XSL transformation with java binding

Hi everyone!
I am trying to implement na XSL transformation that uses java code binding.
My XSL looks as follows:
<i><xsl:stylesheet xmlns:myobj="java.lang.System" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xf="http://www.sapportals.com/wcm/app/xmlforms">
<xsl:param name="myobj"/>
<xsl:value-of select="string(myobj:currentTimeMillis())"/>
</xsl:stylesheet></i>
Everything works fine - current time is displayed.
But when I try to use my custom java class the compiler returns an exception:
<i>com.sapportals.wcm.WcmException: com.sap.engine.lib.xml.util.NestedException: Could not load class: ep.UmeLookup required for execution of 'UmeLookup.isReady'</i>
My second xsl stytesheet with a reference to custom class looks as follows:
<i><xsl:stylesheet xmlns:ume="ep.UmeLookup" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xf="http://www.sapportals.com/wcm/app/xmlforms">
<xsl:param name="ume"/>
<xsl:value-of select="string(ume:UmeLookup.isReady())"/>
</xsl:stylesheet></i>
I developed java class (ep.UmeLookup), made a .jar from it, included the jar archive in a Library project and deployed the library to the J2EE engine.
It looks like my class is not 'visible' in J2EE engine, while in my opinion it should be. Does anyone know how to change that??

Issue with XSL transformation in Java Stored Procedure

Hi,
Am having issue applying XSL transformation in Java Stored procedure. I have loaded the java class as well as .XSL files through loadjava uility and their status in DB is VALID.
Below is the code in the java stored procedure:
public static String tranform(String strInputXML ){
URL url = ClassLoader.getSystemClassLoader().getResource(first.xsl);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new ByteArrayInputStream (strInputXML.getBytes("UTF-8")));
TransformerFactory tFactory = TransformerFactory.newInstance();
StreamSource stylesource = new StreamSource(url.openStream());
Transformer transformer = tFactory.newTransformer(stylesource);
When I run this procedure, am getting following errors:
{color:#ff0000}*ERROR: 'No such file or directory'*
FATAL ERROR: 'Could not compile stylesheet'{color}
My first.xsl file has reference to other excel file (Ex: <xsl:include href="second.xsl"/>) which seems to be causing this error. When I remove the reference, procedure is working fine.
Pls let me know how to resolve this and read the .XSL file with references.
Thanks,

Hello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks

XSL transformation with xsl:import generates exceptions

I am using the Schematron's basic XSL file basic-schematron.xsl to validate the XML format of one of our data files. The XSL file looks something like this
================
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias">
<xsl:import href="skeleton1-5.xsl"/>
<xsl:template name="process-prolog">
<axsl:output method="text" />
</xsl:template>
==================
But, the validation fails while trying to run the transformation on my Schematron input file using this basic-schematron.xsl with java.lang.NoSuchMethodError:
======= OUTPUT ============

I tried the individual JAXP 1.3 for J2SDK 1.4.2 (Using the -Djava.endorsed.dirs JVM param) and tried the JDK 1.5.0_02 which has JAXP 1.3 inbuilt and they all fail.
I tried the above with separate Xalan/Xerces jar files, and then it works fine.
The problem seems to be somthing specific to the JAXP 1.3 environment. I can provide more details, if required. Any help is highly appreciated.

One morning your code woke up and found it had been transformed into a giant insect.
But seriously, here's the name of the method that doesn't exist:GregorSamsa.process$dash$rootIs GregorSamsa your class? Maybe your server has an old version of it which is missing that method? (Or: those $ signs look strange to me, maybe they are a mistranslation of some other character?)

Oh well, yes it was a typo in address tag...ok agreed that its a bad example, check this out then,

Xsl transformation in java

Hi all,
Firstly let me start by saying sorry if this is the wrong place for this question. And if anyone thinks so and can suggest a better forum for my question, please suggest it!
My question is regarding the xsl tag <xsl:for-each> with the select attribute.
This element in xsl is very useful, and also convenient in the way it works. It iterates over a set, selecting the current position in that set, and making it the current context for your xpath. What I mean can be seen below in my small xsl snippet. I am selecting a position, and after that i can
use the current context to output the value of the child node 'name', the element which xpath would otherwise be
/PatientRecord/History/Episode[@current='true']/Partner/name, but since the for-each makes the current position in the set the current context, I can refer to it just by 'name'.
<xsl:for-each select="/PatientRecord/History/Episode[@current='true']/Partner">
     <xsl:if test="name/@label">
               <tr>
                         <td id="pd_col_left"><xsl:value-of select="name/@label"/></td><td id="pd_col_right"><xsl:value-of select="name"/></td>
               </tr>
     </xsl:if>
</xsl:for-each>
QUESTION
I have wanted to select an XPATH and then use that context to more easily (short form) access all child nodes, EXACTLY AS IN THE SNIPPET ABOVE!
And because I don't know any other way (and haven't found reference to such a method) I have simply been using the <xsl:for-each> tag for this case even though I only want to select one exact position, and do not have or want to iterate over a set+.
I have the feeling I should probably be doing something like an xsl:template match"blah"
But I am just not sure how to ensure the template is called at the correct time in the run of the transformation.
I am not sure, because you are not able to nest these xsl:template tags...... .so....
Just how would it look?
What is the correct way to go about this? ( I am admitedly still getting used to this way of thinking/coding)
Thanks in advance for any help!

No, you don't want <xsl:apply-template>, you want <xsl:apply-templates>. Look for examples which use that element. It will take you a little bit of practice to get yourself free of the procedural programming style (where you control what order things happen in). The natural style in XSLT is to let the processor control the order things happen in, and to set up templates which match on the right XPath expressions.

Xml transformation with java

Hi, I am new to java, and was looking for some java code to accomplish the following:
I have an XML file, and a target XML schema. I also have a mapping schema, that maps the source xml file attributes with the target schema attributes.
I want to read the input xml file, and then reformat it to conform to the output xml schema(validated).
Will appreciate if someone can point me to code for a similar problem .....!

Transform the input xml to an XML document which conforms to the target schema with a XSLT.
http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXPXSLT2.html
Validate the XML document with the target Schema.

Lookups with java:comp/... not working

Hi,
when I bind an object to the jndi tree, e.g. "/mysubcontext/myobject", I
can't perform a lookup on "java:comp/mysubcontext/myobject". If I try to
lookup "/mysubcontext/myobject" it works fine. Isn't the lookup with the
java:comp prefix supposed to do the same?
Thanks,
Daniel

thanx this is the solution. With this construct
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:variable name="temp4" select="$temp3"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>
</xsl:stylesheet>
at least the '3' is added to the vector.

XSLT with java extensions not working with jdk 1.6

Hi,
in as XSL transformation I'm using java functions in some cases. With jdk1.5 this works fine. But when switching to jdk1.6 it seems the java classes are not properly initialized.
See following simple XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>
</xsl:stylesheet>
With jdk 1.5 it creates following output:
3
[1, 2, 3]
With jdk 1.6 I get:
0
So I can access the object in jdk 1.6 but adding doesn't work.
Anybody has an idea what could be wrong or how to fix this?

thanx this is the solution. With this construct
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:variable name="temp4" select="$temp3"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>
</xsl:stylesheet>
at least the '3' is added to the vector.

What am I missing?

Sparks,
Any reason you are not using the VerticalGrid Applet?
Did you specify any of the parameters required by the XSL, such as ColumnID and ValueID?
The XSL appears to only translate a single row node to a column....
Try using this XSL:

XSLT-transformation in Java-Mapping with javax.xml

Hi,
we wanna use javax.xml for transformations in Java-Mapping.
Inside the Java-mapping we read in XSL-files to transform a XML-stream. With XSLT 1.0 everything works fine - but with XSLT 2.0 we are getting runtime errors.
Is it possible that javax.xml only supports XSLT 1.0?
Regards
Wolfgang

Hi ,
Jaxp 1.3 is available in this link -
http://java.sun.com/webservices/jaxp/
Use these jar files to process XSLT 2.0.

