Servlet under Weblogic talking to external daemon via RMI

Hi,
We are trying to deploy our servlet-based application to Weblogic 8.1 and have
hit problems with RMI. This application has worked for years under Tomcat.
The servlet attempts to make some RMI calls to an external process which is running
it's own RMI registry. The RMI connection to that external process is being refused
though.
From the Weblogic doc, I've seen information about building RMI stubs using the
Weblogic rmic. But are application needs to support non-Weblogic servlet engines
too so we do not want to have to change our RMI classes around if at all possible.
Does anyone know if it is possible to use standard Java RMI classes inside of
Weblogic to talk to standard RMI classes outside of Weblogic?
Thank you,
Tom

Hi, Tom
Yes, it is possible. I have an application that uses standard Java RMI classes
inside Weblogic. There is a Java Control doing lookup to a remote component.
I had to take care with the permissions in the policy file. If the connection
is being refused, probably you have to review permissions, specially socket permissions.
Bye,
Diana

Insert CLOB into oracle under weblogic

Situation: running my servlet under weblogic, want to insert more than 4000 characters into CLOB of oracle 8.1.7
Problem: cannot be done by using code which is able to do it under tomcat
i use this code in tomcat:
import java.sql.*;
import oracle.sql.CLOB;
import oracle.jdbc.driver.OracleResultSet;
con.setAutoCommit(false);
Statement stmt = con.createStatement();
rs = stmt.executeQuery("SELECT clob_field FROM table where rid=id FOR UPDATE");
rs.next();
CLOB clob = ((OracleResultSet)rs).getCLOB(1);
Writer writer = clob.getCharacterOutputStream();
writer.write(dataString);
writer.close()l
con.commit();
con.setAutoCommit(true);
stmt.close();
after that i know that i can't use API of oracle when i'm using weblogic (e.g. oracle.sql.CLOB)
and i find this code from other user:
import weblogic.jdbc.vendor.oracle.OracleThinClob;
import java.io.*;
import java.sql.*;
PreparedStatement stmt = con.prepareStatement ( "INSERT INTO database VALUES ( ?, EMPTY_CLOB() )" );
stmt.setInt ( 1, 1 );
// inserts a new entry with an empty clob object
stmt.executeUpdate ();
if ( stmt != null )
stmt.close();
// retrieves CLOB-Object
stmt = con.prepareStatement ( "SELECT clob_field FROM database WHERE id=?" );
stmt.setInt ( 1, 1 );
ResultSet rs = stmt.executeQuery ( );
if ( rs.next() )
Clob cl = rs.getClob(1);
Writer clobWriter = ((OracleThinClob)cl).getCharacterOutputStream();
// Open the sample file as a stream for insertion into the Clob column
File testFile = new File ( "file.txt" );
FileReader testReader = new FileReader ( testFile );
// buffer to hold data to being written to the clob.
char[] cBuffer = new char[((OracleThinClob)cl).getBufferSize()];
// Read data from file, write it to clob
int iRead = 0;
while( (iRead= testReader.read(cBuffer)) != -1 )
clobWriter.write( cBuffer, 0, iRead);
testReader.close();
clobWriter.close();
if ( rs != null )
rs.close();
if ( stmt != null )
stmt.close();
// update clob-data in database
stmt = con.prepareStatement ( "UPDATE database SET clob_field = ? WHERE id = ?" );
stmt.setClob ( 1, cl );
stmt.setInt ( 2, 1 );
stmt.executeUpdate();
it throws java.lang.ClassCastException: oracle.sql.CLOB
but i haven't imported or used any API from oracle.........
please help
thanks

hi,
unfortunatly, you can't do this with welbogic6.1 because it 'manage' itself oracle librairies (weblogic.jar),
here is the way i solved the pb for BLOB :
i replaced :
BLOB blob = ((OracleResultSet)rs).getBLOB(1);
by
weblogic.jdbc.rmi.SerialOracleBlob cast1 =(weblogic.jdbc.rmi.SerialOracleBlob)rs.getBlob("myBlob");
weblogic.jdbc.rmi.internal.OracleTBlobImpl cast2 =(weblogic.jdbc.rmi.internal.OracleTBlobImpl)cast1.getTheRealBlob();
BLOB myBlob = (oracle.sql.BLOB)cast2.getTheRealBlob();
it is the same for clob (i suppose ^_^)
hope this helps !
Badr.

