Compile errors using bpelx:append

I'm getting compile errors from one particular bpelx:append. I have others earlier in the bpel code, and they seem to be passing the check.
<bpelx:append>
<from variable="set-panel-member" query="/client:set-panel-member"/>
<to variable="setPanel_setPanel_InputVariable" part="setPanelRequest" query="/setPanelRequest/panel/panel-member"/>
</bpelx:append>
Produces:
Error(437):

[Potential fix]: Fix the invalid XML.

</bpelx:append>
</assign>

The code is contained within a Switch block:

</copy>
</assign>
</case>
<otherwise>
<empty name="append.the.rest"/>
<assign name="appendTheRest">
<bpelx:append>
<from variable="set-panel-member" query="/client:set-panel-member"/>
<to variable="setPanel_setPanel_InputVariable" part="setPanelRequest" query="/setPanelRequest/panel/panel-member"/>
</bpelx:append>
</assign>
</otherwise>
</switch>
Any ideas?

We are also receiving the same error. Our process was built for a client in 10.1.2.0.2 and the GUI interface never really liked the bpelx:append statement - it always showed up as an alert/error. But it worked on 10.1.2.0.2
Now that the client is upgrading to 10.1.3, it won't actually compile.
Anyone know of a solution?

ClassCastException using bpelx:append

When attempting to model sample 126 Data Aggregator I receive a ClassCastException. The snippet of bpel code I'm using looks like this:
<assign name="Assign_1">
<copy>
          <from expression="string('one')"/>
          <to variable="outputVariable"
          part="payload"
          query="/ns1:users/ns1:user"/>
</copy>
     <bpelx:append>
          <bpelx:from expression="string('two')"/>
          <bpelx:to variable="outputVariable"
          part="payload"
          query="/ns1:users/ns1:user"/>
     </bpelx:append>
I've tried variations of the query to include "/ns1:users" and also one with no query element. They all result in the exception.
element user is unbounded within users. It's definition looks like:
<xsd:element name="users"
     type="iC.MMIS.WS.tst:usersType"/>
<xsd:complexType name="usersType">
     <xsd:sequence>
     <xsd:element name="user"
          type="iC.MMIS.WS.tst:userCnType"
          minOccurs="0"
          maxOccurs="unbounded"/>
     </xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="userCnType">
     <xsd:restriction base="xsd:string">

<2005-08-14 21:36:53,575> <ERROR> <default.collaxa.cube.xml> java.lang.ClassCastException

That is a corner case that we did not handle properly.
We did not automatically convert a String object into XML text node for users. That triggers that ClassCastException. We shall add that automatic conversion logic into our code. (We have opened a bug - bug # 4554032 - to track this problem down.)
On the other hand, based on the supplied schema, your sample code may not perform your desired logic, if my guess is correct.
Instead of:
<assign name="Assign_1">
<copy>
<from expression="string('one')"/>
<to variable="outputVariable"
part="payload"
query="/ns1:users/ns1:user"/>
</copy>
<bpelx:append>
<bpelx:from expression="string('two')"/>
<bpelx:to variable="outputVariable"
part="payload"
query="/ns1:users/ns1:user"/>
</bpelx:append>
Try:
<assign>
<bpelx:append>
<bpelx:from expression
= "ora:genEmptyElem('ns1:user',2)" />
<bpelx:to variable="outputVariable" part="payload" query="/ns1:users" />
</bpelx:append>
<copy>
<from expression=" 'one' " />
<to variable="outputVariable" part="payload"
query="/tns:users/tns:user[1]" />
</copy>
<copy>
<from expression=" 'two' " />
<to variable="outputVariable" part="payload"
query="/tns:users/tns:user[2]" />
</copy>
</assign>

Compiler error using compareTo

I get a compiler error when I use compareTo with the Character class. I confirmed the error with following code from The Java Tutorial:
public class CharacterDemo {
public static void main(String args[]) {
Character a = new Character('a');
Character a2 = new Character('a');
Character b = new Character('b');
// ******* Problem is here ************
int difference = a.compareTo(b);
if (difference == 0) {
System.out.println("a is equal to b.");
} else if (difference < 0) {
System.out.println("a is less than b.");
} else if (difference > 0) {
System.out.println("a is greater than b.");
System.out.println("a is "
+ ((a.equals(a2)) ? "equal" : "not equal")
+ " to a2.");
System.out.println("The character " + a.toString() + " is "
+ (Character.isUpperCase(a.charValue()) ? "upper" : "lower")
+ "case.");
The compilier is complaining that compareTo is not part of the Character class. I am compiling with whatever compilier was installed with Suse Linux 7.1. The code compiles fine on my university's Unix system that I can dial into.
I figure my Linux version must have some old compiler. But to be honest, I am also new to Linux and am having trouble figuring out what I am compiling with. Can any expert out there give me advice on identifying/updating the Java technology I am using. Thanks in advance.
Jim

