Exception:Problem building schema

Hi all,
I want to make a web service call to a service deployed in weblogic, I copied the wsdl to a local file and I created a PartnerLink referring to the wsdl in my local file. I put an Invoke action, create an input variable, everything work fine. However when I try to explore the input variable I got exception:Problem building schema.
Is there anything wrong with the WSDL? I've validate it and it was ok.
Thanks in advance,
santoso
Here is the WSDL of the service:

I've solved it just by upgrading to BPEL 10.1.3.1 (was 10.1.2.0)

Posix Exception

I get the following exception running constantly in the background for 6.0 beta 2 running on Solaris. I believe it happens when making a URLConnection. Any ideas?

I think I solved the problem myself. I noticed when it couldn't resolve the name of the host I was attempting to connect to it would give this error. Fixing the name, the error went away.

Invalid Class Exception problem

Hi whenever i try to run this method from a different class to the one it is declared in it throws invalid class exception, (in its error it says the class this method is written in is the problem) yet when i run it from its own class in a temporary main it works fine, perhaps someone can see the problem in the method code. All its doing is reading from a few different txt files, deserializing the objects and putting them into arraylists for future access.
public void readCourseData()
          CourseArrayLengths cal;
          try

(Class cast Exception)Problem while loading data fro database in java class

Dear all,
Please help me...to solve this
I have a database having two columns of String and Date Types.
In my java code i was trying to load the data to a UI.
I am successfull in loading the String type value.
But while loading date field value,is showing Class cast Exception.
What i am doing is Getting the values from database to a String[] array.
So my question is how to
get the Date field as date field itself,Then convert it to a String..Then put it in to String[] array...
Any body please help...If any one want more clarification in question i will give......

Hi,
I am using GWT to display my data in a Grid.
So it will accept a Single two dimensional String array....Here i have one as String and other as Date.
So i was trying to get each row in a sindle dimensional array array[] then store it in a list.
Iteration goes up to 10 rows.After i am setting it in to a list
ie list.add(array);
Now while returning this list i am doing this
"return (String[][])list.toArray(new String[0][]);"
When i tried to get the date element to String array it is showing class cast exception. When i tried with toString() method it is showing the same problem.

Quick question about an exception problem

Hi all,
I'm doing a homework problem with exceptions and there is an outline I have to fill in with some exception handling. There are 2 parts of the problem I'm not sure about that deal with checked and unchecked exceptions and passing exceptions to a calling method.
Here's the problem: in the following method, the call to getStudentNumber( ) may throw a BadNumberException or a FileIOException. Modify the code (aka add try/catch blocks etc.) to do the following.
1. Pass the BadNumberException on to the calling method. It is not a checked exception.
2. Pass FileIOException on to the calling method. It is a checked exception.
Here is the code outline:
public void reportStudents() {
int number;
while(true) {
number = getStudentNumber();
setStudentNumber(number);
} }I know I need to declare the 2nd exception but I'm not sure the syntax of doing so. Any help would be appreciated. Thanks.

JButton and exception problem

Hi all,
I created a JButton, named open _DB, and add an ActionListener to this. I want that when I click the button the methods in the loop executed (see below for code). However, I always get exceptions. How can I catch these exceptions?
If I use a try-catch loop I got the error:

Mapping Exception problem

Hi ,
I have some problem when i was trying to excute my mapping
it throws below exception.
RuntimeException in Message-Mapping transformation: Exception:[com.sap.aii.mappingtool.tf3.IllegalInstanceException: Too many values in first queue in function useOneAsMany.

can anybody please look into this. and suggest me ..
Regards,
Sandeep

Hi,
One as many node function takes 3 inputs, first is the source value second is the Howmany times the source value should repeat and third one is where the context should change, here 2nd and 3rd input count should same, otherwise it shows an exception.
Follow this link
Introduction to Context Handling in Message Mapping
And one more is we should pass some value to the One as many node function, so put map with default.

