Get installation path of web application from class file

Can anybody tell me how I can get the path on disk to the root of my web application from a class file. Im running under Tomcat 5.5 and I have 3 copies of the same webapp under 3 differenet directories:
C:\xxx\dev\yyy
C:\xxx\test\yyy
C:\xxx\prod\yyy
Based on which directory the web-app, I need to do a lookup on a properties file to pull the right jdbc connection to connect to the appropriate database. So it would be similar to using getServletContext().getRealPath("/") from a .jsp file.
Thanks,
Jason

Sorry for not clarifying. I have a properties file with name/value pairs. I know where this properties file is and I can do a lookup in it. In this file, I have jdbc connection names which point to corresponding jdbc resources in my context.xml file.
jdbcDevDatabase=jdbc/tfmDev
jdbcTestDatabase=jdbc/tfmTest
jdbcProdDatabase=jdbc/tfmProd
These connections are for dev, test and prod databases. Now based on where the web-app is installed on disk, i.e-dev dir, test dir, prod dir, I want to retrieve the corresponding connection. The problem is I don't know how to get a handle to the web apps real path on disk without access to the request object or using getServletContext().getRealPath("/") which are not available to me in a class file.
Thanks,
Jason

Seems that it happened due to updating weblogic version (changes in jee, jms, ejb, jpa versions?). Could you please advice me how to fix this issue?
Thanks, Ilya

I belive there is no problems for this change, because the versions are the same for java at least for OaS, for weblogic you should see documentation. I think you can try deploying you app to new environment if you get any noclassdeffound error or something like it then you could have problems for versions.

Accessing web application from users' PC

Hi there,
My server is up and running, appsets are working nicely and everything works perfectly. But I have an issue when accessing the web application from a user PC on the same domain, and I'm not sure if it's down to me or not.
From the users' PC, with BPC for Excel open, I click on the link for BPC Web, and Internet Explorer opens and attempts to take me to the web app. But if the address contains the server name, it doesn't work. If I manually type the IP address in instead it works.
Why is this? Have I forgotten to do something, or is it a DNS problem, or other local IT issue?
I'm sure I've missed something really silly, but can't figure out what!
Any ideas appreciated!
Thanks a lot,
Jason

Hi Akim,
I think this is actually part of a wider problem - I have been testing this on my local PC (over the clients' VPN) and now it works fine. But I just logged onto the clients PC using Webex and I can't get into ANYTHING! Not the Admin client, not BPC for Office, not the web application - nothing.
I think I need to go there on monday and actually go through this with one of their network guys - I'm not convinced that it's a problem with the server anymore!
Thanks for your help - I will keep you posted!
Jason

Can you reload web application from the Weblogic console?

          Good day, eh!
          Can you reload all your jsp/servlet classes of your
          web application from the Weblogic console?
          A one big button labeled 'Reload application' would be very
          good property in Weblogic

Hi,
          I agree it is a much needed feature. Suppose I just change an init
          param of one application in the web.xml, I don't want to take down the
          15 other webapps running on my server just to be able to have that web
          app restart and re-read is configuration. Of course, I could program
          some servlet that allows changing application attributes and to enable
          restarting, but really this a)does not cover all the cases (i.e. addind
          an EBJ reference binding to web.xml) b) should be provided by the app
          server, not programmed by every little programmer again & again.

Is it possible to invoke external REST web service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4)

Is it possible to invoke an external REST web-service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4) with parameters as input and manipulating the response depending on the type of parameters it gets back. Then invoking an Adobe Form and prepopulating the Form based on the response parameters? Do you have sample projects that do this invocation. The part highlighted in red is what I need examples.

You can simply use "Execute Script" operation in Workbench and make use of java.net.URL. Below links should help :

SSO to Web Application from Portal

Hi,
    I am working on a scenario where I need to access a Web Application from the Portal.
    I read about the Application Integrator that is provided by the Portal .
    I wanted to know that can I only have SSO to those Web Application that accept the userid and password and as URL parameters using Application Integrator , ie: those applications that have post method cannot be integrated.
   Please help me out with clearing this doubt.
Thnx,
Pravesh Puria.

Hi Abdulbasit ,
    Please give me more details , we have a Lotes Notes Web application hosted on Domino server , another is J2EE based application. I need to achieve SSO to each of these applications from the SAP Portal.
   I followed the below listed steps:
   Created two systems one for each Web application based on the template generated from the application integrator. I entered the user mapping values for both the systems.
   I also created two IViews. When I preview , the logon page of the web application opens but the user credentials are not passed to the application.
   Please help me with the steps to achieve the SSO , from the reply I interpret that Logon ticket method was used to achieve the SSO and user mapping.
    My email id is : [email protected]
    It will be of immense help to me.
Thnx,

Call Web Applications from Xcelsius using LiveOffice connections

Hi,
I have read the HTG: "How To... Call BEx Web Applications from SAP BusinessObjects Dashboards (Xcelsius) and vice versa" here on SDN. Problem is that it is using BW Connection as connection.
Is it be possible to call web applications using Live Office connections?
Br,
Sonni

Hi Sonni,
If you are building dashboard using live office connection and you want to give a drill down to detailed webi or crystal report, you can use Open document interface. In the particular HTG you have mentioned, Open document approach is not possible because dashboard is based on SAP BW. Since you are using live office, i guess you have the source report published in BOE and you can use open document approach here.
If this is not your requirement please mention your exact requirement.
Hope it helps you.

