Jservlet - OAS 4.0.8

Hi all,
Has anyone worked with 'Jservlet' cartridge on OAS 4.0.8? Is
this a new feature of OAS 4.0.8 ? If so could you please give me
details on the development environment.
Should I use JSDK2.1 to develop servlets and can these servlets
be put on the OAS and run using a 'JServlet' cartridge? I am
familiar with pl/sql and jweb cartridges. Could someone give me a
fair idea on this and how it differs from jweb cartridge....where
can i find documentation on it.?
Thanks in advance for your time

Hi
JServlet is the new in OAS4.0.8. You can use JDeveloper to
develop servlets. JDeveloper provides complete support to
develop, test and debug servlets.
Once you have done this you can deploy them to OAS or any other
mid tier.
For more OAS documentation take a look at
http://www.olab.com/doc/index.htm

hi,
Are you using forms and reports???
If yes then go
$ORACLE_HOME\forms\j2ee\orion-web.xml
Check for the line
<context-param-mapping name="configFileName">
/oraApps/oraclebi/forms/server/formsweb.cfg
</context-param-mapping>
(/oraApps/oraclebi/ is the value for my ORACLE_HOME.)
Make sure that the configFileName is pointing to a valid file (formsweb.cfg by default) and that the directory path is correct.
This should solve your problem
Regards
Fabian

OAS 4.0.8.1 - JServlet Cartridge - error OWS-04769

I'm trying to run servlets under the JServlet Cartridge of OAS. My servlet uses the HttpSession class to track sessions. After receiving requests from 3 clients the servlet stops running with the following messages in wrb.log:

08-15-2000 14:22:56 484025 darkstar `Broker` 5786 1 0x10fff `OWS-04760: Disable Host darkstar for Cartridge Secure_Apps/Login. `
08-15-2000 14:22:56 524139 darkstar `Broker` 5786 1 0x10fff `OWS-04759: No host is available to create Cartridge Secure_Apps/Login. `
How do I increase the number of cartridge instances? Or how else can I work around this problem.
Thanks.

I increased the severity level for logging to 15 for the Cartridge configuration
in the OASManager.
It says init method did not return. For my init method I have that following :
public void init(ServletConfig config) throws ServletException
super.init(config) ;
All the above was generated by the Servlet Wizard.
Below if the level 15 trace information :
OWS-10911: Throwing exception for reason: wrkwExecute: Exec callback returned WRB_ERROR `
OWS-10833: Cartridge HelloServlet/HelloCart init runtime callback did not return WRB_DONE `
OWS-10911: Throwing exception for reason: wrkwfInit:Error in wrkwfInit `
OWS-10911: Throwing exception for reason: wrkwfStartOrig:Error at creation time `
OWS-10911: Throwing exception for reason: wrkwfStart: Cartridge Instance factory creation failed. `
OWS-10803: Cartridge instance factory for HelloServlet/HelloCart not intialized `
OWS-10911: Throwing exception for reason: No Carrtridge Instance Factories Initialized Properly `
OWS-10821: Application HelloServlet failed to deregister with the name server `
OWS-10850: Cartridge Server HelloServlet received exception IDL:oracle/OAS/Cartridge/InitFailed:1.0 while deregistering
Can anyone advise why and what needs to be
done to fix this ??
Please help.

XML parser in JServlet cartridge [OAS 4.0.8.1]

i'm deploying XML-aware servlets on Oracle Application Server 4.0.8.1 using JServlet cartridge.
I wondered if anyone did this before, especially in the light of rather crippled JVM of OAS [JDK1.1.6 only].
any input would be appreciated.
thanks,
alan <[email protected]>

There are no known issues with the configuration. JDK's before 1.1.8 (for sure, 1.1.7) have character set conversion problems between UTF-8 and other character sets, so if you are doing that, you may have issues.
OAS 4.0.9 is 1.2.x based.

OAS 4.0.8.1 JServlet: Extra path info not implemented?

