XSQL-022 error

Hi,
I try to create a pdf with the xsql -servlet (v1.0.4) and FOP 0.14.
When I don't use the serializer="FOP" in my <?xml-stylesheet?> processing instruction, I get an XML-file with <fo-root> as the root-element. Looks fine.
When I include the serializer="FOP" in my <?xml-stylesheet?> processing instruction i get the following error:
"XSQL-022: cannot load serializer class oracle.xml.xsql.serializers.XSQLFOPSerializer"
I have used a default installation of the xsql-servlet in c:\xsql, Java in c:\jdk1.3, Apaches FOP in c:\xml\fop. The file xsql-wtg.bat is changed to this configuration.
Everything else is working fine, so what is wrong with the set-up.
Steve,
if you read this I also have a request: could you publish all xsql-error messages on OTN? Your book only lists xsql-errors up to XSQL-017, the xsql-servlet documentation doesn't describe the errors at all.
Thanks to all,
Bart

Did you uncomment the line in the xsql-wtg.bat that includes the:
.\xsql\lib\xsqlserializers.jar
FOP_HOME\fopXXX.jar
FOP_HOME\lib\w3c.jar
in your classpath?
I'll post the error messages.

XSQL-022 error on using FOP - serializer class not found; urgent!

Hi all,
currently using XDK 9.2.0.1.0. On trying to invoke Apache FOP serializer I just get the following error message:
XSQL-022: Cannot load serializer class oracle.xml.xsql.serializers.fopserializer
and I really don't know why....
Running XSQL Servlet within Tomcat 4 Engine, but error pops up using both, Tomcat way and/or just the commandline invoker xsql.bat.
Generally XSQL Servlet is working correctly.
My classpath setting contains:
xmlparserv2.jar; batik.jar; classes12.jar; fop.jar; fopserializer.jar; oraclexsql.jar; sax2.jar; xalan-2.0.0.jar; xalanj1compat.jar; xerces-1.2.3.jar; xschema.jar; XSQLConfig.jar; xsu12.jar
The serializer being redefined in XSQLConfig is just:
<serializer>
<name>FOP203</name>
<class>oracle.xml.xsql.serializers.fopserializer</class>
</serializer>
This is because of using FOP 0.20.3, so having my own serializer class due to API change in FOP 0.20.x; my fopserializer is looking like that:
package oracle.xml.xsql.serializers;
import org.w3c.dom.Document;
import java.io.PrintWriter;
import oracle.xml.xsql.*;
import org.apache.fop.messaging.MessageHandler;
import org.apache.fop.apps.*;
import java.io.*;
// FOP 0.20.3 Serializer implementation for XSQL
public class fopserializer implements XSQLDocumentSerializer
private static final String PDFMIME="application/pdf";
public void serialize(Document doc, XSQLPageRequest req) throws Throwable
try
Driver FOPDriver = new Driver();
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
MessageHandler.setOutputMethod(MessageHandler.NONE);
FOPDriver.setupDefaultMappings();
req.setContentType(PDFMIME);
FOPDriver.setOutputStream(req.getOutputStream());
FOPDriver.render(doc);
catch (Exception e)
e.printStackTrace(System.err);
In my XSQL file I'm using the following PI:
<?xml-stylesheet type="text/xsl" href="listemps.fo" serializer="FOP203"?>
Any suggestions what is wrong in here ?
Can't use the original xsqlserializer.jar either - same error.
Thanks in advance
Jochen

Hi Jochen,
I'm working with Tomcat 4.0.3, FOP 20.0.3 and XDK 9.2.0.1.0, too.
I've copied all the jar-files into tomcat/common/lib. I think that you can't use the MessageHandler in fop20.0.3. I'm using the following serializer:

// Setup logging
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();

LogTarget target = null;
target = new StreamTarget(System.out, formatter);
hierarchy.setDefaultLogTarget(target);
Logger log = hierarchy.getLoggerFor("fop");
log.setPriority(Priority.INFO);
FOPDriver.setLogger(log);
// Then set the content type before getting the reader/
env.setContentType(PDFMIME);
FOPDriver.setRenderer(FOPDriver.RENDER_PDF);
FOPDriver.setOutputStream(env.getOutputStream());
FOPDriver.render(doc);
catch (Exception e) {
// Cannot write PDF output for the error anyway.

XSQL-022: Cannot load serializer class oracle.xml.xsql.serializers.fop203

Hi,
I' have used Tomcat 4.0.3 with XSQL Servlet 9.2 for about a half year. All is working fine. When I now change to 4.1.18 the most things are also working fine. The are to problems:
1. I have to save the XSQLConfig.xml in a jar file.
2. My fop serializer doesn't work any longer. I'm getting all the time the following error: XSQL-022: Cannot load serializer class oracle.xml.xsql.serializers.fop203.
I'm using the XDK 9.2.0.4 with jsdk 1.4.1 and tomcat 4.1.18 on Redhat Linux.
Has anyone had have the same problem? Has anyone a solution for this problem?
Regards
Uwe

Does the XSQLSampleSerializer exhibit the same problem?
That is, can we rule out the fact that it's related at all to FOP?
If you browse the following page, does it work?
<?xml version="1.0"?>
<?xml-stylesheet serializer="java:oracle.xml.xsql.serializers.XSQLSampleSerializer"?>
<foo-with-java/>This sample serializer should be in your xsqlserializers.jar file.

XSQL-003 Error with jakarta-tomcat-4.0.3

I am trying to set up the XSQLServlet on JBuilder7 using jakarta-tomcat-4.0.3 as the development server.
I downloaded and carefully follwed the installation instructions for Tomcat 3.1 and 3.2 although the bat files have changed considerably. Set classpath in setclasses.bat and prescribed in instructions. Setup a context in server.xml for /xsql and setup a web.xml file to map oracle-xsql-servlet to *.xsql. Also tried mapping to *.xsql in web.xml for my application, but I continue to get the XSQL-003 error; "failed to find XSQLConfig.xml in the server classpath". I checked the discussion forums and tried jarring the XSQLConfig.xml file and set that in the server CLASSPATH. Still no luck.
My question: Are there any installation instructions for installing the XSQLServlet on Jakarta Tomcat 4.0.3?
Tomcat can't find the XSQLConfig.xml file or there is some other problem that is throwing this exception.

Hey man, i have the same problem, what should I do?
I can`t define the classpath when I run the server as service, but it works when i run manually starup.bat, because there i have defined the classpath.
Please, give me an advice
Thanks...

Xsql-007 Error

Oracle 9.0.1 on Solaris 9, SPARC hardware. XDK is the one that came on the CD with the original install.
Had XSQL queries working fine, then had to change the nodename of the machine when we got a domain.
Now all DB queries return "XSQL-007: Cannot acquire a database connection to process page.
Io exception: The Network Adapter could not establish the connection"
Apparently the Servlet doesn't get it's DB connection from Localhost, but from the nodename defined in /etc/nodename.
Anybody know how to redirect from the old nodename to Localhost or the new nodename? Also, does anybody know where all the XSQL error messages are documented? I've searched OTN, no luck.
Thanks,
Ben

Thanks for your reply!
You got me on the right track! TNSNAMES.ORA had the correct hostname, but I still had the wrong hostname in $ORACLE_HOME/network/admin/listener.ora.
What had me confused was the fact that Windows SQLPlus clients could connect just fine but the server couldn't find it's own database.
Thank you!!!
Regards,

XSQL work with TomCat4.04/JBoss 3.0.1 bundle? xsql-013 error

Hi, does anyone have any luck to make xsql servlet in xdk_java_9_2_0_3_0 work with Tomcat/Jboss?
Tomcat here is 4.0.4.
I tried but find the following message:
Oracle XDK Java 9.2.0.3.0 Production
XSQL-013: XSQL Page URI is null or has an invalid format.
I also install in on tomcat 4.0.4 standalone.
At lease it showed that it can't find my database connection 'demo'.
So I am not sure what is the problem any more.
Thanks

If you expand the xsqldemos.war file, does it work ok?
Until xsql 10i release, pages from an unexpanded WAR file won't work. No. I extracted the war file out of the ear file and only deploy the war file.
And try to access http://host:8080/xsqldemos/index.html
I got the same error: "XSQL-013: XSQL Page URI is null or has an invalid format."
However, it works with JBOSS 3.0.0 Tomcat 4.0.3.

