If you're using the Myfaces extensions Filter (what you probably do,
because you're able to upload files), your web.xml should contain
something like this:


<filter>
<filter-name>MyFacesExtensionsFilter</filter-name>

<filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
<init-param>
<param-name>maxFileSize</param-name>
<param-value>20m</param-value>
<description>Set the size limit for uploaded files.
Format: 10 - 10 bytes
10k - 10 KB
10m - 10 MB
1g - 1 GB
</description>
</init-param>
</filter>

java-programmer >> Max size for upload... thanks very much,
but i've already done it...my application web.xml is bit different and
this is the filter part

<filter>
<filter-name>ExtensionsFilter</filter-name>

<filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class>
<init-param>
<param-name>uploadMaxFileSize</param-name>
<param-value>10MB</param-value>
</init-param>
<init-param>
<param-name>uploadThresholdSize</param-name>
<param-value>100k</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>ExtensionsFilter</filter-name>
<servlet-name>FacesServlet</servlet-name>
</filter-mapping>

I'm using a jsf application that upload a file into a mysql db.
The file is read from an action method and converted into an array of
byte and the array of byte is put into mysql db.
When i upload a file of 3,4 MB everythings go well, when my file became
about 6,7MB...error!This is my eclipse error,i think i've to enlarge
heap size,but how can i do it?
I use TOMCAT Server 5.0 embedded with Eclipse......
This is the error...can you help me?

Yes, your analysis sounds correct. This is not a problem within
the web protocol (which is often the cause of truncated uploads),
but in the amount of memory available to the JVM on the server..

There are two strategies you might pursue to resolve it, but I am
not sure if either is suitable.

1. Write the file to disk as it is recieved, rather than store the
file contents in the JVM memory until it is completely uploaded.
2. Increase the memory size of the JVM on the server. This is
probably unnecessary (see 1.), problematic (if it is someone elses
server) and will still run out of memory (with still larger file
sizes).

java-programmer >> Max size for upload... Thanks Andrew...
but it's not clear for me...
what have i do?
When i upload the txt file my application convert it into an array of
byte like

byte[] data;

and later with these operations

Context envCtx = (Context) ctx.lookup("java:comp/env");
DataSource ds = (DataSource) ctx.lookup("java:comp/env/MysqlJNDI");

if (ds != null) {
Connection conn = ds.getConnection();
if (conn != null) {
PreparedStatement pst = null;
pst = conn.prepareStatement("INSERT INTO tbl(Data) VALUES (?)");
pst.setBytes(1, data);
pst.executeUpdate();
pst.close();
conn.close();
}
}

i put the array of byte into a mysql table.

What have i do to solve my problem?
Can you help me?please...

The UploadedFile class can do this automatically, I thought. It's bad
that it's so poorly documented.

Default heap size for tomcat is 32M or something. I think that is not
very much and (looking at my own projects), it's always a good idea to
increase this a little. The way it's done is different for Windows/Linux:
