Protect JSP application

How can I protect a JSP application published on server client?
How can I be sure that the client(supose he can and want to understand my JSP code),
does not try to sell the app again?
Thank you.

You can't.
Anyone who can read the files on the server could copy them to some other medium and sell them.
It's the same as with any other software, there's a measure of trust needed between supplier and customer.
You could use some form of hardware dependent key that is referenced from each bean or servlet you use and causes it to fail if invalid, but that would not protect your JSPs which are after all plain text files and can be easily edited (that's the big plus of JSP after all).
If your relationship with your customers is so poor that you can't trust them with source code (which is what JSPs are effectively) you may be better off changing your business model to either get other customers or get your customers to pay you not just for the software but also for hosting it.

Specify initial page following mod_osso login for JSP application?

I'm developing a JSP application that is stand-alone from Portal, but that is protected via mod_osso. (What's the proper term for this - its sort of a Partner application, really an External application, but not registered w/ Portal at all...) Following mod_osso validation, if the login page was brought up (ie, the user was not signed when the application page was requested), I'd like the user to be taken to a 'default' application page (where I can retrieve other user info from the db for use in subsequent pages of the app.) Is there a way to specify this w/ mod_osso? (ie, after login, take user to a specific page.) I could put a flag in the session, check it on each page (ie, Boolean hasVisitedHomePage or such), then redirect to the home page if its false, but would rather not do this if there is a smarter method.
Thanks,
Jim

Following are the steps to use SSO with an J2EE application:
Steps to enable SSO/OID user authentication to your J2EE application
1)     Deploy your apps to Oracle9iAS mid-tier instance e.g. mid-tier-host
2)     Connect to your SSO server in your infrastructure host as follows:
http://inf-host:<port>/pls/orasso/orasso.home and
Login as orcladmin. The default password should be same as your IAS_ADMIN password
3)     Click on SSO Server Administration and then Administer Partner Applications
4)     Click on Add Partner application
5)     Enter the following information for your environment and click on Apply:
Home URL: http://inf-host:<port>/osso_login_success
Success URL: Home Page for URL for your apps which you want to secure
Logout URL: http:// inf-host :<port>/osso_logout_success
6)     Logon to EMWebsite for the Mid-tier Oracle9iAS Instance
Select the HTTP Server -> Advanced Properties -> mod_osso.conf and add the following. Please make appropriate change for your environment
<Location /context-to-secure >
AuthType Basic
require valid-user
</Location>
And then restart HTTP Server
7)     Now when you access your apps, the logon screen will appear
hope this helps

Portal Security with existing JSP Applications

Hello,
we have some existing JSP Applications an want to include them into out portal. They are currently running on iAS as standalone applications. But we also want to protect them using portal security.
How is it possible to use Portal Security for those JSP Applications.
Regards,
Frank

Hello,
currently I don't need to include them as portlets.
I included the first Page as jsp Report... because of that, this jsp is secured. But my application has more jsps.
Probably I could set an sessionvariable in the first protected jsp and check it in all other jsps. If this sessionvar is not existing, the user is not allowed to see this application.
Currently I have no other idea.

Frank

Error deploying BC4J JSP-application to OC4J

Jump to the following link, read, and understand everything:
Re: How to use the classes of ott generated in Visual c++
Also, locate the C:\Jdev9i\BC4J\bin\bc4j2oc4j.bat file, make the necessary changes for the OC4J_HOME, JDEV_HOME, and JDK_HOME and run. This file should setup the BC4J libraries in your OC4J installation. Be sure your OC4J_HOME\j2ee\home\admin.jar is version compatible with the JDEV_HOME\j2ee\home\admin.jar.

Are JSP applications Secure ????