404 error while invoking servlet in weblogic 6.0

 Hi,
 When I try to invoke a servlet from weblogic 6.0, I am getting
 404 error. I have copied the HelloWorldServlet class into defaultWebAppl_Server/WEB_INF/CLASSES
 directory and when I invoke the HelloWorldservlet, its giving file
 not found(404) error. I am doing exactly what has been given in
 the "quick start to servlets" in weblogic 6.0. I am using Windows
 NT.
 I have also another problem when I use java utils.dbping to test
 the connection to my oracle8.1.8, its giving licence file not found.
 Could some one help me out from this.
 Thanks in advance,
 Ramu


 Hi kumar,
 I have been keep trying to solve that. After some time Suddenly
 "Error 404" disappeared and instead "Error 500" came. Okay kumar,
 here is what I am doing...
 I have installed weblogic6.0(eval), oracle 8.1.6 on Windows NT4.0.
 I have installed oracle Enterprise edition from CD "ORACLE 8.1.6
 for NT".
 I installed the weblogic under D: drive.
 I did class path settings as given in documentation. But Iam not
 sure whether I need to do any other class path settings.
 I was able to run pet store application given in weblogic server.
 I went to "quick start" section and ran HelloWorld.jsp page from
 "DefaultWebApp_myServer" directory.
 I was not able to run servlet program as per given in the "quick
 start". I am getting
 "Error 500---Internal server error"
 The server encountered an unexpected condition which prevented
 it from fulfilling the request"
 I have modified the web.xml under WEB-INF of DefaultWebApp_myServer
 as per given in the quick start.
 Here is the quick start link For you reference(as what I talking
 about)
 http://edocs.beasys.com/wls/docs60/quickstart/quick_start.html
 In the web.xml, I have given <servlet-class> as just HelloWorldServlet,
 since I directly copied the file from some other examples directory.
 But still I am getting 500 error.
 Here is the url that I am invoking...Http://ramup:7001/quickStartServlet
 Coming to your oracle connection test, I did exactly what you said.
 kumar, I have executed the command
 "D:\bea\wlserver6.0\config\mydomain>java -classpath %classpath%;D:\bea
 utils.dbping ORACLE
 >scott tiger TestDB"
 Where TestDB is the database that I have created while installing,
 but I am not aware of the instance you said.
 Here is what I got after executing the command.
 --------*******-------Pasting the ms-dos command results----**-
 // This mode is superior, especially in serverside classes because
 // it avoids DriverManager calls are class synchronized, and will
 // bottleneck any other JDBC in the server, even already-running
 // connections, because all JDBC drivers use DriverManager.println()
 // to log info and exceptions, and that call is also class synchronized.
 // For repeated connecting, a single driver instance can be re-used.
 **** or ****
 Class.forName("weblogic.jdbc.oci.Driver").newInstance();
 java.sql.Connection conn =
 DriverManager.getConnection("jdbc:weblogic:oracle:TestDB", "scott",
 "tiger")
 **** or ****
 java.util.Properties props = new java.util.Properties();
 props.put("user", "scott");
 props.put("password", "tiger");
 props.put("server", "TestDB");
 Class.forName("weblogic.jdbc.oci.Driver").newInstance();
 java.sql.Connection conn =
 DriverManager.getConnection("jdbc:weblogic:oracle", props);
 D:\bea\wlserver6.0\config\mydomain>
 --------*******-------Pasting the ms-dos command results----**-
 I think I have connection to database, thanks for your suggestion.
 Kumar, I have not seen weblogic.properties file any where in D:\bea
 directory.
 Kumar, if you have some time can you jot down the classpath settings
 and path settings for executing SERVLETS/EJB programs.
 Thanks for helping me out..,

Oracle Portal returns 500 error running under Weblogic 11g server

I've got Oracle Portal set up under Weblogic 11g.
SSO running, talking to OID 11g, also running under the same Weblogic 11g server. Tested SSO, it is working well.
After the install (no errors or issue on install), I go to http://<server>:8090/portal/pls/portal and geta Error 500 - Internal Server Error.
I traced down the problem to OHS - in ohs1.log:

Yes, it seems you are correct....this is from WLS_PORTAL-diagnostic.log

HTTP connection from OSB web service to external system via a Proxy Server

Dear experts,
May I know has anyone tried to use HTTP protocol to send a request from OSB web service to external system via a proxy server? Heard that we need to establish some sort of tunnel (socket) to talk to Proxy Server. Can you please any have sample code or configuration steps to share?
Thank you very much!!