Check the jdk version using the java command:
java -versionwhich will output the jdk version you're using.

Urgent: Form Compilation Error using frmcmp.sh on OAS 10.1.2, pls help..

Hi All,
I am upgrading from OAS 9.0.4 to 10.1.2 where Forms 10g application is deployed.
When I try to recompile with frmcmp.sh :
frmcmp.sh userid=system/oracle123@odb module_type=FORM module=menu1.fmb
I get errors :
Compiling Procedure GET_PATH...
Compilation error on procedure GET_PATH:
PL/SQL ERROR 201 at line 4, column 32
Identifier 'APPS_MENU1_DET' must be declared
PL/SQL ERROR 0 at line 4, column 3
SQL Statement ignored
Compilation error have occured.
Form not created
What cause this error ?
FYI, on the above compilation I connect to different database/schema, not the one
which is used by the Form, is this the reason of th error ?
During compilation, Do I have to connect to the database/schema I used when develop the form ?
DO I have to create all tables in the schema first before compilation ?
Tnank you for your hwlp,
xtanto
PS. When I compile the same Form with F90genm.sh on OAS 9.0.4, NO ERROR.

From my experience it's a really bad idea to install OCS into a AS IM. When it comes to upgrades and patches you'll pull your hair out!
Why not install OCS first and then install the BI into the OCS AS server... I have not checked the certification matrix but that might be a better solution to look into.

Compile errors using wsgen (WL 6.1sp2)

I'm trying to create an rpc webservice using the wsgen tool, but I'm
running into compilation errors when the tool tries to compile java files
that it has generated. Attached are the two java files that wsgen generated
for my webservice. The errors are pretty straightforward - there is no
identifier in the package statement. Has anyone come across this problem
before? Here's the relevant console output when running Ant:

Hello,
Could you post your build.xml? Also could you post the log from ant -verbose? Just a shot, but have
you tried building in a directory tree that does not contain spaces in the name?
Thanks,