Error using custom xpath function with XSL transformations in BPM

Hi,
We have created a custom xpath function for use with SOA Suite and BPM. This has been built as per specified within the http://docs.oracle.com/cd/E29597_01/dev.1111/e10224/bp_appx_functs.htm#SOASE11100. We have also reviewed the Oracle Sample for mapper-107-ExtensionFunctions (sample demonstrates the use of user-defined extension functions). This has been registered with jDeveloper and SOA within the oracle.soa.ext_11.1.1 (run ant to include in oracle.soa.ext.jar)
We ideally want to use this is BPM within an xsl. However when consuming this function is either BPEL or BPM using an xsl, the xsl fails with an error such as:
XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is ora:doXSLTransformForDoc("xsl/Transformation_1.xsl", $inputVariable.payload). The XPath expression failed to execute; the reason was: javax.xml.transform.TransformerException: oramds:/deployed-composites/default/gwCustomXpathUtil_rev1.0/xsl/Transformation_1.xsl<Line 9, Column 113>: XML-22043: (Error) Extension function error: Method not found 'getWeekDayDate'. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
In an Assign it operates fine and returns the expected result. We have included a combination of both of the Config files (ext-mapper-xpath-functions-config.xml and ext-soa-xpath-functions-config.xml) in the META-INF folder, however neither allow the use of this function in the XSL.
I believe there may be an issue getting the custom xpath functions within XSL files. Hence I have also raised an SR. Has anyone experiences of this?
Our SOA / BPM suite environment is using 11.1.1.6.4 and has the following patches applied:
13801175
14406487 (11.1.1.6.4 SOA Bundle)
13896993

Execute PL/SQL block with named binds from within java code?

Hi guys,
Is there any good way to execute my PL/SQL code, for example
BEGIN         :x := :x+1; END;
from my Java code? I need nothing complicated, just static code block with named binds.
I have tried the Oracle exetnded JDBC (setXXXbyName methods):
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password"); String SQL="begin :x:=:x+1; end;"; OracleCallableStatement stmt; stmt=(OracleCallableStatement)conn.prepareCall(SQL); stmt.setIntAtName("x", 5); stmt.registerOutParameter("x", Types.INTEGER); stmt.execute(); System.out.println(stmt.getInt("x"));     } catch (Exception x) { x.printStackTrace();    }   }
And get the java.sql.SQLException: operation not allowed: Ordinal binding and Named binding cannot be combined!
Then i've tried SQLJ appoach:
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password");       Oracle.connect(conn);       System.out.println("Connected!");           int x=3;       #sql { BEGIN         :x := :x+1;       END; };           System.out.println("x=" + x);     } catch (Exception x) { x.printStackTrace();    }   }
And x=3 had retuned... Although 4 expected.
Then, I've set parameter sqlj.bind-by-identifier=true
And result is another exception! java.sql.SQLException: Missing IN or OUT parameter at index:: 2
Can you please mark my mistakes/point to correct solution?
Thanks in advance,
Alexey

Found another solution, this time working at least...
public void testPLSQL() {
       String dynamicSQL=
            "declare\n" +
            " v_CursorID INTEGER;\n" +

            " v_Dummy     INTEGER;\n" +
            " v_x         String(18);\n" +
            "BEGIN\n" +
            " v_CursorID := DBMS_SQL.OPEN_CURSOR;\n" +
            " v_BlockStr :=?;" +
            " DBMS_SQL.PARSE(v_CursorID, v_BlockStr, DBMS_SQL.V7);\n" +
            " v_x:=?;"+
            " DBMS_SQL.BIND_VARIABLE(v_CursorID, ':x', v_x,18);\n" +
            " v_Dummy := DBMS_SQL.EXECUTE(v_CursorID);\n" +
            " DBMS_SQL.VARIABLE_VALUE(v_CursorID, ':x', v_x);\n" +
            " DBMS_SQL.CLOSE_CURSOR(v_CursorID);\n" +
            " ?:=v_x;"+
            " COMMIT;\n" +
            "EXCEPTION\n" +
            " WHEN OTHERS THEN\n" +
            "    DBMS_SQL.CLOSE_CURSOR(v_CursorID);\n" +
            "    RAISE;\n" +
            "END DynamicPLSQL;";
       try {
               Class.forName("oracle.jdbc.driver.OracleConnection");
               Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user", "password");
               System.out.println("Profit");
     String SQL="begin :x:=:x+1; end;";
     OracleCallableStatement stmt;
     stmt=(OracleCallableStatement)conn.prepareCall(dynamicSQL);
     stmt.setString(1, SQL);
     int x=3;
     stmt.setInt(2, x);
     stmt.registerOutParameter(3,     Types.INTEGER);
     stmt.execute();
     x=stmt.getInt(3);
     System.out.println(x);
     assertEquals(4, x);
       } catch (Exception ex) {
            ex.printStackTrace();
            assertTrue(false);
}Now the only thing I need is to code some kind of preprocessor of SQL block, to prepare the dynamicSQL lair for SQL critter...
Please please please show me something less complicated! :8}

