XSQL / FOP generates NPE

Hi,
I am trying to generate a PDF with the help of a custom serializer and FOP 0.20.5 from XSQL page using Jdev 10g. While I am running the application, following runtime error is encountered. If I remove FOP, then the application comes up correctly.
Any help is highly appreciated.

XSQL/FOP to PDF

I am trying to generate a pdf using FOP within XSQL/XSL. The XSQL runs fine and the stylesheet appears to run fine with the exception that there is no pdf opened or saved (that I can see). Does the pdf get saved somewhere? Or should it open within adobe? Below is my code.

How to use Apache's FOP (getting NPE)

I'm trying to call out to FOP from a servlet to generate a PDF. Here's my code:
Driver driver = new Driver();
try {
driver.setOutputStream(response.getOutputStream());
} catch (IOException e) {
e.printStackTrace();
driver.setRenderer(Driver.RENDER_PDF);
Transformer transformer;
try {
transformer=TransformerFactory.newInstance().newTransformer(new StreamSource (xslStream));
transformer.transform(new StreamSource(xmlStream), new SAXResult(driver.getContentHandler()));
} catch (TransformerConfigurationException e) {
e.printStackTrace();
} catch (TransformerFactoryConfigurationError e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
The call to transform(...) causes a NullPointerException as such:
java.lang.NullPointerException
at oracle.xml.jaxp.JXTransformer.reportXSLException(JXTransformer.java:762)
at oracle.xml.jaxp.JXTransformer.transform(JXTransformer.java:335)
Any ideas what the problem might be?
Thanks,
--Voytek Jarnot

I fixed my problems with the following code, seems like oracle's xsl code is broke (at least in this context). Setting the javax.xml.transform.TransformerFactory to either "org.apache.xalan.processor.TransformerFactoryImpl" or "org.apache.xalan.xsltc.trax.TransformerFactoryImpl" works. I'm using the xsltc version for performance reasons.
Of course, the whole point of the api is to allow vendors to plug in implementations, and for me not to worry about which specific implementing classes are being used. I'm breaking that abstraction here, but at least it works...
<pre>
static {
//Set the TransformerFactory system property to generate and use translets.
//The setting for the Xalan Transformer "org.apache.xalan.processor.TransformerFactoryImpl"
String key = "javax.xml.transform.TransformerFactory";
String value = "org.apache.xalan.xsltc.trax.TransformerFactoryImpl";
Properties props = System.getProperties();
props.put(key, value);
System.setProperties(props);
</pre>

PDF generation with FOP throws NPE

Hi,
Stack trace
at oracle.xml.jaxp.JXTransformer.reportXSLException(JXTransformer.java:769)
at oracle.xml.jaxp.JXTransformer.transform(JXTransformer.java:342)
I'm using standard Java 1.4 API calls to create a PDF document from a DOM with Apache FOP 0.20.5.
The servlet is deployed to Oracle 10g Application Server 9.0.4.0.0. With Tomcat 4.1.30 the same code executes without exceptions
Because I have to port our web application to Oracle for a new customer it is important for me to get this fixed soon.
Thank you
Eckard

Light at the end of the tunnel: It seems to work when FO and PDF generation are separated. Until now the DOM was piped into FOP who internally created the FO from SAX events and then seems to parse it again to create PDF.
I separated the two steps: There is no problem in FO generation, but due to a namespace problem subsequent parsing fails
("org.apache.fop.apps.FOPException: null:2:10 Root element is missing the namespace declaration: http://www.w3.org/1999/XSL/Format")
Now the correct exception comes up. Whether FOP SAX event listener is buggy or XML parser's error handling has a problem, I don't know
Thank you anyway
Eckard

Can we send an FOP generated PDF by email in PL/SQL code?

Hi All,
I have the FOP PDF generation of a report. We can "Save As" to the hard drive and then manually email it to someone by attaching it to the email.. normal..
Can we click a button on the report, save the report as PDF and send it through htmldb_send emailing?
I would think this would be in the htmldb_fop_render.jsp file.. not know JSP much.. has anyone done it? or are the tools available to JSP?
Thanks, Bill

This can be done with a little PL/SQL coding.
Presuming you are using this guide:
http://www.oracle.com/technology/pub/notes/technote_htmldb_fop.html
I would look at:
1. Changing pdf_GrabXML to simply return your XML call into a page item without posting it,
2. Use the OWA_UTIL PL/SQL package to post your request, and handle the retrieved PDF.
3. Send the email with the UTL_SMTP PL/SQL package, as I don't the APEX mail libraries expose attachment functionality.
I will try to put an example together tomorrow if I get chance.

