/
com/crypticgraffiti/music/musicapplet
com/crypticgraffiti/music/GetNotes.class
com/crypticgraffiti/music/InstList.class
com/crypticgraffiti/music/Mode.class
com/crypticgraffiti/music/MusicCreator.class
com/crypticgraffiti/music/OctaveTransformer.class
com/crypticgraffiti/music/Phrase.class
musicapplet/MusicApplet$playerThread.class
musicapplet/MusicApplet.class
(Musicapplet.class is the main class)
When I attempt to run from command prompt, I get:
"Error: Could not find or load main class crypticgraffiti.MusicApplet"
When I attempt to load via html:
"basic: load: class musicapplet.class not found.
load: class musicapplet.class not found.
java.lang.ClassNotFoundException: musicapplet.class
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)

at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: musicapplet.class
security: Accessing keys and certificate in Mozilla user profile: null"
I have tried every possible variation for the 'code' element of the applet tag (package.mainclass.class, mainclass, mainclass.class, etc). I have also tried compiling with JDK 1.6 and this didn't change anything. I've tried clearing out the cache of temporary files using the java control panel settings, and have verified that my browser can run other applets using JRE 6 and 7.
I've tried some different ways of distributing the applet, also: putting all the class files in the folder with the html file, putting the classes in a source folder in the same folder as the html file, and finally putting a jar in the same folder as the html file (which really seems the simplest).
Any help at all would be most appreciated! This applet is a very cool and original music creating app that draws heavily on the JFugue API. It's a shame that I can't get it online for people to play with!Cryptic Graffiti wrote:

Please note that class names are case sensitive so "MusicApplet" is not same as "Musicapplet" or "musicapplet". Your applet tag should have fully qualified class name (without quotes) and should look like this:
<applet width=400 height=525 code=musicapplet.MusicApplet archive="crypticgraffiti.jar">
</applet>
The JAR should be in the same directory as your HTML file. While launching from command line, you can also check if your JAR file is getting included in classpath.

How do I safely and correctly override equals in a generic element class?
(I posted this in the collection forum, but it was suggested I should take it here instead.)
I've written an OrderedPair element class, (OrderedPair<K,V>), so I can have a set of ordered pairs.
To get the container to treat OrderedPairs as values instead of objects, I had to override OrderedPair<K,V>.equals(Object) (as hashCode too).
So I've written the equals(Object) below in the naive way and I'm now getting warnings about an unsafe cast at line (a) and an unsafe assignemtn at line (b).
I do understand why this is a problem, but I'm not sure what the best solution is.
How does one ask about instanceof for the otherObject, and how does one cast an Object to an OrderedPair<K,V> in a safe way?
public boolean equals (Object otherObject) {
if (otherObject == null || ! (otherObject instanceof OrderedPair<K,V>)) { //line (a)
return false;
} else {
OrderedPair<K,V> otherPair = (OrderedPair<K,V>) otherObject; // line (b)
return this.key.equals(otherPair.key) && this.value.equals(otherPair.value);
}or, more to the point, how does one write a version of equals(Object) for a generic class?
It seems that this overriding of equal will have to be done for many generic element types, so there must be some approach that is safe, yes?
It was pointed out to me that AbstractMap does something similar<warning: thread hijack>
public class OrderedPair<A,B> {
final A a;
final B b;
A first() {
return a;
B second() {
return b;
another question about generic code is this:
is it possible that , most of the time, a generic code may looks like this
(please note that this is not a criticism of the above code which is perfectly ok to me):
public class OrderedPair<A,B> {
public final A a;
public final B b; // no accessor such as getA(), getB()
my point : unless you want specific behaviour linked to value consultation
the actual type of members a and b is not hidden: encapsulation seldom makes sense.
it is known to the user of the parametrized type, it is not subject to maintenance change
so it is public ..... (if it is final)
any remark?

Importing multipage PDF into multi artboard AI doc
Hi folks, The only way I've been able to get a multi-page PDF (with editable vector paths) into AI is to place each PDF page into an AI file with multiple artboards, one at a time. Am I missing something? Is there a more efficient workflow for this?