IPhone OS + POSIX Thread problem!

Hi,
I'm doing major software porting to iPhone and so far things where going quite smoothly. But right now I've a strange problem with PThreads. Function pthreadgetschedparam(pthreadt thread, int *restrict policy, struct sched_param *restrict param) gives odd priority values related to scheduler policy.
With scheduler policies SCHED_RR and SCHED_FIFO the priority should be 1..99 and with SCHED_OTHER policy the priority should be 0. But in my case (in iPhone Simulator) the scheduler policy is SCHED_OTHER and priority value is 31 which is strange since POSIX standard says that with SCHED_OTHER it should be 0.
So any idea why this? Is it because of iPhone Simulator, is it kernel bug or what?
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/pthreadgetschedparam.3.html#//apple_ref/doc/man/3/pthreadgetschedparam

Ok, POSIX Standard has changed a little bit since the code was written So problem solved, priority can be between min and max while scheduler policy is SCHED_OTHER.

Error 500: com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection
in line
conn = (javax.net.ssl.HttpsURLConnection) url.openConnection();
Where is the problem ??

Sorry, should have been:
javax.net.ssl.trustStore=path/to/etc/etc/DummyServerTrustFile.jks
javax.net.ssl.trustStorePassword=WebAS
Didn't get it to actually work like that though. trustStore & trustStorePassword were always null when I ran my program under WAS5.1.
Here is what I did. If running from command line using WAS5.1 as JRE, first setup the environment:
set JAVA_HOME=C:\Program Files\IBM\SDP70\runtimes\base_v51\java\jre
java -Djava.protocol.handler.pkgs=com.ibm.net.ssl.internal.www.protocol myProgramIndependent of whether running from command line or in RAD7, code in program:
System.setProperty("javax.net.ssl.trustStore",
"C:\\Program Files\\IBM\\SDP70\\runtimes\\base_v51\\etc\\DummyServerTrustFile.jks");
System.setProperty("javax.net.ssl.trustStorePassword","WebAS");(would be better to be able to specify trustStorePassword in WAS than in code though,
but works as such)
One can use some other file but I just added the certificate to DummyServerTrustFile.jks.
Then, unlike I said, one CAN use the HttpsURLConnection, like this:
com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection conn = null;
URL urli = new URL("https://some.address.com");
conn = (com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection)urli.openConnection();
Note this uses classes from C:\Program Files\IBM\SDP70\runtimes\base_v51\java\jre\lib\ibmjsseprovider.jar, so it needs to be in classpath when compiling.
Now this way I didn't get a cast exception from using HttpsURLConnection. The point is one can't instantiate javax.net.ssl.HttpsURLConnection, because RAD7's WAS5.1 can't cast it into its own class (wish it could).
Also, I still couldn't use the javax.net.ssl.HttpsURLConnection.setHostnameVerifier method, because com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection doesn't have it... So the result was pretty much the same as using a HttpURLConnection as I previously instructed. Well, I don't really need that method in practice, but I suppose one might need it in some situation. The IBM URL I quoted said WAS5.1 doesn't really compare DNS host name with the certificate host name though, so I suppose one doesn't need to programmatically set a dummy HostnameVerifier in WAS5.1.

POSIX permission problems

I am running an Xserve, OS 104.11. Straight POSIX permissions, nothing fancy, not using ACLS. For some reason clients can't open files from the server or even copy them to their desktop.
I need to keep the files read only, with the exception of the photolab group, and all others have the ability to open and copy the files to their desktops.
Permissions are set to:
drwxrwxr-x 34 admin photolab 8192 Apr 14 10:14 Master Fashion Archive
Any ideas or suggestions??
Thanks

I assume that you are using workgroup manager? And all users are members of the photolab group? "Master Fashion Archive" is the mount point that the users start at?
Are the permissions on the files inside "Master Fashion Archive" different than those on the enclosing folder maybe? That would explain the clients not having read access...