Error with XSL Transformation

From my application log I see an exception where it tries to call the oracle.xml.parser.v2.XSLProcessor.
The servlet for the login screen (XSL transformation) takes XML and returns HTML. Actually for the xml parsing
we use xerces I don't understand why we would call the ORACLE parser? Do you have any idea? Is this a CLASSPATH
or configuration problem? Is there a way to use the xml parser xerces instead the oracle one.

11G: Error invoking adf-binding service in composite with JAVA API

Hello,
i'm trying to invoke a asyncrhonous composite via JAVA API. My composite has two services: WS and ADF-BC SERVICE both of two are wired with a MEDIATOR that connects with two BPEL Process depending on two rules.
I need to invoke a process depending of the input: if the input is A i invoke the process 1 and if the input is B I invoke the process 2. I use the Mediator instead of switch because it's an example in order to build a complex decission system then.
R1 and R2 are two static rules in the Mediator.
R1 = $in.payload/client:process/client:tiposiniestro = 'A'
R2 = $in.payload/client:process/client:tiposiniestro = 'B'
And my XSD is:
<schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/POC_jws/ProcesoApertura/ProcesoApertura"
     xmlns="http://www.w3.org/2001/XMLSchema">
<element name="process">
          <complexType>
               <sequence>
                    <element name="tiposiniestro" type="string"/>
               </sequence>
          </complexType>
     </element>
     <element name="processResponse">
          <complexType>
               <sequence>
                    <element name="result" type="string"/>
               </sequence>
          </complexType>
     </element>
</schema>
If i invoke with SOAP, sending the message:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Body xmlns:ns1="http://xmlns.oracle.com/POC_jws/ProcesoApertura/ProcesoApertura">
          <ns1:process>
               <ns1:tiposiniestro>A</ns1:tiposiniestro>
</ns1:process>
</soap:Body>
</soap:Envelope>
the composite works. But if i try to invoke with JAVA, with the code:
String payload5 = "<process xmlns=\"http://xmlns.oracle.com/POC_jws/ProcesoApertura/ProcesoApertura\">" +
     "     <tiposiniestro>A</tiposiniestro>" +
     "</process>";
String conversationId = UUID.randomUUID().toString();
NormalizedMessage nm = new NormalizedMessageImpl();
nm.addProperty(NormalizedMessage.PROPERTY_CONVERSATION_ID, conversationId);
Map<String,Object> payload = nm.getPayload();
payload.put("payload", pPayLoad);
nm.setPayload(payload);
service.post(pOperation, nm);
i get the following error:
Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to org.w3c.dom.Element
How can I send the message via JAVA API using the mediator in my composite?
Is there any important difference in the format between send a request with SOAP or JAVA?
Thanks in advance.

Talking about the dynamic rules in the Mediator, Oracle documentation says:
"As of now, only SOAP bindings are supported. There is a dummy SOAP binding in the composite.xml file. This endpoint is overridden by Mediator in runtime through NM property. So, outbound services can be called only over SOAP."
Is it valid for static rules as well? I means, how can i use Java API to invoke a Composite with a Mediator as first element? I always get the message:
+"java.lang.ClassCastException: java.lang.String cannot be cast to org.w3c.dom.Element"+
Thanks again