Hi all,
We develop software based on the J2EE, and the products we develop come with a licensing, so even though we plan to give the entire source code to the client, for more number of user licenses the client has to contact us. In such a scenario, and development being based on JSP core, and we giving the code to the client, it is highly insecure that the code can be easily De-compiled and the code which handles the licensing stuff be commented out or removed. Under such circumstances, how are we to build secure JSP applications. Is there any other alternative to this apart from code obfuscation ? Can code obfuscation be done to JSP pages too, and how secure is it going to be since ultimately i can get the code from the servlet inside the work folder of the servlet / jsp container ?
Can anyone throw some light on this ?
Cheers,
-Prashant.

Hi Cetin & Grant,
I do agree with you both, but dont we as developers
anticipate such things and plan for it well ahead. If
that is the case then if it is going to be a crime
free world out there then why do we need all these
security & protection mechanisms. I guess my message
was misunderstood or rather what I wanted to say wasnt
properly given in words ?No, I understood - I just disagree that there's a Java-specific problem here.
Let me restate what I actually wanted to know, let us
take for example an application created using
Microsoft technologies, as I am going to distribute it
in binary form or an executable form, the person who
buys it from me cannot re-engineer it that easily as
compared to a java-based application. This is due to
the fact that De-compilers are very easily available
nowadays which can easily help in re-engineering,
under such circumstances as Java Developers is it not
our duty to find out alternate measures to handle such
occurances.The key disagreement I have with you, I guess, centers on the phrase "distribute it in binary form or an executable form, the person who buys it from me cannot re-engineer it that easily". I will point out that (speaking of Microsoft products) Microsoft Office and Windows itself are quite possibly the most-pirated applications in existence - and neither is written in Java. Both are typically available in pirated versions within days of being released (sometimes even before release!).
Piracy via decompiling has been happening for decades. I have, in fact, watched someone break a license-based protection scheme on a compiled binary in about 30 minutes, using nothing more than a debugger and a hex-editor.
You should probably obfuscate your code, yes. You should probably have a licensing scheme, yes. You should almost certainly not spend very many machine- or thought-cycles on it - the best you can do is deter the "casual thief". And it's not a problem caused by, nor even exacerbated much by, Java. Some very bright people in our industry have spent a lot of time working on preventing piracy - and we've failed.
Am I missing anything here. Does Sun provide any
explanation to this, like kind of using code
obfuscators etc.Obfuscation helps, yes. Try Google and search for "java obfuscator"; there are a number of them out there.
That you're planning on giving your source to your customers makes the problem even more exciting. My take would be, don't spend more than a week on designing and implementing whatever scheme you come up with. That should be sufficient to protect your product from most customers (because most customers are, in fact, honest!) Sprinkle copyright notices liberally throughtout your code, and in the bytecode as well (think compiled-in "public static final String copyright = "blah blah blah 2003";"). Make sure your license agreement mentions draconic penalties for theft. Then, make sure that your product delivers good value for the dollar, and is dead easy to install and run legally. This is about the best you can do.
Your stuff will be used illegally - but the goal is to keep that down to levels that are manageable (i.e., profitable for you and your company).
Good luck!

How to protect an application running on IIS with OAM 11gR2

Hello Gurus,
I have a question regarding protecting an application running on IIS with OAM 11gR2. We have an OHS server running and all the requests from the users are coming to this OHS server webgate for them to login using the SSO login page. These is all solaris. I am protecting other applications like pplsoft moduels with this OHS instance and OAM server. There is another application that I need to protect which is itself running on IIS windows machine. I need guidance as to -
1.) Do I need to install a windows version of webgate to protect this IIS based application?
2.) Or I can still protect and proxy requests from this application to current OHS instance? How can I do this?
3.) Or Do I need to proxy requests directly from IIS to OAM weblogic server?
Please advise to the earliest as this is an urgent issue.
Thanks !!