Odd compile errors using a struct in a vector

I am following Accelerated C++ by Koenig and Moo to learn C++, using Eclipse as my IDE and the MinGW tool chain. Chapter 4 teaches about the struct concept using a pretty simple multi-file example program which emulates reading in a series of student grades and outputs the averages. The struct it defines is called Student_info. Here is Student_info.h:
#ifndef STUDENT_INFO_H_GUARD
#define STUDENT_INFO_H_GUARD
#include <iostream>
#include <string>
#include <vector>
struct Student_info {
std::string name;
double midterm, final;
std::vector<double> homework;
bool compare(const Student_info&, const Student_info&);
std::istream& read(std::istream&, Student_info);
std::istream& read_hw(std::istream&, std::vector<double>&);
#endif /* STUDENT_INFO_H_GUARD */
There are no errors associated with compare, read or read_hw.
The problem I am having is that even though the simple variable declaration below seems to work,
#include "Student_info.h"
int main() {
vector<Student_info> students;
Student_info record;
string::size_type maxlen = 0;
in the sense that the Eclipse code editor signals via i) its color coding that it has found the data type; ii) when I mouseover, it shows me the underlying Student_info definition in the hover box; and iii) the code associated with the variable "record" doesn't generate errors.
However, when I try to use the students vector within main(), I get 'could not be resolved' errors on the property names or 'invalid arguments' for functions which try to pass the variables. For example,
for(vector<Student_info>::size_type i=0; i!=students.size(); ++i) {
cout << students[i].name
<< string(maxlen+1 - students[i].name.size(), ' ');
produces a "Method 'size' could not be resolved" error and a "Field 'name' could be resolved" error.
It's very odd to me, as I said, because mouseover of the vector students declaration at the beginning of main() produces a hover box with the correct struct definition, indicating the include file is being found and contains the intended definition with the 'name' property defined as a string.
I've been trying to solve this for a couple of days and have searched the web and this site, as well as going over all the code many times. The code seems to be exactly what is in the book and it's not too difficult to figure out what it is supposed to be doing. I haven't been able to find a similar error description here or elsewhere by Googling. These errors prevent the project from compiling and so I can't precede. I'm hoping someone can describe what might possibly cause such a thing.
Here's a shortened version of the file with main in it:
#include <algorithm>
#include <iomanip>
#include <ios>
#include <iostream>
#include <string>
#include <vector>
#include <stdexcept>
#include "Student_info.h"
//say what standard library names we use
using std::cin; using std::setprecision;
using std::cout; using std::sort;
using std::domain_error; using std::streamsize;
using std::endl; using std::string;
using std::max; using std::vector;
int main() { // begin main
vector<Student_info> students;
Student_info record;
string::size_type maxlen = 0;
//read and store all the records, and find the length
// of the longest name
while(read(cin, record)) {
maxlen = max(maxlen, record.name.size());
students.push_back(record);
//alphabetize the records
sort(students.begin(), students.end(), compare);
for(vector<Student_info>::size_type i=0; i!=students.size(); ++i) {
// write the name, padded on the right to maxlen+1 chars
cout << students[i].name
<< string(maxlen+1 - students[i].name.size(), ' ');
//compute and write the grade
cout << endl;
return 0;
} // end main
Here are the 'read' functions, which are in a separate file from main and don't seem to be producing any errors:
#include "Student_info.h"
using std::istream; using std::vector;
istream& read_hw(istream& in, vector<double>& hw) {
if (in) {
// get rid of previous contents
hw.clear();
// read homework grades
double x;
while (in >> x)
hw.push_back(x);
// clear the stream so that input will work for the
// next student
in.clear();
return in;
istream& read(istream& is, Student_info s) {
// read and store the student's name and midterm and final exam
is >> s.name >> s.midterm >> s.final;
read_hw(is, s.homework);
return is;
bool compare(const Student_info& x, const Student_info& y) {
return x.name < y.name;
}

Do you mind to try:
for(unsigned i=0; i < students.size(); ++i)
instead of :
for(vector<Student_info>::size_type i=0; i!=students.size(); ++i)

Compiler error using T extends S

The following produces an error on the last call to getWrap.
incompatible types found: A.Wrap<java.util.HashMap> required: A.Wrap<java.util.Map>
Is there anything in the declaration of getWrap to signify that S can be a super class of T?
public class A {
    public static <S, T extends S> Wrap<S> getWrap(T t) {
        return new Wrap<S>(t);
    public static void main(String[] args) {
        Wrap<HashMap> map1 = getWrap(new HashMap()); // compiles
        Wrap<Map> map2 = getWrap((Map) new HashMap()); // compiles
        Wrap<Map> map3 = getWrap(new HashMap()); // incompatible types
    public static class Wrap<E> {
        private final E e;
        public Wrap(E e) {
            this.e = e;
}

From what you are saying, in this case, it appears the T extends S adds no value.
Using explicit paratised types is a bit like casting, in this case casting to a super class.
My preference would be for
Wrap<Map> map3 = getWrap((Map) new HashMap());I have noted before that Java does not consider a desired return type. Some languages do, but imagine this is hard to get right. What I imagined was a return type of getWrap(new HashMap()) of something like Wrap<? super HashMap>.
I have seen generic work very well for return types in other places, however the return type was determined by the IDE rather then the compiler.
e.g.
public interface Visitor<V,T> {
    public T visit(V visited) throws RuntimeException;
// visits an object of type V and triggers optional events of type E
public interface VisitProxy <V, E> {
    public <T> T visit(Visitor<V, T> visitor, Notifier<E> notifier) throws RuntimeException;
public class CollectionProxy<E> implements Collection<E>, VisitProxy<Collection<E>, Event<Integer, E>> {
    private final VisitProxy<Collection<E>> proxy;
    public boolean add(E e) {
         return proxy.visit(new <Ctrl-Space>
// The IDE fills in the following.
        return proxy.visit(new Visitor<Collection<E>, Event<Integer, E>, Boolean>() {
            public Boolean visit(Collection<E> es, Notifier<Event<Integer, E>> notifier) throws RuntimeException {
                return null;
        });Another key turns the anonymous class into a method so I can make it static.
Here the IDE is determining the approriate return type. In this case Boolean which can be unboxed into boolean.
Thank you to everyone who replied.
BTW: This is a simplified example based on a real program.

