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-007: Cannot acquire a database connection to process page.
Just getting started with XSQL with Oracle 8.1.7. Ran the
helloworld demo and got XSQL-007 error. How do I map
connection="demo" to a database service or SID name?I ran into somthing similar earlier. Checked an article off
ORAMAG, january 01 called 'Generating XSQL Server Pages'.
(http://www.oracle.com/oramag/oracle/01-jan/o11xml.html)
I found that if I verified the settings in the jserv.properties
file under Apache, and also verified the connetion info in the
XSQLConfig.xml file (Do a search) that you can eliminate the
issue. (I was using JDeveloper 3.2.3, and have some trouble with
JDev 9i, but I assume you can get some good info none-the-less
from this article).
Best of luck.

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 ;

Unable to get demo's working, "XSQL-007: Cannot acquire...."
I must be missing something simple but when I try to run the demo's I get the following error...
XSQL-007: Cannot acquire a database connection to process page.
Io exception: The Network Adapter could not establish the connection
My XSQLConfig file has the following connection information:

"jdbc:oracle:thin:@localhost:1521:ORCL"

9.0.4: XSQL-003/XSQL-007
My colleague is creating XSQL/XSL pages to return query results from an XML Schema in the DB. I have some JSPs that provide front-end UIs for these queries. We devoloped this in 9.0.3.3 and it worked fine. She sent the XSQL files and I included them into my project and called them from a JSP. Everything worked fine. I was forced to upgrade to 9.0.4 due to a bug and now when I call her XSQL files I get a connection not found error like follows:
Oracle XSQL Servlet Page Processor 9.0.3.0.0 (Production)
XSQL-004: Could not acquire a database connection named: iidev
XSQL-007: Cannot acquire a database connection to process page.
The connection iidev exists and I use it in the JSP that calls this xsql. I tried creating a new connection and a basic XSQL page like this:
<?xml version="1.0" encoding='windows-1252'?>
<page xmlns:xsql="urn:oracle-xsql" connection="TestConnection">
</page>
Which throws the same error.If you don't have an XSQLConfig.xml file, then XSQL won't work, so you must have one. :-)
JDeveloper will include one in your classpath at runtime automatically. It also manages to keep your XSQLConfig.xml up to date with your IDE's connections. However, here's probably what's happening.
You upgraded from 9.0.3 to 9.0.4
In 9.0.3, each time you defined a new database connection in the JDeveloper IDE, JDeveloper fixed up your XSQLconfig.xml file to match, so that there was a corresponding entry in the XSQLConfig.xml file for each connection you defined in the IDE.
When you migrate, even if you migrated all your settings, we don't migrate the XSQLConfig.xml file, so you're basically starting with a "fresh" one, which only has a "demo" connection defined for scott/tiger.
What I'd recommend is to:
1. Look at the top of your XSQL pages, and find the connection="XXXX" attribute in the file. It will be on the root element of the document.
2. You probably have a connection named XXXX under your Jdeveloper connections node.
3. Delete that "XXXX" connection in JDeveloper, and recreate a new "XXXX" connnection with the same information.
Doing this, JDeveloper will add the newly created "XXXX" connection to your XSQLConfig.xml file.
Then, it should work. -

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

XSQL-007 using Personal Oracle 8.1.6

Is your database SID the four upper-case letters 'ORCL' ?
The demos are looking for a connection named "demo" (unless you edited the demo directories' XSQL files, too).
Can you ping your "localhost" from a DOS box?<HR></BLOCKQUOTE>
How do I check whether the SID is ORCL and if not, can I change it? I did a default database installation.
When I look at the tnsnames.ora their is no mention of SID=ORCL - I don't know where to look or how to make the SID=ORCL. I added it after CONNECT_DATA =
CONNECT_DATA =
(SID=ORCL) <== added line
following example of another database, restarted database, but it did no good. Another aspect I don't understand - I can start SQLPLUS without specifying a database, but if I specify test or test.global, which is in the tnsnames.ora, it does not work. So what connect string is it using when I don't provide one? When I look in the Oracle home for the database, it says ORACLE_SID=test, but neither test or test.global works as connect strings.
I can ping local host.

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

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,
BartDid 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 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.
ThanksIf 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.