From your description it is not clear how exactly architecture looks like
We have an OHS server running and all the requests from the users are coming to this OHS server webgate for them to login using the SSO login page.
is this OHS centralized login farm ? (Case 1)
OR is this OHS server (with webgate) acting as virtual web server hosting multiple web sites so that request to any site passes through this OHS/webgate (Case 2)
1.) Do I need to install a windows version of webgate to protect this IIS based application?
If case 1 then you need to install 10g webgate on top of IIS server to protect this application
If case 2 then you can just proxy request from OHS to IIS server. As every request passes through OHS user will be authenticated before request hits IIS
Look at Product documentation for virtual web sites : http://docs.oracle.com/cd/E27559_01/admin.1112/e27239/shared.htm#autoId12
It has steps to protect virtual web sites.
Also you need to make sure no one hits IIIS web sites directly.
Hope this helps

How can I port an existing Tomcat (JSP) application in SAP Netweaver 2004s

Hi All,
I want to port an existing JSP application (using Tomcat as Web server) in SAP Web AS 6.40.
Please any one suggest me.
Eagerly looking forward to your reply......
Thanks and Regards
Avijit Dhar

Hi,
The maximum number of work processes depends on several things like the below.
1) Majorly on Your primary Memory
2) Hardware capacity
3) Operating systems
4) SAP version as well...
You need to calculate the work processes with your primary memory.
Every work process should take 150 mb space on memory.. so you need to increase the work processes that should be campatible with your primary memory.
And please read the OSS notes as suggested by our frnds then go ahead with your rquirement.

How to protect an application running on weblogic through OAM

I have a requirement where in I need to protect an application (URL/root) deployed on weblogic through Oracle Access Manager.
Here's what I did:
Installed webgate on the Host where the application is deployed.
Configured the webgate on Access System Console.
Configured the policy domain -
a) Mentioned the Resource type and URL to be protected
b) Authentication Type (Basic)
c) Autherization Rules (Anyone can acess)
Issue: When I try to access the application http://<hostname>:7001/myapp
I expect the webgate/OAM to intercept this request and challenge the user with the basic authentication
but the request is carried through and the Home page of myapp is displayed.
Do I need to do some configurations in the webserver (httpd.conf) or deployment descriptors in the application server to get the authentication?
The application above can also be substituted with Oracle Identity Manager, where I'm getting the same result. I'm able to view OIM Home page without prior authentication. I tried protecting with the following pattern <host variation>/xlWebApp
I am new to Oracle Access Manager and looking for some guidance.
Thanks

Hi Joe,
1. Please elaborate step2 or guide me to a link where I can configure reverse proxy from Apache Webserver to weblogic. I think here's where I'm going wrong.
For more details on proxy refer to these links:
http://download-llnw.oracle.com/docs/cd/E13222_01/wls/docs90/plugins/apache.html#119517
OHS to Weblogic Reverse Proxy configuration Problem
After this configuration, won't I be able to access the application /myapp running on weblogic through port 7001 and will I have access to it only on port 80 (web s erver default port)?
You will be able to access the application through 7001, but the request will not be intercepted by OAM. The request will be processed directly by your myApp.
2. I did some reading and found some instructions on using weblogic SSPI plugin. Is this required at all? When is this used?
You can use SSPI Connector if you want to protect the weblogic port. i.e., OAM intercepts the request when you access the application on 7001 port.
Hope this helps

====================
thanks

I had very similar problems with adding the correct JDeveloper .jar files to Tomcat's lib folder, but did eventually resolve my issues.
The problem I am having now, however, is the following error message:
Error Message: oracle.jbo.html.RequestParameters.addParameter(Ljava/lang/String;Ljava/lang/String;)V
Yes, I have deployed the bc4jhtml.jar file from JDeveloper to Tomcat\common\lib!
My web-app is a very simple BC4J JSP application. I have one BC4J component in its own project and JAR file, and one JSP referencing that BC4J component - I deploy the BC4J JAR along with the WAR file from the JSP project. Needless to say, the JSP works fine within JDeveloper..!
I'm using JDev 9.0.3 and Tomcat 4.1.12. Does anyone have any suggestions?
Thanks,
S.