I'm trying to write a servlet in jDeveloper to take the XML document produced by XSQLRequest and an XSL (FO) file and produce a PDF response. So far I am unable to get jDeveloper to be able to find the Apache FOP jar files.
How did you get jDeveloper to be able to find the Apache FOP jar files?
Thanks in advance,
Tom.

Xsql giving error

I am using an html link to call a xsql file
at the first instance it is accessing the database but after that it is giving an error as "Cannot view Xml input using stylesheet" XML Document must have a top level element.
I have not used stylesheets so is the problem for that or is it necessary to use stylesheet while using XSQL Servlet Utility.

There's no requirement to use stylesheets.
It probably means that your page is returning no data.

FTR_TRD 022 Error message when I try to settle SWAP transaction which was reversed previously

Hello Gurus!
I've got a problem with settlement of SWAP transaction.
The situation:
1) I created Cross-curr.interest Swap transaction. Product type is the copy of "62B Cross-curr.int.rate swap (CCS) SWAP"
2) Made 'Settle' for it.
3) Made 'Reverse' for it.
4) After that I try to re 'Settle' transaction. Error message appears for the flow 1125
Unable to determine the TRD business transaction for flow 1125 31.08.2014 + 35.000,00
Message no. FTR_TRD022
The same message error appears on 'Change' of this transaction.
I don't have such problems with other OTC transactions.
What should I do with it. I thought that it is SAP program error but I didn't find any suitable Notes.

Hello Jyoti,
thank you for reply!
I've got processing category for my transaction category = '00002 With Settlement'.
So then I reverse the transaction activity is changed from '2 Contract Settlement' to '1 Contract'
What do you mean 'setting for activity reverse to settle. Generally we define activty 10 to 20' ??
Where can I customize ??

What DB version? What does your table look like (datatype-wise for the columns) ?

XSQL-007 and list of XSQL error codes.

I have a situation where I need to replay a request if I cannot acquire a database connection, and to not replay a request otherwise. Is the XSQL-007 code the only code that deals with database connections?
XSQL-007: Cannot acquire a database connection to process page.
Do you have a published list of XSQL codes? Is there a method in java code to generate the full list of XSQL codes? For example to get a list of database error codes, one can in PL/SQL use:
set serveroutput on size 2000
begin
for i in 1..9999 loop
dbms_output.put_line ( sqlerrm(-i) ) ;
end loop ;
end ;
Steve.

There's not a way to loop through the errors in Java. Here's the list.

Error while running a sample XSQL from XML bible book from Steve Muench

I am running the sample XSQL code from Chapter 03, which deals with exporting XML and transform into SQL statements. I'm using JDeveloper and I believe I've setup libraries and HTML root directory etc. I'm getting the following error:
XSQL-011 Error processing XSLT stylesheet.

Can I get some help in fixing this error?
Thanks a lot,

Hi,
This is the example I took from Steve Muench's book.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
</xsl:template1>
</xsl:stylesheet>
As you can see, I do have the version=1.0 attribute. Why is it complaining still?

XSQL/XSL help (iPlanet): Error processing XSLT stylesheet

hello-
i am running XSQL and XSL pages on an iPlanet web server and i am receiving the following error:
XSQL-011: Error processing XSLT stylesheet: /xslt/page/xsl_page.xsl
XSL-1002: Error while processing include XSL file (\xslt\util\other_xsl.xsl (The system cannot find the path specified)).
here's the deal: other_xsl.xsl (the one it says it can't find) is there in the right place, but the web server is not looking from the document root (which IS set correctly on the web server). it is looking for the file starting at the current directory.
for example, the server is processing /xslt/page/xsl_page.xsl. it is then looking for the include file using this path: /xslt/page/XSLT/UTIL/other_xsl.xsl --- instead of the correct /xslt/util/other_xsl.xsl.
the include statement uses the full path starting from the web root (<xsl:include href="/xslt/util/other_xsl.xsl"/>)
any help would be appreciated.

thanks for the response. the /xslt/util directory is browsable by the web server, and using relative paths does work (that is one of the ways i discovered what was going on in the first place), but i am rebuilding a machine and redeploying an exisiting application-- the intention is to not re-write any code.
the part that is most confusing is that the current code/directory structure works on the current box, but not on my rebuilt box. i have gone through every config file with a fine tooth comb. it appears that the current box and my build are set up exactly the same-- but, like i said, on one it reads the include-path from the document root, on the other from the current directory.
so confusing.
