IDL sequence, java.lang.OutOfMemoryError
Hi! This is what I'm doing: In a Java Applet I read a textfile into a Sting[]. Then I send the Sting[] to my component. In my IDL file I have typedefed a sequence of strings (typedef sequence < string > StringArray). This is an unbounded sequence because I don't know how many strings there will be. This works fine until the texfiles I read is over 15.000 rows (one row->one string in the sequence) or the file is larger than 930k. Then I get a java.lang.OutOfMemoryError on the clientside(in my other question to the newsgroup the java.lang.OutOfMemoryError occurred on the serverside.) Is there some limit to IDL sequences??? /Alexander Bj�rneheim

Check if the JVM you are using on the client has a maximum Java heap size. You are limited by available Java heap memory.

The client is a signed Applet running in Netscape 4.5 on NT4 with 64MB of memory. The physical memory shouldn't be the problem. And the JVMs memory have I checked with java.lang.freeMemory() and java.lang.totalMemory() before and after the java.lang.OutOfMemoryError, and it seems ok. So this really confuses me. I'll check with http://www.optimizeit.com/ any other suggestions?? /Alexander Bj�rneheim a.bjorneheim@upright.se Evan Ireland wrote: > Check if the JVM you are using on the client has a maximum > Java heap size.
