I just installed java on my computer because i was getting messages that it was no longer there. And I figured out how to solve my problems on my browsers. but i don't see how to enable java in my applications on the hard drive. in particular, i want to use the database in open office but don't see how to enable it.
View RepliesHow to upload file to google drive using java. my java code is.
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE))
.setAccessType("online")
.setApprovalPrompt("auto").build();

So in that file object(java.io.File fileContent = new java.io.File("document.txt");) asking complete file path. But in file upload we can get only file name not path.
I'm new to java and haven't develop any application before that... I need to develop an application through which i can send data from 1 computer to another computer. These communication in between the computers are those are under one router connection. Means they can connect even without internet access
Main concept is as follow
1. Java application on computer A [server side application]
2. Java application on Computer B [Client side application]
3. Java application on computer C [Client side application]
Now computer B and C communicate with computer A. but they don't know about presence of each other
I have an application written in Java on the Linux platform. My application will work the following way:
User A will open application. User B will open application.User A will need to send User B a message but without a socket connection.User B will need to send User A a message but without a socket connection.The user should be able to identify the messages sent to each other.If User A reads user B's message the message will no longer be available in the channel of communication.If one user exits their application their message should be removed.User C should not be able to read user A and user B message (This is only via the application design, no real security here).Applications should be able to work on different machines however they will utilize a shared network mount to access files modified by each other.
I do have to note that the messages being sent is rather small and only 1 message is sent from each user, so in that regard I did not want to setup a client/server model to do this using sockets.
Basically I am looking for a similar concept as a message queue but more relevant to my requirements done in Java. What are some good options to use that will address some of my requirements? I have not touched Java in a long time and only have used it for certain usage so I am trying to get an idea of which current technologies are best for what I need.
I am maintaining an existing Java product (which has a HUGE code-base). I discovered that it is setting (and getting) two of its internal passwords as Java system properties, at no less than 4-5 different places (methods). Now, the problem is, the passwords are being stored as plain text in the Java system properties, and so, the same is visible to external entities, as the application is not using any Java Security Manager. For example, if the application (process) is running on port number 1234, we can run the Java command:
jinfo -sysprops 1234
to view both the passwords as values of the corresponding Java system properties. I wish to ask if there is any remedy to this without changing the existing code-base too much? The desired effect would be to "hide" the two Java system properties (denoting the two passwords) from all external entities.
It may be noted that introducing a Java Security Manager into the application may not be a solution, as if we revoke read permissions from the said two Java system properties using the Java Security Manager, the application codes which read those properties would crash. Same is applicable for storing the passwords in encrypted form, as that would crash all codes within the application which are expecting to read the passwords in clear text form.
To give a bit more context, the said two passwords we are storing as Java system properties are actually passwords to access two key-stores, and Tomcat requires that we store the said two passwords in plain-text format. Any workarounds, such that only Tomcat will be able to see the two passwords as-is, while they will be invisible to all other external entities?
Or, is there any way to place the said passwords in other in-memory locations (like static variables) which only Tomcat can (be made to) read instead of placing them as system properties which is exposed to anyone?
I have a problem with several java applications. When I start them Java wants to connect to the certificate authority, to check if the certificate is still valid and not on a blacklist.
The problem is: my whole internet is behind a password protected proxy. If I open my browser i get a windows with username and password. I enter it and internet in the browser works. But for Java it isn't working, because I see no point, where I can enter the password and username for the proxy. I can enter the proxy ip and port in the java settings, but not the password and username. So I get a error screen from java, telling me, that java could not connect. I can disable the check in the java settings, but I don't wont that.
Is there a way to tell java, that java uses my proxy with my password and username? I already googled this problem and found nothing except tutorials for connecting with proxy in the java code. But these applications are not from me, I can't change the code ...

1) ComboBox
2) Instance
3) Save and Cancel
I wanted some validation here :
For example:
- The Instance Text box and SAVE button should be disabled. When the pop up appears.
- The Instance Text BOX gets enabled only when any selection happenes in COMBO Box
- The SAVE button gets enabled only when COMBO BOX and INSTANCE TEXT BOX is filled.
- Let the CANCEL button be enabled always.
I have been playing around with a snippet I wrote to get the Label on a drive (below). It works fine for me (though I will take any constructive criticism).

I have two separate applications who will access the same table in a database and the two application will update the table.
How can I make sure the integrity of accessing this table? Is it in the code or in the database level?
We have this website that is run on two web applications. The first web application hosts the home page and clicking certain links in the home page would forward it to pages of the second web application where certain functionalities can be done. Now, there has been an initiative to redesign the site to have a login page and only logged in users could browse it. This would mean a login page being created in the first app, and when links to the second application are clicked, the pages are supposed to forward to it with the same session of the user that logged in.
We have already creating handling to pass the session from the first app to the second. Logging out from the first application would also invalidate the same user session in the second application. My questions is, is this a bad idea? would it be better to combine the two apps even if it would mean a huge impact?
or is there are better way to do this? like set it in web.xml. I have read that you cannot use two context for it.
I'm deployed application A and application B in TOMCAT server applications, the U1 user enters into the application A, he authenticates and generates a call to a page of the app B. As I was able to access the session of user U1 en A from B, it could have a single session.
View Replies View RelatedI would like users in an application to be able to access and edit their user profiles (Application A). The problem is that the user objects (entities, dao, beans) are handled in a separate application (Application B) which is specifically for managing user accounts. Importing the java sources for App B into App A could be messy and might need configuration of the persistence unit and connection. I'm thinking it would be better to inject an EJB from App B to App A to query the user DB and return the results so a user profile form is rendered in App A.
I know how to inject EJBs within the same application, but I'm not so sure about how it's done across different applications or even if that's the most advisable way to achieve what I want. it's better practice to inject an external EJB into App A or simply import the classes from App B and use those.

Because there's little information that actually explains application servers in the real world, For one domain at www.url.com:
- How many application servers are there if there are multiple applications hosted on this domain? Ie. url.com/app1, url.com/app2, etc.?
- How many web servers will there be?
- How would I make one physical server handle all requests for one of the above applications?
- How would one make static content a standalone application built with angularJS? Not static content served by servlets.
I question this as I have not yet succeeded in deploying a working ruleset for use with intranet based applications. I have verified the ruleset is working with external internet java apps so it is being deployed correctly just doesn't steer Intranet based apps to the correct version.