Qosmio G30 - external screen via HDMI connection - bad resolution

Hi! This problem is driving me crazy, please help if you can...
I have just bought a G30-102 and I'm trying to use it with an external screen via the HDMI connection. The problem I'm having is that the native resolution of 1920x1200 cuts off the edges of the desktop and the quality looks terrible - its almost like the whole screen is zoomed in. I tried this with a BenQ FP241wz at first (which is 1080i 1920x1200) and the Toshiba helpline couldn't find a solution either - even after painfully reinstalling all of the drivers etc.
Its been going on for so long, I thought that I would try it out with my HDTV instead, just to be sure it wasn't a monitor issue. So I tried it with my Toshiba 32WLT66 - and have just found that it has exactly the same problem.
All of the display settings appear to be correct and the G30 is convinced that the output is correct, so the question I have now is - do you think that its a problem with my HDMI port?
Please help, I'm a designer and it is essential that I use the machine on a large screen. If this is a problem with the G30 hardware I need to talk to Toshiba immediately about replacing or fixing it.

Hi - thanks for the reply!
My BIOS doesn't allow me to choose much for the display - just between PAL and NTSC really.`As for the document, thanks for the link - unfortunately though there wasn't anything in it that I haven't already tried.
What would be the most obvious thing that could be wrong? Faulty port? Faulty card? Or could it even be as simple as a faulty HDMI lead?

Datamart management from cube to external system via XI

Dear All,
I upload data to another external system via XI from an infocube.
Data upload is done with delta update to the cube, also, deltas going to the external system.,,
I have two cubes. One of them is filled with deltas by transformation (i.e 7.0 property). But other is filled with update rules (i.e 3.5 property)..
when i click on data mart status on the cube that filles with 3.5 property nothing happens. No pop-up screen opens for me to delete the datamart status of the cube.
However, when i click on the cube that filles with 7.0 property, a pop-up screen opens for me to reset last delta.
Can you please advise?

SP

You can configure multiple Proxy Servers for each Proxy Server resource. This enables Oracle Service Bus to perform load balancing and offer fault tolerance features for the Proxy Server resource.
7. If the Proxy Server performs proxy authentication, enter a user name in the User Name field, and the associated password in the Password and Confirm Password fields.
These fields are optional, and required only if the Proxy Server is secured.
8. Click Save to create and save the Proxy Server resource in the current session.
9. To end the session and deploy the configuration to the run time, click Activate under Change Center.

Essbase External Security via Shared Services

I have hit a problem with essbase external security via shared services, might be fairly trivial, first time doing this.
In the install guide for essbase 9.3.1 it mentions not to use the user 'admin' when firing up essbase server console mode for the first time if you intend to externalise security to shared services in the future.
I have followed this recommendation and used a different username 'essadmin' for the first time essbase server is started up. While still in native security mode, I sign in via EAS 9.3.1 and create myself another admin account just in case.
I cold backup shared services SQL repository and OpenLDAP repositry before externalising essbase security. Also I backup the essbase sec and cfg files just in case.
Then I start it all up, go into EAS and select to externalise security, this takes a few seconds, and all seems well.
Now in shared services I can see the essadmin user ID and everything appears to be OK. However when I look under the projects node, I see "Analytic Servers:myhost:1", then below that another green icon "Analytic Servers:myhost:1", but when I click on the second green icon I get "Login fails due to invalid login credentials".
What have I done wrong ?