Didn't Oracle implement extra path info for servlets? According to the Java Servlets spec it should be possible to invoke a servlet with a URL like http://host/servlets/MyServlet/index.html where /index.html would be accessible through the getPathInfo() method of the servlet and the translated path would be accessible through the getPathTranslated() method.
Trying the sample servlet SnoopServlet delivered with OAS 4.0.8.1 through http://host/servlets/SnoopServlet/index.html OAS tries to load a class called ...\SnoopServlet\index\html and throws a ClassNotFoundException (naturally).
Is this a bug or didn't Oracle implement extra path info?
Thanks.

I posted the same question some time ago but I didn't get an answer. BTW Oracle JServlet Cartridge documentation states that extra path is accessible through the getPathInfo(). Here is excerpt from the Invoking JServlet cartridges document:
To invoke a JServlet cartridge, the URL must be in the following format:
http://hostname[ ort]/virtual_path/java_class_name[path_info][?QUERY_STRING]
where:
hostname specifies the machine where the application server is running.
port specifies the port at which the application server is listening. If omitted, port 80 is assumed.
virtual_path specifies a virtual path mapped to the JServlet cartridge.
java_class_name specifies the Java class to run. This class must contain an entry point method. If a query string is included in the URL then there must be a doGet() method.
path_info provides additional path information for the servlet. The path can be accessed from the servlet using the HttpServletRequest.getPathInfo() method.
QUERY_STRING specifies parameters (if any) for the Java class. The string follows the format of the GET method. For example, multiple parameters are separated with the & character and spaces are replaced with the + character. If you use HTML forms to generate the string (as opposed to generating the string yourself), the formatting is done automatically for you.
But I couldn't make it work as described in documentation.

OAS JServlet Cartridge and PathInfo

OAS 4.0.8 documentations states that to invoke a JServlet cartridge, the URL must be in the following format: /virtual_path/java_class_name[path_info][?QUERY_STRING]]http://hostname:port]/virtual_path/java_class_name[path_info][?QUERY_STRING]
For example, if a browser sends the following URL: http://myhost/my_virtual_path/myServlet/myPathInfo JServlet cartridge is supposed to recognize myServlet as a servlet class and myPathInfo as a Sting returned by getPathInfo() method.
But I couldn't make it work that way. I was able to invoke myServlet sending just http://myhost/my_virtual_path/myServlet. But every time I add myPathInfo to the request URL the JServlet cartridge fails to invoke servlet with myServlet/myPathInfo.class not found error message. Am I missing somethig? My phisical path associated with the virtual directory points to the package containing servlet class and some other classes. Actually that servlet is working fine on Apache server and I am in process of porting it to OAS.

OAS 4081: How to use a DAD with JServlet cartrige and JDBC?

i try to open a db connection in the jservlet cartdige via jdbc, using the following url-format in the getconnection() method:
"jdbc:oracle:jts7:@<myDAD>"
i get an sqlexception "sub protocol not specified".
the release notes of version 4081 say that something has changed in the jdbc/jts drivers from version 407 but they don't say what.
does anybody know?
remarks:
1) declaring the dad and the jservlet cartdige transactional or non-transactional in the oas manager seems to have no effect on this problem
2) connection without the jts and the URL "jdbc:oracle:oci8/thin:@<tnsname>" works fine
null

Hi Amit,
Sounds like a good idea but then you would need an external db and update the table in a thread safe way !.
Regarding your question as to how to work with global variable please refer https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/1352. [original link is broken] [original link is broken] [original link is broken]

Jservlet Deployment in OAS

Hi,
When we deploy a HTTPServlet to OAS, we can deploy it only as JServlet and after registering the servlet, if we look into the wrb.app, it says that the Execution string is wrks -s.
Because of this, when my applet communicates with the servlet and when the applet expects an object to be sent by the servlet, the applet gives a java.io.EOFException and in the web server I am able to see a new blank window popping up with the title 'wrks'.
What should the Exec String be set to in OAS for servlets?
Has anybody come across this problem? If so, can you pls tell me how to solve this?
Thx
SUdha

Hello ,
You do not explicitly need to set the Execution string for the jservlet cartride.
First ensure that the servlet by itself executes fine & is accessible from a browser.
Once this works, then you could access the servlet from a applet, using the java URL class.
Attaching a doc below which explains how to access Cartridges from a Java program
You are invoking a Oracle Application Server Cartridge to access the database
using a Java program.
From a Java program (Applet/Application), you could access database using JDBC
drivers. Invoking cartridges(PL/SQL, JAVA) to access the database from a Java
program, makes sense if,
a. The code required to access the database has already been written using
a cartridge.
b. The majority of the job done by the Java application is non-database.
c. You need to access database without a JDBC Driver and without using
Sql*Net(If you are using OCI Based JDBC drivers)
The major advantage of the above is code reusablity.
This is acheived by using the URLConnection class defined in the java.net
package, which allows the opening of a URL, and reading in the contents of the
URL. Accessing cartridges from a Java program is similar to accessing CGI
scripts from a Java program. Parameters can be passed to a CGI script using
the GET or the POST method. In the GET method, parameters are passed along with
the URL.
Example: http://oraclebl.oracle.com/cgi-bin/get_data?deptno=10
In the POST method, the parameters are passed to the Standard input of the CGI
script, which points to the data sent from the browser. The POST METHOD is
quickly making the GET METHOD obsolete because it's more versatile and has no
limitations on the amount of data that can be sent through the connection.
Given below is a example of a Applet accessing the PL/SQL cartridge to retreive
data from the database. The same concept could be used to access any other
cartridge(such as a Java cartridge) working on the HTTP protocol.
PL/SQL procedure accessed:
create or replace procedure get_emp_data(deptno in number) as
cursor c1(dept in number) is select empno, ename from scott.emp where deptno=dept;
begin
owa_util.mime_header('text/plain');
for i in c1(deptno) loop
htp.p(to_char(i.empno)| |' '| |i.ename);
end loop;
end;
Applet code accessing the above procedure using the PL/SQL cartridge.
package package4;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import java.net.*;
import java.io.*;
public class Applet1 extends Applet {
Button button1 = new Button("Query Details"); /* Button to Query emp details */
TextField deptno = new TextField("",10); /* TextField to get the deptno */
FlowLayout flowLayout1 = new FlowLayout(); /* Initialize a Flowlayout class */
TextArea empDetails = new TextArea("",10,40); /* TextArea to display emp details queried */
public void init() {
setLayout(flowLayout1);
setSize(new Dimension(400, 329));
add(deptno);
add(button1);
button1.addActionListener(new button_listener(this));
add(empDetails);
void button1_actionPerformed(ActionEvent e) {
String t1 = empDetails.getText() ;
empDetails.replaceRange("",0,t1.length()); /* Initialize empdetails to "" */
try
URL url = new URL("http://winnt-nsc.in.oracle.com:8888/web_apps/plsql/get_emp_data");
/* Initialize the URL pointing to a PL/SQL cartridge */
URLConnection connection = url.openConnection();
connection.setDoOutput(true); /* Enable Output to the above URL Connection stream */
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.print("deptno="+deptno.getText());
/* Send the deptno value to the output stream. This would be read by the cartridge
Using the POST method */
out.close();
String inputLine;
BufferedReader in = new BufferedReader( new InputStreamReader( connection.getInputStream()));
while ((inputLine = in.readLine()) != null) /* Retreive the URL content & initialize empDetails */
empDetails.append(inputLine+"\n");
in.close();
catch(Exception e1)
empDetails.append(e1.getMessage());
/* Listener to handle the Actions for the Query button */
class button_listener implements ActionListener {
Applet1 applet1;
button_listener(Applet1 applet1)
this.applet1=applet1;
public void actionPerformed(ActionEvent e) {
applet1.button1_actionPerformed(e);
Explaination:
a. Create the URL with the following.
URL url = new URL("http://winnt-nsc.in.oracle.com:8888/web_apps/plsql/
get_emp_data");
b. Call the URL object's openConnection method to connect to it. This
initializes a communication link between your Java program and the URL
over the network URLConnection connection = url.openConnection();
c. After the URL is opened, it creates two streams, one input stream to
read from the open connection, and one output stream to write to the open
connection. An input stream needs to be used to retreive the contents
of the URL. An output stream can be used to pass data to the URL
(such as Posting paraemeter values to the URL).getInputStream () and
getOutputStream methods of the URLConnection object could be used to get
the input & output streams respectively.
By default the input stream is enabled & the output stream is disabled.
You need to explicitly enable the output stream if reqiured by using the
setDoOutput method of the URLConnection object connection.setDoOutput
(true);
d. In the example the deptno is the parameter name, and the value is
retreived using deptno.getText().
Example uses the POST method to pass the parameters.
The parameter needs to be passed using the format
parameter_name=parameter_value, which is done by
out.print("deptno="+deptno.getText());
Paraemeters could be passed using the GET method, by just appending the
parameters in the above format to the URL. In this case, you do not need to use
the OutputStream of the URLConnection.
Example : http://winnt-nsc.in.oracle.com:8888/web_apps/plsql/
get_emp_data?deptno=10
Unless the URL length limitation is reached, try to use GET because of its
simplicity.