Error using XSQL to generate RSS feeds on Unix

I`m using an XSQL file used with a stylesheet to render an RSS 2.0 feed.
RSS readers can pick the feed up successfully when I used a Windows based Oracle Application server installation but not when it was migrated to a Unix based server.
Both servers do successfuly render the RSS feed into Internet Explorer as raw XML which looks identical.
Any ideas?

Check the content type of the response comming from your Unix server. There may be a different content type value for one of the HTTP header, which have some impact on your RSS reader.
Using FireFox is another way to see if there are subtille differences in the responses that IE does not detect.
Hope this helps,
Eric

Xsql and fop - showing blank pdf in browser

I am using the following configurations:-
Apache 1.3.27 webserver,
Apache Jserv 1.1.1
xdk java version 9.2.0.5.0
fop 0.16.0
Adobe acrobat 4.0
All other examples are working .
The problem is
when i am trying to access ../xsql/fop/emptable.xsql
i am getting blank page (nothing is coming on the
browser). But I think browser is loading acrobat
because i can see the accrobat's flash page for a
second.
I think nothing wrong with acrobat , because i used to
see pdf files from internet
thanks in advance

XSQL und BEA Weblogic ERROR:XSQL-013

We develop an web-application using XSQL to generate XML, which is further transformed via XSL to HTML or PDF.
As IDE we use JDeveloper 9.0.3.1.
Running and debugging in JDeveloper works fine.
We deploy the application as war-file on bea weblogic 7.2.
When starting the xsql-servlet / calling the xsql file we get the following error:
Oracle XSQL Servlet Page Processor 9.0.3.0.0 (Production)
XSQL-013: XSQL Page URI is null or has an invalid format.
XSQLConfig is located in:

Whats wrong or missing?
Thanks

Trying to check whats going on within the XSQL-Prozessor we tried the programmatic approach.
First step is to call XSQL from within an action /jsp .
<%
String baseUrl = request.getScheme()
+ "://"
+ request.getServerName()
+ ":"
+ request.getServerPort()
//+ "/"
+ request.getContextPath()
+ "/"
URL pageUrl = new URL(baseUrl+"report/untitled2.xsql");
XSQLRequest req = new XSQLRequest(pageUrl);
PrintWriter of = new PrintWriter( new FileOutputStream("./report.xml"));
PrintWriter ef = new PrintWriter( response.getOutputStream());
Hashtable params = new Hashtable(0);
req.process(params, of, ef );
%>
But still there is an error.
This time we got:
Oracle XSQL Programmatic Page Processor 9.0.3.0.0 (Production) XSQL-005: XSQL page is not well-formed. XML parse error at line 2, char 1 Expected 'EOF'

XSQL has nothing to do with ADF directly. You access XSQL via a Servlet, so you could deploy the XSQL servlet and access it via an af:goLink or af:goButton.
Since XSQL is part of the Oracle XML Developer Kit, if you have questions about how to write the report itself, {forum:id=157} is probably the best forum to use.

How to Deploy FOP demo example

I have been trying to get the FOP demo example which comes with XSQL Demos in Oracle_home\xdk\demo\java\xsql\fop to work. I want to do something similar for one of your projects (have a .xsql file with .xsl file to transform it to fo using default serializer class defined in XMLConfig.xml). I assume that I can do that?
I put the two files, emptable.xsql and emptablefo.xsl, in a web application in JDeveloper 10.1.2 build 1811. I got them to run in JDeveloper 10.1.2 with the embedded OC4J Server after putting the following libraries in tools -> Embedded OC4J Server Preferences, Global -> Libraries.
fop.jar
batik.jar
avalon-framework-4.0.jar
logkit-1.0.jar
from fop-0.20.3a-bin.tar.gz.
I want to deploy this application to Oracle 10g AS 10.1.3. I put the above libraries in the classpath by selecting: Tools->Project Properties, Profiles->Development Libraries and also xsqlserializers.jar which was in the JDeveloper Home/lib.
I also created a orion-web.xml file and set search-local-classes-first="true".
That did not help either. I created a .ear file and deployed from Application Server Control, OC4J home.
I get the following error when trying to display emptable.xsql. My deployment works (if I leave out the xml-stylesheet line in the .xsql file then I get the proper data in the webpage.).
Oracle XML Developers Kit 10.1.3.0.0 - Production
XML-25022: Cannot load serializer class oracle.xml.xsql.serializers.XSQLFOPSerializer
Is there any recent FOP examples on how to set an FOP applicaton? Or documentation?
I have read Integrating FOP with Oracle JDeveloper. I don't wish to do it this way that is write my own FOP.java but just use default FOP serializer class?