Hi,
I don't think you've done anything wrong. You just need to provision your shared services user with access to Essbase. Right-click on your user, select provision and then give them the required Essbase rights.
Hope that helps,
Gee

Double submission problem in J2EE application under Weblogic 8.1 SP2 server

Hi,
We are facing double submission problem in our J2EE application which is running under Weblogic 8.1 SP2 and for the same we already implemented or added the below preventive solutions.
1. We disable the SUBMIT button once the user clicks it.
2. We preventated pressing 'F5' button and clicking 'Refresh' button in the browser.
3. Also we tried to prevent by declaring the idempotent is 'true' under weblogic-ejb-jar.xml as below.
<stateless-bean-methods-are-idempotent>true</stateless-bean-methods-are-idempotent>
So please somebody help us on this issue like how to prevent in some other way.
Regards,
Dinesh.

I have no idea why you would think changing your EJB configuration would have anything to do with preventing double submission at your servlet layer.
One technique I've seen for preventing double submission was first used in the Struts framework several years ago. When a page is "prepared" for display, a token value is created and stored in the session. The page is displayed with a hidden field containing that value. When the page is submitted, the value of the hidden field is compared with the value stored in the session. If they're not equal, the submission is ignored.

Deepak,
 Are all the classes used by CustLogin in System Classpath or under
 web-inf\classes directory?

JDev11g : How to add java servlet under ADF security policies

I'm trying to set a same login on http servlet ( i create it trough wizard in jDev ) as it is for other .jspx pages.
I configured the jazn-data.xml and login ( user roles, realms ) is working fine.
But i can't configure http servlet to be under this authorization.
This problem occured when I was migrating from jDev 11g TP4 to production also from OC4J to WebLogic,
but if I create a new http servlet I am also unable to put it under JAZN authorization.
Thank you in advance for your help, Rok Kogovšek

I reproduced problem on new test application, it was working fine until I set up ADF Security by wizard.
I choose ADF Authentication and Authorization then Http Basic Authentication ( on real project is form based but probablly this doesn't matters )
then for Identy store I chose Application XML, no automatic grants and without redirect.
I also set inside web.xml this ( to put servlet under same login as other pages ).
*<security-constraint>*
*<web-resource-collection>*
*<web-resource-name>testServlet</web-resource-name>*
*<url-pattern>/test</url-pattern>*
*</web-resource-collection>*
*<auth-constraint>*
*<role-name>valid-users</role-name>*
*</auth-constraint>*
*</security-constraint>*
When I finish this i got same error as on first project.
Here is whole error:

Using servlet in weblogic server

hi, guys,
I have done quite a few research about using servlet in weblogic server, but still can't get it work, hope you guys can provide some suggestion. Thank you in advance.
I have a folder structure like this:
There is a "Jsp" folder under the "WebContent", and there is a configJsp.jsp file inside this folder, which is: 
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
<title>Insert title here </title> 
</head> 
<body> 
<form method="POST" action="Config"> 
<input type="text" name="myText"/> 
<input type="submit" name="mySubmit" value="submit"> 
</form> 
</body> 
</html> 
And then under the "Java Resources", there is a "servlet" package, there is a ConfigServlet.java file inside, which is like this:
 
package servlet; 
 
import java.io.*; 
import javax.servlet.*; 
import javax.servlet.http.*; 
public class ConfigServlet extends HttpServlet 
{ 
public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException 
{ 
doPost(request, response); 
} 
 
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException 
{ 
String textContent=request.getParameter("myText"); 
response.setContentType("text/html"); 
PrintWriter out = response.getWriter(); 
out.println(" <html>"); 
out.println(" <head> <title>ServletCommit </title> </head>"); 
out.println(" <body>"); 
out.println(textContent); 
out.println(" </body> </html>"); 
} 
} 
and I add the following mapping configuration into web.xml:
<servlet> 
<servlet-name>Config </servlet-name> 
<servlet-class>servlet.ConfigServlet </servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>Config </servlet-name> 
<url-pattern>/Jsp/* </url-pattern> 
</servlet-mapping> 
I run the application, click "submit", and got the following error message: 
Error 404--Not Found 
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found 
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. 
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. 
I guess there might be something wrong with the jsp and servlet mapping, but don't know what exactly it is, and have tried to change some configuration as well, but they don't work. This has annoyed me for a few days, hope there is someone who can be so kind to help me out of this. Thank you again.
null