I have a similar problem where I use a package for the Servlet. The "servlet" consists of a large number of classes that do queries, reply generation and so on. I have no way of configurating the OAS the same way I do with a Apache JServ, or is there a way?

OAS / Jservlet / Java Packages

OAS 4.0.8
Is there a way to have a virtual map to servlets that protects the world from knowing what package a particular servlet is implented in.
For example, lets say I have HelloServlet in the package com.blah.
The only way I have found to reference it so far is to have a url like the following: http://myserver:8180/jservlets/test/com.blah.HelloServlet
The virtual paths get part way there by allowing you to map /jservelts/test to a physical path.
What I need next is something like
Hello maps to com.blah.HelloServlet.
thanks for your help,

JServlet / DBServlet in OAS 4081

I created a Servlet according to the steps given in the OTN website.
It access tables EMP and DEPT from the database.
When I tested it from JDeveloper, it worked perfectly well.
When I tried to access it through Browser / OAS 4081, it didn't work.
It is looking for DBServletImpl.class
Can anybody help me to find out where this class exists and how to include it.

There is a sample code in technet

Can this be done?

OAS 4.0.8.1 - Some issues

1) Is connection pooling possible in OAS 4.0.8.1 ?
2) Can JDBC 2.0 drivers be used with OAS 4.0.8.1 . If yes , can we register the datasource in the JNDI namespace ? How ?
null

Hi, working on a similar project with Oracle 8.0.5. database server and OAS4.0.8.1 JServlet Cartridge. Do not have answers to your questions, but have some more.
1) oracle.html package:
a) How can I add events like onChange, onClick etc. to Items?
b) Font and TableRow class do not provide closing tags. Is it a bug? Any workarounds?
2) Cannot store objects like connection pools, etc. in servletcontext as when I try to get them in another servlets, it gives ClassCastException. However, if I get them in an Object reference and display Classname, it does display the proper class name.
getServlet also does not work so that I can share a global object with all servlets. Is it a but in OAS.
Any other way by which I can share global objects across servlets.
3) If I put a class in a CLASSPATH directory of the OAS application, and if that directory is not a virtually mapped directory, it is unable to locate my classes. Wonder how it is able to locate the oracle.html libraries which I access in the same way.

OAS 4.0.8.1 - An application error has occured

Hi !!!!
I have created an small servlet application: HelloServlet.
I have followed the instructions of tutorial contained in the Developer's Guide
I have compiled the servlet without problems.
But When I write the URL in my browser
http//host.domain:port/virtual_path/HelloServlet
occurs the next:
"An application error has occured. Please try again."
Also I have created a DAD for accesing a database Oracle8i 8.1.5 existing in the same machine but other ORACLE_HOME that OAS.
Then, I installed the utilies: Logger Tables, PL/SQL Toolkit, Log Analyzer and Database Browser, in this order.
But, when I try to access the Database Browser utility appears the same message:
"An application error has occured. Please try again".
Any help well be appreciated???
Many thanks.

2.-a servlet with database access.
But, when I am going to deploy from my browser, then next message appears
An application error has occured. Please try again.
I increase the virtual memory but this I do not work.
I check the wrb.log file and there isn't a error that to me it orients. My severity leves is 15.
Now, my application log file, named jservlets.log, has the next error, but I don't understand it:
`An internal error has occurred: can't find cartridge class name. Please try again.`
`Java cartridge runtime initialization complete.
I Already don't know to do.