I followed the second article:
http://technology.amis.nl/blog/?p=1182
I do it to run in JDeveloper 10g 10.1.3 but now trying to deploy it to Oracle 10g AS 10.1.3, I get the following:
Oracle XML Developers Kit 10.1.3.0.0 - Production
XML-25022: Cannot load serializer class oracle.xml.xsql.serializers.XSQLFOPSerializer
I downloaded, fop-0.20.5-bin.zip. And created the XSQLFOPSerializer class in the XSQLModel project. I gave my package name a different name then the name, oracle.xml.xsql.serializers, which was in the article. I put my class name in the XSQLConfig.xml file. This class is included in the War deployment profile. So why would I be getting the above error?
So do I need to make my class the name, oracle.xml.xsql.serializers.XSQLFOPSerializer?

xsl:element missing node problem

I was reading Re: re:how to use Apache's FOP (getting NPE) on the Oracle forums and noticed Steve M. said something about not being able to find nodes that <xsl:element> has created. I am currently having this problem when doing double transformations on documents. We would like to eliminate redundant style sheets but removing the table name prefix from our column names.
ex:
SZRADAP_PIDM and SZBRECR_PIDM have the same data and the rest of the columns in the two table are named in the same fasion. I have a simple style sheet that removes the table name prefix.
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xhtml" indent="yes"/>
<xsl:template match="node()[contains(name(), '_')]">
<xsl:element name="{substring-after(name(), '_')}">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
It works just fine but I would then like to include this .xsql in another .xsql for transfomation by a stylesheet that looks for the table non-specific tags. As was stated in the article I cannot find the nodes that have been created by the <xsl:element> function. I cannot readily use xsl:copy so I seem to be stuck. Any help or suggestions would be much appreciated.

Well I seem to have found the problem ... I was using an old version of the XDK where this was an apparent bug. I've upgraded to the latest production XDK and it's all fixed.

David,
You are right, theer are some changes incorporated in the latest MLR # 16 on the configurations files and on the dehydration store metrics(such as performance, fields,..).
However, I would not suggest to continue working on olite, even for Development/Test purposes as you might get stuck with strange errors...and the only solution would be to re-install SOA Suite if your olite gets corrupted. There might be ways to gets your olite back to position, but trust me..its not so simple.
Also, when you develop and stress test all your testcase scenarios in an TEST Adv installation, its simple to mimic the same in actual production box, as you exactly know its behavior.
So, go for a brand new SOA 10.1.3.4 MLR # 5 (or) 10.1.3.3.1 MLR # 16 SOA Suite Advanced installation with Oracle DB 10.2.0.3 as its dehydration store.
Hope this helps!
Cheers

How to handle multiple exception types in JSF 2?

I'm trying to handle multiple exception types in JSF2, including a default error page for any unexpected exception types. The problems I'm having are:
1) ViewExpiredException is handled only when no generic exception handler is specified
2) "Regular" exceptions like NullPointerException are never handled
My managed bean:
@Named
@SessionScoped
public class MyController implements Serializable {
/* A method that does nothing */
public void doNothing() {
    //do nothing
/* Generate a null pointer exception on purpose */
public void generateNpe() throws NullPointerException {
    Object x = null;
    x.toString();
My test page to generate the exception:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core">
<h:head>
    <title>Test page</title>
</h:head>
<h:body>
    <h:form>
        <h:commandButton id="button1" value="do nothing" action="#{myController.doNothing}" />
        <h:commandButton id="button2" value="generate NPE" action="#{myController.generateNpe}" />
    </h:form>
</h:body>
</html>
My web.xml:

<error-page>
    <exception-type>java.lang.NullPointerException</exception-type>
    <location>/error/error003.jsf</location>
</error-page>

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/error/error002.jsf</location>
</error-page>

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/error/error001.jsf</location>
</error-page>My questions are as follows:
1) How can we handle "regular" java exceptions like NPE?
2) How can we define a catch-all for unexpected exception types, while still respecting specific exception handlers for VEE, etc?
Thanks,
Benjamin

Is your data model right? If you are adding in one and deleting in another it sounds to me more like a process that an entity, in which case you may revisit your data model and simplify it, add in a session bean with the process method to co-ordinate between the two.
However, if you want to map multiple different tables within a single entity bean it is possible and just part of the mapping. How you actualyl specify it depends on which implementation you are working with.

Problem writing a XSLT to convert XML in desired format from a table having self join

Hello,
I have to write a style sheet to convert XML generated from XSQL into a different format. The query that I have is as follows.
select LEVEL depth,
'H' || hierarchy_id id,
name,
nvl2(parent_id, 'H' || parent_id, 0) parent_id,
CURSOR(select LEVEL depth,
'H' || hierarchy_id hid,
name hname,
nvl2(parent_id, 'H' || parent_id, 0) hparent_id,
decode(system_id, NULL, '0', 'S' || system_id) formatted_system_id,
system_id
from hierarchy
where parent_id = h.hierarchy_id
and system_id is not null
) as systems
from hierarchy h
where system_id is null
start with parent_id is null
connect by prior hierarchy_id = parent_id
The hierarchy table has a self join to itself. The selfjoin is on the hierarchyid and the parentid fields which is evident from the query.
Here the hierarchy table contains the parent system and also the child systems underneath. The problem is that the no. of levels that it can go deep is not fixed. The output of this in sqlplus is as follows.
Depth Hierarchyid, name parentid
1 h1 xxx <null>
2 h2 bbb h1
3 h3 ccc h2
<Cursor for systems>
hid hname hparentid formatted_system_id systemid
h4 ccc h2 s1 1
h5 ccc h2 s2 2
<Back to original data>
Depth Hierarchyid, name parentid
2 h6 ddd h1
2 h7 eee h1
The desired output required from the stylesheet is as follows
<h id=h1 name=xxx>
<h id=h2 name=bbb parentid=h1>
<h id=h3 name=ccc parentid=h2>
<h id=h4 name=fff parentid=h3 systemid=s1>
<h id=h5 name=ggg parentid=h3 systemid=s2>
</h>
</h>
<h id=h6 name=ddd parentid=h1/>
<h id=h7 name=eee parentid=h1/>
</h>
Could some one guide me as to how to get this. I did write a stylesheet which gives me the following output.
<h id=h1 name=xxx>
<h id=h2 name=bbb parentid=h1/>
<h id=h3 name=ccc parentid=h2/>
<h id=h4 name=fff parentid=h3 systemid=s1>
<h id=h5 name=ggg parentid=h3 systemid=s2>
</h>
<h id=h6 name=ddd parentid=h1/>
<h id=h7 name=eee parentid=h1/>
</h>
As you can see I am missing the closing of the tag on the 7th line in the desired format. I have written the following stylesheet.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>

<xsl:template match="HIERARCHY">
<HIERARCHY><xsl:apply-templates/></HIERARCHY>
</xsl:template>

<xsl:template match="HELEMENT">
<xsl:choose>
<xsl:when test="PARENT_ID=0">
<helement id="{ID}" name="{NAME}" parentid="{PARENT_ID}"/>
</xsl:when>
<xsl:when test="PARENT_ID!='0'">
<helement2 id="{ID}" name="{NAME}" parentid="{PARENT_ID}">
<xsl:for-each select="SYSTEMS/SYSTEMS_ROW">
<helement3 id="{HID}" name="{HNAME}" parentid="{HPARENT_ID}" systemid="{FORMATTED_SYSTEM_ID}">
</helement3>
</xsl:for-each>
</helement2>
</xsl:when>
<xsl:otherwise>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Is there any way of achieving this. Any help would be appreciated. I am using XSQL to generate first the basic XML output and then applying stylesheet to achieve the desired output.
Sincerely,
D