to james.bayer: 
I tried modifying my web.xml like the following: 
<servlet> 
<servlet-name>Config</servlet-name> 
<servlet-class>servlet.ConfigServlet</servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>Config</servlet-name> 
<url-pattern>/Config</url-pattern> 
</servlet-mapping> 
is that what you mean? but the same error appear again, it doesn't seem to be able to find the servlet. 
I am using an BEA workshop for weblogic platform 10.0. Actually, I am trying to develop a portal, and I need a jsp to be included in it, and will need to deal with the form submit. The jsp is under a portal application, does it matter? Or is it different with a normal dynamic web application? Thank you for your advice.

UWL object link missing parameters when jump to external page via portal

We configured SWFVISU in ECC to jump out to an external application via a portal page. Our resultant URL looks like this:
http://XYZ:50000/irj/servlet/prt/portal/prteventname/Navigate/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultDesktop!2fframeworkPages!2fcom.xyz.portal.frameworkpage!2fcom.sap.portal.innerpage!2fcom.sap.portal.contentarea?NavigationTarget=ROLES%3A%2F%2Fportal_content%2Fcom.xyz.pct.xyz%2Fcom.xyz.pct.rols.func_Sales_Representative1%2Fcom.xyz.pct.wrks.s.func_Sales%2Fcom.xyz.pct.pgs.func_Order_Accounts_OA&uname=USER.CORP_LDAP.mdeklerk&langu=EN
BUT the work item object link parameter i.e. Sales Order No. does not get passed/attached to the string. What are we missing?

It is passed as an implicit UWL parameter and will not be displayed in URL. You can read this parameter from webdynpro application.

Need help with getResource() problem under weblogic 6.1

Hey all,
 I've got a serious problem that I can't figure out. This should be really
 simple - but it's alluding me. I have an ear file with a number of servlets
 inside it. This ear file also contains a resource that my servlets want to
 read from. This resource is located (within the ear file) at:
 "/content/structure/a.txt". The file contains raw ascii.
 To have my serlvet read from this file, I thought it would be as simple as:
 URL content =
 servlet.getServletContext().getResource("/content/structure/a.txt");
 // pw is an instance of PrintWriter
 pw.print(content.getContent());
 However, when I execute the above I get the following exception:
 java.lang.NullPointerException
 at
 java.net.URLConnection.stripOffParameters(URLConnection.java:1011)
 at java.net.URLConnection.getContentHandler(URLConnection.java:979)
 at java.net.URLConnection.getContent(URLConnection.java:581)
 OK, so fine - I figure that I'm new to this. The documentation for the URL
 class tells me there is another way around this. It says that rather then
 calling getContent() directly, I can open a stream on the URL and read from
 that, like so:
 URL content =
 servlet.getServletContext().getResource("/content/structure/scenario2resourc
 es.txt");
 FileInputStream fis = content.openStream();
 but when I do this I get the following different exception:
 java.lang.ClassCastException: weblogic.utils.zip.SafeZipFileInputStream^M
 at Utility.writeFileToOutput(Utility.java:134)^M
 Apparently this thing is trying to return a web-logic-specific stream (which
 is incompatible with an FileInputStream) - which I don't want to use or
 learn about since I want my stuff to work under other webservers.
 Can anyone tell me what I'm doing wrong? This should be simple.

Wenjin,
 I appreciate your response. I tried treating it as a normal InputStream -
 but it didn't make any difference. Here's what I did:
 URL content =
 servlet.getServletContext().getResource("/content/structure/scenario2resourc
 es.txt");
 InputStream is = (InputStream)content.getContent();
 And here's the exception:
 java.lang.NullPointerException^M
 at
 java.net.URLConnection.stripOffParameters(URLConnection.java:1011)^M
 at
 java.net.URLConnection.getContentHandler(URLConnection.java:979)^M
 at java.net.URLConnection.getContent(URLConnection.java:554)^M
 at java.net.URL.getContent(URL.java:807)^M
 at Utility.writeFileToOutput(Utility.java:134)^M
 You can see that it is definitely breaking somewhere in getContent().
 If you have any other ideas, I'd appreciate hearing about them.