Help.
(sorry, not sure why this message is ignoring my formatting - makes it a bit hard to read)

Sean,
I just found out the same difference! Something must have gone wrong during the final production build. We have created a new build 10.1.3.1.26 with the correct jar file name, which can now be downloaded from cso.oracle.com.
I apologize for the inconvenience. Anybody that already downloaded 10.1.3.1 build 25, please download build 26, which is the new "official" 10.1.3.1 build number.
Steven Davelaar,

An XJC compilation error - Could not load class (..) for type cvsversion

I've got a strange compilation error using NetBeans 4.0 (I'd guess the version does not matter here) and Ant 1.6.2. When the following task is executed,
<target name="compile_ofx_schema">

<arg value="-nv" />
<arg value="-extension" />
</xjc>
</target>
I get the error from NetBeans console,

That was a great finding from you. Thank you.
I followed your alternative approach and updated the ant.jar file. The "Could not load class..." error went away but the stack trace still remains. Now I am clueless again since I have ant on the debug mode and can't find any more useful info.

Errors using aCC 3.31--- Unexpected 'std'

[Compilation Errors using aCC 3.31/HP-UX 11.0 --

Hi,
I get the following errors when I try to include 'occi.h' in my programs while working with the OCCI classes for Oracle9i database connectivity. Please let me know if I'm missing anything or perhaps do anything different to get rid of this problem.
Thanks for your time.

Yeah, I did use that but it did give me problems when using aCC 3.31. But later on when I used aCC 3.34, it barely compiled with a bunch of Future errors and Warnings. BTW. do you have any specific version of aCC that has to be used with occi.h. Please let me know.
And specifically, when I had to use Rogue Wave Libraries in the program code.
Thanks a lot

Bpelx:append or ora:addChildNode?

Can anybody provide any suggestion on wether to use bpelx:append or ora:addChildNode?
The function ora:addChildNode is documented as being deprecated, and replaced with bpelx:append. But the graphic designer (JDeveloper tooling for BPEL 10.1.2) does not seem to directly support this, and in fact does not even display the code. Since it seems to me having 'invisible' code in a BPEL process might not be such a good thing, I am leaning toward using ora:addChildNode.

I agree, nevertheless the xpath spec clearly states that an xpath expression should not have any side effects - which this one obviously does ..
We have fixed this blind (aka invisible) code in the next version (10.1.3.1).. So from upgrade perspective I would strongly recommend using bpelx:append

Compiler error when useing switch statements in an inner class

I have defined several constants in a class and want to use this constans also in an inner class.
All the constants are defined as private static final int.
All works fine except when useing the switch statement in the inner class. I get the compiler error ""constant expression required". If I change the definition from private static final to protected static final it works, but why?
What's the difference?
Look at an example:
public class Switchtest
   private static final int AA = 0;
   protected static final int BB = 1;
   private static int i = 0;
   public Switchtest()
      i = 0; // <- OK
      switch(i)
         case AA: break; //<- OK, funny no problem
         case BB: break; //<- OK
         default: break;
private class InnerClass
      public InnerClass()
         i = 0; // <- OK: is accessible
         if (AA == i) // <- OK: AA is seen by the inner class; i is also accessible
            i = AA + 1;
         switch(i)
            case AA: break; // <- STRANGE?! Fail: Constant expression required
            case BB: break; // <- OK
            default: break;
}Thank's a lot for an explanation.

Just a though:
Maybe some subclass of Switchtest could decalare its own variable AA that is not final, but it can not declare its own BB because it is visible from the superclass. Therefore the compiler can not know for sure that AA is final.

Weblogic.jspc outofmemory error while compiling jsps using ant in eclipse

--> some error on posting please refer to the next post...
From the error logs we can trace it out to the web project's Build.xml file ....I was getting a similar error and by commenting out the following lines in the web project's Build.xml I am able to run the build script correctly and get a EAR file. The lines are

Please check it now, also if any one can let us know the function or role played by the above lines it would be great. Also if there would be any future or unseen problems by commenting out these lines please do let us know...
Thanks
