I am working on Alfresco Web Content Repository. I am writing a portal application which uses alfresco web service api's to communicate to alfresco. I am writing code to download files from alfresco to local system. I am using PortletOuputStream as an output stream and using jboss Gate in portal as a portal server. But when i am downloading large files(greter than 63M) i am gettin Heap space error.
This problem can be solved by increasing jboss heap space.But i want to do without increasing that. Though i am reading in chunks i am getting this error.
Kindly let me know how to solve this
Thanks in advance

My we application is facing constant intrusions. It is hosted in windows server. I have posted my issues here before.
I have also update all the jars, but with no results.
Now what I found is that some unwanted files are upload uploaded in the server, which takes 100% CPU or making unknown activities to the server.
I guess they are uploaded from my web application of struts2. Jboss console is provided in details here. Now my question is if there is any way to stop uploading files via struts2
Thanks in advance
I have a web application configured as /myApp
Every time I push a new release, I am planning to deploy a new application version by renaming the war file a myApp##002 which results in /myApp##0002
The URL on my client: http://mywebsite.edu/myApp points to the latest version of my web application. Sometimes if the release contains some major bugs that impact only a part of our users we want the ability to direct them to the previous version of our website.
Now, I have created another version of my client that I want to point to the previous version of the web application instead but I am not sure how to do that. Can someone please shed some light on this? Thanks.
I am sure this question has been asked and answered before multiple times. But unfortunately, I am still not clear. Here is my issue.
I have a JSP, Servlet application which uses MySQL as the database. I have built the WAR file as well. Now I am in need of deploying this so it can be accessed online by anyone.
I looked into lot of areas including normal web hosting. However even though the services like DailyReazor are highly secured, they provide little for MySQL, around 250 MB for the package I selected.
Now I am looking into Amazon AWS. In AWS I am expecting to deploy my aplication and make it available online.The MySQL server should not contain limits like 250MB.
But I have never ever used this service AWS before. By reading various posts, I know that Elastic Beanstalk is the easiest way to go, but still not convinced about how to deploy it properly with database access and all. And in the other hand, will they give me a web address like "www.example.com" or will they simply provide an IP address?? I am also familiar with tomcat so I need to use it.
We will not upload files (images etc) at the moment, so I believe we can manage with around 20$ per month?
I really appreciate if someone can provide a clear guidance on deploying java web applications in Amazon, with the requirements I mentioned about MySQL, Global access and so on.
Amazon RDS for MySQL is a Database-as-a-service offerring from AWS. It is scaleable up to 3TB, and has scaleable IO as well. Of course it also depends on how much you prepared to pay. they manage the DB for you (backup etc). You get a URL to connect, credentials and you are set to go.
Amazon Elastic Beanstalk uses Tomcat. So you should be familiar with that. You upload your WAR file and specify what EC2 flavor you want (CPU/MEM etc). They launch a VM that is configured with Jva and Tomcat and deploy the WAR for you. You get an IP address.
Amazon Route 53 is the DNS service, where you can assign the IP address to your domain (assuming you have one)
I have coded a Jersey based java server which is all wrapped in one excecutable jar.
I am looking for a web host service in which i can deploy the jar and run it.
I saw some dedicated servers which can do this but this is overshooting the need, any suggestions?
As per your comment I understand that you created a web application with a Jetty embedded server.
I think the best solution for you in this case is to get a virtual machine host, install JRE, upload your *.jar and run it from there. Given firewall permissions and correct configuration you should be able to receive requests on the 80 port. Cons? It costs. A lot.
Most of the Java hosts have already a servlet container running (almost always Tomcat) and you can only deploy your web application in it. Having an embedded Jetty server messes up everything for you.
I strongly suggest you to detach your web application (or as you called it REST server) from Jetty and deploy the *.war in any of the multiple free Java hosts to test it online.
EDIT
Thanks to you I made a deeper research on the topic and found an interesting guide to deploy a web application with embedded Jetty server in Heroku. I've never tried it nor I know if its free, but maybe you can give a try.
Digital Ocean work pretty well for me. Their basic packages are really cheap and you get root control over your own machine, meaning you can host whatever you want without restrictions. The only downside is that they are pretty old school - you have to set up EVERYTHING yourself, including firewalls etc. There are a lot of guides available on their website though, which makes life a lot easier!

I know this is a touch redundant but I don't have voting or comment rights yet so this is the only method for me to communicate.
Digital Ocean is a solid choice. I am paying 5$ a month for a VM with 512 Mb Ram and 20 gigs of storage (which for my use is just fine.) I am still working on my first proper deploy but as stated above there are tons of tutorials to guide you through it. I have no prior command line experience but I've managed to get the server running, Created an SSH key, uploaded my landing page and have gotten a test project using Spark as the embedded server up and functional in a matter of a few hours. The Droplets are easily scalable from what I've seen. I'm still having trouble deploying an Rest based app with Postgres as the DB but it seems more to do with the ports in play than anything else. Keep getting 404s.
I am trying to create a web application which will allow the user to upload a file. The file will be encrypted and transferred to a web service via SOAP. The web service will carry out simple operations such as 'storeFileToCloud(byte[])' and 'downloadFile(string)'.
So far, using Google App Engine, I have created the web services, however, I'm not sure how to encode the file using SOAP. I've also created the form for the user to upload his/her file, but I'm stuck on what to do after this. Any tips or guides will be extremely helpful.
The tools I'm using include Java, Google App Engine and Eclipse Indigo.
JAX-RPC uses xsd:base64Binary. See the JAX-RPC Spec, chapter 10. You could probably do worse than copying them. Be aware that the size of the data will expand by about 33%.