How to create JSF application from xsd files?

Hi,
We have many xsd files describing xml's which we are supposed to send to web services. Application which we are creating should allow user to fill xml documents with data and then we should send those xml files to some web service. We want to automatize as much as possible the process of application creation to avoid possible errors and to minimize our efforts (there are plenty of quite complex xsd files).
Our first approach was: we used Oracle JSXB to generate java classes basing on xsd files (using JDeveloper 10.1.3.2.0.4066). Then we tried to generate DataControls, but this action fails with following error:
Window title: Error in init bean
Message: Could not complete initbean because it would result in an invalid document
Details: oracle.bali.xml.model.XmlInvalidOnCommitException: SEVERE: Wartość atrybutu Name nie jest typu ID (Value of Name attribute is not of ID type)
Wartość musi być następującego typu: (Value must be of following type)
Nazwa typu: ID (Type name)
Typ pierwotny: string (Primitive type)
Z następującymi więzami: (With following constraints)
zgodne z wzorcem: [\i-[:]][\c-[:]]* (Compliant with template)
[ node = Name ]
<JavaBean version="10.1.3.40.66" id="XSLStylesheet" BeanClass="oracle.xml.xslt.XSLStylesheet" Package="oracle.xml.xslt" isJavaBased="true">
<Attribute Name="classMethodParams" IsUpdateable="0" Type="java.util.Hashtable" />
We tried Sun implementation fo JAXB - it generated different java classes (with annotation mechanism). Creation of DataControls using those classes was successful. Then we created simple JSF page and tried to put those DataControls on it in order to let the user fill it with data. The thing is that those controls are read only as there is no row created in those DC. We can't create any row in those DC as there are only 'commit' and 'rollback' operations. When we try to call 'CreateInsert' operation on child elements of those DC we get error in JDeveloper log window:
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: JBO-29000: DataControl:createRowData
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: DataControl:createRowData
new row is not created and controls are still read-only.
The question is:
1. is there another, more efficient way to create JSF application from xsd files?
2. if this is the best way to do it, what do we do wrong?
Leszek

To anyone who might find it useful: our solution to mentioned problem.
Few tips how to solve described problem:
1. Do not use JAXB (we checked Oracle and Sun)
2. Use castor http://www.castor.org/
a) for each xsd generate java files in separated package
b) use java 1.5 to let castor generate lists
c) use mapping of xml namespaces to java packages to have only 1 implementation of each xsd
3. Create facades - java files for you root-level java objects
4. Right click those facades and choose 'Create DataControl' in jdev
5. Now you may drag and drop you DataControls and use them in your JSF (or UIX) application
I hope it will help someone :)

Call function in main timeline from class file

Hi all, How can a function in main timeline be called from class file?

Hi all, How can a function in main timeline be called from class file?
You can, but you really shouldn't.
Classes shouldn't "talk" to the outside directly.
Use Event dispatching to get things done.
"root" (i just threw up by just typing that word) should be avoided at all cost, especially in AS3.

Deploying application with class files compiled using ojspc

Hi,
I want to deploy the application having class files compiled using ojspc in Oracle9iAS Release 2 rather than having JSP pages.
Thanks,
Pritam

Hi Manoj,
I have tried doing something like this.
If you want to try this out running on a NW2004s.You need to first download the entire project from perforce branch (
tc\webdynpro\clientserver)for NWDS 7.0 and then build the project locally in your java perspective.
During the local build of the project.It will also point out the dependent projects required by this project(clientserevr).
Once the project is build.
Create seperate external jars of the clientserver project and its dependent projects and save them locally.
Open your SDM manager,pick up this jar file from there and deploy it.
Once the deployment is over, the server is ready to run the application you created.
But this make your NWDS2004s to behave jus like NWDS7.0 .
Just a small suggestion ,instead of going through this tedious process you can shift to NWDS7.0 itself.

Java version from class file

How to decide from class file that which java version (1.3, 1.4 etc) was used to compile it?

Sorry I made a mistake,
its minor, major
Dont we have some utility given by Sun for this?
javap -verbose <classname>will print out versions plus more...
Do I need to use InputStream for reading class file then see the version?
DataInputStream din = new DataInputStream(new FileInputStream(classFile));
din.readInt();
short minor = din.readShort();
short major = din.readShort();Why do you need to do this?

Probelm in getting absolute path of the application folder?

I have problem in getting the absolute path of the application folder.
I wriiten the following line in my action class:
String absPath = getServlet().getServletContext().getRealPath("/");
when i run my application 'DTH' in Tomcat server, I am getting correct path :
C:\Tomcat\jakarta-tomcat-5.0.25\webapps\DTH
But when i run this application in weblogic server, I am getting null value for the above line.
Can any one help me in this?

public java.lang.String getRealPath(java.lang.String path)
This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive).
so, getRealPath() might not be a very good approach because of its different behavior when used from a war or exploded application.
What you could do is:
1. pass the path as a parameter inside web.xml (config files, log files etc)
2. For dynamic lookup of files you could make use of ClassLoader.getResource().
Hope it helps.
